Description

[0001] A SEALING MODULE AND A METHOD FOR CONNECTING A CONDUIT TO A PARTITION LEAD-THROUGH SYSTEM, A LEAD-THROUGH SYSTEM AND USE OF SUCH A SEALING MODULE

[0002] Technical Field

[0003] The present invention concerns a sealing module. More specifically the present invention is related to a sealing module for connecting a conduit to a partition lead- through system, wherein the sealing module comprises an axis and a compressible body having an axially extending through opening.

[0004] The present invention is also related to a method for connecting a conduit to a partition lead-through system. Also, the present invention is also related to a lead- through system for leading one or more cables through a partition. In addition, the present invention is also related to a use of a sealing module for connecting a conduit to a lead-through system. One or more sealing modules are used in a lead-through system. Such lead-through systems are used for leading conduits, cables and / or pipes through walls, ceilings, bulkheads and other types of partitions.

[0005] Background

[0006] Different types of sealing modules and lead-through systems are used to lead conduits, cables and / or pipes through a wall or other partition. To give a sealed lead- through some kind of seal is generally arranged inside a frame placed at an opening in the partition. One example of seals comprises a number of compressible sealing modules, wherein each such module is to receive a conduit, cable or pipe. Such compressible modules are normally arranged together with a compression unit inside the frame. By means of the compression unit the compressible modules are compressed in one direction in such a way that the compressible modules will seal inwards around the conduits, cables and / or pipes and outwards against the inside of the frame.

[0007] Lead-through systems for conduits, cables and pipes are used in many different environments, such as for walls, floors and ceilings of buildings, ships, rolling stock, etc., as well as for different industrial environments, such as, telecom, power generation and distribution, as well as marine and offshore. They may have to seal against fluid, gas, fire, rodents, termites, dust, moisture etc. Many receive cables for electricity, communication, computers etc. or pipes for different gases or liquids such as water, compressed air, hydraulic fluid and cooking gas. Also conduits, such as corrugated plastic conduits and similar are used for lead-through systems of this type. One problem with prior art sealing modules and lead-through systems for such conduits is that they are complex and expensive and / or that the sealing properties are unreliable.

[0008] Summary

[0009] In view of the above one object of the present invention is to provide an improved sealing module with efficient and reliable sealing.

[0010] The present invention is related to a sealing module for connecting a conduit to a partition lead-through system, wherein the sealing module comprises an axis and a compressible body having an axially extending through opening, characterised in that the sealing module comprises a conduit connector having at least one tubular portion, wherein the tubular portion extends in axial direction and have an exterior surface facing a radial direction, wherein said exterior surface of the tubular portion is arranged with a gap to the compressible body along the through opening for receiving an end of the conduit. Hence, the end portion of the conduit is received in the gap between the through opening of the compressible body and the conduit connector, so that the end portion of the conduit can be sealed against the compressible body while being supported by the conduct connector. The conduit may be a plastic conduit, such as a corrugated plastic conduit. Hence, the end portion of the conduit is enclosing the tubular portion of the conduit connector. The end portion of the conduit can be clamped between the compressible body and the conduit connector for efficient and reliable sealing between the compressible body and the conduit. The tubular portion of the conduit connector is arranged inside the conduit and contacts an interior surface thereof. The conduit connector can be attached to the compressible body, such as by mechanical fastening element(s), adhesive and / or by clamping. The compressible body can be formed as a single piece or can comprise first and second compressible body parts, such as first and second compressible body halves. Optionally, the first and second compressible body parts are identical. Each of the first and second compressible body parts can have a first end, a second end and a first side having an axially extending groove arranged from the first end to the second end, wherein the first sides of the first and second compressible body parts are facing each other, so that the grooves form the through opening of the sealing module.

