Description:

双金属片式疏水阀SF-123/SF-123-GF

双金属片式疏水阀用于蒸汽管网及设备中,能自动排出凝结水、空气及其它不凝结气体,并防止水蒸汽泄漏。疏水阀基本的工作原理就是利用蒸汽和水的重量差和温度差来实现疏水的目的。

【 排量图 】

【 通用型双金属疏水阀的四种功能 】

1、起止回阀作用:阀球能在管线产生回流时,立即关闭排放孔,无须附加装置。 2、排放冷凝水:冷凝水逐步渐降低了双金属元件的热拉力,使排放孔逐渐打开,冷凝水畅通无阻碍地排放。 3、阻汽:进入阀腔中的蒸汽使双金属元件弯曲产生热拉力,并克服管道压力是关闭阀球。热拉力是随相应的饱和蒸汽曲线变化的。因此,在其压力范围内都能有效地工作。 4、排空气和水:输送管线的压力或重力使阀打开,迅速排除空气和水,缩短升温时间。
