AI Technical Summary

Technical Problem

The existing aluminum alloy valve body, after being integrally die-cast, has many burrs and is thin in the first protrusion, making it prone to breakage. It is also easy to react with oxygen and water vapor in the air, leading to corrosion, which affects service life and mechanical properties.

Method used

The shell structure is designed using an integrated die-casting process, with positioning notches and backing plates to reduce material usage and improve corrosion resistance through a passivation film. At the same time, a simple connection structure is designed to avoid reverse installation, and mating sleeves and positioning holes are used to ensure correct installation.

Benefits of technology

This technology enables the aluminum alloy valve body to be used conveniently, reduces manufacturing costs, improves mechanical properties and corrosion resistance, avoids incorrect installation, and reduces production costs.
