Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an anti-corrosion ball valve device. Background Art

[0002] The ball valve is driven by a hexagonal column and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which 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 on the pipeline, but also close any channel to connect the other two channels.

[0003] The existing hemispherical valve cannot replace the damaged parts inside. Most valves need to close the main gate to repair the valve when replacing the damaged parts. When the valve is damaged inside, the damaged part cannot be replaced directly. The valve needs to be replaced, which increases the time for replacing the valve, increases the company's expenditure and waste of resources. For this reason, we propose an anti-corrosion ball valve device to solve the above problems. Utility Model Content
