Description

Technical Field

[0001] The utility model belongs to the technical field of ball valves, in particular to a ball valve which is easy to clean. Background Art

[0002] Ball valve, the opening and closing part (ball) 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. 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.

[0003] In the prior art, when the ball valve is in use, more debris will be absorbed into the through hole of the ball over time, which can easily cause the ball valve to be blocked. The ball valve needs to be disassembled and cleaned, but the disassembly and cleaning of the ball valve is relatively cumbersome and troublesome, and is inconvenient to use.
