Abstract
The utility model relates to a wafer type electrically operated butterfly valve, which includes a valve body and an electric actuator, wherein a valve rod and a valve plate are arranged in the valve body; the upper end of the valve rod extends out of the valve body and is connected with the electric actuator; the electric actuator includes an electric driving head and a connecting end; the upper end of the valve rod is connected and fixed with the connecting end of the electric actuator; and a rubber ring is arranged between the valve plate and the valve body. Upper and lower ends of the valve body are provided with outwards-protruded connecting ribs respectively; and two bolt holes are formed respectively in the connecting ribs. Compared with the prior art, through arranging the outwards-protruded connecting ribs at the upper and lower ends of the valve body respectively and forming the connecting bolt holes in the connecting ribs respectively, the wafer type electrically operated butterfly valve becomes compact in the valve body structure, and is more convenient to manufacture and install; the rubber seal on the sealing surface of the valve body is a butadiene-nitrile rubber ring or a fluororubber ring, so as to be higher in abrasion resistance; and the valve rod and the valve plate are made of stainless steel, so as to be higher in corrosion resistance. The wafer type electrically operated butterfly valve has the advantages of compact structure, good sealing effect, abrasion resistance, corrosion resistance, convenience and reliability in use, and is particularly suitable for vessels on the sea.
