双金属片式疏水阀

双金属片式疏水阀

　　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。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）。

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：
