Description

[0001] Mounting ring and pipe connection system

[0002] The invention relates to a mounting ring according to the preamble of claim 1, as well as a pipe connection system according to claim 10.

[0003] Pipes are often connected using pipe clamps. This requires, for example, ensuring that the connected pipe ends fit tightly together to prevent material transported through the pipes, especially fluids, from escaping at the joint. It is therefore common practice to place a corresponding mounting element between the two pipe ends to be connected. This mounting element is usually ring-shaped and can, among other things, serve as a seal.

[0004] The problem is often that several components have to be handled simultaneously during assembly, namely the two pipe ends, the pipe clamp and the seal.

[0005] Particularly when the pipe clamp is not yet fully tightened, but the tool for it, for example, needs to be applied with one hand, there is a risk that the other parts that were previously positioned will slip apart or fall down because they are difficult to hold all at once with the other hand. This is time-consuming and nerve-wracking and can result in the assembly process having to be started again. It can also happen that the seal does not fall down, but slips unnoticed during assembly. As a result, the connected pipe ends are then insufficiently sealed against each other. This problem also occurs when, for example, sieve elements, sensors or similar components are to be mounted at the connection point.

[0006] EP 2 598 785 B1, for example, discloses a clamping system for connecting a first and a second pipe. The clamping system comprises a clamp and a washer, with the washer being firmly connected to the clamp. The washer serves as a sealing element.

[0007] One problem here can be the firm connection between the washer, which serves as a seal, and the clamp. This makes it impossible or only possible to a very limited extent to manufacture the clamp and the washer from different materials. However, this is often precisely what is desired. For example, if the seal is to be made of a soft and plastically deformable material, but the clamp should be as strong and dimensionally stable as possible. If the two parts are firmly connected, different materials with different thermal expansion coefficients can lead to strong tensions between the components and ultimately to unwanted leaks. In this respect, it is more advantageous to design the seal and the clamp from different materials and as separate components. However, this brings with it the problem described above of difficult and potentially cumbersome and error-prone assembly.

[0008] The objective is therefore to provide an improved mounting ring that can be used in a pipe connection system. The assembly should be as simple and error-free as possible. At the same time, it should also be possible, for example, to manufacture a seal installed with the mounting ring from a different material than the connecting clamp and / or to mount additional components, such as screen elements, sensors, or the like, quickly, easily, and reliably at the connection point.

[0009] Main features of the invention are defined in the characterizing part of claims 1 and 10. Embodiments are the subject of claims 2 to 9.

[0010] In a mounting ring for a pipe connection system, wherein the mounting ring has a support ring and a functional ring, it is proposed that the support ring has at least one holding element for the functional ring and that the functional ring is rotatably mounted in the holding element. In this sense, a mounting ring is a device that can be used when connecting two pipes to prevent a material transported through the pipes from escaping at the connection point and / or to be able to mount further components, such as sieve elements, sensors or the like, at the connection point inside the pipes. The mounting ring can therefore be a sealing element. The connection of the pipes is preferably a connection in which the pipes are connected using a clamp, particularly preferably using a V-profile clamp.It is conceivable that the pipes have straight or flange-shaped end pieces that are connected to each other. However, the mounting ring can be used particularly effectively when two pipes are connected, where the first pipe has a funnel-shaped end piece and the second pipe has a biconical end piece that is inserted into the funnel-shaped end piece.

[0011] A pipe connection system is a set of components that can be used to connect two pipes together. The mounting ring is one of the components in this set.

[0012] The support ring supports the functional ring. The support ring of the mounting ring is designed in such a way that it can be secured in a component, preferably in a V-profile clamp, which is used to connect the two pipe ends. The further component is preferably also part of the pipe connection system. The support ring can, for example, be produced as a stamped and bent part, i.e. it is punched out of a material and then bent into shape. For example, the support ring can be punched out of sheet metal and the holding elements can then simply be bent inwards. The support ring can have a flat basic shape or a conical basic shape. If it has a flat shape, it can also be viewed as a circular disk. The shape of the mounting ring corresponds to the shape of the support ring.

