Valve for a non-refillable pressure vessel and a pressure vessel with such a valve device

摘要

Valve device (12, 52) to prevent refilling of a pressure container (10), which valve device (12, 52) comprises a valve housing (40) having a valve chamber (43) provided with two ports (41, 42), a valve body (44) placed in the valve chamber (43) and provided with an axially movable and spring-loaded valve cone (45) having a valve seat (46), which seals against the valve body (44) when the valve cone (45) is unloaded, the valve body (44) limiting the valve chamber (43) at one port (41 ) thereof and the valve chamber (43) being provided with a non-return valve (47) at the other port (42) thereof, which non-return valve (47) is arranged to sealingly abut against the valve housing (40) at a positive pressure in the valve chamber (43). The valve housing (40) is provided with a filling channel (480, 880), which extends from a position between the two ports (41, 42) of the valve chamber (43) through the valve housing (40) and out through the outer surface (481, 881) thereof and that an, at least initially, movable interrupt member (482, 882) is connected to the filling channel (480, 880) to close the filling channel (480, 880) after the pressure container (10) has been filled with pressure fluid. The invention also concerns a pressure container provided with such a valve device.
