執(zhi)(zhi)行(xing)器(qi)(qi)(qi)分為(wei)氣動(dong)執(zhi)(zhi)行(xing)器(qi)(qi)(qi)和電(dian)(dian)動(dong)執(zhi)(zhi)行(xing)器(qi)(qi)(qi)2大類，氣動(dong)執(zhi)(zhi)行(xing)器(qi)(qi)(qi)是以(yi)壓縮氣源為(wei)驅動(dong)力，配(pei)合閥(fa)門(men)定位器(qi)(qi)(qi)的控(kong)制(zhi)，實(shi)現對閥(fa)門(men)全(quan)(quan)行(xing)程的調(diao)節效果，若配(pei)以(yi)電(dian)(dian)磁閥(fa)和限(xian)位開關則(ze)實(shi)現對閥(fa)門(men)的快速開閉效果。 電(dian)(dian)動(dong)執(zhi)(zhi)行(xing)器(qi)(qi)(qi)是以(yi)伺服電(dian)(dian)機為(wei)驅動(dong)源，受控(kong)于4-20mA或ON-OFF信號，實(shi)現去閥(fa)門(men)全(quan)(quan)行(xing)程的控(kong)制(zhi)。常用的有AT型氣缸,AW型氣缸,CHV電(dian)(dian)動(dong)執(zhi)(zhi)行(xing)器(qi)(qi)(qi),CHQ防爆電(dian)(dian)動(dong)執(zhi)(zhi)行(xing)器(qi)(qi)(qi)等(deng)。
附件(jian)有閥門(men)定位(wei)器,電(dian)磁閥,氣(qi)源三聯件(jian),行(xing)程限位(wei)開關(guan),保(bao)位(wei)閥等，以實現對閥門(men)的控制和信號的反(fan)饋。
