Abstract: An LP gas container valve to be mounted on a propane gas container is provided for preventing a fire, explosion or other accident at the time of a disaster. The LP gas container valve comprises a valve body having a valve outlet and a gas passage leading from an inlet connection to a propane gas container to the valve outlet, a closing valve (attached to the valve body) for opening and closing the gas passage, a safety valve (attached to the valve body) actuated in response to an excessive elevation in gas pressure, a branching point in the gas passage leading to the safety valve, and a ball located in the gas passage between the branching point and the closing valve. The ball is movable between its stationary position in normal operation and its gas cutting off position in response to an excessive elevation in gas pressure, both of which are located between the closing valve and the branching point in the gas passage.
