追朔的發(fā)展史,到目前為止,外的從原理上分為三大類(即:直動式、分步童先導(dǎo)式),而從閥瓣結(jié)構(gòu)和材料上的不同與原理上的區(qū)別又分為六個分支小類(直動膜片結(jié)構(gòu)、分步重片結(jié)構(gòu)、先導(dǎo)膜式結(jié)構(gòu)、直動活塞結(jié)構(gòu)、分步直動活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu))parker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,關(guān)閉。
特點(diǎn):在真空、負(fù)壓、零壓時能正常工作,但通徑般不超過25mm。派克parker電磁閥原理
它是種直動和先導(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(dá)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,使關(guān)閉。

特點(diǎn):
在零壓差或真空、高壓時亦能可動作,但功率較大,要求必須安裝。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)閉件周圍形成上下高的壓差,流體壓力推動關(guān)閉件向上移動,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)閥件周圍形成下上高的壓差,流體壓力推動關(guān)閉件向下移動,關(guān)閉。電磁鐵通電后,連桿被提升,隨著轉(zhuǎn)軸開始轉(zhuǎn)動,這運(yùn)動作用于導(dǎo)閥而開主閥;斷電后,在銜鐵自重及返回彈簧作用下,關(guān)上導(dǎo)閥,導(dǎo)閥關(guān)閉后,靠壓差關(guān)閉主閥。
