AI Technical Summary
Traditional Anxi angle valves have valve cores that are either not replaceable or difficult to replace, leading to their scrapping due to erosion and wear after long-term use. Furthermore, the overall wear of the guide tube results in high replacement costs.
An electronic-grade powder respite valve was designed, which adopts a detachable upper and lower valve stem structure, combined with locking bolts and connecting seats, to achieve quick replacement of the valve core. The separate design of the guide plate and guide tube avoids local wear.
This enables quick replacement of the valve core, avoids scrapping due to wear, reduces maintenance costs, and extends service life.
