The invention discloses a ceramic double-gate feed valve. The ceramic double-gate feed valve comprises two side flanges made of metal, a middle valve body, a graphite gasket, an O-shaped ring, a valve rod, a stuffing box assembly, a stuffing gland, a ceramic valve seat, a ceramic ring, metal disc-shaped gates, a spring seat, supporting ejector rods, a stand column, a pneumatic actuator, an inner hexagonal bolt and a double-ended bolt and nut, wherein the metal disc-shaped gates and the ceramic ring jointly form the gates of the ceramic double-gate feed valve; the ceramic ring and the ceramic valve seat form a ceramic sealing pair; the pneumatic actuator pushes the valve rod and the spring seat, and drives the gates to move up and down, so that opening and closing action of the valve is completed; in the movement process of the gates, a spring enables the gates cling to the surface of the ceramic valve seat through the supporting ejector rods, so that stable and reliable sealing is guaranteed; and meanwhile, the gates generate autoroatation during linear motion due to the function of friction force, so that the ceramic double-gate feed valve has self-grinding performance and self-cleaning performance.
