ROBINET POUR BOUTEILLES DE GAZ COMPRIMES OU LIQUEFIES.

摘要

The valve comprises a shutting device (64) between an outlet passage (60) for the gases and an inlet passage (62), an external switching means connected to the said shutting device (64) in order to move the latter between an open position and a shut position and a pressure reducing valve (66) for controlling the gas flow pressure when the shutting device (64) is in the open position.
In order to allow the filling of the bottle and the off-take of the gas through the same opening, a pipe (76) is provided in parallel between the inlet passage (62) and the outlet passage (60) bypassing the pressure reducing valve (64) and is equipped with means allowing the flow of filling gas from the outlet passage (60) towards the inlet passage (62) and preventing the flow of the gases in the opposite direction.
