減壓閥按它所控制的壓力功能不同，又可分為定值減壓閥(輸出壓力為恒定值)、定差減壓閥(輸入與輸出壓力差為定值)和定比減壓閥(輸入與輸出壓力間保持一定的比例)。(3)順序閥：能使一個(gè)執(zhí)行元件(如液壓缸、液壓馬達(dá)等)動(dòng)作以后，再按順序使其他執(zhí)行元件動(dòng)作。油泵產(chǎn)生的壓力先推動(dòng)液壓缸1運(yùn)動(dòng)，同時(shí)通過(guò)順序閥的進(jìn)油口作用在面積A 上，當(dāng)液壓缸1運(yùn)動(dòng)完全成后，壓力升高，作用在面積A 的向上推力大於彈簧的調(diào)定值后，閥芯上升使進(jìn)油口與出油口相通，使液壓缸2運(yùn)動(dòng)。流量控制閥利用調(diào)節(jié)閥芯和閥體間的節(jié)流口面積和它所產(chǎn)生的局部阻力對(duì)流量進(jìn)行調(diào)節(jié)，從而
