The basic principle and application of manual butterfly valve
A manual butterfly valve is a mechanically operated valve that uses a rotating disc to control the flow of the medium. The basic principle is to rotate the disc along the axis of the valve body by manipulating the handle or gear, so as to change the flow direction and flow rate of the medium to achieve the purpose of controlling the transmission of the medium.
Manual butterfly valves are usually composed of valve body, disc, rod, seal and other components, and have obvious opening indication marks, which is convenient for users to control and maintain.
The manual butterfly valve has the advantages of simple structure, small size, light weight, long service life, convenient maintenance and reasonable price. It is widely used in petrochemical, metallurgy, electric power, pharmaceutical, light industry and other fields, especially suitable for large diameter pipelines, power stations, water treatment equipment and other occasions need to frequently adjust the medium flow application.
In short, the manual butterfly valve as an important valve type in modern industry has been widely used, and in the continuous development and progress to better meet the needs of various industries.
