style="text-indent:25px">氣動閥門借助于控制活塞的作用，每個空氣通路同時會有不同程度的打開或關(guān)閉。這不僅啟動氣缸移動方向的開環(huán)或閉環(huán)控制，還對氣缸的移動速度進行控制。因此，可以認為這種閥起到節(jié)流的功能，在切換頻率約為100Hz時，這種類型的閥可以達到相當(dāng)高的動態(tài)性能。比例閥有范圍廣闊的應(yīng)用領(lǐng)域，例如，在材料開卷時，應(yīng)用比例閥能以氣動方式保持開卷過程中的恒定張力。比例方向控制閥在氣缸定位方面有進一步的應(yīng)用，在這種情況，氣缸配置一個位移編碼器，該編碼器提供活塞實際位置的反饋信號。</p><p style="text-indent:25px">閥門定位器，按結(jié)構(gòu)分氣動閥門定位器、電氣閥門定位器及智能閥門定位器，是調(diào)節(jié)閥的主要附件，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(dāng)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)。閥門定位器能夠增大調(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)閥的正確定位。主要工作原理：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(dāng)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，建立了閥桿位移量與控制器輸出信號之間的一一對應(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。氣動閥門關(guān)閉狀況下的任何一側(cè)應(yīng)能承受1.1倍閥門工壓值而不滲漏。</p><div