[0011] The compressible body can comprise at least one slot for receiving a projection of the conduit connector for anchoring the conduit connector and fastening it to the compressible body. For example, each of the first and second compressible body parts can comprise a slot extending radially outward from the groove. The projection of the conduit connector can extend radially outward into the slot of the compressible body or each of the compressible body parts for efficient and reliable fastening of the conduit connector to the compressible body or the compressible body parts. For example, each of the first and second compressible body parts can comprise a first slot and a second slot, wherein the first slot is arranged for receiving a first projection and the second slot is arranged for receiving a second projection axially displaced in relation to the first projection. Alternatively, the conduit connector can be fastened to the compressible body or compressible body parts in another manner, such as by mechanical fastening devices or adhesives. The slot, if any, can be arranged for receiving an intumescent material or similar. The projection can form an interior space. Hence, the projection can be hollow, e.g. for receiving intumescent material. The interior space can be open in one direction, such as radially inward, for insertion of intumescent material, such as a sheet of intumescent material.

[0012] The conduit connector can comprise a first tubular portion and a second tubular portion, wherein at least the first tubular portion is arranged for connection to the conduit. The second tubular portion can be arranged in a similar manner as the first tubular portion. Then, the end portion of another conduit can be arranged on the second tubular portion in a similar manner as on the first tubular portion. Alternatively, the second tubular portion can be arranged for terminating the conduit. Then, the second tubular portion can be arranged for contacting the compressible body in the groove, i.e. being arranged without the gap for receiving the end portion of a conduit. The first and second tubular portions can be arranged coaxially. The first and second tubular portions can extend in opposite directions from the projection. The projection can be arranged between the first and second tubular portions, such as axially in the center of the conduit connector.

[0013] The conduit connector can comprise two connector halves put together to form the conduit connector. The connector halves can be formed with semi-tubular portions forming the first and second tubular portions of the conduit connector when the connector halves are put together. The connector halves can be connectable to each other by means of a snap-lock mechanism for easy assembly thereof.

[0014] At least one of the first and second tubular portions of the conduit connector can comprise at least one protrusion and / or at least one flexible retaining tab for engaging an interior surface, such as an interior corrugation groove, of the conduit. Hence, the conduit can be retained to or secured to the conduit connector, optionally detachably.

[0015] The conduit connector can be made of a different material than the compressible body or body parts. For example, the compressible body or body parts are made of an elastomer, such as rubber, TPE or similar. The conduit connector can be made in plastic material, metal or composite materials. The conduit connector can be made of a more rigid material than the compressible body parts. The material of the conduit connector can have a higher Shore A value than the compressible body or body parts. The material of the conduit connector can be harder than the compressible body or body parts For example, the material of the conduit connector is non-elastomeric.

[0016] The present invention is also related to a lead-through system for leading one or more cables through a partition, comprising a frame, at least one sealing module as set out above arranged within the frame and a conduit connected to the sealing module, wherein one end portion of the conduit is arranged in the gap, in contact with the compressible body and in contact with the exterior surface of the first tubular portion of the conduit connector. The conduit can be a corrugated plastic conduit. The present invention is also related to a method for connecting a conduit to a partition lead-through system, comprising the steps of a) providing, within a frame of the lead-through system, a sealing module having a compressible body, a through opening and a conduit connector arranged inside said through opening, b) inserting an end portion of the conduit in a gap between an exterior surface of a tubular portion of the conduit connector and the compressible body and bringing the end portion of the conduit into contact with the exterior surface of the first tubular portion, c) bringing the compressible body into contact with a radially outer surface of the end portion of the conduit for sealing thereof.

[0017] The present invention is also related to a use of a sealing module as set out above for connecting an end portion of a conduit, such as a corrugated plastic conduit, to a partition lead-through system.

[0018] Further objects and advantages of the present invention will be clear to a person skilled in the art when reading the detailed description below.

[0039] Description of Embodiments

[0040] With reference to Fig. 1, a lead-through system 10 for connecting at least one conduit 11 through a partition is illustrated schematically according to one embodiment. The lead-through system 10 is optionally also arranged for passing at least one cable 12 and / or pipe through the partition. Such lead-through systems are also called transits or transit systems.

