主要分類

1、電磁閥從原理上(shang)分(fen)為三大類(lei)：

直動式電磁閥

原理：通電(dian)時，電(dian)磁線圈產生電(dian)磁力把(ba)關閉(bi)件(jian)從(cong)閥(fa)座上提起(qi)，閥(fa)門打開(kai)；斷電(dian)時，電(dian)磁力消失，彈簧把(ba)關閉(bi)件(jian)壓在閥(fa)座上，閥(fa)門關閉(bi)。

特點(dian)：在(zai)真空、負壓(ya)、零壓(ya)時能正常工作，但通(tong)徑一般不(bu)超過(guo)25mm。

分步直動式電磁閥

原理(li)：它(ta)是(shi)一種直(zhi)動(dong)和先(xian)(xian)導(dao)式相結合的原理(li)，當入口與(yu)出(chu)口沒有壓差時，通(tong)電后，電磁力(li)直(zhi)接把先(xian)(xian)導(dao)小閥(fa)(fa)(fa)和主閥(fa)(fa)(fa)關(guan)閉件(jian)依次(ci)向(xiang)上(shang)提起，閥(fa)(fa)(fa)門打開。當入口與(yu)出(chu)口達到啟動(dong)壓差時，通(tong)電后，電磁力(li)先(xian)(xian)導(dao)小閥(fa)(fa)(fa)，主閥(fa)(fa)(fa)下(xia)(xia)腔壓力(li)上(shang)升(sheng)，上(shang)腔壓力(li)下(xia)(xia)降，從(cong)而(er)利(li)用(yong)壓差把主閥(fa)(fa)(fa)向(xiang)上(shang)推開；斷電時，先(xian)(xian)導(dao)閥(fa)(fa)(fa)利(li)用(yong)彈(dan)簧力(li)或(huo)介質壓力(li)推動(dong)關(guan)閉件(jian)，向(xiang)下(xia)(xia)移動(dong)，使(shi)閥(fa)(fa)(fa)門關(guan)閉。

特點：在零壓(ya)差或真空、高壓(ya)時亦能(neng)可(ke)*動作，但功率較大，要(yao)求必須(xu)水平(ping)安(an)裝。

先導式電磁閥

原理：通(tong)電(dian)(dian)時，電(dian)(dian)磁(ci)力(li)(li)把(ba)先導(dao)孔(kong)打開，上(shang)腔室(shi)壓(ya)力(li)(li)迅速(su)(su)下(xia)降，在關(guan)(guan) 閉(bi)件(jian)周圍(wei)(wei)形(xing)成上(shang)低下(xia)高的壓(ya)差，流(liu)(liu)體(ti)(ti)壓(ya)力(li)(li)推動關(guan)(guan)閉(bi)件(jian)向上(shang)移動，閥門打開；斷電(dian)(dian)時，彈(dan)簧力(li)(li)把(ba)先導(dao)孔(kong)關(guan)(guan)閉(bi)，入(ru)口壓(ya)力(li)(li)通(tong)過旁(pang)通(tong)孔(kong)迅速(su)(su)腔室(shi)在關(guan)(guan)閥件(jian)周圍(wei)(wei)形(xing)成下(xia)低上(shang)高的壓(ya)差，流(liu)(liu)體(ti)(ti)壓(ya)力(li)(li)推動關(guan)(guan)閉(bi)件(jian)向下(xia)移動，關(guan)(guan)閉(bi)閥門。

特點：流體壓力范圍上限較(jiao)高，可任(ren)意安裝（需定制(zhi)）但(dan)必(bi)須滿(man)足流體壓差條(tiao)件。

2、電(dian)磁(ci)閥(fa)從閥(fa)結(jie)(jie)構(gou)和材料上(shang)(shang)的(de)不同與原理(li)上(shang)(shang)的(de)區別，分(fen)為六個分(fen)支小類：直(zhi)(zhi)動(dong)膜(mo)片結(jie)(jie)構(gou)、分(fen)步直(zhi)(zhi)動(dong)膜(mo)片結(jie)(jie)構(gou)、先(xian)導膜(mo)片結(jie)(jie)構(gou)、直(zhi)(zhi)動(dong)活塞結(jie)(jie)構(gou)、分(fen)步直(zhi)(zhi)動(dong)活塞結(jie)(jie)構(gou)、先(xian)導活塞結(jie)(jie)構(gou)。

3、電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)按照功能(neng)分類：水用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、蒸汽(qi)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、低溫電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、燃氣(qi)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、消防電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、氨用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、氣(qi)體(ti)(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、液(ye)體(ti)(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、微型電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa) 常開電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、油用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、直流電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、高壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、防爆(bao)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)等。
