Description

Technical Field

[0001] The utility model relates to the technical field of valve ball processing, in particular to a thermal spraying device for wear-resistant treatment of the surface of a valve ball. Background Art

[0002] The ball inside the valve is a key component of a metal hard-sealed ball valve. In order to improve the surface hardness of the ball, it is usually necessary to spray some wear-resistant materials on the upper surface of the ball. However, these wear-resistant materials need to be melted and sprayed on the surface of the ball at a certain temperature. This process is called thermal spraying. In the process of thermal spraying, some metal or non-metallic coating materials are in a molten or semi-molten state, and are sprayed on the pretreated substrate surface at a certain speed with the help of compressed air to form a surface coating deposited. A valve ball thermal spraying device is required. The main procedures for thermal spraying wear-resistant materials on the outer surface of the ball include: uniformly heating the entire outer surface of the ball, heating to a certain temperature, and then uniformly spraying wear-resistant powder materials such as nickel-based alloys onto the outer surface of the ball, and then further uniformly heating the surface of the ball until the nickel-based alloy powder and other wear-resistant materials are melted to the surface of the ball, so that the wear-resistant materials are metallurgically fused with the ball substrate material, thereby ensuring that the wear-resistant coating is firm and durable.
