工作原理

主要分類
1、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、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。
3、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)按照(zhao)功能分類：水用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、消(xiao)防電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、氣體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、液(ye)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、液(ye)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)、防爆(bao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)等。

派克電磁閥選型原則：
安全性：
1、腐蝕性介質：宜選用塑料王電磁閥和全不銹鋼；對于強腐蝕的介 質必須選用隔離膜片式。中性介質，也宜選用銅合金為閥殼材料的電磁閥，否則，閥殼中常有銹屑脫落，尤其是動作不頻繁的場合。氨用閥則不能采用銅材。
2、爆炸性環境：必須選用相應防爆等級產品，露天安裝或粉塵多場合應選用防水，防塵品種。
3、電磁閥公稱壓力應超過管內zui高工作壓力。
適用性：
1、介質特性
1）質氣，液態或混合狀態分別選用不同品種的電磁閥；
2）介質溫度不同規格產品，否則線圈會燒掉，密封件老化，嚴重影響壽命命；
3）介質粘度，通常在50cSt以下。若超過此值，通徑大于15mm時，用多功能電磁閥；通徑小于15mm時，用高粘度電磁閥。
4）介質清潔度不高時都應在電磁閥前配裝反沖過濾閥，壓力低時，可選用直動膜片式電磁閥；
5）介質若是定向流通，且不允許倒流，需用雙向流通；
6）介質溫度應選在電磁閥允許范圍之內。
2、管道參數
1）根據介質流向要求及管道連接方式選擇閥門通口及型號；
2）根據流量和閥門Kv值選定公稱通徑，也可選同管道內徑；
3）工(gong)作壓差(cha)：zui低工(gong)作壓差(cha)在0.04Mpa以上是可(ke)選用間接先導(dao)式(shi)；zui低工(gong)作壓差(cha)接近或小于零的必須(xu)選用直(zhi)動(dong)式(shi)或分步直(zhi)接式(shi)。
