電(dian)(dian)(dian)磁閥里有密(mi)閉的(de)(de)腔，在不(bu)同(tong)(tong)(tong)位置(zhi)開(kai)有通(tong)孔(kong)，每(mei)個(ge)孔(kong)都通(tong)向(xiang)不(bu)同(tong)(tong)(tong)的(de)(de)油(you)(you)(you)(you)(you)管，腔中間是(shi)閥，兩(liang)面是(shi)兩(liang)塊電(dian)(dian)(dian)磁鐵，哪面的(de)(de)磁鐵線圈(quan)通(tong)電(dian)(dian)(dian)閥體就(jiu)(jiu)會被吸引到哪邊，通(tong)過(guo)(guo)控(kong)制(zhi)閥體的(de)(de)移(yi)動來檔住或漏出不(bu)同(tong)(tong)(tong)的(de)(de)排(pai)油(you)(you)(you)(you)(you)的(de)(de)孔(kong)，而進油(you)(you)(you)(you)(you)孔(kong)是(shi)常開(kai)的(de)(de)，液壓油(you)(you)(you)(you)(you)就(jiu)(jiu)會進入(ru)不(bu)同(tong)(tong)(tong)的(de)(de)排(pai)油(you)(you)(you)(you)(you)管，然后通(tong)過(guo)(guo)油(you)(you)(you)(you)(you)的(de)(de)壓力來推動油(you)(you)(you)(you)(you)缸的(de)(de)活塞(sai)，活塞(sai)又帶動活塞(sai)桿，活塞(sai)竿帶動機械裝置(zhi)動。這樣通(tong)過(guo)(guo)控(kong)制(zhi)電(dian)(dian)(dian)磁鐵的(de)(de)電(dian)(dian)(dian)流就(jiu)(jiu)控(kong)制(zhi)了機械運動。

防爆(bao)(bao)電磁閥是把設(she)備(bei)可(ke)能點燃爆(bao)(bao)炸性氣體(ti)混(hun)合(he)物的部(bu)(bu)件全部(bu)(bu)封閉在(zai)一(yi)個(ge)外(wai)殼(ke)(ke)內(nei)，其外(wai)殼(ke)(ke)能夠承受通過(guo)外(wai)殼(ke)(ke)任何(he)接合(he)面或結構(gou)間(jian)隙(xi)，滲透到外(wai)殼(ke)(ke)內(nei)部(bu)(bu)的可(ke)燃性混(hun)合(he)物在(zai)內(nei)部(bu)(bu)爆(bao)(bao)炸而(er)不損壞，并(bing)且不會引起(qi)外(wai)部(bu)(bu)由一(yi)種、多(duo)種氣體(ti)或蒸氣形成的爆(bao)(bao)炸性環境的點燃，把可(ke)能產生火花、電弧和(he)危險(xian)溫度(du)的零(ling)部(bu)(bu)件均放(fang)入隔爆(bao)(bao)外(wai)殼(ke)(ke)內(nei)，隔爆(bao)(bao)外(wai)殼(ke)(ke)使(shi)設(she)備(bei)內(nei)部(bu)(bu)空間(jian)與周圍的環境隔開。隔爆(bao)(bao)外(wai)殼(ke)(ke)存在(zai)間(jian)隙(xi)，因(yin)電氣設(she)備(bei)呼吸作(zuo)用和(he)氣體(ti)滲透作(zuo)用，使(shi)內(nei)部(bu)(bu)可(ke)能存在(zai)爆(bao)(bao)炸性氣體(ti)混(hun)合(he)物。

防爆電(dian)磁閥(fa)(fa)工作(zuo)(zuo)(zuo)制(zhi)式:分長(chang)期(qi)工作(zuo)(zuo)(zuo)制(zhi)，反復短(duan)時(shi)(shi)(shi)工作(zuo)(zuo)(zuo)制(zhi)和短(duan)時(shi)(shi)(shi)工作(zuo)(zuo)(zuo)制(zhi)三種(zhong)。防爆電(dian)磁閥(fa)(fa)均為長(chang)期(qi)工作(zuo)(zuo)(zuo)制(zhi)，即線圈允許長(chang)期(qi)通(tong)電(dian)工作(zuo)(zuo)(zuo)。對于長(chang)時(shi)(shi)(shi)間閥(fa)(fa)門開(kai)通(tong)只有(you)短(duan)時(shi)(shi)(shi)關閉的情況，則宜(yi)選(xuan)用(yong)常開(kai)電(dian)磁閥(fa)(fa)。用(yong)在短(duan)時(shi)(shi)(shi)工作(zuo)(zuo)(zuo)制(zhi)而(er)批(pi)量又很大時(shi)(shi)(shi)，可作(zuo)(zuo)(zuo)特殊訂貨以降低功耗(hao)。

防爆電(dian)磁(ci)閥(fa)其(qi)線圈外(wai)殼不(bu)但(dan)具有承受氣體爆炸壓力的隔爆作(zuo)用(yong)(yong)，而且對(dui)氣體爆炸能(neng)量傳遞(di)具有阻滯作(zuo)用(yong)(yong)，安全性能(neng)更高。是特別設計適用(yong)(yong)于傳輸易燃易爆介(jie)質(zhi)或(huo)專用(yong)(yong)于爆炸性危險場(chang)所的特殊電(dian)磁(ci)閥(fa)系列產(chan)品，不(bu)同的環境和流(liu)體應選擇不(bu)同防爆等級的電(dian)磁(ci)閥(fa)
