液壓閥 方向控制閥 壓力控制 流星控制閥 方向控制 方向控制閥控制液壓系統(tǒng)中油液流動的方向或液流的通與斷單向閥換向煙雙向液壓鎖單向閥二、換向闊工作原理利用閥芯和闊體的相對運(yùn)動使油路接通、關(guān)斷或變換油流的方向，從而實(shí)現(xiàn)液壓執(zhí)行元件及其驅(qū)動機(jī)構(gòu)的啟動、停止或變換運(yùn)動方向

分類

按操作方式分:手動換向闊、機(jī)動換向閥(亦稱行程閥)、電磁換向閥、液動換向閥和電液換向閥等按閥芯工作時在閥體中所處的位置和換向閥所控制的通路數(shù)不同分:位通換向閥、二位二通換向闊、二位四通換向閥、二位四通換向閥等按閥的安裝方式分:管式(亦稱螺紋式)換向閥、板式換向閥和法蘭式換向閥等按閥的結(jié)構(gòu)形式分:滑閥式換向閥、轉(zhuǎn)閥式換向閥和錐閥式換向閥等換向閥的圖形符號方格數(shù)即"位"數(shù)，三格即三位箭頭表示兩油路連通，但不表示流向。表示油路不通。在方格內(nèi)，箭頭或"符號與方格的交點(diǎn)數(shù)為油路的通路.液控單向閥

功用

-允許液流正向流動，

反向是否允許流動由控制口X控制

工作原理

當(dāng)控制油口X不通壓力油時，油液只能從A-B

當(dāng)控制油口X通壓力油時，正、反向的油液均可自由通過
