Abstract

The present invention relates to a compressible module for cable entry and pipe penetration. The module is formed of two base components 106, 206, 206a, 206b surrounding the cable or pipe. Frequently, a plurality of modules are accommodated in the frame (1, 210) together with at least one compressible unit (3). The module of the present invention has a non-rectangular cross-section. In order to accommodate a module of a non-rectangular cross-section, the frame 210 is often formed after the formation of the module. In some cases, the filler part 120 is used to fill an open space that may exist if the frame and module are not directly fused together.

Description

[0001] MODULES OF A PIPE OR CABLE LEAD-THROUGH HAVING ALTERNATING GEOMETRY [0002]

The present invention relates to a seal for a cable or pipe, a lead-through or a transition. The present invention particularly relates to a seal or a part of a transition piece having a peelable sheet for adaptation to the diameter of a cable or pipe to be received.

In the prior art, there is a cable transition portion with a frame in which a plurality of modules for receiving cables, wires or pipes are located. The module is made of an elastic material such as rubber or plastic and is thus compressible. Inside the frame, a number of modules are typically housed side-by-side in one or more rows with some sort of compression unit. When the compression unit is expanded, the compression unit is positioned between the frame and the module in such a way that the compressible module is compressed around the cable, wire or pipe. For ease of description, the term "cable" is primarily used herein, but it should be interpreted broadly and those skilled in the art will understand that such a representation usually includes a pipe or wire.

Another type of seal, cable transition, pipe penetration, etc., has a generally cylindrical shape and is received within the sleeve in the wall or within the opening in the wall. In order to function in a certain way, the seal must fit snugly in the opening or sleeve of the wall to be received and the seal must be adaptable to the actual mounting dimension. The mounting dimensions depend on the inner diameter of the sleeve or opening. The seal has a cylindrical, compressible body and the compressible body is axially compressed between fittings at both ends of the compressible body. The axial compression will cause the cylindrical body to expand radially inward and outward.

Moreover, the received pipe, wire or cable may have various outer diameters, and thus the module must be adaptable to cables or pipes having various outer diameters.

The two types of seals or transition portions described above are used in many different environments such as cabinets, technical shelters, junction boxes and machines. They are used not only in ships or offshore, but also in other industrial environments such as automobiles, telecommunications, power generation and distribution. Seals or transitions must be able to seal against fluids, gases, fires, rodents, termites, dust, moisture, etc., and may be used for cables, wiring, water, compressed air, A pipe or a load holding wire for different gases or liquids can be accommodated.

Components that accommodate the two types of single cables or the like described above often have packs of peelable layers or sheets therein. This layer or sheet is peeled until the inner diameter of the part is adapted to the outer diameter of the cable received in the part. The sheets are sufficiently strong to be secured together and at the same time loosely attached so that the sheets can be peeled one by one from the laminate or a plurality of sheets together. In some embodiments, there is an externally peelable layer or sheet, for example the outer diameter of the circular seal can be adapted to a particular opening or sleeve.

Those skilled in the art will recognize that the exact shape and configuration of the different parts, including the layers, can be modified without departing from the spirit of the present invention. For example, a pack of layers may have a cross-sectional shape other than a circular shape.

The purpose of the present invention is to provide an improved compressible module in some embodiments compared to modules of the prior art.

The present invention achieves the above objects by providing a compressible module according to claim 1 and a sealing system according to claim 7. Preferred embodiments are limited to the dependent claims.

8 is a plan view of a frame used in the equipment of Fig.

A seal or transition for a cable and / or pipe of the general type is shown in Fig. It has an outer frame 1 accommodated in a wall or any other type of partition wall. Within the frame 1, a plurality of modules 2 are arranged to accommodate a single cable or pipe, respectively. Moreover, the compression unit 3 is accommodated in the frame 1. [ The module 2 is separated by a stay plate 4 which is arranged to securely place the module 2 in the frame 1. The module 2 is a compressible part of the seal or transition. Each module 2 has a central blind 5, which is removed when the cable or pipe is received.

An alternative system comprising a frame is disclosed in a co-filed application entitled "Sealing System " filed by the applicant of the present invention. This application is incorporated herein by reference.

In another alternative embodiment, the seal, lead-through or transition portion of the present design may be referred to as " Lubrication of a Pipe or Cable Lead-Through ", filed by the applicant of the present invention Lubrication means as shown in the co-filed application is provided. This application is incorporated herein by reference.

