PARKER派克電磁閥從原理上分為三大類: 派克直動(dòng)式電磁閥 原理:通電時(shí),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(shí),電磁力消失,彈簧把關(guān)閉件壓在閥座上,閥門關(guān)閉。 特點(diǎn):在真空、負(fù)壓、零壓時(shí)能正常工作,但通徑一般不超過25mm。 派克分步直動(dòng)式電磁閥 原理:它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒有壓差時(shí),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(dòng)壓差時(shí),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(shí),先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件,向下移動(dòng),使閥門關(guān)閉。 特點(diǎn):在零壓差或真空、高壓時(shí)亦能可*動(dòng)作,但功率較大,要求必須水平安裝。
派克先導(dǎo)式電磁閥 原理:通電時(shí),電磁力把先導(dǎo)孔打開,上腔室壓力迅速下降,在關(guān) 閉件周圍形成上低下高的壓差,流體壓力推動(dòng)關(guān)閉件向上移動(dòng),閥門打開;斷電時(shí),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(dòng)關(guān)閉件向下移動(dòng),關(guān)閉閥門。 特點(diǎn):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。 PAIKER派克電磁閥按照功能分類:水用電磁閥、蒸汽電磁閥、制冷電磁閥、低溫電磁閥、燃?xì)怆姶砰y、消防電磁閥、氨用電磁閥、氣體電磁閥、液體電磁閥、微型電磁閥、脈沖電磁閥、液壓電磁閥 常開電磁閥、油用電磁閥、直流電磁閥、高壓電磁閥、防爆電磁閥等。 PARKER防水錘電磁閥: 應(yīng)用:利用重力填充 / 排空容器材和zui小壓力為0的場(chǎng)合。 如:221G1610-2995-481865 PARKER二位二通防水錘電磁閥---先導(dǎo)型 應(yīng)用:切斷大流量、高壓液體,要求有zui小工作壓力(0.3bar)。 如:E321G3610-2995-481865
