Background
The stainless steel valve seat required by the soft-sealing double-eccentric cast iron butterfly valve means that the sealing surface of a valve body in a valve sealing pair is made of stainless steel materials, and the following two methods are generally adopted to meet the requirement. The first method is welding, which includes overlaying a stainless steel layer on the sealing surface of the valve body or welding a stainless steel ring on the sealing surface, and then processing the stainless steel layer to the size and the roughness required by the design. Because the valve body is made of cast iron, including common cast iron and nodular cast iron, the welding performance is poor, strict welding process and welder technology are required, cracks are easy to occur, sealing leakage is caused, and the quality and the service life of the product are influenced. Therefore, at present, a second method is more adopted, namely mechanical fixation is adopted, a stainless steel valve seat is fixed on a valve body through a mechanical method, the valve seat is fixed on the valve body through screws, the valve seat is in sealing contact with the valve body, leakage is avoided, and the valve body and valve seat assembly structure is adopted, so that the crack phenomenon which is easy to occur in welding is avoided; therefore, it is very necessary to provide a double-eccentric soft seal butterfly valve with a sealing ring pressing plate with a countersunk head screw, which has good connection and sealing effects and is convenient to mount.
