style="text-indent:25px">減溫減壓裝置的特性：實現(xiàn)降壓不消耗能量，并且該裝置可以增加蒸汽供應(yīng)。結(jié)構(gòu)簡單，無旋轉(zhuǎn)部件，運行可靠。易于操作，易于維修且可自動調(diào)節(jié)。節(jié)能效果顯著。減壓閥采用控制閥體內(nèi)的開閉部件的開度來調(diào)節(jié)介質(zhì)的流量，降低介質(zhì)的壓力，并通過調(diào)節(jié)閥的作用來調(diào)節(jié)開閉部件的開度。閥門后方的壓力，使閥門后方的壓力保持在一定范圍內(nèi)。而且在內(nèi)部，冷卻水被噴入閥體內(nèi)或閥后，以降低介質(zhì)的溫度。這種閥稱為真空減溫閥。該閥的特點是在入口壓力恒定變化的情況下，將出口壓力和溫度保持在一定范圍內(nèi)。減壓閥是氣動調(diào)節(jié)閥的重要附件。其主要功能是將氣源的壓力減壓并穩(wěn)定在一個固定值，以便調(diào)節(jié)閥可以獲得穩(wěn)定的氣源功率以進行調(diào)節(jié)控制。揚州減溫減壓裝置工廠減溫減壓裝置適合多種工作場景，可以滿足不同的需求。</p><div

style="text-indent:25px">減溫減壓裝置是現(xiàn)代工業(yè)中熱電聯(lián)產(chǎn)、集中供熱（或供汽）及輕工、電力、化工、紡織等企業(yè)，在熱能工程中應(yīng)用的一種蒸汽熱能參數(shù)（壓力、溫度）轉(zhuǎn)變裝置和利用余熱的節(jié)能裝置，通過本裝置，把用戶提供的蒸汽參數(shù)降到用戶需要合適的溫度和壓力，以滿足用戶的要求，并且能夠充分節(jié)約熱能，合理使用熱能。減溫減壓裝置工作原理裝置簡介，我國減溫減壓裝置有多種結(jié)構(gòu)形式，但不管其形式如何，一般由減溫系統(tǒng)、減壓系統(tǒng)（或減溫減壓一體系統(tǒng)）、主蒸汽管體、安全保護系統(tǒng)、熱力控制系統(tǒng)等組成。減溫減壓裝置的結(jié)構(gòu)組件由減壓閥、節(jié)流孔板、蒸汽混合管道（帶噴嘴）、安全閥、給水調(diào)節(jié)閥、節(jié)流閥、截止閥、止回閥、減溫水管、法蘭、標準件等組成。</p><p style="text-indent:25px">減溫減壓裝置在使用過程中的熱電聯(lián)產(chǎn)網(wǎng)絡(luò)可以提供區(qū)域供熱。發(fā)電廠或工業(yè)鍋爐和火力發(fā)電廠。換熱站或熱交換器的蒸汽入口。溴化鋰制冷單元的蒸汽驅(qū)動入口。減溫減壓裝置主要用于石油化工，紡織，造紙，制藥，食品和其他生產(chǎn)過程的動力和熱量。減溫減壓裝置的主要性能指標：進汽壓力，中溫和中壓：P1 <3.82 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(nèi)，并且期望在該范圍內(nèi)進行調(diào)節(jié)。如果有特殊要求。出口蒸汽溫度T2的調(diào)節(jié)精度不低于2.5級。當設(shè)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(yīng)超過85分貝。適用介質(zhì)：水，適用溫度：0℃?80℃，出口蒸汽壓力P2，出口蒸汽壓力P2的調(diào)節(jié)精度不小于2.5。減溫減壓裝置操作簡單，基本可以實現(xiàn)免維護。</p><div

style="text-indent:25px">減溫減壓裝置升壓過程中，對沖量式安全閥必須進行整定壓力校驗。當壓力升高到管道內(nèi)額定壓力的50%時，將沖量式安全閥的杠桿向上抬起，檢查主安全閥開啟和關(guān)閉動作是否靈敏，當蒸汽壓力達到規(guī)定的安全閥整定壓力時，固定并鎖緊重錘。此時，沖量安全閥應(yīng)再動作一次，檢查其整定壓力是否正常，主安全閥動作是否靈敏，有無卡阻現(xiàn)象。然后對重錘和杠桿加以鉛封或加鎖。若蒸汽管道上裝設(shè)彈簧安全閥，須對彈簧安全閥作整定壓力、回座壓力試驗，檢查其整定壓力是否正常，動作是否靈敏，有無卡阻現(xiàn)象。達到要求后，再對安全閥加以鉛封。揚州減溫減壓裝置工廠</p></p><br
