溢流阀的主要作用是对液压系统定压或进行安全保护口几乎在所有的液压系统中都需要用到它、其性能好坏对整个液压系统的正常工作有很大影响。
在液压系统中维持定压作用是溢流阀的主要用途。它常用于节流调速系统中，和流量控制阀配合使用，调节进人系统的流量，并保持系统的压力基本恒定。如图5-14(a)所示,溢流阀2并联于系统中，进人液压缸4的流量由节流阀3调节。由于定量泵1的流量大于液压缸4所需的流量，油压升高，将溢流阀2打开，多余的油液经溢流阀2流回油箱。因此，泵在这里溢流阀的功用就是在不断的溢流过程中保持系统压力基本不变。
溢流阀用于过载保护的溢流阀一般称为安全阀。如图5-14(b)山所示的变量泵调速系统。在正常工作时.安全阀2关闭,不溢流。只有在系统发生故障，压力升至安全阀的凋整值时,阀口才打开，使变童泵排出的油液经溢流阀2流回油箱，以保证液压系统的安全。
溢流阀还可以做背压阀和卸荷阀(先导式溢流阀)。当溢流阀安装在系统的回油路上，保持系统的回油路有一定的压力，使系统工作较为稳定，此时为背压阀。当先导式溢流阀的控制油口通油箱时。主阀打开，使液压泵泄油，即液压泵卸荷，此时为卸荷压阀。
液压系统对溢流阀的性能要求如下。
(1)定压精度高。当流过溢流阀的流量发生变化时.系统中的压力变化要小，即静态压力超调要小。
(2)灵敏度要高。如图5-14(a)所示。当液压缸4突然停止运动时.溢流阀2要迅速开大，否则。定量泵1输出的油液将囚不能及时排出而使系统压力突然升高，并超过溢流阀的调定压力。称动态压力超调，使系统中各元件及管路压力增加，影响其寿命。溢流阀的灵敏度越高.则动态压力超调越小。
(3)工作要平稳，且无振动和噪声。
(4)当阀关闭时，密封要好，泄漏要小。
对于经常开启的溢流阀，主要要求前三项性能;而对于安全阀。则主要要求第二和第四两项性能。其实，溢流阀和安全阀都是同一结构的阀，只不过是在不同要求时有不同的作用而已。
