動子に突設して成る安全装置付ガスコック。In gas cocks that open and close gas flow by rotating the operating knob, the gas flow path is equipped with a safety shutoff valve that closes the gas flow at appropriate gas pressure. A closure is arranged so that the flow direction and the axial direction of the closure are parallel, a valve seat is formed in the gas flow passage so as to face the end face of the closure, and a valve body that can open and close the valve seat is attached to the valve. It is placed on the closing side of the seat, one end of the abbreviated operating rod is pivotally connected to the valve body, and the approximate center of the operating rod is pivotally connected to the mounting base on the side of the valve body, and the end face of the closing body is An interlocking element that can rotate together with the closing element is arranged at the holder, and a closing spring that presses the valve element against the valve seat is interposed between the interlocking element and the valve element, and the operating rod is activated only when the closing element is fully opened. A gas cock with a safety device comprising a driving part protruding from an interlocking element that can move the other end to the outer periphery and separate the valve body.
