双金属片式疏水阀-BK29

产品介绍:

    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)。
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。
Merits

注解
1、选型时请提供工作压力、工作压差、凝结水发生量、工作温度、连接方式及标准。
2、凝结水负荷的安全系数一般为2~3倍。
3、正确安装、定期保养清除阀内污物,保证疏水阀正常工作和延长使用寿命。
Note
1.Please provide operating pressure and operating pressure difference,generating quantity of condensate water,operating temperature,connecting mode and standards in selecting product models.
2.The load of condensate Water's safety coefficient reaches 2 to 3 times in general.
3.Please make sure the drain valve is installed properly,maintained regularly,cleaned up and operates under the normal condition,so as to extend its service life.
