二、美國威格士VICKERS電磁閥敘述

1、威格士VICKERS電磁閥從原理上分為三大類：
直動式電磁閥
原理：通電時，電磁線圈產生電磁力把關閉件從閥座上提起，閥門打開；斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。
特點：在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。
分步直動式電磁閥
原理：它是一種直動和先導式相結合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把先導小閥和主閥關閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力先導小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，先導閥利用彈簧力或介質壓力推動關閉件，向下移動，使閥門關閉。
特點：在零壓差或真空、高壓時亦能可*動作，但功率較大，要求必須水平安裝。
先導式電磁閥
原理：通電時，電磁力把先導孔打開，上腔室壓力迅速下降，在關 閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把先導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。
特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。
2、威格士VICKERS電磁閥從閥結構和材料上的不同與原理上的區別，分為六個分支小類：直動膜片結構、分步直動膜片結構、先導膜片結構、直動活塞結構、分步直動活塞結構、先導活塞結構。
