Development of ball valves
Ball valve (ball valve) was introduced in the 1950s, with the rapid development of science and technology, production processes and product structure continue to improve, in just 40 years, has rapidly developed into a major valve category. In the western industrial countries, the use of ball valves is rising year by year.
In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. It has the action of rotating 90 degrees, and the plug body is a sphere with a circular through-hole or channel through its axis.
Ball valve in the pipeline is mainly used to do cut off, distribution and change the flow direction of the medium, it only needs to operate with 90 degrees of rotation and a very small turning torque to close tightly. Ball valve is most suitable for use as a switch, cut-off valve, V ball valve. Electric valve should pay attention to the pipeline parameters, but also should pay special attention to the environmental conditions of its use, because the electric device in the electric valve is an electromechanical device, the use of its state is greatly affected by its use of the environment.
Usually, electric ball valves, butterfly valves in the following environment use to pay special attention.
