Modular bulkhead for sealing passage of cables and pipes in structures of all kinds

Abstract

A sealed feedthrough or bulkhead for cables or pipes in a wall assembled from modules having block-shaped members defining spaces in which a test pressure can be applied, utilizes spacers between the block-shaped members which maintain gaps between them while having pins extending into the block-shaped members.

I claim:  
     
         1 . A module capable of assembly with similar modules to form a feedthrough for sealed passage of a cable or pipe traversing a wall, comprising: 
 two block-shaped members spaced apart longitudinally in a direction of passage and formed with respective arc-segmental recesses; and    at least one spacer between said members and securing said members together.    
     
     
         2 . The module defined in  claim 1  wherein each of said arc-segmental recesses is semicylindrical.  
     
     
         3 . The module defined in  claim 2  wherein said spacer is configured to maintain a gap between said block-shaped members for receiving a pressurized fluid for testing a seal formed by the feedthrough upon assembly of two of said modules.  
     
     
         4 . The module defined in  claim 3  wherein said block-shaped members have openings adjacent outer edges thereof into  
     
     
         5 . The module defined in  claim 3  wherein said spacer has a pin received in said block-shaped members and an annular flange disposed midway along said pin and spacing said members apart.  
     
     
         6 . The module defined in  claim 3  wherein said spacer comprises a pin received in said block-shaped members and a ring on said pin spacing said members apart.  
     
     
         7 . The module defined in  claim 3  wherein said spacer is a frame segment formed with a plurality of pins received in recesses formed in juxtaposed ends of said block-shaped members.  
     
     
         8 . The module defined in  claim 7  wherein said spacer has four of said pins in pairs on opposite sides thereof, each pair of said pins extending into a respective one of said block-shaped members.  
     
     
         9 . The module defined in  claim 8 , further comprising at least one channel formed in said spacer for admitting said fluid to said gap.  
     
     
         10 . The module defined in  claim 9  wherein said frame segment has outer dimensions less than outer dimensions of said block-shaped members.  
     
     
         11 . The module defined in  claim 9  wherein said frame segment has a semicylindrical recess of greater radius of curvature that the semicylindrical recesses of said block-shaped members.  
     
     
         12 . A modular feedthrough for sealed passage of a cable or pipe traversing a wall, comprising: 
 two feedthrough modules each comprised of: 
 two block-shaped members spaced apart longitudinally in a direction of passage and formed with respective semicylindrical recesses, and  
 at least one spacer between said members and securing said members together, whereby  
   upon juxtaposition of said feedthrough modules, said semicylindrical recesses form cylindrical passages sealing receiving said cable or said pipe of a solid body, and said spacers maintain gaps between said block-shaped members for receiving a pressurized fluid for testing a seal formed by the feedthrough the juxtaposition of the two modules.    
     
     
         13 . The modular feedthrough defined in  claim 12  wherein said block-shaped members have openings adjacent outer edges thereof into which pins of the respective said spacer extend.  
     
     
         14 . The modular feedthrough defined in  claim 12  wherein each said spacer has a pin received in the respective block-shaped members and an annular flange disposed midway along the respective pin and spacing the respective said members apart.  
     
     
         15 . The modular feedthrough defined in  claim 12  wherein each said spacer comprises a pin received in the respective said block-shaped members and a ring on the respective pin spacing the respective said members apart.  
     
     
         16 . The modular feedthrough defined in  claim 12  wherein each said spacer is a frame segment formed with a plurality of pins received in recesses formed in juxtaposed ends of the respective block-shaped members.  
     
     
         17 . The modular feedthrough defined in  claim 16  wherein each said spacer has four of said pins in pairs on opposite sides thereof, each pair of said pins extending into a respective one of said block-shaped members.  
     
     
         18 . The modular feedthrough defined in  claim 17 , further comprising at least one channel formed in each spacer for admitting said fluid to said gaps.  
     
     
         19 . The modular feedthrough defined in  claim 18  wherein each said frame segment has outer dimensions less than outer dimensions of said block-shaped members.  
     
     
         20 . The modular feedthrough defined in  claim 18  wherein each said frame segment has a semicylindrical recess of greater radius of curvature that the semicylindrical recesses of the respective said block-shaped members.
