電動空(kong)氣控(kong)制(zhi)閥(fa)是(shi)專(zhuan)用(yong)為(wei)WFB系列無密封自(zi)(zi)控(kong)自(zi)(zi)吸泵或(huo)其它型(xing)號無密封自(zi)(zi)吸泵設計專(zhuan)用(yong)的(de)，是(shi)自(zi)(zi)吸泵的(de)重要組成部分之一。

    電(dian)動空(kong)氣控(kong)制閥的(de)作用：

    電(dian)(dian)動空氣(qi)(qi)(qi)控制閥作為自吸(xi)(xi)泵(beng)(beng)的(de)(de)組成部(bu)分之一裝在(zai)吸(xi)(xi)液(ye)口的(de)(de)進氣(qi)(qi)(qi)管(guan)上，啟泵(beng)(beng)時電(dian)(dian)控閥密閉(bi)泵(beng)(beng)體吸(xi)(xi)液(ye)管(guan)上的(de)(de)進氣(qi)(qi)(qi)口，使自吸(xi)(xi)泵(beng)(beng)泵(beng)(beng)腔內形成真空，完成自吸(xi)(xi)全過程。停泵(beng)(beng)時電(dian)(dian)控閥開啟，空氣(qi)(qi)(qi)從密閉(bi)口進入水泵(beng)(beng)液(ye)管(guan)內迅(xun)速隔離(li)吸(xi)(xi)液(ye)管(guan)內共流的(de)(de)介(jie)質(zhi)，確保泵(beng)(beng)腔的(de)(de)介(jie)質(zhi)不隨吸(xi)(xi)液(ye)管(guan)腔內的(de)(de)介(jie)質(zhi)回落到吸(xi)(xi)液(ye)池中，以(yi)達到消除虹吸(xi)(xi)的(de)(de)目的(de)(de)，確保自吸(xi)(xi)泵(beng)(beng)二次自吸(xi)(xi)時正常自吸(xi)(xi)及運(yun)行。

    電(dian)動(dong)空(kong)氣控制(zhi)閥的工作原理：

    電(dian)(dian)動空氣控制閥(fa)接(jie)線(xian)(xian)與水泵電(dian)(dian)機(ji)電(dian)(dian)源(yuan)并聯(三(san)相三(san)線(xian)(xian)380V電(dian)(dian)源(yuan)任意兩線(xian)(xian)，電(dian)(dian)壓為(wei)380V)，自(zi)吸(xi)(xi)(xi)(xi)泵電(dian)(dian)機(ji)啟(qi)動時(shi)，電(dian)(dian)磁(ci)閥(fa)同(tong)時(shi)同(tong)步通電(dian)(dian)啟(qi)動，電(dian)(dian)磁(ci)鐵芯(xin)吸(xi)(xi)(xi)(xi)合銜鐵時(shi)帶動彈(dan)(dan)性(xing)架下移，驅動閥(fa)芯(xin)活塞(sai)(sai)桿向活塞(sai)(sai)缸體底部密(mi)封(feng)(feng)墊壓緊(jin)，實現密(mi)封(feng)(feng)，關閉吸(xi)(xi)(xi)(xi)液管上進(jin)(jin)氣口通氣孔(kong)，使(shi)(shi)(shi)自(zi)吸(xi)(xi)(xi)(xi)泵開(kai)始自(zi)吸(xi)(xi)(xi)(xi)并進(jin)(jin)入正常運行狀態。當停電(dian)(dian)使(shi)(shi)(shi)電(dian)(dian)機(ji)斷電(dian)(dian)，電(dian)(dian)磁(ci)閥(fa)電(dian)(dian)磁(ci)線(xian)(xian)圈同(tong)時(shi)斷電(dian)(dian)，電(dian)(dian)磁(ci)鐵芯(xin)的磁(ci)力消(xiao)失，彈(dan)(dan)性(xing)架受壓縮彈(dan)(dan)簧(huang)反作用上移復(fu)位，帶動閥(fa)芯(xin)桿活塞(sai)(sai)離(li)開(kai)活塞(sai)(sai)缸底，開(kai)啟(qi)通氣孔(kong)。使(shi)(shi)(shi)空氣進(jin)(jin)入吸(xi)(xi)(xi)(xi)液管腔(qiang)(qiang)，使(shi)(shi)(shi)泵腔(qiang)(qiang)內的介(jie)質與吸(xi)(xi)(xi)(xi)液管內的介(jie)質隔(ge)離(li)，消(xiao)除虹吸(xi)(xi)(xi)(xi)，確(que)保自(zi)吸(xi)(xi)(xi)(xi)泵泵腔(qiang)(qiang)介(jie)質貯(zhu)量，以供下次(ci)啟(qi)泵時(shi)自(zi)吸(xi)(xi)(xi)(xi)及正常運行。
