How to maintain ball valves? 
As a common pipeline valve, ball valves are widely used in industries such as petroleum, chemical, power, metallurgy, and pharmaceuticals. Regular maintenance is essential to ensure the normal operation of ball valves and extend their service life. The following will introduce the maintenance methods of ball valves to help users maintain them correctly and ensure their normal use.
1. Pay attention to the appearance of ball valves
Firstly, it is necessary to observe the appearance of the ball valve in a timely manner. Check the ball valve for any abnormal conditions such as leakage, deformation, or abnormal noise, as well as for any loose, corroded, or worn components. If any problems are found, they should be repaired or replaced in a timely manner.
2. Check the sealing performance of the ball valve
The sealing performance of ball valves plays an important role in their normal operation. Regularly inspect the sealing surface of the ball valve. If any wear, corrosion or other issues are found, they should be repaired or replaced in a timely manner.
3. Clean the inside of the ball valve
After working for a period of time, there may be residue accumulation inside the ball valve. Regularly clean the inside of the ball valve by using specialized cleaning solution or clean solvent to ensure smooth operation.
4. Adding lubricants
When the ball valve is running, it is necessary to maintain good lubrication. Regular addition of lubricants can reduce friction during ball valve operation and extend the service life of the ball valve. The type and method of adding lubricant should be determined based on the specific model and requirements of the ball valve.
5. Regular maintenance of spring load
The spring load in the ball valve may change after prolonged use, affecting the normal operation of the ball valve. Regular maintenance of the spring load to ensure it is within the specified range can improve the stability and reliability of the ball valve.
6. Regularly verify the performance of ball valves
To ensure that the performance of the ball valve meets the requirements, regular calibration of the ball valve is necessary. A comprehensive performance test can be conducted on the ball valve through laboratory testing equipment, such as sealing performance, pressure capacity, etc., to ensure the normal operation of the ball valve.
7. Corrosion resistant treatment
Ball valves are commonly used in pipelines with corrosive media, so they are often exposed to corrosive environments. In order to enhance the corrosion resistance of ball valves, anti-corrosion treatment can be applied to the surface of the ball valve, such as coating with special coatings or using corrosion-resistant materials to manufacture the ball valve.
In short, regular maintenance is crucial for the normal operation of ball valves. By using the above maintenance methods, the service life of ball valves can be extended, the probability of failures can be reduced, the reliability and safety of ball valves can be improved, and the normal operation of pipeline systems can be ensured.
