    TECHNICAL FIELD The invention relates to a media-carrying component having a housing and at least one connection for connection to a counterpart of a second media-carrying component comprising a thread and a sealing component, wherein the at least one connection has an orifice-proximate end and a mouth-remote end, in one region a thread for providing a screw connection with the counterpart and a sealing component, which is designed to be complementary to the sealing component of the counterpart, between the mouth-near and the mouth-distal end.
    The invention further relates to an arrangement with such a media-carrying component.
    Background of the Invention For many applications, it is desirable or even necessary for a connection of two media-carrying components to be tight, for the media-carrying components to be aligned with each other and for the connection to be secured against rotation. In plumbing and heating technology, for example, one would like to assemble a distribution battery consisting of battery valve subparts and spacers so that the distribution battery is tight and the battery valve subparts are aligned parallel, the connections of the individual components having an anti-rotation, so that in particular the assembly is relieved. Preferably, the anti-rotation device does not prevent the rotation of the media-carrying components, but merely complicates them. In this case, the alignment of the media-carrying components to each other even after the creation of the connection is still possible.
    A conventional type of connection with the desired properties is the gated screw connection. As is generally known, in a screw connection, the thread of a connection is screwed to the thread of a counterpart, wherein one of the two threads is an external thread and the other thread is an internal thread that matches the external thread. For sealing a screw connection with sealing hemp this is applied to the external thread before creating the screw. The good properties of hemp as a sealing method in water installations are based on the fact that the sealing hemp swells in contact with water. As a rule, a bolted connection can be turned back at least a quarter turn without endangering the tightness. This is not the case with a threaded joint sealed with Teflon tape or a thread coating. However, hanging requires some effort from the installer, and it is important that it be done correctly to make the connection tight.
    There are some alternatives to this type of connection, but not all of the mentioned advantages. An alternative is the press connection of two pipe pieces. However, this type of connection is not solvable. In addition, an additional pressing tool is necessary. Another alternative is the screwing two pieces of pipe by means of a union nut, sealed with a flat gasket. It is disadvantageous that the axial distance between two adjacent valves is rigid and the flat gasket can be leaking - the sealing properties of gaskets are disadvantageous compared to O-rings, which is known for example from valve bonnets. The screw connection also has the advantages of mechanical strength and is also detachable (e.g., unlike press connections).
    US 2002/0175 519 A1 (John J. Mack et al.) Discloses an assembly with screw connections, comprising two housings which are interconnected by means of a clamping ring. The two housings have cooperating elements, such as intermeshing teeth, which prevent rotation of the housings against each other. In contrast to a gated screw connection, however, the housings can no longer be aligned with each other after creating the connection in this arrangement.
    SUMMARY OF THE INVENTION The object of the invention is to provide a media-carrying component which belongs to the technical field mentioned at the outset and which can be rotated even after the creation of a tight screw connection with respect to the counterpart, without jeopardizing the tightness of the screw connection, wherein the screw connection has an anti-rotation and the sealing of the screw requires no Hänfen.
    The solution of the problem is defined by the features of claim 1. According to the invention, the at least one connection of the media-carrying component has an elastic element attached to the housing, in order to achieve a friction-based securing against rotation of the screw connection. The elastic element is compressible in the direction of the thread axis and arranged and arranged such that it has at least one contact surface for contacting a region of the counterpart and a region of the housing in order to compress the elastic element in the direction of the threaded axis when creating the screw connection. The elastic element is preferably made of an elastomer, in particular preferably of ethylene-propylene-diene rubber (EPDM). Alternatively, it is made of a thermoplastic or of several components.
    The assembly of the inventive media-carrying component with the counterpart is easier and faster than the professional hanging of screw and carries a lower risk of error.
