进口四偏心高性能蝶阀-美国阿卡迪亚品牌

进口四偏心高性能蝶阀Product Description:

In particular to the technical field of eccentric butterfly valves. The valve body comprises a valve body, a butterfly plate, a valve stem, a valve seat, a sealing ring, a pressure plate ring and a screw. A valve seat arranged obliquely is installed outside the butterfly plate; The axis line of the valve stem and the center line of the flow channel of the valve body form an included angle, the axis of the conical sealing surface forms an included angle with the axis line of the valve stem, the rotation center of the conical sealing surface forms an included angle with the center of the flow channel of the valve body, and the axis of the conical sealing surface forms an included angle with the center axis of the valve body. It overcomes the problems of the three eccentric butterfly valve in the prior art that the valve seat and the medium flow direction are perpendicular to each other, the operating torque is large when opening and closing, the switching angle is large and the sealing performance is poor. The utility model is to modify the valve seat of the traditional three eccentric butterfly valve, change the original vertical valve seat to the inclined valve seat, so as to generate an eccentricity, reduce the valve opening and closing torque, reduce the valve opening and closing time, and increase the sealing reliability.

进口四偏心高性能蝶阀characteristic:

The four eccentric high-performance butterfly valve comprises a valve body, a butterfly plate, a valve stem, a valve seat, a sealing ring, a pressure plate ring and a screw. The valve body is provided with a valve flow channel, the butterfly plate is arranged in the valve flow channel, the pressure plate ring is fixed on the butterfly plate by screws, and a sealing ring is arranged between the butterfly plate and the pressure plate ring. The left side of the valve seat and the right side of the seat are not arranged on the same horizontal line, and the connecting line between the sealing ring and the center of the valve seat forms a conical sealing surface, The valve stem is arranged inside the butterfly plate and drives the butterfly plate to rotate. The axis of the valve stem and the center line of the valve channel of the valve body form an eccentric included angle a, the axis of the conical sealing surface and the axis line of the valve stem form an eccentric included angle B, the rotation center of the conical sealing surface and the center of the valve channel form an eccentric included angle c, and the axis of the conical sealing surface and the center axis of the valve body form an eccentric included angle D.
