减压阀的分类

减压阀可分为波纹管式（直接作用式）减压阀、活塞式减压阀、薄膜式减压阀。

① 波纹管式（直接作用式）减压阀。***简单的减压阀，直接作用式减压阀，带有平膜片或波纹管。独立结构，*在下游安装外部传感线。是三种减压阀中体积***小、使用***经济的一种，专为中低流量设计。直接作用式减压阀的精确度通常为下游设**的（+10%~-10%)；

② 活塞式减压阀。该类型的减压阀集两种阀——导阀和主阀于一体。导阀的设计与直接作用式减压阀类似。来自导阀的排气压力作用在活塞上，使活塞打开主阀。如果主阀较大，无法直接打开时，这种设计就会利用人口压力打开主阀。因此，这种类型的减压阀，与直接作用式减压阀相比，在相同的管道尺寸下，容量和精确度（+5%~-5%）高。与直接作用式减压阀相同的是，减压阀内部感知压力，无须外部安装传感线；

③ 薄膜式减压阀。这种类型的减压阀中，双膜片代替了内导式减压阀中的活塞。这个增大的膜片面积能够打开大的主阀，并且在相同的管道尺寸下，其容量比内导式活塞减压阀大。另外，膜片对压力变化为敏感，精确度可达（+1%~-1%）。精确性高是由于下游传感线的定位（阀的外部），其所在位置气体或液体动荡少。该减压阀非常灵活，可以采用不同类型的导阀，如压力阀、温度阀与空气装载阀。