[0041] The lead-through system 10 is arranged for connecting one or more conduits 11 through a partition in the form of a wall, a floor, a roof or a ceiling. The partition is not illustrated in the drawings. For example, the lead-through system 10 is arranged for connecting one or more conduits 11 in the form of plastic conduits, such as corrugated plastic conduits, to at least one side of the lead-through system 10 and thus at least one side of the partition. For example, the lead-through system 10 is simultaneously arranged for passing cables 12, such as cables for electricity, communication, computers etc., or pipes for different gases or liquids, such as water, compressed air, hydraulic fluid, cooking gas or other types of liquids or gases, through the partition. Conduits 11, cables 12 and pipes are led in an axial direction through the lead-through system 10.

[0042] The lead-through system 10 is arranged for receiving one or more sealing modules 13 for connecting the conduit 11 to the partition. The lead-through system 10 also comprises a compression unit 14 and optionally stayplates 15. For example, the compression unit 14 and the stayplates 15, if applicable, are of conventional type. For example, the compression unit 14 is a conventional wedge.

[0043] Each of the sealing modules 13 for receiving the conduit 11 is compressible. The sealing modules 13 are resilient and comprises two opposite and compressible body parts 16a, 16b. Hence, the sealing module 13 comprises a first compressible body part 16a and a second compressible body pat 16b. For example, the compressible body parts 16a, 16b are in the form of module halves, wherein each compressible body part 16a, 16b is a compressible module half. For example, the first and second compressible body parts 16a, 16b are identical. Alternatively, the first and second compressible body parts 16a, 16b are formed as a single integrated piece, wherein the first and second compressible body parts 16a, 16b form a compressible body having the combined shape of the first and second compressible body parts 16a, 16b.

[0044] In the embodiment of Fig. 1, the lead-through system also comprises sealing modules 17 for receiving cables 12 or pipes. The sealing modules 13 arranged for connecting the conduit 11 are different from the sealing modules 17 for receiving cables 12 or pipes. The present invention is related to the connection of the one or more conduits 11 and the sealing modules 17 for receiving the cables 12 or pipes can be arranged in a conventional manner and are not described in detail herein. As can be seen in Fig. 1 the sealing modules 17 for cables 12 and pipes may be arranged in different sizes and a plurality of different sealing modules may be arranged in different configurations. The sealing modules 17 for cables 12 and pipes may have peelable sheets for adapting a diameter to the cable 12 or pipe in a conventional manner. Sealing modules 17 for cables 12 and pipes not used for leading a cable 12 or a pipe through the partition may be provided with a blind plug in a conventional manner.

[0045] The lead through system 10 comprises a frame 18, wherein the one or more sealing modules 13 are arranged within the frame 18, optionally together with the one or more stayplates 15 and the compression unit 14. For example, the frame 18 is of a conductive material, such as metal. For example, the frame 18 is of conventional type. The sealing modules 13 are compressible in the frame 18 by means of the compression unit 14. For example, the compression unit 14 is arranged within the frame 18 in a conventional manner.

[0046] The sealing module 13 for connecting the conduit 11 comprises a conduit connector 19. The conduit connector 19 is arranged for insertion into the conduit 11, wherein an interior surface of the conduit 11 is contacting an exterior surface of the conduit connector 19. An exterior surface of the conduit 11 contacts the compressible body parts 17a, 16b and the compressible body parts 16a, 16b are pressed toward the conduit 11 by means of the compression unit 14.

