Abstract
Provided is a novel hot air expansion joint for a hot-air pipeline. An outer pipe (1) and an inner pipe (2) are arranged at butt-joint flange openings of the hot-air pipeline respectively, the inner pipe (2) is arranged in a pipeline of the outer pipe (1), opposite pipe holes are formed in the top and the bottom of a spherical expansion chamber (3) respectively, the outer pipe (1) and the inner pipe (2) are sleeved with the spherical expansion chamber (3) through the pipe holes in the top and the bottom of the spherical expansion chamber (3), the hole wall of the pipe hole in the top of the spherical expansion chamber (3) is fixedly connected with the outer pipe (1), and the hole wall of the pipe hole in the bottom of the spherical expansion chamber (3) is fixedly connected with the inner pipe (2). The novel hot air expansion joint has the advantages that compared with a corrugated pipe expansion joint, the novel hot air expansion joint is simple in structure and convenient to mount.
