電動空氣控制閥 DN32/DN48 

產(chan)品詳情

電動空氣控制閥(fa)是(shi)專用為WFB系列無密(mi)封(feng)自(zi)(zi)控自(zi)(zi)吸泵(beng)或其它型號無密(mi)封(feng)自(zi)(zi)吸泵(beng)設計專用的，是(shi)自(zi)(zi)吸泵(beng)的重(zhong)要組成部分之一。

    電動空氣(qi)控(kong)制閥(fa)的作用：

 ;   電(dian)動空(kong)氣(qi)(qi)控(kong)(kong)制閥作為自(zi)吸(xi)(xi)(xi)泵(beng)的(de)組(zu)成部(bu)分之一(yi)裝(zhuang)在(zai)吸(xi)(xi)(xi)液(ye)口(kou)(kou)的(de)進氣(qi)(qi)管(guan)上(shang)，啟(qi)泵(beng)時(shi)電(dian)控(kong)(kong)閥密(mi)閉泵(beng)體吸(xi)(xi)(xi)液(ye)管(guan)上(shang)的(de)進氣(qi)(qi)口(kou)(kou)，使自(zi)吸(xi)(xi)(xi)泵(beng)泵(beng)腔內(nei)形成真(zhen)空(kong)，完(wan)成自(zi)吸(xi)(xi)(xi)全過(guo)程。停泵(beng)時(shi)電(dian)控(kong)(kong)閥開啟(qi)，空(kong)氣(qi)(qi)從密(mi)閉口(kou)(kou)進入(ru)水泵(beng)液(ye)管(guan)內(nei)迅速(su)隔離吸(xi)(xi)(xi)液(ye)管(guan)內(nei)共流的(de)介質(zhi)，確保(bao)(bao)泵(beng)腔的(de)介質(zhi)不隨吸(xi)(xi)(xi)液(ye)管(guan)腔內(nei)的(de)介質(zhi)回落到(dao)吸(xi)(xi)(xi)液(ye)池中，以達到(dao)消(xiao)除(chu)虹(hong)吸(xi)(xi)(xi)的(de)目的(de)，確保(bao)(bao)自(zi)吸(xi)(xi)(xi)泵(beng)二次自(zi)吸(xi)(xi)(xi)時(shi)正常自(zi)吸(xi)(xi)(xi)及運行。

    電動空氣(qi)控(kong)制閥的工作原理：

    電(dian)(dian)(dian)(dian)(dian)動(dong)空氣控(kong)制(zhi)閥(fa)接(jie)線(xian)與(yu)水泵(beng)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)源并(bing)聯(lian)(三相三線(xian)380V電(dian)(dian)(dian)(dian)(dian)源任意兩(liang)線(xian)，電(dian)(dian)(dian)(dian)(dian)壓為380V)，自吸(xi)泵(beng)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)啟(qi)動(dong)時(shi)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)同(tong)時(shi)同(tong)步通電(dian)(dian)(dian)(dian)(dian)啟(qi)動(dong)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)鐵芯(xin)吸(xi)合銜鐵時(shi)帶動(dong)彈性架(jia)(jia)下移，驅動(dong)閥(fa)芯(xin)活塞桿向活塞缸體(ti)底(di)部密(mi)封墊壓緊，實現密(mi)封，關(guan)閉吸(xi)液管上進氣口通氣孔，使自吸(xi)泵(beng)開始(shi)自吸(xi)并(bing)進入正常運行(xing)狀態。當停(ting)電(dian)(dian)(dian)(dian)(dian)使電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)斷電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)線(xian)圈同(tong)時(shi)斷電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)鐵芯(xin)的(de)磁(ci)(ci)力消失，彈性架(jia)(jia)受壓縮彈簧反(fan)作用上移復位，帶動(dong)閥(fa)芯(xin)桿活塞離(li)開活塞缸底(di)，開啟(qi)通氣孔。使空氣進入吸(xi)液管腔，使泵(beng)腔內的(de)介(jie)質(zhi)與(yu)吸(xi)液管內的(de)介(jie)質(zhi)隔離(li)，消除虹吸(xi)，確保(bao)自吸(xi)泵(beng)泵(beng)腔介(jie)質(zhi)貯量，以供下次啟(qi)泵(beng)時(shi)自吸(xi)及(ji)正常運行(xing)。
