進(jìn)口真空電磁閥
進(jìn)口真空電磁閥產(chǎn)品概述
美國(guó)沃克(WORK)進(jìn)口真空電磁閥是安裝在機(jī)械式真空泵上的閥門。閥門與泵接在同一電源上,泵的開啟與停止直接控制了閥的開啟與關(guān)閉。當(dāng)泵停止工作或電源突然中斷時(shí),閥能自動(dòng)將真空系統(tǒng)封閉,并將大氣通過泵的進(jìn)氣口充入泵腔,避免泵油返流污染真空系統(tǒng)。真空電磁閥適用的工作介質(zhì)為空氣及非腐蝕性氣體。
進(jìn)口真空電磁閥工作原理
常閉:當(dāng)線圈通電時(shí),先導(dǎo)閥芯吸合,先導(dǎo)孔打開,閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動(dòng),電磁閥打開。
當(dāng)線圈斷電時(shí),先導(dǎo)閥芯靠彈簧復(fù)位,先導(dǎo)孔關(guān)閉,閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力,電磁閥關(guān)閉。
