AI Technical Summary
Technical Problem
Existing ceramic ball valves are heavy and difficult to clean, requiring disassembly for internal cleaning, which affects production continuity.
Method used
An arc-shaped body is used instead of a ball valve body. Combined with upper and lower spacer rings and sealing rings, internal cleaning is achieved through a cleaning hole, avoiding disassembly.
Benefits of technology
It enables lightweight and convenient cleaning of ceramic ball valves, extending their service life without affecting production continuity.

Abstract
This invention provides a purging structure for a hemispherical valve, including a valve stem and a valve body. The valve body includes a housing and an arc-shaped body disposed within the housing. The valve stem includes an upper valve stem and a lower valve stem. The lower end of the upper valve stem is embedded in the upper end of the arc-shaped body, and the upper end of the lower valve stem is rotatably connected to the arc-shaped body. Several cleaning holes are opened near one end of the housing, and plugs are installed in the cleaning holes. An upper spacer ring is provided at the upper end of the arc-shaped body, and a lower spacer ring is provided at the bottom end of the arc-shaped body. This invention uses an arc-shaped body instead of the existing spherical valve body to reduce the overall weight of the valve. The upper and lower spacer rings can prevent backflow and liquid accumulation. When cleaning is required, the arc-shaped body is rotated to block the water inlet and open the cleaning holes. Clean water enters the internal cavity of the housing through the cleaning holes, cleaning the surface of the ceramic ball. Thus, the ceramic valve ball and its cavity can be cleaned without disassembling the ball valve, improving the service life of the ceramic ball valve without affecting production.
