導(dǎo)閥口開啟而導(dǎo)閥口設(shè)在主閥口上,且動(dòng)鐵芯與主閥 芯連在一起,此時(shí)主閥上腔的壓力通過導(dǎo)閥口卸荷,在壓力差和電 磁力的同時(shí)作用下使主閥芯向上運(yùn)動(dòng),開啟主閥介質(zhì)流通.當(dāng)線圈 斷電時(shí)電磁力消失,此時(shí)動(dòng)鐵芯在自重和彈簧力的作用下關(guān)閉導(dǎo)閥 孔,此時(shí)介質(zhì)在平衡孔中進(jìn)入主閥芯上腔,使上腔壓力升高,此時(shí) 在彈簧復(fù)位和壓力的作用下關(guān)閉主閥,介質(zhì)斷流.結(jié)構(gòu)合理,動(dòng)作 可靠,在零壓差時(shí)工作也可靠.

    一般電磁閥都是單向工作,因此要注 意是否有反壓差,如有安裝止回閥. 流體清潔度不高時(shí)應(yīng)在電磁閥前安裝過濾器,一般電磁 閥對(duì)介質(zhì)要求清潔度要好. 注意流量孔徑和接管口徑;電磁閥一般只有開關(guān)兩位控制;條件允 許請(qǐng)安裝旁路管,便于維修;有水錘現(xiàn)象時(shí)要定制電磁閥的開閉時(shí) 間調(diào)節(jié). 注意環(huán)境溫度對(duì)電磁閥的影響 電源電流和消耗功率應(yīng)根據(jù)輸出容量選取,電源電壓一般允許 ±10%左右,必須注意交流起動(dòng)時(shí) VA 值較高.
