AI Technical Summary
Technical Problem
The existing ball valves have poor sealing performance during use, and the sealing ring is easily damaged, resulting in a decrease in sealing performance and affecting service life.
Method used
A double ball valve is designed, adopting a double sealing structure and protective components, including a protective ring, a semicircular scraper ring and a sealing ring. The semicircular scraper ring is used to scrape away particles on the surface of the ball, reduce the friction of the sealing ring and improve sealing performance.
Benefits of technology
It achieves stronger sealing capabilities, extends the service life of the ball valve, reduces the probability of failure, and improves the overall performance of the valve.
