Abstract

PURPOSE: To shut off the fluid passage in case of the earthquake, etc. by clamping the valve closing member, which is removably supported by the spring, on the valve seat.
CONSTITUTION: The fluid normally flows through the fluid inlet port 3 into the casing 2 and passes through the play clearance 28 between the casing 2 and the resistance 27 and the port 29 formed in the resistance plate, and further flows through the gap of the leaf spring member 12 of the spring supported member 11 and flows out through the liquid outlet port 4. In case of the earthquake, the valve closing member 8 is vibrated to bend the leaf spring member 12 of the spring supported member 11, and the valve closing member 8 comes off the spring supported member 11 and falls to be clamped with the valve seat 6 being guided by the guide 7 to automatically shut off the flow passage. When a great amount of fluid over the prescribed flow rate flows out, the resistance plate 27 is pushed down by the pressure difference and shut off the passage in the same way.
