電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)是(shi)由電(dian)(dian)(dian)磁(ci)(ci)(ci)線圈和磁(ci)(ci)(ci)芯(xin)組成，是(shi)包含一個(ge)或(huo)幾個(ge)孔的閥(fa)(fa)(fa)(fa)(fa)體(ti)。當線圈通(tong)電(dian)(dian)(dian)或(huo)斷電(dian)(dian)(dian)時(shi)，磁(ci)(ci)(ci)芯(xin)的運(yun)轉(zhuan)將(jiang)導(dao)致流(liu)體(ti)通(tong)過閥(fa)(fa)(fa)(fa)(fa)體(ti)或(huo)被切(qie)斷，以達(da)到改變流(liu)體(ti)方向的目的。按功能分類(lei)：水用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、制(zhi)冷電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、低(di)溫電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、消(xiao)防電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氨用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氣體(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液(ye)體(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa) 常開(kai)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、油用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、直流(liu)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)。
    直動式(shi)電(dian)磁(ci)閥：有常閉(bi)(bi)型(xing)和常開(kai)型(xing)二(er)種。常閉(bi)(bi)型(xing)斷電(dian)時呈(cheng)關閉(bi)(bi)狀態，當線(xian)圈通電(dian)時產生電(dian)磁(ci)力，使動鐵(tie)芯克服彈簧(huang)力同靜鐵(tie)芯吸合著界開(kai)啟閥，介質呈(cheng)通路；當線(xian)圈斷電(dian)時電(dian)磁(ci)力消失，動鐵(tie)芯在(zai)彈簧(huang)力的作(zuo)(zuo)用下復(fu)位，直接關閉(bi)(bi)窗口，介質不通，結構(gou)簡(jian)單，動作(zuo)(zuo)可靠，在(zai)零壓差和微真空下正常工作(zuo)(zuo)。常開(kai)型(xing)正好相反。如小于(yu)Φ6流(liu)量通經的電(dian)磁(ci)閥。
    分步直(zhi)動式(shi)電磁(ci)閥(fa)(fa)(fa)(fa)：該閥(fa)(fa)(fa)(fa)采(cai)用(yong)一(yi)次開(kai)(kai)閥(fa)(fa)(fa)(fa)和(he)二次開(kai)(kai)閥(fa)(fa)(fa)(fa)連(lian)在(zai)(zai)一(yi)體，主(zhu)閥(fa)(fa)(fa)(fa)和(he)導閥(fa)(fa)(fa)(fa)分步使(shi)電磁(ci)力和(he)壓(ya)(ya)差直(zhi)接開(kai)(kai)啟(qi)主(zhu)閥(fa)(fa)(fa)(fa)口(kou)(kou)。當線圈通電時(shi)(shi)(shi)(shi)，產(chan)生電磁(ci)力使(shi)動鐵芯(xin)和(he)靜鐵芯(xin)吸(xi)合(he)，導閥(fa)(fa)(fa)(fa)口(kou)(kou)開(kai)(kai)啟(qi)而(er)導閥(fa)(fa)(fa)(fa)口(kou)(kou)設在(zai)(zai)主(zhu)閥(fa)(fa)(fa)(fa)口(kou)(kou)上(shang)，且動鐵芯(xin)與(yu)主(zhu)閥(fa)(fa)(fa)(fa)芯(xin)連(lian)在(zai)(zai)一(yi)起，此時(shi)(shi)(shi)(shi)主(zhu)閥(fa)(fa)(fa)(fa)上(shang)腔的壓(ya)(ya)力通過(guo)導砝口(kou)(kou)卸荷，在(zai)(zai)壓(ya)(ya)力差和(he)電磁(ci)力的同(tong)時(shi)(shi)(shi)(shi)作用(yong)下使(shi)主(zhu)閥(fa)(fa)(fa)(fa)芯(xin)向上(shang)運動，開(kai)(kai)啟(qi)閥(fa)(fa)(fa)(fa)介(jie)質流(liu)通。