兩(liang)(liang)位(wei)五通(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)具有1個(ge)(ge)(ge)(ge)進氣(qi)孔(kong)(kong)(接進氣(qi)氣(qi)源)、1個(ge)(ge)(ge)(ge)正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)(zuo)(zuo)出氣(qi)孔(kong)(kong)和(he)1個(ge)(ge)(ge)(ge)反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)(zuo)(zuo)出氣(qi)孔(kong)(kong)(分別提供給(gei)(gei)(gei)(gei)目標設備的正(zheng)(zheng)(zheng)(zheng)反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)(zuo)(zuo)的氣(qi)源)、1個(ge)(ge)(ge)(ge)正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)(zuo)(zuo)排(pai)(pai)氣(qi)孔(kong)(kong)和(he)1個(ge)(ge)(ge)(ge)反(fan)(fan)動(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)(zuo)(zuo)(zuo)(zuo)排(pai)(pai)氣(qi)孔(kong)(kong)(安(an)裝消(xiao)聲器)。 對于(yu)小型(xing)(xing)自動(dong)(dong)(dong)(dong)(dong)控(kong)制設備，氣(qi)管般選用8~12mm的工業膠(jiao)氣(qi)管。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)般選用日(ri)(ri)本(ben)SMC(點(dian)，不(bu)(bu)(bu)過是小日(ri)(ri)本(ben)的產(chan)品)、中(zhong)國(guo)臺灣亞德(de)客(ke)(實惠，也不(bu)(bu)(bu)錯)或(huo)其它國(guo)產(chan)品牌(pai)等(deng)(deng)等(deng)(deng)。 在電(dian)(dian)(dian)(dian)氣(qi)上來說，兩(liang)(liang)位(wei)三(san)(san)通(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)般為(wei)(wei)單電(dian)(dian)(dian)(dian)控(kong)(即(ji)單線(xian)(xian)(xian)圈(quan)(quan)(quan))，兩(liang)(liang)位(wei)五通(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)般為(wei)(wei)雙電(dian)(dian)(dian)(dian)控(kong)(即(ji)雙線(xian)(xian)(xian)圈(quan)(quan)(quan))。線(xian)(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)(dian)(dian)壓等(deng)(deng)般采用DC24V、AC220V等(deng)(deng)。 兩(liang)(liang)位(wei)三(san)(san)通(tong)(tong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)(fa)(fa)分為(wei)(wei)常閉(bi)(bi)型(xing)(xing)和(he)常開(kai)型(xing)(xing)兩(liang)(liang)種，常閉(bi)(bi)型(xing)(xing)指線(xian)(xian)(xian)圈(quan)(quan)(quan)沒(mei)通(tong)(tong)電(dian)(dian)(dian)(dian)時(shi)(shi)氣(qi)路(lu)(lu)(lu)是斷的，常開(kai)型(xing)(xing)指線(xian)(xian)(xian)圈(quan)(quan)(quan)沒(mei)通(tong)(tong)電(dian)(dian)(dian)(dian)時(shi)(shi)氣(qi)路(lu)(lu)(lu)是通(tong)(tong)的。
