Anti-vibration and shock pressure relief device for compound containers

Abstract

The present invention discloses a anti-vibration and shock pressure relief device for compound containers, which is installed in one face of a container, and which comprises a sealing board and a pressure relief module. The sealing board is installed in the abovementioned face of the container and having at least one through-hole where the pressure relief module passes through the sealing board. The pressure relief module includes a top cover having at least one exhaust hole and a fastening member passing through the sealing board; an engagement member installed inside the top cover and having a pressure relief valve thereinside. The pressure relief device applies to various compound containers and can timely release the vaporized gas accumulated inside the container. Thereby, the present invention can effectively prevent compound containers from explosion and obviously improve the safety of compound containers.

What is claimed is: 
     
         1 . A anti-vibration and shock pressure relief device for compound containers, which is installed in one face of a container, and which comprises
 a sealing board installed in said face of said container and having at least one through-hole;   a pressure relief module installed in said through-hole and including a top cover having at least one exhaust hole and a fastening member passing through said sealing board; and   an engagement member installed inside said top cover and having a pressure relief valve thereinside.   
     
     
         2 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1  further comprising an annular locking member installed inside said fastening member of said top cover and securing said pressure relief module to said sealing board. 
     
     
         3 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein said engagement member is made of rubber. 
     
     
         4 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein said top cover is made of a metallic material. 
     
     
         5 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein said engagement member has a channel there inside , and wherein gas flows to said exhaust hole of said top cover via said channel. 
     
     
         6 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein each of said pressure relief valve and said sealing board is made of a metallic material. 
     
     
         7 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein said pressure relief valve has an annular trench on a surface thereof. 
     
     
         8 . The anti-vibration and shock pressure relief device for compound containers according to  claim 7 , wherein said annular trench is fabricated to have a circular shape, a C-like shape, a polygonal shape or an irregular shape. 
     
     
         9 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein said sealing board is joined with said container with a laser welding technology or an ultrasonic welding technology. 
     
     
         10 . The anti-vibration and shock pressure relief device for compound containers according to  claim 1 , wherein said pressure relief module is joined with said sealing board with a welding technology.
