Problems solved by technology
[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved multi-channel reversing ball valve with a push-type top adjustment mechanism, which solves the problem that the ball valves currently on the market are simple in structure, difficult to operate and control. Single limitation, while the control structure applied to multi-channel ball valves is mostly a fixed structure, and the assembly status of ball valves at different channel positions cannot be adjusted according to needs, resulting in a very limited scope of application

Embodiment Construction
[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0025] figure 1 , figure 2 and image 3 A multi-channel reversing ball valve with a push-type top adjustment mechanism is shown, including a pneumatic controller 1, an adjustment motor 2, an upper valve housing 3 and a lower valve housing 4, and an upper valve housing 3 is movable inside the upper valve housing. The valve body 5 is installed, and the lower valve body 6 is movable inside the lower valve housing 4. The pneumatic controller 1 is coaxially fixed with the upper end of the upper valve body 5 through the lower longitudinal control rod 7. The center position of the upper surface of the lower valve body 6 is There is a top linkage blind hole 8, and...

The invention relates to the technical field of sealing elements, in particular to a multi-channel reversing ball valve with a pressing type top adjusting mechanism, which comprises a pneumatic controller, an adjusting motor, an upper valve shell and a lower valve shell. The multi-channel reversing ball valve with the pressing type top adjusting mechanism is formed by fixedly connecting an upper valve shell internally provided with an upper valve body and a lower valve shell internally provided with a lower valve body, and a threaded telescopic linkage mechanism controlled by a top lateral assembling cylinder is installed at the lower end of the upper valve body; therefore, the structure of the threaded telescopic linkage mechanism is freely changed, the connecting state between the upper valve body and the lower valve body is rapidly adjusted, and the control modes are more diversified. Adjustment is conducted in an overhead driving and internal transmission mode, the internal structure can be rapidly controlled while the sealing performance of the ball valve is not affected, and control and adjustment are safer and more convenient. The assembling and rotating stability of the upper valve body and the lower valve body is improved, and the sealing performance of the position of the adjusting end can be improved.
Description
technical field [0001] The invention relates to the technical field of seals, in particular to a multi-channel reversing ball valve with a push-type top adjustment mechanism. Background technique [0002] The ball valve is a valve whose opening and closing part is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. 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 and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. [0003] According to the driving mode, the ball valve is divided i...
