BOSCH博世液壓閥是一種用壓力油操作的自動化元件,它受配壓閥壓力油的控制,通常與電磁配壓閥組合使用,可用于遠(yuǎn)距離控制水電站油、氣、水管路系統(tǒng)的通斷。常用于夾緊、控制、潤滑等油路。有直動型與先導(dǎo)型之分,多用先導(dǎo)型。
BOSCH博世液壓閥液壓傳動中用來控制液體壓力﹑流量和方向的元件。其中控制壓力的稱為壓力控制閥,控制流量的稱為流量控制閥,控制通﹑斷和流向的稱為方向控制閥。編輯本段壓力控制閥按用途分為溢流閥﹑減壓閥和順序閥。(1)溢流閥:能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過載保護(hù)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(shí),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(gè)執(zhí)行元件(如液壓缸﹑液壓馬達(dá)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(yùn)動,同時(shí)通過順序閥的進(jìn)油口作用在面積A 上,當(dāng)液壓缸1運(yùn)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(jìn)油口與出油口相通,使液壓缸2運(yùn)動。
