FLOW PATH OPENING/CLOSING DEVICE
To provide a flow path opening/closing device having a well-maintainable filter part for suppressing the passage of the foreign matters without impairing flow rate performance while preventing foreign matters in service water from being bitten into a main valve element.SOLUTION: A flow path opening/closing device for autonomously stoping the supply of water includes a body part formed with an inflow port for receiving water from a primary side flow path as a water supply source and then delivering it and an outflow port for delivering the water from a secondary side flow path, a valve part having a main valve element and a main valve seat for performing flow path opening/closing between the primary side flow path and the secondary side flow path, and a water stopper 900 provided on the upstream side of the valve part, the water stopper having a stop stopper valve element 910 and a water stopper valve seat 903 for opening/closing an internal flow path 902 of the water stopper, a shaft part 911 for moving the water stopper valve element, a bearing member 920 for bearing the shaft part, and a filter part 930 for suppressing the passage of foreign matters, the filter part being located on the downstream side of the water stopper valve element in the state that the internal flow path is closed by the water stopper valve element and the water stopper valve seat.SELECTED DRAWING: Figure 7
【課題】主弁体に水道水中の異物が噛み込むことを防止するとともに、異物の通過を抑制するフィルタ部のメンテナンス性が良く、且つ流量性能も損なわない流路開閉装置を提供する。【解決手段】自律的に給水を停止する流路開閉装置であって、給水元である一次側流路から水を受け入れて送り出す流入口と、二次側流路から水を送り出す流出口とが形成された本体部と、一次側流路と二次側流路との間の流路開閉を行う主弁体および主弁座と、を有するバルブ部と、バルブ部の上流側に設けられる止水栓９００と、を備え、止水栓は、止水栓の内部流路９０２を開閉するための止水栓弁体９１０と止水栓弁座９０３と、止水栓弁体を移動させる軸部９１１と、軸部を受ける軸受部材９２０と、異物の通過を抑制するフィルタ部９３０と、を有し、フィルタ部は、内部流路を止水栓弁体と止水栓弁座によって閉弁されている状態において、止水栓弁体の下流側に位置している。【選択図】図７
