執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)分為氣動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)和電(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)2大類，氣動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)是(shi)以壓縮氣源(yuan)(yuan)為驅動(dong)(dong)(dong)力，配合閥門定位(wei)器(qi)(qi)的(de)控制，實(shi)現(xian)(xian)對閥門全(quan)行(xing)(xing)(xing)(xing)(xing)程(cheng)的(de)調節效(xiao)果，若配以電(dian)磁閥和限(xian)位(wei)開關(guan)則實(shi)現(xian)(xian)對閥門的(de)快速開閉效(xiao)果。 電(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)是(shi)以伺服電(dian)機為驅動(dong)(dong)(dong)源(yuan)(yuan)，受控于4-20mA或ON-OFF信號，實(shi)現(xian)(xian)去閥門全(quan)行(xing)(xing)(xing)(xing)(xing)程(cheng)的(de)控制。常(chang)用的(de)有AT型氣缸,AW型氣缸,CHV電(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi),CHQ防爆電(dian)動(dong)(dong)(dong)執(zhi)行(xing)(xing)(xing)(xing)(xing)器(qi)(qi)等。
附(fu)件(jian)有閥門定(ding)位(wei)器,電磁閥,氣源三聯件(jian),行程限位(wei)開關,保(bao)位(wei)閥等，以實現(xian)對閥門的控制和信(xin)號的反饋。
