Introduction Of Ball Valve
Ball Valve, the opening and closing part (ball) 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. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat of hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and 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.
The ball valve came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, it has rapidly developed into a major valve type in just 40 years. In Western industrially developed countries, the use of ball valves is increasing year by year.
In my country, ball valves are widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries, and occupy a pivotal position in the national economy. It has a 90-degree rotation action, the plug body is a sphere, and there is a circular through hole or channel passing through its axis.
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 90 degrees and a very small torque to close tightly. The ball valve is most suitable for use as a switch and cut-off valve, V-type ball valve. In addition to paying attention to the pipeline parameters, the electric valve should also 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.
