Abstract
The invention discloses a seal structure of a hyperbolic curve spherical surface inner cone pipeline. The seal structure is characterized by comprising an external cone connector, an internal cone connector, an additional nut, a guiding pipe and a guiding pipe; wherein the external cone connector is in matched connection with the internal cone connector, the other end of the external cone connector is welded with one guiding pipe and the other end of the internal cone connector is welded with the other guiding pipe; the additional nut is arranged at one end of the internal cone connector in the pipeline and is screwed tightly and matched with an external thread of the external cone connector through an internal thread, so that the seal structure of an internal cone hyperbolic curve spherical surface pipeline is integrally formed. The invention has the advantage that the seal structure of the hyperbolic curve spherical surface inner cone pipeline is designed for purposes of controlling weight of the seal structure of a pipeline of an aeroengine and guaranteeing tightness of the structure at the same time. The seal structure has the advantages of lighter weight and better tightness. When the pipeline works, probability of oil leakage of the seal structure is low and maintainability is good; and a pipeline connector can still be reliably sealed even under a circumstance that a certain angle exists during an installation process; and an internal cone surface adopts a spherical surface design, and the seal structure has better repairability.