[0047] With reference to Fig. 2 another embodiment of the lead-through system 10 is illustrated schematically, wherein the lead-through system 10 comprises a plurality of sealing modules 13 for connecting the conduit 11, the frame 18, the compression unit 14 and one or more stayplates 15. The embodiment of Fig. 2 illustrates three sealing modules 13 for connecting the conduit 11 and one sealing module 17 for receiving a cable 12 or a pipe but the lead-through system 10 can comprise any suitable number of sealing modules 13, 17. For example, the lead-through system comprises a single sealing module 13, two or any suitable number of sealing modules 13, arranged in a single row or a single column or in a plurality of rows, wherein the size and shape of the frame 18, compression unit 14 and optional stayplates 15 are adapted thereto. In an alternative embodiment, the frame 18 is arranged for compressing the sealing modules 13, 17, wherein the compression unit 14 is not required. For example, the frame 18 comprises at least a first side part that is connected to adjacent second and third side parts by means of screws, wherein the second and third side parts extend perpendicular to the first side part, so that the sealing modules 13, 17 can be compressed inside the frame 18 by means of tightening of the screws.

[0048] With reference to Figs. 3 to 5, a compressible body part 16 is illustrated according to one embodiment. The compressible body part 16 has an axis A, a first end 20, a second end 21 and a first side 22 having an axially extending groove 23 arranged from the first 20 end to the second end 21. For example, the compressible body part 16 is formed as a rectangular block with the groove 23 arranged in the first side 22. Hence, the first and second ends 20, 21 extend in parallel radially extending planes. The first side 22 extends in an axial plane. The compressible body part 16 also comprises a second side opposite the first side 22 and lateral sides connecting the first side 22 and the second side. The lateral sides extend in parallel planes perpendicular to the first side 22 and the second side and perpendicular to the first end 20 and the second end 21. At least one portion of the groove 23 is arranged for receiving the end of the conduit 11. For example, the groove 23 is arranged for receiving one conduit 11 at the first end 20 of the compressible body part 16 and another conduit 11 at the second end 21 of the compressible body part 16. The groove 23 extends in the axial direction A. For example, the groove 23 is semi-cylindrical. Optionally, the groove 23 has a semicircular profile. The compressible body part 16 is resilient. For example, the compressible body part 16 is formed in natural or synthetic rubber, such as an EPDM rubber, optionally with additional fillers. Alternatively, the compressible body part 16 is formed in TPE. Two compressible body parts 16 can be put together to form the compressible body.

[0049] The compressible body part 16 comprises a slot 24. The slot 24 extends radially outward from the groove 23. For example, the slot 24 extends in a plane perpendicular to the axis A. Optionally, the slot 24 is arranged centrally in the compressible body part 16 in the axial direction. For example, the slot 24 forms a through opening from the groove 23 to the opposite second side of the compressible body part 16. In the illustrated embodiment, the slot 24 extends beyond the groove 23 in the lateral direction, i.e. perpendicular to the axial direction, so that the slot 24 has a width bigger than the diameter of the groove 23. The extension of the slot 24 in the radial direction is bigger than the extension of the groove 23 in the radial direction. A lateral extension of the slot 24, i.e. between the lateral sides of the compressible body part 16, is bigger than the lateral extension of the groove 23. For example, the slot 24 is rectangular. Alternatively, the slot 24 is semi-circular.

[0050] With reference to Figs. 6 to 9 the conduit connector 19 is illustrated according to one embodiment. The conduit connector 19 is arranged for contacting and optionally also retaining the conduit 11. The conduit connector 19 is formed of plastic material or sheet metal or composite materials. For example, the material of the conduit connector 19 is more rigid than the material of the compressible body parts 16a, 16b. For example, the material of the conduit connector 19 has inherent resilient flexible properties. The conduit connector 19 comprises a first connector half 25a and a second connector half 25b. Two connector halves 25a, 25b are arranged on top of each other to form the conduit connector 19. For example, the two connector halves 25a, 25b are similar. One connector half 25 is illustrated in Fig. 6 and the assembled conduit connector 19 is illustrated in Fig. 9. Alternatively, the conduit connector 19 is formed as a single integrated piece.

