電動(dong)空氣控制閥(fa)是(shi)專用(yong)為WFB系列(lie)無密封自(zi)(zi)控自(zi)(zi)吸泵或其(qi)它(ta)型號(hao)無密封自(zi)(zi)吸泵設計專用(yong)的(de)，是(shi)自(zi)(zi)吸泵的(de)重要組成部分(fen)之一。

    電動空氣控制閥的作用：

     電(dian)動空(kong)氣(qi)控制閥作為自(zi)吸(xi)(xi)泵(beng)(beng)的(de)組(zu)成部分(fen)之一(yi)裝在吸(xi)(xi)液(ye)口的(de)進(jin)氣(qi)管上，啟泵(beng)(beng)時電(dian)控閥密閉泵(beng)(beng)體吸(xi)(xi)液(ye)管上的(de)進(jin)氣(qi)口，使(shi)自(zi)吸(xi)(xi)泵(beng)(beng)泵(beng)(beng)腔內形成真空(kong)，完(wan)成自(zi)吸(xi)(xi)全過(guo)程。停泵(beng)(beng)時電(dian)控閥開啟，空(kong)氣(qi)從密閉口進(jin)入水泵(beng)(beng)液(ye)管內迅速隔離吸(xi)(xi)液(ye)管內共(gong)流的(de)介(jie)質(zhi)(zhi)，確保(bao)泵(beng)(beng)腔的(de)介(jie)質(zhi)(zhi)不隨吸(xi)(xi)液(ye)管腔內的(de)介(jie)質(zhi)(zhi)回落到吸(xi)(xi)液(ye)池中，以(yi)達到消除虹(hong)吸(xi)(xi)的(de)目的(de)，確保(bao)自(zi)吸(xi)(xi)泵(beng)(beng)二次自(zi)吸(xi)(xi)時正常自(zi)吸(xi)(xi)及運行。

    電動空氣控制閥(fa)的工(gong)作(zuo)原理：

    電(dian)(dian)(dian)動空氣控制閥(fa)接線與水泵(beng)電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)源(yuan)并聯(三相(xiang)三線380V電(dian)(dian)(dian)源(yuan)任意(yi)兩線，電(dian)(dian)(dian)壓為380V)，自(zi)(zi)吸泵(beng)電(dian)(dian)(dian)機(ji)(ji)啟動時(shi)，電(dian)(dian)(dian)磁(ci)閥(fa)同(tong)(tong)時(shi)同(tong)(tong)步通電(dian)(dian)(dian)啟動，電(dian)(dian)(dian)磁(ci)鐵芯(xin)吸合銜鐵時(shi)帶動彈(dan)性(xing)架下移(yi)，驅動閥(fa)芯(xin)活(huo)塞(sai)桿(gan)向活(huo)塞(sai)缸體底部(bu)密(mi)封墊壓緊，實現密(mi)封，關(guan)閉吸液(ye)管(guan)上進氣口通氣孔，使自(zi)(zi)吸泵(beng)開(kai)(kai)(kai)始自(zi)(zi)吸并進入正常(chang)運行(xing)狀態。當(dang)停電(dian)(dian)(dian)使電(dian)(dian)(dian)機(ji)(ji)斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁(ci)閥(fa)電(dian)(dian)(dian)磁(ci)線圈同(tong)(tong)時(shi)斷電(dian)(dian)(dian)，電(dian)(dian)(dian)磁(ci)鐵芯(xin)的(de)磁(ci)力(li)消(xiao)失，彈(dan)性(xing)架受(shou)壓縮彈(dan)簧反作用上移(yi)復位，帶動閥(fa)芯(xin)桿(gan)活(huo)塞(sai)離開(kai)(kai)(kai)活(huo)塞(sai)缸底，開(kai)(kai)(kai)啟通氣孔。使空氣進入吸液(ye)管(guan)腔(qiang)，使泵(beng)腔(qiang)內的(de)介(jie)質與吸液(ye)管(guan)內的(de)介(jie)質隔(ge)離，消(xiao)除虹吸，確保自(zi)(zi)吸泵(beng)泵(beng)腔(qiang)介(jie)質貯量，以供下次啟泵(beng)時(shi)自(zi)(zi)吸及正常(chang)運行(xing)。
