Definitions

  • the present invention relates to a filling element for cable transit modules of cable transit systems intended to be mounted on a wall to allow cables or tubes, in particular electric cables, to pass through the wall itself .
  • the cable transit systems used today are, in fact, very useful during the implementation of electric or hydraulic systems in structures such as ships or aeroplanes in which there are no walls where it is possible to integrate ducts for the passage of cables but only walls that separate the different environments and that must be passed through by the cables.
  • These cable transit systems are, in particular, arranged to ensure a sealed passage of liquids, gases or other particles.
  • the cable transit systems comprise a supporting frame which is inserted into a wall in such a way as to delimit an opening, and a plurality of cable transit modules which are arranged inside the supporting frame in side by side and/or overlapped rows .
  • One or more metal compression plates coupled to the supporting frame can be provided in such a way as to define a plurality of housing spaces for the cable transit modules in the opening.
  • cable transit modules are made of bodies of elastically compressible material which have a duct intended to be crossed by a cable or a tube.
  • the compressible bodies of the cable transit modules are typically composed of two half-shells which have two respective semi-cylindrical seats or cradles which, when the module is assembled, form the duct for the passage of the cable or tube.
  • Each half-shell can have on its semi-cylindrical seat a stack of removable concentric semi-cylindrical layers, of a thickness of about 1 mm, which allows to adapt the diameter of the duct to the diameter of the cable or tube .
  • the seal against gases, liquids or particles of the ducts is obtained by appropriately compressing the modules themselves packed into the frame, so that the ducts are enclosed and compressed sealingly around the cables that pass through them.
  • filling elements are inserted in the ducts or cylindrical seats of the cable transit modules not crossed by the cables or tubes, which act like real caps.
  • These filling elements have a shape which is complementary to that of the duct, typically cylindrical, and have a rubber body of high hardness, for example about 90 shore A.
  • Water leakage may occur at the duct of a cable transit module if a filling element is inserted into this duct. These losses are very rare and tend to occur above all at pressures higher than 3-4 bar due to the imperfect sealing of the interface between the internal walls of the duct and the external surface of the filling element housed in the duct itself. In fact, at high pressures, the filling element which is typically made of rubber can deform and cause an improper seal of the duct .
  • the object of the present invention is to obviate the aforementioned drawbacks, and in particular that of devising a filling element for cable transit modules which allows to improve the seal against liquids in the duct of the cable transit modules.
  • FIG. 1 is a sectional view along a longitudinal plane of a first embodiment of a filling element according to the present invention
  • FIG. 2 is a sectional view along a longitudinal plane of a second embodiment of a filling element according to the present invention
  • FIG. 3 is a perspective view of a cable transit module provided with a filling element whose assembly is complete.
  • a filling element or plug for cable transit modules is shown, indicated comprehensively with number 10.
  • This filling element 10 is intended to be inserted in a duct of a cable transit module 20 in such a way as to obstruct it.
  • the cable transit module 20 comprises two half-shells 21, 21' of elastically compressible material which have two respective semi-cylindrical seats which form a cylindrical seat or duct for the passage of a cable or tube or the filling element 10 by uxtaposition of the two half-shells 21, 21'.
  • the half-shells 21, 21' have an external square profile so as to be able to be firmly supported on a flat surface.
  • the cable transit module 20 is therefore preferably made in the form of a parallelepiped.
  • each half-shell 21, 21' can have a stack of removable concentric semi-cylindrical layers 22, 22' coupled to the respective semi-cylindrical seat such that the diameter of the duct depends on the number of said removable semi-cylindrical layers present 22, 22' on the cradles of the two half-shells 21, 21'.
  • the filling element 10 is inserted into the cable transit modules 20 which, upon installation, are not intended to be crossed by cables in order to ensure the seal of these modules against gases, liquids or particles.
  • the filling element 10 must therefore be able to occlude the duct where it is inserted.
  • the filling element 10 comprises a rubber body 11 which extends along a longitudinal direction X.
  • this rubber body 11 is cylindrical in shape and has a circular section of a diameter substantially equal to that of the duct of the cable transit module wherein the filling element 10 must be inserted such to guarantee its seal against gases, liquids or particles.
  • the longitudinal length of the rubber body 11 is substantially equal to that of the duct.
  • the rubber body 11 can have a section of any shape which is complementary to that of the section of the duct in which it is intended to be inserted, for example prismatic .
  • the rubber body 11 is made of EPDM rubber (Ethylene-Propylene Diene Monomer) .
  • the filling element 10 comprises a substantially rigid armour 12 embedded inside the rubber body 11 which extends for a portion of the longitudinal length of the rubber body 11 such that two end portions 13 of the rubber body 11 are without armour.
  • the armour 12 can be of hollow tubular shape, as in the embodiment shown in figure 1, above all in the case of filling elements with a diameter greater than or equal to about 10 mm.
  • the armour 12 can have a solid cylindrical body, as in the embodiment shown in figure 2, above all in the case of filling elements with a diameter of less than about 10 mm, for example about 6 mm.
  • substantially rigid armour is intended to indicate an armour which, when subjected to the pressures to which the filling elements can be subjected once inserted into the respective cable transit modules, has a negligible deformation with respect to that of a filling element constituted by a rubber body.
  • a substantially rigid armour 12 can have a deformation of less than one-tenth of a millimetre at a pressure of 4-6 bars.
  • the armour embedded inside the rubber body is intended as a body completely contained in the rubber body 12 and which does not have any portion facing outside the rubber body 12, as can be seen in figures 1 and 2.
  • the two end portions 13 are not armoured and, therefore, maintain a certain flexibility with respect to the armoured portion which, instead, is more rigid. These end portions are necessary in order to longitudinally guarantee the thermal and electrical insulation of the filling element 10.
  • the armour 12 is made of metallic material, for example MILD STEEL IS 2062, or common iron.
  • the armature 12 is made of glass fibre.
  • the armour 12 consists of micalite.
  • the armour 12 confers stiffness to the rubber body 11 such that the filling element 10 does not deform or in any case have a radial deformation, for example less than one tenth of a millimetre, when the respective cable transit module 20 is subjected to operating pressures or even at pressures higher than 4-6 bar.
  • the portion of the rubber body 11 covering the armour 12 must be less thick as possible to ensure high rigidity.
  • the portion of the rubber body 11 covering the armour 12 has a thickness S comprised between about 1 mm and 2 mm.
  • the filling element has greater rigidity with respect to the rubber, while maintaining low costs related to thermal and electrical insulation.
  • the greater rigidity of the filling element hinders the deformation of the same at high pressures, thereby naturally favouring the seal of the duct.
  • the thermal and electrical insulation is maintained thanks to the rubber body enclosing the armour, which gives rigidity to the tubular filling element.
  • the ends of the rubber body are not armoured and, therefore, create a real barrier against the transmission of heat and electricity.