[0051] Each connector half 25 comprises a first semi-tubular portion 26 and a second semi-cylindrical portion 27. When two connector halves 25 are put together, the first semi-tubular portions 26 form a first tubular portion 28 and the second semi-tubular portions 27 form a second tubular portion 29. The first and second tubular portions 28, 29 are illustrated in Fig. 9. For example, the first tubular portion and the second tubular portion 29 extends in an axial direction and are aligned in the axial direction. For example, the first tubular portion 28 is similar to the second tubular portion 29. Alternatively, the second tubular portion 29 is different from the first tubular portion 28. The first semi-cylindrical portion 26 is, e.g. similar to the second semi-cylindrical portion 27.

[0052] The first and second connector halves 25a, 25b are connectable to each other through a lock mechanism, such as a snap-lock mechanism. In the illustrated embodiment, the connector halves 25a, 25b comprise cooperating tabs 30 and recesses 31 forming the lock mechanism. For example, the tabs 30 are resiliently flexible to form a snap-lock mechanism. Each connector half 25a, 25b may comprise protrusions 32 and recesses 33 for receiving the protrusions 32 of the other connector half.

[0053] At least the first tubular portion 28 is formed with one or more retaining tabs 34 for engaging corrugations inside the conduit 11. For example, the retaining tabs 34 are resiliently flexible due to the inherent properties of the material of the conduit connector 19. Hence, the retaining tabs 34 project radially outward from the outer circumference of the first tubular portion 28 and are resiliently flexible inward for allowing one or more corrugation ridges of the corrugated conduit 11 to pass and then engage into a corrugation groove thereof for retaining the corrugated conduit 11 to the conduit connector 19. For example, the first tubular portion 28 is formed with a plurality of retaining tabs 34 distributed circumferentially around the first tubular portion 28. For example, also the second tubular portion 29 comprises one or more similar retaining tabs 34.

[0054] The conduit connector 19 comprises a projection 35. For example, each of the connector halves 25a, 25b comprises the projection 35. The projection 35 extends in a plane perpendicular to the axial direction and perpendicular to the extension of the tubular portions 28, 29. The projection 35 is arranged centrally in the conduit connector 19 in the axial direction, such as in the center thereof. The first and second tubular portions 29, 29 extend in opposite directions from the projection 35. The projection 35 is arranged to be inserted into the slot 24 of the compressible body parts 16a, 16b. For example, the projection 35 has a shape substantially corresponding to the slot 24, such as rectangular. In the illustrated embodiment, the projection 35 is optionally formed with an interior space 36. The interior space 36 is open in a direction radially inward. With reference to Figs. 10 and 11 the sealing module 13 is illustrated according to one embodiment, wherein the sealing module 13 comprises the conduit connector 19 and the first and second compressible body parts 16a, 16b. In the illustrated embodiment, the first and second compressible body parts 16a, 16b are formed as two separate parts. Alternatively, the compressible body parts are formed as one integrated piece and the conduit connector 19 is moulded into the compressible body parts. The projection 35 is arranged inside the slot 24 and the tubular portions 28, 29 extend axially in opposite directions from the projection and the slot 24, so that a gap 37 is formed between the groove 23 and the exterior of the tubular portions 28, 29. Hence, the gap 37 extends radially from the exterior of the tubular portions 28, 29, or at least the first tubular portion 28, to the compressible body parts 16a, 16b inside the groove 23. The gap 37 extends circumferentially around the first tubular portion 28 and optionally also around the second tubular portion 29. The gap 37 also extends in the axial direction from the first end 20 of the compressible body parts 16a, 16b toward the projection 35 or all the way to the projection 35. In the illustrated embodiment, the first and second tubular portions 28, 29 projects in the axial direction from the compressible body parts 16a, 16b. For example, a length of the first and second tubular portions 28, 29 in the axial direction is bigger than a length of the compressible body parts 16a, 16b.

