About the history of the ball valve
The rapid development of science and technology, production technology and product structure of continuous improvement in a short span of 40 years, has rapidly developed into a major valve class.
In the western industrialized countries, the use of ball valve is constantly rising. In China, ball valve is widely used in petroleum refining, long-distance pipeline, chemical, papermaking, pharmacy, Water Conservancy, power, municipal, steel and other industries, occupy a pivotal position in the national economy.
It has a rotational 90 degree movement, the plug body is a sphere, there is a circular through hole or channel through its axis. Ball valve in the pipeline is mainly used to cut, distribute and change the flow direction of the media, it only needs to rotate 90 degrees of operation and very small rotational torque can be closed tight. Ball valve is most suitable for switching, shut-off valve use, V-type ball valve. In addition to the electric valve should pay attention to the pipe parameters, should pay special attention to its use of environmental conditions, because the electric valve in the electric device is an electromechanical equipment, its use of the State by its use of the environment has a great impact. Usually, the electric ball valve, butterfly valve in the following environment to pay special attention to the use.
