Description

[Technical Field]

[0001] The present invention relates to a sealing device for sealing a pipeline assembly, the pipeline assembly having two pipeline units with a pipeline central axis and one tightening device, the pipeline unit having a pipeline with a pipeline outer surface, a pipeline end face and a pipeline outer diameter, and a pipe piece with a pipe piece inner diameter, the pipe piece having a flange portion with a flange portion end face and a pipe portion with a pipe portion inner surface, the tightening device tightens the flange portions of the pipe pieces of the two pipeline units to each other in the axial direction, and the sealing device has a seal arranged axially between the flange portion end faces of the pipe pieces when the sealing device is in use.

[0002] The present invention further relates to a pipeline system.

[0003] The present invention further relates to a method for manufacturing a sealing device for sealing a pipeline assembly. [Background technology]

[0004] Sealing devices in various embodiments, in particular in the form of O-rings, have been in the prior art for many years, but the drawback of these sealing devices is that they become brittle over time and the seal-specific information is no longer recognizable on the sealing surface of the sealing device, making it extremely difficult to track this information. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a sealing device and a method for producing the same, which significantly simplifies tracking of the sealing device and overcomes the disadvantages of the prior art. [Means for solving the problem]

[0006] This problem is solved in the sealing device of the aforementioned configuration by having a data carrier arranged corresponding to the seal, the data carrier having an electronic data memory to which seal-specific information can be written or written. The writable, preferably rewritable, data memory of the data carrier allows for flexible data management of the sealing device. The seal-specific information on the data carrier, in particular the RFID transponder, can be changed, deleted, or added at any time. Thus, in particular product data, maintenance data, production data, or service data are always available directly at the sealing device as seal-specific information. Advantageously, the sealing device is designed, in particular, for clamping pipe sections in accordance with DIN 32676.

[0007] In this case, the data carrier with the data memory may be arranged inside the seal or outside the seal. According to an advantageous embodiment of the sealing device, the data carrier arranged corresponding to the seal is arranged inside the seal. The data carrier arranged inside the seal is always arranged in a one-to-one correspondence with the seal, since the data carrier is assembled inside the seal. For example, the data carrier is essentially inseparably joined to the seal, i.e., the seal and the data carrier cannot be separated without destroying the seal.

[0008] According to an advantageous embodiment of the sealing device, the data carrier corresponding to the seal is arranged outside the seal. Preferably, the data carrier corresponding to the seal is arranged outside and in contact with the seal. In particular, this allows for a spatial separation between the seal and the data carrier. For example, the data carrier is provided at a different position from the seal, so that the seal and the data carrier do not have direct contact with each other. This prevents the medium, which is guided in a conduit assembly with a conduit unit and is to be sealed against the ambient environment, from coming into contact with the data memory. Aggressive media, such as acids and bases, may in this case particularly degrade the seal, but the data carrier is always readable, so that the information stored on the data carrier can be accessed at any time.

[0009] Advantageously, three different data carriers are available. A data carrier that is exclusively readable and written individually once by the supplier, but on which it is not possible to add, delete or overwrite seal-specific information later. For example, the production date and characteristics of the sealing device are treated as seal-specific information by the manufacturer. The data carrier can be written once by the manufacturer or customer and can be read any number of times. This gives the customer the possibility to store, for example, the installation date of the sealing device in a system as additional seal-specific information on the data carrier. Advantageously, the seal-specific information can only be read once it has been stored. This prevents the seal-specific information from being changed accidentally or accidentally, thereby improving the quality of the system. A data carrier that allows unlimited writing and reading of the data memory of the data carrier at the manufacturer's or customer's side. It is also possible to lock the data carrier for writing and / or reading by setting a write protection.

[0010] The sealing device is preferably used in pipeline structures present in installations in the bioindustry, pharmaceutical industry, chemical industry or food industry or in the field of hygiene.

[0011] In this regard, the data memory of the data carrier can be read, particularly contactlessly. Preferably, the data carrier of the sealing device is configured as an RFID transponder. The invisible communication between the RFID transponder and the writing / reading system provides a high degree of insensitivity to contamination, for example due to installation in a protected location, invisible integration into existing products, and simplified process optimization. Furthermore, each data carrier has a one-to-one correspondence based on a serial number that is set only once worldwide. This ensures precise correspondence to the individual production levels and complete individualization of production. Simultaneous reading of multiple RFID transponders in one work step is also possible, thereby accelerating the work process.

