中(zhong)溫中(zhong)壓減溫減壓裝(zhuang)置(zhi)技術說明：

減溫減壓裝置是由哈爾濱鍋爐廠于二十世紀五十年代從前蘇聯引入國內。發展到現在，大體可分為三代產品。
第一代減溫減壓裝置為減壓、減溫分體設置：減壓系統的減壓閥多為單級柱塞式加節流孔板來完成減壓，減溫系統由節流閥、截止閥、給水調節閥或給水分配閥、止回閥、管道、混合管道、文式管等來完成減溫；該結構形式的減溫減壓裝置的缺點是結構復雜，占地面積大，安裝維修不方便，調節范圍窄，噪音高、故障率高等；同時管道內容易積水造成水擊現象，引起振動，降低使用壽命。
第二代減溫減壓裝置為減壓減溫一體完成：在第一代的基礎上管將管道上的減溫水噴咀移到減壓閥上部或下部使之成為減溫減壓閥和節流孔板進行節流減壓；省去了第一代結構中的減溫水管道，從而減少了占地面積、減化了結構、方便了安裝與維修、減少了故障、避免了管道內的水擊現象提高了裝置的使用壽命。缺點是減溫減壓閥只是在原減壓閥的基礎上加入噴咀，其內部結構形式沒有變化，減溫系統也沒有變化。
第三代減(jian)(jian)溫(wen)減(jian)(jian)壓裝(zhuang)置為第二代的(de)換代產品(pin)：減(jian)(jian)溫(wen)減(jian)(jian)壓閥(fa)內(nei)(nei)部(bu)改為多級套筒(tong)式(shi)省去了(le)節(jie)流孔板(ban)，同時多級套筒(tong)的(de)節(jie)流小孔還起到消音的(de)作用(yong)。減(jian)(jian)溫(wen)減(jian)(jian)壓閥(fa)與給(gei)水調(diao)節(jie)閥(fa)采(cai)用(yong)德(de)國(guo)(guo)西門子公(gong)司(si)、梅索(suo)尼蘭(lan)公(gong)司(si)和(he)菲希爾(er)公(gong)司(si)變流量(liang)系(xi)數設計的(de)方法(fa)，目前在(zai)(zai)國(guo)(guo)內(nei)(nei)只(zhi)有我(wo)公(gong)司(si)一家(jia)采(cai)用(yong)此方法(fa)進行設計。該(gai)設計形(xing)式(shi)的(de)特點就是設計與使用(yong)相吻合，從0到100%全程(cheng)可(ke)調(diao)節(jie)，該(gai)設計方法(fa)于(yu)2003年12月(yue)被國(guo)(guo)家(jia)科委(wei)授予(yu)應用(yong)型(xing)發明獎(jiang)。由于(yu)給(gei)水調(diao)節(jie)閥(fa)能夠適用(yong)于(yu)各種(zhong)壓差(cha)，在(zai)(zai)減(jian)(jian)溫(wen)系(xi)統中取消了(le)節(jie)流閥(fa)或節(jie)流裝(zhuang)置。第三代產品(pin)不僅具備第二代產品(pin)的(de)所有優點，同時還彌補(bu)第二代產品(pin)中的(de)所有不足之處(chu)：1、減(jian)(jian)壓，并多級同步(bu)(bu)調(diao)節(jie)提(ti)高(gao)了(le)調(diao)節(jie)范圍；2、采(cai)用(yong)同步(bu)(bu)可(ke)調(diao)噴咀在(zai)(zai)閥(fa)內(nei)(nei)噴水，提(ti)高(gao)了(le)霧化效果。
