Common faults and solutions
leak
Reasons: Wear or damage to the sealing surface, aging or deformation of the sealing gasket, loose connections, etc.
Solution: Check and replace the sealing surface or gasket, and tighten all loose connection parts.
freeze
Reason: The deposition of impurities in the medium leads to increased friction between the gate and valve seat, rust or bending of the valve stem, and tight fit between the gate and valve seat.
Solution: Clean the dirt inside the valve, repair or replace the valve stem, and adjust the tightness between the gate and the valve seat appropriately.
Cannot open or close
Reason: The gate has lost its clamping, the connection between the valve stem and thread is loose, and the valve resistance is too high.
Solution: Adjust the position of the gate again to ensure it is tightened, tighten the connection between the valve stem and thread, and consider reducing the operating resistance of the valve.
loud noise
Reason: There is air or fluid oscillation between the valve and the valve seat, excessive friction between the valve and the pipeline, uneven sealing surface, etc.
Solution: Eliminate air or fluid oscillation phenomena, optimize the contact between valves and pipelines, and replace uneven sealing surfaces.
Insensitive operation
Reason: Lack of lubricant between valve and valve seat, bent or excessive resistance of valve stem, improper installation of valve, etc.
Solution: Add an appropriate amount of lubricant, repair the valve stem or improve the installation of the valve to reduce resistance during operation.
When dealing with these faults, it is important to first conduct a detailed fault diagnosis to identify the root cause. Sometimes professional personnel may be needed for repairs or component replacements. Regular maintenance and inspection are also effective means to prevent these problems, which can extend the service life of valves and ensure the stable operation of the system.