[0013] If the mounting ring is conical, it is not limited to a specific angle, but rather, depending on the area of ​​application, any steep or flat angle of the cone sides is conceivable.

[0014] The functional ring is designed as a separate component and is held on the support ring with the help of the holding element. In the assembled state, the functional ring is arranged between the two pipe ends. It can form the seal. It is also conceivable for the functional ring to carry further components, such as sensors, sieve elements or the like. The further components can protrude from the functional ring into the space between the pipes. In a first embodiment, both the support ring and the functional ring essentially have the shape of an annular disk, with an essentially circular outer circumference, an annular section and a central, likewise essentially circular recess. If the functional ring takes on the function of a seal, it is also conceivable for it to be designed as a volume seal, at least in sections.

[0015] The retaining element is part of the support ring. For example, it can be hook-shaped or rail-shaped. It is preferably designed such that a gap or a space is formed between the retaining element and the ring portion of the support ring, into which the functional ring can be inserted. The retaining element can be formed integrally with the support ring. It is also conceivable for it to be mounted to the support ring in a form-fitting, force-fitting, or material-fitting manner, for example by soldering, clipping, crimping, or the like.

[0016] What is particularly advantageous is that the functional ring is held rotatably, i.e. movably, on the support ring. In this case, a rotatable mount means that the functional ring is held captively on the support ring. The two components cannot therefore come apart of their own accord. At the same time, the two components lie next to one another in such a way that their respective circle centers lie essentially one above the other and the ring disks are arranged essentially in parallel planes. This makes an imaginary axis possible that passes through the centers of the support ring and the functional ring and around which both components can be rotated. The support ring and functional ring can rotate independently of one another and in the same or opposite directions. In other words, the support ring and functional ring lie parallel to one another and can be rotated against one another.The functional ring has a slight amount of play when unassembled, yet is securely held in the mounting ring. This flexibility allows the mounting ring to easily adjust to the desired position. It is only finally secured by tightening the V-profile clamp, for example, and can then perform a sealing function. At the same time, the support ring and functional ring can be installed and aligned together during assembly. There's no need to manually guide and handle multiple components.

[0017] The mounting ring can have a simple form in the shape of a flat disc. Alternatively, the mounting ring can also have a conical shape that is adapted to the conical shape of a biconical end of a pipe or to a corresponding shape of a funnel-shaped end of a pipe to be connected to the biconical end of the first pipe. If the mounting ring has such a shape, at least the support ring has a corresponding conical shape. In this case, the functional ring preferably also has a corresponding conical basic shape. However, it is also conceivable for the functional ring to be made of a correspondingly elastic material that simply adapts to the basic shape of the support ring.

[0018] A particular advantage is that the functional ring can be made of a different material than the support ring. This allows the materials of the two components to be optimally matched independently of each other to the respective tasks they are intended to serve. Examples include rubber-coated metal seals used in battery cooling systems or stationary energy storage systems; multi-layer seals consisting of different material combinations and density layers, such as combinations of metal and mica or combinations of metal and graphite; general graphite seals; or seals made of cork or similar materials. It is also conceivable for the support ring to be made of a more dimensionally stable material than the functional ring.This allows the functional ring to adapt well to the gap between the two pipes to be connected, while the stable support ring simultaneously ensures that the mounting ring stays in the right place and does not slip. In this respect, the functional ring is preferably made of a softer material than the support ring. It is also conceivable for the functional ring to be made of a particularly heat-resistant material. It can be seen that, with regard to the different thermal expansion coefficients when using different materials for the functional ring and the support ring, it is advantageous if the functional ring and the support ring are not firmly connected to one another, but rather the functional ring is held movably on the support ring. In principle, a wide variety of materials and shapes are conceivable for the design of a corresponding seal.

