Three-piece slurry valves, a key piece of equipment in the mining and chemical industry, often fail due to wear and corrosion. The exhibition will reveal its repair steps and practical applications, and we will ask: how to ensure the stable operation of the slurry valve? How can I extend its useful life by repairing it?
Three tabletsformulaApplication of slurry valves
The three-piece slurry valve is mainly composed of valve body, valve plate and valve strip and other components, and adopts a three-piece structure design, which has good sealing performance and wear resistance. In mining and chemical production, three-piece slurry valves are widely used to convey slurry, slurry and other fluid media containing solid particles. By controlling the opening and closing of the valve, the slurry flow, pressure and other parameters can be adjusted to meet the needs of the production process.

Disassembly and cleaning: First, remove the worn valve from the pipeline, and clean up the rust and impurities on the valve surface and sealing surface. Use a tool to remove the disc and strip for further inspection and repair.
Inspection & Evaluation: Carefully inspect the wear and corrosion of the valve body, valve plate, valve bar and other components, and evaluate the parts and extent that need to be repaired. For areas that are heavily worn or corroded, appropriate repair measures are required.
Repair and refill: According to the results of inspection and evaluation, repair and fill the worn or corroded parts. It can be repaired by surfacing welding, spraying, etc., and the key parts can be strengthened with wear-resistant materials.
Grinding and polishing: Grinding and polishing the repaired valve plate and valve strip to ensure that the sealing surface is flat and smooth to improve sealing performance. At the same time, the sealing groove of the valve body is trimmed to ensure that its size and shape meet the requirements of the original design.
Assembly and pressure test: The repaired parts are assembled according to the original design, and the pressure test is carried out. Check that the valve is able to open and close properly and that there are no leaks. If everything is in order, the valve repair can be considered complete
Conclusion
The repair of the three-piece slurry valve is a highly technical task that requires the corresponding professional knowledge and skills. Through the disassembly, cleaning, inspection, repair, grinding, polishing, assembly and pressure test of the valve, the performance of the valve can be effectively restored, its service life can be prolonged, and the production cost can be reduced. In practical application, the three-piece slurry valve should be inspected and maintained regularly, and potential faults should be found and dealt with in time to ensure its normal operation and improve production efficiency.
