摘要
钢厂余热回收配套的余热锅炉系统管路上安装有管路止回阀,该阀在使用中对工质管路有防止工质回流冲击、避免泵及电机反转、尽可能地减少水锤效应的影响等作用。由于钢厂余热锅炉温度很高、工况恶劣,目前常用的止回阀部分存在使用寿命短、易失效等问题。该问题已严重地影响了整个锅炉系统的运行效率和生产产出,也是余热回收需要解决的瓶颈问题之一。通过综合分析止回阀的结构特征和设计原理,采用了一种新式止回阀,该阀可靠自身重量及工质压力而动作来使工质通断,具备手动自动双用功能,同时具有截止和止回的功能,既能水平安装也能垂直安装使用。在使用性能、安全性能等方面相对于以往通用型的止回阀有很大的本质提升。
There is a pipeline stop return valve installed on the tube of the residual heat recovery of the steel plant.The valve has a preventive impact on the work quality of the working quality in the use of the working quality pipe,avoiding the reversal of the pump and motor,and the reduction of the water hammer effect as much as possible.The effect of influence.Due to the high temperature of the remaining heat boilers of the steel mill and harsh working conditions,the currently used stop valve parts have problems such as short service life and easy failure.This problem has seriously affected the operating efficiency and production and output of the entire boiler system,and it is also one of the bottleneck problems that need to be solved by residual heat recovery.It uses a comprehensive analysis of the structural characteristics and design principles of the return valve,and a new type of stopping valve is adopted.The valve reliable its own weight and work quality pressure to make the work quality.The function of the deadline and stop can be installed horizontally and vertically.Compared with the previous general-purpose stop valve in the aspects of performance,safety performance,etc.,it has greatly improved.