[0019] In a preferred embodiment, the at least one holding element has an I-shaped profile. Such a U-shaped profile is particularly advantageous for enabling the rotatable assembly of the functional ring. A corresponding profile can also be C-shaped or V-shaped; what is important is that it is a profile with an upper leg that is part of the support ring and with a lower leg on which the functional ring rests. The lower leg is formed by the ring section of the support ring. The upper leg is placed around the outer edge of the functional ring in the assembled state. It is particularly advantageous if the functional ring, in the assembled state, is inserted into the U-shaped profile of the at least one holding element in such a way that a gap is formed between the free U-leg and the functional ring.In the simplest case, it is conceivable that the support ring is formed as a stamped part from a metal sheet, with the holding element initially extending as a strip-shaped extension from the outer circumference of the ring outwards, i.e. away from the ring center, and then being bent back towards the ring center during production of the support ring. The width and length of the strip-shaped extension and thus the width and length of the holding element can vary. The width is understood to be the extension along the circumference of the ring section, while the length is understood to be the extension in the radial direction relative to the radius of the ring section. In this respect, the holding element can be regarded as hook-shaped if it is narrower. If it is wider, it can also be regarded as rail-shaped.

[0020] It can be seen that it is advantageous if at least two retaining elements are provided. For example, two diametrically opposed retaining elements can be provided. However, it is particularly advantageous if several retaining elements are evenly distributed around the circumference of the support ring. Hook-shaped retaining elements, in particular, are more material-efficient and easier to manufacture than full- or partial-circumference retaining rails.

[0021] In other words: The holding element can be hook-like or rail-like. The holding element can extend along a section of the circumference of the support ring. Multiple holding elements can be formed at different points on the circumference of the support ring. The holding elements can be formed in pairs, opposite one another. The holding elements can be arranged such that they form a polygon. It is particularly advantageous if the sides of the polygon are of equal length. Then the holding force is distributed evenly over the circumference of the support ring and the functional ring. In any case, it is advantageous if the holding elements are arranged circumferentially on the support ring.

[0022] In a further preferred embodiment, the functional ring has a retaining collar and a sealing section. The retaining collar is preferably flat and has a surface parallel to the ring section of the support ring. The retaining collar is the part of the functional ring that engages with the retaining element. A gap is preferably formed between the retaining collar and the upper leg of the retaining element. This supports the mobility of the functional ring in the holder thus formed. The retaining collar and the sealing section are always formed as a single piece and differ only in their shape. While the retaining collar is flat and has a surface parallel to the ring section of the support ring, as described above, the sealing section is preferably curved. This offers the advantage that the retaining collar can retain its shape when pressure is exerted on the curved sealing section during assembly and tightening of the V-profile clamp.This reduces the risk of the functional ring slipping out of the support ring due to force-induced deformation when tightening the profile clamp. At the same time, however, an optimal seal can be created, which could not be achieved with a non-curved mounting ring or could only be achieved with significantly greater force. It can therefore be seen that it is advantageous if the retaining collar is located within the retaining elements. It is also advantageous if the sealing section is spring-loaded and / or if the sealing section has a curved shape.

[0023] In yet another embodiment, the functional ring has a support section. The support section can, for example, be designed as a continuation of the sealing section arranged towards the center of the circle. Like the retaining collar, the support section is also flat. If the mounting ring is used to connect a funnel-shaped end of a first pipe and a biconical end of a second pipe, the support section, in the mounted state, can rest against the outer wall of the biconical end of one pipe, while the sealing section simultaneously presses with its curvature against the inner wall of the funnel-shaped end of the other pipe. In this way, a good and stable seal can be achieved.

[0024] Regardless of the design of the functional ring, it is advantageous if the support ring has at least one clamping element. With the help of the clamping element, the mounting ring can be pre-assembled in the V-profile clamp. In this way, the mounting ring can initially be loosely but captively fastened in the V-profile clamp. During assembly, the V-profile clamp and the mounting ring can then be pushed onto the first of the two pipes to be connected simultaneously and as one component. It is advantageous if at least four clamping elements are formed. Three or more than four clamping elements are also conceivable. The clamping elements are preferably arranged evenly around the circumference of the support ring. The clamping elements are designed in such a way that the mounting ring can be secured to the V-profile clamp with the help of the clamping elements. The clamping element preferably has two clamping wings for circumferential clamping. The clamping wings are arranged in a V-shape.The clamping element also has a knee that supports the lateral support.

