Description

Technical Field

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

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat welded with hard alloy, 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 switching of the flow direction of the medium on the pipeline, but also close any channel and connect the other two channels. The existing ball valves all adopt an integrated structure, which means that when the parts inside the ball valve are damaged, the entire ball valve needs to be replaced, and the user cannot disassemble the ball valve for maintenance, thereby reducing the service life of the ball valve. Therefore, those skilled in the art provide a ball valve that is easy to repair to solve the problems raised in the above background technology. Utility Model Content
