    熱靜力式(膜盒)疏水閥
    THERMO-STATIC (BELLOWS) TRAP
     
      膜盒式疏水閥
      膜盒式蒸汽疏水閥的主要動作元件是金屬膜盒,內充一種氣化溫度比水的飽和溫度低的液體。裝置剛啟動時,管道出現低溫冷凝水,膜盒內的液體處于冷凝狀態,閥門處于開啟位置。當冷凝水溫度漸漸升高,膜盒內充液開始蒸發,膜盒內壓力上升,膜片帶動閥芯向關閉方向移動,在冷凝水達到飽和溫度之前,疏水閥完全關閉。膜盒隨蒸汽溫度變化控制閥門開關,起到阻汽排水作用。有開閥溫度低于飽和溫度15℃和30℃兩種膜盒供選擇。
      膜盒式蒸汽疏水閥(蒸汽壓力平衡式)是節能型疏水閥。膜盒式蒸汽疏水閥的反應非常靈敏,工作時閥前存有高溫凝結水,無蒸汽泄漏,節能效果顯著。
      膜盒式在蒸汽管線中是代替低壓(壓力在PN25以下)熱動力(圓盤式)疏水閥或(壓力在PN16以下)雙金屬片式疏水閥的理想替代品。
     
    Bellows Trap
    The main acting unit of bellows trap is metal bellows, which is filled with a type of liquid with gasification temperature lower than water’s saturation temperature. When the device just starts, there appears condensate with low temperature in conduits and the liquid in the bellows is in the condensed state. The trap is turned on. When the temperature of condensate water gradually goes up, the liquid in the bellows begins to vaporize and the pressure within it increases. Consequently, the film drives the valve core to move towards the closing direction. Before the condensate water reaches its saturation temperature, the trap is completely shut down. The bellows controls the opening and closing of valves in accordance with steam temperature changes so as to resist steam and discharge water. Available are two alternative bellows with opening temperature 15℃ or 30℃ lower than saturation temperature.
    Bellows trap (with balanced steam pressure) is energy-saving traps . As they are sensitive with high-temperature condensate deposits in front of valves while operating, they boast of remarkable energy-saving effect with no steam leakage.
    Bellows trap, among all existing steam pipes, are presently the ideal substitute of low-pressure (with pressure below PN25) hot motive (disc) traps or bimetallic elements traps (with pressure below PN16).