[0025] Furthermore, it is advantageous if the support ring has at least one first mounting element for securing it to a first pipe. This enables pre-assembly of the mounting ring on one of the two pipes to be connected. Using the support ring, the mounting ring can be pre-assembled in a V-profile clamp. The mounting ring can, for example, simply be clipped onto the end of the first pipe. More precisely: the support ring can be clipped onto the end of the pipe. The entire mounting ring and the pipe connection system, which consists of the profile clamp and mounting ring, can then be clipped onto the end of the pipe. For small pipes, this can be done with two or three fingers of one hand, while holding the pipe between the ring finger, little finger, and the ball of the hand, for example. Such pre-assembly of the mounting ring is of course also possible for larger pipes.It's also conceivable that the mounting ring could be pre-assembled and pre-positioned at the first pipe end in this way. This would then allow for one-handed assembly of the two pipes. It's clear that it's advantageous if the mounting element is a clip element or a spring element, for example.

[0026] Furthermore, it is advantageous if the support ring has at least one second mounting element for securing it to a second pipe. Using the second mounting element, the second pipe can also be easily clipped on. Both mounting elements then hold the support ring and thus the mounting ring in place between the pipes to be connected, even if the V-profile clamp has not yet been fully tightened. When the V-profile clamp is subsequently tightened, the mounting ring can align itself and find the optimal position so that it then sits really tightly. It can be seen that it is advantageous if at least two first mounting elements and two second mounting elements are formed. The mounting elements can extend along a section of the circumference of the support ring. Multiple mounting elements can be formed at different points on the circumference of the support ring.The mounting elements can be arranged in pairs, opposite one another. For example, the mounting elements can be arranged such that they form a polygon, with the sides of the polygon preferably being of equal length. This ensures that the holding force is distributed evenly around the circumference.

[0027] In one conceivable design variant, for example, it is provided that the holding elements, mounting elements and / or clamping elements are each formed in pairs at diametrically opposite positions along the circumference of the support ring. Such a symmetrical alignment leads to an even distribution of force, pressure and weight over the entire circumference of the mounting ring. Another advantage is an arrangement of the holding, clamping and mounting elements that extends in four main directions starting from the support ring: If you imagine the support ring as a circular disk, you can define a circular plane in which this circular disk lies. The circular disk has an outer circumference. From this plane and from the circumference, two different directions can be defined: from the plane upwards and from the plane downwards, as well as from the circumference outwards and from the circumference inwards towards the center of the circle.The main directions of the respective elements can then extend as follows: The holding elements are preferably oriented inwards from the circumference, with the open profile side in this direction. The clamping elements are preferably oriented outwards from the circumference. The mounting elements are oriented downwards or upwards from the plane, with similar mounting elements being oriented in the same direction. The angle at which the elements extend in the respective direction can be variable and adapted to the respective specific embodiment. In yet another embodiment, it is conceivable that the at least one clamping element simultaneously forms the at least one holding element. Such a clamping element can be referred to as a combined clamping and holding element.A corresponding support ring can then, for example, have at least one, preferably more than one combined clamping and holding element as well as at least one first and at least one second mounting element.

[0028] In any case, it is conceivable that the functional ring is a sealing element, as already mentioned above. The sealing element can be made of various materials and / or material combinations. Examples include rubber-coated metal seals, cork seals, graphite seals, or even multilayer seals made of a composite of metal and mica or metal and graphite. It goes without saying that this list is merely illustrative, and a multitude of other materials and material combinations are possible. The mounting ring is therefore suitable for a wide variety of applications.

