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(shi)，電(dian)磁線圈產(chan)生電(dian)磁力把(ba)關(guan)(guan)閉(bi)件從閥(fa)(fa)座上提起，閥(fa)(fa)門打(da)開；斷電(dian)時(shi)，電(dian)磁力消失，彈簧把(ba)關(guan)(guan)閉(bi)件壓在閥(fa)(fa)座上，閥(fa)(fa)門關(guan)(guan)閉(bi)。

特點：在真空、負壓、零壓時能正常工作，但通徑(jing)一般不超過25mm。

2、分步直動式

原理：它(ta)是一種直動(dong)和(he)先導式相結合(he)的原理，當(dang)(dang)入口與出口沒有(you)壓(ya)差時，通電(dian)(dian)后(hou)，電(dian)(dian)磁(ci)(ci)力直接把先導小閥(fa)(fa)和(he)主閥(fa)(fa)關閉件依(yi)次向上(shang)(shang)提起，閥(fa)(fa)門(men)(men)打開。當(dang)(dang)入口與出口達到(dao)啟動(dong)壓(ya)差時，通電(dian)(dian)后(hou)，電(dian)(dian)磁(ci)(ci)力先導小閥(fa)(fa)，主閥(fa)(fa)下(xia)腔(qiang)壓(ya)力上(shang)(shang)升，上(shang)(shang)腔(qiang)壓(ya)力下(xia)降，從而利(li)用壓(ya)差把主閥(fa)(fa)向上(shang)(shang)推(tui)開；斷電(dian)(dian)時，先導閥(fa)(fa)利(li)用彈簧力或介質壓(ya)力推(tui)動(dong)關閉件，向下(xia)移動(dong)，使閥(fa)(fa)門(men)(men)關閉。

特點(dian)：在零壓差(cha)或真空、高壓時亦能可(ke)*動作，但功率較大，要求必須水平安裝。

3、先導式電磁閥

原理：通電時，電磁力(li)(li)(li)把(ba)先(xian)導孔(kong)打開，上腔(qiang)室壓(ya)力(li)(li)(li)迅速下(xia)降，在(zai)關(guan) 閉(bi)件(jian)周圍形(xing)成(cheng)上低下(xia)高(gao)(gao)的壓(ya)差(cha)，流體壓(ya)力(li)(li)(li)推動(dong)關(guan)閉(bi)件(jian)向上移(yi)(yi)動(dong)，閥(fa)(fa)門打開；斷電時，彈簧(huang)力(li)(li)(li)把(ba)先(xian)導孔(kong)關(guan)閉(bi)，入(ru)口壓(ya)力(li)(li)(li)通過旁通孔(kong)迅速腔(qiang)室在(zai)關(guan)閥(fa)(fa)件(jian)周圍形(xing)成(cheng)下(xia)低上高(gao)(gao)的壓(ya)差(cha)，流體壓(ya)力(li)(li)(li)推動(dong)關(guan)閉(bi)件(jian)向下(xia)移(yi)(yi)動(dong)，關(guan)閉(bi)閥(fa)(fa)門。

特點：流體壓力(li)范圍上限(xian)較高，可任(ren)意安裝（需(xu)定制）但(dan)必須滿足(zu)流體壓差(cha)條件(jian)。

2、電(dian)磁閥(fa)從閥(fa)結(jie)構(gou)和材料上(shang)(shang)的(de)不同與原理上(shang)(shang)的(de)區別，分為(wei)六(liu)個分支小(xiao)類(lei)：直動(dong)膜(mo)片(pian)(pian)結(jie)構(gou)、分步(bu)直動(dong)膜(mo)片(pian)(pian)結(jie)構(gou)、先(xian)導(dao)膜(mo)片(pian)(pian)結(jie)構(gou)、直動(dong)活(huo)塞(sai)(sai)結(jie)構(gou)、分步(bu)直動(dong)活(huo)塞(sai)(sai)結(jie)構(gou)、先(xian)導(dao)活(huo)塞(sai)(sai)結(jie)構(gou)。

3、電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)按(an)照(zhao)功(gong)能分類(lei)：水(shui)用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、蒸(zheng)汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、消防(fang)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氨用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氣體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、脈(mo)沖電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、油用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、防(fang)爆電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)等。
