很多人對于SMC電磁閥的結構原理是不清楚，但是很想要知道這些很不錯的機械原理，同時想要深入研究！

一(yi):直動式電(dian)(dian)(dian)(dian)磁(ci)(ci)閥有(you)常(chang)(chang)(chang)(chang)閉型和常(chang)(chang)(chang)(chang)開型二種.常(chang)(chang)(chang)(chang)閉型斷(duan)電(dian)(dian)(dian)(dian)時(shi)呈關閉狀(zhuang)態,當(dang)線(xian)圈通(tong)電(dian)(dian)(dian)(dian)時(shi) 產生(sheng)電(dian)(dian)(dian)(dian)磁(ci)(ci)力(li),使動鐵芯(xin)克服彈簧(huang)力(li)同靜鐵芯(xin)吸合直接開啟閥,介(jie)質(zhi) 呈通(tong)路; 當(dang)線(xian)圈斷(duan)電(dian)(dian)(dian)(dian)時(shi)電(dian)(dian)(dian)(dian)磁(ci)(ci)力(li)消失, 動鐵芯(xin)在彈簧(huang)力(li)的(de)作(zuo)用下復位, 直接關閉SMC電(dian)(dian)(dian)(dian)磁(ci)(ci)閥有(you)什么(me)作(zuo)用之(zhi)處，閥口,介(jie)質(zhi)不通(tong).結構簡(jian)單,動作(zuo)可靠,在零壓差和微真 空下正常(chang)(chang)(chang)(chang)工作(zuo). 常(chang)(chang)(chang)(chang)開型正好(hao)相反. 如小于 φ6 流量通(tong)徑的(de)電(dian)(dian)(dian)(dian)磁(ci)(ci)閥. （圖 一(yi)是典型結構圖）

二(er),分步直(zhi)動式電(dian)磁(ci)閥(fa)(fa)(fa)(fa)該閥(fa)(fa)(fa)(fa)采用(yong)一(yi)次開(kai)閥(fa)(fa)(fa)(fa)和(he)(he)二(er)次開(kai)閥(fa)(fa)(fa)(fa)連在(zai)(zai)一(yi)體,主(zhu)(zhu)閥(fa)(fa)(fa)(fa)和(he)(he)導(dao)閥(fa)(fa)(fa)(fa)分步使(shi)電(dian)磁(ci)力(li)(li)(li)(li) 和(he)(he)壓差直(zhi)接開(kai)啟(qi)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)口(kou). 當線圈(quan)通(tong)(tong)電(dian)時(shi)(shi)(shi), 產生(sheng)電(dian)磁(ci)力(li)(li)(li)(li)使(shi)動鐵芯(xin) 和(he)(he) 靜鐵芯(xin)吸合,導(dao)閥(fa)(fa)(fa)(fa)口(kou)開(kai)啟(qi)而(er)導(dao)閥(fa)(fa)(fa)(fa)口(kou)設在(zai)(zai)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)口(kou)上(shang),且動鐵芯(xin)與主(zhu)(zhu)閥(fa)(fa)(fa)(fa) 芯(xin)連在(zai)(zai)一(yi)起(qi),此(ci)時(shi)(shi)(shi)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)上(shang)腔的壓力(li)(li)(li)(li)通(tong)(tong)過導(dao)閥(fa)(fa)(fa)(fa)口(kou)卸荷(he),在(zai)(zai)壓力(li)(li)(li)(li)差和(he)(he)電(dian) 磁(ci)力(li)(li)(li)(li)的同時(shi)(shi)(shi)作(zuo)(zuo)(zuo)用(yong)下(xia)(xia)使(shi)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)芯(xin)向(xiang)上(shang)運(yun)動,開(kai)啟(qi)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)介(jie)質流通(tong)(tong).當線圈(quan) 斷(duan)電(dian)時(shi)(shi)(shi)電(dian)磁(ci)力(li)(li)(li)(li)消失(shi),此(ci)時(shi)(shi)(shi)動鐵芯(xin)在(zai)(zai)自(zi)重和(he)(he)彈簧(huang)力(li)(li)(li)(li)的作(zuo)(zuo)(zuo)用(yong)下(xia)(xia)關(guan)閉導(dao)閥(fa)(fa)(fa)(fa) 孔(kong),此(ci)時(shi)(shi)(shi)介(jie)質在(zai)(zai)平衡孔(kong)中(zhong)進入主(zhu)(zhu)閥(fa)(fa)(fa)(fa)芯(xin)上(shang)腔,使(shi)上(shang)腔壓力(li)(li)(li)(li)升高,此(ci)時(shi)(shi)(shi) 在(zai)(zai)彈簧(huang)復(fu)位和(he)(he)壓力(li)(li)(li)(li)的作(zuo)(zuo)(zuo)用(yong)下(xia)(xia)關(guan)閉主(zhu)(zhu)閥(fa)(fa)(fa)(fa),介(jie)質斷(duan)流.結構合理,動作(zuo)(zuo)(zuo) 可靠(kao),在(zai)(zai)零(ling)壓差時(shi)(shi)(shi)工作(zuo)(zuo)(zuo)也可靠(kao).如:ZQDF,ZS,2W 等.

