升降式止回阀是指依靠介质本身流动而自动开、闭阀瓣,用来防止介质倒流的阀门,又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门,其主要作用是防止介质倒流、防止泵及驱动电动机反转,以及容器介质的泄放。止回阀还可用于给其中的压力可能升至超过系统压的辅助系统提供补给的管路上。止回阀主要可分为旋启式止回阀(依重心旋转)与升降式止回阀(沿轴线移动)。

纵贯式蝶式止回阀介质进出口通道偏向与阀座通道偏向垂直;立式升降式止回阀(Aetv Lift Check Valve),其介质进出口通道偏向与阀座通道偏向类似,其运动阻力较纵贯式小。

升降式止回阀使用一个可承受弹簧载荷的轻量阀瓣,阀瓣的升程不高。
Lift check valve with a spring load can withstand light valve flap, flap valve lift is not high.
其中止回阀就属于这种类型的阀门,它包括旋启式止回阀和升降式止回阀。

由于这种止回阀能够在重力和介质倒流撞击启闭件之前关闭阀门,因此这种直通弹簧驱动升降式止回阀也称为“静音”止回阀。
The in-line spring-actuated lift check also is referred to as the "silent check" because the spring closes the valve before gravity and fluid reversal can slam the valve closed.
