Description

A ball valve assembly equipment

technical field

The invention belongs to the technical field of ball valve assembly, in particular to a ball valve assembly equipment.

Background technique

Ball valve, the 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 fluid regulation and control, among which the hard-sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the hard-facing metal valve seat, and is especially suitable for media containing fibers and tiny solid particles. 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. According to the driving mode, the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.

In the prior art, when assembling the ball valve, the ball needs to be inserted into the half valve body.

The process of manually picking up the ball needs to find the side where the gap of the ball is aligned with the valve stem. The overall assembly process will take a long time, thereby reducing work efficiency and increasing staff labor burden.
