    A HOUSING FOR A PIPELINE COMPENSATOR Technical domain
    The present invention relates to a piping system comprising one or more pipeline compensators for flexibly connecting pipes of the piping system. More specifically, the present invention relates to a protective housing for pipeline compensators.
    Background art
    A pipeline compensator, also referred to as an expansion joint, generally comprises a tubular flexible portion or bellows provided at both ends with a pipe connecting element, such as, for example, a flange, a hose clamp, etc. The pipe connecting elements are used to connect the pipe pipeline compensator at both ends to pipes. The flexible portion gives the pipeline compensator the required flexibility to follow the movements of the connecting pipes relative to each other, whereby these movements can be caused, for example, by thermal expansion, vibrations, etc. In this way, the pipeline compensation compensates for the movements of the connecting pipes, and prevents he that the connection he forms between the pipes is broken. The flexible portion of a pipeline compensator is usually a bellow in metal, a bellow in rubber, a bellow in PTFE or a bellow in textile.
    The disadvantage of such a type of pipeline compensator is that it is not very suitable for underground use. The reason for this is that the flexible portion of the pipeline compensator is not able to fully perform its function when it is covered with bottom material that interferes with the movements of the flexible portion, and therefore also that of the pipeline compensator.
    For this reason, pipeline compensators are used which are provided with a protective housing in the form of a tubular sleeve, as can be seen, for example, in CH557501A, GB1401998A, WO8201759A1, GB1531792A, CN102359683A, FR2410205A1 and CN102705613A. The sleeve prevents the covering bottom material from coming into contact with and pressing against the flexible portion such that the flexibility mesh is able to fulfill its function. With such a type of pipeline compensator, a first end of the pipeline compensator is fixed relative to the housing in the vicinity of a first opening of the sleeve. A second end of the pipeline compensator is enabled to move within the sleeve such that a pipe connected to the second end of the pipeline compensator can move through a second opening of the sleeve.
    However, the disadvantage of this design is that the radius of action of the pipeline compensator is limited by the sleeve. To prevent bottom material from penetrating into the sleeve, the size of the second opening of the sleeve must closely match the nominal diameter of the pipe that passes through the second opening of the sleeve. This limitation of the size of the second opening limits the possible movements of the pipe passing through the second opening essentially to sliding in and out of the second opening in the direction in which the pipe passes through the second opening. Thus, for example, it is not possible for the pipe to move in lateral directions relative to the second opening, and it is only possible to change the slope of the pipe relative to this direction to a very small extent.
    Explanation of the invention
    An object of the present invention is to provide a housing for a pipeline compensator that increases the radius of movement of a pipe connected to a pipeline compensator located in the housing.
    This object is achieved in accordance with the invention by a housing for a pipeline compensator, also referred to as an expansion joint, which exhibits the technical characteristics of the characterizing part of the first claim.
    To this end, the invention provides a housing for enclosing a pipeline compensator connected to pipes of a predetermined nominal diameter, the housing enclosing a retaining space for retaining therein at least a flexible portion of the pipeline compensator, the housing having a first opening through which a first pipe is connectable to a first end of the pipeline compensator such that they are in fluid communication with each other, and a second opening through which a second pipe is connectable to a second end of the pipeline compensator such that fluid communication with each other, wherein at least the second opening is significantly larger than a predetermined nominal diameter of an element arranged in the second opening and selected from the second pipe and the second end of the pipe fusion compensator, and wherein at least the second opening is provided with a cover means for closely surrounding the element located in the second opening, said cover means being movably mounted in the second opening such that it is movable along at least one lateral dimension of the second opening while the retaining space is substantially closed held
    The housing of the present invention offers the advantage that it allows a larger radius of movement for at least the Second pipe while the retaining space and therefore also the housing are kept closed, If the first opening is similarly provided for the second opening , but then with respect to a further element located in the first opening and selected from the first pipe and the first end of the pipeline compensator, the housing of the present invention also allows a larger and greater movement radius for the first pipe while the holding space and thus also the housing are kept closed.
