1．兩(liang)位三通單電(dian)控電(dian)磁閥動(dong)作(zuo)原理
兩位三通(tong)電磁閥分為常閉(bi)型和常開(kai)型兩種，常閉(bi)型指線圈(quan)沒通(tong)電時氣(qi)路是斷的，常開(kai)型指線圈(quan)沒通(tong)電時氣(qi)路是通(tong)的。
常閉型兩(liang)位三通電(dian)磁(ci)閥動作原理：給線圈通電(dian)，氣路接通，線圈一(yi)旦斷(duan)(duan)電(dian)，氣路就(jiu)會(hui)斷(duan)(duan)開，這相當于“點動"。
常(chang)開(kai)型兩(liang)位三通(tong)單電(dian)控電(dian)磁閥動作原理：給線(xian)(xian)圈(quan)通(tong)電(dian)，氣路斷開(kai)，線(xian)(xian)圈(quan)一旦(dan)斷電(dian)，氣路就會(hui)接(jie)通(tong)，這也是(shi)“點動"。
在電(dian)氣上來(lai)說，兩(liang)位(wei)三通(tong)電(dian)磁(ci)閥一般為單電(dian)控(即(ji)單線圈)，
2．兩(liang)位五(wu)通雙電(dian)(dian)控電(dian)(dian)磁閥(fa)動作原理
兩(liang)(liang)位(wei)(wei)五通(tong)(tong)(tong)(tong)電(dian)磁(ci)閥一般(ban)為(wei)雙電(dian)控(kong)(即雙線(xian)圈(quan))。線(xian)圈(quan)電(dian)壓等級(ji)一般(ban)采用DC24V、AC220V等。給(gei)(gei)正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)線(xian)圈(quan)通(tong)(tong)(tong)(tong)電(dian)，則(ze)正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)氣(qi)路接通(tong)(tong)(tong)(tong)(正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)出氣(qi)孔有(you)氣(qi))，即使給(gei)(gei)正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)線(xian)圈(quan)斷(duan)電(dian)后正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)氣(qi)路仍然是(shi)接通(tong)(tong)(tong)(tong)的(de)(de)(de)，將會一直維(wei)持到給(gei)(gei)反(fan)動(dong)(dong)作(zuo)(zuo)線(xian)圈(quan)通(tong)(tong)(tong)(tong)電(dian)為(wei)止(zhi)。 給(gei)(gei)反(fan)動(dong)(dong)作(zuo)(zuo)線(xian)圈(quan)通(tong)(tong)(tong)(tong)電(dian)，則(ze)反(fan)動(dong)(dong)作(zuo)(zuo)氣(qi)路接通(tong)(tong)(tong)(tong)(反(fan)動(dong)(dong)作(zuo)(zuo)出氣(qi)孔有(you)氣(qi))，即使給(gei)(gei)反(fan)動(dong)(dong)作(zuo)(zuo)線(xian)圈(quan)斷(duan)電(dian)后反(fan)動(dong)(dong)作(zuo)(zuo)氣(qi)路仍然是(shi)接通(tong)(tong)(tong)(tong)的(de)(de)(de)，將會一直維(wei)持到給(gei)(gei)正(zheng)(zheng)(zheng)(zheng)動(dong)(dong)作(zuo)(zuo)線(xian)圈(quan)通(tong)(tong)(tong)(tong)電(dian)為(wei)止(zhi)。這(zhe)相當于“自鎖"。基(ji)于兩(liang)(liang)位(wei)(wei)五通(tong)(tong)(tong)(tong)雙電(dian)控(kong)電(dian)磁(ci)閥的(de)(de)(de)這(zhe)種特性(xing)，在(zai)設計(ji)機電(dian)控(kong)制(zhi)回路或編制(zhi)PLC程序的(de)(de)(de)時候，可以只須給(gei)(gei)電(dian)磁(ci)閥線(xian)圈(quan)通(tong)(tong)(tong)(tong)電(dian)1~2秒(miao)就可以了，這(zhe)樣可以保護電(dian)磁(ci)閥線(xian)圈(quan)不(bu)容易損壞(huai)
