进口双金属片式疏水阀

BIMETALLIC TRAP

德国莱克（LIK）进口双金属片式疏水阀的热敏元件为两种不同膨胀率的金属通过特殊工艺压铸一起的双金属片，双层金属片在受热后膨胀，由于不同的膨胀率使其产生的弯曲。利用这种特性制作成疏水阀的热敏元件起到开关作用。双金属片式疏水阀分为不可在线调节（BK，CS17H和CS47）和可在线调节（可调双金属片式TB）。

 

Bimetallic Trap

The thermo-sensitive element of bimetallic trap is a bimetallic element cast through a special process by two metals of different expansion ratio. When the bimetallic element expands after heated, different expansion ratio results in bending. The thermo-sensitive element produced on the basis of this quality can act as a switch. Bimetallic traps are divided into adjustable offline （BK，CS17H and CS47） and online （adjustable bimetallic element TB）.

 

优点：

1、结构简单，容易安装和维修，抗水击，排空性能优越。

2、利用高温凝结水形成水封，没有新鲜蒸汽泄漏（零泄漏）。

3、动作灵敏，无噪声。

4、抗水击，对压力突然变化没有影响。

5、可用于过热蒸汽系统。

6、可以使用高压高温的蒸汽管线。

7、具有良好的排空气性能，不怕冻。
