The invention provides an anti-resonance large-diameter triple-eccentric metal hard sealing butterfly valve, which relates to the technical field of butterfly valves, and comprises an outer cylinder, a base, a top cover, an oil cup and an anti-vibration cylinder, a clamping groove is formed in the inner wall of the outer cylinder, two sets of grooves are formed in the left end and the right end of the outer cylinder, and sealing rings are installed in the grooves. The base is installed at the upper end of the outer cylinder through bolts, a worm wheel shaft is connected to the base through a shaft, and a worm wheel on the worm wheel shaft is one fourth of a common worm wheel. The position of the cleaning roller is adjusted by unscrewing a butterfly nut, so that the cleaning roller is in contact with the worm, when the worm is rotated, the cleaning roller can sweep dust on the worm, and the situation that the worm is difficult to rotate due to the fact that the worm is covered with the dust is prevented; when