[0012] According to another advantageous embodiment of the sealing device, the seal is configured to form a predetermined transition between two pipeline units that are clamped together, so that no accumulation of residues of one type of medium flowing through the pipeline assembly or of multiple types of media flowing through the pipeline assembly occurs.

[0013] According to another preferred embodiment of the conduit assembly, the seal has a seal insert configured to set a minimum axial distance between two conduit units. Setting the minimum axial distance between two conduit units using a seal with a seal insert is advantageous because it allows the maximum pressing force of the sealing surfaces to be set. Furthermore, because the seal insert prevents the minimum distance between the two conduit units from being exceeded, post-processing of the conduit units, particularly the associated pipes, can be omitted.

[0014] Preferably, the seal insert has a seal insert end face configured as a stop. The seal insert end face configured as a stop allows for a simple implementation of limiting the minimum distance between two pipe units to be clamped. Particularly preferably, the data carrier is configured as part of the seal insert. The data carrier therefore forms part of the seal insert.

[0015] According to an additional advantageous development of the sealing device, the seal has a sealing surface extending circumferentially around the central axis of the sealing device, and a sealing portion having a data carrier is arranged on the sealing surface. This allows the data carrier, in particular a data carrier configured as an RFID transponder, to be better readable when the sealing device is in use. The clamping device is configured as a hinged clamp, and the sealing portion is preferably guided or guided outward by a hinged clamp joint of the clamping device. Preferably, the seal is made of rubber, preferably nitrile rubber or perfluororubber, silicone, polyethylene, or polytetrafluoroethylene.

[0016] Preferably, the problem is solved as set forth in claim 1. 8 The above-mentioned problems are solved by a pipeline system including the sealing device and a pipeline assembly according to any one of the above.

[0017] Furthermore, the object of the present invention is to provide a method as described above, wherein the sealing device has an electronic data carrier arranged in the seal, on which seal-specific information can be written or on which information is written, and wherein the seal is poured into the data carrier as an insert part; a) introducing a data carrier into a mold; b) pouring the sealing material into the mold; c) removing the manufactured sealing device from the mold. The method is characterized by having the following features:

[0018] This method allows for the rapid and cost-effective production of the sealing device. Preferably, the method implemented is injection molding or compression molding. Thus, the sealing device is preferably designed specifically for clamping pipe pieces according to DIN 32676. Preferably, in step a), a sealing insert with a data carrier is introduced into the mold. This has the advantage that no sealing parts are required, which can be very easily separated from the sealing device.

[0019] According to another advantageous embodiment, the sealing device produced by the method is a sealing device as claimed in claim 2.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. [Brief explanation of the drawings]

[0022] Unless otherwise stated, the following description relates to all illustrated embodiments of the sealing device 1 according to the present invention for sealing a pipeline assembly 2.

[0023] The pipe assembly 2 includes two pipe units 4 having a pipe central axis 3 and one clamping device 5. The pipe unit 4 includes a pipe 6 and a pipe piece 7, where the pipe 6 and the pipe piece 7 are aligned with the pipe central axis 3.

[0024] The conduit 6 has an outer conduit surface 8, a conduit end face 9, and an outer conduit diameter 10. Furthermore, the conduit 6 is configured to correspond to reference values ​​for pipe length and pipe bends, in the illustrated embodiment, a straight conduit 1. In other embodiments not shown, the pipe lengths and pipe bends are configured in other ways.

[0025] The stub 7 has a stub inner diameter 11 and includes a flange portion 13 having a flange portion end face 12 and a tube portion 15 having a tube portion inner surface 14. The flange portion end face 12 of the flange portion 13 is formed with a groove 16 that partially retains the sealing device 1.

[0026] Additionally, the tube section inner surface 14 has structure 18 in the form of ridges 19 .

[0027] The pipe stub 7 is axially inserted into the pipe 6 in the axial direction of the pipe central axis 3. The flange end face 12 and the pipe end face 9 are aligned flush with each other. In the illustrated embodiment, the pipe outer diameter 10 and the pipe stub inner diameter 11 have the same size.

[0028] In another embodiment not shown, the outer diameter 10 of the line 6 is larger than the inner diameter 11 of the stub 7. A press fit is therefore created when the stub 7 is axially inserted directly onto the line 6. Such a press fit establishes a force-fit connection between the line 6 and the stub 7.

[0029] The pipe unit 4 has a pipe stub 7 axially fitted into the pipe 6. In contrast to the assembly shown in Fig. 2, in Fig. 3 the pipe 6 is fixed in the pipe stub 7 by means of a press fit 20, in particular by radial expansion of the pipe wall, in the pipe unit 4. The pipe stub 7 is thereby connected to the pipe 6 in a force-fit manner. Other conventional connecting means, such as welding the pipe stub 7 to the pipe 6, are possible in other embodiments but are not depicted here.

