Abstract

PURPOSE: To assure positive functioning of the emergency valve to shut off gas supply in response to a seismic vibration, by pulling in a pin, which prevents the valve body from sliding, by means of the shaking of a weight.
CONSTITUTION: When an earthquake occurs, a weight 15 is shaked and the end 14' of a pin 14 is prized upward by means of a lever action of the circular edge provided at the bottom of the weight 15. Accordingly, the pin 14 is pulled up from the sliding path 12 permitting a valve body 11 slide along the path 12 by means of gas pressure to dislocate a penetration hole 16 off the alignment with the main gas passage 3, and thus shutting the gas supply. Resetting of the emergency valve is accomplished by screwing a return screw 17 into the sliding path 12 and moving the valve body 11 to the left. When the pin 14 is thrusted into the sliding path 12, the return screw 17 is screwed back to the original position.
