    [0002] Expansion compensating element
    [0003]
    [0004] Technical Field of the Invention
    [0005]
    [0006] The present invention corresponds to the technical field of pipe networks and in particular to an expansion compensating element to absorb the expansion thereof.
    [0007]
    [0008] Background of the Invention
    [0009]
    [0010] Pipe networks are subject to various factors that must be taken into account when designing and assembling them. One of these factors is the temperature changes, which generate deformations in the length of the pipes either by expansion, or by contraction, and can affect the joints between pipes and these with other elements.
    [0011]
    [0012] These temperature variations can be caused by an increase or decrease in the ambient temperature, or by the temperature of the fluid that flows through it.
    [0013]
    [0014] The existence of uncontrolled expansion in the conduits due to high temperatures generates destructive effects in the conduits, while the contraction due to exposure to low temperatures generates residual stresses in said conduits. These tensions are evident when disassembling a driving element, either a driving part or a team, because the task is difficult and the disconnection with respect to the conduction to which it was attached, produces sudden misalignments with respect to it, due to the seizure caused by tensions in the elements.
    [0015]
    [0016] It is therefore necessary to take this factor into account in the design of channeling networks and take measures to avoid it.
    [0017]
    [0018] For this, the design of the line is rethought either by modifying its layout, if possible, or by giving it greater elasticity artificially.
    [0019]
    [0020] In the state of the art, one of the ways used to provide elasticity to the pipes is with the introduction in the plot of changes of direction, especially by means of dilatation liras that represent breaks of the path in the form of omegas, in L, U or Z. The liras are based on arranging a series of fixed and mobile anchors so that they allow the conduction to be dilated due to the temperature effect sufficiently to avoid excessive tensions.
    [0021]
    [0022] These expansion lines are elements that allow relative displacements between their ends without entering into plastic deformations, but they present a fundamental problem because they take up too much space and this can be an inconvenience in some sections or areas of the network where it is necessary to place an element of expansion and not enough space available.
    [0023]
    [0024] In the state of the art there are other elements that provide elasticity to the pipes solving the problem of space of the liras. These are the expansion compensators, also called expansion joints, which are high-tech elements, mainly formed by flexible bellows, for the absorption of movements in a pipe system.
    [0025]
    [0026] However, these elements that absorb deformations very effectively, usually act in a maximum expansion range of about 2 to 3 cm, and in the case of those elements made with a rubber / elastomer, in a maximum expansion range of about 5 to 8 cm, so they can be favorable for metallic conduction elements, but not for the case of plastic conduction elements, since plastics have thermal expansion coefficients much higher than those of metallic ones and in particular, some expansion ranges that these pieces are not able to absorb.
    [0027]
    [0028] It has not been found in the state of the art an expansion compensating element that has a sufficient magnitude of expansion so that its use in both plastic and metallic conduction elements is adequate.
    [0029]
    [0030] Description of the invention
    [0031]
    [0032] The expansion compensating element, for pipe elements, which is presented here, comprises a first and second equal carrier, which have a tubular body with a first and second opposite ends and an emerging annular area of the first end with first through holes, where both first and second flanges are arranged symmetrically with the second end of both facing.
    [0033]
    [0034] This expansion compensating element has a tubular sleeve disposed on the outer surface of at least part of the tubular bodies of both first and second flanges, the inner diameter of the tubular sleeve being such that the tubular bodies can fit snugly inside thereof while allowing the longitudinal displacement of both flanges with respect to the tubular sleeve.
    [0035]
    [0036] Likewise, it comprises means for guiding the longitudinal displacement of each first and second flange holders respectively, which have for each one a guiding flange located on the tubular sleeve at one end thereof, with a few second through holes, and a set of axes parallel to the axis of both flanges each arranged through one of the second through holes, with a first free end and a second end fixed to the annular area of the flange holder.
    [0037]
    [0038] This expansion compensator element is designed to work as both a expansion compensator and a contraction compensator.
    [0039]
    [0040] When it acts as a expansion compensator, the circuit is directed to a high temperature fluid network. The pipe that has an initial length is mounted at room temperature and the compensator is mounted fully extended, thus, when the tube comes into operation with the fluid at high temperatures, the heat generates the increase in the length of the pipe and The compensator closes to absorb the increase in length.
    [0041]
    [0042] On the other hand, when it acts as a shrinkage compensator, the circuit is directed to a fluid network at low temperatures. In this case, the pipe with its initial length is mounted at room temperature, and the compensator is mounted completely closed so that when the conduction enters into operation with the cold liquid, the lowering of temperatures generates a contraction of the conduction and the compensator It opens to allow this contraction without generating tensions in the conduction.
    [0043]
    [0044] With the expansion compensating element proposed here, a significant improvement in the state of the art is obtained.
    [0045] This is thus achieved by an expansion compensating element capable of absorbing significant variations in the length of the pipes, with an expansion that can reach a maximum allowed expansion, in a range between 25 and 30 cm, thus being suitable both for metallic conduits as for plastic conduits, and especially for the latter, which have a higher expansion.
    [0046]
    [0047] With these dilating compensating elements it is possible to replace the dilatation liras, thus obtaining an absorption of the dilations and contractions of the pipes, by means of an element that occupies very little space, contrary to what happened with the lyres, so these elements can be placed in any network of pipes, without dimensional limitations.
    [0048]
    [0049] Another important advantage is that with this expansion compensating element it is possible to orient the holes of each of the flanges as we need, thus being able to correct orientation deviations. Thus, when a pipe holder or a flange-flange is welded to a pipe, it is welded to a part of the pipe by placing the screw holes in a certain position, but it is very likely that the operator at the time of installation it is detached and placed in a different position, so when the valve is to be placed, it is crooked, but thanks to this dilating compensating element it is possible to correct said orientation deviations.
