November 12, 2024
1. Impurities stuck in the sealing surface of the Plug Valve
Sometimes the Plug Valve suddenly does not close tightly. It may be that impurities are stuck between the sealing surfaces of the Plug Valve. At this time, you should not force it to close. You should open the Plug Valve a little wider and then try to close it again. Try it repeatedly. Generally, it can be eliminated. Otherwise, you should check it and keep the quality of the medium clean.
Structure of plug valve
For the Plug Valve that is usually in the open state, when it is closed accidentally, it may not close tightly because the Universal Valve has rusted. In this case, you can repeatedly open and close the Plug Valve several times, and use a small hammer to knock the bottom of the valve body at the same time, so that the Plug Valve can be closed tightly without grinding and repairing the Plug Valve.
3. The sealing surface of the Plug Valve is damaged
For the situation that it still cannot be closed tightly after trying to open and close it many times, that is, the sealing surface is damaged, and it should be repaired; or corrosion, scratches by particles in the medium, etc. have damaged the sealing surface, and it should also be repaired.
4. The Universal Valve is not connected well
Regularly add lubricating oil to the Universal Valve mother to ensure the flexible opening and closing of the Plug Valve. There should be a formal maintenance plan.
