Maintaining Butterfly Valves is an important measure to ensure their normal operation and extend their service life. Here are some key maintenance steps:

Regular inspection: Check the appearance of the valve regularly, including the valve body, valve cover, bolts and other parts, to ensure that there is no damage, no rust, no loosening. At the same time, check the sealing performance of the valve, observe whether there is gas leakage, leakage or oil leakage, and find and solve the problem in time.

Cleaning and maintenance: Regularly clean the valve surface and internal components, remove dust, oil and sediment, and keep the valve clean and unobstructed. For removable parts, such as spool, seat, etc., should be regularly removed and cleaned to remove internal dirt and sediment.

Lubrication maintenance: For parts that need lubrication, such as valve stem, journal and other transmission parts, lubrication maintenance should be carried out regularly. The use of appropriate lubricants can reduce friction and wear and maintain the flexibility and tightness of the valve.

Replacement of wearing parts: Seals, O-rings and other components of Butterfly Valves are vulnerable parts and should be inspected and replaced regularly. If the seals are found to be aging, worn or damaged, new seals should be replaced in time to ensure the sealing performance of the valve.

Anti-corrosion treatment: For corrosion-prone parts, such as valve bodies, valve covers, etc., anti-corrosion measures such as coating anti-corrosion paint can be taken to extend the service life of the valve.

Safety precautions: When maintaining and maintaining the closed valve, ensure that the equipment has been powered off or the relevant air and liquid sources have been closed to prevent accidents. At the same time, maintenance personnel should wear personal protective equipment to ensure personal safety.

Through the above maintenance measures, the normal operation and service life of Butterfly Valves can be ensured, providing a reliable guarantee for industrial production.
