The application belongs to the technical field of pipeline connection structure design, and in particular relates to a pipeline connection structure, comprising: two fixed cylinders; Rotate relative to the fixed cylinder; the second rotating cylinder, one end of which is sleeved with one end of the other fixed cylinder, is in sealing contact with the fixed cylinder, and can rotate relative to the fixed cylinder, and the other end of the second rotating cylinder is bent with the other end of the first rotating cylinder The sleeve is in sealing contact with the first rotating cylinder and can slide relative to the first rotating cylinder; the first rotating cylinder is bent toward one end of the second rotating cylinder. In addition, it relates to a spherical convergent vector nozzle structure, comprising a fixed spherical shell, a movable spherical shell capable of deflecting relative to the fixed spherical shell, a hydraulic actuator connected to the movable spherical shell, and a hydraulic pump connected to the fixed spherical shell, In addition, it also includes: the above-mentioned pipeline connection structure, wherein one fixed cylinder is connected with the pump port of the hydraulic pump; the other fixed cylinder is connected with the hydraulic port of the hydraulic actuator.
Description
technical field [0001] The application belongs to the technical field of pipeline connection structure design, and in particular relates to a pipeline connection structure and a spherical convergent vector nozzle structure. Background technique [0002] The aero-engine spherical convergence vector nozzle is mainly composed of a fixed spherical shell and a moving spherical shell, in which the moving spherical shell can deflect relative to the fixed spherical shell to generate a vector pitch angle and achieve vector thrust. [0003] The spherical convergent vector nozzle adjusts the outlet area through the hydraulic actuator connected to the moving spherical shell, and the hydraulic actuator is driven by the hydraulic pump of the fixed spherical shell. Most of the pumps are connected by hard material pipes. This connection method has the following defects: [0004] 1), the assembly precision is high, and precise positioning is required; [0005] 2) When the moving spherical ...