    The greater movement radius of the second pipe is made possible by the fact that the second opening is significantly larger than a predetermined nominal diameter of the element located in the second opening. Because of its size, the second opening offers a considerable amount of space in which the element located in the second opening can move freely. This enables the element located in the second opening to move, for example, in lateral directions of the second opening, to change its slope in the second opening, and to move in and out of the second opening. The covering means which is movably mounted in the second opening and which therefore closely encloses the element located in the second opening, then ensures that the retaining space is kept bumped while the element contained in the second opening moves in the second opening.
    Therefore, unlike in casings for pipeline compensators known from the prior art, the size of the second opening need not be limited to the nominal diameter of a pipe that passes through the second opening to prevent material, such as, for example, soil material, penetrates into the holding space and thus into the housing. The housing of the present invention is thus particularly suitable for protecting a pipeline compensator that connects pipes of an underground pipeline system, while still allowing a large movement radius of the pipes connected to the pipeline compensator.
    As indicated above, the element contained in the second opening may be the second pipe, that is, for example, the tubular body of the pipe, a flange at the end of the pipe, or a specially provided portion of the pipe which is configured to move in the second opening while being closely surrounded by the lid means. The element located in the second opening may also be the second end of the pipeline compensator, i.e., for example, a pipe connection element, such as a flange, at the end of the pipeline compensator, or a specially provided portion of the pipeline compensator that is configured to move in the second opening while being closely surrounded by the lid means.
    In an embodiment of the housing according to the present invention, the second opening is sized to limit the movement of the element located in the second opening to a predetermined movement radius, wherein the predetermined movement radius is preferably determined by an action radius of the pipeline compensator.
    Measuring the second opening to limit the movement of the element contained in the second opening to a predetermined movement radius is a simple and advantageous way to adjust the housing such that the pipeline compensator is prevented from moving beyond its action radius. is operated by the movements in the second opening of the element located in the second opening.
    In an embodiment of the housing according to the present invention, the lid means is provided with a lid opening for closely surrounding the element located in the second opening.
    The inventor has found that the lid means with the lid opening is a simple and uncomplicated way to provide the lid means of the housing according to the present invention for tightly surrounding the element located in the second opening. It provides a simplified housing design.
    In one embodiment of the housing according to the present invention, the lid opening is sized to closely surround the element located in the second opening with a predetermined amount of play.
    Measuring the lid opening to closely surround the element located in the second opening with a predetermined amount of play offers two important advantages. A first advantage is that the lid opening is kept small to prevent material, such as for instance bottom material, from penetrating into the holding space of the housing via the lid opening. A second advantage is that the lid opening is sufficiently large to prevent the element located in the second opening from being pushed in some of the possible orientations of said element in the lid opening against the sides of the lid opening, which could possibly damage it. caused to said element and / or to the cover part.
    For an element which is located in the second opening and which only goes straight through the lid opening, for example, the size of the lid opening should only be a little bit larger than the size of said element so that the lid opening is the element which the second opening is closely surrounded. However, if the element located in the second opening has different slopes with respect to the cover opening in its different possible orientations, the size of the cover opening should be larger to prevent said element from being pushed against the sides of the cover opening.
    The possible orientations of the element located in the second opening are generally determined by the action radius of the pipeline compensator, since any orientation of said element that moves the pipeline compensator beyond its action radius can cause damage to the pipeline compensator,
    The predetermined amount of play should be determined based on the action radius of the pipeline compensator located in the housing, the dimensions of the housing and the location where the pipeline compensator will be placed in the housing.
    In an embodiment of the housing according to the present invention, the cover means comprises! a first part and a second part fixed to each other, the lid opening being arranged through both the first part and the second part.
    The fact that the cover means comprises a first part and a second part, and that both parts comprise a part of the cover opening is advantageous for mounting the cover means around the element which is located in the second opening. As a result, the first part can be positioned, for example, on one side of the element that is in the second opening, and the second part on another side of the element that is in the second opening, after which both parts are fastened to each other around it. to form a lid.
