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。當系統(tǒng)壓力加大時，會使流量需求減小。此時溢流閥開啟，使多余流量溢回油箱，保證溢流閥進口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。
穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓運動部件平穩(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，當電磁鐵通電時，溢流閥的遙控口通油箱，此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。
安全保護作用：系統(tǒng)正常工作時，閥門關(guān)閉。只有負載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啟溢流，進行過載保護，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)較高工作壓力高10%～20%）。
實際應(yīng)用中一般有：作卸荷閥用，作遠程調(diào)壓閥，作高低壓多級控制閥，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、直動型溢流閥 。2、先導型溢流閥。
對溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。
