Description

Technical Field

[0001] The present application relates to the technical field of ball valves, and in particular to a ball valve that is convenient for filtering. Background Art

[0002] At present, the working principle of the ball valve is to control the flow of fluid by rotating the ball. Specifically, the opening and closing part of the ball valve is a ball with a circular channel. The ball is driven by the valve stem and rotates around the axis of the ball valve. During the opening and closing process, the ball rotates around its central axis. When the ball rotates to a specific position (usually 90°), the hole on it will align or stagger with the channel of the valve body, thereby achieving the flow of fluid.

[0003] The ball valve in the prior art generally comprises a valve body, a spherical valve core and a handle connected to the spherical valve core.

[0004] However, large ball valves are generally not provided with filters, so when the ball valve is blocked, it is inconvenient to clean the ball valve because the large ball valve is inconvenient to disassemble and assemble. Summary of the invention
