Abstract
PURPOSE: To automaticallty stop excessive effluence of gas and permit simple restoration to the state of reuse by installing a spherical valve which can close a valve seat on the gas inflow side and installing a porjection body for reducing the gas volume of the gas flow passage between a closing body and a spherical valve.
CONSTITUTION: When gas G flows out excessively due to slipping-off of a rubber hose H, a spherical valve 13 floats-up due to the abnormal fluid pressure of the gas G, and the valve hole 9 of a vlave seat 8 is closed. In return to the state of resuse from the state described above, if a closing knob 7 is turned in the direction of closure, a gas flow passage 2 is shut off by a closing element 5, and a projection body 19 is pushed-out rightward by the engaging projection piece 18 of the closing element 5, and projects to the flow passage 2. Then, the volume of the flow passage 2 between the closing element 5 and the spherical valve 13 is reduced by the same volume to the projection prortion of the projection body 19, and the pressure in the flow passage 2 increases, and the spherical valve 13 falls from the valve seat 8.
