[0002] Wear-resistant and corrosion-resistant super-hard ball valve is a high-performance valve product, usually used in industrial fields that need to withstand high wear and strong corrosive environments. The ball valve is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. Among them, the hard-sealed V-type ball valve has a strong shear force between the V-shaped ball core and the metal valve seat with welded cemented carbide. It is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium in the pipeline, but also close any channel and connect the other two channels.

[0003] When the ball valve is working for a long time, impurities in the fluid may remain on the bottom wall of the opening in the ball, making it inconvenient to clean the dirt. The long-term accumulation of dirt may affect the efficiency of the ball valve and reduce the effectiveness of the ball valve. Utility Model Content
