伊頓DG4V威格士VICKERS電磁閥現貨主要依靠流經VICKERS電磁閥內(nei)介質自身的溫度(du)作(zuo)為(wei)能源來(lai)驅動其自動工作(zuo)的設(she)備，在(zai)自力式溫度(du)調節閥工作(zuo)系(xi)統中，不需要外接電源和二次儀表，它是(shi)一個(ge)獨立的儀表控制系(xi)統，所以也(ye)常被稱之為(wei)自力式控制閥。

VICKERS電磁閥（又是安全閥）的主閥按配合形式(shi)不同(tong)(tong)可分為三(san)(san)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)、二(er)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)和滑(hua)閥式(shi)三(san)(san)類(lei)。其中滑(hua)閥式(shi)結(jie)構工(gong)作壓力(li)低，控制(zhi)壓力(li)精度不高(gao)；三(san)(san)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)結(jie)構雖成熟，目前應(ying)用較(jiao)廣，但與二(er)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)式(shi)比(bi)較(jiao)，不及二(er)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)式(shi)動作靈敏，規格相同(tong)(tong)，行程相同(tong)(tong)時，二(er)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)結(jie)構的通油(you)能力(li)遠大于三(san)(san)級(ji)(ji)同(tong)(tong)心(xin)(xin)(xin)結(jie)構威格士的閥按原理分三(san)(san)大類(lei)：

1、直動式電磁閥

原理：通電(dian)(dian)(dian)時，電(dian)(dian)(dian)磁線圈(quan)產生電(dian)(dian)(dian)磁力把(ba)關(guan)閉(bi)件從閥(fa)(fa)座上提起，閥(fa)(fa)門打(da)開；斷電(dian)(dian)(dian)時，電(dian)(dian)(dian)磁力消失，彈(dan)簧把(ba)關(guan)閉(bi)件壓在閥(fa)(fa)座上，閥(fa)(fa)門關(guan)閉(bi)。

特點：在真空、負(fu)壓(ya)、零(ling)壓(ya)時能正常工(gong)作，但通徑一般不超過25mm。

2、分步直動式

原理(li)：它是一種直動和先(xian)導式(shi)相結合的原理(li)，當入口與出口沒有壓(ya)差時，通(tong)電(dian)(dian)后(hou)，電(dian)(dian)磁(ci)力(li)直接把先(xian)導小閥(fa)(fa)和主閥(fa)(fa)關閉件依(yi)次向(xiang)上(shang)提起，閥(fa)(fa)門打(da)開。當入口與出口達到啟動壓(ya)差時，通(tong)電(dian)(dian)后(hou)，電(dian)(dian)磁(ci)力(li)先(xian)導小閥(fa)(fa)，主閥(fa)(fa)下(xia)腔壓(ya)力(li)上(shang)升(sheng)，上(shang)腔壓(ya)力(li)下(xia)降，從而利用(yong)壓(ya)差把主閥(fa)(fa)向(xiang)上(shang)推開；斷電(dian)(dian)時，先(xian)導閥(fa)(fa)利用(yong)彈簧力(li)或(huo)介(jie)質壓(ya)力(li)推動關閉件，向(xiang)下(xia)移動，使閥(fa)(fa)門關閉。

特點：在零(ling)壓(ya)差(cha)或真空、高壓(ya)時亦能可*動作(zuo)，但功率(lv)較(jiao)大(da)，要求必須水(shui)平安裝。

3、先導式電磁閥

原理：通(tong)電時，電磁力(li)把先導孔(kong)打開，上(shang)腔室(shi)壓(ya)力(li)迅速(su)下(xia)降，在(zai)關(guan) 閉(bi)件(jian)(jian)周圍(wei)形成上(shang)低(di)下(xia)高的壓(ya)差(cha)(cha)，流體壓(ya)力(li)推(tui)動(dong)關(guan)閉(bi)件(jian)(jian)向(xiang)上(shang)移動(dong)，閥(fa)門打開；斷電時，彈(dan)簧力(li)把先導孔(kong)關(guan)閉(bi)，入口壓(ya)力(li)通(tong)過旁通(tong)孔(kong)迅速(su)腔室(shi)在(zai)關(guan)閥(fa)件(jian)(jian)周圍(wei)形成下(xia)低(di)上(shang)高的壓(ya)差(cha)(cha)，流體壓(ya)力(li)推(tui)動(dong)關(guan)閉(bi)件(jian)(jian)向(xiang)下(xia)移動(dong)，關(guan)閉(bi)閥(fa)門。

特點：流體壓力范圍上限較高，可任意(yi)安裝（需定制(zhi)）但必須滿(man)足流體壓差條件。

2、電磁閥(fa)從閥(fa)結(jie)(jie)構和材料上的(de)不同與(yu)原(yuan)理上的(de)區(qu)別，分(fen)為六個(ge)分(fen)支小類：直(zhi)動(dong)(dong)(dong)膜(mo)(mo)片結(jie)(jie)構、分(fen)步直(zhi)動(dong)(dong)(dong)膜(mo)(mo)片結(jie)(jie)構、先導膜(mo)(mo)片結(jie)(jie)構、直(zhi)動(dong)(dong)(dong)活塞結(jie)(jie)構、分(fen)步直(zhi)動(dong)(dong)(dong)活塞結(jie)(jie)構、先導活塞結(jie)(jie)構。

3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)按照功能(neng)分類(lei)：水(shui)用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、低(di)溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、燃氣(qi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氣(qi)體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、脈(mo)沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、油用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、高壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)等(deng)。
