双金属片疏水阀说明：

　　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，推动阀心开关阀门。
　　1、双金属片式疏水阀内有调整螺栓，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%，可排不凝结气体，耐冻，体积小，能抗水锤，耐高压，任意位置都可安装。
　　2、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。

Product Overview of CS47H Bimetallic Steam Trap (English Translation)

The CS47H bimetallic steam trap is a type of thermostatic steam trap that uses a bimetallic strip as the temperature-sensing element to automatically open  close the valve, thereby discharging condensate  preventing steam leakage. This valve can automatically adjust the drainage temperature during system operation, making it suitable for various industrial steam heating systems such as power plants, oil refineries, chemical plants, paper mills, textile mills,  metallurgical facilities. Its main features include resistance to water hammer, high pressure tolerance, compact size, lightweight, freeze resistance, automatic air venting, unrestricted installation orientation, high backpressure capability (over 80%),  effective performance at high temperatures, resulting in significant energy savings.4

Key Features

New SCCV Closing System: Ensures reliable closure  long service life.

Adjustable Discharge Temperature: Maximizes the use of sensible heat  high-temperature condensate, providing notable energy savings.

Water Seal Design: Maintains high-temperature condensate before the valve, forming a reliable water seal with no steam leakage.

Flexible Installation: Can be installed at any angle to fit various pipeline layouts.

Excellent Resistance to Water Hammer  Air Venting: During startup, low-temperature condensate  air are quickly discharged, reducing equipment warm-up time.

Noiseless Operation: Operates quietly, contributing to environmental protection.

Corrosion  Erosion Resistance: All internal components are made of stainless steel, providing excellent resistance to corrosion  erosion.4