    A seal of the screw connection of the at least one connection of the inventive media-carrying component with a counterpart consists of a sealing ring and a respective bearing surface for the sealing ring on the at least one connection and on the counterpart. Preferably, the sealing ring is received in a first circumferential groove, wherein a surface of the first circumferential groove serves as a bearing surface for the sealing ring. The sealing component of the at least one terminal complements the complementary sealing component of the counterpart to a seal and consists of either the sealing ring and the bearing surface for the sealing ring on the at least one terminal or the bearing surface for the sealing ring on the at least one connection. The sealing ring is preferably made of an elastomer, in particular preferably of EPDM. Due to the good sealing properties, an O-ring is preferably used as a sealing ring. Alternatively, a flat gasket is used as a sealing ring. In a further alternative, the elastic element and the sealing ring are formed integrally with each other.
    The housing of the media-carrying component may be a simple piece of pipe or have a more complex shape, for example, if it is the case of a battery valve base. It may be made of any material, preferably a Cu alloy, e.g. Gunmetal or brass, stainless steel or plastic.
    The elastic element is compressed in creating the screw in the axial direction. It exerts a normal force on the contact surfaces, which corresponds to the restoring force of the compressed elastic element. As a result, the contact surfaces form friction surfaces which make it difficult to twist in both directions of rotation.
    The elastic element is preferably attached to the outer surface of the housing, so that it is not exposed to the medium and does not narrow the flow. Under this condition, the thread of the at least one connection is preferably an external thread. A construction of the at least one terminal, wherein the thread of the at least one terminal is an internal thread, would also be feasible, but much more expensive.
    For various applications, it is advantageous if the housing and the at least one connection are formed and arranged and cooperate with the counterpart that a screw of at least one connection with the counterpart is tight within an angular range of rotations about the threaded axis of at least one connection with respect to the counterpart, wherein the angular range has a size of at least one quarter turn, preferably of at least one half turn, preferably of at least one complete turn. For example, if the media-carrying component is an intermediate piece of a distribution battery, the battery-valve bases to be connected can be aligned in parallel if the individual screwed connections can be rotated by up to half a turn without leaking.
    When a thread cuts into a sealing ring, it is usually damaged and leaking. It is therefore advantageous if the housing and the at least one connection are designed and arranged in such a way and interact with the counterpart that cutting in of both the thread of the media-carrying component and the thread of the counterpart in creating the screw connection in the sealing ring is prevented. This is preferably ensured by a fixed stop, which limits the tightening of the screw. It may be possible to dispense with a fixed stop, if a sufficiently large torque would be necessary to cut it into the sealing ring with a thread. The torque required to tighten the fastener increases with the restoring force of the compressed elastic member and the associated frictional force of abutting contact surfaces of the elastic member and the housing and / or abutting contact surfaces of the elastic member and the counterpart.
    Due to the simplicity of the construction of the media-carrying component, the following two combinations of thread and seal component are preferred. In a first preferred variant, the thread of the at least one connection is an external thread, and the sealing component of the at least one connection comprises a first peripheral groove located on the side of the mouth-distal end of the external thread and a sealing ring received in the first circumferential groove.
    In a second preferred variant, the thread of the at least one terminal is an external thread, and the sealing component of the at least one terminal comprises a lying on the side of the mouth-near end of the external thread bearing surface for the sealing ring.
    The following two alternatives are also feasible. In a first alternative, the thread of the at least one connection is an external thread and the sealing component of the at least one connection comprises a bearing surface for the sealing ring lying on the side of the mouth-remote end of the external thread.
    In a second alternative, the thread of the at least one terminal is an external thread and the sealing component of the at least one terminal comprises a lying on the side of the mouth-near end of the external thread first circumferential groove and a received in the first circumferential groove sealing ring.
    The construction of the two preferred variants is simpler than that of the two alternatives, with the proviso that no thread cuts into the sealing ring when creating the screw.
    The screw can also be sealed on both sides of the thread. That is, the two preferred variants, the two alternatives, the first preferred variant and the first alternative or the second preferred variant and the second alternative can be combined.
    As an elastic element is particularly suitable an elastic sleeve which encloses a portion of the housing. This arrangement is expedient and makes it possible to create a large contact surface between the elastic element and the end face of the counterpart.
