style="text-indent:25px">減溫減壓裝置是由哈爾濱鍋爐廠于二十世紀五十年代從前蘇聯(lián)引入國內(nèi)。發(fā)展到現(xiàn)在，大體可分為三代產(chǎn)品。第三代減溫減壓裝置為第二代的換代產(chǎn)品：減溫減壓閥內(nèi)部改為多級套筒式省去了節(jié)流孔板，同時多級套筒的節(jié)流小孔還起到消音的作用。減溫減壓閥與給水調(diào)節(jié)閥采用變流量系數(shù)設計的方法。該設計形式的特點就是設計與使用相吻合，從0到100%全程可調(diào)節(jié)，該設計方法于2003年12月被國家科委授予應用型發(fā)明獎。由于給水調(diào)節(jié)閥能夠適用于各種壓差，在減溫系統(tǒng)中取消了節(jié)流閥或節(jié)流裝置。第三代產(chǎn)品不僅具備第二代產(chǎn)品的所有優(yōu)點，同時還彌補第二代產(chǎn)品中的所有不足之處：減壓，并多級同步調(diào)節(jié)提高了調(diào)節(jié)范圍；采用同步可調(diào)噴咀在閥內(nèi)噴水，提高了霧化效果。</p><p

style="text-indent:25px">運行前減溫減壓裝置及通向用戶的管道部件須預熱，以防止這些部件和零件產(chǎn)生附加應力。預熱前，先將減溫減壓閥稍微開啟（約開啟總行程的2%），然后將切斷閥（減溫減壓閥前面）慢慢打開，利用入口蒸汽預熱減溫減壓閥、蒸汽管道、及通向用戶的管道和附件。預熱時蒸汽壓力不超過0.02~0.05Mpa，預熱時間根據(jù)整個裝置以及總長度來決定，但不能少于30分鐘。同時檢查給水壓力是否正常，如正常，可慢慢打開給水系統(tǒng)的截止閥和節(jié)流閥。減溫減壓裝置停止工作時，應預先通告鍋爐房及用戶。先逐漸關閉入口處切斷閥，然后手動關閉減壓閥和給水調(diào)節(jié)閥，使蒸汽壓力和溫度漸漸降低，即時逐漸打開通往排水管的截止閥，使減溫水排放通暢。確認斷汽后，關閉出口處切斷閥，再檢查入口處切斷閥關閉是否嚴密。吉林減溫減壓裝置價格是多少</p></p><br
