COMPRESSED GAS TANK WITH ADAPTER FOR JOINING IT WITH CONNECTING APPARATUS, CONNECTED TO USER, DISTRIBUTOR OR FILLING STATION, PARTICULARLY FOR RESPIRATORY APPARATUS WITH COMPRESSED GAS Russian patent published in 2009 - IPC F16K1/30 F17C13/04 F16L37/34 

FIELD: machine building.

SUBSTANCE: present invention pertains to reinforcement and is meant for joining a tank under high pressure to connecting apparatus, connected to a user. In compressed gas tank (2) there is valve (1) with standard connecting pipe (3) and separate connecting piece (12) threaded into connecting pipe (3) of tank (2). The latter can be joined to reducer (6), distributor or filling station through detachable connecting apparatus (17, 18, 8) made on connecting piece (12) and in connecting apparatus (7). In these apparatus for the position detached from connecting piece (12) there are spring-loaded blocking apparatus for preventing gas leakage and protection from contamination. In connecting apparatus (7) there are spring-loaded blocking elements (10). Detachable connecting apparatus (17, 18; 8) on connecting piece (12) have closing umbrella-shaped blind (17) in locking ring (18) with annular clearance. In the annular clearance there is a locking ring. This ring in the detached state is held between closing umbrella-shaped blind (17) and locking ring (18) such that, when tank (2) is opened, a limited volume of gas can flow out.

EFFECT: increased reliability of connecting the tank to the user, as well as safety of using the tank in detached state.
