产品名称：圆盘式（热动力）疏水阀

圆盘式（热动力）疏水阀  DISC (THERMO-DYNAMIC) TRAP    　　圆盘式疏水阀 　　装置刚启动时，首先在较低的压力下空气和冷凝水流过疏水阀，通过入口孔托起阀片，再由出口孔排出，当压力、温度上升后，内压上升，推动凝结水量增多，而增大流速，这时阀片下的静压降低，使阀片下落，蒸汽从出口孔中间由四周流向阀片和阀盖之间的间隙，进入压力室，将阀片压在密封环上，关闭阀门。当压力室的蒸汽温度降低，开始冷凝，使压力室内的压力降低，进口压力托起阀片，疏水阀开启进行排水。   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.   优点： 1、结构简单，容易安装和维修，抗水击。 2、抗水击，对压力突然变化没有影响。 3、可用于过热蒸汽系统。 4、可以使用高压高温的蒸汽管线。   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.   技术参数/Technique parameter 壳体压力等级 Shell pressure grade 负荷泄漏率 Load leakage rate 使用介质 Used medium 壳体材质 Shell material 允许背压率 Permitted backpressure rate 1.6～42MPA 0.3% 蒸汽、凝结水 Steam、Condensate water 锻钢、不锈钢、合金钢 Forged steel、Stainless steel、Alloy steel 50%   工作压差 Maximum operating pressure differential 使用过热蒸汽 Use superheated steam 允许温度 Maximum allowable temperature 抗水击 Resist 压力变化范围 Pressure change range 17MPA Excellence 420~550℃ 适应 Adaption 适应 Adaption   主要零件材料/The materials of primary accessories 零部件名称Part and component name 材质Material 阀体、阀盖Valve body、Valve cover 锻钢、不锈钢、合金钢Forged steel、Stainless steel、Alloy steel 阀片Valve plate 高铬不锈钢High chrome stainless steel 阀座Valve seat STL合金STL alloy 过滤网Filtrating screen 不锈钢Stainless steel
