rr TD42热动力圆盘式蒸汽疏水阀特点r
rr 体积小,重量轻,不受安装位置的限制。
r全部材质均为不锈钢件,经久耐用,耐腐蚀。
r在室外不怕冷冻,能耐水击,耐过热。
r过冷度为8℃,漏汽率小于实际排量3%,最大背压50%。
r结构简单,安装维修方便。r
r 工作原理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。
