  • seal Another type of seal, cable transition, pipe penetration etc. has a general cylindrical form and is to be received in a sleeve in a wall or an opening in a wall. To func- tion in the desired way the seal should fit snugly into the sleeve or the opening of the wall in which it is received and the seal should be adaptable to the actual mounting dimension.
  • the mounting dimension is dictated by the inner diameter of the sleeve or the opening.
  • the seal has a cylindrical compressible body, which is compressed axially between fittings at the opposite ends of the compressible body. By the axial compres- sion the cylindrical body will expand radially both inwards and outwards. When doing so, any compressible modules arranged in the compressible body will be compressed as well, and thus sealing will be effected.
  • the pipes, wires or cables received may have different outer diameters, and, thus, the module should be adaptable to cables or pipes having different outer diameters.
  • Seals or transitions of both the above kinds are used for sealing in many different environments, such as for cabinets, technical shelters, junction boxes and machines. They are used in different industrial environments, such as automotive, telecom, power generation and distribution, as well as marine and offshore.
  • the seals or transitions may have to seal against fluid, gas, fire, rodents, termites, dust, moisture etc., and may receive cables or wires for electricity, communication, computers etc., pipes for different gases or liquids such as water, compressed air, hydraulic fluid and cooking gas or wires for load retention.
  • the parts receiving a single cable etc. of both the types discussed above often have a pack of peelable layers or sheets on the inside.
  • the layers or sheets are peeled off until the inner diameter of the part is adapted to the outer diameter of the cable received in said part.
  • the sheets adhere strong enough to each other to stay together and at the same time loose enough to enable the sheets to be peeled off from the stack, either one- by-one or a number of sheets together.
  • the pack of layers may have another cross sectional form than circular.
  • the present invention aims at providing a compressible module, which is im- proved in certain aspects in relation to prior art, in particular relating to installation time and sealing properties.
  • the present invention achieves the inventive objects by the provision of a base part for a compressible module for cable entries or pipe penetrations receiving one or more compressible modules surrounding each cable or pipe, which cable entries or pipe penetrations are placed either directly in an opening through a wall or other structural partition forming the wall or other partition or in a frame, whereby a barrier is formed of the one or more modules and at least one compression unit in either the opening or the frame, wherein the compressible module has at least one peelable layer for adapting to the diameter of a cable or pipe, which at least one peelable layer is placed in a base part, wherein each base part has several grooves, receiving at least one peelable layer.
  • the inventive module is characterized in that the grooves are arranged on opposing sides of the module.

  • the base part has two or more grooves for peelable layers placed side by side on one side and one or more grooves for peelable layers placed on the opposite side, and according to one modification thereof the number of grooves on one side of the base part exceeds the number of grooves on the opposite side by one. This gives the possibility of even greater space efficiency, since a groove on the one side may be arranged between two grooves on the opposite side. This will be more easily understood when studying the detailed description.

  • a common type of seals or transitions for cables and/or pipes is indicated in Fig. 1. It has an outer frame 1 received in a wall or any other type of partition. Inside the frame 1 a number of modules 2 are arranged to receive a single cable or pipe each. Furthermore, a compression unit 3 is received inside the frame 1. The modules 2 are sepa- rated by stay plates 4, which stay plates 4 are arranged to position the modules 2 safely inside the frame 1. The stay plates 4 have beeds in the width direction, which keeps the modules localized in the axial direction, or depth direction. The modules 2 are compressible parts 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 including a frame is described in the simultaneously filed application entitled “Sealing System", filed by the applicant of the present application. This application is hereby incorporated by reference.
  • a module half is shown, which corresponds with the modules 2 of Fig. 1.
  • the module half has a base part 6 with a generally rectangular appearance, having a semi cylindrical groove at one side. Inside the semi cylindrical groove of the base part 6 a number of peelable sheets 7 are received. In use two module halves are put together with the grooves facing each other. The module thus formed will have a central cylindrical opening, in which a cable or pipe is to be received.
  • the sheets may be arranged in many different ways and with different features as reflected in the simultaneously filed applications entitled “A Pipe or Cable Lead- Through having Interconnected Layers”, “A Pipe or Cable Lead-Through having Layers of Different Thickness”, “Cohering Between Layers of a Pipe or Cable Lead-Through” and “Identification of Layers of a Pipe or Cable Lead-Through”, filed by the applicant of the present application. These applications are hereby incorporated by reference.

  • the high flexibility has its benefits, yet regarding e.g. assembly time and space efficiency there are improvements to be made.
  • FIG. 3 illustrates compressible modules according to a first embodiment of the present invention.
  • the base part 8 in the middle has one half cylindrical groove on each of two opposing sides. In said cylindrical grooves one or more peelable layers or sheets 9 are placed.
  • the module of Fig. 4, or rather one base part 106 thereof is characterized in that several recesses or grooves 110 are arranged in each base part 106. Peelable sheets 107 are arranged in each groove 110.
  • the grooves 110 are arranged "back-to-back", on opposite sides of the module, as compared to known modules where the groove is arranged on one side of the module only. This gives the advantage of reducing the number of compressible modules 102 needed in an installation, which also reduces the number of surfaces to seal, the number of modules to be aligned, and thus the installation or assembly time.
  • the amount of material may be reduced between adjacent grooves, in the horizontal direction (or width direction) as well as in the vertical direction, with maintained rigidity as compared to a system of the type illustrated in Fig. 1.
  • a base part 206 thereof is illustrated in Fig. 5.
  • the base part is designed to cover an entire row of a frame. This reduces the number of modules even further.
  • This design also enables the removal of the above mentioned stay plates 4 since the base parts may be designed to cooperate with the frame. This design simplifies the assembly even further, for obvious reasons.
  • One less obvious result is that it also simplifies horizontal installations, e.g., when the seals or transitions are arranged in a ceiling or floor. In such cases the cooperation between base parts and the frame reduces the risk of modules falling out of the frame during installation.
  • the lowermost and the uppermost base part, or any base part abutting a stay plate should be a base part of more conventional design. This is illustrated in Fig. 6, where the lowermost base part is a "module half 6 of a conventional design. However, even in the worst case, where two conventional base parts sandwiches one inventive base part, the total number of individual pieces will be three instead of four, which is an improvement.
  • Stay plates are generally used to improve stability and load distribution in a sealing system. The present system may be used in combination with stay plates. It may also, however, be used without stay plates, and in this use it has advantages as compared to prior art systems, since the number of sealing surfaces will be reduced.
  • the compressible module 306 of Fig. 7 has a larger number of grooves on the lower side than on the upper. This has the beneficial effect of making the module even more space efficient, since the shape of the grooves may be matched for this purpose. For this reason it is presently considered appropriate that the number of grooves on one side exceeds the number of grooves on the other by one. In the embodiment shown, the dimension of the grooves on the one side is smaller than the dimension of the grooves of the other side.

  • Such a base part having a hinge may be placed either as end parts or middle parts, depending of the mutual positions of the two hinged parts of the base part. If the two parts are placed side-by- side the base part is an end part and if the two parts are placed on top of each other the base part is a middle part.
