Abstract

The invention relates to the technical field of butterfly valves, and discloses an industrial steam intelligent control electric butterfly valve which comprises a valve body, an electromagnetic ring is embedded in the inner wall of the valve body, a sealing mechanism is fixedly installed on the inner wall of the valve body and comprises a valve seat, and a rubber ring is fixedly connected to the inner wall of the valve seat. The periphery of the rubber ring is fixedly sleeved with a metal soft ring, the left end of the valve seat is slidably connected with a magnetic ring in an inserted mode, the rear end of the valve body is movably connected with an adjusting mechanism, the adjusting mechanism comprises a worm, and the periphery of the worm is fixedly connected with an electric block. According to the industrial steam intelligent control electric butterfly valve, when the valve plate is closed, high pressure on the steam side is used for automatically providing high extrusion force between the rubber ring and the valve plate, and when the valve plate is opened, the rubber ring is controlled in advance to automatically reduce the extrusion force; therefore, the sealing abrasion is effectively reduced, the subsequent sealing quality is ensured, and the overall use stability of the valve is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of butterfly valves, in particular to an electric butterfly valve with intelligent control of industrial steam. Background technique

[0002] Existing electric butterfly valves for industrial steam always install the sealing ring on the valve seat during use. When the valve plate is closed, it can be fully squeezed with the sealing ring to achieve the effect of filling the connection gap. However, when the valve plate is closed, its edge will preferentially squeeze with the edge of the sealing ring, which will lead to The tangential hard extrusion deformation occurs, and when the valve plate is opened, the sealing ring will be hard extruded again, which will lead to serious wear of the sealing ring in the long run, greatly affecting its service life, and the sealing ring is fully Compression will cause the problem of large opening and closing torque, which is not conducive to the stability of the overall us...
