淺談液壓系統(tǒng)溢流閥工作原理

液壓系統(tǒng)中溢流閥的工作原理。
溢流閥是維持閥進(jìn)口壓力近于恒定，系統(tǒng)中多馀的流體通過該閥回流的壓力控制閥。
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。
液壓站廠家定壓溢流作用：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，會使流量需求減小。此時溢流閥開啓，使多馀流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啓）。
穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥産生背壓運(yùn)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(dāng)電磁鐵通電時，溢流閥的遙控口通油箱，此時液壓泵卸荷。溢流閥此時作爲(wèi)卸荷閥使用。
安全保護(hù)作用：液壓系統(tǒng)正常工作時，閥門關(guān)閉。隻有負(fù)載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啓溢流，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)最高工作壓力高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，作高低壓多級控制閥，作順序閥，用于産生背壓（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(dǎo)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。
