Abstract
PURPOSE: To provide a compact, rapid operated valve with earthquake sensors which is operated correctly only when an earthquake is occurred, by opening a container when a plurality of earthquake sensors are all operated, and rapidly operating the valve by the pressure of high-pressure gas thus produced.
CONSTITUTION: An earthquake sensor consisting of earthquake sensing section 5, actuator 4, valve 3, etc. is fixed vertically on a wall. When the magnitude of earthquake exceeds a predetermined value, earthquake-sensitive balls of two ball dropped type earthquake sensors 15, 16 are both dropped and holding members 17, 18 are turned. Resultantly, needle 13 is moved upward and rod 10 is unclocked since pressure of stopper ball 14 on tapered face 13a is removed. Rod 10 is made to slide downward at a high speed by spring 12 and cover 7a of container 7 is opened by cutter 11. High-pressure gas in container 7 is supplied to actuator 4 via gas supply passage 22 and valve 4 in hydraulic oil supply pipe 2 is opened through operation of piston 24. Thus, it is enable to provide a emergency operating valve with earthquake sensors which can be operated correctly only when an earthquake is occurred.
