style="text-indent:25px">減溫減壓裝置顧名思義:后面的溫度和壓力肯定要比前面的低。減溫減壓裝置的介質一定是蒸汽。明確了這兩點后，我們就可以提要求采購設備了，采購減溫減壓裝置需要提供七個參數(shù)+注意事項：裝置進口/出口蒸汽的蒸汽流量Q t/h；裝置進口蒸汽的壓力P1 MPa；裝置進口蒸汽的溫度T1 ℃；裝置出口蒸汽的壓力P2 MPa；裝置出口蒸汽的溫度T2 ℃；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。。減溫減壓裝置在組裝后要進行測試。</p><div

style="text-indent:25px">減溫減壓裝置的使用現(xiàn)在已經是非常多了，其中對于減壓閥的維修與檢查是很重要的，那么主要都有哪些檢查部位?減壓閥的檢修用刷子去除閥門外部的鐵銹;在閥體和閥蓋上做標記，以防止在組裝過程中發(fā)生未對準，然后將閥稍微打開或打開;拆下變速箱;松開門蓋的螺栓，然后提起門蓋;拆下閥瓣并將其保存在安全的地方;取下填料壓蓋螺母并退出填料壓蓋;拆下閥帽螺母，拆下閥帽，拆下填料;擰開閥桿，并拆下填料函中的填料;拆下螺紋套筒和平面軸承，用煤油清洗，用棉紗擦干，然后拆下螺栓，其他零件也應清洗并妥善保管;拆下門蓋墊片，并檢查門蓋接合面。減溫減壓裝置使用的減溫水必須是純凈軟化水，不得帶有固體雜質以防堵塞噴嘴。浙江減溫減壓裝置批發(fā)多少錢</p><p style="text-indent:25px">減溫減壓裝置維護的成本是很低的，幾乎可以不計算。浙江減溫減壓裝置批發(fā)多少錢</p><p style="text-indent:25px">減溫減壓裝置由兩個**作用的止回閥和泄水閥組成，能嚴格限定管道中的壓力水只能單向流動的水力控制裝置。減壓閥開啟泄壓，減壓閥又關閉。當閥后管網(wǎng)壓力升高，超過閥前進口壓力時，如出口位置上的止回閥密封完好無泄漏，高壓水不會倒流，隔膜左右保持原來的壓差，減壓閥關閉不泄漏。當出口位置上的止回閥密封破壞造成滲漏，出口位置上的止回閥之前壓力升高，造成減壓閥隔膜左右壓差減小，減壓閥打開通過排水口泄壓。用調壓彈簧直接調壓，則彈簧剛度必然過大，流量變化時，輸出壓力波動較大，閥的結構尺寸也將增大。為了克服這些缺點，可采用減溫減壓裝置。浙江減溫減壓裝置批發(fā)多少錢</p></p><br
