Application of New Type Check Valve in Waste Heat Boiler of Steelmaking
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 princi-ples 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.
