Description

Leakage-proof electric butterfly valve Technical Field The utility model relates to the technical field of electric butterfly valves, in particular to a leakage-proof electric butterfly valve. Background The electric butterfly valve belongs to one of electric valve and electric regulating valve. The connection mode of the electric butterfly valve mainly comprises flange type and butt clamp type, and the sealing mode of the electric butterfly valve mainly comprises rubber sealing and metal sealing. The electric butterfly valve controls the opening and closing of the butterfly valve through a power signal. The product can be used as a shut-off valve, a control valve and a check valve for a pipeline system. The conventional electric butterfly valve generally only depends on a single sealing ring to provide sealing effect at the pipeline connection position, has poor sealing performance, and easily causes gaps at the pipeline connection position, thereby causing leakage of a medium. Disclosure of utility model The utility model aims to solve the problems that in the prior art, the existing electric butterfly valve is usually only dependent on a single sealing ring to provide a sealing effect at a pipeline joint, the sealing performance is poor, gaps are easily formed at the pipeline joint, and then leakage of a medium is caused. In order to achieve the purpose, the leakage-proof electric butterfly valve comprises an electric butterfly valve assembly, wherein a shielding assembly is arranged on the outer side of the electric butterfly valve assembly, a sealing assembly is arranged on the electric butterfly valve assembly, the electric butterfly valve assembly comprises a valve body and a connecting pipe, an external pipe is connected to the inner thread of the connecting pipe, the sealing assembly comprises a first sealing ring, a sealing gasket is connected to the side face of the connecting pipe, a butt joint disc is fixedly arranged on the outer side of the external pipe, a second sealing ring is arranged on the outer side of the butt joint disc, and a hoop is clamped on the outer side of the sealing gasket. Preferably, the shielding assembly comprises a metal shielding cover and a fixing plate, a sealing gasket is arranged at the bottom of the metal shielding cover, mounting frames are mounted at two ends of the metal shielding cover, and the mounting frames are inserted into the fixing plate. Preferably, a clamping groove is formed in the sealing gasket, and the second sealing ring is movably clamped in the clamping groove. Preferably, the outer side of the sealing gasket is symmetrically provided with a limiting ring, and the first sealing ring is arranged on the surface of the connecting pipe. Preferably, the bottom of fixed plate symmetry is installed the mount, the inside movable mounting of mount has the limiting plate. Preferably, the mounting frame is provided with a limiting groove, and the limiting plate is movably arranged in the limiting groove.
