置。[Claims for Utility Model Registration] In the upstream part of the gas supply path 1, one end is a gas inlet 11 and the other end is a gas outlet 12, and a valve seat part 13 is provided between the inlet 11 and the outlet 12. A valve body 14 is housed in a valve housing chamber R1 provided upstream of the valve seat portion 13 of the valve body 10, and a valve rod 15 of the valve body 14 has a valve body 14 interposed therebetween. Downstream chamber R2
The valve rod 15 is connected to a moving part 16 that moves based on the internal pressure difference between the valve housing chamber R1, the valve downstream chamber R2, and the compartment R3, and a moving part 16 that moves according to the internal pressure difference between the valve housing chamber R1, the valve downstream chamber R2, and the compartment R3 is connected to A spring 17 is arranged to open the valve body 14, and the other end of the sub-pipe line 2, one end of which extends near the downstream end of the gas supply line 1, is provided at the mouth 18 of the compartment R3. On the downstream side of the gas supply line 1 and the sub-pipe line 2,
Normally, the other end of the sub-pipe line 2 is opened to the atmosphere, and when opening the appliance plug 3 of the gas appliance F connected to the downstream end of the gas supply line 1, first, the other end of the sub-pipe line 2 is opened to the atmosphere. A gas supply safety device comprising a valve 20 that closes the gas supply line 1 and then communicates the gas supply line 1 and the auxiliary line 2 for only a certain period of time.
