Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a flow regulating ball valve. Background Art

[0002] In the fluid medium conveying pipeline, the ball valve is an effective and necessary shutoff device. The ball valve uses a ball as the opening and closing part, and the valve stem drives the valve core to make the valve core rotate around the axis of the valve stem. The ball is also called the valve core. A through hole is provided in the ball as a flow channel. The opening of the through hole on the surface of the ball is the ball mouth. There are sealing rings tightly fitted on both sides of the ball. The sealing ring is also provided with a through hole and a sealing mouth corresponding to the ball mouth. The spherical surface between the ball and the valve seat cooperates to form a sealing spherical surface. When the ball mouth and the sealing mouth intersect, the two sides of the ball valve are connected, and the medium can enter the other end from one end of the ball valve through the flow channel. When the ball mouth and the sealing mouth do not intersect, the two sides of the ball valve are not connected, and the medium on both sides is cut off.

[0003] Valves are consumables in the pipeline system because they transport media for a long time. Existing ball valves are not equipped with filters. Due to the long-term collection and delivery of media, impurities and dirt in the media will cause blockage in the pipeline, affecting the normal use of the pipeline and causing a long maintenance time.
