Beschreibung
Zusammenfassung:	The invention discloses a rotary compensator for a heat supply network pipeline, which comprises an inner pipe, an outer pipe, a connecting pipe, a graphite packing and a supporting flange, and the improvements are as follows: a high-temperature medium sealing ring is arranged at one end of the graphite packing, a packing sealing ring is arranged at the other end, a labyrinth type gap is arranged in the matching position of the two sealing rings, and the surfaces/surface which are/is in contact with a compression part at two ends or one end of the graphite packing are/is circular conical surfaces/surface. The rotary compensator is used for carrying out compensation on circumferential displacement or axial displacement of a system in the heat supply network pipeline, has the outstanding advantages of high-sealing and maintenance-free properties, and can further improve the using performances and prolong the service life.
