FLOW CHANNEL OPENING/CLOSING APPARATUS
PROBLEM TO BE SOLVED: To provide a flow channel opening/closing apparatus that can keep the instantaneous flow rate of supply water constant, quickly open and close a main valve for starting and stopping water supply, and be downsized.SOLUTION: A flush valve CV as the flow channel opening/closing apparatus incorporates constant flow rate means that operates to keep constant the main flow rate of a flow from a primary-side internal flow channel 20 to a secondary-side internal flow channel 30. The constant flow rate means has a constant flow rate valve body 44 having an inclined surface 441 and a constant flow rate valve seat, operates to adjust the distance between the constant flow rate valve body 44 and the constant flow rate valve seat with the inclined surface 441, and is formed as a valve member 40 including a main valve body 42 and the constant flow rate valve body 44 which are integrated.SELECTED DRAWING: Figure 2
【課題】給水の瞬間流量を一定にしつつ、給水を開始及び停止するための主バルブの開閉を機敏に行うことができ、小型化も図ることができる流路開閉装置を提供すること。【解決手段】この流路開閉装置としてのフラッシュバルブＣＶは、一次側内部流路２０から二次側内部流路３０へ流れる主流量を一定に保つように作動する定流量手段が組み込まれており、定流量手段は、傾斜面４４１を有する定流量弁体４４及び定流量弁座を有し、傾斜面４４１により定流量弁体４４と定流量弁座との距離を調整するように作動するものであり、主弁体４２と定流量弁体４４とが一体化された弁部材４０として形成されている。【選択図】図２