[0029] In one embodiment, it is conceivable for the functional ring to have at least one, preferably two radially inwardly projecting, elastically deformable fingers. These fingers can be used to exert a preload on a flange to which the mounting ring is to be attached when positioning the mounting ring. Such preload can facilitate one-handed assembly.

[0030] In another embodiment, it is conceivable that at least one of the aforementioned elements arranged on the support ring—i.e., one of the holding elements, a clamping element, a combined clamping and holding element, a first mounting element, and / or a second mounting element—forms a pin element for a pre-positioning device. Alternatively, such a pin element can also be formed as an additional element on the support ring. In any case, such a pin element is designed such that it can engage in a groove formed, for example, on a flange of a pipe section to which the mounting ring is to be mounted.

[0031] In a further aspect, a pipe connection system for connecting a first pipe and a second pipe is provided, wherein the pipe connection system comprises a V-profile clamp and a mounting ring as described above, wherein the first pipe has a funnel-shaped end and the second pipe has a biconic end, and wherein the functional ring of the mounting ring, in the mounted state, is arranged between the inside of the funnel-shaped end of the first pipe and the outside of the biconic end of the second pipe, and wherein the support ring, in the mounted state, is arranged between the first pipe, the second pipe, and the V-profile clamp. It goes without saying that what has been stated above with regard to the mounting ring and its design also fully applies to the mounting ring of the pipe system mentioned here. In this respect, reference is made to what has been said above with regard to the design of the mounting ring.Such a pipe connection system offers numerous advantages. In particular, the mounting ring fits perfectly between the two pipe ends during installation. Thanks to the clamping and mounting elements, it can be pre-positioned on one pipe end along with the V-profile clamp. The second pipe end can then be easily inserted. The joined pipe ends can be held with one hand without any risk of the parts falling apart or the seal slipping.

[0032] In one embodiment, a pre-positioning device is formed between at least one tube and the support ring of the mounting ring, wherein the pre-positioning device comprises a pin element formed on the support ring and a groove formed on the first tube or on the second tube. The groove is preferably formed in the region of the respective tube end. During assembly, the pin element of the mounting ring can engage in the groove. In this way, the alignment of the mounting ring on the tube end can be simplified. In particular, the mounting ring can be locked to a certain extent in the correct position.

[0033] It is also conceivable that the pin element of the pre-positioning device is formed by the at least one holding element, the at least one first or second mounting element or the at least one clamping element of the support ring or as part of the at least one holding element, as part of the at least one first or second mounting element or as part of the at least one clamping element of the support ring.

[0034] Further features, details, and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. They show:

[0057] Fig. 9 shows a section of a 3D view of the variant of the

[0058] mounting ring.

[0059] Figures 1 and 2 show a cross-section through a mounting ring 10. The cross-section runs along the central axis M, which represents the central axis of the mounting ring 10, about which the mounting ring 10 is rotatable. The mounting ring 10 has a support ring 30 and a functional ring 20. Retaining elements 40 are formed on the support ring 30. The retaining elements 40 have a U-shaped profile with an upper leg 42 and a lower leg 43. The lower leg 43 is part of the support ring 30.

[0060] The functional ring 20 has a retaining collar 21, a sealing section 22, and a support section 23. The sealing section 22 has a curved shape. The retaining collar 21 rests on the lower leg 43 of the retaining element 40 and thus on the support ring 30. The retaining collar 21 is encompassed by the upper leg 42 of the retaining element 40. A free space 41 is formed between the retaining collar 21 and the upper leg 42 of the retaining element. By securing the functional ring 20 to the support ring 40 in this way with the aid of the retaining elements 40, the functional ring 20 is rotatably mounted on the support ring 20. In Fig. 1, the mounting ring 10 and thus the support ring 30 and the functional ring 20 have a flat basic shape.This means that the support ring 30 essentially has the shape of a circular disk, from which the holding elements 40 and any mounting and clamping elements not shown here can extend in the various spatial directions, as described in connection with Figures 3a to 5h.

