力士樂比例閥的輸入壓力為零時(shí),輸出腔的壓力通過比例閥皮圈凸筋間空酸從唇口泄去高壓,同時(shí),當(dāng)比例閥芯所受的彈簧力大于向右的液壓力時(shí),比例閥彈簧將比例閥芯推回原始位置,使比例閥芯與比例閥皮圈內(nèi)孔*分離而*泄壓，此時(shí)輸入輸出壓力為零，隨著輸入壓力.增大,即左增大,使比例滑閥單向力平衡遭破壞，比例閥芯左移與比例閥皮圈產(chǎn)生間隙形成節(jié)流并混合比倒閥常見的故障為:1,輸入輸出壓力同步.2,低壓時(shí)輔人輸出壓力同步,高壓時(shí)輸入輸出壓力正常.3,低壓時(shí)輸入輸出壓力正常,高壓時(shí)輸入輸出壓力不正常.,輸入壓力為零時(shí)（不制動(dòng)時(shí)）,輸出壓力不為零等等.為混合比倒圉工作性能試驗(yàn)示意圖.試驗(yàn)時(shí),先將管內(nèi)的空氣排凈,然后分別取低,中,高三個(gè)壓力進(jìn)行試驗(yàn),輸入輔出壓力符合表1所示即為合格.表混合比例閥試驗(yàn)參數(shù)表單位，為混合比例悶常見故障和處理方法.混合比例向在拆卸維修過程中,若污染嚴(yán)重,可用變性酒精清詵,然后烘干后裝配.橡膠件裝配時(shí)表面需涂上清潔的制動(dòng)液,橡膠件不允許被機(jī)油,汽油等污染.表2混合比例閥常見故障和處理故障現(xiàn)象對制動(dòng)性的膨響常見故障處理方法輸入輸出空載制動(dòng)時(shí)汽車沒有.點(diǎn),比髑閥油封唇口,更換比例悶油封.
