style="text-indent:25px">閥門信號反饋器一般可分為接觸式與非接觸式。接觸式反饋器大多由機械限位開關(guān)構(gòu)成，由于存在機械接觸部分，容易產(chǎn)生火花，所以在防爆場合使用時需加裝隔爆殼體，十分笨重，如果閥門頻繁動作，反饋器的精度和壽命都會有所下降。一般采用NAMUR接近開關(guān)，雖然克服了接觸式反饋器的特點，但在防爆場合需配接柵使用，成本是還可以的。為了解決傳統(tǒng)閥門位置反饋器的不足，提出一種基于閥門信號反饋器。閥門信號反饋器敏度較高，體積小，安裝使用方便，而且成本也比較低。廣州電動閥門信號反饋器機器閥門信號反饋器的增益就基本上不受開環(huán)增益的影響。</p><div

style="text-indent:25px">閥門信號反饋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，建立了閥桿位移倍與控制器輸出信號之間的一一對應關(guān)系。閥門信號反饋器能夠增大調(diào)節(jié)閥的輸出功率，減少調(diào)節(jié)信號的傳遞滯后的情況發(fā)生，加快閥桿的移動速度，能夠提高閥門的線性度，克服閥桿的摩擦力并消除不平衡力的影響，從而保證調(diào)節(jié)閥的正確反饋。閥門信號反饋器用于活塞式執(zhí)行機構(gòu)時，閥門信號反饋器只有一個方向起作用，雙向閥門信號反饋器作用在活塞式執(zhí)行機構(gòu)氣缸的兩側(cè)，在兩個方向起作用。</p><p style="text-indent:25px">閥門信號反饋器大多數(shù)時候閥位反饋器指開關(guān)量的位置反饋，實際上可能就是一個或兩個行程開關(guān)；而位置變送器則指連續(xù)量的位置反饋裝置。閥門信號反饋器按閥門反饋器輸出和輸入信號的增益符號分為正作用閥門反饋器和反作用閥門反饋器。正作用閥門反饋器的輸入信號增加時，輸出信號也增加，因此，增益為正。反作用閥門反饋器的輸入信號增加時，輸出信號減小，因此，增益為負。閥門信號反饋器按閥門反饋器是否帶CPU可分為普通電氣閥門反饋器和智能電氣閥門反饋器。普通電氣閥門反饋器沒有CPU，因此，不具有智能，不能處理有關(guān)的智能運算。智能電氣閥門反饋器帶CPU，可處理有關(guān)智能運算，例如，可進行前向通道的非線性補償?shù)?，現(xiàn)場總線電氣閥門反饋器還可帶PID等功能模塊，實現(xiàn)相應的運算。閥門信號反饋器可以進行智能組態(tài)設置相應的參數(shù)，達到改善控制閥性能的目的。</p><div
