氣動閥門定位器是按力矩平衡原理工作的，當(dāng)通入波紋管2的信號壓力P1增加時，使主杠桿3繞支點(diǎn)轉(zhuǎn)動，使噴嘴擋板9靠近噴嘴，噴嘴背壓經(jīng)單向放大器8放大后，通入到執(zhí)行機(jī)構(gòu)薄膜室的壓力增加，使閥桿向下移動。并帶動反饋桿繞支點(diǎn)轉(zhuǎn)動，反饋凸輪也隨之作逆時針方向轉(zhuǎn)動，通過滾輪使副杠桿4繞支點(diǎn)轉(zhuǎn)動，并將反饋彈簧拉伸，彈簧對主杠桿3的拉力與信號壓力用在波紋管上的力達(dá)到力矩平衡時，儀表達(dá)到平衡狀態(tài)。執(zhí)行機(jī)構(gòu)的閥位維持在一*的開度上，一*的信號壓力就對應(yīng)于一*的閥位開度。以上作用方式為正作用，若要改變作用方式，只要將凸輪翻轉(zhuǎn)，A向變成B向等，即可。所謂正作用定位器，就是信號壓力增加，輸出壓力亦增加；所謂反作用定位器，就是信號壓力增加，輸出壓力則減少。一臺正作用執(zhí)行機(jī)構(gòu)只要裝上反作用定位器，就能實(shí)現(xiàn)反作用執(zhí)行機(jī)構(gòu)的動作；相反，一臺反作用執(zhí)行機(jī)構(gòu)只要裝上反作用定位器，就能實(shí)現(xiàn)正作用執(zhí)行機(jī)構(gòu)的動作。
