[0002] For many years, it has been widely used in aviation and other weapons and equipment. However, with the continuous development of my country's aviation equipment, various technical indicators of military and civil aircraft are also constantly improving and improving. Commonly used bellows made of ordinary stainless steel are mainly used. The single structure pipeline compensator is far from satisfying the installed application

Embodiment Construction
[0013] The double inner hinged bellows compensator is composed of a bellows assembly and a hinged mechanism assembly.
[0014] 1. Bellows assembly: composed of bellows, male joints, female joints, joint sleeves and reinforcing rings,
[0015] A corrugated pipe, joint sleeves at both ends, two reinforcing rings, and male and female joint parts are connected by electron beam welding to form a corrugated pipe assembly.
[0016] 2. Hinged mechanism components: including hinged inner sleeve, hinged looper, hinged outer sleeve and inner sleeve,
[0017] The hinged inner sleeve, hinged looper, and hinged outer sleeve are screwed into the hinged inner sleeve through the preset process gap in the inner diameter of the hinged outer sleeve to form a spherical revolving pair. The hinged outer cover is fixedly connected with the male joint.
[0018] The nozzles of the two ends of the bellows straight edge section form an external fit with the reinforcing ring, and form an internal fit wi...

The invention belongs to the technical field of pipeline compensators and particularly relates to a double-internal hinging type corrugated pipeline compensator, aiming at providing the pipeline compensator which can complete the functions of axial and radial compensation and has the functions of axial tension, compression limiting and radial swing limiting. The pipeline compensator comprises a corrugated pipe assembly and a hinging mechanism assembly, wherein the corrugated pipe assembly comprises a corrugated pipe, a convex joint, a concave joint and a joint sleeve, and the hinging mechanism comprises a hinging inner sleeve, a hinging movable sleeve, a hinging outer sleeve and an inner sleeve; the corrugated pipe assembly completes the sealing and flexible connecting compensation of the pipe; and the functions of axial tension, compression limiting and radial swing limiting are realized by the hinging mechanism. According to the double-internal hinging type corrugated pipeline compensator, the pipe compensator can complete the functions of axial and radial compensation and has the functions of axial tension, compression limiting and radial swing limiting.
Description
technical field [0001] The invention belongs to the technical field of pipeline compensators, and in particular relates to a double inner hinged corrugated pipeline compensator. Background technique [0002] For many years, it has been widely used in aviation and other weapons and equipment. However, with the continuous development of my country's aviation equipment, various technical indicators of military and civil aircraft are also constantly improving and improving. Commonly used bellows made of ordinary stainless steel are mainly used. The single-structure pipeline compensator composed of these components is far from satisfying the installed application. Therefore, it is imminent to develop a new pipeline compensator with high temperature resistance, high pressure resistance, strong vibration resistance, large compensation amount, long life and high reliability. Contents of the invention [0003] The purpose of the present invention is to provide a pipeline compensato...