[0030] The radial expansion is achieved by means of a tool, in particular a hole expansion tool, and is also referred to as expanding the conduit 6. After the radial expansion, the cross section of the conduit 6 is larger in the area of ​​the expansion than the original cross section of the conduit 6. Thus, due to the radial expansion of the conduit 6, in the area where the pipe piece 7 and the conduit 6 overlap, the expanded inner conduit diameter 21 is larger than the original conduit diameter 22.

[0031] Due to the formation 18 arranged on the inner surface 14 of the pipe section in the form of a ridge 19, not only a force-fit but also a form-fit connection is established between the pipe line 6 and the pipe piece 7 upon expansion of the pipe line 6. The formation 18 may also be configured in other ways, for example as a groove or the like.

[0032] In another embodiment not shown, the pipe section inner surface 14 and / or the pipe outer surface 8 are at least partially structured before the radial expansion of the pipe 6 .

[0033] A sealing device 1 having a sealing insert 23 is arranged between the pipe units 4 in the axial direction.

[0034] FIG. 5 shows a cross-sectional view of an embodiment of a conduit assembly 2 with a portion A in the region of two conduit units 4 clamped together.

[0035] The pipeline assembly 2 has a sealing device 1 arranged axially between flange portion end faces 12 formed on flange portions 13 of the pipe pieces 7. The sealing device 1 is configured to form a predetermined transition 24 between two pipeline units 4 that are fastened to each other. The predetermined transition 24 is formed by a crimping force acting on the sealing device 1 during fastening.

[0036] 5, section A, described below, in the region of the two mutually clamped pipe units 4, shows an enlarged view of the predetermined transition 24. The predetermined transition 24 reduces or eliminates the accumulation of residue or solids of one medium flowing through the pipe assembly 2 or of the plurality of media flowing through the pipe assembly 2.

[0037] Furthermore, the sealing device 1 has a seal insert 23. The seal insert 23 sets a minimum axial distance 25 between the two pipe units 4, and therefore, when the pipe assembly 2 is tightened, the two pipe units 4 are subjected to a crimping force determined by the minimum axial distance 25 determined based on the seal insert 23.

[0038] The pipeline assembly 2 is axially clamped by means of a clamping device 5. For this purpose, the flange portions 13 of the pipe segments 7 of the two pipeline units 4 are axially clamped to one another by means of the clamping device 5. In the illustrated embodiment, the clamping device 5 is preferably configured as a hinged clamp 26. With the clamping device 5 configured as a hinged clamp 26, the pressure acting on the sealing device 13, which corresponds to the pressing force in terms of area, can additionally be adjusted, for example, by means of a wing nut that closes the hinged clamp 26. The clamping device 5 may also be configured as a flange screw connection.

[0039] Alternatively, standard items such as gauges, valves and flaps may also be used as the line unit 4 in this case and may form the line assembly 2 together with other second line units 4 .

[0040] The seal insert 23 of the sealing device 1 has a seal insert end face 28 configured as a stopper 27. Thus, by means of the seal insert 23, a minimum axial distance 25 between the two pipe units 4 can be set or is set. The pipe end face 9 and / or the flange portion end face 12 adjoins the seal insert end face 28 of the seal insert 23 of the sealing device 1 in the tightened state of the pipe assembly 2. This allows the minimum distance 25 between the two pipe units 4 of the pipe assembly 2, and therefore also the crimping force acting on the sealing device 1, to be accurately adjusted.

[0041] The transition section 24, established by the crimping force determined by the sealing insert 23, is preferably configured so that the bend 29 forms an obtuse angle α with the pipe inner diameter 21. Particularly preferably, the obtuse angle α has an angle α of 100° to 170°, more particularly preferably 120° to 150°. This achieves a reduction or prevention of residues of the medium flowing through the pipe assembly 2 or of the media flowing through the pipe assembly 2.

[0042] The sealing device 1 has a data carrier 31 arranged in the seal 30, which has an electronic data memory 32 to which seal-specific information can be written or written. Preferably, the data carrier 31 of the sealing device 1 is configured as an RFID transponder 33. The data memory 32 of the data carrier 31 can therefore be written and / or read, particularly in a contactless manner, for example by an unillustrated RFID reading and / or writing device. Therefore, product data, maintenance data, production data, or service data, in particular, are directly available to the sealing device at any time as seal-specific information. For example, the date of manufacture, the date due for the next maintenance, the condition of the seal itself, the date of the last inspection, etc., can be stored in the data carrier 31.

