1）因采用機(jī)械式力平衡原理工作，其可動(dòng)部件較多，容易受溫度，振動(dòng)的影響，造成調(diào)節(jié)閥的波動(dòng)； 2）采用噴嘴擋板技術(shù)，由于噴嘴孔很小，易被灰塵或不干凈的氣源堵住，是定位器不能正常工作； 3）采用力的平衡原理，彈簧的彈性系數(shù)在惡劣現(xiàn)場(chǎng)下發(fā)生改變，造成調(diào)節(jié)閥非線性導(dǎo)致控制質(zhì)量下降。 5.2智能定位器由微處理器（cpu）、A/D,D/A轉(zhuǎn)換器及等部件組成，其工作原理與普通定位器截然不同。給定值和實(shí)際值的比較純是電動(dòng)信號(hào)，不再是力平衡。因此能夠克服常規(guī)定位器的力平衡的缺點(diǎn)。但在用于緊急停車場(chǎng)合時(shí)，如緊急切斷閥、緊急放空閥等。這些閥門要求靜止在某一位置，只有緊急情況出現(xiàn)時(shí)，才需要可靠地動(dòng)作。長(zhǎng)時(shí)間停留在某一位置容易使電氣轉(zhuǎn)換器失控造成小信號(hào)不動(dòng)作的危險(xiǎn)情況。此外用于閥門的位置傳感電位器由于工作在現(xiàn)場(chǎng)，電阻值易發(fā)生變化造成小信號(hào)不動(dòng)作，大信號(hào)全開的危險(xiǎn)情況。因此為了確保智能定位器的可靠性和可利用性，必須對(duì)它們進(jìn)行頻繁的測(cè)試。低噪音套筒調(diào)節(jié)閥作用有哪些為了使調(diào)節(jié)閥正常工作，配用的執(zhí)行機(jī)構(gòu)要能產(chǎn)生足夠的輸出力來(lái)保證高度密封和閥門的開啟。</p><div
