15 20 25 30 35 distribution, as well as marine and offshore. The seals or passages may need to seal against liquid, gas, fire, rodents, ternites, darnm, moisture, etc. and may receive cables or wires for electricity, communications, computers, etc., pipes for various gases or liquids such as water, compressed air, hydraulic fluid and household gas or wires for power relief.
The parts that receive an individual cable etc. for both types discussed above often have a set of peelable layers or layers on the inside. The bearings or layers are peeled off one at a time until the inner diameter of the part is adapted to the outer diameter of the cable received in the part. The layers stick together strongly enough to hold together and at the same time loose enough for it to be possible to peel the layers from the stack, either one at a time or a number of layers together. In some embodiments, there are also peelable layers or layers on the outside, which makes it possible to adapt the outer dimensions of, for example, a circular seal to a specific opening or sleeve.
One skilled in the art will appreciate that the exact shape and appearance of the various parts, including the bearings, may vary without departing from the present invention.
For example, the bearing stack may have a different cross-sectional shape than circular.
It has been shown that even though the method of peeling layers is a changeable and flexible solution, it is still part of the assembly process that takes time. The present invention offers an inventive solution that reduces the time required during the assembly process, as well as a reliable method for determining the number of layers that must be peeled off.
Summary The present invention achieves the above objects by providing a compressible module according to claim 1, a method according to claim 6, and a sealing system according to claim 8. Specific embodiments are defined by the subclaims.
To this end, the present invention provides a compressible module for cable passages or pipe bushings, which receives one or two compressible modules surrounding each cable or pipe, the cable passages or pipe bushings being located either directly in an opening in a wall or other structural divider constituting the wall, or in a frame, whereby a barrier is formed by said one or more modules and at least one compression unit in the opening or frame, the compressible module having at least one of: at least one peelable layer for adapting to the diameter of a cable or a tube, which at least one peelable layer is arranged in a groove; and at least one peelable layer disposed on the outside of the module to conform to the dimension of the opening. The compressible module is characterized in that a peelable layer closer to the compressible module has a greater extent in an axial direction than a peelable layer further away from the compressible module. The inventive concept is to consciously use the peelable layers for dimensioning purposes; either to adapt to the dimensions of a cable or pipe or other service to be sealed or to adapt the external dimensions of the compressible module to an opening into which it is to be inserted. The inventive solution makes such an adaptation easily feasible, correct, and repeatable.
According to one or more embodiments, at least one peelable layer is flush with the compressible module at an axial end of the latter. In general, it may be sufficient for the inventive dimensioning function to be provided at one end of the compressible module.
According to one or more embodiments, a portion of a layer extending beyond an overlying layer is provided with an identification or dimensioning marking. The identification or dimensioning marking can facilitate both the installation and the control thereof. The installation can be simplified in such a way that once an adjustment has been made, identical installations can adapt to the same dimension, without the need to repeat the entire dimensioning procedure.
The present invention also relates to a method of arranging a cable or pipe in a compressible sealing module and dimensioning the sealing module to the diameter of the cable or pipe, the sealing module having a through hole in which peelable material layers are arranged to adjust the diameter of the through hole to the diameter of the cable or tube, a radially outer peelable layer having a greater extent in an axial direction than a radially inner peelable layer, comprising the steps of: inserting a cable or tube into the through hole of the compressible module until contact with a peelable layer is formed, remove the peelable layer at which contact was made with the cable or pipe and any layer radially inside it. This corresponds to a method of using the above device according to the first alternative.
According to another concept according to the invention, a method for arranging a sealing module assembly in an opening in a structure, which sealing module comprises peelable layers at its outer circumference, a radial inner layer having a greater extent in an axial direction than a radially outer peelable layer the steps of: inserting the modular assembly into the opening until it is obstructed by a peelable layer, removing the peelable layer which prevented the insertion and any peelable layers radially outside it. This corresponds to a method of using the above device according to the second alternative.
The present invention also relates to a sealing system comprising cable passages or pipe penetrations receiving one or more compressible modules surrounding each cable or pipe, which cable passages or pipe penetrations are placed directly in an opening in a wall or another structural divider forming a wall, the compressible module being a module according to the general description above or the detailed description that follows.

Fig. 8 is a perspective view of a module according to the present invention.
Fig. 9 is a perspective view of a part of the module according to ﬁ g. 8.
Fig. 10 is a perspective view of a further module or seal according to the present invention.
Fig. 11 is a perspective view of a part of the module according to Figs. Detailed Description of Embodiments The Compressible Module 100 in ﬁ g. 1-4 comprise two base portions 102 and 104, both of which have semicircular grooves which together define a circular through hole. In the through hole, peelable material layers 106, 108 are arranged. In the middle of the circular through hole a blind part 110 is arranged. One reason for using a blind part is that there is no reason to stack peelable layers in a volume that will be occupied by a cable at a later stage. I ﬁ g. 1, the peelable layers 106, 108 have an air gap between adjacent layers, but this is for illustrative purposes only. In a practical case, adjacent layers are in contact and in most cases bonded together by adhesion.
The layers can be arranged in different ways and with different properties, which is reflected in the simultaneously submitted applications called (A Pipe or Cable Lead-Through having Interconnected Layers, "A Pipe or Cable Lead-Through having Layers of Different Thickness", "A Pipe or Cable Lead-Through having a Part Indicating Compression "," Cohering Between layers of a Pipe or Cable Lead-Through "and" Identification of Layers of a Pipe or Cable Lead-Through "submitted by the applicant for the present application. These applications are hereby incorporated by reference. as references.
