进口双金属片式疏水阀原理特点
进口双金属片式疏水阀是一种由双金属片感温元件组成的阀门，它随蒸汽温度升降受热变形，推动阀心开关阀门。双金属片式疏水阀设有调整螺栓，可根据需要调节使用温度，一般过冷度调整范围低于饱和温度15℃-30℃，背压率大于70%，能排不凝结气体，不怕冻，体积小，能抗水锤，耐高压，任意位置都可安装。
BM140 Series bimetallic steam traps and air eliminators are simple and robust traps, recommended for steam where condensate sensible heat can be recovered, steam tracing lines, drip points, storage tank coils, steam air venting, etc. The use of condensate sensible heat reduces the steam consumption.
Connections are female screwed, socket weld, butt weld or flanged.
