Compressor air valve dismounting tool

The utility model belongs to the technical field of compressor maintenance, and particularly relates to a compressor air valve dismounting tool which comprises a cross beam, an air valve pull rod, supporting legs and butterfly bolts, through the arrangement of the supporting legs and the butterfly bolts, the cross beam is fixed, one person can complete dismounting of an air valve, labor is saved, an air valve pad is prevented from being damaged in the dismounting process, and the working efficiency is improved. The maintenance cost is reduced, the maintenance efficiency is improved, and meanwhile, personnel and equipment are prevented from being injured due to instant falling when the air valve is separated from the cylinder body during disassembly; the cross beam is fixed through the butterfly bolts, the speed is high, and the efficiency is high; the U-shaped groove formed in the cross beam is beneficial to adjusting the crossing width of the supporting legs, and can be used for disassembling air valves with
