△p>1MPa)的場(chǎng)合。通過(guò)提高氣源壓力增大執(zhí)行機(jī)構(gòu)的輸出力，以克服液體對(duì)閥芯產(chǎn)生的不平衡力，減小行程誤差。當(dāng)被調(diào)介質(zhì)為高溫、高壓、低溫、有毒、易燃、易爆時(shí)，為了防止對(duì)外泄漏，往往將填料壓得很緊，因此閥桿與填料間的摩擦力較大，此時(shí)用定位器可克服時(shí)滯。被調(diào)介質(zhì)為粘性流體或含有固體懸浮物時(shí)，用定位器可以克服介質(zhì)對(duì)閥桿移動(dòng)的阻力。用于大口徑(Dg>100mm)的調(diào)節(jié)閥，以增大執(zhí)行機(jī)構(gòu)的輸出推力。當(dāng)調(diào)節(jié)器與執(zhí)行器距離在60m以上時(shí)，用定位器可克服控制信號(hào)的傳遞滯后，改善閥門的動(dòng)作反應(yīng)速度。用來(lái)改善調(diào)節(jié)閥的流量特性。一個(gè)調(diào)節(jié)器控制兩個(gè)執(zhí)行器實(shí)行分程控制時(shí)，可用兩個(gè)定位器，分別接受低輸入信號(hào)和高輸入信號(hào)，則一個(gè)執(zhí)行器低程動(dòng)作，另一個(gè)高程動(dòng)作，即構(gòu)成了分程調(diào)節(jié)。定位器閥桿與填料間的摩擦力較大，此時(shí)用定位器可克服時(shí)滯。山東直行程電氣閥門定位器價(jià)格</p><p style="text-indent:25px">執(zhí)行機(jī)構(gòu)按信號(hào)來(lái)源的種類分有氣動(dòng)，電動(dòng)，液動(dòng)三大類。山東直行程電氣閥門定位器價(jià)格</p><p style="text-indent:25px">閥門定位器輸入信號(hào)是模擬信號(hào)或數(shù)字信號(hào)，可分為普通閥門定位器和現(xiàn)場(chǎng)總線電氣閥門定位器。普通閥門定位器的輸入信號(hào)是模擬氣壓或電流、電壓信號(hào)，現(xiàn)場(chǎng)總線電氣閥門定位器的輸入信號(hào)是現(xiàn)場(chǎng)總線的數(shù)字信號(hào)。按動(dòng)作的方向可分為單向閥門定位器和雙向閥門定位器。單向閥門定位器用于活塞式執(zhí)行機(jī)構(gòu)時(shí)，閥門定位器只有一個(gè)方向起作用，雙向閥門定位器作用在活塞式執(zhí)行機(jī)構(gòu)氣缸的兩側(cè)，在兩個(gè)方向起作用。按閥門定位器輸出和輸入信號(hào)的增益符號(hào)分為正作用閥門定位器和反作用閥門定位器。正作用閥門定位器的輸入信號(hào)增加時(shí)，輸出信號(hào)也增加，因此，增益為正。反作用閥門定位器的輸入信號(hào)增加時(shí)，輸出信號(hào)減小，因此，增益為負(fù)。山東直行程電氣閥門定位器價(jià)格</p></p><br
