Abstract
PURPOSE: To make it possible to shut off flow passage of gas, etc. positively in response to vibration with a simple structure in such a way that a supporting rod of a weight to rock by vibration is interlocked with a boss of a valve rod centrically fitted in free command of rocking, a coil spring and the valve part are installed at both ends of the valve rod.
CONSTITUTION: When a settled vibration is acted by earthquake, etc., a weight 3 is swiveled against tractional force of a coil spring 9 binding a supporting rod 6 with a boss 34 under a valve rod 8, a rod part 33 of the valve rod 8 is pulled down to the coil spring 9 by releasing engaged condition of the boss 34 with the supporting rod 6. In the meantime, a packing 11 of the valve part 32 having an axle rod 10 lifted up as its fulcrum oppositely tightly closes a downward cylindrical valve seat 12 in possession of a passage bore 31 to conduct to an effluent passage 22. After automatically closing the plug, for the sake of operating the device again, it is enough to lift up the rod part 33 through the axle rod 10 with use of a handle 14 at the external part of the valve casing 1, the weight 3 returns to the perpendicular direction, the supporting rod 6 comes to be engaged with the boss 34, the valve part 32 releases the valve seat 12.
