(1)用于對(duì)調(diào)節(jié)質(zhì)量要求高的重要調(diào)節(jié)系統(tǒng),以提高調(diào)節(jié)閥的定位精確及可靠性。
(2)用于閥門兩端壓差大( △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。
(3)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。
(4)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。
(5)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。
