style="text-indent:25px">減壓閥一般設(shè)在執(zhí)行元件支路接口處；減壓閥主要是用來(lái)降低液壓系統(tǒng)某一分支油路的壓力，使分支壓力比主油路壓力低且穩(wěn)定，在調(diào)定壓力的范圍內(nèi)，減壓閥也像溢流閥那樣是關(guān)閉的。但是隨著系統(tǒng)壓力的升高當(dāng)達(dá)到減壓閥調(diào)定的壓力時(shí)，減壓閥打開(kāi)，部分油液會(huì)經(jīng)過(guò)他返回油箱（此時(shí)有一定壓力的油回油箱，油箱的油溫會(huì)上升），這一支路的油壓是不會(huì)上升了。它起到對(duì)本支路的減壓與穩(wěn)壓作用，減壓閥是保持出口壓力基本不變，而溢流閥保持進(jìn)口壓力基本不變,在不工作時(shí)減壓閥進(jìn)出口壓力互通，而溢流閥進(jìn)出口不同。為了保證減壓閥出口壓力調(diào)定值恒定，它的先導(dǎo)彈簧腔需通過(guò)卸油口單獨(dú)外接回油箱。而溢流閥反之。</p><p
