Working principle and application of high pressure ball valve
High pressure ball valve is a relatively common ball valve product. At present, its application can be seen in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical industry, water conservancy and other industries. Due to the advantages of simple structure, reliable sealing and convenient maintenance, it is favored by users. Next, I will introduce the working principle and application of high-pressure ball valve.
Working principle of high pressure ball valve:
The high pressure ball valve has the action of rotating 90 degrees. The cock body is a ball and has a round 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 and a small rotating torque to close tightly. Ball valve is most suitable for switch and cut-off valve, but in recent development, ball valve has been designed to throttle and control flow, such as V-type ball valve.
Application of high pressure ball valve:
1. High pressure ball valve came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production process and product structure, in a short period of 40 years, it has rapidly developed into a major valve. In the developed countries of western countries, the use of high-pressure ball valve is increasing year by year. In China, ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, paper-making, pharmaceutical industry, water conservancy, electric power, municipal administration, steel and other industries, and plays an important role in the national economy.
2. High pressure ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Among them, the hard sealing V-type ball valve has strong shear force between the V-shaped ball core and the metal valve seat of hardfacing, which is especially suitable for the medium containing fiber and small solid particles. The multi-way ball valve can not only flexibly control the confluence, shunt and flow direction switching of medium, but also close any channel to connect the other two channels. This kind of valve should be installed horizontally in the pipeline.
