style="text-indent:25px">減溫減壓裝置在使用時注意：薄膜式減溫減壓裝置，適用于低壓、中壓、中小口徑的蒸汽或水等介質(zhì)；減溫減壓裝置進口壓力的波動應(yīng)控制在進口壓力給定值的80%～105%，如超過該范圍，減壓前期的性能會受影響；通常減溫減壓裝置的閥后壓力應(yīng)小于閥前壓力的0.5倍；減溫減壓裝置的每一檔彈簧只在一定的出口壓力范圍內(nèi)適用，超出范圍應(yīng)更換彈簧；在介質(zhì)工作溫度比較高的場合，一般選用先導(dǎo)活塞式減溫減壓裝置或先導(dǎo)波紋管式減溫減壓裝置；介質(zhì)為空氣或水（液體）的場合，一般宜選用直接作用薄膜式減溫減壓裝置或先導(dǎo)薄膜式減溫減壓裝置；介質(zhì)為蒸汽的場合，宜選用先導(dǎo)活塞式或先導(dǎo)波紋管式減溫減壓裝置；為了操作、調(diào)整和維修的方便，減溫減壓裝置一般應(yīng)安裝在水平管道上。</p><p style="text-indent:25px">加強減溫減壓裝置保障系統(tǒng)的管理巡視，要注意觀察減溫減壓裝置本身的工作動態(tài)。閥前、閥后壓力數(shù)值接近，表明減溫減壓裝置本身已存在故障。即活塞式減溫減壓裝置的閥芯與閥體間的平面密封橡膠件損壞；薄膜式可調(diào)型減溫減壓裝置主閥膜片有裂痕和O型圈損壞，及導(dǎo)閥連通管堵塞，造成減溫減壓裝置減壓作用削弱或者失效。這對分區(qū)管網(wǎng)危害極大，特別是許多用水設(shè)備可能因超壓力而出現(xiàn)爆管，必須及時修復(fù)。比例式(活塞型)減溫減壓裝置閥體上的透吸氣小孔如出現(xiàn)滴漏不止，表明閥芯上幾檔O型密封圈已經(jīng)磨損，要更換密封件。減溫減壓裝置能夠充分節(jié)約熱能，合理使用熱能。</p><div
