style="text-indent:25px">閥門定位器是依靠壓縮空氣來驅(qū)動的閥門，主要由氣動執(zhí)行機(jī)構(gòu)配用各種型號的閥門組成。閥門定位器的型號很多，氣動調(diào)節(jié)閥、氣動球閥、氣動蝶閥等動力源為氣源驅(qū)動的閥門都可以被稱為閥門定位器。配用不同的附件，閥門定位器有調(diào)節(jié)型和開關(guān)型兩種形式。氣動開關(guān)型閥門是依靠電磁閥切換氣源，來實現(xiàn)閥門的啟閉。主要用在工況中做截斷或接通管道介質(zhì)用，氣動調(diào)節(jié)閥型閥門需要配用定位器，接收控制系統(tǒng)發(fā)送的4-20mA或1-5V等模擬信號，控制閥門的開度大小，用于要求調(diào)節(jié)管道介質(zhì)參數(shù)的工況。并且可會根據(jù)用戶工況的需要選擇氣開型或氣關(guān)型。</p><p style="text-indent:25px">閥門定位器按動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，閥門定位器只有一個方向起作用，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)，從兩個方向起作用。按閥門定位器輸出和輸入信號的增益符號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增加時，輸出信號也增加，因此，增益為正。反作用閥門定位器的輸入信號增加時，輸出信號減小，因此，增益為負(fù)。按閥門定位器輸入信號是模擬信號或數(shù)字信號，可分為普通閥門定位器和現(xiàn)場總線電氣閥門定位器。普通閥門定位器的輸入信號是模擬氣壓或電流、電壓信號，現(xiàn)場總線電氣閥門定位器的輸入信號是現(xiàn)場總線的數(shù)字信號。調(diào)節(jié)器輸出信號送至閥門定位器。</p><div

style="text-indent:25px">定位器要避免閥自身不穩(wěn)定區(qū)工作法：有的定位器避免閥自身不穩(wěn)定區(qū)工作法，比如說雙座閥，開度在10％以內(nèi)，因上球處流開，下球處流閉，帶來不穩(wěn)定的問題；又或者是不平衡力變化斜率產(chǎn)生交變的附近，其穩(wěn)定性較差。這種情況下，需要我們避免不穩(wěn)定區(qū)工作即可。增大彈簧剛度法，執(zhí)行機(jī)構(gòu)抵抗負(fù)荷變化對行程影響的能力取決于彈簧剛度，剛度越大，對行程影響越小，定位器的穩(wěn)定性越好。電動高溫套筒調(diào)節(jié)閥增大彈簧剛度是提高定位器穩(wěn)定性的常見的簡單方法。調(diào)節(jié)閥相當(dāng)于控制回路中的手腳。連云港機(jī)械閥門定位器公司</p><p
