PROBLEM TO BE SOLVED: To provide an emergency shut-off valve that allows reliable water cut-off and easy recovery work.SOLUTION: A primary water supply pipe 4 which is connected to a main pipe; a secondary water supply pipe 8 which is connected to an outlet side end for tap water of a water meter M connected to an outlet side end for tap water of the primary water supply pipe 4; a water supply pipe shut-off valve 7 which is disposed between the primary water supply pipe 4 and the water meter M or between the water meter M and the secondary water supply pipe 8 and operated by vibration of a predetermined magnitude generated by an earthquake to shut off the flow of the tap water; and a box 5 which can accommodate the water supply pipe shut-off valve 7 and the water meter M are provided.
【課題】止水を確実に行うことができるとともに、復旧作業を容易に行える緊急遮断弁を提供する。【解決手段】本管に接続される一次側給水管４と、一次側給水管４の水道水の流出側端部に接続される水道用メータＭの水道水の流出側端部に接続される二次側給水管８と、一次側給水管４と水道用メータＭとの間又は水道用メータＭと二次側給水管８との間に配置され、地震により発生する所定の大きさの振動により作動して水道水の流れを遮断する給水管用遮断弁７と、給水管用遮断弁７及び水道用メータＭを収容可能なボックス５とを設けた。【選択図】図３
