style="text-indent:25px">這類疏水閥是利用蒸汽和凝結(jié)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(jié)水中的一部分顯熱，閥前始終存有高溫凝結(jié)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(shè)備，采暖設(shè)備，溫度要求不高的小型加熱設(shè)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(yīng)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(jié)氣體，膜盒堅(jiān)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(dāng)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(guān)閉方向移動，在冷凝水達(dá)到飽和溫度之前，疏水閥開始關(guān)閉。膜盒隨蒸汽溫度變化控制閥門開關(guān)，起到阻汽排水作用。分相流動模型是把氣液兩相分別作單相流處理，進(jìn)而考慮兩相間的相互作用。</p><div
