Definitions

  • the present invention relates to a bulkhead for the sealed passage of cables and pipes for structures or all kinds, for example, equipment, building structures, ship walls, aircraft partitions. More particularly, the invention relates to a modular penetration seal for the sealed passage of cables and pipes and which enables detection of the tightness of the seal formed by the unit.
  • Modular units allowing the sealed passage of cables and pipes and utilizing components which have two block shaped parts, each of which has a semicylindrical recess and which sealingly engage a cable, a pipe or a filler body when pressed together against the latter and fully surround the member against which those parts are engaged, are known from EP 0 429 916 B1.
  • Such modules can be stacked alongside one another and over one another, e.g. in layers. They can be received in a frame in a wall, roof structure or other structural element and by selection of the number of modules and their dimensions, a grid of cable or pipe passages can be provided and, depending upon the dimensions, cables, pipes or filler members of different diameters can be sealed.
  • the filler bodies can be removed where required and replaced by cables or pipes.
  • anchor plates or gaskets can be provided which can be secured against the frame and thus prevent sliding of the modules out of the frame.
  • the modules can be clamped in the frame by wedge assemblies which apply a pressure to the modules to press the modules together and against the frame so that the entire assembly of frame, modules, wedge members, anchor plates and gaskets is sealed against the passage of water, fire and gas.
  • Round gland-type frames can also be used which can be inserted into a core bore and by means of which the requisite pressure for sealing action can be generated by the tightening of drawbolts or the like.
  • double bulkhead systems have been developed in which two identical penetration seals were provided, one following the other in a frame dimensioned to be correspondingly larger and adapted to be set in the wall.
  • a space was provided between the two bulkheads and that space was supplied with compressed air or a test gas and the measurement of the pressure drop in that space with time was determined.
  • Leaks from the system could be ascertained by leak testing sprays or the like.
  • a double seal of that type was also uneconomical since it at least doubled the cost of a penetration seal arrangement.
  • the double bulkhead approach therefore, was only used in highly explosive environments, in some specialized locations or as fire prevention in extremely sensitive environments in which the added expense was justified.
  • a seal module having two block-shaped parts each formed with a semicylindrical recess and into which selectively a member selected from a cable, a pipe and a filler body can extend in a longitudinal direction and can be sealingly engaged, each module having external sealing surfaces formed with grooves transverse to the longitudinal direction, at least one bore being formed in the module in at least one of the grooves and reaching into the module to an outer surface of the member.
  • two bores are provided so that the grooves in each sealing surface can be provided with a respective such bore.
  • the network of grooves and bores within the bulkhead provides the requisite test space and can be pressurized by a compressor and can have the pressure monitored over time so that leakage can be determined and a filler of the seal connected.
  • a method of providing a penetration seal in the form of the gas tight bulkhead comprises:
  • FIG. 1 Is a perspective view of a modular penetration seal for the sealed passage of pipes through a structure, illustrated somewhat diagrammatically;
  • FIG. 2 is a perspective view of two partial pieces of the module of FIG. 1 showing a filler body adapted to be sealed therein;
  • FIG. 3 is a vertical section through a modular penetration seal in which the modules are received in a frame
  • FIG. 4 is a perspective view of a wedge seal for use with the modules of the invention.
  • FIG. 5 is a vertical section through a modular penetration seal with a gland frame construction.
  • FIGS. 1 to 3 A modular penetration seal for the sealed passage of cables and pipes through structure in which the seal is to form a gas tight bulkhead is shown in FIGS. 1 to 3 and permits cables and pipes represented generally at 1 to pass through a wall 2 in a structure which can be a building, an apparatus, a ship or some other barrier between two parts for which a gas tight (and liquid tight) seal is required between the parts.
  • the modules 3 which are used for this purpose according to the invention each comprise two block-shaped parts 4 (compare FIGS. 1 and 2), with each of the parts being generally of the shape of a rectangular parallepiped so that when the parts 4 are assembled together, the module seen in FIG. 1 has also the shape of a rectangular parallelepiped.
