BK28疏水閥、BK29疏水閥、BK212疏水閥

德國gestra疏水閥

  雙金屬片式疏水閥的熱敏元件為兩種不同膨脹率的金屬通過特殊工藝壓鑄一起的雙金屬片，雙層金屬片在受熱后膨脹，由于不同的膨脹率使其產(chǎn)生的彎曲。利用這種特性制作成疏水閥的熱敏元件起到開關(guān)作用。雙金屬片式疏水閥分為不可在線調(diào)節(jié)（BK，CS17H和CS47）和可在線調(diào)節(jié)（可調(diào)雙金屬片式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). 
優(yōu)點：
1、結(jié)構(gòu)簡單，容易安裝和維修，抗水擊，排空性能優(yōu)越。
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、動作靈敏，無噪聲。
4、抗水擊，對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。
