Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, the wafer type electric butterfly valve includes a valve body 1 and an electric device 2. The valve body 1 is provided with a valve stem 3 and a valve plate 4. The upper end of the valve stem 3 protrudes from the valve body 1 and is connected to the electric device 2. The electric device 2 includes an electric drive head and a connection end, and the upper end of the valve rod 3 is connected and fixed with the connection end of the electric device 2 by screws; rubber is provided between the valve plate 4 and the sealing surface of the valve body 1 Circle 6.

[0015] In this embodiment, the upper and lower ends of the valve body 1 are respectively provided with outwardly protruding connecting ribs 5 , and two bolt holes 7 are respectively opened on the upper and lower connecting ribs 5 . In this embodiment, the rubber ring 6 is a nitrile rubber ring or a fluorine rubber ring, the valve stem 3 is made of stainless steel, and the ...

Abstract

The invention relates to a double-clip type electrically operated butterfly valve. The double-clip type electrically operated butterfly valve 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 through a screw; 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 double-clip type electrically operated butterfly valve becomes compact in the valve body structure, and is more convenient to manufacture and install; the rubber ring 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 double-clip 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.

Description

technical field [0001] The invention relates to a valve, in particular to a marine wafer type electric butterfly valve. Background technique [0002] At present, the electric butterfly valve generally includes a valve body and an electric device. The valve body is provided with a valve stem and a valve plate. The upper end of the valve stem protrudes from the valve body and is connected with the electric device. The electric device includes an electric drive head and a coupling. At present, the existing marine electric butterfly valve is susceptible to corrosion due to the influence of the working environment, and leakage will occur after long-term use, thereby affecting the service life of the butterfly valve. Contents of the invention [0003] In view of the above shortcomings of the existing electric butterfly valve, the purpose of the present invention is to provide a marine wafer type electric butterfly valve with corrosion resistance and good sealing effect. [0004...
