減溫(wen)減壓(ya)裝(zhuang)置(zhi)(zhi)的(de)工作原理：減溫(wen)減壓(ya)裝(zhuang)置(zhi)(zhi)的(de)結構形(xing)式(shi)很多，但無論其(qi)形(xing)式(shi)如何，一(yi)般都由降溫(wen)系(xi)統、減壓(ya)系(xi)統（或降溫(wen)減壓(ya)系(xi)統）和主蒸汽(qi)管(guan)體(ti)、安全(quan)保護(hu)系(xi)統、熱(re)控(kong)系(xi)統等幾(ji)部分組(zu)成。減溫(wen)減壓(ya)裝(zhuang)置(zhi)(zhi)的(de)結構部件由減壓(ya)閥(fa)、節流孔、混汽(qi)管(guan)（帶噴嘴）、安全(quan)閥(fa)、供水 調(diao)節閥、節流閥、截止(zhi)閥、止(zhi)回閥、減(jian)壓水管、法蘭、標準件(jian)等。
1、降溫系統(tong)：冷卻(que)水通過(guo)高(gao)壓差調節(jie)閥(fa)（或(huo)變頻水泵等）從不同形式的噴嘴(zui)以(yi)霧狀(zhuang)噴入文丘(qiu)里(li)管或(huo)蒸(zheng)汽(qi)管的蒸(zheng)汽(qi)中(zhong)，以(yi)降低(di)蒸(zheng)汽(qi)溫度(du)。
2、減(jian)壓(ya)系統：由減(jian)壓(ya)閥和孔(kong)板(ban)組(zu)成(cheng)。減(jian)壓(ya)閥通(tong)過改(gai)變流通(tong)面積來(lai)達到調(diao)節壓(ya)力的(de)目(mu)的(de)。
3、降(jiang)溫(wen)減壓(ya)系統(tong)：降(jiang)溫(wen)系統(tong)和減壓(ya)系統(tong)合二(er)為一，減小了減溫(wen)減壓(ya)裝置的(de)整體尺寸，增加了技術復雜度(du)。
4、主蒸汽(qi)(qi)管(guan)體(ti)：由混合管(guan)和蒸汽(qi)(qi)管(guan)組成(cheng)。根據用戶(hu)提供的(de)參數確定，是減(jian)溫(wen)減(jian)壓裝置的(de)主要(yao)設備，目的(de)是將降溫(wen)減(jian)壓后的(de)蒸汽(qi)(qi)送(song)入用戶(hu)所需的(de)管(guan)道中。
5、減溫減壓(ya)裝置(zhi)安(an)全(quan)(quan)系統：為防(fang)止二次蒸汽(qi)(qi)壓(ya)力超過規定值，自動開啟(qi)安(an)全(quan)(quan)閥(fa)排出多余蒸汽(qi)(qi)，從(cong)而達到減壓(ya)和(he)安(an)全(quan)(quan)保護的功能。
減壓(ya)系(xi)統采用(yong)雙閥(fa)座減壓(ya)閥(fa)結構，不(bu)平衡力小，調(diao)節范圍大，動作平穩(wen)，無卡阻。 減(jian)(jian)(jian)(jian)溫(wen)(wen)系統(tong)(tong)采(cai)用(yong)文丘(qiu)里管式噴嘴(zui)方(fang)式，無傳動部件，減(jian)(jian)(jian)(jian)溫(wen)(wen)水霧(wu)化效果好，噴嘴(zui)拆裝(zhuang)方(fang)便，減(jian)(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)(jian)壓(ya)(ya)裝(zhuang)置維修(xiu)方(fang)便。減(jian)(jian)(jian)(jian)壓(ya)(ya)系統(tong)(tong)與減(jian)(jian)(jian)(jian)溫(wen)(wen)系統(tong)(tong)分離(li)，主要(yao)用(yong)于惡劣工況，如(ru)蒸(zheng)汽(qi)流量低(di)，不適(shi)合(he)使用(yong)減(jian)(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)(jian)壓(ya)(ya)閥，飽和蒸(zheng)汽(qi)（低(di)壓(ya)(ya)）工況。減(jian)(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)(jian)壓(ya)(ya)裝(zhuang)置主要(yao)采(cai)用(yong)文丘(qiu)里管減(jian)(jian)(jian)(jian)溫(wen)(wen)方(fang)式，減(jian)(jian)(jian)(jian)溫(wen)(wen)水充分霧(wu)化，達到(dao)更好的(de)減(jian)(jian)(jian)(jian)溫(wen)(wen)效果
