產(chǎn)品介紹：
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).
優(yōu)點(diǎn)：
1、結(jié)構(gòu)簡單，容易安裝和維修，抗水擊，排空性能*。
2、利用高溫凝結(jié)水形成水封，沒有新鮮蒸汽泄露（零泄露）。
3、動(dòng)作靈敏，無噪聲。
4、抗水擊，對(duì)壓力突然變化沒有影響。
5、可用于過熱蒸汽系統(tǒng)。
6、可以使用高壓高溫的蒸汽管線。
7、具有良好的排空氣性能，不怕凍。