三(san),間(jian)接先(xian)導式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa) 該系(xi)列(lie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)由先(xian)導閥(fa)(fa)(fa)(fa)(fa)和(he)主(zhu)閥(fa)(fa)(fa)(fa)(fa)芯聯系(xi)著形(xing)成通(tong)道組合而成;常閉(bi)型(xing)(xing) 在(zai)未通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi),呈關(guan)(guan)(guan)(guan)閉(bi)狀態.當(dang)線圈(quan)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi),產生的(de)(de)(de)(de)磁(ci)(ci)(ci)(ci)(ci)力使動鐵芯和(he) 靜鐵芯吸合,導閥(fa)(fa)(fa)(fa)(fa)口(kou)(kou)(kou)打開(kai),介(jie)質(zhi)(zhi)流(liu)向(xiang)(xiang)出口(kou)(kou)(kou),此時(shi)(shi)(shi)主(zhu)閥(fa)(fa)(fa)(fa)(fa)芯上(shang)腔壓(ya)(ya)力減 少,低于(yu)(yu)進口(kou)(kou)(kou)側的(de)(de)(de)(de)壓(ya)(ya)力,形(xing)成壓(ya)(ya)差(cha)克(ke)服彈簧(huang)阻力而隨之向(xiang)(xiang)上(shang)運動, 達(da)到開(kai)啟(qi)主(zhu)閥(fa)(fa)(fa)(fa)(fa)口(kou)(kou)(kou)的(de)(de)(de)(de)目的(de)(de)(de)(de),介(jie)質(zhi)(zhi)流(liu)通(tong).當(dang)線圈(quan)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi),磁(ci)(ci)(ci)(ci)(ci)力消失,動 鐵芯在(zai)彈簧(huang)力作(zuo)用(yong)(yong)(yong)(yong)下復位關(guan)(guan)(guan)(guan)閉(bi)先(xian)導口(kou)(kou)(kou),此時(shi)(shi)(shi)介(jie)質(zhi)(zhi)從平(ping)衡孔流(liu)入,主(zhu) 閥(fa)(fa)(fa)(fa)(fa)芯上(shang)腔壓(ya)(ya)力增大(da),并在(zai)彈簧(huang)力的(de)(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)下向(xiang)(xiang)下運動,關(guan)(guan)(guan)(guan)閉(bi)主(zhu)閥(fa)(fa)(fa)(fa)(fa)口(kou)(kou)(kou). 常開(kai)式(shi)(shi)原理正(zheng)好相反.如(ru):SLA,DF（φ15 以(yi)(yi)上(shang)口(kou)(kou)(kou)徑(jing)(jing)）,ZCZ 等. （圖(tu)三(san)是典(dian)型(xing)(xing)結構圖(tu)）
