Description

Connecting ball valve

Technical Field

The utility model relates to the field of ball valves, in particular to a connecting ball valve.

Background

The ball valve, the opening and closing piece (sphere) is driven by the valve rod and rotates around the axis of the ball valve. The device can also be used for regulating and controlling fluid, wherein the hard seal V-shaped ball valve has strong shearing force between the V-shaped ball core and the metal valve seat of the hard alloy for surfacing, and is particularly suitable for mediums containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the flow direction switching of the medium on the pipeline, and simultaneously can close any channel to connect the other two channels. The valve should be installed generally horizontally in the pipeline. The ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball.

When the existing manual ball valve is used, the operator only needs to feel to rotate because of no feedback mechanism when the flow is adjusted in a rotating way, so that inaccurate phenomenon is avoided, and multiple adjustment is needed.

In order to solve the above problems, the present utility model provides a connecting ball valve.
