双金属片式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。双金属片有疲劳性，须要经常调整。 当装置刚起动时，管道出现低温冷凝水，双金属片是平展的，阀心在弹簧的弹力下，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，并把阀心推向关闭位置。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。

原文：
Bimetallic steam trap of the main components is a two-metal temperature sensing element, with the steam heat distortion temperature of movements to promote heart valves switch valves. Bimetallic steam trap has to adjust bolts needed to be adjusted according to temperature, the general cooling-degree adjustment range below the saturation temperature of 15 ℃ -30 ℃, the rate of more than 70% back pressure can be ranked non-condensing gas, are not afraid of cold , small size, resistant to water hammer, high pressure, can be installed anywhere. There are pairs of metal fatigue and requires frequent adjustment. When the device just starting when the low-temperature condensed water pipe occurs, double metal film is flat, and the elastic spring heart valve, the valve in the open position. When the condensate water temperature gradually increased, from bimetal temperature sensing element began to bend, and to heart valve into the closed position. In the condensate to saturation temperature before the trap began to close. Pairs of metal sheets with the steam temperature control valve switch, blocking drainage steam.
