Abstract

The invention belongs to the technical field of a joint for an airplane high-pressure guide pipe system, particularly relates to a corrugated pipe spherical joint and overcomes the problems of large weight, short service life and large leakage hidden danger of the existing metal corrugated expansion joint and the poor manufacturing manufacturability of the high-pressure guide pipe system. The corrugated pipe spherical joint comprises a corrugated pipe; two ends of the corrugated pipe are welded and connected with the inner end of a left connection pipe and the inner end of a right connection pipe respectively; an outer support is connected and welded with the outer end of the left connection pipe; an inner support is connected and welded with the outer end of the right connection pipe; the outside surface of a wear-resistant ring is fixedly connected to one end of a spherical hinge ring; the inside surface of the wear-resistant ring is an inner spherical surface and forms a spherical rotary pair with the inner support; the other end of the spherical hinge ring is welded and connected with the outer support; a limiting support is sleeved outside the spherical hinge ring and is connected and welded with the inner support. The corrugated pipe spherical joint has the characteristics of light weight, small size and long service life, so the leakage hidden danger of a pipeline is reduced, the reliability and maintainability are improved, the practicability is better, and the corrugated pipe spherical joint is easy for popularization and application and has larger practical value.

Description

technical field [0001] The invention belongs to the technical field of joints used in aircraft high-pressure conduit systems, in particular to a bellows type ball joint. Background technique [0002] In the aircraft high-pressure conduit system, it is necessary to use a compensator to compensate the stress and displacement caused by temperature changes, installation errors and mechanical vibrations to ensure the reliability and safety of the high-pressure conduit system. The traditional corrugated pipeline compensator (metal corrugated expansion joint) is applied on high-pressure conduits, and there are mainly the following problems: [0003] ① There are many joints between flanges and quick-release clamps, and there are hidden dangers of leakage; [0004] ② The connection joints and traditional metal corrugated expansion joints are heavy; [0005] ③ The service life is low and cannot be the same as the aircraft, which increases the repair and maintenance costs of the airc...