    If both parts are releasably attached to each other, then the construction of the cover means also offers the advantage that the cover means can be easily removed from their position around the element located in the second opening, for example for maintenance or replacement of the cover sealant .
    That the lid opening is arranged through both the first part and the second part is to be understood in the sense that the first part comprises a first part of the lid opening and the second part comprises a second part of the lid opening, whereby the first part of the lid opening and the second part of the lid opening together form the lid opening when the first part and the second part are attached to each other.
    In an embodiment of the housing according to the present invention, the cover means comprises! a first layer formed by the first part and the second part of the lid means, and a second layer formed by a third part and a third part of the lid means, the lid opening also being arranged through the third part and the fourth part and wherein the third part and the fourth part are both attached to the first part and the second part.
    The double-layered cover means offers the advantage of extra strength and stiffness, such that the cover means is able to withstand large forces, which are caused, for example, by the weight of a material, such as, for example, a bottom material covering the housing.
    The fact that the cover opening is also provided through both the third part and the fourth part of the covering means provides the same advantage of an easy assembly as discussed above with regard to the fact that the cover opening passes through both the first part and the second part of the cover part. cover is applied. As a result, the first part can for instance be positioned on one side of the element which is in the second opening, and the second part on another side of the element which is in the second opening, and the same for the third part and the fourth part, after which the first part and the second part are fastened against the third part and the fourth part to form the cover means.
    Attaching the third part and the fourth part of the cover means to both the first part and the second part of the cover means is an advantageous way to firmly connect the parts of the cover means to each other. Attaching the third part to both the first part and the second part also confirms the first part and the second part to each other, and also fixing the fourth part to the first part and the second part further reinforces the connection between the first part and the second part. In this way the first part and the second part also connect the third part and the fourth part firmly.
    In an embodiment of the housing according to the present invention, the first part, the second part, if present the third part and if present the fourth part, are releasably attached to each other.
    The fact that the different parts of the covering means are detachably attached to each other is advantageous for dismantling the covering means, for example for maintenance or replacement of the covering means.
    In the housing according to the present invention, the housing comprises a cover chamber in which the cover means is movably arranged, and wherein the second opening is arranged through the cover chamber
    The cover chamber in which the cover means is movably arranged and through which the second opening is arranged is a simple way to mount the cover means movably in the second opening.
    This allows the cover sealant to be easily configured to keep the holding space substantially closed by dimensioning the cover seal larger than the second opening, which also conveniently prevents the cover seal from being accidentally removed from the second opening.
    As a result, the housing can also be easily configured such that the lid belt is movable along at least one lateral dimension of the second opening, by dimensioning the cover chamber for this purpose relative to the cover means.
    In an embodiment of the housing according to the present invention, the housing comprises a first housing part and a second housing part which are attached to each other, preferably in a detachable manner.
    That the housing comprises a first housing part and a second housing part configured to be attached to each other is advantageous for introducing the pipeline compensator into the holding space of the housing when mounting the housing. In this case, only the pipeline compensator must be provided in the first housing part, after which the housing is repelled by attaching the second housing part against the first housing part.
    The fact that the housing parts are connected to each other in an accessible manner is advantageous for dismantling the housing, for example for maintenance or replacement of the housing, or for maintenance or replacement of the pipeline compensator. in an embodiment of the housing according to the present invention, the first opening is provided by a wall of the first housing part and through a wall of the second housing part, and the second opening is provided by a wall of the first housing part and through a wall of the first housing part second housing section.
    The fact that the first opening and the second opening are arranged through a wall of the first housing section and through a wall of the second housing section offers the advantage that the housing can be quickly and easily mounted around the pipeline compensator, the element to be mounted in the second opening of the housing, and if necessary, the further element to be arranged in the first opening of the housing. To this end, only the pipeline compensator must be provided in the first housing part, with the element to be arranged in the second opening arranged in the part of the second opening that passes through a wall of the first housing part, and if necessary with the further part in the element to be provided in the first opening is provided in the portion of the first opening that passes through a wall of the first housing part, after which the housing is closed by fixing the second housing part against the first housing part.
