High-temperature medium conveying thermal insulation pipe

The utility model relates to the technical field of thermal insulation pipes, in particular to a high-temperature medium conveying thermal insulation pipe which comprises a thermal insulation pipe body. The steel frame is fixedly connected to the outer side of the thermal insulation pipe; the fixing bolt is fixedly connected to the steel frame; the rotating shaft is movably connected to the inner wall of the fixing bolt; the ball is fixedly connected to the tail end of the rotating shaft; the cavity is formed in the ball body; the closed turntable is fixedly connected to the rotating shaft; the thermal insulation layer is fixedly connected to the inner wall of the thermal insulation pipe; the anti-explosion net is fixedly connected to the outer side of the heat preservation layer; and the rubber layer is fixedly connected to the outer side of the explosion-proof net. By arranging the closing device and the leakage-proof mechanism, the thermal insulation pipe is protected, the service life of the thermal insul