[0055] With reference to Figs. 12 and 13 the sealing module 13 is illustrated with a first conduit I la connected to the first tubular portion 28 and a second conduit 1 lb connected to the second tubular portion 29. For example, a single conduit 11 is cut in two, wherein one part of the conduit 1 la is connected to the first tubular portion 28 and the other part of the conduit 1 lb is connected to the second tubular portion 29. Hence, an end portion of the first conduit 1 la is brought onto the first tubular portion 28 and is inserted into the gap 37 surrounding the first tubular portion 28. The end portion of the first conduit 1 la is brought into the groove 23 of the first and second compressible body parts 16a, 16b. Hence, the end portion of the first conduit I la is brought into the through opening formed by the grooves 23. The end portion of the first conduit 1 la is brought in the axial direction into the gap 37. The end portion of the first conduit I la is brought to enclose the first tubular portion 28. The end portion of the first conduit I la is brought into contact with the compressible body parts 16a, 16b in the groove 23, so that the compressible body parts 16a, 16b contacts the circumference, such as the entire circumference, of the end portion of the first conduit I la. The end portion of the first conduit 1 la is also brought to contact or engage the exterior surface of the first tubular portion 28. For example, the retaining tabs 34 are brought to engage corrugation grooves of the first conduit I la. The second conduit 1 lb is, for example, arranged in a similar manner at the second tubular portion 29.

[0056] An example of an assembly of the sealing module with the first and second conduits I la, 11b includes to provide the first compressible body part 16a and arranging the first connector half 25a in the first compressible body part 16a, so that the projection 35 is inserted into the slot 24 and the first and second semi-cylindrical portions 26, 27 are arranged with the gap 37 to the first compressible body part 16a. Then, the second connector half 25b is connected to the first connector half 25a, such as by the tabs 30 and the recesses 31. Alternatively, the first and second connector halves 25a, 25b are connected to form the conduit connector 19, wherein the conduit connector 19 is arranged in the first compressible body part 16a, so that the projection 35 is inserted into the slot 24 thereof. Alternatively, a conduit connector 19 formed as one integrated piece is arranged in the first compressible body part 16a. Then the second compressible body part 16b is placed on the conduit connector 19, so that the projection 35 is inserted into the slot 24 of the second compressible body part 16b, the groove 23 of the first compressible body part 16a faces the groove 23 of the second compressible body part 16b and the first and second tubular portions 28, 29 are arranged with the gap 37 for receiving the end portions of the first and second conduits I la, 1 lb. The sealing module 13 is positioned in the frame 18. For example, the sealing module 13 is positioned in the frame 18 after assembly or is assembled inside the frame 18. Similarly, the first and second conduits I la, 11b may be connected to the sealing module 13 before or after positioning of the sealing module 13 inside the frame. After connecting the first and second conduits I la, 1 lb to the sealing module 13, the sealing module 13 is compressed inside the frame 18 by means of the compression unit 14, so that the compressible body parts 16a, 16b are pressed against the end portions of the first and second conduits I la, 1 lb for sealing thereof while the conduit connector 19 reinforces said end portions of the first and second conduits I la, 11b and prevents them from deforming and leaking, also over time.

[0057] In the embodiment of Fig. 12 optional sheets of intumescent material 38 are arranged inside the interior space 36 of the projection 35. An example of a sheet of intumescent material 38 is illustrated in Fig. 14. For example, the sheet of intumescent material 38 has a shape corresponding to the interior space 36 of one of the connector halves 25a, 25b. Hence, the sealing module 13 comprises two sheets of intumescent material 38, one in the first connector half 25a and one in the second connector half 25b. The sheet of intumescent material 38 is, e.g. shaped with a rectangular outer periphery having a first side with a semi-cylindrical groove.

[0058] With reference to Figs. 15 to 17 an alternative embodiment of the sealing module 13 is illustrated schematically, wherein the second tubular portion 29 of the conduit connector 19 is arranged as a free end, such as for terminating the conduit 11 instead of being arranged to be connected to the end portion of the second conduit 1 lb. In Fig. 15 the first tubular portion 28 is connected to the conduit 11, wherein the second tubular portion 29 forms an opening into which cables or pipes can enter or exit from the sealing module 13. For example, the compressible body parts 16a, 16b are arranged as described above.
