功能順序閥的功能在于利用液壓系統(tǒng)中的壓力變化，控制油路通斷來(lái)控制多個(gè)執(zhí)行元件的順序動(dòng)作。

　　特點(diǎn)按照結(jié)構(gòu)，順序閥也有直動(dòng)式和先導(dǎo)式兩種。直動(dòng)式順序閥結(jié)構(gòu)簡(jiǎn)單，動(dòng)作靈敏，但調(diào)定壓力較低，較高壓力時(shí)宜采用先導(dǎo)式順序閥。根據(jù)控制壓力來(lái)源的不同，順序閥有內(nèi)控式和外控式之分，請(qǐng)注意兩者圖形符號(hào)的區(qū)別。內(nèi)控式順序閥在進(jìn)油路壓力達(dá)到設(shè)定壓力之前，閥口一直是關(guān)閉的，達(dá)到設(shè)定壓力后閥口打開(kāi)，使壓力油進(jìn)入油路;外控式順序閥閥口的開(kāi)閉與油路進(jìn)口壓力無(wú)關(guān)，僅取決于控制油路壓力的大小。

　　順序閥與溢流閥的主要區(qū)別為：

　　(1)順序閥只有開(kāi)啟和切斷兩種狀態(tài)，不象溢流閥那樣有自動(dòng)穩(wěn)壓調(diào)節(jié)作用;

　　(2)順序閥進(jìn)出油口都是壓力油路，所以它的泄油口必須單獨(dú)引回油箱，而溢流閥則和出口合并一同流回油箱。

　　(3)順序閥的進(jìn)、出油口一經(jīng)接通，油液通過(guò)該閥的壓力損失較小，而溢流閥處于溢流狀態(tài)時(shí)，壓力損失一般較大。
