膜盒式蒸汽疏水阀 CS46H

热静力型膜盒式蒸汽疏水阀(蒸汽压力平衡式)是目前国际上最常用的先进节能型疏水阀膜盒式蒸汽疏水阀的反应非常灵敏,工作时阀前存有高温凝结水,无蒸汽泄漏,节能效果显著。
膜盒式蒸汽疏水阀的优点是:自动排空气,体积小,不怕冻,任意位置都可安装;维护方便,在管线上可以检查修理和更换零件;最大背压率 ≤80% ,膜盒坚固,使用寿命长。 
     
膜盒式蒸汽疏水阀适用于蒸汽主管线、蒸汽伴热管网、仪表伴热和小型加热设备的阻汽排水,使用范围很广。

工作原理

      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。有开阀温度低于饱和温度 15 ℃ 和 30 ℃ 两种膜盒供选择。
