AI Technical Summary

Technical Problem

During the use of existing valve ball thermal spraying equipment, the spray unit has poor adjustment, resulting in uneven coating thickness, which in turn leads to aggravation of local wear of the ball, reducing the thermal spraying effect of the valve ball, and insufficient storage effect of the spray material. Stablize.

Method used

A valve ball thermal spraying equipment including a body, a cover, a heating mechanism, a clamping fixing mechanism, a control unit, a spraying mechanism and a coating storage mechanism is designed. The spraying nozzle can be moved horizontally along the width and length of the body to adjust the spraying position. Combining air-cooling, water-cooling and insulation components, the coating temperature is maintained stable, and the coating uniformity is maintained through the stirring components.

Benefits of technology

Effectively adjust the position of the spray nozzle to prevent uneven coating thickness, maintain the optimal spray temperature and uniformity of the coating, and improve the thermal spraying effect of the valve ball.