    That the first opening and the second opening are provided through both a wall of the first housing section and a wall of the second housing section, is to be understood in the sense that the first housing section has a first section of the first opening and a first section, respectively. of the second opening, and the second housing part comprises a second part of the first opening and a second part of the second opening, respectively. Therefore, the first portion of the first opening and the second portion of the first opening together form the first opening, and the first portion of the second opening and the second portion of the second opening form the second opening when the first housing part and the second housing part are attached to each other.
    In one embodiment of the housing according to the present invention, at least one of the housing and the cover means comprises a material selected from the list consisting of plastic, metal, steel, stainless steel, stainless steel of type 304 and stainless steel of type 316, preferably stainless steel, and more preferably stainless steel of type 304 or stainless steel of type 316.
    The inventors have found that steel, and more specifically stainless steel, is an advantageous material to give the housing and the cover means the required rigidity to support the weight of a material, such as, for example, a bottom material covering the housing, as well as the required stiffness to withstand distortion caused by the weight of this covering material. This makes the housing according to an embodiment of the present invention particularly suitable for underground use.
    Stainless steel offers the additional advantage that it is resistant to corrosion, in such a way that the firmness and rigidity of the housing are retained during the use of the housing and the cover agent, and not deterioration due to corrosion. in an embodiment of the housing according to the present invention, the first opening is provided in a similar manner to the second opening of the housing according to an embodiment of the present invention, but then with respect to a further element arranged in the first opening, and selected from the first pipe and the first end of the pipeline compensator, instead of the element located in the second opening,
    Thus, in this embodiment of the housing of the present invention, the first opening is at least significantly larger than a predetermined nominal diameter of a further element disposed in the first opening and selected from the first pipe and the first end of the pipeline compensator, and provided with a lid means for narrowly enclosing the further element located in the first opening, said covering means being movably mounted in the first opening in such a way that it is movable along at least one lateral dimension of the first opening while the retaining space is kept substantially closed. This embodiment of the housing according to the present invention thus offers the advantage that both the first opening and the second opening are enlarged in order to provide a greater movement radius to the element which is located in the second opening and the further element which is behind in the first opening but still sealed by the cover means movably mounted in each of the openings.
    Furthermore, the first opening and the covering means of the first opening can be arranged like the second opening and the covering means of the second opening of the embodiments of the housing according to the present invention discussed above, and thereby enjoy the same advantages. For example, the first opening can be sized to limit the movement of the further element located in the first opening to a predetermined movement radius, the lid means of the first opening can be provided with a lid opening for closely surrounding the further element located in the first opening, etc.
    In an embodiment of the housing according to the present invention, the first opening is sized such that the holding space is substantially closed when the first pipe is connected to the first end of the pipeline compensator via the first opening, preferably the position of the first end of the pipeline compensator is fixed with respect to the first opening.
    The housing according to this embodiment is thus preferably used for placing the pipe conduit compensator in the holding space in such a way that the position of the first end of the pipeline compensator is fixed relative to the housing, and more specifically at least with respect to the first opening of the housing is fixed. This can be done, for example, by attaching the pipeline compensator with its first end to the housing, by attaching the first end of the pipeline compensator to the first pipe located on the outside of the housing in such a way that the wall of the housing enclosing the first opening is tightly clamped between the first end of the pipeline compensator and the first pipe, or by providing means in the retaining space for fixing the position of the first end of the pipeline compensator. in the latter case, the first pipe is then introduced through the first opening into the holding space of the housing and connected there to the first end of the pipe conduit compensator.
