減溫減壓裝置是一種自動(dòng)降低管路工作壓力的專門裝置，它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質(zhì)主要是水。減溫減壓裝置普遍用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場合，以保證給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比，因此減溫減壓裝置具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用，據(jù)統(tǒng)計(jì)其節(jié)水效果約為30%。減溫減壓裝置的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。減溫減壓裝置的基本作用原理是靠閥內(nèi)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(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。崇明區(qū)減溫減壓裝置公司有哪些減溫減壓裝置運(yùn)行快捷，操作安全.</p><div

style="text-indent:25px">減溫減壓裝置可對電站或工業(yè)鍋爐以及熱電廠等處輸送來的蒸汽進(jìn)行減溫和減壓，使蒸汽溫度和壓力達(dá)到生產(chǎn)工藝所需的要求。減溫減壓閥是減溫減壓裝置中的關(guān)鍵部件，減溫減壓閥的性能直接影響整個(gè)減溫減壓裝置的性能。減溫的基本原理是將減溫水直接噴入過熱蒸汽，經(jīng)噴嘴霧化的減溫水從蒸汽中吸收熱量、升溫、汽化與蒸汽混合，從而達(dá)到降低蒸汽溫度的作用。為了提高蒸汽品質(zhì)，一般減溫后的蒸汽溫度應(yīng)控制在高于飽和蒸汽溫度5℃以上。減壓的工作原理是蒸汽通過減溫減壓閥（減壓閥）或節(jié)流孔板（節(jié)流罩），流通面積減少，使蒸汽動(dòng)能增加造成壓力損失，蒸汽的壓力能隨之減少而達(dá)到減壓的目的。</p><p style="text-indent:25px"> 一般而言，減溫減壓裝置在使用前都需要進(jìn)行吹洗來處理管道內(nèi)的污漬。在行業(yè)內(nèi)，吹洗措施應(yīng)經(jīng)過相關(guān)部門的批準(zhǔn)，需符合地區(qū)相關(guān)技術(shù)安穩(wěn)的規(guī)范。蒸汽管道部分用不高于減溫減壓裝置出口蒸汽壓力的蒸汽進(jìn)行吹洗;減溫水部分管路系統(tǒng)用不高于減溫水壓力的水進(jìn)行清洗。吹掃前管道須預(yù)熱和管道疏水。為了避免蒸汽管道吹洗時(shí)的污垢和雜物進(jìn)入減溫減壓閥(或減壓閥)內(nèi)，在吹掃時(shí)應(yīng)分階段進(jìn)行。先對減溫減壓裝置前面的管路吹洗，吹洗二次以上，確認(rèn)干凈后接通減溫減壓閥(或減壓閥)。減溫減壓裝置控制精度高，運(yùn)行平穩(wěn)，調(diào)節(jié)靈敏，可有效去除靜差影響。</p><div

style="text-indent:25px">減溫減壓裝置運(yùn)行前的準(zhǔn)備工作：必須檢查管道上各法蘭之間、法蘭和附件之間的連接、各閥門的啟閉、及安全閥的動(dòng)作是否正常；檢查各儀表是否完好，確認(rèn)各儀表電路已接通。關(guān)閉蒸汽進(jìn)口處的閘閥和減溫水進(jìn)口處的截止閥，用手動(dòng)操作電動(dòng)執(zhí)行器，驗(yàn)證減壓閥及給水調(diào)節(jié)閥的行程、閥門全開及全閉時(shí)的位置與電動(dòng)執(zhí)行器行程是否一致。然后確定閥門和電動(dòng)執(zhí)行器是否可投入正常運(yùn)行。運(yùn)行前，本裝置及通向用戶的管道和附件均須進(jìn)行預(yù)熱。預(yù)熱程序是：將減壓閥稍微開啟（約全行程5%），關(guān)閉減溫水進(jìn)口處的截止閥，然后慢慢地打開進(jìn)口處閘閥，輸入新蒸汽進(jìn)行預(yù)熱。預(yù)熱時(shí)蒸汽壓力應(yīng)在0.02~0.05Mpa之間，預(yù)熱時(shí)間>60分鐘。減溫減壓裝置在管道中起到一定的止回作用。甘肅減溫減壓裝置銷售價(jià)格</p><p

style="text-indent:25px">減溫減壓裝置由減溫減壓閥、過渡管及節(jié)流孔板、蒸汽管道(混合管道)、給水附件及安穩(wěn)附件組成。減壓過程通過減溫減壓閥(減壓閥)和孔板來調(diào)節(jié)蒸汽流通面積來實(shí)現(xiàn)，減溫過程是通過向蒸汽管道或減溫減壓閥內(nèi)噴水降溫來實(shí)現(xiàn)。減溫減壓閥是減溫減壓裝置中的關(guān)鍵部件，它的性能直接影響減溫減壓裝置二次蒸汽的工藝參數(shù)和裝置的使用效果及使用壽命。一般的減溫減壓閥由于采用的大多是笛型噴嘴，流量變工況時(shí)噴嘴水流速也隨之變化，特別是30%以下工況時(shí)很難滿足減溫的需要。青浦區(qū)減溫減壓裝置什么品牌比較好</p></p><br
