2W黃銅電磁閥

• 電磁閥的工作原理(li)：

電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)里有(you)(you)密(mi)閉的(de)腔(qiang)，在的(de)不(bu)同(tong)位(wei)置開(kai)(kai)有(you)(you)通孔，每個孔都通向(xiang)不(bu)同(tong)的(de)油(you)管，腔(qiang)中間(jian)是(shi)閥(fa)(fa)，兩(liang)面是(shi)兩(liang)塊電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)鐵(tie)，哪面的(de)磁(ci)(ci)(ci)(ci)鐵(tie)線圈通電(dian)(dian)(dian)(dian)(dian)閥(fa)(fa)體就會被吸(xi)引到哪邊，通過控制閥(fa)(fa)體的(de)移動(dong)(dong)(dong)(dong)(dong)來檔住或漏(lou)出(chu)不(bu)同(tong)的(de)排(pai)油(you)的(de)孔，而(er)進油(you)孔是(shi)常開(kai)(kai)的(de)，液壓油(you)就會進入不(bu)同(tong)的(de)排(pai)油(you)管，然(ran)后通過油(you)的(de)壓力來推動(dong)(dong)(dong)(dong)(dong)油(you)剛的(de)活塞(sai)，活塞(sai)又(you)帶動(dong)(dong)(dong)(dong)(dong)活塞(sai)桿，活塞(sai)竿帶動(dong)(dong)(dong)(dong)(dong)機(ji)械裝置動(dong)(dong)(dong)(dong)(dong)。這樣通過控制電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)鐵(tie)的(de)電(dian)(dian)(dian)(dian)(dian)流就控制了機(ji)械運動(dong)(dong)(dong)(dong)(dong)。縱(zong)觀國(guo)內(nei)外電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)，到目前為止，從(cong)動(dong)(dong)(dong)(dong)(dong)作方(fang)式(shi)(shi)(shi)(shi)上可(ke)分為三大(da)類即：直動(dong)(dong)(dong)(dong)(dong)式(shi)(shi)(shi)(shi)、反(fan)(fan)沖(chong)式(shi)(shi)(shi)(shi)、先(xian)導(dao)式(shi)(shi)(shi)(shi)，而(er)從(cong)閥(fa)(fa)瓣結構和材料(liao)上的(de)不(bu)同(tong)以及原理(li)上的(de)區別反(fan)(fan)沖(chong)式(shi)(shi)(shi)(shi)又(you)可(ke)分為：膜(mo)片(pian)式(shi)(shi)(shi)(shi)反(fan)(fan)沖(chong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、活塞(sai)式(shi)(shi)(shi)(shi)反(fan)(fan)沖(chong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)；先(xian)導(dao)式(shi)(shi)(shi)(shi)又(you)可(ke)分為：先(xian)導(dao)式(shi)(shi)(shi)(shi)膜(mo)片(pian)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、先(xian)導(dao)式(shi)(shi)(shi)(shi)活塞(sai)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)；從(cong)閥(fa)(fa)座(zuo)及密(mi)封(feng)材料(liao)上分又(you)可(ke)分為：軟密(mi)封(feng)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、鋼性密(mi)封(feng)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、半鋼性密(mi)封(feng)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)。

• 產品特點：
  1、選用塑封線(xian)圈可(ke)提(ti)高該產(chan)品在眾多環境下的安全(quan)使用。
  2、采用(yong)直(zhi)動式(shi)膜片(pian)結構無壓力啟動，擴充了其使用(yong)領域。
  3、采用平(ping)板式膜片結構(gou)啟閉可靠，并增(zeng)強了該產(chan)品(pin)的(de)使(shi)用壽(shou)命。
• 結構形式(shi)：

2W黃銅電磁閥通電時，連桿被提升，帶動轉軸轉動，副閥打開。由于副閥被開啟，主閥閥杯上部的壓力流體被排出，因此主閥閥杯下部的壓力比上部高，這樣下部的壓力將主閥閥杯向上推開。主閥被打開后，上下壓力相等，閥杯在電磁力、上下壓力作用下，置于平衡狀態，閥門開通。斷電時在銜鐵自重及返回彈簧作用下，關下副閥，副閥關閉后，隨之主閥閥杯上部的壓力升高而將主閥閥杯壓下，達到斷流密封作用，閥門關閉。
