< >< adopts centerline disc and short It is designed and manufactured with a new structural form welded by structural steel plates. It has a compact structure, light weight and easy installation. It has small flow resistance and large flow capacity. It avoids the influence of high temperature expansion and is easy to operate. There are no connecting rods, bolts, etc. in the body, so it works reliably and has a long service life. It can be installed at multiple stations and is not affected by the flow direction of the medium.
At present, fluorine-lined butterfly valves and rubber-lined butterfly valves, as components used to realize on-off and flow control of pipeline systems, have been widely used in many fields such as petrochemical industry, metallurgy, hydropower, etc. In the known butterfly valve technology, the sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitations of structural characteristics, it is not suitable for industries such as high temperature and high pressure resistance, corrosion resistance and wear resistance. An existing relatively advanced butterfly valve is a triple-eccentric metal hard-seal butterfly valve. The valve body and valve seat are one-piece components, and the sealing surface layer of the valve seat is overlay-welded with temperature-resistant and corrosion-resistant alloy materials. Multi-layer soft stacked sealing rings are fixed on the valve plate. Compared with traditional butterfly valves, this kind of butterfly valve has high temperature resistance, is easy to operate, and has no friction when opening and closing. When closing, the torque of the transmission mechanism increases to compensate for the seal, which improves the performance of the butterfly valve. Excellent sealing performance and extended service life.