    If the position of the first end of the pipeline compensator is fixed relative to the housing, it is not necessary to make the first opening larger to provide room for movement for the further element located in the first opening. In this case, it is therefore advantageous to measure the first opening for substantially closing the holding space when the first pipe is connected to the first end of the pipeline compensator via the first opening, which prevents material, such as, for example, bottom material, from passing through the first opening penetrates into the retaining device. If, for example, the first end of the pipeline compensator or the first pipe is arranged in the first opening, then the size of the first opening is preferably adjusted to the size of the first end of the pipeline compensator or the first pipe, respectively. Or if, for example, the first end of the pipeline compensator and the first pipe are connected to each other, with the pipeline compensator located inside the holding space and the first pipe outside the housing, then the size of the first opening is preferably adjusted to the internal diameter of the pipeline compensator and the first pipe.
    To fix the position of the first end of the pipeline compensator relative to the first opening of the housing, the degrees of freedom for moving the pipeline compensator relative to the housing are limited. This offers the advantage that the design of the housing can be simplified, because the possible positions that the pipeline compensator can assume in the housing are limited by fixing the first end of the pipeline compensator.
    The invention further provides an assembly of a housing according to an embodiment of the present invention and a pipeline compensator, wherein at least one flexible portion of the pipeline compensator is located within the retaining space of the housing.
    In an embodiment of the assembly according to the present invention, a first pipe is connected to a first end of the pipeline compensator via the first opening of the housing, and a second pipe is connected to a second end of the pipeline compensator via the second opening of the housing housing.
    The invention further provides a pipeline system comprising at least one assembly according to an embodiment of the present invention.
    It should be apparent to those skilled in the art that the assembly and pipeline system of the present invention enjoy the same advantages as discussed above with regard to the housing of the present invention and its embodiments.
    The invention further provides a method for manufacturing the housing according to an embodiment of the present invention, the method comprising the steps of: providing plates, preferably stainless steel plates, to form the various parts of the housing, forming the plates into a predetermined shape of the different parts of the housing, mounting the molded plates together to form the different parts of the housing, and mounting the different parts of the housing together for mounting shape of the housing.

    Figures 1 and 2 show a housing 1 according to a first embodiment of the present invention. Figure 1 shows a perspective view of the housing 1 on the side of the housing 1 which comprises the first opening 4 of the housing 1. In this figure, a part of the housing 1 is cut away to show the holding space 7 of the housing and the second opening 5 of the housing 1 from the inside of the housing 1. Figure 2 shows a perspective view of the housing 1 on the side of the housing 1 which comprises the second opening 5 of the housing 1. Here too a part of the housing 1 is cut away, in this case to show the cover chamber 9 in which the cover means 10, in the form of a cover plate 10, is movably mounted.
    By way of illustration, Figures 7 and 8 show examples of a pipe fitting compensator 18 and a pipe 22, which can be used in combination with the housing 1 according to an embodiment of the present invention. The pipeline compensator 18 comprises a flexible portion 19, which is formed by a bellows in metal 19. The first end 20 and the second end 20 of the pipeline compensator 18 are here formed by at least the flanges 20 at the end of the pipeline compensator 18. This flanges 20 are provided with screw openings 21 through which the pipeline compensator 18 can be connected by means of screws or bolts to other components, such as for example a housing 1 according to an embodiment of the present invention, another pipeline compensator 18, pipes 22, etc. The screw opening 21 can be threaded such that a screw or bolt can be fixed in the screw opening 21 itself, or cannot be threaded, in which case a nut must be used to fix the bolt or screw in the screw opening 21. The pipe 22 comprises a tubular hollow body which is provided at both ends with n flanges 23, which are also provided with screw openings 24. In the following, the housing 1 according to the present invention will be described with reference to these examples of the pipeline compensator 18 and the pipe 22, but the. It should be understood that the use of the casing 1 of the present invention is not limited to such types of pipe loading compensators 18 and pipes 22. It should also be understood that there are other suitable ways of connecting the pipeline compensator or pipe to other components, such as by welding them together, by fixing them to each other with mechanical connecting means such as clamps, etc.
