style="text-indent:25px">電氣閥門定位器是控制閥的主要附件。它將閥桿位移信號作為輸入的反饋測量信號，以控制器輸出信號作為設(shè)定信號，進行比較，當兩者有偏差時，改變其到執(zhí)行機構(gòu)的輸出信號，使執(zhí)行機構(gòu)動作，從而建立閥桿位移與控制器輸出信號之間的對應(yīng)關(guān)系。因此，閥門定位器組成以閥桿位移為測量信號，以控制器輸出為設(shè)定信號的反饋控制系統(tǒng)。該控制系統(tǒng)的操縱變量是閥門定位器去執(zhí)行機構(gòu)的輸出信號。電氣閥門定位器是氣動調(diào)節(jié)閥重要附件之一，通常與氣動調(diào)節(jié)閥配套使用，它接受調(diào)節(jié)器的輸出信號，然后以它的輸出信號去控制氣動調(diào)節(jié)閥，當調(diào)節(jié)閥動作后，閥桿的位移又通過機械裝置反饋到閥門定位器，閥位狀況通過電信號傳給上位系統(tǒng)。定位器的功能是非常強大的，適用于多種場合。鹽城雙作用閥門定位器供應(yīng)商</p><p
