150LB/PN16/10K Japanese standard check valve立式止回阀，垂直安装逆止阀阀瓣在流体压力作用下开启，流体从进口侧流向出口侧。当进口侧压力低于出口侧时，阀瓣在流体压差、本身重力等因素作用下自动关闭以防止流体倒流 Vertical check valve, vertically installed check valve disc opens under fluid pressure, and fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve disc automatically closes under factors such as fluid pressure difference and its own gravity to prevent fluid backflow
进口立式止回阀 垂直安装逆止阀性能说明 Function description
立式止回阀（垂直安装逆止阀）由于采用弹簧支撑阀芯，故采用立式安装。正常处于关闭状态，由于管线中进口端介质的压力作用，而克服弹簧阻力使阀门开启。当进口端介质压力低于出口端时，弹簧将阀芯推向阀座而使阀门关闭，阻止介质逆流 RETZ The vertical installation of check valve (vertical check valve) is adopted because the valve core is supported by spring. The valve is normally closed, and the valve is opened by overcoming the spring resistance due to the pressure of the medium at the inlet end of the pipeline. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core to the valve seat to close the valve and prevent the medium from flowing back
