The invention relates to an online valve sealing
surface processing machine which is characterized in that a
processing device is rotationally mounted on one side of a fixed seat, and the
processing device comprises a rotating mechanism, a radial adjusting mechanism and an axial adjusting mechanism; the rotating mechanism comprises a rotating driving
assembly and a rotating seat, and the rotating driving
assembly is fixedly mounted on the fixed seat; the radial adjusting mechanism comprises a radial adjusting seat, a radial driving
assembly and an axial adjusting seat, the radial adjusting seat is mounted on the rotating seat, the radial driving assembly is mounted on the radial adjusting seat, and the axial adjusting seat is driven by the radial driving assembly; the axial adjusting mechanism comprises an axial moving seat, an axial driving assembly and a
machining assembly, the axial moving seat is mounted on the axial adjusting seat and can axially move along the axial adjusting seat, the axial driving assembly is mounted on the axial adjusting seat and driven by the axial moving seat, and the
machining assembly is mounted on the axial moving seat. Unnecessary maintenance cost and labor waste can be reduced, the valve can be machined, maintained and repaired online, and the maintenance time of the valve is saved.
