The working principle, advantages and wide application of butterfly valves

First, the working principle of butterfly valve

The butterfly Valve is a kind of valve with a disc opening and closing piece that reciprocates about 90° to open, close and adjust the fluid passage. The opening and closing parts of the butterfly valve are in the shape of a disc, and the valve is opened and closed by rotating the disc. In the open state, the disc is parallel to the axis of the pipeline, and the fluid can pass smoothly; In the closed state, the disc is perpendicular to the axis of the pipe, preventing the fluid from passing through.

SEcond, the advantages ofbutterfly valves

1. Simple structure, small size and light weight: The structure of the butterfly valve is relatively simple, mainly composed of disc, valve body and valve shaft, so it is small in size, light in weight, saves materials, and is especially suitable for large-diameter valves.
2. Rapid opening and closing, small flow resistance: The opening and closing parts of the butterfly valve are in the shape of a disc, and the rapid opening and closing can be achieved by rotating 90°, and the flow resistance is small, which is conducive to the smooth flow of fluid.
3. Wide range of application: Butterfly valve can be used for media with suspended solid particles, and can also be used for powder and granular media according to the strength of the sealing surface. At the same time, the butterfly valve is also suitable for the two-way opening and closing and adjustment of ventilation and dust removal pipelines, and is widely used in gas pipelines and waterways in metallurgy, light industry, electric power, and petrochemical systems.

Fourth, the application scenario of butterfly valve

1. Ventilation and dust removal pipeline: The butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipeline, which is conducive to maintaining the smooth flow of the pipeline and improving the ventilation and dust removal effect.
2. Metallurgy, light industry, electric power, petrochemical system: butterfly valves are widely used in metallurgy, light industry, electric power, petrochemical system gas pipelines and waterways, etc., to meet the transportation needs of different media.
3. Media with suspended solid particles: Butterfly valve is suitable for media with suspended solid particles, and can also be used for powder and granular media according to the strength of the sealing surface, which is conducive to protecting the pipeline system and preventing pipeline blockage.
4. Conclusion

As a common type of valve, butterfly valves play an important role in industrial piping systems. Understanding the working principle, advantages and disadvantages of butterfly valves, and application scenarios will help us better select and use butterfly valves to improve the operational efficiency and safety of pipeline systems. In the actual project, the butterfly valve should be reasonably selected according to the specific working conditions and needs, and attention should be paid to regular maintenance and overhaul to ensure the normal operation of the butterfly valve.
