MPa，溫度：T1 <450°C。亞高溫高壓：P1 <5.4Mpa，溫度：T1 <485°C。減壓裝置的溫度和出口流量Q在10%Q至100%Q的范圍內，并且期望在該范圍內進行調節(jié)。如果有特殊要求。出口蒸汽溫度T2的調節(jié)精度不低于2.5級。當設備正常工作時，冷卻減壓閥下游一米處和距管壁一米處的噪聲不應超過85分貝。適用介質：水，適用溫度：0℃?80℃，出口蒸汽壓力P2，出口蒸汽壓力P2的調節(jié)精度不小于2.5。減壓裝置批發(fā)報價減溫減壓裝置功能強大，并可根據用戶要求進行功能擴展。</p><div

style="text-indent:25px">減溫減壓裝置主要用于供熱系統(tǒng)，可對電站或工業(yè)鍋爐以及熱電廠等處送來的蒸汽的壓力、溫度降低到用戶所需的蒸汽參數(shù)。減溫減壓裝置根據需要分為減溫減壓裝置、減溫裝置、減壓裝置。按蒸汽參數(shù)的高低又可分為中溫中壓、次高壓和高溫高壓減溫減壓裝置。應用：熱電聯(lián)產熱網集中供熱。電站或工業(yè)鍋爐以及熱電廠。熱交換站或換熱器蒸汽進口。溴化鋰制冷機組蒸汽動力入口。石化、輕紡、造紙、制藥、食品等生產工藝設備動力及用熱。、減溫減壓裝置的安全保護系統(tǒng)：采用彈簧安全閥（或主安全閥）來實現(xiàn)安全保護。當管道內蒸汽壓力超過允許值時，安全閥即自動開啟排除蒸汽。當壓力恢復至規(guī)定值時，安全閥即自動關閉。使二次蒸汽壓力保持在允許值內，保證設備和管路的安全運行。減溫減壓裝置的熱力調節(jié)系統(tǒng)：實現(xiàn)對電動減溫減壓閥和電動調節(jié)閥的控制，有自動控制、遠程遙控或現(xiàn)場手動控制等多種形式。</p><p

℃；減溫水的壓力Pb MPa；減溫水的壓力Tb ℃；執(zhí)行機構形式：電動/氣動（明確品牌，氣動還需要明確進氣開or進氣關）；給水路上的閥門是否有特殊要求（其實就是那個截止閥）。若要電動的也要提一下電裝的要求（品牌、想要實現(xiàn)怎么樣的功能）；明確裝置進出口是否要配切斷閥，配的話也要提出相應的要求；若裝置上還有另外特殊的要求，如要小旁路什么的也盡可能詳細提出，這些石油化工上的要求比較多。。安裝每個閥時，請注意蒸汽和減溫水的流向。減壓裝置批發(fā)報價</p><p
