In our country, ball valves are widely used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries, and occupy a pivotal position in the national economy. It has the action of rotating 90 degrees, the cock body is a sphere, with a circular through hole or channel passing through its axis. The ball valve is a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid adjustment and control. Among them, the hard-sealed V-shaped ball valve has a strong shear force between the V-shaped core and the metal seat of the hard alloy surfacing.
It is especially suitable for fibers and small solid particles. And other media. The multi-way ball valve can not only flexibly control the confluence, divergence, and switching of the flow direction 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.The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque can be closed tightly. The ball valve is most suitable for use as a switch and shut-off valve, V-shaped ball valve. In addition to paying attention to pipeline parameters, electric valves should also pay special attention to the environmental conditions in which they are used.
