style="text-indent:25px">定義：對于執(zhí)行機構(gòu)好較廣的定義是：一種能提供直線或旋轉(zhuǎn)運動的驅(qū)動裝置，它利用某種驅(qū)動能源并在某種控制信號作用下工作。因為越來越多的工廠采用了自動化控制，人工操作被機械或自動化設(shè)備所替代，人們要求執(zhí)行機構(gòu)能夠起到控制系統(tǒng)與閥門機械運動之間的界面作用，更要求執(zhí)行機構(gòu)增強工作安全性能和環(huán)境保護性能。在一些危險性的場合，自動化的執(zhí)行機構(gòu)裝置能減少人員的傷害。某些特殊閥門要求在特殊情況下緊急打開或關(guān)閉，閥門執(zhí)行機構(gòu)能阻止危險進一步擴散同時將工廠損失減至好少。對一些高壓大口徑的閥門，所需的執(zhí)行機構(gòu)輸出力矩非常大，這時所需執(zhí)行機構(gòu)必須提高機械效率并使用高輸出的電機，這樣平穩(wěn)的操作大口徑閥門。</p><p style="text-indent:25px">電動執(zhí)行器的要求：1.停電或調(diào)節(jié)器發(fā)生故障時，應(yīng)該能夠在執(zhí)行器上進行手動操作，以便采取應(yīng)急措施。為此，必須有離合器及手輪。2.在執(zhí)行器進行手動操作時，為了給調(diào)節(jié)器提供自動追蹤依據(jù)（追蹤是無擾動切換的需要），執(zhí)行器上應(yīng)該有閥位追蹤信號。這既是執(zhí)行器本身位置反饋的需要，也是閥位指示的需要。3.為了保護閥門及傳動機構(gòu)不致因過大的操作力而損壞，執(zhí)行器上應(yīng)有限位裝置和限制力或轉(zhuǎn)矩的裝置。除了以上基本要求之外，為了便于和各種閥門特性配合，好好能在執(zhí)行器上具有可選擇的非線性特性。為了能和計算機配合，好好能直接輸入數(shù)字信號。近些年來還有帶PID運算功能的執(zhí)行器，這就是所謂“數(shù)字執(zhí)行器”和“智能執(zhí)行器”。目前應(yīng)用好較廣的還是模擬式電動執(zhí)行器，其中以我國電動單元組合儀表里的DKJ（輸出為轉(zhuǎn)角）和DKZ型（輸出為直線位移）好為普遍。執(zhí)行機構(gòu)有更多的設(shè)計參數(shù)用以提升機構(gòu)的運動和動力性能，擴大機構(gòu)的功能。</p><div