    Thus, the elastic sleeve can cause a friction-based rotation, the contact surfaces of the elastic sleeve and the housing and / or the contact surfaces of the elastic sleeve and the counterpart friction surfaces. In the preferred variant, the elastic sleeve is frictionally connected to the housing. In a particularly preferred variant, the rotation of the screw is based both on the friction between the elastic sleeve and the housing and on the friction between the elastic sleeve and the counterpart. However, the rotation of the elastic sleeve relative to the counterpart or with respect to the housing can also be prevented by design. In particular, the elastic sleeve can be partially connected firmly to the housing, in particular adhesively bonded or cast.
    Preferably, the at least one terminal has a second groove and the elastic sleeve on a projection, wherein the projection is received by the second groove. Thus, an axial fixing of the sleeve can be achieved, even if the sleeve is not firmly connected to the housing. The elastic element, in particular if it is an elastic cuff, has a hardness of preferably at least 70 Shore A, in particular of preferably at least 85 Shore A. Relatively hard elastic materials have the advantage of a longer life compared to softer elastic materials.
    The inventive media-carrying component is used in one embodiment as an intermediate piece for connecting and aligning two battery valve sub-parts. In this embodiment, it is advantageous if at least two connections are present on the media-carrying component and the housing has a drive profile for a wrench between the connections. The driving profile for the wrench simplifies the assembly of the screw connections between the battery valve subparts and the intermediate piece. Preferably, the drive profile is an octagonal profile. In a further preferred variant, the drive profile is a hexagonal profile.
    The invention further relates to an arrangement comprising a first media-carrying component according to the invention and a second media-carrying component, wherein the second media-carrying component has a counterpart to the at least one connection of the first media-carrying component for connection of the first with the second media-carrying component. This arrangement offers the possibility of a hanfree screw connection of the first media-carrying component with the second media-carrying component with the advantages of gehanften screwed connections mentioned above.
    With the help of an arrangement comprising a media-carrying component according to the invention and a first and a second battery valve lower part, a distribution battery can be assembled. For this purpose, it is necessary that the media-carrying component has at least two terminals and the first battery valve lower part is a counterpart to the first of the at least two connections for connecting the first battery valve lower part with the media-carrying component and the second battery valve lower part a counterpart to the second of at least have two connections for connecting the second battery valve base with the media-carrying component.
    The battery valve-bottom parts of the distribution battery can be aligned in parallel, without compromising the tightness of the compounds of the various components. Instead of the two lower battery valve parts, three or more lower battery valve parts can be connected to the corresponding number of intermediate pieces. Other media-carrying components can be connected to the inventive media-carrying component, such as water meters.
    From the following detailed description and the totality of the claims, there are further advantageous embodiments and feature combinations of the invention.
    BRIEF DESCRIPTION OF THE DRAWINGS The drawings used to explain the embodiment show:

    2 shows a housing of an intermediate piece according to the invention with two connections and an octagonal profile;
    3A shows a longitudinal section through the inventive intermediate piece with two connections and two counterparts mounted to the flex stop; and
    Fig. 3B is a longitudinal section through the inventive intermediate piece with two terminals and two counterparts mounted to the fixed stop.
    Basically, the same parts are provided with the same reference numerals in the figures.
    1 shows an oblique view of an embodiment of a distribution battery 1, comprising a first and a second battery valve lower part 2, 3 and an intermediate piece 4 designed according to the invention, which connects the two lower parts 2, 3 to one another and allows parallel alignment. The intermediate piece 4 comprises a housing 5, a first connection 100 for creating a screw connection with a first counterpart 120 of the first subpart 2 and a second connection 200 for creating a screw connection with a second counterpart 220 of the second subpart 3. The first connection 100 has a elastic collar 109 on to the rotation of the screw of the first terminal 100 with the first counterpart 120 of the first lower part 2. Analogously, the second terminal 200 has a further elastic sleeve on against rotation of the second terminal 200 with the second counterpart 220 of the second lower part 3. In According to the embodiment, the first and second terminals 100, 200 are made identical. Likewise, the first and the second counterpart 120,220 are identical. In the following, only the components of the first terminal 100 will be described in detail. To simplify the assembly and disassembly of the distribution battery 1, the housing 5 between the first and the second connection 100, 200 an octagonal profile 6 as a drive profile for a wrench.
