Valve assembly with check valve for gas container.

摘要

A valve assembly with a check valve for a gas container has a check valve chamber (41) formed in such a portion of a circumferential wall of a stop valve chamber (9) within a valve box (4) as being besides the portion on the side of a stop valve opening and closing manipulation means (17) and the portion on the side of a gas outlet port (11). Within the check valve chamber (41) a check valve body (42) is resiliently urged to a check valve seat (44) for valve closing by means of a checking spring (43). A check valve body opening member (51) for opening the check valve body (42) is arranged so as to face the check valve body (42) from the side of the check valve seat (44) and is adapted to be advanced toward the check valve chamber (41) so as to be changed over to the valve open position (Y) for opening the check valve body (42) and to be retreated from the check valve chamber (41) so as to be changed over to the valve opening cancellation position (X).
