Abstract
The utility model discloses a double eccentric type worm wheel butterfly valve. The double eccentric type worm wheel butterfly valve comprises a pipeline connecting ring and a butterfly plate, an upper connecting cylinder is arranged on the upper side of the pipeline connecting ring, a lower connecting hole is arranged on the lower side of the pipeline connecting ring, and the butterfly plate comprises a vertical adjustment lever. The vertical adjustment lever is connected with the upper connecting cylinder and the lower connecting hole in a rotating mode. The double eccentric type worm wheel butterfly valve has the advantages that a worm wheel and worm transmission structure is arranged, operation is laborsaving and quick, and the butterfly plate can be opened and closed quickly.