    Fig. 2 shows an oblique view of the embodiment of the housing 5. The housing 5 is made of gunmetal and formed substantially tubular. The first connection 100 of the intermediate piece 4 comprises an end 101 close to the outlet, a distal end 102 and an external thread 103 at the end 101 close to the mouth for creating a screw connection with an internal thread 122 of the first counterpart 120.
    3A and 3B show longitudinal sections through the embodiment of the inventive intermediate piece 4 with the two counterparts 120, 220 in two assembled states. In Fig. 3A the situation of the minimum screw connection is shown, which is necessary for the screw connections to be fluid-tight. 3B shows the situation of the maximum possible screwing of the various components into one another.
    The first counterpart 120 of the first lower part 2, which cooperates in the assembled state with the first port 100, is also made of gunmetal and formed substantially tubular. The first counterpart 120 has at the end a cylindrical bearing surface 123 and, subsequently, the internal thread 122.
    At the external thread 103 of the first terminal 100 includes on the outer surface of the housing 5 opposite the mouth, a first circumferential groove 105 with a rectangular cross-section. The first circumferential groove 105 is designed cylindrically symmetrical, wherein the cylinder axis coincides with the threaded axis 104 of the external thread 103. In the first circumferential groove 105, an O-ring 106 made of EPDM is received as a sealing ring for sealing the screw connection of the first connection 100 with the first counterpart 120 by resting the O-ring 106 on the support surface 123.
    In the illustrated embodiment, the cylinder axis of the bearing surface 123 and the thread axis of the internal thread 122 of the first counterpart 120 coincide. Thus, the tightness of the screw is ensured by the interaction of the CD ring 106 with the support surface 123. In addition, the inner diameter of the support surface 123 is slightly larger than the inner diameter of the internal thread 122. This ensures that the external thread 103 for creating the screw through the Opening of support surface 123 fits.
    On the first circumferential groove 105 is followed by a circumferential recess 107, consisting of a cylindrical guide surface 107a for the support surface 123 and formed as a step stop 107b for the end face 121 of the first counterpart 120th die Sum axial Längen der Ausnehmung 107 und The first circumferential groove 105 corresponds to the axial length of the support surface 123. This prevents cutting in of the internal thread 122 when creating the screw connection in the O-ring 106.
    The tightness of the screw connection is ensured when the end face 121 is above the recess 107 and the O-ring 106 is thus completely received between the groove 105 and the bearing surface 123. The axial length of the recess 107 corresponds to the propulsion of the first counterpart 120 relative to the housing 5 with a rotation of the first counterpart 120 relative to the housing 5 about the threaded axis 104 by one complete revolution. Thus, the screw connection is fluid tight within an angular range of rotations about the threaded axis 104 of the first port 100 opposite the first counterpart 120, the angular range being one revolution (360 °). Figs. 3A and 3B show the situation at the beginning and at the end of this whole revolution.
    To the circumferential recess 107 of the first terminal 100 is followed by a cylindrical portion 108, followed by a second circumferential groove 110 having a rectangular cross-section. The elastic sleeve 109 of EPDM with a hardness of 85 Shore A surrounds the cylindrical portion 108 of the first port 100. It is also cylindrical in a section close to the mouth and runs conically towards the mouth-distal end 102. It has a circumferential projection 109 a, which is received by the second groove 110. As a result, an axial fixing of the elastic sleeve 109 is achieved. The geometry of the circumferential projection 109a is adapted to the geometry of the second groove 110, in particular, the muzzle distal side surface of the circumferential projection 109a forms a contact surface 109b of the elastic sleeve 109 for contacting a portion of the housing 5. This side surface is also the muzzle distal end surface of the elastic sleeve 109 and has an outer diameter corresponding to the minimum outer diameter of the octagonal profile 6. The sliding of the elastic sleeve 109 is carried out with a sleeve which is placed over the external thread 103 and facilitates the sliding.
