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

美國ASCO電磁閥通電時,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,關(guān)閉。特點:在真空、負壓、零壓時能正常工作,但通徑一般不超過25mm。

阿斯卡電磁閥提示:
1,如果電磁閥的出口壓力大于進口壓力,電磁閥將方向?qū)?,此時應安裝止回閥。
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),請安裝過濾網(wǎng)或過濾閥:30-60目/in。12600002,400325-142,35500192,8210G013,43004184,

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