Description

ball valve sleeve

technical field

The utility model relates to the technical field of a ball valve sleeve, in particular to a ball valve sleeve.

Background technique

The ball valve sleeve is a valve whose starting part is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid adjustment and control. Among them, the hard-sealed V-shaped ball valve has a V-shaped ball core and a metal valve with surfacing welding carbide. There is a strong shear force between the seats, especially for media containing fibers and tiny solid particles.

After retrieval, the existing patent (publication number: 201821148493.3) discloses a ferrule ball valve, which relates to the technical field of valves, and includes a valve body. A mounting hole is opened in the valve body, and a valve core is installed in the mounting hole.
