style="text-indent:25px">定位器具體的作用包括以下這幾點。①定位器一般用于對調(diào)節(jié)質(zhì)量要求很高的調(diào)節(jié)系統(tǒng)中，主要是為了提高調(diào)節(jié)閥定位和可靠性。也就是說使用了定位器的調(diào)節(jié)閥的定位的精確度和可靠性會的提高。②如果閥門的兩端的差距比較大的話，可應(yīng)通過使用閥門調(diào)節(jié)器來調(diào)節(jié)。提高了氣源壓力增大執(zhí)行機構(gòu)的輸出力之后，可以減輕不平衡里，減少行程上產(chǎn)生的誤差。③被調(diào)節(jié)的介質(zhì)如果具備高溫、高壓、有毒、易爆等特性的話，一定要想辦法防止它外漏。一般為了防止外漏會采用將填料壓的很緊的做法，這樣會產(chǎn)生閥桿和填料之間產(chǎn)生很大的摩擦力，想要克服這種摩擦力就要使用定位器了。無錫電動密閉閥門定位器定位器在工作時可以保證調(diào)節(jié)閥的正確定位。</p><div

style="text-indent:25px">定位器排出的空氣無法再用只能排大氣，這是定位器的主要耗氣。另外定位器除了智能式的以外，都有一依據(jù)氣動儀表原理工作的部分，其工作動力來自氣源，通過將帶壓氣體減壓所釋放的功來驅(qū)動，也要消耗一定氣量?！巴ㄟ^將帶壓氣體減壓所釋放的功來驅(qū)動，也要消耗一定氣量?！笔侵笟鈩觾x表內(nèi)部工作時用以推動各種膜片、活塞、杠桿運動的各個工作腔室的壓力定位，都是用過有控制的將輸入的壓縮空氣向大氣排放而獲得的。這也是即使在靜止狀態(tài)下，定位器也一直有氣體排出的原因。</p><p style="text-indent:25px">定位器其工作壓力從超真空1.33x10-8Mpa(1x10-1mmHg)到超高壓1460MPa，閥門通徑從1mm到600mm，甚至達到9750mm；工作溫度從**溫-269°C到高溫1200°C，甚至高達3430°C；閥門的驅(qū)動方式從手動發(fā)展到電動、氣動、液動、程控、數(shù)控、遙控；閥門的材料從鑄鐵，碳素鋼發(fā)展到鈦及鈦合金，**度耐腐蝕鋼等。隨著現(xiàn)代工業(yè)的不斷發(fā)展，定位器需求量不斷增長，像一個現(xiàn)代化的石油化工裝置就需要上萬只各式各樣的閥門,閥門使用量大。但往往由于制造、使用選型、維修不當，引起儀器的故障，或者造成產(chǎn)品質(zhì)量低劣，能耗提高，設(shè)備腐蝕，物耗提高，環(huán)境污染，甚至造成停產(chǎn)等事故。定位器可以安裝在直行程和旋轉(zhuǎn)式執(zhí)行機構(gòu)上。</p><div
