MAC電磁閥從原理上分為三大類:電磁閥
1)MAC直動式電磁閥:
原理:通電時,電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起,閥門打開;斷電時,電磁力消失,彈簧把關(guān)閉件壓在閥座上,閥門關(guān)閉。 MAC直動式電磁閥特點:在真空、負壓、零壓時能正常工作,但通徑一般不超過25mm。
2)MAC分步直動式電磁閥:
原理:它是一種直動和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒有壓差時,通電后,電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起,閥門打開。當(dāng)入口與出口達到啟動壓差時,通電后,電磁力先導(dǎo)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(dǎo)閥利用彈簧力或介質(zhì)壓力推動關(guān)閉件,向下移動,使閥門關(guān)閉。 MAC分步直動式電磁閥特點: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。
3)MAC先導(dǎo)式電磁閥:
原理:通電時,電磁力把先導(dǎo)孔打開,上腔室壓力迅速下降,在關(guān)MAC電磁閥閉件周圍形成上低下高的壓差,流體壓力推動關(guān)閉件向上移動,閥門打開;斷電時,彈簧力把先導(dǎo)孔關(guān)閉,入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差,流體壓力推動關(guān)閉件向下移動,關(guān)閉閥門。
