Embodiment Construction
[0018] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0019] The explosion-proof and high-pressure resistant rotary compensator shown in the accompanying drawings includes a different-diameter outer tube 1, a rotating inner tube 2, an outer tube 5, a gland 9 and an explosion-proof tube 12; The middle part of the inner hole of the tube 5 is provided with an inner shoulder 5.1; the outer sleeve 5 is set on the rotating inner tube 2 from right to left; 5 The inner hole and the outer wall of the rotating inner tube 2 form a first sealed cavity, and a sealing ring 4 is arranged in the first sealing cavity. In this embodiment, metal anti-friction rings 3 are arranged on both sides of the sealing ring 4 .
[0020] The gland 9 is set on the outer wall of the right end of the rotating inner tube 2, and is connected to the right end surface of the outer casing 5 by a bolt 11. In this embodiment, a b...

The invention discloses an anti-explosion and high-pressure-resisting rotation compensator. The anti-explosion and high-pressure-resisting rotation compensator comprises a different-diameter outer pipe, a rotation inner pipe, an outer casing pipe, a gland and an anti-explosion pipe. The left segment of the outer wall of the rotation inner pipe is provided with an outer protruding shoulder, and an inner protruding shoulder is arranged in the middle of an inner hole of the outer casing pipe. The outer casing pipe is arranged on the rotation inner pipe from right to left in a sleeved mode to form a first sealing cavity and a second sealing cavity. An elastic self-sealing structure is arranged in the second sealing cavity, and the rotation inner pipe is an axial step type structure of which the diameter is gradually reduced from the outer protruding shoulder to the right side. The diameter of the matched position of the rotation inner pipe and the anti-explosion pipe is smaller than the diameter of the matched position between the rotation inner pipe and the gland. Bushings are arranged at the matched position of the rotation inner pipe and the inner protruding shoulder of the outer casing pipe and at the matched position of the rotation inner pipe and the matched position of the rotation inner pipe and the anti-explosion pipe. A rolling support is adopted. The two sides of a sealing ring in the first sealing cavity are provided with metal antifriction rings. According to the anti-explosion and high-pressure-resisting rotation compensator, an anti-explosion structure is simplified, production cost is effectively reduced, operation is flexible, and the anti-explosion and high-pressure-resisting rotation compensator is resistant to high pressure and durable and reliable in sealing.
Description
technical field [0001] The invention relates to a pipeline compensator, in particular to a rotary compensator. Background technique [0002] The existing structure of the rotary compensator has only one end face sealing structure, which can fully meet the requirements of use under normal circumstances, but from the perspective of safety, especially in some high-temperature and high-pressure pipelines and pipelines with frequent temperature changes and strict prevention of leakage There will be certain safety hazards during use. When the step surface of the inner pipe is subjected to alternating stress for a long time and breaks, the inner pipe will be separated from the outer pipe under huge pressure, resulting in a safety accident. Chinese Patent Application Publication No. CN102359690A discloses a "safe explosion-proof self-sealing rotary compensator", which includes an outer tube with a different diameter and an inner tube, one end of the inner tube is positioned in the o...
