液壓系統(tǒng)順序閥與溢流閥區(qū)別
液壓系統(tǒng)順序閥和溢流閥的區(qū)別。
液壓系統(tǒng)中順序閥與溢流閥相仿,爲(wèi)使執(zhí)行元件準(zhǔn)確實(shí)現(xiàn)順序動(dòng)作,要求調(diào)壓偏差小。爲(wèi)此,應(yīng)減小調(diào)壓彈簧的剛度。其與溢流閥的區(qū)別在于它通過(guò)閥門的阻力損失接近于零。
(1)內(nèi)控式直動(dòng)順序閥與直動(dòng)式溢流閥的區(qū)別
內(nèi)控式直動(dòng)順序閥的工作原理與直動(dòng)式溢流閥相似,區(qū)別在于:二次油路即出口壓力油不接回油箱,因而洩漏油口必須單獨(dú)接回油箱,爲(wèi)減少調(diào)壓彈簧剛度,設(shè)置了控制柱塞。
內(nèi)控式順序閥在其進(jìn)油路壓力達(dá)到閥的設(shè)定壓力之前,閥口一直都是關(guān)閉的,達(dá)到設(shè)定壓力后,閥口才開啓,使壓力油進(jìn)入二次油路,去驅(qū)動(dòng)另一執(zhí)行元件。
(2)卸荷溢流閥與外控順序閥作卸荷閥的區(qū)別
卸荷溢流閥主要用于液壓系統(tǒng)裝有蓄能器的液壓回路中,當(dāng)蓄能器充液壓力達(dá)到卸荷溢流閥的設(shè)定壓力時(shí),它自動(dòng)使液壓泵卸荷。卸荷溢流閥內(nèi)裝單向閥,用來(lái)防止蓄能器中的壓力油倒流。此時(shí),由蓄能器向系統(tǒng)供油并保持壓力。當(dāng)蓄能器中油液壓力降到卸荷溢流閥的設(shè)定壓力時(shí),卸荷溢流閥關(guān)閉,液壓泵恢複向蓄能器充液。液壓蓄能器增速回路,就是因爲(wèi)在該回路中,應(yīng)該選用卸荷溢流閥作卸荷閥,而選用了一般外控順序閥作卸荷閥,從而導(dǎo)緻液壓泵出口壓力時(shí)高時(shí)低,造成回路功耗大、油溫高,液壓系統(tǒng)不能正常工作。
順序閥職能符號(hào)與溢流閥和減壓閥的區(qū)別如圖5所示。
