Ball valve (ball valve). The valve (sprung) 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, in which the hard-sealed V-type ball valve has a strong shear force between the V-shaped ball core and the metal seat of the hardfacing alloy, and is particularly suitable for containing fiber and tiny solid particles. And other media. The multi-pass ball valve can not only flexibly control the confluence, diversion, and flow direction of the medium on the pipeline, but also can close any one of the channels and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. The ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.
The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. It only needs to rotate with 90 degrees of operation and a small rotating torque can close the tightness. Ball valve is the most suitable switch, shut-off valve use, V-ball valve. In addition to paying attention to the piping parameters, the electric valve should pay special attention to the environmental conditions of its use. Since the electric device in the electric valve is an electromechanical device, its use status is greatly affected by its use environment. Under normal conditions, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.
