Abstract
The utility model discloses a protection structure used for a pipeline joint of a high-temperature region of an aircraft engine. The protection structure used for the pipeline joint of the high-temperature region of the aircraft engine is characterized by comprising a hood, a fixing plate, a bolt, a nut and the pipeline joint, wherein the hood covers the pipeline joint; the hood is of a semi-cylindrical surface structure and is axially provided with a square groove, through which the pipeline passes, a planar structure is arranged on one end of the hood, a through hole is arranged in the planar structure, the bolt and the nut penetrate through the through hole of the planar structure so as to install the hood on the fixing plate, and the fixing plate is fixedly connected to the pipeline joint. The protection structure has the advantages of simple structure, convenience for production, convenience for assembly and disassembly, good maintainability, and capability of effectively protecting the pipeline joint of the high-temperature region of the aircraft engine, effectively preventing an oil product, which is leaked from the joint, from sputtering to the outer wall of an engine case, and improving safety of the engine.
Description
Technical field
The utility model relates to aeroengine safety protection field, particularly a kind of aeroengine high-temperature zone pipe joint safeguard structure.
