伊頓威格士DG4V36CMUH760電磁閥按原理分三大類：

1、直動式電磁閥

原(yuan)理：通電(dian)時，電(dian)磁線圈產生(sheng)電(dian)磁力把關閉(bi)件從閥(fa)(fa)座(zuo)上提起，閥(fa)(fa)門打開(kai)；斷電(dian)時，電(dian)磁力消失，彈簧把關閉(bi)件壓在(zai)閥(fa)(fa)座(zuo)上，閥(fa)(fa)門關閉(bi)。

特點(dian)：在(zai)真空(kong)、負壓(ya)、零壓(ya)時能正(zheng)常(chang)工作，但(dan)通徑一般不超過25mm。

2、分步直動式

原(yuan)理：它是一(yi)種(zhong)直(zhi)動(dong)和先(xian)導(dao)(dao)式相結(jie)合的原(yuan)理，當入口(kou)(kou)(kou)與出口(kou)(kou)(kou)沒有壓(ya)(ya)差時，通電(dian)(dian)后，電(dian)(dian)磁力(li)(li)直(zhi)接把(ba)先(xian)導(dao)(dao)小閥(fa)和主(zhu)閥(fa)關閉(bi)(bi)件依(yi)次向上提起，閥(fa)門(men)打開。當入口(kou)(kou)(kou)與出口(kou)(kou)(kou)達到啟動(dong)壓(ya)(ya)差時，通電(dian)(dian)后，電(dian)(dian)磁力(li)(li)先(xian)導(dao)(dao)小閥(fa)，主(zhu)閥(fa)下(xia)腔(qiang)壓(ya)(ya)力(li)(li)上升(sheng)，上腔(qiang)壓(ya)(ya)力(li)(li)下(xia)降，從(cong)而(er)利用(yong)壓(ya)(ya)差把(ba)主(zhu)閥(fa)向上推開；斷電(dian)(dian)時，先(xian)導(dao)(dao)閥(fa)利用(yong)彈簧(huang)力(li)(li)或介質壓(ya)(ya)力(li)(li)推動(dong)關閉(bi)(bi)件，向下(xia)移動(dong)，使閥(fa)門(men)關閉(bi)(bi)。

特(te)點：在(zai)零壓差或真空、高壓時亦能可*動作，但功率較(jiao)大，要求必須水平安裝。

3、先導式電磁閥

原理(li)：通電(dian)時(shi)，電(dian)磁力(li)把先(xian)導孔(kong)打開(kai)，上腔(qiang)室壓(ya)力(li)迅(xun)速下(xia)降，在關(guan) 閉件(jian)周圍形成上低下(xia)高的壓(ya)差(cha)，流體壓(ya)力(li)推(tui)動(dong)關(guan)閉件(jian)向上移動(dong)，閥門打開(kai)；斷電(dian)時(shi)，彈簧(huang)力(li)把先(xian)導孔(kong)關(guan)閉，入口壓(ya)力(li)通過旁通孔(kong)迅(xun)速腔(qiang)室在關(guan)閥件(jian)周圍形成下(xia)低上高的壓(ya)差(cha)，流體壓(ya)力(li)推(tui)動(dong)關(guan)閉件(jian)向下(xia)移動(dong)，關(guan)閉閥門。

特點：流(liu)(liu)體(ti)壓(ya)力范圍上(shang)限較高，可(ke)任(ren)意安裝（需定(ding)制）但必須滿足流(liu)(liu)體(ti)壓(ya)差條(tiao)件。

2、電磁閥從閥結(jie)(jie)構(gou)和材料上(shang)的(de)不同與原(yuan)理(li)上(shang)的(de)區別，分為六個分支小(xiao)類：直(zhi)(zhi)動(dong)(dong)膜片結(jie)(jie)構(gou)、分步直(zhi)(zhi)動(dong)(dong)膜片結(jie)(jie)構(gou)、先導(dao)膜片結(jie)(jie)構(gou)、直(zhi)(zhi)動(dong)(dong)活塞結(jie)(jie)構(gou)、分步直(zhi)(zhi)動(dong)(dong)活塞結(jie)(jie)構(gou)、先導(dao)活塞結(jie)(jie)構(gou)。

3、電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)按照功能分類(lei)：水用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、低溫(wen)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、燃(ran)氣電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、消防電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、氣體(ti)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、液(ye)體(ti)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、直(zhi)流電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、高壓(ya)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、防爆電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)等。
