High temperature resistant and high pressure resistant rotary compensator

Abstract

The invention discloses a high temperature resistant and high pressure resistant rotary compensator, which comprises a rotary inner pipe, a bolt nut assembly, an outer sleeve pipe, a gland, a graphitepacking, a movable seal ring and a connecting pipe. More than two first ring grooves are formed in an outer wall of an outer convex shoulder of the right end of the rotary inner pipe; a high-temperature medium seal ring is arranged in each first ring groove, is a slip ring and is tightly matched with an inner hole of the outer sleeve pipe; and openings of the high-temperature medium seal rings ineach two adjacent first ring groove are staggered. The high temperature resistant and high pressure resistant rotary compensator has the further improvements that the movable seal ring is arranged between a left end face of an inner convex shoulder of the outer sleeve pipe in a packing seal cavity and the graphite packing; a seal structure is arranged between the movable seal ring and the inner hole of the outer sleeve pipe, the outer wall of the rotary inner pipe, and the left end face of the inner convex shoulder of the outer sleeve pipe; a wear-resistant ring is arranged between a right end face of the inner convex shoulder of the outer sleeve pipe and a left end face of the outer convex shoulder of the right end of the rotary inner pipe; an elastic self-sealing structure is arranged;and a surface, contacting the graphite packing, on the gland is a conical surface. The high temperature resistant and high pressure resistant rotary compensator provided by the invention is high temperature resistant, adopts multiple sealing structures, and is high pressure resistant.

Description

technical field [0001] The invention relates to a pipeline compensator, in particular to a rotary compensator. Background technique [0002] Rotary compensators are widely used in pipe networks for conveying high-temperature and high-pressure media due to their advantages such as convenient manufacture, large compensation amount, and high-pressure resistance. Leakage, especially when conveying high-temperature and high-pressure media, leakage will occur. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a high-temperature and high-pressure resistant rotary compensator that can significantly improve sealing reliability. [0004] The present invention achieves technical goals through the following technical solutions. [0005] High temperature and high pressure rotary compensator, including rotating inner tube, bolt and nut assembly, outer casing, gland, graphite packing, movable sealing ring and connecting pipe; the out...
