壓力控制按用途分為溢流閥﹑減壓閥和順序閥。⑴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(dāng)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。⑵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)。⑶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(dāng)液壓缸1運動*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。 力士樂液控單向閥SV20PA1-42/V 力士樂單向節(jié)流閥 R900311504 ZZ2S22-4X/V 力士樂單向節(jié)流閥 R900311503 ZZ2S22-4X/ 力士樂單向節(jié)流閥 R900311182
