Maintenance method of flange ball valve

Flange ball valve maintenance method
Flange ball valve classification is stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Flanged ball valves are very easy to contact with other metal and iron products during the manufacturing process. Regarding the situation that the flanged ball valve has not rusted, then everyone knows what maintenance work needs to be done for the flanged ball valve?

The maintenance method of flange ball valve is as follows:
1. After the finished product, after pickling, it must be rinsed. If there are sand holes or perforations, it should be gas shielded welding by argon arc welding. Then it is polished, and then solid-solution treatment is carried out;
2. The finished product, after the pressure test is completed. It should be rinsed with water added with anti-rust powder.
3. After installing the pipeline, regularly maintain and maintain it. For example, the valve stem is often lubricated. Properly open and close the valve several times. It is not easy to assimilate the inner ball, valve stem and sealing surface.
4. Use wooden boxes as much as possible during transportation, and do not touch metal products.
When we all operate and use flanged ball valves, flanged ball valves generally have two structures: reduced diameter and non-reduced diameter channels. Regardless of the structure, the flow resistance coefficient of the ball valve is relatively small. Because the diameter of the channel is equal to the inner diameter of the pipe, the local resistance loss is only the frictional resistance of the pipe of the same length, and the flow resistance Z of this ball valve is small.
When we all operate and use flanged ball valves, we all need to maintain them in accordance with the above maintenance methods. The correct way to maintain flanged ball valves is what we all need.
