热静力型疏水阀：
这类疏水阀是利用蒸汽和凝结水的温差引起感温元件的变型或膨胀带动阀心启闭阀门。热静力型疏水阀的过冷度比较大，一般过冷度为15度到40度，它能利用凝结水中的一部分显热，阀前始终存有高温凝结水，无蒸汽泄漏，节能效果显著。是在蒸汽管道，伴热管线、小型加热设备，采暖设备，温度要求不高的小型加热设备上，***理想的疏水阀。
热静力型疏水阀有膜盒式、波纹管式、双金属片式
1.膜盒式式疏水阀：
膜盒式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,有开阀温度低于饱和温度15℃和30℃两种供选择。膜盒式疏水阀的反应特别灵敏，不怕冻，体积小，耐过热，任意位置都可安装。背压率大于80%，能排不凝结气体，膜盒坚固，使用寿命长，维修方便，使用范围很广。
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，膜合内充液开始蒸发，膜合内压力上升，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，疏水阀开始关闭。膜盒随蒸汽温度变化控制阀门开关，起到阻汽排水作用。
