进口螺纹疏水阀工作原理:

进口内螺纹疏水阀工作原理：1、当设备刚启动时，管道内出现空气和冷凝水，此时浮球在双金属片的支撑下远离阀,阀口打开，空气和冷凝水迅速排出，实现快速启动。2、热凝水进入疏水阀，阀内温度迅速上升，温度到达饱和温度之前，双金属片感温变形伸直。3、当凝结水停止进入疏水阀时，浮球随液位下降关闭阀口，由于阀座总是在凝结水液位以下，形成水封，无蒸汽泄漏。4、当热凝水再次进入疏水阀时，浮球随凝结水液位自动调节阀口大小。

Working principle of inlet thread drain valve:
Working principle of inlet internal thread drain valve: 1. When the equipment is just started, air and condensate appear in the pipeline. At this time, the floating ball is far away from the valve under the support of bimetallic sheet, the valve port is opened, and the air and condensate are discharged quickly, so as to realize rapid start. 2. When the condensate enters the drain valve, the temperature in the valve rises rapidly. Before the temperature reaches the saturation temperature, the bimetallic sheet is deformed and straightened. 3. When the condensate stops entering the drain valve, the floating ball will close the valve port as the liquid level drops. Since the valve seat is always below the condensate liquid level, a water seal will be formed, and there is no steam leakage. 4. When the hot condensate enters the drain valve again, the floating ball will automatically adjust the size of the valve port with the condensate level.
