Forged steel butterfly valves are suitable for high temperature resistance, high pressure resistance, corrosion resistance, wear resistance and other industries; among them, the three-eccentric metal-to-metal structure, the valve seat and the valve plate sealing ring are fixed between the adjusting pressure ring and the spring and the pressure plate adjusting bolt assembly Structure, this structure effectively compensates for the tolerance between the shaft sleeve and the valve body and the automatic adjustment of the valve seat under the medium pressure, which solves the sealing problem of the valve in the two-way interchangeable medium conveying process. The valve seat and the sealing surface layer are welded with temperature-resistant and corrosion-resistant alloy materials. Compared with the traditional butterfly valve, this kind of butterfly valve has the advantages of high temperature resistance, light operation, no friction when opening and closing, and the sealing performance of the butterfly valve is improved and the service life of the butterfly valve is improved as the torque of the transmission mechanism increases when closing. It can replace gate valves, high temperature butterfly valves and spherical
