特徴がある。The present invention has improved the above-mentioned drawbacks, and its main structure is to construct an inverted-shaped gas passage inside so that gas flows in from below and flows out horizontally, and a fuse ball is placed inside the closure. In a gas cock with an overflow prevention mechanism that incorporates a gas cock, a through hole is provided on the opposite side of the horizontal gas outlet formed in the closure, and the outer surface is the same as the tapered surface of the closure. A holding part having a tapered surface is fitted, a bottomed groove is formed in the vertical direction on the holding part, and an inverted-shaped reset member consisting of a horizontal part and a vertical part is inserted into the groove. The reset member is rotatably engaged by a shaft pin, and the tip of the horizontal part of the reset member can kick the fuse ball downward from above when it comes into close contact with the valve seat provided in the closure. At the same time, a spring is attached above the horizontal part of the reset member to rotate the horizontal part downward, and a spring is installed at the lower end of the vertical part of the reset member to protrude toward the tapered surface side of the cock body. At the same time, a concave groove is formed on the tapered surface of the cock body at a position where the retaining part of the reset member faces when the closing member is fully opened, so that the retaining part of the reset member and the concave groove are formed. This is a gas cock with an overflow prevention mechanism configured such that the reset member is rotated clockwise around the shaft pin by the spring when the gas cock faces, and is convenient for downsizing the gas cock and for assembly, disassembly, and repair. The unique feature is that the reset mechanism is unitized.

The reset mechanism can be built into 7, and when repairing parts, the reset mechanism can be easily taken out and repaired by taking out the closure 7.
Reincorporation is possible.
ハ リセット部材１９は軸ピン２２を中心とした回転運
動によりヒユーズボール１２を蹴り落とすものであるか
ら、従来のように摩耗が無いと共に組み立てに際して蹴
り落としのタイミング調整を行う必要がない。Since the reset member 19 kicks down the fuse ball 12 by rotating around the shaft pin 22, there is no wear unlike in the conventional case, and there is no need to adjust the kick-off timing during assembly.
ニ リセット部材１９（リセット機構）は閉子７内にす
べて組み込まれているので、この点がらもガスコック本
体１の小型化が可能である。(d) Since the reset member 19 (reset mechanism) is entirely incorporated into the closure 7, the gas cock main body 1 can be downsized in this respect as well.