[0043] The seal 30 is preferably configured as a flat seal, in which case the sealing material is, for example, elastomer, pressed fiber, aramid fiber, carbon fiber, mineral fiber, metal, copper, or other materials. A coated seal device 1, particularly a coated flat seal, is also suitable, in which the seal device 1 includes a core (any flat seal material, e.g., fiber composite, PTFE, etc.) surrounded by a PTFE or metal sleeve, preferably steel or a corrosion-resistant nickel alloy. The coating protects the core against the chemical action of the medium to be sealed. The seal 30 is preferably made of rubber, particularly preferably nitrile rubber or perfluororubber, silicone, polyethylene, or polytetrafluoroethylene.

[0044] The seal 30 of the sealing device 1 is a seal extending circumferentially around the sealing device centerline 34. Zhou surface 35, and a seal Zhou A sealing part 36 with a data carrier 31 is arranged on the surface 35. The sealing part 36 is configured in the form of a frying pan handle. In use, the pipe central axis 3 and the sealing device center line 34 coincide. In the embodiment not shown, for example, the sealing part 36 is not provided, so that the data carrier 31 is arranged inside the seal 30. Other arrangements of the sealing device 1 are also possible and conceivable.

[0045] In another preferred embodiment, the data carrier 31 is configured as part of the sealing insert 23. Such an embodiment is illustrated in Fig. 10. This allows the advantages of the sealing insert 23 and the data carrier 31 to be combined with each other. Furthermore, in this case, it is no longer possible for the data carrier 31 to easily come off during use.

[0046] 10, a data carrier 31 having a data memory 32 is arranged in the seal 30, which corresponds to the seal 30. The data carrier 31 is therefore always arranged in one-to-one correspondence with the seal 30. The data carrier 31 is embedded in the seal, so that the data carrier 31 is essentially inseparably connected to the seal 30. In particular, the seal 30 and the data carrier 31 cannot be separated from each other without destroying the seal 30.

[0047] The clamping device 5 is advantageously configured as a hinged clamp 26 , the sealing part 36 being guided on the outside by a hinged clamp joint of the clamping device 5 .

[0048] The sealing device 1 for sealing the pipeline assembly 2 has an electronic data carrier 31 disposed within the seal 30, on which seal-specific information can be written or written, and in this case the data carrier 31 serves as an insert 37 into which the seal 30 is cast in a method for manufacturing the sealing device 1. The method includes the steps of introducing the data carrier 31 into a mold, pouring a seal material into the mold, and removing the manufactured sealing device 1 from the mold.

[0049] Preferably, the method carried out is an injection molding method or a compression molding method. Particularly preferably, the sealing device 1 produced by the method is a sealing device 1 according to one of the sealing device 1 claims.

[0050] According to a further preferred method, in step a, the sealing insert 23 is inserted into the mould, the data carrier 31 being configured as part of the sealing insert 23 .

[0051] 4 and 5, a pipeline system 38 is shown, which in this case includes a sealing device 1 and a pipeline assembly 2. The sealing device 1 and the pipeline assembly 2 are preferably configured according to the description of the drawings.

[0052] A plan view of a third embodiment of the sealing device 1 with a seal 30 and a data carrier 31 is shown in Figure 11. In this case, the data carrier 31 with the data memory 32 is arranged outside the seal 30, against the outer seal side 39.

[0053] 12 shows a fourth embodiment of the sealing device 1, in which again a data carrier 31 arranged corresponding to the seal 30 and having a data memory 32 in the form of an RFID transponder 33 is arranged on the outside of the seal 30. Advantageously, the data carrier 31 arranged corresponding to the seal 30 is arranged on the outside, adjacent to the seal 30. The data carrier 31 is arranged on the sealing side 39 of the seal 30.

[0054] The data carrier 31 may also be spatially separated from the seal 30, as shown in the fifth embodiment of Fig. 13. The data carrier 31 is provided at a different location from the seal 30, here on the wall 40 of the chamber 41, so that the seal 30 and the data carrier 31 do not have direct contact with each other. This prevents a medium that is guided in the conduit assembly 2 with the conduit unit 4 and that is to be sealed off from the ambient environment by the seal 30 from coming into contact with the data carrier 31. In this case, aggressive media, such as acids or bases, may in particular degrade the seal 30, but the data carrier 31 is always readable, so that the information stored on the data carrier 31 can be called up at any time.
