China ball valve defect analysis: maintenance is more complex

Ball valve is a commonly used fluid control equipment, its simple structure, good sealing and other advantages make it widely used in petroleum, chemical, metallurgy, electric power and other industries in the field of fluid control. However, compared with the advantages, China ball valve also has some disadvantages, one of which is more complex maintenance. This article will be from a professional point of view, for you to analyze the shortcomings of China ball valve.

1. Maintenance is more complicated

Compared with other types of valves, the maintenance of Chinese ball valves is more complex. Because the structure of China ball valve is relatively simple, it has fewer parts and is relatively easy to maintain. However, China ball valve has more moving parts, such as bearings, gears, etc. These parts need regular lubrication and maintenance, otherwise it will affect the service life and performance of the valve. In addition, the seals of Chinese ball valves also need to be replaced regularly to ensure the sealing performance of the valves.

2. Not suitable for high temperature and high pressure environment

The structure of China ball valve is relatively simple, so it is easy to deformation and jam in high temperature and high pressure environment. If you need to use Chinese ball valves in high temperature and high pressure environments, special design and manufacturing are required, which increases the cost and difficulty.

3. Can not withstand radial force

The structural characteristics of China ball valve determine that it cannot withstand too much radial force. If excessive radial force is applied during installation or use, the ball will be deformed or damaged, which will affect the service life and performance of the valve. Therefore, in the installation and use of China ball valve, it is necessary to pay attention to avoid excessive radial force.

In short, although the Chinese ball valve has the advantages of simple structure and good sealing, its maintenance is more complex, not suitable for high temperature and high pressure environments, and can not withstand radial forces and other shortcomings also need attention. In the selection and use of China ball valve, the appropriate model and specification should be selected according to the actual needs, and appropriate measures should be taken to reduce the difficulty of maintenance and use.
