The invention relates to a fire-resistant protection device for an aircraft fuel tank sediment discharging valve and an aircraft. The fire-resistant protection device for the precipitation valve of the aircraft fuel tank comprises an outer fixing cover, an elastic piece, an inner sealing cover and a high-temperature-resistant sealing ring. Wherein the outer fixing cover is installed on an oil tank, the inner sealing cover comprises a lower flange, the high-temperature-resistant sealing ring is installed between the lower flange of the inner sealing cover and a lower wall plate of the oil tank, the elastic piece is installed between the inner top surface of the outer fixing cover and the lower flange of the inner sealing cover, and the outer fixing cover comprises a plurality of circulation channels located on the side face of the outer fixing cover. And the inner sealing cover adopts a full-sealing design and is used for covering the sediment discharging valve. According to the technical scheme, the fireproof sediment discharging valve has the following beneficial technical effects that the original maintenance and discharging functions of the sediment discharging valve are not affected while fireproof is achieved.
