止回阀  能自动阻止流体回流的阀门,又称单向阀。通常,流体在压力作用下使阀门的阀瓣开启,并从进口侧流向出口侧。当进口侧压力低于出口侧时,阀瓣在流体压力和本身重力的作用下自动地将通道关闭,阻止流体逆流。按阀瓣运动方式不同,止回阀主要分为升降式、旋启式和蝶式3类(见图)。升降式止回阀的阀体多与截止阀阀体相似,它的流体阻力较大。这类止回阀为高压小口径,常采用圆球形阀瓣。旋启式止回阀对流体的阻力较小,一般适用于中小口径、低压大口径管道,常在阀的通道隔板上设置多个阀瓣,成为多瓣式。蝶式止回阀的形状与蝶阀相似。它结构简单,对流体的阻力小。止回阀如关闭过快,可能会在液体管道中引起液击,产生噪声,甚至导致阀门零件的损坏。为避免这种情况,需要时可选用有缓冲功能的止回阀,以延长关闭时间。
