style="text-indent:25px">減溫減壓裝置的作用：(1)調整汽溫，使鍋爐送出的蒸汽溫度在規(guī)定的范圍內。汽輪機對蒸汽溫度要求很嚴格，一般要求比額定汽溫正負不超過5℃，即汽溫只能允許在10℃范圍內波動。汽溫超過規(guī)定值，會使過熱器、蒸汽管道、汽輪機及閥門等設備壽命降低，嚴重時可使上述設備損壞。汽溫低于規(guī)定值，會降低機組的經(jīng)濟性。汽溫降低10℃，機組的經(jīng)濟性降低0.6%～0.8%。由于影響汽溫的因素很多，為了保持蒸汽溫度在規(guī)定范圍內，必須對蒸汽溫度進行調整。調整汽溫的方法很多，減溫減壓裝置調整汽溫是普遍采用的方法。宿州減溫減壓裝置怎么樣減溫減壓裝置其優(yōu)點是響應時間快，通過反饋系統(tǒng)對速度，位置和轉矩進行準確地控制。</p><div

style="text-indent:25px">減溫減壓裝置的流量特性：是指輸入壓力一定時，輸出壓力必須低于輸出流量g的變化而變化的特性。當流量g發(fā)生變化時，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動就越小。它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質主要是水。減溫減壓裝置普遍用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場合，以保證給水系統(tǒng)的水壓大小成正比，因此減溫減壓裝置具有改善系統(tǒng)運行工況和潛在節(jié)水作用，據(jù)統(tǒng)計其節(jié)水效果約為30%。</p><p style="text-indent:25px">減溫減壓裝置選用說明：減溫減壓裝置的應用范圍很廣，在蒸汽、壓縮空氣、工業(yè)用氣、水、油和許多其他液體介質的設備和管路上均可使用，介質流經(jīng)減溫減壓裝置出口處的量，一般用質量流量或體積流量表示；波紋管直接作用式減溫減壓裝置適用于低壓、中小口徑的蒸汽介質；薄膜直接作用式減溫減壓裝置適用于中低壓、中小口徑的空氣、水介質；先導活塞式減溫減壓裝置，適用于各種壓力、各種口徑、各種溫度的蒸汽、空氣和水介質，若用不銹耐酸鋼制造，可適用于各種腐蝕性介質；先導波紋管式減溫減壓裝置，適用于低壓、中小口徑的蒸汽、空氣等介質；減溫減壓裝置通過改變流通面積達到調節(jié)壓力的目的。</p><div

1）、采用減溫、減壓分體閥結構，使蒸汽先減壓；然后單獨減溫，分別在不同系統(tǒng)內完成，該裝置的長度提高了運行的可靠性，便于壓力、溫度的**調節(jié)。 2）、減壓系統(tǒng)：采用三種不同結構形式的減壓閥⑴采用直行程籠式減壓閥結構，多用于t≤400℃,P≤2.5MPa，介質經(jīng)多個小孔節(jié)流減壓，閥內可設多級節(jié)流降壓，增加閥體使用壽命，保護了閥座及閥體免受沖擊，延長了閥門的使用壽命，同時也降低了裝置的噪音 ⑵雙座減壓閥多用于t≤450℃,P≤4.3MPa的常規(guī)減溫減壓裝置。減溫減壓裝置是將高溫高壓蒸汽降為客戶能夠使用的低壓低溫蒸汽(可為過熱蒸汽)。池州減溫減壓裝置銷售價格</p><p style="text-indent:25px">減溫減壓裝置操作靈活，可根據(jù)不同要求任意設定參數(shù)。減壓裝置定制</p><p
