单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。

单向阀又称止回阀或逆止阀。用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。
单向阀有直通式和直角式两种。直通式单向阀用螺纹连接安装在管路上。直角式单向阀有螺纹连接、板式连接和法兰连接三种形式。液控单向阀也称闭锁阀或保压阀，它与单向阀相同，用以防止油液反向流动。但在液压回路中需要油流反向流动时又可利用控制油压，打开单向阀，使油流在两个方向都可流动。液控单向阀采用锥形阀芯，因此密封性能好。在要求封闭油路时，可用此阀作为油路的单向锁紧而起保压作用。液控单向阀控制油的泄漏方式有内泄式和外泄式二种。在油流反向出口无背压的油路中可用内泄式；否则需用外泄式，以降低控制油压力。

3）先导溢流阀的主阀上腔压力，是由先导阀加于控制的。如果先导阀正常工作，即主阀上腔有先导阀规定的压力，则整个溢流阀就会在系统压力到达调定压力时其主阀口打开一定的开度，一方面能将系统多余流量流回油箱，另一方面又能维持系统的压力为先导阀的调定值。可见，先导阀主要管压力，主阀服从先导阀的领导，在先导阀动作时将主阀口开到合适大小，正好将多余流量流出去，又不影响系统压力。

先导式减压阀
内部先导式减压阀当减压阀的输出压力较高或通径较大时，用调压弹簧直接调压，则弹簧刚度必然过大，流量变化时，输出压力波动较大，阀的结构尺寸也将增大。为了克服这些缺点，可采用先导式减压阀。先导式减压阀的工作原理与直动式的基本相同。先导式减压阀所用的调压气体，是由小型的直动式减压阀供给的。若把小型直动式减压阀装在阀体内部，则称为内部先导式减压阀；若将小型直动式减压阀装在主阀体外部，则称为外部先导式减压阀。与直动式减压阀相比，增加了由喷嘴4、挡板3、固定节流孔9及气室B所组成的喷嘴挡板放大环节。当喷嘴与挡板之间的距离发生微小变化时，就会使B室中的压力发生根明显的变化，从而引起膜片10有较大的位移，去控制阀芯6的上下移动，使进气阀口8开大或关小、提高了对阀芯控制的灵敏度，即提高了稳压精度。
在主阀体外部还有一个小型直动式减压阀由它来控制主阀。此类阀适于通径在20mm以上，远距离(30m以内)、高处、危险处、调压困难的场合。
