Gas plug for connection between a fixed gaseous fluid supply network and a device supplied by the gaseous fluid

摘要

The plug has a casing (2) for housing a rotative valve with a valve body (6) and a spherical slide gate (7). A locking system prevents rotation of the slide gate by locking the slide gate on the body when the valve is closed and by locking a male type connection end fitting (18) on the body after linking the body on a gaseous fluid outlet connection (17) when the valve is open. A closing unit closes a protection cover (5) of a facade (3) of the casing and permits automatic return of the cover to an initial position in which the cover completely closes an opening (4) in the facade.
