詳細(xì)介紹
美國(guó)ASCO電磁閥其結(jié)構(gòu)主要由導(dǎo)閥和主閥組成,主閥采用橡膠密封結(jié)構(gòu)。 常位時(shí),活動(dòng)鐵芯封住導(dǎo)閥口,閥腔內(nèi)壓力平衡,主閥口封閥。當(dāng)線圈通電時(shí),產(chǎn)生電磁力將活動(dòng)鐵芯吸上,主閥腔內(nèi)的介質(zhì)自導(dǎo)閥口外泄,以至產(chǎn)生壓力差,膜片或閥杯被迅速托起,主閥口開(kāi)啟,閥便呈通路了。 當(dāng)線圈斷電,磁場(chǎng)消失,活動(dòng)鐵芯復(fù)位,封閉導(dǎo)閥口,導(dǎo)閥和主閥腔內(nèi)壓力平衡后,閥又呈關(guān)閉常位。

阿斯卡電磁閥提示:
1,如果電磁閥的出口壓力大于進(jìn)口壓力,電磁閥將方向?qū)?,此時(shí)應(yīng)安裝止回閥。
2,電磁閥去掉線圈,反向安裝,可作止回閥使用。
3,如果介質(zhì)有雜質(zhì),請(qǐng)安裝過(guò)濾網(wǎng)或過(guò)濾閥:30-60目/in。12600002,400325-142,35500192,8210G013,43004184,

ASCO電磁閥常閉式--當(dāng)入口與出口沒(méi)有壓差時(shí),通電后電磁力直接打開(kāi)先導(dǎo)孔連接主閥活塞依次向上提起,閥門(mén)打開(kāi);當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后,電磁力先打開(kāi)先導(dǎo)孔,主閥活塞上腔壓力下降,從而利用壓差和電磁力拉動(dòng)主活塞,閥口打開(kāi);斷電時(shí),靠彈簧復(fù)位關(guān)閉先導(dǎo)孔,主活塞上腔增壓,推動(dòng)主活塞向下移動(dòng),閥關(guān)閉。常開(kāi)式與常閉式相反。
