減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)裝置的(de)(de)工作原理：減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)裝置的(de)(de)結構(gou)形式(shi)很多(duo)，但無論(lun)其形式(shi)如何，一般都由降溫(wen)(wen)系(xi)(xi)(xi)統(tong)、減(jian)(jian)壓(ya)系(xi)(xi)(xi)統(tong)（或降溫(wen)(wen)減(jian)(jian)壓(ya)系(xi)(xi)(xi)統(tong)）和主蒸(zheng)汽(qi)管體(ti)(ti)、安全保護系(xi)(xi)(xi)統(tong)、熱(re)控系(xi)(xi)(xi)統(tong)等幾部(bu)分組成。減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓(ya)裝置的(de)(de)結構(gou)部(bu)件(jian)由減(jian)(jian)壓(ya)閥(fa)、節流(liu)孔、混汽(qi)管（帶噴嘴(zui)）、安全閥(fa)、供水(shui) 調節(jie)閥(fa)、節(jie)流閥(fa)、截止閥(fa)、止回閥(fa)、減壓(ya)水管、法蘭、標準(zhun)件等。
1、降溫系統：冷(leng)卻(que)水(shui)通過高(gao)壓差調(diao)節(jie)閥（或變頻(pin)水(shui)泵等）從(cong)不同形式的噴嘴以(yi)霧(wu)狀噴入文丘里管或蒸汽(qi)(qi)管的蒸汽(qi)(qi)中，以(yi)降低蒸汽(qi)(qi)溫度。
2、減(jian)壓(ya)(ya)系統：由減(jian)壓(ya)(ya)閥和孔板組(zu)成。減(jian)壓(ya)(ya)閥通(tong)過改變流通(tong)面積來達(da)到調節壓(ya)(ya)力的目的。
3、降溫(wen)(wen)減(jian)(jian)壓系統：降溫(wen)(wen)系統和減(jian)(jian)壓系統合(he)二為一，減(jian)(jian)小了減(jian)(jian)溫(wen)(wen)減(jian)(jian)壓裝置的整體(ti)尺寸，增加(jia)了技術復(fu)雜度。
4、主(zhu)蒸汽管(guan)體：由混合管(guan)和蒸汽管(guan)組成。根據用戶(hu)提供的(de)參數確定，是(shi)減(jian)溫減(jian)壓裝置的(de)主(zhu)要設(she)備，目的(de)是(shi)將降溫減(jian)壓后的(de)蒸汽送入用戶(hu)所(suo)需的(de)管(guan)道(dao)中。
5、減(jian)溫(wen)減(jian)壓(ya)裝置安(an)全(quan)(quan)系統：為(wei)防止二次蒸汽(qi)壓(ya)力超過規定值，自動開啟(qi)安(an)全(quan)(quan)閥排出(chu)多(duo)余蒸汽(qi)，從而(er)達到(dao)減(jian)壓(ya)和(he)安(an)全(quan)(quan)保護(hu)的功能。
減壓系(xi)統采用雙閥座減壓閥結構，不平(ping)衡力小，調節范圍大，動作平(ping)穩，無卡阻。 減(jian)(jian)(jian)(jian)溫(wen)(wen)系(xi)統采用文丘里(li)管式噴嘴方式，無傳動部件，減(jian)(jian)(jian)(jian)溫(wen)(wen)水霧化(hua)效(xiao)果好，噴嘴拆(chai)裝方便(bian)(bian)，減(jian)(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)(jian)壓裝置維修方便(bian)(bian)。減(jian)(jian)(jian)(jian)壓系(xi)統與減(jian)(jian)(jian)(jian)溫(wen)(wen)系(xi)統分離，主(zhu)要用于惡(e)劣工(gong)況，如蒸汽流量低(di)，不適合使(shi)用減(jian)(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)(jian)壓閥，飽和蒸汽（低(di)壓）工(gong)況。減(jian)(jian)(jian)(jian)溫(wen)(wen)減(jian)(jian)(jian)(jian)壓裝置主(zhu)要采用文丘里(li)管減(jian)(jian)(jian)(jian)溫(wen)(wen)方式，減(jian)(jian)(jian)(jian)溫(wen)(wen)水充分霧化(hua)，達到更好的減(jian)(jian)(jian)(jian)溫(wen)(wen)效(xiao)果
