Description

Technical Field

[0001] This invention relates to the field of valve spraying process equipment technology, specifically a wear-resistant valve spraying process. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are commonly used in various environments, including humid and corrosive media. Applying a corrosion-resistant coating can improve the valve's resistance to corrosion and extend its service life.

[0003] Application number 202111521338.8 discloses a wear-resistant valve coating process. The process involves rounding the corners of the valve body's three-way and four-way bearings, assembling the valve body, sealing rings, and pressure rings, protecting the sealing surface of the sealing rings, coating the valve body's internal channels and the shaft holes of the three-way and four-way bearings with tungsten carbide, protecting the machined valve plate sealing surface and shaft holes, coating the valve plate surface with tungsten carbide, machining the valve shaft's contact area with the medium, coating the machined areas with tungsten carbide to a thickness of 0.3 mm, and then automatically grinding the coated areas. The beneficial effect of this invention is that it improves the overall wear resistance of the valve's internal components and extends its service life.

[0004] While this design improves the overall wear resistance of the valve's interior and extends its service life, it also generates dust during the valve painting process. This design lacks corresponding cleaning and collection devices during valve painting, requiring the dust to be cleaned and centrally processed. Therefore, it is necessary to install appropriate cleaning and collection structures during valve painting to handle the dust, thereby reducing manual cleaning and improving work efficiency.
