style="text-indent:25px">定位器的輸入信號是標(biāo)準(zhǔn)電流或電壓信號，例如，4~20mA電流信號或1~5V電壓信號等，在定位器內(nèi)部將電信號轉(zhuǎn)換為電磁力，然后輸出氣信號到撥動(dòng)控制閥。智能定位器它將控制室輸出的電流信號轉(zhuǎn)換成驅(qū)動(dòng)調(diào)節(jié)閥的氣信號，根據(jù)調(diào)節(jié)閥工作時(shí)閥桿摩擦力，抵消介質(zhì)壓力波動(dòng)而產(chǎn)生的不平衡力，使閥門開度對應(yīng)于控制室輸出的電流信號。并且可以進(jìn)行智能組態(tài)設(shè)置相應(yīng)的參數(shù)，達(dá)到改善控制閥性能的目的。定位器是調(diào)節(jié)閥的主要附件，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(dòng)調(diào)節(jié)閥，當(dāng)調(diào)節(jié)閥動(dòng)作后，閥桿的位移又通過機(jī)械裝置反饋到定位器，閥位狀況可以通過電信號傳給上位系統(tǒng)。上海雙作用電氣閥門定位器廠家排行</p><p
