High pressure ball valve definition: High pressure ball valve in the "valve terms" GB / T21465-2008 is defined as: opening and closing pieces (ball) by the valve stem, and the shaft around the axis of rotation of the valve. With the rapid development of science and technology, the continual improvement of production technology and product structure has rapidly developed into a major type of valve in 40 short years. In the developed countries of western countries, the use of high-pressure ball valves is increasing year by year. In China, ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical, water conservancy, electricity, municipal administration, steel and other industries , Occupying a pivotal position in the national economy. High-pressure ball valve is mainly used to cut off or connect the media in the pipeline, can also be used for fluid regulation and control, including the V-ball valve with hard-sealed V-shaped core and hardmetal welding metal seat between the strong Shear, especially for containing fibers, small solid particles and other media. The multi-pass ball valve in the pipeline can not only flexibly control the merging of media, diversion, and flow switching, but also can close any channel and the other two channels connected. This type of valve in the pipeline should be generally horizontal installation. High-pressure ball valve works: High-pressure ball valve which has the action of rotating 90 degrees, the cock body is a sphere, a circular through-hole or passage through its axis. Ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small turning moment can be closed tight. Ball valves are best suited for switching and shut-off valves, but recent developments have designed ball valves to provide throttling and control flow, such as V-ball valves. The main features of high-pressure ball valve itself is compact, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often closed state, easy to be media erosion, easy to operate and repair, suitable for water, solvents, acids and natural gas, etc. Working medium, but also for poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., are widely used in various industries. Ball valve body can be a whole, it can be combined. High pressure ball valve advantages: 1. Small fluid resistance, full diameter of the ball valve basically no flow resistance. 2. Simple structure, small size, light weight. 3. Close and reliable. It has two sealing surfaces, and the ball valve sealing surface material widely used in a variety of plastic, good sealing, can achieve a complete seal. In the vacuum system has also been widely used. 4. Easy to operate, quick opening and closing, as long as 90 ° rotation from full open to full close, easy to remote control. 5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient. 6. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface. 7. Wide range of applications, the path from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. 8. Because the ball valve in the process of opening and closing wipe, it can be used for medium with suspended solid particles.
