      Electric tri-eccentric butterfly valve is composed of rotary electric actuator and tri-eccentric butterfly valve body. The valve body adopts tri-eccentric metal hard sealing structure. The valve seat and sealing surface are made of stainless steel. It has good corrosion resistance and bidirectional sealing function. The friction between the butterfly plate and the valve seat of electric tri-eccentric butterfly valve is less and the life is longer. It has wide application scope and convenient maintenance. Electric tri-eccentric butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, steel, paper, medicine, food, textile, light industry and other industries.


      Main features of electric three eccentric butterfly valve


      1. The valve adopts three eccentric sealing structure, and the valve seat and butterfly plate wear little.


      2. The sealing ring is made of stainless steel. It has the double advantages of hard metal sealing and elastic sealing. It has excellent sealing performance, corrosion resistance and long service life, no matter at low and high temperature.


      3. Butterfly plate sealing surface is made of cobalt base cemented carbide, the sealing surface is wear resistant and has long service life.


      4, large diameter butterfly plate adopts quilting structure, high strength, large flow area and small flow resistance.


      5. Electric tri-eccentric butterfly valve has two-way sealing function. It can be installed in any direction without the restriction of the flow direction of medium or the influence of space position.


      6, the driving device can be installed at multiple stations (rotating 90 degrees or 180 degrees) for user convenience.

      Three eccentric sealing principle of electric three eccentric butterfly valve




      Since the center line of the seat is then formed at a beta angle with the center line of the valve body on the basis of the double eccentric sealing butterfly valve, the offset result can be seen from the A-A section of Fig. 2. When the triple eccentric hard sealing butterfly valve is fully opened, the butterfly plate seal surface will completely detach from the seat seal surface, and the butterfly plate seal surface and the butterfly plate seal surface will be completely open. A clearance Y is formed between the sealing surfaces of the valve body and that of the double eccentric sealing butterfly valve. It can be seen from the diagram that the tangent of the turning trajectory of the sealing surface of the butterfly plate and the sealing surface of the valve seat form an angle of theta 1 and theta 2 due to the formation of the position of the beta angle. When the butterfly plate opens and closes, the sealing surface of the butterfly plate gradually disengages from the sealing surface of the valve seat and gradually presses in, thus completely eliminating the mechanical wear and abrasion between the two sealing pairs of the butterfly valve when the butterfly plate opens and closes. When the butterfly valve is opened from 0 degrees to 90 degrees, the sealing surface of the butterfly plate will immediately detach from the sealing surface of the valve seat at the moment of opening. When the butterfly valve is closed from 90 degrees to 0 degrees, the sealing surface of the butterfly plate will contact and press the sealing surface of the valve seat only at the moment of closing.
