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.
The ball valve is most suitable for the switch, cut off the valve to use, but the recent development of the ball valve has been designed so that it has a throttle and control flow, such as V-ball valve.
The main features of the ball valve is its own compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, not easily eroded by the media, easy to operate and maintenance, suitable for water, solvents, acids and natural gas and other general work Medium, but also for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene, in various industries have been widely used.
Ball valve body can be integrated, it can be modular.
The development of the ball valve The advent of the ball valve in the 20th century, 50 years, with the rapid development of science and technology, production technology and product structure of the continuous improvement in a short period of 40 years, has rapidly developed into a major valve class.
In the industrial countries of Western countries, the use of ball valves is increasing year by year, in China, the ball valve is widely used in oil refining, long-distance pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, steel and other industries, In the national economy occupies a pivotal position.
Ball valve is mainly used for cutting off or connected to the medium in the pipeline, can also be used for fluid regulation and control, which hard seal V-ball valve V-core and surfacing carbide metal seat between the strong Shear force, especially for fiber, micro-solid particles and other media.
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.
The main advantages of the ball valve.
Fluid resistance is small, full diameter ball valve is basically no flow resistance.
2.
Simple structure, small size, light weight.
3.
Close and reliable.
It has two sealing surface, and the current ball valve sealing surface material widely used in a variety of plastic, good sealing, to achieve a complete seal.
In the vacuum system has also been widely used.
4.
Easy to operate, open and close quickly, from full open to full clearance as long as the rotation 90
