FIELD: machine building.
SUBSTANCE: gas connecting valve permits connection or disconnection of gas connecting plug only in case when an additional stop valve is closed manually. Body of gas connecting valve has a support platform for a switch, which is equipped on one side with a switching profile, against which a pusher installed in the main body leans with its one end. The other end of pusher is connected to plate of stop valve installed in gas cavity of the main body. On the other side the switch is connected to stop device, which is used to prevent displacement of gas connecting plug insertion/withdrawal depending on the switch position.
EFFECT: invention improves reliability of connection.