    [0050]
    [0051] On the other hand, this expansion compensating element has an additional function and can act as a reel for assembly and disassembly. Thus, thanks to means for blocking the axes of the guiding means of the second carrier, the side corresponding to this second carrier is fixed and cannot move unless the axles are unlocked, while the opposite side in the that is the first flange itself is free to move absorbing the possible dilations and contractions. With this, if we place the expansion compensating element against the exit of an air conditioning machine for example, the machine will not move, so it is convenient that one side of the compensator is halfway out, and locked, in this way it can act as a reel for assembly and disassembly of this side, the other side being free to admit the expansion / contraction of the installation.
    [0052]
    [0053] It is therefore a very effective expansion compensating element, suitable for any type of conduits, especially those made of plastic material and which allows a double function of compensator and reel assembly-disassembly.
    [0054] Brief description of the drawings

    [0056] In order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, an integral part of said description is provided, a series of drawings where, for illustrative and non-limiting purposes, represented the following:
    [0057]

    [0067]
    [0068] Detailed description of a preferred embodiment of the invention
    [0069]
    [0070] In view of the figures provided, it can be seen how in a preferred embodiment of the invention, the expansion compensating element (1) for pipe elements proposed herein comprises a first and a second flange holder (2, 3) same, which have a tubular body (4) with a first and second ends (2.1, 2.2, 3.1, 3.2) opposite and an annular area (5) emerging from the first end (2.1, 3.1) with first through holes ( 6), where both first and second flanges (2, 3) are arranged symmetrically with the second end (2.2, 3.2) of both sides.
    [0071]
    [0072] In Figures 1 and 2 it is shown that the compensating element (1) comprises a tubular jacket (7) disposed on the outer surface of at least part of the tubular bodies (4) of both first and second flanges (2, 3), the inside diameter of the tubular jacket (7) being such that the tubular bodies (4) can fit snugly inside the same while allowing the longitudinal displacement of both flanges with respect to the tubular sleeve (7).
    [0073]
    [0074] In this sense, the tubular jacket (4) is arranged on more part of the first and second flange holders (2, 3) when said flanges are closed to allow a contraction or for having allowed a dilation and is arranged on less part of said flanges, if they are open, for being prepared to allow dilation or for allowing a contraction.
    [0075]
    [0076] This compensating element (1) for expansion also includes means for guiding the longitudinal displacement of each first and second carrier (2, 3) respectively, which, as can be seen in Figures 1 and 2, have a flange for each of them. guided (8) located on the tubular sleeve (7) at one end thereof, with a few second through holes (9), and a set of axes (10) parallel to the axis of both flanges each arranged through one of the second through holes (9), with a free first end (10.1) and a second end (10.2) fixed to the annular area (5) of the corresponding flange holder.
    [0077]
    [0078] These guide flanges (8) serve to guide the shafts (10) that prevent the compensating element (1) from being blocked due to misalignment, while these shafts (10) allow guiding the corresponding flange holder.
    [0079]
    [0080] In this preferred embodiment of the invention, as shown in Figures 2 to 4, the guiding means of the first and second flanges (2, 3), comprise for each of them a counter flange (11) with an inside diameter equal to the inner diameter of the tubular jacket (7), disposed at the end of the same next to the corresponding guiding flange (8).
    [0081]
    [0082] This counter flange (11) acts as a retainer, preventing the corresponding guide flange (8) from leaving the tubular sleeve (7), but does not block the flange, since it must be able to rotate in case it should be oriented to correct a misalignment between flanges.
    [0083] In this preferred embodiment of the invention, the axes (10) of the guiding means of the first and second flanges (2, 3) have a stop (12) at the first end (10.1), which prevents the exit of said first end (10.1) through the second through hole (9) of the corresponding guide flange (8).
    [0084]
    [0085] In this way, the element proposed here acts as a expansion compensator, but in other preferred embodiments, it can have a stop (12) only at the first end (10.1) of the axes (10) of a first flange holder ( 2), and also present means for blocking the shafts (10) that pass through the second holes (9) of the guiding flange (8) of the second flange holder (3). Thus, in that case, the compensating element (1) can function as an expansion compensator and, at the same time, as an assembly and disassembly reel.
    [0086]
    [0087] In order to make the expansion compensating element (1) tight, in this embodiment it comprises, as shown in Figure 4, sealing gaskets (13) between the tubular jacket (7) and the tubular body (4) of the first and second flanges (2, 3).
    [0088]
    [0089] In this preferred embodiment of the invention, the first and second flanges (2, 3) have the annular area (5) thereof configured as a flange, with the corresponding technical characteristics thereof, and in this case, both said annular zone (5) that forms a flange, such as the tubular body (4) from which it emerges, are formed by metallic material.
    [0090]
    [0091] Being the entire metallic compensating element, a greater simplicity of installation and a smaller flange diameter is achieved, which in turn allows a smaller diameter of valves to be connected. In addition, the flange is already DN of the piece, so there is no diameter reduction effect.
    [0092]
    [0093] Likewise, the thickness to be saved between flanges by the bolted elements is smaller, so that they can be shorter, reducing their cost. On the other hand, the thrust zone achieved covers the entire surface of the annular area of the flange holder, achieving a greater perpendicularity of the joint between the two that allows a parallel in the thrust plane between flanges, minimizing the problem of possible deformations in this union plane.
    [0094] In a second preferred embodiment of the invention, shown in Figure 5, the first and second flange holders (2, 3) comprise a flange (14) with third through holes (15), embedded inside the annular area (5), and arranged such that the third through holes (15) thereof are located coincidentally with the first through holes (6) of the annular area (5) of the flange holder (2, 3).
    [0095]
    [0096] The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are only to be understood as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
