Abstract
The utility model relates to a multi-nozzle fuel manifold for an aircraft engine. The multi-nozzle fuel manifold consists of metal connecting piece nuts, metal connecting piece nipples, metal connecting piece sleeves, stainless steel wire braided layers and a plurality of sections of polytetrafluoroethylene inner pipes, wherein the number of the polytetrafluoroethylene inner pipes depends on nozzles of the engine; each polytetrafluoroethylene inner pipe has a hollow tubular structure; the outer walls of the polytetrafluoroethylene inner pipes are wrapped with the stainless steel wire braided layers; the inner walls of the two ends of the polytetrafluoroethylene inner pipes are inserted into the metal connecting piece nipples respectively; the metal connecting piece sleeves are sleeved at the two ends of the polytetrafluoroethylene inner pipes wrapped with the stainless steel wire braided layers; the metal connecting piece nuts are connected with the metal connecting piece nipples. According to the multi-nozzle fuel manifold, the number of the nipples of an obtained product is consistent with that of the nozzles of the engine, so that aviation kerosene can be provided for each nozzle.
Description
Technical field
The utility model relates to a kind of aeroengine multi-nozzle fuel manifold.
Background technique
Steel wire reinforced polytetrafluoroethylspiral hose has high-low temperature resistant, corrosion-resistant, ageing-resistant, lightweight, the life-span long, absorb the features such as vibration, conventionally form by one section of steel wire reinforced polytetrafluoroethylspiral flexible pipe and at two ends assembling metal link, be mainly used in the transmission of medium as a kind of flexible conduit, use in systems such as all kinds of aviation aircraft hydraulic pressure, fuel oil, lubricating oil, cold air, alcohol at present.
In recent years, along with the develop rapidly of China's Aviation Industry, particularly aeroengine field, also more and more wider to the application of polytetrafluoroethylhose hose assembly.Different from traditional polytetrafluoroethylhose hose assembly structure, due to the nozzle of motor more (conventionally at 7～14), therefore, need on teflon hose, increase the ozzle suitable with nozzle quantity and just can be embodied as each nozzle aviation kerosine is provided.
Summary of the invention
The purpose of this utility model is to provide a kind of aeroengine multi-nozzle fuel manifold.
A kind of aeroengine multi-nozzle fuel manifold the utility model proposes, by metal connecting piece nut 1, metal connecting piece ozzle 2, metal connecting piece sleeve 3, Stainless Steel Wire braid 4 and teflon inner tube 5 form, wherein: teflon inner tube 5 has some sections, quantity is depending on engine nozzle, every section is the hollow tubular structure in middle part, outer wall is coated with Stainless Steel Wire braid 4, two ends inwall inserts respectively metal connecting piece ozzle 2, metal connecting piece sleeve 3 is placed on teflon inner tube 5 two ends that are coated with Stainless Steel Wire braid 4, metal connecting piece nut 1 is connected with metal connecting piece ozzle 2.
In the utility model, described metal connecting piece ozzle 2 in straight-through, two-way, threeway or four-way structure any.
In the utility model, teflon inner tube 5 internal diameters are φ 4mm to φ 16mm.
In the utility model, metal connecting piece ozzle 2 is several, and it is definite that quantity is looked engine nozzle, is generally 7～14.
The beneficial effects of the utility model are: the utility model assembles respectively multiple metal connecting piece ozzles by multistage through the teflon inner tube of braided steel wire and forms, the number of nozzles that guarantees products obtained therefrom is consistent with engine nozzle, and being embodied as each nozzle provides aviation kerosine.
Accompanying drawing explanation
Fig. 1 is structural diagrams of the present utility model.
Fig. 2 is design sketch of the present utility model.
Number in the figure: 1 is metal connecting piece nut, 2 is metal connecting piece ozzle, and 3 is metal connecting piece sleeve, and 4 is Stainless Steel Wire braid, and 5 is teflon inner tube.
Embodiment
1 further illustrate the utility model by reference to the accompanying drawings below by embodiment.
As shown in Figure 1, this aeroengine is made up of metal connecting piece nut 1, metal connecting piece ozzle 2, metal connecting piece sleeve 3, Stainless Steel Wire braid 4 and teflon inner tube 5 with multi-nozzle fuel manifold.Multistage teflon inner tube 5(quantity is looked engine nozzle and is determined) be the hollow tubular structure in middle part, teflon inner tube 5 outer walls are coated with Stainless Steel Wire braid 4, multiple metal connecting piece ozzle 2(are straight-through, two-way, threeway or four-way, quantity is determined depending on engine nozzle) insert respectively teflon inner tube 5 two ends inwalls, metal connecting piece sleeve 3 is placed on teflon inner tube 5 two ends that are coated with Stainless Steel Wire braid 4, and metal connecting piece nut 1 is connected with metal connecting piece ozzle 2.Obtain the fuel manifold that number of nozzles is consistent with engine nozzle quantity, being embodied as each nozzle provides aviation kerosine.
