比例溢流閥工作原理是：比例溢流閥通過(guò)彈簧力的大小改變溢流壓力大大小變化，比例電磁鐵作用在彈簧上的力可以按比例調(diào)整，所以就輸入信號(hào)變化比例溢流閥的壓力也會(huì)變化。


定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí)，會(huì)使流量需求減小。此時(shí)溢流閥開(kāi)啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動(dòng)開(kāi)啟）。

穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓，運(yùn)動(dòng)部件平穩(wěn)性增加。

系統(tǒng)卸荷作用：在溢流閥的遙控口串接溢小流量的電磁閥，當(dāng)電磁鐵通電時(shí)，溢流閥的遙控口通油箱，此時(shí)液壓泵卸荷。溢流閥此時(shí)作為卸荷閥使用。

安全保護(hù)作用：系統(tǒng)正常工作時(shí)，閥門關(guān)閉。只有負(fù)載過(guò)規(guī)定的極限（系統(tǒng)壓力過(guò)調(diào)定壓力）時(shí)開(kāi)啟溢流，進(jìn)行過(guò)載保護(hù)，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)*工作壓力高10%～20%）。

實(shí)際應(yīng)用中一般有：作卸荷閥用，作遠(yuǎn)程調(diào)壓閥，作高低壓多級(jí)控制閥，作順序閥，用于產(chǎn)生背壓