  • the block shaped parts 4 are provided with semicylindrical recesses into which selectively a member which can be a cable, a pipe or a filler body can be sealingly engaged.
  • the cable or pipe has been represented at 1 and the filler body at 6 in the drawing.
  • the recesses 5 can be lined with rubber, e.g. a single rubber body or rubber laminations or rubber laminated with other materials to form a compressible seal durably gripping the cable or pipe 1 or the filler body 6 .
  • Each module 3 has external sealing surfaces 7 , 8 which lie in mutually perpendicular planes and delimit the rectangular paralalia piped parallel to the cable or pipe 1 and the axis of the filler body 6 .
  • Two sealing surfaces 8 are vertical surfaces as shown in FIG. 1 and are parallel to one another but perpendicular to the horizontal sealing surfaces 7 shown in this figure.
  • grooves 9 which open outwardly.
  • the grooves 9 have stretches running through each of the surfaces 7 , 8 mentioned previously and in at least one of the grooves 9 a bore 10 is provided which extends perpendicular to the axis of the cable or pipe 1 or the filler body 6 and thus to the axis of the recesses 5 in which that member is received.
  • the bore 10 extends into the module 3 from the base of the groove 9 to the outer surface 11 of the cable or tube 1 or the filler body 6 .
  • the grooves 9 are preferably 2 mm deep rectangular millings in the surfaces 7 , 8 which adjoin another so as to extend around the entire perimeter.
  • the width of the grooves can vary and in general will be equal to or greater than the diameter of the bore 10 which opens at the base of the groove.
  • the bores 10 have preferably diameters of 8 mm.
  • the modules 3 are inserted into a frame 12 (FIG. 3) which in turn is received in an opening 13 in the wall 2 .
  • a respective anchoring gasket 14 is provided which has a throughgoing opening 15 at the adjoining regions of the grooves 9 .
  • the anchor gaskets 14 prevent sliding of the modules 3 one another together at the frame 12 .
  • the sides of the anchor gaskets 14 can additionally be stamped with triangular formations.
  • the communicating system is a network of horizontal and vertical passages which is closed toward the spaces on opposite sides of the wall 2 and forms a network wholly within the frame in which a test gas volume can be provided for the bulkhead formed by the module assembly.
  • Passages 16 can be provided to communicate with or form part of this network in the wedge unit 18 securing the frame and modules together and which can bear upon the upper frame member 19 and the upper surface of the top row of modules.
  • the passages 16 can likewise be formed in grooves 9 of the wedge unit 18 .
  • the wedge unit 18 can comprise upper and lower beams 18 a and 18 b whose upper and lower surfaces are placed against the surface 19 and the upper row of modules, respectively, and which are wedge shaped but sealed together along the exteriors at 18 c and 18 d .
  • Spindles 18 e traversing wedge blocks 18 f and 18 g press these wedge blocks together upon the tightening of the spindles in respective nuts to spread the beams 18 a and 18 b apart and clamp the module assemblies 3 in the frame 12 .
  • a compressed air coupling 20 can be connected to the passage network within the penetration seal or bulkhead and pressure loss after pressurization can be measured by a manometer 20 a , for example, to signal the integrity of the seal or bulk.
  • a manometer 20 a for example, to signal the integrity of the seal or bulk.
  • FIG. 5 there is shown an alternative bulkhead-type modular penetration seal in which a round gland-type frame 21 is formed in a circular opening 13 ′ in the wall 2 ′ and in which the modules 3 can be clamped sealingly.
  • the network of passages 9 , 10 , etc. can be pressurized through the compressed air coupling 20 and the pressure loss indicated by the manometer 20 a .
  • the compressed air source is represented by the compressor 20 b in FIG. 5.
  • a test pressure of about 4 bar can be provided in the passage network and the pressure drop determined by the manometer.
  • the location of the leak can be determined by conventional bubble forming methods by leak testing sprays or the like, thereby indicating whether one side or both sides of the module are not tight.
  • the penetration seal can be remounted to see if the failure can be remedied. Otherwise a replacement module 3 can be provided.
  • the module 3 can be tested for fabrication failures.
