La description

use
Double eccentric butterfly valve, also known as high-performance butterfly valve, is mainly applicable to water plants, power plants, steel smelting, chemical engineering, water source engineering, environmental facilities construction and other systems for drainage, especially suitable for watercourse pipeline, as a regulation and closure equipment.Compared with the center line butterfly valve, double eccentric butterfly valve is more resistant to high pressure, longer life and better stability.The larger the diameter, the lighter the material, the lower the cost compared to other valves.However, as there is a butterfly plate in the middle, the flow resistance is large, so butterfly valve less than DN**0 is of no great significance.
working principle
Double eccentric butterfly valve is further improved on the basis of single eccentric butterfly valve.The structure is characterized by that the valve stem axis deviates from both the disc center and the body center.The double eccentric effect enables the butterfly plate to detach from the seat immediately after the valve is opened, greatly eliminating unnecessary excessive squeezing and scraping between the butterfly plate and the seat, reducing the opening resistance distance, reducing wear and increasing the life of the seat.The greatly reduced scraping also enables double eccentric butterfly valves to use metal seats, improving the application of butterfly valves in the high temperature field.
Structural characteristics
1. Reasonable design, compact structure, easy installation and disassembly, easy maintenance.
2.Adopt eccentric structure, reduce the friction of sealing ring, and prolong the service life of valve.
3.Completely sealed with zero leakage.It can be used in ultra high vacuum condition.
4.Replace valve plate sealing ring, butterfly plate, rotating shaft and other materials, suitable for a variety of media and different temperatures.
