  减压阀的是靠阀内流道对水流的局部阻力降低水压,水压降的范围由连接阀瓣的薄膜或活塞两侧的进出口水压差自动调节。减压阀是采用控制阀体内的启闭件的开度来调节介质的流量,将介质的压力降低,同时借助阀后压力的作用调节启闭件的开度,使阀后压力保持在一定范围内,并在阀体内或阀后喷入冷却水,将介质的温度降低称为减压减温阀,特点是在进口压力不断变化的情况下,保持出口压力和温度值在一定的范围内。

  The Pressure Reducing Valve Reduces The Water Pressure By The Local Resistance Of The Flow Passage In The Valve. The Range Of The Water Pressure Drop Is Automatically Adjusted By The Film Connecting The Valve Disc Or The Inlet And Outlet Water Pressure Difference On Both Sides Of The Piston. The Pressure Reducing Valve Is To Control The Opening Of The Opening And Closing Parts In The Valve Body To Adjust The Flow Of The Medium And Reduce The Pressure Of The Medium. At The Same Time, With The Help Of The Pressure Behind The Valve, The Opening Of The Opening And Closing Parts Is Adjusted To Keep The Pressure Behind The Valve In A Certain Range, And The Cooling Water Is Injected Into The Valve Body Or Behind The Valve To Reduce The Temperature Of The Medium, Which Is Called The Pressure Reducing And Desuperheating Valve Keep The Outlet Pressure And Temperature In A Certain Range.