當線圈斷電時(shi)(shi)(shi)(shi)電磁(ci)力消失(shi)，此時(shi)(shi)(shi)(shi)動鐵芯(xin)在(zai)(zai)自(zi)重和(he)彈簧(huang)力的作用(yong)下關(guan)閉導閥(fa)(fa)(fa)(fa)孔(kong)，此時(shi)(shi)(shi)(shi)介(jie)質在(zai)(zai)平衡孔(kong)中進入主(zhu)閥(fa)(fa)(fa)(fa)芯(xin)上(shang)腔，使(shi)上(shang)腔壓(ya)(ya)力升高，此時(shi)(shi)(shi)(shi)在(zai)(zai)彈簧(huang)復位(wei)和(he)壓(ya)(ya)力的作用(yong)下關(guan)閉主(zhu)閥(fa)(fa)(fa)(fa)，介(jie)質斷流(liu)。結構合(he)理，動作可靠，在(zai)(zai)零壓(ya)(ya)差時(shi)(shi)(shi)(shi)工作也(ye)可靠。

    間接先(xian)導式電(dian)磁(ci)(ci)閥(fa)(fa)(fa)：該系(xi)列電(dian)磁(ci)(ci)閥(fa)(fa)(fa)和(he)主(zhu)閥(fa)(fa)(fa)芯聯(lian)系(xi)著形成通(tong)道(dao)組合而成；常閉型在(zai)未通(tong)電(dian)時(shi)(shi)，呈關閉狀態。當線圈通(tong)電(dian)時(shi)(shi)，產生的(de)磁(ci)(ci)力(li)使動鐵(tie)芯和(he)靜鐵(tie)芯吸合，導閥(fa)(fa)(fa)口(kou)打開，介(jie)質流向出口(kou)，此時(shi)(shi)主(zhu)閥(fa)(fa)(fa)芯上腔壓力(li)減少，低(di)于進(jin)口(kou)側的(de)壓力(li)，形成壓差(cha)克服彈簧阻(zu)力(li)而隨(sui)之(zhi)向上運動，達到開啟主(zhu)閥(fa)(fa)(fa)口(kou)的(de)目的(de)，介(jie)質流通(tong)。當線圈斷電(dian)時(shi)(shi)，磁(ci)(ci)力(li)消失，動鐵(tie)芯在(zai)彈簧力(li)作用(yong)下復(fu)位(wei)關閉先(xian)導口(kou)，此時(shi)(shi)介(jie)質從(cong)平(ping)衡孔流入(ru)，主(zhu)閥(fa)(fa)(fa)鋅上腔壓力(li)增大，并在(zai)彈簧力(li)的(de)作用(yong)下向下運動，關閉閥(fa)(fa)(fa)口(kou)。常開式原理正(zheng)好相(xiang)反。
電磁閥的選型常識：
    ①爆炸性(xing)環境必須(xu)選用相(xiang)應(ying)的防爆電(dian)磁閥；
    ②電磁閥一般(ban)不防水(shui)，在(zai)條件(jian)不允許時(shi)請(qing)請(qing)選(xuan)用防水(shui)型(xing)；
    ③動(dong)(dong)作時間很短頻率較高時一般選取直動(dong)(dong)式，大口徑選用快速系(xi)列；
    ④有腐(fu)蝕性液(ye)體的應選(xuan)(xuan)用全不銹鋼型，強腐(fu)蝕性流體宜(yi)選(xuan)(xuan)用塑料王(SLF)電磁(ci)閥；
    ⑤電(dian)磁閥分為常閉(bi)(bi)和常開(kai)二種，一般(ban)選(xuan)用(yong)常閉(bi)(bi)型，通電(dian)打開(kai)，斷電(dian)關(guan)閉(bi)(bi)；但在(zai)開(kai)啟(qi)時間(jian)(jian)很長關(guan)閉(bi)(bi)時間(jian)(jian)很短時要選(xuan)用(yong)常開(kai)型；
    ⑥工作壓(ya)(ya)差，管路較高壓(ya)(ya)差在小于0.04MPa時應選(xuan)用(yong)(yong)如2W、ZQDF、DFA系列等直動(dong)式和分步直動(dong)式，較低工作壓(ya)(ya)差大于0.04MPa時可(ke)選(xuan)用(yong)(yong)先導式(壓(ya)(ya)差式)電磁(ci)閥。
