rexroth力士樂(lè)BM6液壓閥

液壓閥是一種用壓力油操作的自動(dòng)化元件,，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。下面我給大家介紹一下液壓閥原理,。

    一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成,，即動(dòng)力元件、執(zhí)行元件,、控制元件,、無(wú)件和液壓油。動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能,，指液壓系統(tǒng)中的油泵,，它向整個(gè)液壓系統(tǒng)提供動(dòng)力,。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵和柱塞泵,。執(zhí)行元件(如液壓油缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能,，驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)?？刂圃?即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力,、流量和方向。根據(jù)控制功能的不同,，液壓閥可分為村力控制閥,、流量控制閥和方向控制閥。壓力控制閥又分為益流閥(安全閥),、減壓閥,、順序閥、壓力繼電器等;流量控制閥包括節(jié)流閥,、調(diào)整閥,、分流集流閥等;方向控制閥包括單向閥、液控單向閥,、梭閥,、換向閥等。根據(jù)控制方式不同,，液壓閥可分為開(kāi)關(guān)式控制閥,、定值控制閥和比例控制閥。輔助元件包括油箱,、濾油器,、油管及管接頭、密封圈,、壓力表,、油位油溫計(jì)等。液壓油是液壓系統(tǒng)中傳遞能量的工作介質(zhì),，有各種礦物油、乳化液和合成型液壓油等幾大類(lèi),。
