Description

Technical Field

[0001] This utility model relates to the field of valve core technology, and in particular to a high-sealing valve core. Background Technology

[0002] Inside the valve core, there is generally a fixed valve plate body and a fixed valve plate. The fixed valve plate body is usually rotatable or slidable, while the fixed valve plate is fixedly installed relative to the valve core housing. To prevent leakage or dripping, a seal is installed between the fixed valve plate and the valve plate mounting seat. The seal surrounds the water passage hole of the fixed valve plate, thus sealing the water passage. Currently, most valve core seals on the market use general-purpose sealing rings. These sealing rings have certain dimensional errors with the manufacturer's custom-developed fixed valve plate and valve plate mounting seat. After installation, the sealing ring may have sealing blind spots or seal failure, leading to dripping or even leakage problems in some products. Therefore, this utility model provides a valve core sealing structure with high sealing performance and a high product qualification rate. Utility Model Content
