記第１請求項記載の過流出防止弁。[Claims for Utility Model Registration] (1) Consists of a casing having a gas passage inside and a safety valve movably housed within the gas passage of this casing, and usually the safety valve is provided in the gas passage. In the overflow prevention valve, which separates from the valve seat to allow gas flow, and when gas flows in an overflow state, the safety valve seats on the valve seat and blocks the gas flow, the safety valve moves closer to the valve seat. An overflow prevention valve characterized in that it is equipped with a braking mechanism that applies sliding friction resistance between a casing and a safety valve when the safety valve is overflowed. (2) The above-mentioned safety valve is composed of a shaft portion whose axis extends in the direction of movement thereof, and a seal portion that seats on the valve seat of the casing, and the safety valve is supported by inserting the shaft portion so as to be movable in the axial direction. The braking mechanism is attached to the casing via a support ring, and the braking mechanism has a spiral structure that is provided on the outer peripheral surface of the shaft portion of the safety valve and the inner peripheral surface of the support ring of the casing, and that mesh with each other and slide. The overflow prevention valve according to claim 1, characterized in that it is composed of a protrusion and a guide groove.
