五、进口膜盒式疏水阀工作原理：

热静力型膜盒式蒸汽疏水阀的主要动作元件是金属膜盒，内充一种气化温度比水的饱和温度低的液体。装置刚起动时，管道出现低温冷凝水，膜盒内的液体处于冷凝状态，阀门处于开启位置。当冷凝水温度渐渐升高，膜盒内充液开始蒸发，膜盒内压力上升，膜片带动阀心向关闭方向移动，在冷凝水达到饱和温度之前，疏水阀完全关闭，膜盒随蒸汽温度变化控制阀门开关，起到阻汽排水作用。有开温度低于饱和温度 15 ℃ 和 30 ℃ 两种膜盒供选择。

The main action element of the steam trap is metal diaphragm, which is filled with a liquid whose gasification temperature is lower than the saturation temperature of water. When the device is just started, there is low-temperature condensate in the pipeline, the liquid in the capsule is in the state of condensation, and the valve is in the open position. When the temperature of condensate gradually increases, the liquid filled in the capsule starts to evaporate, the pressure in the capsule rises, and the diaphragm drives the valve center to move towards the closing direction. Before the condensate reaches the saturation temperature, the drain valve is completely closed, and the capsule controls the valve switch with the change of steam temperature, which plays the role of steam blocking and water drainage. There are two kinds of bellows with opening temperature 15 ℃ and 30 ℃ lower than saturation temperature.
