AI Technical Summary

Technical Problem

Traditional soft-seal ball valves have poor temperature resistance and weak erosion resistance when handling easily crystallizing powder media, which cannot meet the needs of industries such as chemical and metallurgical.

Method used

A hard-seal fixed ball valve is designed, comprising a valve cover, a valve seat, and a ball. The valve seat is provided with a sealing scraping part, which can scrape off the adhering material on the outer wall of the ball when rotating and switching states. Combined with elastic elements and fillers, the sealing performance and durability are improved.

Benefits of technology

It achieves efficient removal of media particles, improves the service life and long-term sealing effect of ball valves, and is suitable for high temperature and high pressure environments of easily crystallizing powder media.
