Abstract
The utility model relates to a fuel manifold, which comprises a pipe joint, a connection pipe and a fuel hose, wherein the connection pipe has a bulb arranged thereon, the radius of the bulb is10-35mm, and the fuel hose is sleeved on the connection pipe and is secured via a metal sleeve. By arranging the bulb on the connection pipe and sleeving the fuel hose over the connection pipe, the fuel hose can rotate around the bulb. The fuel manifold is easy for installation, better in connection reliability and longer in service lifetime. And, the fuel hose does not deform.
Description
Technical field
The utility model relates to a kind of oil pipe, is specifically related to a kind of fuel manifold of aeroengine.
Background technique
The flexible fuel manifold that adopts on the aeroengine, generally working out outer field teflon hose and metallic pipe coupling by the band steel wire withholds by metal sleeve and forms, its pipe joint can not rotate freely, when this non-rotatable fuel manifold assembles on the little small aero of external diameter, because of the spacing between the pipe joint on the fuel manifold very little, torsional deformation can appear between pipe joint and the flexible pipe, join strength reduces, and has grown service time oil impregnate, leakage of oil may occur even cause the flexible pipe release failure.
Summary of the invention
It is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, and assembling is good, and join strength is good, the fuel manifold that can rotate freely.
Fuel manifold of the present utility model comprises pipe joint, connecting tube and fuel hose, it is characterized in that: it is 10 that described connecting tube is provided with radius---35 millimeters bulb; Described fuel hose is enclosed within on the connecting tube, is tightened up by metal sleeve.
The connecting tube of fuel manifold of the present utility model is provided with bulb, and fuel hose is enclosed within on the connecting tube, and fuel hose can circumferentially rotate around bulb, and is easy for installation, and fuel hose is indeformable, and connection reliability is good, and the life-span is long.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, pipe joint, 2, bulb, 3, metal sleeve, 4, fuel hose, 5, connecting tube.
Embodiment
