PRESSURE DETECTION TYPE CHECK VALVE
To provide a highly functional valve which includes a pressure detection function, cutting-off/opening function of a flow passage, a function of a check valve and the like.SOLUTION: A pressure detection type check valve includes: an inlet 3; an outlet 4; an inlet side flow passage 5; a flow passage space chamber 6 communicating with the inlet side flow passage 5 and connected to the outlet 4; a deformable member (umbrella part 11, beak part 102) having elasticity, and provided so as to deform by receiving an external force; and a diaphragm 16 energized by a spring 17 and displaced by receiving an external force. The deformable member is deformable between the shape for opening the flow passage and the shape for cutting it off, on the basis of a force by elasticity and a force by a pressure in the flow passage space chamber 6 resisting the force. The diaphragm 16 is a wall member of the flow passage space chamber 6 and it is constituted to be displaceable between the position for operating a pump 40 and the position for stopping the operation of the pump 40, on the basis of the energization force of the spring 17 and a force by the pressure in the flow passage space chamber 6 resisting the energization force.SELECTED DRAWING: Figure 2
【課題】圧力検知機能、流路の遮断／開放機能、逆止弁の機能等を備えた高機能の弁を提供する。【解決手段】入口３と、出口４と、入口側流路５と、入口側流路５と連通するとともに出口４につながる流路空間室６と、弾性を有し、外力を受けて変形可能に設けられた変形部材（傘部１１，くちばし部１０２）と、バネ１７により付勢され外力を受けて変位するダイヤフラム１６と、を備え、変形部材は、前記弾性による力と当該力に対抗する流路空間室６における圧力による力とに基づいて、流路を開放する形と遮断する形とに変形可能であり、ダイヤフラム１６は、流路空間室６の壁部材であり、バネ１７の付勢力と当該付勢力に対抗する流路空間室６における圧力による力とに基づいて、ポンプ４０を作動させる位置とポンプ４０の動作を停止させる位置とに変位可能な構成としてある。【選択図】図２
