Abstract

PURPOSE:To prevent an overheating of a solenoid and prevent a returning movement of the solenoid during an alarm operation by a method wherein the solenoid may keep a shutting-off of a supplying of gas even if the power feeding thereto is terminated after the solenoid operated in response to the leaked gas alarm is operated at once. CONSTITUTION:When a gas leakage is sensed by a sensor of an alarm device, the alarm buzzer is rung and at the same time the reed switch 15 is energized. At this time, the reed switch 15 is turned on by a magnet 14 of the lever 8 located at a returning position and the solenoid 2 is energized. Then, the connector 19 is pulled down against the spring 20 and the stopper plate 3 is rotated around the pin 4 through the pin 13 against the spring 5. Thus, the pin 12 is released from the engaging hook 3a, the manual lever 7 and the lever 8 are rotated around the axis 17 by a biasing force of the spring 18. Thereby, the pushing plate 16 pushed by the cam 6 is released and the valve not shown operates to close the gas pipe through the pushing plate 16 and an integral rod 10.
