Abstract

PURPOSE:To prevent a device from erroneously cutting off gas by detecting the gas except its leakage by forming the device so as to break a flow of gas through both the detection of gas and the detection of its flow amount. CONSTITUTION:A gas leakage shutoff device provides a gas detecting means A detecting gas of predetermined concentration or more to generate a detection signal, means C detecting a predetermined flow amount of gas in a gas flow path B generating a gas flow amount signal in accordance with detecting this predetermined flow amount of gas, gas flow shutoff means E provided in the gas flow path B and a gas flow shutoff control means D supplying a gas shutoff signal to the gas flow shutoff means E blocking the gas flow path B being based on the detection signal from the gas detecting means A and the gas flow amount signal from the gas flow amount signal generating means C.
