如何確定自己使用SMC電磁閥幾位幾通

SMC電磁閥在設計用PLC控制氣缸的時候 ，因為電磁閥基本知識的缺失，讓我在這上面浪費的大半天的時間 ，故把我整理的資料，供大家分享。
一、SMC電磁閥幾位幾通的確定：
SMC電磁閥兩位兩通：兩位就是有兩個方框來表示的，兩通就是說有兩個孔來相通（就是說有三個孔就是三通）。
二、SMC電磁閥重點說下兩位三通和：
SMC電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)在氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)(或液路(lu)(lu))上來說，兩(liang)(liang)位(wei)(wei)三(san)通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)具(ju)有(you)1個(ge)(ge)進(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔(接(jie)(jie)進(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan))、1個(ge)(ge)出(chu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔(提供給目(mu)標設(she)備氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan))、1個(ge)(ge)排(pai)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔(一(yi)(yi)(yi)般安(an)裝(zhuang)一(yi)(yi)(yi)個(ge)(ge)消聲器，如果不怕噪音的(de)(de)話也可(ke)(ke)(ke)以(yi)不裝(zhuang))。 兩(liang)(liang)位(wei)(wei)五通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)具(ju)有(you)1個(ge)(ge)進(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔(接(jie)(jie)進(jin)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan))、1個(ge)(ge)正(zheng)(zheng)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔和(he)1個(ge)(ge)反(fan)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)出(chu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔(分(fen)別(bie)提供給目(mu)標設(she)備的(de)(de)一(yi)(yi)(yi)正(zheng)(zheng)一(yi)(yi)(yi)反(fan)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan))、1個(ge)(ge)正(zheng)(zheng)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)排(pai)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔和(he)1個(ge)(ge)反(fan)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)排(pai)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔(安(an)裝(zhuang)消聲器)。 對于(yu)(yu)小型(xing)(xing)(xing)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)控(kong)(kong)(kong)制設(she)備，氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)管一(yi)(yi)(yi)般選用8~12mm的(de)(de)工業膠氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)管。在電(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)上來說，兩(liang)(liang)位(wei)(wei)三(san)通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)一(yi)(yi)(yi)般為單電(dian)(dian)(dian)(dian)控(kong)(kong)(kong)(即(ji)單線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan))，兩(liang)(liang)位(wei)(wei)五通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)一(yi)(yi)(yi)般為雙(shuang)電(dian)(dian)(dian)(dian)控(kong)(kong)(kong)(即(ji)雙(shuang)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan))。線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)電(dian)(dian)(dian)(dian)壓等級(ji)一(yi)(yi)(yi)般采用DC24V、AC220V等。 兩(liang)(liang)位(wei)(wei)三(san)通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)分(fen)為常閉(bi)(bi)型(xing)(xing)(xing)和(he)常開(kai)(kai)型(xing)(xing)(xing)兩(liang)(liang)種，常閉(bi)(bi)型(xing)(xing)(xing)指(zhi)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)沒通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)時(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)是(shi)(shi)(shi)斷(duan)(duan)的(de)(de)，常開(kai)(kai)型(xing)(xing)(xing)指(zhi)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)沒通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)時(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)是(shi)(shi)(shi)通(tong)(tong)(tong)(tong)(tong)的(de)(de)。常閉(bi)(bi)型(xing)(xing)(xing)兩(liang)(liang)位(wei)(wei)三(san)通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)原理：給線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)接(jie)(jie)通(tong)(tong)(tong)(tong)(tong)，線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)一(yi)(yi)(yi)旦斷(duan)(duan)電(dian)(dian)(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)就會斷(duan)(duan)開(kai)(kai)，這(zhe)相當于(yu)(yu)“點(dian)動(dong)(dong)(dong)(dong)(dong)(dong)”。 常開(kai)(kai)型(xing)(xing)(xing)兩(liang)(liang)位(wei)(wei)三(san)通(tong)(tong)(tong)(tong)(tong)單電(dian)(dian)(dian)(dian)控(kong)(kong)(kong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)原理：給線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)通(tong)(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)斷(duan)(duan)開(kai)(kai)，線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)一(yi)(yi)(yi)旦斷(duan)(duan)電(dian)(dian)(dian)(dian)，氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)路(lu)(lu)就會接(jie)(jie)通(tong)(tong)(tong)(tong)(tong)，這(zhe)也是(shi)(shi)(shi)“點(dian)動(dong)(dong)(dong)(dong)(dong)(dong)”。
