style="text-indent:25px">閥門(mén)定位器操作時(shí)的啟閉方向，一律應(yīng)順時(shí)針關(guān)閉。由于管網(wǎng)中的氣動(dòng)閥，經(jīng)常是人工啟閉，啟閉轉(zhuǎn)數(shù)不宜過(guò)多，就是大口徑閥門(mén)亦應(yīng)在200-600轉(zhuǎn)內(nèi)。為了便于一個(gè)人的啟閉操作，在管道工壓狀況下，啟閉力矩宜為240N-m。閥門(mén)定位器啟閉操作端應(yīng)為方榫，且尺寸標(biāo)準(zhǔn)化，并面向地面，以便人們從地面上可直接操作。帶輪盤(pán)的閥門(mén)不適用于地下管網(wǎng)。閥門(mén)定位器啟閉程度的顯示盤(pán)，閥門(mén)定位器啟閉程度的刻度線(xiàn)，應(yīng)鑄造在變速箱蓋上或轉(zhuǎn)換方向后的顯示盤(pán)的外殼上，一律面向地面，刻度線(xiàn)刷上熒光粉，以示醒目。</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(mén)通徑從1mm到600mm，甚至達(dá)到9750mm；工作溫度從**溫-269°C到高溫1200°C，甚至高達(dá)3430°C；閥門(mén)的驅(qū)動(dòng)方式從手動(dòng)發(fā)展到電動(dòng)、氣動(dòng)、液動(dòng)、程控、數(shù)控、遙控；閥門(mén)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(zhǎng)，像一個(gè)現(xiàn)代化的石油化工裝置就需要上萬(wàn)只各式各樣的閥門(mén),閥門(mén)使用量大。但往往由于制造、使用選型、維修不當(dāng)，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。定位器有手動(dòng)和自動(dòng)之分，各自的效用也是不一樣的。天津電器閥門(mén)定位器廠家排行</p><p style="text-indent:25px">定位器具有豐富的自診斷功能。天津電器閥門(mén)定位器廠家排行</p><p style="text-indent:25px">溫度條件:閥門(mén)定位器使用溫度在規(guī)定溫度之外，密封材料會(huì)迅速降解，定位器不能正常工作，需要在規(guī)定溫度范圍內(nèi)使用。清洗:使用清潔氣體去除閥門(mén)定位器上的水分和灰塵。根據(jù)閥門(mén)要求的扭矩，確定電動(dòng)執(zhí)行機(jī)構(gòu)的輸出扭矩，閥門(mén)開(kāi)啟和關(guān)閉所需的扭矩決定了電動(dòng)執(zhí)行機(jī)構(gòu)所選擇的輸出扭矩。一般由用戶(hù)提出或閥門(mén)廠家選用。由于執(zhí)行機(jī)構(gòu)制造商只負(fù)責(zé)執(zhí)行機(jī)構(gòu)的輸出扭矩，所以需要閥門(mén)正常開(kāi)啟和關(guān)閉。扭矩是由閥口徑等因素決定的,工作壓力,等等,但由于加工精度和裝配過(guò)程的差異的閥門(mén)制造商,閥門(mén)所需的轉(zhuǎn)矩相同規(guī)格的由不同的制造商也不同,即使它們是由相同的閥門(mén)制造商。閥門(mén)的扭矩也不同。當(dāng)選擇的執(zhí)行機(jī)構(gòu)太小時(shí)，閥門(mén)無(wú)法正常啟閉，所以電動(dòng)執(zhí)行機(jī)構(gòu)須選擇合理的扭矩范圍。天津電器閥門(mén)定位器廠家排行</p></p><br
