先導式(WRZ)和直動式(WRH)比例換向閥 底板安裝一個閥既控制流量又控制流動方向彈簧對中,因此主閥芯無漂移閥芯臺肩壓降小閥和比列放大器配套供應(yīng)由比例電磁鐵操縱4WRZ型閥是靠比例電磁鐵控制的先導式比例換向閥,將電氣化號轉(zhuǎn)化為壓力,用來控制液壓的流量和流動方向。該閥主要由先導閥、主閥芯圓、主閥因、復位彈簧等組成。當電磁鐵日通電時,先導閩西園右移,控制油經(jīng)內(nèi)部通道從P口或經(jīng)外控口X通過先導閥國進入主閥芯右端圓并推動主閥芯左移,量與給定成比例,于是主閥芯逐漸并打開關(guān)在閥控制臺階上的V型控制溝槽,從面使P到A,B到T流通。當電磁鐵斷電叫,先導閥芯固返回起始位置,閥芯靠復位彈簧保持中位,并與先導壓力無關(guān)。手動按鈕可在電磁鐵不通電情況下,操作先導閥使主閥。
