可调双金属片式疏水阀-TB11
我们坚持以客户需求为导向，以技术创新为动力，为您提供从产品选型到技术咨询的全方位服务，助力企业提升蒸汽系统能效，创造更大价值。
详情介绍
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、排放温度可在线调整，安装姿势自由。
2、利用高温凝结水形成水封，有效减少蒸汽泄露。
3、动作灵敏，抗水击，无噪声，排空性能优良。
4、结构简单，容易维修保养。
5、用于蒸汽主管、分汽缸、蒸汽伴热管线、散热器、低温加热槽、夹层锅等。
6、可以使用高压高温的蒸汽管线、分汽缸。
