Ball valve, standard GB / T21465-2008 "Valve terminology" is defined as: opening and closing parts (spheres) driven by the stem, and around the ball valve for the rotation of the valve. It can also be used for the regulation and control of fluid. Among them, the hard seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal seat of the surfacing carbide. It is especially suitable for the use of fiber, Such as the medium. The multi-ball valve in the pipeline not only can be flexible control of the media confluence, diversion, and flow of the switch, but also can turn off any channel and the other two channels connected. This type of valve in the pipeline should generally be installed horizontally. Ball valve in accordance with the drive is divided into: pneumatic ball valve, electric ball valve, manual ball valve.Ball Valve
Ball valve came out in the 1950s, with the rapid development of science and technology, production technology and product structure of continuous improvement, in a short period of 40 years, has rapidly developed into a major valve class. In Western developed countries, the use of ball valves is increasing year by year.Ball Valve
In China, the ball valve is widely used in oil refining, long-distance pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, steel and other industries, occupies a pivotal position in the national economy. It has a 90 degree rotation action, the swivel body is a sphere, with a circular through hole or passage through its axis.Ball Valve
The ball valve is mainly used in the pipeline to cut, distribute and change the direction of flow of the media, it only needs to rotate 90 degrees of operation and a small turning torque can be closed tight. Ball valve is most suitable for the switch, cut off the valve to use, V-type ball valve. In addition to the valve should pay attention to the pipeline parameters, should pay special attention to the use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, its use of its use by the environment greatly affected. Normally, the electric ball valve, butterfly valve in the following environment to pay special attention.
