Abstract
The utility model discloses an electric-hydraulic type light-weight ventilating butterfly valve which comprises an electric-hydraulic gyrator, a flange face structure, a valve body, a valve plate, a first valve shaft, a second valve shaft, grooves and a hard sealing ring. The electric-hydraulic gyrator is connected with the valve body through the flange face structure arranged on the valve body; the valve plate is movably connected with the valve body through the first valve shaft and the second valve shat which are arranged on the valve body, and the first valve shaft is connected on the electric-hydraulic gyrator; and the grooves are formed in the valve plate, and the hard sealing ring is arranged on the inner wall of the valve body. The number of the grooves is three; and the hard sealing rings are sealing rings made from high strength wear-resistant material. Due to the fact that the groove structures are formed in the valve plate, and the high strength wear-resistant material is adopted for making of the hard sealing ring, the electric-hydraulic type light-weight ventilating butterfly valve is enables to be simple and compact in structure, light in weight, convenient to use and maintain, good in air-locking performance, and good in practicability.