[0061] In Fig. 2, the mounting ring 10 has a slightly conical basic shape. It can be easily fitted to the end of a biconical pipe section, as can also be seen in Figures 5a to 5h. The angle at which the walls of the cone are set can be as large or small as desired and is by no means limited to the angle shown as an example of approximately 45°.

[0062] Fig. 3a shows a schematic plan view of a support ring 30 of a mounting ring 10. Figures 3b to 3g show detailed views of the support ring 30 shown in Fig. 3a. Such a support ring 30 can be used in all mounting rings described both previously and subsequently.

[0063] The support ring 30 has a circular disk-shaped basic shape. It can be either flat or slightly conical. The support ring 30 has an outer circumference. On this outer circumference 31, several holding elements 40, clamping elements 50, first mounting elements 60, and second mounting elements 70 are formed.

[0064] The holding elements 40, clamping elements 50, first mounting elements 60, and second mounting elements 70 extend from the support ring 30 in various spatial directions. In Fig. 4b, it can be seen that there are four directions with respect to the support ring 30 that are of particular interest in this context. Fig. 4b shows a section along line DD of Fig. 3a. A first direction n extends upwards from the plane in which the circular disk of the support ring 30 extends. A second direction r2 extends downwards from this plane. A third direction ra extends outwards from the circumference 31 of the support ring 30. A fourth direction r4 extends from the circumference 31 of the support ring 30 to the center point M of the support ring 30.

[0065] Fig. 4a schematically shows an arrangement of the different holding elements 40, clamping elements 50, and first and second mounting elements 60, 70 in these four spatial directions. It can be seen that the four different elements 40, 50, 60, 70 each extend in different spatial directions n, r2, ra, r4. The holding elements 40 extend in direction r4. The clamping elements 50 extend opposite to the holding elements 40 in the direction ra. The first mounting elements 60 extend in direction H. The second mounting elements 70 extend opposite to the first mounting elements 60 in the direction r2. In the assembled state, the first and second mounting elements 60, 70 then extend essentially in the direction of the longitudinal axes of the two pipes to be connected, at least in the connection area. The holding and clamping elements 40, 50 extend more or less perpendicularly thereto, as can also be seen in Figs. 5a to 5h.

[0066] Figs. 3b and 3c show a section along line AA of Fig. 3a. A clamping element 50 is arranged in this area on the support ring 30. The clamping element 50 has two clamping wings 51 and a clamping elbow 52. The clamping element 50 extends essentially in the direction r3 from the circumference of the 31 of the support ring 30 outward.

[0067] Figs. 3d and 3e show a section along line BB of Fig. 3a. A first mounting element 60 is arranged in this area on the support ring 30. The mounting element 60 has two clamping spring elements 61, 62. These two clamping spring elements 61, 62 allow the mounting element 60 to be clipped to a first pipe end.

[0068] Figs. 3f and 3g show a section along line CC of Fig. 3a. A second mounting element 70 is arranged in this area on the support ring 30. The mounting element 70 has two clamping spring elements 71, 72. These two clamping spring elements 71, 72 allow the mounting element 70 to be clipped to a second pipe end.

[0069] 5a, 5c, 5e and 5g each show a cross-section through an assembled pipe connection system 11. For better orientation, Figures 5b, 5d, 5f and 5h additionally show the plane in which the section plane SS runs through the support ring 30 of the mounting ring 10 mounted in the pipe connection system 11. Fig. 5d shows the section plane SS in which the view in Fig. 5a is cut. Fig. 5f shows the section plane SS in which the view in Fig. 5c is cut. Fig. 5h shows the section plane SS in which the view in Fig. 5e is cut. Fig. 5g shows the section plane SS in which the view in Fig. 5h is cut.

