Abstract

A vacuum relief assembly for a containment vessel. The vacuum relief assembly includes a normally closed pressure activated valve assembly that selectively permits flow into the containment vessel from the atmosphere through an interior passage. The valve body includes inlet opening into the interior passage. It also includes a torque acceptance portion to permit connection of the valve assembly to a vessel. A tamper resistant cap is secured in overlying relation to the inlet opening and the torque acceptance portion. The cap is secured with mechanism that provides indicia of tampering.

Claims

exact text as granted — not AI-modified
1 . A vacuum relief assembly for a containment vessel comprising:
 a valve body having an interior wall defining a passage including an inlet opening and an outlet opening, said outlet opening being adapted for fluid communication with a containment portion of a containment vessel and said inlet opening being open to atmosphere, a normally closed valve, closing said passage and operable to selectively open said passage between said inlet opening and said outlet opening,   a cap mounted on said valve body, said cap overlying said inlet opening in spaced relation to said valve body, said cap configured to prohibit access to said passage through said inlet opening.   
     
     
         2 . A vacuum relief assembly as claimed in  claim 1 , wherein said valve body is generally cylindrical and includes a securement end portion configured to be secured to a containment vessel and wherein said cap and said valve body define a space between said valve body and said cap providing a flow path between said inlet opening and an outside atmosphere. 
     
     
         3 . A vacuum relief assembly as claimed in  claim 2 , wherein said valve body includes a generally cylindrical upper sidewall having an upper edge surface portion and at least one mounting post projecting upwardly from said upper edge surface of said sidewall portion, arcuate spaces defined by said upper edge surface and said at least one mounting post defining said inlet opening. 
     
     
         4 . A vacuum relief assembly as claimed in  claim 3 , wherein said cap is secured to said at least one mounting post. 
     
     
         5 . A vacuum relief assembly as claimed in  claim 4  wherein said valve body includes a plurality of mounting posts projecting upward from said upper edge surface of said sidewall portion, said arcuate spaces defined by said upper edge surface and said mounting posts, and wherein said cap includes a top wall defining an interior surface supported on said mounting posts and a generally cylindrical side wall surrounding said inlet opening and said generally cylindrical upper wall portion in spaced relation thereto. 
     
     
         6 . A vacuum relief assembly as claimed in  claim 3 , wherein said valve body includes a torque acceptance configuration and said cap surrounds said torque-acceptance configuration prohibiting access thereto. 
     
     
         7 . A vacuum relief assembly as claimed in  claim 4  wherein said valve body includes a torque-acceptance configuration and said cap surrounds said torque-acceptance configuration prohibiting access thereto. 
     
     
         8 . A vacuum relief assembly as claimed in  claim 5  wherein said valve body includes a torque-acceptance configuration and said cap surrounds said torque-acceptance configuration prohibiting access thereto. 
     
     
         9 . A vacuum relief assembly as claimed in  claim 6 , wherein said valve body includes a shoulder surface extending radially outwardly from said valve body above said torque acceptance configuration and said generally cylindrical upper wall portion of said valve body extends upwardly from said shoulder surface. 
     
     
         10 . A vacuum relief assembly as claimed in  claim 8 , wherein said valve body includes a shoulder surface extending radially outwardly from said valve body above said torque acceptance configuration and said generally cylindrical upper wall portion of said valve body extends upwardly from said shoulder surface. 
     
     
         11 . A vacuum relief assembly as claimed in  claim 6  wherein said torque-acceptance configuration is a hexagonally shaped flange. 
     
     
         12 . A vacuum relief assembly as claimed in  claim 7  wherein said torque-acceptance configuration is a hexagonally shaped flange. 
     
     
         13 . A vacuum relief assembly as claimed in  claim 8  wherein said torque-acceptance configuration is a hexagonally shaped flange. 
     
     
         14 . A vacuum relief assembly as claimed in  claim 9  wherein said torque-acceptance configuration is a hexagonally shaped flange. 
     
     
         15 . A vacuum relief assembly as claimed in  claim 10  wherein said torque-acceptance configuration is a hexagonally shaped flange. 
     
     
         16 . A vacuum relief assembly as claimed in  claim 4  wherein said cap is secured to said at least one mounting post by at least one fastener member. 
     
     
         17 . A vacuum relief assembly as claimed in  claim 7  wherein said cap is secured to said at least one mounting post by at least one fastener member. 
     
     
         18 . A vacuum relief assembly as claimed in  claim 9  wherein said cap is secured to said at least one mounting post by at least one fastener member. 
     
     
         19 . A vacuum relief assembly as claimed in  claim 5  wherein said cap is secured to each said mounting post by a fastener member. 
     
     
         20 . A vacuum relief assembly as claimed in  claim 8  wherein said cap is secured to each said mounting post by a fastener member. 
     
     
         21 . A vacuum relief assembly as claimed in  claim 10  wherein said cap is secured to each said mounting post by a fastener member. 
     
     
         22 . A vacuum relief assembly as claimed in  claim 13  wherein said cap is secured to each said mounting post by a fastener member. 
     
     
         23 . A vacuum relief assembly as claimed in  claim 16  wherein said at least one fastener member is secured by a cable seal assembly. 
     
     
         24 . A vacuum relief assembly as claimed in  claim 17  wherein said at least one fastener member is secured by a cable seal assembly. 
     
     
         25 . A vacuum relief assembly as claimed in  claim 18  wherein said at least one fastener member is secured by a cable seal assembly.
