Abstract
PURPOSE: To highly reliably prevent gas explosion by a gas safety valve, wherein an ON-OFF valve is directly connected to a gas cylinder, and a pressure-reducing valve connected to the ON-OFF valve in series is housed in a housing common to the ON-OFF valve, adapted to be closed by detection of gas leakage.
CONSTITUTION: When gas is supplied, a solenoid 18 is fed by an electric current to move down a valve body 13 by the magnetic power against a spring 14 to open an opening OR0. Then the gas from a source of gas is introduced from a connecting pipe 1, and after the pressure is regulated by the pressure-reducing valve 12, it is allowed to flow into a connecting pipe 2. In this gas supplying state, when gas leakage from an end gas appliance is detected by a gas leakage detector (not shown), the feeding of the electric current to the solenoid 18 is cut off by a control means so that the valve body 13 is closed by the spring 14. If the solenoid 18 heats, a screw 17 is fused by the heat, a yoke 19 drops with the solenoid 18, and therefore the valve body 13 remains closed irrespective of the feeding of electric current to the solenoid 18.
