Adjusting the valve plate height: If the discrepancy in valve elevation is minor, the issue can be resolved simply by adjusting the height of the valve plate. Specifically, the valve plate should be adjusted so that it is parallel to the central axis of the pipeline.
Replacing the valve plate: If the discrepancy in valve elevation is significant and exceeds the adjustable range, the valve plate must be replaced to ensure its height aligns with that of the other valves. This process involves dismantling the valve, installing a new valve plate, and reassembling the unit.
Repairing the valve base: If wear on the valve base has caused the valve plate elevation to be inconsistent, repairing the base is a viable solution. Repair methods include welding and machining; the specific procedures must be carried out in accordance with relevant standards.
In summary, inconsistent valve plate elevations can impair the normal operation of the piping system and require timely attention. The methods described above are for reference only; specific solutions should be determined based on the actual conditions.
