產品名稱：圓盤式（熱動力）疏水閥

圓盤式（熱動力）疏水閥  DISC (THERMO-DYNAMIC) TRAP    　　圓盤式疏水閥 　　裝置剛啟動時，首先在較低的壓力下空氣和冷凝水流過疏水閥，通過入口孔托起閥片，再由出口孔排出，當壓力、溫度上升后，內壓上升，推動凝結水量增多，而增大流速，這時閥片下的靜壓降低，使閥片下落，蒸汽從出口孔中間由四周流向閥片和閥蓋之間的間隙，進入壓力室，將閥片壓在密封環上，關閉閥門。當壓力室的蒸汽溫度降低，開始冷凝，使壓力室內的壓力降低，進口壓力托起閥片，疏水閥開啟進行排水。   Disc Trap When starting the device, firstly, the air and condensed water will flow across steam trap under rather low pressure, and lift valve plate through the entrance hole, and then discharge from the exit hole. After the pressure and temperature rise, the inner pressure will also rise, and cause increased amount of condensed water and increased flow rate, at the moment, the static pressure of valve plate declines which causes the drop of valve plate, and then, the steam flows from all directions via the exit hole into the gap between the valve plate and the valve cover. After steam enters the pressure chamber, it shuts down the valve by pressing valve plate onto the sealing ring. When the steam temperature inside the pressure chamber begins descending and the steam begins to congeal, the pressure declines in the pressure chamber, and the inlet pressure lifts the valve plate, and then the steam trap opens and discharges water.   優點： 1、結構簡單，容易安裝和維修，抗水擊。 2、抗水擊，對壓力突然變化沒有影響。 3、可用于過熱蒸汽系統。 4、可以使用高壓高溫的蒸汽管線。   Merits 1.Simple structure, easy installation and maintenance and water hammer resistant. 2.Water hammer resistant and no effect from abrupt change of pressure. 3.Adoptable for overheat steam system. 4.Adoptable for high-pressure and high-temperature steam pipes.   技術參數/Technique parameter 殼體壓力等級 Shell pressure grade 負荷泄漏率 Load leakage rate 使用介質 Used medium 殼體材質 Shell material 允許背壓率 Permitted backpressure rate 1.6～42MPA 0.3% 蒸汽、凝結水 Steam、Condensate water 鍛鋼、不銹鋼、合金鋼 Forged steel、Stainless steel、Alloy steel 50%   工作壓差 Maximum operating pressure differential 使用過熱蒸汽 Use superheated steam 允許溫度 Maximum allowable temperature 抗水擊 Resist 壓力變化范圍 Pressure change range 17MPA Excellence 420~550℃ 適應 Adaption 適應 Adaption   主要零件材料/The materials of primary accessories 零部件名稱Part and component name 材質Material 閥體、閥蓋Valve body、Valve cover 鍛鋼、不銹鋼、合金鋼Forged steel、Stainless steel、Alloy steel 閥片Valve plate 高鉻不銹鋼High chrome stainless steel 閥座Valve seat STL合金STL alloy 過濾網Filtrating screen 不銹鋼Stainless steel
