溢流閥是一種液壓壓力控制閥,。在液壓設(shè)備中主要起定壓溢流作用，穩(wěn)壓,，系統(tǒng)卸荷和安全保護(hù)作用,。 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,，**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）,。
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)載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時(shí)開啟溢流,，進(jìn)行過載保護(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（串在回油路上）。
溢流閥一般有兩種結(jié)構(gòu)：1,、直動(dòng)型溢流閥 ,。2、先導(dǎo)型溢流閥,。
對(duì)溢流閥的主要要求：調(diào)壓范圍大,，調(diào)壓偏差小，壓力振擺小,，動(dòng)作靈敏,，過載能力大，噪聲小,。
