The importance of valve maintenance and repair

Page view

[Abstract]:

At that time, most domestic industries traded new ones for old ones. At that time, the replaced valves were discarded or sold as waste products. Especially in the industry where flanged valves are commonly used. I want to repair the replaced high pressure, high temperature and large valves, but I don't know how to repair them.

Most of them are still in the manual repair stage. It can be said that in China's valve repair industry, the waste and the available benefits are huge. A power station (4x5omw ~ 4x2oomw) needs to repair tens of thousands of steam turbine valves and bypass valves every year.

The power plant has only one grinding machine imported from Germany in 1992, and the others are manually operated. Not only is the efficiency inefficient, but also the accuracy does not meet the requirements. The bypass high-pressure relief valve leaked, but the power plant could not repair it. The effect of sending to Shanghai for repair is not satisfactory.

In recent years, as various units have gradually started independent economic accounting to reduce costs, from management personnel to front-line maintenance workers have gradually realized the importance of repairing valves, because the money saved in this respect is extremely considerable.
