????按用途分為溢流閥、減壓閥和順序閥。(1)溢流閥：能控制液壓系統(tǒng)在達到調(diào)定壓力時保持恒定狀態(tài)。用於過載保護的溢流閥稱為安全閥。當系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時，閥口會打開而溢流，以保證系統(tǒng)的安全。(2)減壓閥：能控制分支回路得到比主回路油壓低的穩(wěn)定壓力。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：能使一個執(zhí)行元件(如液壓缸、液壓馬達等)動作以后，再按順序使其他執(zhí)行元件動作。油泵產(chǎn)生的壓力先推動液壓缸1運動，同時通過順序閥的進油口作用在面積A?上，當液壓缸1運動完全成后，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，閥芯上升使進油口與出油口相通，使液壓缸2運動。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)生的局部阻力對流量進行調(diào)節(jié)，從而控制執(zhí)行元件的運動速度。

????流量控制閥

????按用途分為?5種。(1)節(jié)流閥：在調(diào)定節(jié)流口面積后，能使載荷壓力變化不大和運動均勻性要求不高的執(zhí)行元件的運動速度基本上保持穩(wěn)定。(2)調(diào)速閥：在載荷壓力變化時能保持節(jié)流閥的進出口壓差為定值。

這樣，在節(jié)流口面積調(diào)定以后，不論載荷壓力如何變化，調(diào)速閥都能保持通過節(jié)流閥的流量不變，從而使執(zhí)行元件的運動速度穩(wěn)定。(3)分流閥：不論載荷大小，能使同一油源的兩個執(zhí)行元件得到相等流量的為等量分流閥或同步閥；得到按比例分配流量的為比例分流閥。(4)集流閥：作用與分流閥相反，使流入集流閥的流量按比例分配。(5)分流集流閥：兼具分流閥和集流閥兩種功能。
