Structural characteristics of bidirectional butterfly valves:
During the opening and closing process of the butterfly plate, this butterfly valve achieves no friction and jamming between the sealing ring of the butterfly plate and the sealing surface of the valve seat. The pressure angle on the sealing surface is greater than the friction angle. It adopts a "radial dynamic balance sealing system" design, which reduces the opening resistance of the butterfly plate. During the opening and closing process, the sealing surface of the butterfly plate can be quickly and instantly completed at various points along the 360 ° circumference, with point by point contact and point by point detachment, achieving a fast and accurate sealing action that automatically matches the closing contact. The all metal hard sealed butterfly valve adopts an integral metal seal on the sealing surface, and after mechanical processing, the elliptical cross-section sealing ring forms a sealing pair with the metal sealing surface of the valve seat. This sealing structure does not produce plastic deformation under high pressure, and there is no stamping stress, welding stress, elastic annealing, or brittle cracking phenomenon under high or low temperature. It solves the problem of leakage and reliable sealing performance caused by the unreasonable sealing surface structure of traditional butterfly valves.
Applicable scope of bidirectional butterfly valve:
This valve is suitable as a closed circuit sealing device, throttling device, and regulating device in high, medium, low, high temperature, and low temperature pipelines. Widely used in industries such as petroleum, chemical, metallurgy, mining, electricity, energy, transportation, farmland, hydropower, and construction. Especially suitable for working conditions with strict sealing, such as gas pipelines, and also suitable for corrosive media such as water, steam, oil, air, electricity, dust, and acids.