    The elastic sleeve 109 is compressible in the direction of the threaded axis 104. In the situation illustrated in FIG. 3A, the mouth-near end face of the uncompressed elastic sleeve 109 lies over the mouth-remote side surface of the first circumferential groove 105. The inner diameter of the mouth-near end face of the elastic sleeve 109 is smaller than the outer diameter of the end face 121 of the first counterpart 120 This ensures that a contact surface 109c of the elastic sleeve 109 for contacting a portion of the end face 121 of the counterpart 120 is formed.
    When creating the screw connection, the first port 100 and the first counterpart 120 move towards each other at least until the flex stop is reached, in which the end face 121 of the first counterpart 120 contacts the elastic sleeve 109 for the first time. This situation is illustrated in FIG. 3A. When the first terminal 100 and the first counterpart 120 are screwed together more strongly than the flex stop, the elastic sleeve 109 is compressed between the contact surfaces 109b, 109c in the direction of the threaded axis 104. The restoring force of the elastic sleeve 109 resulting from the compression is exerted perpendicularly on both contact surfaces 109b, 109c. This results in friction at the contact surfaces 109b, 109c, which complicates the rotation of the first terminal 100 relative to the first counterpart 120 about the threaded axis 104 in both directions of rotation. The first connection 100 and the first counterpart 120 can be screwed together to a maximum extent up to the fixed stop, in which the end face 121 of the first counterpart 120 contacts the stop 107b. This situation is shown in Fig. 3B.
    Due to the above-described construction and arrangement of the various components of the embodiment, the screw connection for a screw connection between the flexible connection and the fixed connection is fluid-tight. Consequently, the media-carrying component 4 according to the invention enables a hemp-free screwed connection of the first connection 100 to the first counterpart 120, wherein the media-carrying component 4 can be aligned at any angle with respect to the threaded axis 104 relative to the first counterpart 120 and has a rotation-based anti-twist device ,
    The invention is not limited to the embodiment shown above. It can constructive features are performed differently and for the different components other materials (metals, alloys, plastics, composite materials, etc.) are used. In particular, can be used for the housing stainless steel, brass or plastic. The elastic sleeve can be made of EPDM with a different hardness, of a different elastomer, of a thermoplastic or of several components. Likewise, the O-ring may consist of a different elastomer than EPDM.
    The seal of the screw connection of the first connection with the first counterpart can be designed differently. The first circumferential groove and the sealing ring received therein may lie on the side of the mouth-near end of the external thread. The sealing ring can also be located in a receptacle of the first counterpart. In this case, the sealing component of the first connection consists of a bearing surface for the sealing ring. Finally, it should be mentioned that the screw connection can also be sealed on both sides of the thread with two sealing rings, wherein each of the two sealing rings is received either in the first port or in the first counterpart. In any sealing possibility, the housing and the first terminal may be formed and arranged and cooperate with the first counterpart that does not cut threads into a sealing ring when creating the threaded connection.
    The invention is not limited to intermediate pieces. If the media-carrying component has more than one connection, as in the example described above, then the connections can also be made differently. The elastic sleeve is fixedly connected to the housing in an alternative embodiment. Instead of the elastic sleeve, any elastic element can be used, which causes a friction-based rotation of the screw.
    As a drive profile for a wrench is also a hexagonal profile. Instead of the two battery valve lower parts, any other media-carrying components can be connected to the media-carrying component according to the invention, for example a water meter.
    In summary, it should be noted that the invention provides a hanfree screw of a media-carrying component with a counterpart that is easy to install and has the advantages of gehanften screw.
