DISC （THERMO-DYNAMIC） TRAP

圆盘式热动力型疏水阀

　　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.
