Abstract

PURPOSE:To provide a positive prevention of various accidents of gas leakages by a method wherein a gas flow is generated after opening an equipment plug, a valve is opened by detecting a flow of gas with a gas flow sensor and in turn if a flame is gone out, this diminished state is detect by a flame sensor and then the valve is closed. CONSTITUTION:When an equipment plug 2 is opened to start using of gas, a gas flow is generated. This state is detected by a main body 10 of a gas flow sensor, a signal of 'opened valve' is transmitted from a transmitter 13 to a receiver 16 with gas within a pipe 15 being applied as medium, a solenoid valve 17 is opened and then an ignition is carried out. Simultaneously, a flame sensor 12 also starts its operation and starts to monitor a flame. If failure ignition is generated, the flame sensor 12 detects that the flame is not generated, a signal of 'closed valve' is generated from the transmitter 13 and then the solenoid valve 17 is closed. If a piping 15 is broken and a flow of gas is terminated, the signal of 'opened valve' sent from the transmitter 13 does not reach the receiver 16, resulting in that the solenoid valve 17 is closed.
