Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a top-mounted inclined surface tight ball valve. Background Art

[0002] Ball valve is a valve whose 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. 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 to connect the other two channels.

[0003] In pipelines for fluid media such as petroleum and petrochemical, long-term shutdown of some process pipelines is not allowed. Ordinary valves have the disadvantage of being difficult to disassemble and repair. Therefore, top-entry ball valves are used to replace traditional valves in the prior art. Top-entry ball valves have the advantage of opening the valve cover to remove internal components and achieve quick maintenance.

[0004] Most of the existing ball valves have only one channel, and a ball core is arranged in the channel to control the internal flow medium. Such ball valves have a single usage mode and a small application range, and can only realize the flow of media in the same direction. Utility Model Content
