style="text-indent:25px">減溫減壓裝置介質節(jié)流通道為雙座形式，流通面積大，閥桿節(jié)流處堆焊硬質合金，閥桿材料多為不銹鋼或氮化鋼，經過數十年考驗，雙座減壓閥只要在上述參數范圍內使用，沒有發(fā)生過異常問題。雙座閥不平衡力小、調節(jié)范圍廣、動作平穩(wěn)，不會出現卡死現象。減壓閥密封表面堆焊鈷基ERCrMn-C-15，抗高溫、抗沖刷；閥座和閥瓣采用配合研磨，密封性能好。柱塞式單座減壓閥，多用于壓力≤9.8MPa、溫度≥4500C或更高參數。該閥屬引進改進型產品，閥桿、閥瓣為一整體，在閥瓣處開具多個能將汽流分解成多股梅花狀流道。</p><p style="text-indent:25px">減溫減壓裝置特點：減壓系統(tǒng)采用雙閥座減壓閥結構，不平衡力小，調節(jié)范圍大，動作平穩(wěn)，無卡阻現象。減溫系統(tǒng)采用文丘里氏加笛管噴嘴的方式，無傳動部件，減溫水霧化效果好，噴嘴拆裝方便，便于維修。減壓系統(tǒng)和減溫系統(tǒng)分開，主要用于工況惡劣，如蒸汽流量小不適用采用減溫減壓閥的，及飽和蒸汽的工況(壓力較低主要考慮蒸汽流速較低)采用文丘里管減溫方式，減溫水充分霧化，以達到較好的減溫效果。減溫減壓裝置的供貨范圍為標志以內，使用的范圍是很廣闊的。減溫減壓裝置動作平穩(wěn)，不會出現卡阻現象；</p><div

style="text-indent:25px">減溫減壓裝置的作用原理是靠閥內流道對水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側的進口水壓差自動調節(jié)。定比減壓原理是利用閥體中浮動活塞的水壓比控制，進出口端減壓比與進出口側活塞面積比成反比。這種減溫減壓裝置工作平穩(wěn)無振動；閥體內無彈簧，故無彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，因而既減動壓（水流動時）又減靜壓（流量為0）時；特別是在減壓的同時不影響水流量。這就是減溫減壓裝置的作用和工作原理，是一種常見的工作生產裝置。減溫減壓裝置應先測量閥門扭矩，并且扭矩不得超過要求的扭矩。宿州減溫減壓裝置銷售價格</p><p
