Abstract

PURPOSE: To close the valve for the commercial gas automatically and exactly by mechanically connecting the main or auxiliary valve, which has an elastically closing mechanism, to the earthquake sensor.
CONSTITUTION: The arm 7 is provided to the valve lever 4, which is fixed to the ring valve mechanism 2 and openings 3, 3' for connecting the external hose, and the end of which is fixed to the recovery lever 6, so that the arm is perpendicular to the axial direction of the lever 4, the free end of the arm is connected to the spring 8 the other end of which is fixed to the case 1, the trigger plate 14 is located between the weight seat 11 and the shaking disc 13 of the earthquake sensor, one end 14b of the trigger plate is locked to the curb 6' of the recovery lever. When the building is shaked by the earthquake and the case 1 fixed to the wall is trembled beyond the action of weight 9, the disc 13 is moved, the triggering plate 14 is pushed up, the recovery lever 6 is unlocked, the valve lever 4 is turned by the action of spring 8, and the valve 2' is closed.
