圆盘式蒸汽疏水阀 CS19H/W

圆盘式蒸汽疏水阀是根据伯努力热动力原理,利用蒸汽和凝结水的热动力学不同的特性,引起动能和势能动静压变化。使动作件阀片上下压差变化,启动阀片开启和关闭,从而达到阻汽排水目的。

圆盘式蒸汽疏水阀

1.体积小,重量轻,不受安装位置的限制。

2.全部材质均为不锈钢件,经久耐用,耐腐蚀。

3.在室外不怕冷冻,能耐水击,耐过热。

4.过冷度为 8 ℃ ,漏汽率小于实际排量 3% ,最大背压 50% 。

5.结构简单,安装维修方便。

圆盘式蒸汽疏水阀工作原理

       圆盘式蒸汽疏水阀内有一个阀片,既是敏感件又是动作执行件。当装置启动时,管道出现冷却凝结水,凝结水靠工作压力推开阀片,迅速排放。当凝结水排放完毕,蒸汽进入疏水阀内,蒸汽的体积迅速扩大,蒸汽比凝结水的流速大,使阀片上下产生压差,阀片在蒸汽流速的吸力下迅速关闭。当阀片关闭时,阀片受到两面压力,阀片下面的受力面积小于上面的受力面积,因疏水阀汽室里面的压力来源于蒸汽压力,所以阀片上面受力大于下面,阀片紧紧关闭。当疏水阀汽室里面的蒸汽降温成凝结水,汽室里面的压力消失。凝结水靠工作压力推开阀片,凝结水又继续排放,循环工作,间断排水。