    The housing 1 has a first opening 4 via which a first pipe 22 can be connected to the first end 20 of a pipeline compensator 18. As a result, the pipeline compensator 18 can be arranged within the holding space 7 of the housing 1, the flange 20 is attached to the housing 1 at the first end 20 of the pipeline compensator 18. This can be achieved by means of screws passing through the screw openings 21 of the flange 20 at the first end 20 of the pipeline compensator 18 and by screw openings 6 opening the first opening. 4 are screwed around. In this way the position of the first end 20 of the pipeline compensator 18 is fixed relative to the housing 1, and more specifically at least relative to the first opening 4 of the housing 1. The first pipe 22 is then fixed with one of the flanges 23 at its end against the outside of the housing 1 at the first opening 4. This can be realized by the screws with which the flange 20 at the first end 20 of the pipe conduit compensator18 is fastened to the housing 1, also by screwing screw openings .24 of the flange 23 to the end of the pipe 22. Here, the first opening 4 is preferably approximately the same size as the internal diameter of the first pipe 22 and the pipeline compensator 18, such that the retaining space 7 is substantially closed at the first opening 4, and such that the flow of a fluid through the first pipe 22 and the pipeline compensator 18 is not impeded by the sides of the first opening 4.
    It should be noted that it is also possible to position the flange 23 of the first pipe 22 within the holding space 7 of the housing 1, and to attach it there to the flange 20 at the first end 20 of the pipeline compensator 18 and against the housing 1, but then from the inside of the housing 1. In this configuration, the first opening 4 preferably has about the same size as the size, or external diameter, of the pipe body passing through the first opening 4, such that the retaining space 7 is substantially closed at the first opening 4.
    Another possibility is that the flange 20 at the first end 20 of the pipeline compensator 18 is positioned outside the housing 1, and there is fixed to the flange 23 of the first pipe 22 and against the housing 1, but then from the outside of the housing 1. In this configuration, the first opening 4 preferably has about the same size as the first end 20 of the pipeline compensator 18 that passes through the first opening 4, such that the holding space 7 is substantially closed off on the side of the first opening 4 .
    The housing 1 also has a second opening 5, through which a second pipe 22 can be connected to the second end 20 of the pipeline compensator 18 which is located within the holding space 7 of the housing 1. This allows the second pipe 22 with its tubular body to be placed through the second opening 5. Within the retaining space 7, the second end 20 of the pipeline compensator 18 is connected to the second pipe 22, by means of screws screwed through both the screw openings 21 of the flange 20 at the second end 20 of the pipeline compensator 18, and through screw openings 24 of the flange 23 at the end of the second pipe 22 located within the housing 1.
    The size of the second opening 5 is larger than the size or diameter of the second pipe 22, or more specifically of the tubular hollow body of the second pipe 22. In this way the second pipe 22 is able to move freely within a predetermined movement radius provided by the second opening 5. However, in order to keep the holding space 7 substantially closed off from the environment, the second opening 5 of the housing becomes front of a cover media 10 in the form of a cover set plate 10. The cover set plate 10 is provided with a lid opening 15 for closely surrounding the hollow tubular body of the second pipe 22. The size of the lid opening 15 preferably has substantially the same size as the size or diameter of the tubular hollow body of the second pipe 22, optionally with a predetermined amount of play. In this embodiment, as can be seen in more detail in Figure 3, the cover means 10 is movably arranged in a cover the chamber 9, which is formed between a double wall 8 of the housing 1, and wherein the second opening 5 of the housing 1 passes through both walls 8 of this double wall 8. In this way the cover plate 10 is movably mounted in the second 5. When the cover plate 10 closely encloses the second pipe 22 and the cover plate 10 is movably arranged in the cover chamber 9, the cover plate 10 is thus able to control any movement of the second pipe 22 in any lateral dimension of follow the second opening 5 and into and out of the second opening 5, while still substantially closing the retaining space 7 of the housing 1 from the side of the housing 1 comprising the second opening 5.
