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 industrialized 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 they occupy a pivotal position in the national economy. It has a 90-degree rotating action, the plug body is a sphere, and there is a circular through hole or channel passing through its axis. The ball valve, start The closing piece (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 the V-type ball core and the metal valve seat with hard alloy overlay, 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 switching of the medium in 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. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.