[0070] Figs. 5a, 5c, 5e, and 5g each show a first tube 80 and a second tube 90. The first tube 80 has a cylindrical tube section 81 and a funnel-shaped tube section 82. The second tube 90 has a cylindrical tube section 93, a first conical tube section 92, and a second conical tube section 91. The second tube 90 therefore has a biconic tube end. The biconic tube end initially becomes wider than the cylindrical tube section 93 in the region of the first conical tube section 92. In the region of the second conical tube section 91, the biconic tube end narrows again. The funnel-shaped pipe section 82 of the first pipe 80 becomes continuously wider than the cylindrical pipe section 81 in the direction of the second pipe 90. The funnel-shaped pipe section 82 of the first pipe 80 is designed such that the second conical pipe section 91 can be inserted into the funnel-shaped pipe section 82.The inner shape of the funnel-shaped pipe section 82 essentially corresponds to the outer shape of the second conical pipe section 91.

[0071] The mounting ring 10 with its support ring 30 and the functional ring 20 is arranged between the funnel-shaped pipe section 82 and the second conical pipe section 91. A V-profile clamp 100 encompasses the connection area and rests against both the outside of the first pipe 80 and the outside of the second pipe 90.

[0072] In Fig. 5a, it can be seen that the clamping elements 50 engage in the V-profile of the V-profile clamp 100. The clamping elements 50 thus secure the support ring 30 in the V-profile clamp 100.

[0073] Fig. 5c shows that the first mounting elements 60 secure the support ring 30 to the first tube 80. The first mounting elements 60 clamp the support ring 30 to the funnel-shaped tube section 82. Fig. 5e shows that the second mounting elements 70 secure the support ring to the second tube 90. The second mounting elements 70 clamp the support ring 30 to the second conical tube section 91 of the second tube 90.

[0074] In Fig. 5g, it can be seen that the holding elements 40 hold the functional ring 20, as already described with reference to Figs. 1 and 2. It can be seen that the illustrated embodiment of the pipe connection system 11 is an embodiment that uses a mounting ring 10 as shown in Fig. 2. Of course, in further embodiments, as also described below, it is also conceivable that a mounting ring 10 according to Fig. 1 is also used in a corresponding pipe connection system 11.

[0075] Fig. 6 shows a cross-section through a mounting ring 10, as already shown in Figs. 1 and 2. Here too, the cross-section runs along the central axis M, around which the central axis of the mounting ring represents the central axis around which the ring can be rotated. Here too, the mounting ring 10 has a support ring 30 and a functional ring 20. The holding elements 40 provided in this embodiment are combined with the clamping elements 50. Here too, a U-shaped profile can be seen. The upper leg 42 is formed by the clamping wings 51 of the clamping element 50. The lower leg 43 is also designed as part of the support ring 30.

[0076] The functional ring 20 has a retaining collar 21, a sealing section 22, and a support section 23. The sealing section 22 has a curved shape. The retaining collar 21 rests on the lower leg 43 of the retaining element 40 and thus on the support ring 30. The retaining collar 21 is encompassed by the upper leg 42 of the retaining element 40.

[0077] Fig. 7 shows a plan view of a functional ring 20 of a mounting ring 10 (not shown in Fig. 7). The functional ring 20 shown can be combined with any of the previously described variants of the support ring 30 to form a mounting ring 10. The viewing direction in the top view shown extends along the central axis M of the mounting ring 10. It can be seen that the functional ring 20 has an outer section which forms the holding collar 21. In the mounted state, the holding collar 21 is held by the support ring 30, as shown above. The functional ring 20 furthermore has a sealing section 22 and a support section 23. In the exemplary embodiment according to Fig. 7, the functional ring 20 also has two fingers 24 which are aligned radially to the central axis M.

[0078] Fig. 8a shows a mounting ring 10 in which the support ring 30 has a pin element 60'. In this variant of the mounting ring 10, the holding element 40 and the clamping element 50 are each formed by a single element formed jointly on the support ring 30. The support ring 30 further has first and second mounting elements 60, 70.

[0079] In Figs. 8b and 8c, one can see how a pin element 60' formed on the support ring 30 engages in a groove 83. In the example shown, the groove 83 is formed on the first tube 80. A formation on the second tube 90 is also conceivable. Fig. 8a shows a plan view of a corresponding pre-positioning device, while Fig. 8b shows a section of the pre-positioning device.

