双金属片式疏水阀介绍 双金属片疏水阀的主要部件是双金属片感温元件，随蒸汽温度升降受热变形，推动阀芯开关阀门。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，能抗水击，耐高压，任意位置都可安装。双金属片有疲劳性，需要经常调整。 当装置刚启动时，管道出现低温冷凝水，双金属片是平展的，阀芯在弹簧的弹力下，阀门处于开启位置。当冷凝水温度渐渐升高，双金属片感温起元件开始弯曲变形，并把阀芯推向关闭位置。在冷凝水达到饱和温度之前，疏水阀开始关闭。双金属片随蒸汽温度变化控制阀门开关，阻汽排水。

Bimetal traps introduced The main components of the bimetal traps bimetal temperature sensing element and thermal deformation, to promote the spool off valves with steam temperature lift. Bimetal steam trap with the adjusting bolt, according to the need to regulate the use of temperature, generally cooling degree adjustment range is lower than the saturation temperature of 15 ℃ -30 ℃, the back pressure greater than 70% can be ranked, non-condensing gas, and not afraid of cold. , small size, resistant to water hammer, high pressure, any location can be installed. The bimetal fatigue need to be adjusted regularly. When the device has just started, the pipeline appears that the low-temperature condensate, the bimetallic strip is flattened, in the spring will, the spool valve in the open position. When the condensation water temperature gradually increased, bimetal temperature from the component bending deformation, and the spool to the closed position. Before the saturation temperature in the condensate, the trap began to close. With the steam temperature, the bimetal control valve switch, resistance of air drainage.
