減(jian)(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)(jian)壓(ya)裝置的(de)工作原理：減(jian)(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)(jian)壓(ya)裝置的(de)結構形式很多，但(dan)無論其形式如何，一(yi)般都由(you)降(jiang)溫(wen)系(xi)(xi)統(tong)(tong)(tong)、減(jian)(jian)(jian)(jian)壓(ya)系(xi)(xi)統(tong)(tong)(tong)（或(huo)降(jiang)溫(wen)減(jian)(jian)(jian)(jian)壓(ya)系(xi)(xi)統(tong)(tong)(tong)）和主蒸汽(qi)管(guan)體、安(an)全保護系(xi)(xi)統(tong)(tong)(tong)、熱控系(xi)(xi)統(tong)(tong)(tong)等幾部分組成。減(jian)(jian)(jian)(jian)溫(wen)減(jian)(jian)(jian)(jian)壓(ya)裝置的(de)結構部件(jian)由(you)減(jian)(jian)(jian)(jian)壓(ya)閥、節(jie)流孔(kong)、混汽(qi)管(guan)（帶(dai)噴嘴）、安(an)全閥、供水 調(diao)節閥、節流閥、截(jie)止閥、止回閥、減壓(ya)水管、法蘭(lan)、標準(zhun)件等。
1、降(jiang)溫(wen)系統(tong)：冷卻水通過高(gao)壓差調(diao)節閥（或(huo)變頻(pin)水泵等）從(cong)不同形式(shi)的(de)噴(pen)嘴以霧狀噴(pen)入文丘里管或(huo)蒸汽(qi)(qi)管的(de)蒸汽(qi)(qi)中(zhong)，以降(jiang)低蒸汽(qi)(qi)溫(wen)度(du)。
2、減(jian)壓(ya)(ya)(ya)系(xi)統：由減(jian)壓(ya)(ya)(ya)閥和孔板組成。減(jian)壓(ya)(ya)(ya)閥通(tong)(tong)過改變流通(tong)(tong)面積來達到調節壓(ya)(ya)(ya)力的目的。
3、降(jiang)溫(wen)減(jian)壓系統(tong)：降(jiang)溫(wen)系統(tong)和(he)減(jian)壓系統(tong)合二為一，減(jian)小(xiao)了減(jian)溫(wen)減(jian)壓裝置的(de)整體尺寸，增加(jia)了技術(shu)復雜度(du)。
4、主蒸(zheng)(zheng)汽(qi)(qi)管(guan)體(ti)：由混(hun)合管(guan)和蒸(zheng)(zheng)汽(qi)(qi)管(guan)組成。根(gen)據用戶提供的(de)(de)(de)參數確定，是減溫減壓裝置(zhi)的(de)(de)(de)主要(yao)設(she)備，目(mu)的(de)(de)(de)是將降溫減壓后的(de)(de)(de)蒸(zheng)(zheng)汽(qi)(qi)送(song)入用戶所需的(de)(de)(de)管(guan)道(dao)中。
5、減(jian)(jian)溫減(jian)(jian)壓裝置安全系統：為防止二次蒸汽(qi)壓力超過規定值，自動(dong)開(kai)啟安全閥排出多余蒸汽(qi)，從而(er)達到(dao)減(jian)(jian)壓和(he)安全保護(hu)的(de)功能。
減(jian)壓(ya)系統采(cai)用雙閥(fa)(fa)座(zuo)減(jian)壓(ya)閥(fa)(fa)結構(gou)，不平衡力小，調節范(fan)圍大，動作(zuo)平穩(wen)，無卡阻。 減(jian)(jian)溫(wen)(wen)系(xi)統(tong)(tong)采用(yong)(yong)(yong)文丘里(li)管式(shi)(shi)噴嘴方(fang)式(shi)(shi)，無傳動部(bu)件，減(jian)(jian)溫(wen)(wen)水霧(wu)化效(xiao)果好(hao)，噴嘴拆裝(zhuang)方(fang)便，減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)裝(zhuang)置維修(xiu)方(fang)便。減(jian)(jian)壓(ya)(ya)系(xi)統(tong)(tong)與(yu)減(jian)(jian)溫(wen)(wen)系(xi)統(tong)(tong)分離，主(zhu)要(yao)用(yong)(yong)(yong)于(yu)惡劣工況(kuang)，如蒸汽流量(liang)低，不適合使(shi)用(yong)(yong)(yong)減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)閥，飽和(he)蒸汽（低壓(ya)(ya)）工況(kuang)。減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)(ya)裝(zhuang)置主(zhu)要(yao)采用(yong)(yong)(yong)文丘里(li)管減(jian)(jian)溫(wen)(wen)方(fang)式(shi)(shi)，減(jian)(jian)溫(wen)(wen)水充(chong)分霧(wu)化，達(da)到更好(hao)的減(jian)(jian)溫(wen)(wen)效(xiao)果
