Maintenance methods for manual flange gate valves

The maintenance methods for manual flange gate valves include the following aspects:

      1. Regular inspection: Regularly check the appearance of the manual gate valve to observe whether there are any problems such as leakage, abnormal wear or corrosion. At the same time, check whether the connection between the valve body and the valve stem is normal and whether there is any looseness.

       2. Clean the valve: Clean the manual gate valve regularly. You can use a brush or compressed air to remove dirt and debris on the surface of the valve. Especially the valve sealing surface and valve seat, make sure they are clean and free of impurities.

       3. Lubrication maintenance: The moving parts of the manual gate valve need to be lubricated and maintained. Add an appropriate amount of grease or lubricating oil to the required position to ensure the flexible movement of the valve.

       4. Sealing maintenance: Regularly check the sealing performance of the manual gate valve, especially the sealing between the valve seat and the valve sealing surface. If water leakage or poor sealing is found, the seal needs to be repaired or replaced in time.

       5. Operation and maintenance: Operate the manual gate valve correctly to avoid damage caused by excessive force or improper operation. At the same time, operate the valve regularly, open and close the valve several times to ensure the flexibility and sealing of the valve.

       6. Anti-corrosion maintenance: If the manual gate valve is used in a humid or corrosive environment, anti-corrosion maintenance is required. Anti-corrosion coatings, anti-corrosion oils and other materials can be used to treat the surface of the valve to extend the service life of the valve.

      In short, the maintenance method of the manual gate valve is mainly regular inspection, cleaning, lubrication, sealing, operation and anti-corrosion maintenance. If a problem is found in the valve, it is necessary to repair or replace the parts in time to ensure the normal operation and service life of the valve.
