Embodiment Construction

[0036] The specific implementation of the present invention will be described below in conjunction with the drawings and examples.

[0037] Such as figure 1 and figure 2As shown, including right valve body 1, valve plate 2, lower driven valve stem 3, valve seat 4, driven magnet 5, left valve body 6, driving magnet 7, driving gear 9, driving valve stem 10, driven gear 13 and the upper driven valve rod 14; the fluid flows along the direction from the left valve body 6 to the right valve body 1; The lower part of the inside of the right valve body 1 is provided with a flow path chamber for flow, which constitutes the valve chamber of the valve. The inside of the left valve body 6 and the right valve body 1 are all provided with a flow chamber for fluid communication. The left valve body 6 and the right valve body 1 The circulation cavity is just butted and matched; the left valve body 6 and the right valve body 1 above the valve cavity are provided with holes to form the struc...

Abstract

The invention discloses a novel magnetic active sealing butterfly valve. A valve body is formed by a left valve body part and a right valve body part, a valve cavity is formed in the lower portion, and a structure installation cavity is formed in the upper portion. A valve plate is installed in the valve cavity, an annular inner boss is arranged in the middle of the valve cavity, an annular movable groove is formed in the side, close to the valve plate, in the annular inner boss, a driven magnet and a valve seat are installed in the annular movable groove, a driving magnet is installed in theannular inner boss, a driving gear is installed in the structure installation cavity, a driven gear is installed in the structure installation cavity, the two ends of a driving valve rod are connectedwith the driving gear and the driving magnet, and the driving gear and the driven gear are incomplete gears, have circular gear parts and circular arc gear part matched with the circular gear parts and form an intermittent structure. By designing the magnetic driving sealing device with the active sealing function, the sealing effect of the valve is improved, the service life of the valve is prolonged, and meanwhile the safety in an emergent state is enhanced.

Description

technical field [0001] The invention relates to a valve structure, in particular to a novel magnetic active sealing butterfly valve. Background technique [0002] Butterfly valve, also known as flap valve, is an important regulating valve in fluid transmission system, widely used in aerospace, petrochemical, water conservancy and hydropower and other fields. Its opening and closing part is a disc-shaped butterfly plate, which can realize the functions of opening, closing and adjustment by rotating the butterfly plate around its axis. It can be used to control the flow of various fluids such as water, air, high-pressure steam, mud, corrosive and radioactive media, and plays a vital role in the safety, speed and accuracy of the pipeline system. Due to the thinness of the butterfly valve itself, the sealing performance in the closed state is an important indicator of its reliability. At present, the sealing method of butterfly valve mainly uses the inclined valve seat surface...