[0080] It is conceivable both for the pin element 60' to be formed as an independent element on the support ring 30, and for the pin element (not shown) to be formed by the at least one holding element 40, the at least one first or second mounting element 60, 70 or the at least one clamping element 50 of the support ring 30, or as part of the at least one holding element 40, as part of the at least one first or second mounting element 60, 70 or as part of the at least one clamping element 50 of the support ring 30. Fig. 9 shows a perspective view of how the clamping element 50 holds the functional ring 20 with the aid of the clamping wings 51. Here too, the clamping element 50 has two clamping wings 51 and a clamping knee 52. It is formed in one piece with the holding element 40, which, however, is almost completely concealed by one of the clamping wings 51 in the perspective view shown in Fig. 9. The clamping element 50 is formed on the support ring 30.It can be seen that the clamping wings 51 are V-shaped. Furthermore, it can be seen that the clamping wings 51 hold the functional ring 20 in the area of ​​the retaining collar 21 on the support ring 30.

[0081] The invention is not limited to one of the embodiments described above, but can be modified in many ways.

[0082] For example, various additional components can be arranged on the support section 23 of the functional ring 20. In one variant, for example, a sieve element is conceivable, in another one or more sensors. It is also conceivable for the functional ring 20 to have no sealing section 22, but merely serve to mount one or more additional components in the region of the connection between the two pipes. The functional ring 20 can then, for example, consist entirely of the holding section 21, with the additional components being mounted on the holding section 21. The additional components can also be sensors, sieve elements, or the like.

[0083] It is also conceivable, for example, that both the first pipe 80 and the second pipe 90 have a flange-shaped end with a circular disk-shaped connecting piece extending outwards. The two pipes 80, 90 can then be aligned flat with one another when connected at the flange ends, with the mounting ring 10 being designed as shown in Fig. 1 and being arranged between the two pipe ends. In this embodiment, the clamping elements 50 also hold the support ring 30 firmly in the V-profile clamp, while the holding elements 40 hold the functional ring 20 rotatably in the support ring 30. The first and second mounting elements 60, 70 hold the support ring 30 and thus the mounting ring 10 in this variant, for example, at the flange-shaped ends of the pipes 80, 90.

[0084] It can therefore be seen in any case that in a mounting ring 10 for a pipe connection system 11, wherein the mounting ring 10 has a support ring 30 and a functional ring 20, it is provided that the support ring 30 has at least one holding element 40 for the functional ring 20 and that the functional ring 20 is rotatably mounted in the holding element 40. It can be advantageous if the functional ring 20 is made of a different material than the support ring 30. It is also conceivable that the at least one holding element 40 has a U-shaped profile. The functional ring 20 has a holding collar 21 and a

[0085] Sealing section 22. Furthermore, the functional ring 20 can have a support section 23.

[0086] It is advantageous if the support ring 30 has at least one clamping element 50. Furthermore, the support ring 30 can have at least one first mounting element 60 for securing to a first pipe 80 and / or at least one second mounting element 70 for securing to a second pipe 90. The holding elements 40, mounting elements 60, 70, and / or clamping elements 50 can each be formed in pairs at diametrically opposite positions along the circumference 31 of the support ring 30.

[0087] It can further be seen that in a pipe connection system 11 for connecting a first pipe 80 and a second pipe 90, wherein the pipe connection system comprises a V-profile clamp 100 and a mounting ring 10, wherein the first pipe 80 has a funnel-shaped end and the second pipe 90 has a biconic end, it is advantageous if the functional ring 20 of the mounting ring 10 is arranged in the assembled state between the inside of the funnel-shaped end of the first pipe 80 and the outside of the biconic end of the second pipe 90 and wherein the support ring 30 is arranged in the assembled state between the first pipe 80, the second pipe 90 and the V-profile clamp 100.

[0088] All features and advantages arising from the claims, the description and the drawings, including design details, spatial arrangements and method steps, can be essential to the invention both individually and in a wide variety of combinations.
