The defect analysis of China gate valve: the structure is more complex and the maintenance is inconvenient

China gate 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 of fluid control field. However, Chinese gate valves also have some shortcomings, such as complex structure and inconvenient maintenance. This article will analyze the shortcomings of Chinese gate valves from a professional perspective for you.

1. The structure is complex

Compared with other types of valves, the structure of Chinese gate valves is more complex. Chinese gate valves are usually composed of body, gate, stem and seals, each of which requires precision machining and fitting. This makes the Chinese gate valve in the design and manufacturing process requires a higher level of technology and cost input.

2. Maintenance is inconvenient

Because the structure of Chinese gate valves is more complex, more care and care are needed in the maintenance process. If the Chinese gate valve fails or needs to be replaced, it needs to be disassembled and replaced, which requires professional technical personnel to operate. At the same time, because the structure of China’s gate valve is more complex, it is also prone to damage or misoperation during disassembly and replacement.

3. Limited scope of application

Although the Chinese gate valve is suitable for the control of low and medium pressure fluids, its scope of application is relatively limited. Due to the complex structure of gate valves in China, the application of gate valves in harsh environments such as high pressure, high temperature and corrosion is limited to some extent. In addition, the sealing surface of Chinese gate valves is vulnerable to wear and corrosion, so more attention needs to be paid to maintenance and maintenance during use.

In short, although the Chinese gate valve has the advantages of simple structure and good sealing, its complex structure and inconvenient maintenance also need to be paid attention to. In practical applications, the appropriate valve type should be selected according to the specific situation, and pay attention to maintenance to extend the service life and performance of the valve. I hope the defect analysis of Chinese gate valve in this article can provide you with some reference and help.
