Description

Technical Field

[0001] The present application relates to the field of valve maintenance equipment, and in particular to an online valve sealing surface processing machine. Background Art

[0002] Valves are widely used in chemical industry, metallurgy, power station and municipal engineering. For valves in some large facilities, after use, the sealing end face of the valve seat will be damaged due to corrosion, erosion, foreign body extrusion and deformation, causing the valve to leak. For valves in these large facilities, the common method is to directly carry out offline repair and replacement, but offline repair and replacement often takes a long time. A broken valve will affect the shutdown of the entire equipment and facilities and even the entire process production line. If the repair takes too long, it will cause great losses to the unit using the valve. If there is a device that can repair the valve online without removing the entire valve and transporting it back to the repair shop, it will greatly reduce the maintenance time of the valve. At present, there are still very few equipment that can be used for online valve maintenance at home and abroad. In order to solve the pain points of this industry, we started planning to develop this kind of online valve sealing surface processing equipment many years ago. Summary of the invention
