Abstract

PURPOSE: Through DTC element which temperature changes relating with a senser, output of constant voltage power like battery is charged to an electromagnetic valve. By doing so, safety device can perfectly be operated.
CONSTITUTION: The device is equipped with an electromagnetic valve 5, an oxigen density battery 1, PTC element and a constant voltage power 8 and output of the oxigen density battery 1 is input directly to the electromagnetic valve 5. Then, when ambient oxigen density decreases, oxigen inside a combustion flame 1A lacks and reduction flame produces and it develops in such a way that it is in contact with an electrode 31 of other side of a battery 3. Then, output of the oxigen density battery 3 decreases and so the electromagnetic valve 5 operates in such a way that a valve cover 54 closes a vlave opening 55 to stop the supply of gas.
