产品介绍:
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,没有新鲜蒸汽泄露(零泄露)。
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。