Alternative embodiments of the module are described in "Eccentric Part of a Pipe or Cable Lead-Through "," Eccentric Part of a Pipe or Cable Lead-Through "filed by the Applicant, , "Pipe or cable lead-through blocks", "Pipe or cable lead-through with modular modules", "Pipe or cable lead-through blocks" , "A Pipe or Cable Lead-Through Having Modularized Modules" and "Pipe or Cable Lead-Through Modules with a Dimensioning Function" Quot; A Pipe or Cable Lead-Through Having Layers of Alternating Geometry "filed concurrently herewith. In one embodiment, the module is disclosed in a co-filed application entitled " Modules of Pipe or Cable Lead-Through Sticking Together "filed by the applicant of the present application . This application is incorporated herein by reference.

In Fig. 2, a module half corresponding to module 2 of Fig. 1 is shown. The module half has a base part 6 having a generally rectangular outer shape with a semi-cylindrical groove on one side. A plurality of peelable sheets (7) are accommodated in the semi-cylindrical groove of the base part (6). During use, the two module halves are placed with their grooves facing each other. Thus, the formed module has a central cylindrical opening in which a cable or pipe is received. When the cable or pipe is received, a suitable number of sheets 7 are peeled from each base part 6 to accommodate the inner diameter of the cylindrical opening of the module to the outer diameter of the cable or pipe to be received. Thus, when the module 2 is received in a cable or pipe, the blinds 5 are first removed and the multiple sheets 7 are peeled off. When all the pipes and / or cables are located in each of the modules 2, the compression unit 3 is activated. The function of the compression unit 3 is to expand inside the frame 1. As the compression unit is expanded, it compresses the module 2 made of a compressible material such as rubber. The module 2 is compressed in one direction and inflated in the other direction to urge the module 2 against the frame 1.

The sheets may be arranged in a number of different ways and may be referred to as " A Pipe or Cable Lead-Through Having Interconnected Layers "filed by the Applicant, Quot; A Pipe or Cable Lead-Through Having a Part Indicating Compression ", "Pipe or Cable Lead-through " , "Coating Between Layers of a Pipe or Cable Lead-Through" and "Identification of Layers of a Pipe or Cable Lead-Through" Quot; filed < / RTI > filed concurrently herewith. This application is incorporated herein by reference.

The illustrated modules are optimized with respect to the variety and ease of installation and are very successful in this respect. The invention, however, is directed to providing a compressible module and a sealing system comprising the module and providing improved quality for space efficiency.

For this purpose, Figure 3 shows a base component 106 for a compressible module according to a first embodiment of the present invention. These modules are optimized in terms of space efficiency and include two identical base parts 106. They will form a compressible module with a hexagonal cross-section at the time of assembly. The base part 106 has a groove for receiving a laminate of the peelable sheet 107. Figure 4 shows a base part 206 corresponding to a differently cut out, essentially identical compressible module. The direct advantage of having a hexagonal cross-section improves space efficiency because the space occupied by the base component material is small. The problem associated with a particular embodiment is that the hexagonal cross section is not compatible with the rectangular shape of the frame and therefore can not be included in the system shown in Figure 1 without some modification. This problem can be solved by the filler part 120 arranged to fill the voids caused by the above incompatibility (see FIG. 5). In a variation of this embodiment (not shown), the filler part is divided into base parts and a peelable sheet is provided, which can also be used in the cable delivery part and the pipe penetration part. In this way, the space efficiency can be further increased. Figure 5 is a perspective view of a facility configured for a rectangular opening using the module of Figure 4 and additional filler parts.

The use of a compressible module having a hexagonal cross-section may have the additional advantage of distributing the cables arranged in the module in a particularly desirable manner. It will be readily appreciated that three adjacent cables can be arranged in a regular triangle, and there are significant advantages in controlling the electromagnetic field in a three phase installation.

Figure 6 shows a compressible module 202 having a triangular cross section according to a third embodiment of the present invention. The triangular shape is formed by two base parts 206a and 206b and the two compressible modules can be arranged to form a square or a rectangle so that a conventional sealing system can be used without the need for filler parts .

Figs. 7 and 8 illustrate a facility using a module 208 formed of two base components similar to the base components of Fig. 3 or Fig. The module 208 is received in a frame 210 having a shape adapted to the shape of the module 208. Thus, in this case, in contrast to the embodiment of FIG. 5, the filler parts are not used.

In summary, by abandoning the rectangular cross section of the compressible module, an improved compressible module and associated sealing system is achieved by opening the possibility to optimize for new characteristics.
