PROBLEM TO BE SOLVED: To provide a gate valve for a water cutoff device that fully withstands water pressure even when a bag is inflated inside a water supply pipe.SOLUTION: A plug-like head part 3 is provided to be inserted into/removed from a pierced hole P1 formed on a water supply pipe P. A base part 4 is hung from a lower rear part of the head part 3, the base part having a height slightly shorter than an inner diameter of the water supply pipe P. An inflatable/deflatable bag 8 is provided on a front surface of the base part 4, the inflatable/deflatable bag supplying and draining a fluid through the head part 3 and the base part 4 and being capable of closing inside the water supply pipe P water-tightly when inflated. A curved wing body 6 is hinged on right and left sides of the base part 4, the wing body being swung by remote controlling means 5 between a bent state that is bent toward a front side of the base part 4 and an extended state that extends toward a side of the base part 4. The wing body 6 encloses the bag 8 in a deflated state while in the bent state, and is set to enable accommodation below the head part 3 so that the wing body does not protrude outside of an outer periphery of the head part 3. When in the extended state, the wing body is set to spread in a disc form with a diameter slightly smaller than the inner diameter of the water supply pipe P, along with the base part 4.SELECTED DRAWING: Figure 9
【課題】水道管内でバッグを膨張させてもその水圧に充分抵抗できる様にした止水装置用仕切弁を提供する。【解決手段】水道管Ｐに形成された穿孔P1に挿脱可能な栓状の頭部３を設け、該頭部３の後方下部に水道管Ｐの内径より丈が若干短い基幹部４を垂設し、該基幹部４前面に頭部３と基幹部４を通じて流体が給排され、膨張状態で水道管Ｐ内を水密状に閉塞可能と成した膨縮自在なバッグ８を設けると共に、基幹部４の左右に基幹部４前方への屈曲状態と基幹部４側方への伸展状態に遠隔操作手段５にて揺動可能な弓形の翼体６を蝶着し、該翼体６は前記屈曲状態で収縮状態のバッグ８を抱囲すると共に、頭部３下方に頭部３外周より外方へ食み出ない様に収容可能に設定され、前記伸展状態で基幹部４と共に水道管Ｐの内径より若干小径な円盤状に展開可能に設定する。【選択図】図９