In this first embodiment, each radially outer layer has a longer extent in an axial direction than a radial inner layer, and all layers are flush at a lateral end thereof. This results in the formation of a step-like appearance, which is clearly shown by ﬁ g. 1-4. In other embodiments, the step-like appearance may be present at both lateral ends of the layers. "Radial exterior" refers to a relative position relative to the center of the compressible module in a composite state.
In use, set the compressible module 100 to ﬁ g. 1 together, after which a cable 112 is inserted, concentric with the amount of peelable material layers, as shown in ﬁ g. For obvious reasons, it is only possible to insert the cable 112 for a limited distance before it is obstructed by a pair of layers 106, 108. In this position, the two base parts can be taken apart and the correct number of layers easily removed, as shown in Figs. 3.
By not removing the cable 112 when the base members are disassembled, it is easily determined how many layers must be removed, simply by observing how far into the cable extends into the base member.
In Fig. 4, the cable 112 has been positioned in the compressible module, and the compressible module has been compressed to provide a sufficient seal.
Alternative embodiments of the modules appear from the co-pending applications entitled "Eccentric Part of a Pipe or Cable Lead-Through" A 10 15 20 25 30 35 Module of a Pipe or Cable Lead-Through having Grooves on Opposite Sides "," Pipe or Cable Lead-Through Blocks ”,“ A Pipe or Cable Lead-Through having Modularized Modules ”and“ A Pipe or Cable Lead-Through having Layers of Alternating Geometry ”, submitted by the applicant for the present application. According to one embodiment, the modules are divided from a set of stapled module halves, as described in the co-pending application entitled "Modules of Pipe or Cable Lead-Through Sticking Together", taught by the applicant for the present application. These applications are hereby incorporated by reference.
If a number of identical cables 112 are to be arranged, it is very easy to remove a correct number of layers simply by knowing how far the cable extends into the module. It is obvious from ﬁ g. 1-4 that a portion of each layer may be visible, and extend beyond superimposed layers. In one or more embodiments, these portions may be provided with an identification mark related to cable diameter, successive numbers, color codes, etc., which further simplifies for the user to remove the correct number of layers.
According to another embodiment (not shown), only the scalable layers of a module half have a step shape. In this embodiment, the base parts should of course not be assembled before determining how many layers should be removed.
Fig. 5 shows a sealing system in which a number of compressible modules have been positioned in a frame 114, and a compression unit 116 has been used to compress the modules. In this context, it should be mentioned that there are ﬂ your different types (in terms of shape, design, function) of compression units and frames, and the present invention should not be limited to a particular type of compression unit or frame.
An alternative system comprising a framework is described in a co-pending application called "Sealing System", submitted by the applicant for the present application.
This application is hereby incorporated by reference.
F ig. 6 is a flow chart of an embodiment of the inventive method for adjusting the inner diameter of a compressible module with peelable layers, which has been described above with reference to. G. 1-4.
Fig. 7 shows another aspect of the invention. By adapting the dimensions of a compressible module, or a system comprising compressible modules, to the dimensions of an opening in a divider 220, this can be achieved by means of peelable layers 206, 208 arranged on the outer diameter of the compressible module or system comprising compressible modules 200. The modules 200 shown comprise two base portions 202, 204, a blind portion 210 and peelable layers on both the inside and outside of each base portion. The function is easy to understand; by peeling layers 206, 208, the diameter of the assembly can be changed. The inventive aspect of ﬁ g. 7 is that trial-and-error can be avoided by simply inserting the unit into the opening and removing layers that do not enter the opening. The assembly according to this second aspect of the invention may optionally be provided with peelable layers according to the first aspect of the invention. When the compressible module 200 is compressed, it will expand in all directions, thereby compressing existing cables or additional modules arranged in its central opening, and also secured in the opening 220 of the divider by an outward expansion. It should be noted that the cross section of the unit may have any suitable shape designed according to the shape of the opening. A circular or rectangular cross section may be the most common. The basis for this type of system has been described earlier in the application.
The module 300 of the embodiment according to ﬁ g. 8 and 9 comprise two base parts 302, 304. On the inside of each base part 302, 304 a number of peelable layers or sheets 306 are arranged in a semicircular groove. The layers 304 are at iron height at one end of the base portion 302, 304, while at the other end the layer adjacent the base portion 302, 304 has the longest extension in the axial direction. Each subsequent layer is slightly shorter than the underlying layer, resulting in a step-like appearance.
The module 400 according to Figs. 10 and 11 is a cylindrical seal which is often arranged in an opening in a wall or other divider. The module 400 comprises two base parts 402, 404.
On the inside of each base part 402, 404, a number of peelable layers or sheets 306 are arranged in a semicircular groove. Here, too, the layers 406 have a step-like appearance at one end, with the longest layer closest to the base portion 404. Although not shown herein, those skilled in the art will appreciate that the module may have a number of peelable layers on the outside, in the same manner as in Fig. 7. on the outside is peeled off to adapt the module to an opening that will receive the module.
Two embodiment branches form part of the same idea of invention, but according to one branch the radially inner layers have an extension in the axial direction which exceeds the radially outer layers, and according to the other branch this relationship is reversed. For both branches, however, a peelable layer closer to the compressible module has a longer extent in a radial direction than a peelable layer further away from the compressible module.
According to a further embodiment, the seal, passage or bushing according to the present invention is provided with means for Lubrication as shown in the co-pending application "Lubrication of a Pipe or Cable Lead-Through" submitted by the applicant for the present application. This application is hereby incorporated by reference.
