The precision manufacturing process of the Air valve body is the key to ensure its performance and quality, which mainly includes the following important steps.
The first is the selection and inspection of raw materials. According to the design requirements and use environment of the Air valve body, select suitable metal materials, such as high-quality aluminum alloys, stainless steel, etc. These materials must have good strength, corrosion resistance and processing performance. Before being put into use, the raw materials must be strictly inspected, including chemical composition analysis, mechanical properties testing, etc., to ensure that their quality meets the standards and avoid subsequent processing problems or poor product performance due to raw material defects.
The next step is the blank forming link. Common methods include casting and forging. Casting can make the Air valve body obtain a more complex shape. During the casting process, the design and manufacture of the mold must be accurately controlled to ensure the accuracy of the cavity size. At the same time, the parameters such as pouring temperature, speed and pressure must be strictly controlled to reduce defects such as pores and shrinkage. Forging can make the material structure more compact and improve strength. During forging, it is necessary to reasonably select forging equipment and process parameters, such as forging ratio, initial forging temperature and final forging temperature, so that the blank is formed evenly and the internal quality is good.
Then comes the machining process. This is the core part of precision manufacturing, including turning, milling, drilling, boring and other operations. Turning is used to process the outer cylindrical surface and end face, and the dimensional accuracy and surface roughness must be guaranteed. Milling can process various planes and contours. When processing the valve seat, airway and other parts of the Air valve body, it is necessary to select appropriate tools and cutting parameters to achieve higher shape accuracy and surface quality. Drilling and boring are used to process various holes on the Air valve body, requiring accurate aperture size and good cylindricality. During the machining process, it is also necessary to frequently use measuring tools for measurement, and adjust the machining parameters in time to ensure that the dimensional tolerance of each part is within the allowable range.
Finally, surface treatment and assembly debugging. Surface treatment such as passivation can improve the corrosion resistance of the Air valve body, and anodizing can increase the surface hardness and wear resistance. During assembly, it is necessary to strictly follow the assembly drawing and process requirements to accurately install each part in place, such as the valve core and the valve seat to fit tightly and seal well. After assembly, strict debugging is required to test the gas flow and pressure control performance of the Air valve body under different working conditions, and timely adjust and optimize the problems found to ensure that the Air valve body can finally operate stably and efficiently to meet actual use needs.
