Abstract

PURPOSE: To stop the pathway of gas inside the upstream side coupler immediately when earthquake occurs by providing a stop valve between the upstream side coupler and the downstream side coupler in a pipeline for propane gas bomb, etc., and a gas apparatus.
CONSTITUTION: When a bomb 41 is fallen down, a downstream side coupler 5 can overcome, together with a nut 37, the tension of a fixing ring 11 and is removed from a stop valve 9. The stop valve 9 is moved toward the left side by means of a spring 31, a closing part 15 is closely adhered to a valve seat 13, and the flow of gas is air-tightly interrupted by an O-ring 17. A small hole 33 provided in the stop valve 9 introduces a gas pressure through a through hole 21, whereby pressures on both sides of the O-ring 27 are equalized and the movement of the stop valve 9 is smoothened. The small hole 35 is provided to draw air inclosed by the O-ring 25 when inserting the coupler 5 into the stop valve 9, and its outlet is led to the open air.
