氣(qi)(qi)(qi)(qi)動(dong)(dong)執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)器(qi)是用(yong)氣(qi)(qi)(qi)(qi)壓力(li)驅動(dong)(dong)啟閉或調節閥門的(de)執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)裝(zhuang)置(zhi)，又被(bei)稱(cheng)氣(qi)(qi)(qi)(qi)動(dong)(dong)執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構或氣(qi)(qi)(qi)(qi)動(dong)(dong)裝(zhuang)置(zhi)，不(bu)過一(yi)般通(tong)俗的(de)稱(cheng)之(zhi)為氣(qi)(qi)(qi)(qi)動(dong)(dong)頭(tou)。氣(qi)(qi)(qi)(qi)動(dong)(dong)執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)器(qi)有時還配備(bei)一(yi)定(ding)的(de)輔助裝(zhuang)置(zhi)。常(chang)用(yong)的(de)有閥門定(ding)位器(qi)和手(shou)輪機(ji)構。閥門定(ding)位器(qi)的(de)作用(yong)是利用(yong)反饋原理來改善執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)器(qi)的(de)性能,使執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)器(qi)能按控制(zhi)器(qi)的(de)控制(zhi)信號(hao),實現準確的(de)定(ding)位。手(shou)輪機(ji)構的(de)作用(yong)是當控制(zhi)系統因停電、停氣(qi)(qi)(qi)(qi)、控制(zhi)器(qi)無輸出或執(zhi)(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構失靈時,利用(yong)它可以(yi)直接操縱控制(zhi)閥，以(yi)維(wei)持生產的(de)正(zheng)常(chang)進行(xing)(xing)。
