減(jian)(jian)(jian)溫減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置的工作(zuo)原理：減(jian)(jian)(jian)溫減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置的結構(gou)形式(shi)很多，但無論其形式(shi)如(ru)何，一般(ban)都由(you)降溫系(xi)統(tong)、減(jian)(jian)(jian)壓(ya)系(xi)統(tong)（或降溫減(jian)(jian)(jian)壓(ya)系(xi)統(tong)）和主蒸汽管體、安全保(bao)護系(xi)統(tong)、熱(re)控系(xi)統(tong)等幾部(bu)分組成。減(jian)(jian)(jian)溫減(jian)(jian)(jian)壓(ya)裝(zhuang)(zhuang)置的結構(gou)部(bu)件由(you)減(jian)(jian)(jian)壓(ya)閥、節流孔、混汽管（帶噴嘴）、安全閥、供水 調節閥(fa)、節流(liu)閥(fa)、截止閥(fa)、止回閥(fa)、減壓水管、法蘭、標(biao)準件等。
1、降溫(wen)系統：冷卻水通過高(gao)壓(ya)差調節(jie)閥（或變(bian)頻水泵(beng)等）從不(bu)同(tong)形式的(de)(de)噴(pen)嘴以霧(wu)狀噴(pen)入文丘里(li)管(guan)或蒸汽(qi)(qi)管(guan)的(de)(de)蒸汽(qi)(qi)中，以降低(di)蒸汽(qi)(qi)溫(wen)度。
2、減(jian)壓(ya)(ya)系(xi)統(tong)：由減(jian)壓(ya)(ya)閥(fa)和孔板(ban)組成。減(jian)壓(ya)(ya)閥(fa)通過(guo)改(gai)變流通面積來達到調(diao)節壓(ya)(ya)力的(de)目的(de)。
3、降溫(wen)減(jian)壓系(xi)統(tong)：降溫(wen)系(xi)統(tong)和減(jian)壓系(xi)統(tong)合(he)二為一(yi)，減(jian)小了(le)減(jian)溫(wen)減(jian)壓裝置的整體(ti)尺寸，增加了(le)技術(shu)復雜度。
4、主蒸(zheng)(zheng)汽(qi)管(guan)體：由(you)混合(he)管(guan)和(he)蒸(zheng)(zheng)汽(qi)管(guan)組成(cheng)。根據用戶提供的(de)參數確定，是減溫(wen)減壓(ya)裝置的(de)主要設備，目的(de)是將降溫(wen)減壓(ya)后的(de)蒸(zheng)(zheng)汽(qi)送入用戶所需的(de)管(guan)道中。
5、減溫減壓(ya)裝置安(an)全(quan)系統：為防(fang)止二次蒸汽壓(ya)力超過規定值(zhi)，自動(dong)開啟(qi)安(an)全(quan)閥排出多(duo)余蒸汽，從而(er)達到減壓(ya)和安(an)全(quan)保(bao)護(hu)的功(gong)能。
減壓系統采用(yong)雙閥座減壓閥結構，不平衡(heng)力小(xiao)，調節范圍大，動作平穩，無卡阻。 減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)系(xi)統(tong)(tong)采(cai)用文丘(qiu)里管(guan)式(shi)噴嘴(zui)(zui)方式(shi)，無傳動部件，減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)水霧(wu)化(hua)效(xiao)果(guo)好，噴嘴(zui)(zui)拆(chai)裝(zhuang)方便(bian)(bian)，減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)(jian)(jian)(jian)壓裝(zhuang)置維修方便(bian)(bian)。減(jian)(jian)(jian)(jian)(jian)壓系(xi)統(tong)(tong)與減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)系(xi)統(tong)(tong)分離，主要(yao)用于惡劣工況(kuang)(kuang)，如蒸(zheng)汽流量低(di)，不(bu)適(shi)合使用減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)(jian)(jian)(jian)壓閥，飽(bao)和蒸(zheng)汽（低(di)壓）工況(kuang)(kuang)。減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)減(jian)(jian)(jian)(jian)(jian)壓裝(zhuang)置主要(yao)采(cai)用文丘(qiu)里管(guan)減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)方式(shi)，減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)水充分霧(wu)化(hua)，達到更好的減(jian)(jian)(jian)(jian)(jian)溫(wen)(wen)(wen)效(xiao)果(guo)
