德國Rexroth力士樂比例溢流閥主要作用；
德國Rexroth力士樂比例溢流閥工作原理是：比例溢流閥通過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
德國Rexroth力士樂定壓溢流作用：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)開啟）。
德國Rexroth力士樂比例溢流閥穩(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。
德國Rexroth力士樂系統(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。

溢流閥是安全閥，裝在油泵出油處。當(dāng)液壓系統(tǒng)正常工作時(shí)，溢流閥“不動(dòng)作”；當(dāng)液壓系統(tǒng)液壓過載時(shí)，溢流閥“動(dòng)作”，直接將液壓油返回油箱，避免液壓執(zhí)行機(jī)構(gòu)（如，油缸）因機(jī)械過載受損。溢流閥的工作壓力是預(yù)先調(diào)好的，略高于正常工作壓力。
