電(dian)(dian)(dian)(dian)液(ye)比(bi)(bi)例(li)(li)(li)閥是閥內比(bi)(bi)例(li)(li)(li)電(dian)(dian)(dian)(dian)磁鐵輸(shu)(shu)入(ru)電(dian)(dian)(dian)(dian)壓(ya)信號產生相(xiang)應(ying)動(dong)作(zuo)(zuo)，使(shi)工(gong)作(zuo)(zuo)閥閥芯產生位移，閥口(kou)尺寸發生改變(bian)并(bing)以(yi)(yi)此完成與輸(shu)(shu)入(ru)電(dian)(dian)(dian)(dian)壓(ya)成比(bi)(bi)例(li)(li)(li)壓(ya)力(li)(li)、流(liu)量輸(shu)(shu)出元件。閥芯位移也可以(yi)(yi)以(yi)(yi)機械(xie)、液(ye)壓(ya)或電(dian)(dian)(dian)(dian)形式(shi)進行反饋。電(dian)(dian)(dian)(dian)液(ye)比(bi)(bi)例(li)(li)(li)閥具有(you)形式(shi)種(zhong)類多樣、容易組成使(shi)用(yong)(yong)電(dian)(dian)(dian)(dian)氣及計算機控(kong)(kong)制(zhi)各種(zhong)電(dian)(dian)(dian)(dian)液(ye)系統、控(kong)(kong)制(zhi)精(jing)度高、安裝使(shi)用(yong)(yong)靈活以(yi)(yi)及抗污染能(neng)(neng)力(li)(li)強等多方面(mian)優點，應(ying)用(yong)(yong)領域日益拓寬。研發生產插裝式(shi)比(bi)(bi)例(li)(li)(li)閥和(he)比(bi)(bi)例(li)(li)(li)多路閥充分考慮到工(gong)程機械(xie)使(shi)用(yong)(yong)特點，具有(you)先導(dao)控(kong)(kong)制(zhi)、負載傳(chuan)感和(he)壓(ya)力(li)(li)補償等功(gong)能(neng)(neng)。它出現(xian)(xian)對(dui)移動(dong)式(shi)液(ye)壓(ya)機械(xie)整(zheng)體技術水(shui)平提升具有(you)重要(yao)意義。特別是電(dian)(dian)(dian)(dian)控(kong)(kong)先導(dao)操作(zuo)(zuo)、無線(xian)遙控(kong)(kong)和(he)有(you)線(xian)遙控(kong)(kong)操作(zuo)(zuo)等方面(mian)展現(xian)(xian)了其良好(hao)應(ying)用(yong)(yong)前景。

輸(shu)(shu)入信號增大，供(gong)氣用電磁閥(fa)先導(dao)閥(fa)1換向，而排氣用電磁先導(dao)閥(fa)7處于復位(wei)狀態，則(ze)供(gong)氣壓(ya)力(li)從SUP口通過閥(fa)1進(jin)入先導(dao)室(shi)5，先導(dao)室(shi)壓(ya)力(li)上升，氣壓(ya)力(li)作用在(zai)膜(mo)片(pian)(pian)2的(de)(de)上方，則(ze)和膜(mo)片(pian)(pian)2相連的(de)(de)供(gong)氣閥(fa)芯(xin)4便開(kai)啟，排氣閥(fa)芯(xin)3關(guan)閉，產生輸(shu)(shu)出壓(ya)力(li)。此輸(shu)(shu)出壓(ya)力(li)通過壓(ya)力(li)傳感器6反饋(kui)至控制回(hui)路8。在(zai)這里，與(yu)目標值進(jin)行快(kuai)速比較修正，直到輸(shu)(shu)出壓(ya)力(li)與(yu)輸(shu)(shu)入信號成(cheng)一定比例為止，從而得到輸(shu)(shu)出壓(ya)力(li)與(yu)輸(shu)(shu)入信號的(de)(de)變(bian)化(hua)(hua)成(cheng)比例的(de)(de)變(bian)化(hua)(hua)。由于沒有噴嘴擋板機構，故閥(fa)對雜質(zhi)不敏(min)感，可(ke)靠性(xing)高。
