△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(mén)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)。自動(dòng)控制、遙控必不可少的驅(qū)動(dòng)設(shè)備，運(yùn)動(dòng)過(guò)程可由筆劃決定。浙江防爆型閥門(mén)定位器生產(chǎn)廠</p><p
