常開式充液閥的優(yōu)點(diǎn)在于充液過程中不需要克服彈簧力，從而減少了吸油阻力。但結(jié)構(gòu)較復(fù)雜，制造要求也較高。

常開式充液閥。閥芯在彈簧的作用下停在閥上部，充液閥處于開啟狀態(tài)。當(dāng)轉(zhuǎn)入工作行程時(shí)，先在充液閥的控制口通入壓力油，閥芯下行，充液閥關(guān)閉。由于閥芯上部面積略大于其下部面積，故隨著液壓缸油壓的升高，充液閥越關(guān)越緊。當(dāng)活塞回程時(shí)，液壓缸先行卸壓，且充液閥的控制口與油箱相通，充液閥可自動(dòng)開啟，使液壓缸中的油液大量排回充液油箱。RV3-10-S-0-36/18?

充液閥的充液過程為:當(dāng)蓄能器的壓力低于充液閥設(shè)定的下限壓力時(shí)，作用在上限單向閥閥芯3上的液壓力低于先導(dǎo)閥4左端彈簧8的作用力，使下限單向閥6關(guān)閉，上限單向閥3打開，蓄能器內(nèi)的壓力油經(jīng)先導(dǎo)閥芯4、節(jié)流通道Ⅱ進(jìn)入主閥右腔，推動(dòng)主閥芯9克服左腔壓力向左移動(dòng)，逐漸降低主閥開度，P與O口間的節(jié)流作用造成P口壓力增高。隨后P口與A口間的單向閥打開，經(jīng)節(jié)流口向蓄能器供液。當(dāng)蓄能器壓力達(dá)到上限時(shí)，作用在先導(dǎo)閥右端單向閥閥芯3的液壓力大于左端彈簧壓力，下限單向閥6打開，上限單向閥3關(guān)閉，主閥右腔經(jīng)先導(dǎo)閥于T口相通泄壓，在左端壓力作用下克服右端彈簧壓力右移，P口與A口間的單向閥關(guān)閉，恢復(fù)全流量向下游系統(tǒng)供液，充液過程結(jié)束。DG4V-3-6C-VM-U-H-60?
