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(duì)行程影響的能力取決于彈簧剛度，剛度越大，對(duì)行程影響越小，定位器的穩(wěn)定性越好。電動(dòng)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(jiǎn)單方法。南通一體式閥門定位器有哪些被調(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。</p><div