    It should be noted that it is also possible to arrange the end of the second pipe 22, which in the example is formed by a flange 23, through the second opening 5 of the housing 1, and thereby also through the cover set opening 15 of the cover plate 10. It is herein preferred that the end of the second pipe 22 is adapted to be arranged in the cover opening 15, for example by making it sufficiently long for it to slide through the cover opening 15 in the direction in and out of the cover opening 15. When the end of the second pipe 22 is provided in the second opening 5 instead of the hollow tubular body of the second pipe 22, the size of the second opening 5 and the cover opening 15 is determined with respect to the end of the pipe 22 which is arranged in the second opening 5, and thus not with respect to the hollow tubular body of the second pipe 22 as described above.
    Another possibility is that the second end 20 of the pipeline compensator 18 is placed through the second opening 5 of the housing and the cover set opening 15 of the cover plate 10. The second end 20 of the pipeline compensator 18 is herein preferably adapted to be arranged in the cover seal opening 15, for example by making it sufficiently long for it to slide through the cover seal opening 15 in the direction into and out of the cover seal opening 15. the size of the second opening 5 and the cover opening 15 determined with respect to the second end 20 of the pipeline compensator 18 provided in the second opening 5. in this embodiment of the housing 1 the cover siphon 10 is movably mounted in the second opening 5 in such a way that the cover plate 10 is movable in the height direction of the second opening 5. This is achieved because the width of the cover chamber 9 is substantially the same is the width of the cover plate 10, such that the cover plate 10 can move only a very small amount in the width direction of the cover chamber 9, and because the height of the cover chamber 9 is significantly greater than the length of the cover plate 10, such that the cover plate 10 has room to move in the height direction within the cover chamber 9.
    In this embodiment, the second opening 5 itself is also formed in such a way that an element 22,20 selected from the second pipe 22 and the second end 20 of the pipeline compensator 18, which is arranged through the second opening 5, is only movable in the height direction of the second opening 5. For that purpose, the width of the second opening 5 is substantially the same as the size or diameter of the element 20.22 which is located in the second opening S, such that said element 20.22 only has one can move a little bit in the width direction of the second opening 5, and the length of the second opening 5 is considerably larger than the size or diameter of the element 20,22 which is located in the second opening 5, such that said element 20, 22 has room to move in the height direction within the second opening 5.
    The cover plate 10 can also be mounted movably in the second opening 5, in such a way that the cover plate 10 is movable in other lateral dimensions of the second opening 5. In the embodiment of Figures 1 and 2 this can for instance be realized by also the width of the cover clay chamber 9 is significantly larger than the width of the cover plate 10, and by making the width of the second opening 5 also considerably larger than the width of the element 20,22 which is located in the second opening 5.
    Another example of a housing 1 configured so that the cover member 10 is movable in any lateral dimension of the second opening 5 can be seen, for example, in Figures 5 and 6.
    The housing 1 according to this embodiment of the present invention is constructed in a similar manner to the housing 1 of the embodiment of Figures 1 and 2, but the housing 1 is cylindrical instead of beam-shaped, and the cover chamber 9 and the cover plate 10 are circular in place of rectangular. Here, the cover layer 9 has a diameter that is significantly larger than the diameter of the cover plate 10, such that the cover plate 10 has room to move within the second cover egg chamber 9 in any lateral dimension of the second opening 5. Also the second aperture 5 has a diameter that is significantly larger than the diameter of the element 22,20 located in the second aperture, such that said element 22,20 has room to move within the second aperture 5 in any lateral dimension from the second opening 5.
    It should be noted that it is also possible to configure the first opening 4 of the housing 1 in a similar manner to the second opening 5 of the housing 1. The first opening 4 thus has at least a size that is significantly larger than a nominal diameter of a first pipe 22 or the first end 20 of a pipeline compensator 18 located in the first opening, and it is provided with a cover means 10 movably mounted in the first opening 4.
    The cover plate 10 in the second opening 5 of the housing 1 of Figures 1 and 2, which can be seen in more detail in Figure 3, is composed of a first part 11 and a second part 12, which forms a first layer 101 of the cover space. 10, and a third part 13 and a fourth part 14, which form a second layer 102 of the cover plate 10.
