Filling valve for liquefied gas containers

摘要

The filling valve depicted in the drawing for liquefied gas containers, having a pivotable nonreturn valve 20 as a safety closure providing a coarse seal, and having a nonreturn valve cone 6 which provides a soft seal and is intended to provide a gas-tight seal with a screw cap 2 and a sealing cap 1 as an additional safety closure, has a flange 11 with screw holes 12 to connect it immovably and in a manner secure against twisting and the action of fire to the mating flange on the liquefied gas container. The risk of leakage at the previous threaded joint between the filling-valve connnection head 3 and the filling-valve housing 10 is avoided by means of the flanged joint.
