Abstract
The utility model belongs to the field of integrated butterfly valves with multiple leakage-proof structures, and particularly relates to an integrated butterfly valve with multiple leakage-proof structures, which comprises a first valve body, a second rubber ring is arranged in the first valve body, and a butterfly valve plate is mounted on the second rubber ring. The outer wall of the butterfly valve piece is tightly attached to the inner wall of the second rubber circular ring. The bottom of the butterfly valve piece is transversely connected with a second rotating shaft, the second rotating shaft penetrates through a second rubber ring and an opening in the side wall of the first valve body, the second rotating shaft is connected with the output end of a motor, fixing blocks arranged on the outer wall of the first valve body correspond to fixing blocks arranged on the outer wall of the second valve body, and circular holes are formed in the fixing blocks. By means of the structure, opening and closing of the valve are driven by electric power, the leakage-proof performance of the device is improved in cooperation with rubber, and the practical performance of the device is improved.
