<p> 3、方位空間及原系統(tǒng)流程圖。 </p> <p> </p> <p> <p> 三、工作原理 </p> <p> 汽液兩相流自調節(jié)液位控制器是基于流體力學理論和控制原理，利用汽液兩相流的流動特性設計的一種全新概念的液位控制器，屬自力式智能調節(jié)，需消耗少量的汽（約為排水量的1-2%）作為執(zhí)行機構的驅動源。該控制器連接系統(tǒng)如圖所示。調節(jié)器的作用是控制出口水量，相當于自動調節(jié)系統(tǒng)中的執(zhí)行機構。其調節(jié)原理是：當加熱器的水位升高時，信號管內(nèi)的水位隨之上升，導致發(fā)送的調節(jié)汽量減少，因而流過調節(jié)器中兩相流的汽量減少、水量增加，加熱器的水位隨之下降。反之亦然。由此實現(xiàn)了加熱器水位的自動控制。 </p> </p><p style="text-indent:25px">這類疏水閥是利用蒸汽和凝結水的溫差引起感溫元件的變型或膨脹帶動閥心啟閉閥門。熱靜力型疏水閥的過冷度比較大，一般過冷度為15度到40度，它能利用凝結水中的一部分顯熱，閥前始終存有高溫凝結水，無蒸汽泄漏，節(jié)能效果明顯。是在蒸汽管道，伴熱管線、小型加熱設備，采暖設備，溫度要求不高的小型加熱設備上，比較理想的疏水閥。熱靜力型疏水閥有膜盒式、波紋管式、雙金屬片式, 膜盒式疏水閥的主要動作元件是金屬膜盒，內(nèi)充一種氣化溫度比水的飽和溫度低的液體,有開閥溫度低于飽和溫度15℃和30℃兩種供選擇。膜盒式疏水閥的反應特別靈敏，不怕凍，體積小，耐過熱，任意位置都可安裝。背壓率大于80%，能排不凝結氣體，膜盒堅固，使用壽命長，維修方便，使用范圍很廣。裝置剛起動時，管道出現(xiàn)低溫冷凝水，膜盒內(nèi)的液體處于冷凝狀態(tài)，閥門處于開啟位置。當冷凝水溫度漸漸升高，膜合內(nèi)充液開始蒸發(fā)，膜合內(nèi)壓力上升，膜片帶動閥心向關閉方向移動，在冷凝水達到飽和溫度之前，疏水閥開始關閉。膜盒隨蒸汽溫度變化控制閥門開關，起到阻汽排水作用。自高加疏水進行汽液兩相流自調裝置改造以來，取消了電動調節(jié)閥，靠安裝在零米的自調裝置就能滿足疏水要求。</p><div

style="text-indent:25px">杠桿浮球式疏水閥基本特點與自由浮球式相同，內(nèi)部結構是浮球連接杠桿帶動閥心，隨凝結水的液位升降進行開關閥門。杠桿浮球式疏水閥利用雙閥座增加凝結水排量，可達到體積小排量大，比較大疏水量達100噸/小時，是大型加熱設備理想的疏水閥。倒吊桶式疏水閥內(nèi)部是一個倒吊桶為液位敏感件，吊桶開口向下，倒吊桶連接杠桿帶動閥心開閉閥門。倒吊桶式疏水閥能排空氣，不怕水擊，抗污性能好。過冷度小，漏汽率小于3%，比較大背壓率為75%，連接件比較多，靈敏度不如自由浮球式疏水閥。因倒吊桶式疏水閥是靠蒸汽向上浮力關閉閥門，工作壓差小于0.1MPA時，不適合選用。當裝置剛啟動時，管道內(nèi)的空氣和低溫凝結水進入疏水閥內(nèi)，倒吊桶靠自身重量下墜，倒吊桶連接杠桿帶動閥心開啟閥門，空氣和低溫凝結水迅速排出。當蒸汽進入倒吊桶內(nèi)，倒吊桶的蒸汽產(chǎn)生向上浮力，倒吊桶上升連接杠桿帶動閥心關閉閥門。倒吊桶上開有一小孔，當一部份蒸汽從小孔排出，另一部份蒸汽產(chǎn)生凝結水，倒吊桶失去浮力，靠自身重量向下沉，倒吊桶連接杠桿帶動閥心開啟閥門，循環(huán)工作，間斷排水。本設備可用于鍋爐的汽包、汽機的高、低加熱器。蒸發(fā)器、熱交換器、連續(xù)排污擴容器等諸多設備配套使用。連云港哪里有銷售汽液兩相流水位自動控制裝置廠家</p><p

style="text-indent:25px">運行實踐表明，汽液兩相流水位自動控制裝置投運后自調節(jié)能力強，當機組負荷在60％～100％范圍內(nèi)變化時，加熱器水位波動值為50～100mm，并能全自動工作，保證水位上不報警，下有水位。而且，調試操作簡單方便，一次調整到位后再不需進一步調整，可做到不用操作隨機啟停，減輕了運行人員的維護管理工作量。由于汽液兩相流水位自動控制裝置同原水位調節(jié)器相比，無機械運行部件和電氣、氣動控制元件，因此水位調節(jié)器的故障率大幅度降低，減輕了現(xiàn)場檢修人員的維護工作量，使用壽命長。由于新型水位調節(jié)器是全密封裝置，因此無泄漏且安全可靠。原有水位調節(jié)器的熱工控制系統(tǒng)和裝置全部取消，免除了熱工人員的維護管理。某電廠200MW機組6＃機改造前給水溫度（2002年下半年平均值）為234.4℃，改造后給水溫度（2003年下半年平均值）為239.6℃，給水溫度上升5.2℃。根據(jù)200MW機組熱力計算結果；給水溫度每升高10℃，影響煤耗2.0g／kw·h。若扣除負荷因素，下半年發(fā)電量4.5億kw·h，則下半年節(jié)約標準煤450t，全年按9.0億kw·h發(fā)電量計算，則全年節(jié)約標準煤900t。改造后經(jīng)濟效益十分明顯。連云港生產(chǎn)給水兩相流多少錢</p><p
