Abstract
An eccentric spherical surface outer taper pipeline sealing structure used in an aero-engine is characterized by comprising an external taper joint, a flat pipe nozzle, an additional nut, a guiding pipe, and another guiding pipe, wherein the external taper joint is connected with the flat pipe nozzle; the other end of the external taper joint is welded with one guiding pipe; the other end of the flat pipe nozzle is welded with the other guiding pipe; the additional nut is arranged at one end of the flat pipe nozzle in a pipeline; and the additional nut is tightly screwed and matched with external threads of the external taper joint through internal threads. The eccentric spherical surface outer taper pipeline sealing structure has the advantages that the eccentric spherical surface structure is adopted so that the weight is relatively low; the linear sealing structure form is adopted so that the sealing property is relatively good; a sealing line formed by the eccentric spherical surface and the inner taper surface under the working environment is low in probability of oil leakage and relatively good in maintainability; the pipeline joint can still be reliably sealed even under a circumstance that a certain angle exists during the mounting process; and at the same time, the sealing structure adopts the spherical surface design so that the sealing structure has a relatively good repairability.
Description
Technical field
The utility model relates to aeroengine field, particularly a kind of for aeroengine eccentric spherical outer cone pipe sealing structure.
Background technique
At present, the development trend of advanced aero engine is to improve constantly thrust weight ratio both at home and abroad, require part reliability, maintainability higher simultaneously, and improve motor thrust weight ratio the most effectively one of means be component meeting outside function and other require, reduce to greatest extent weight.
Aeroengine pipeline is for the transmission of fluid, gas, and the weight of pipeline, when controlling, guarantee the sealability of pipeline.Main spherical linear sealing structure, the cone match profile sealing configuration of adopting.Semi-sphere type linear sealing sealing structure good reliability, conical surface sealing structure oil spill rate is low more than 70% relatively, and after its sphere is impaired, the reparation of sphere is good, but weight is heavier; The surface seal structure of cone match is lightweight, but sealing effect is poor, after the conical surface is impaired, is difficult to repair.
For above present situation, need a kind of eccentric spherical outer cone Novel pipeline sealing configuration of design, when alleviating pipe weight, guarantee the sealing reliability of pipeline, improve the assembling of pipeline, reparation property.
Model utility content
The purpose of this utility model is when alleviating pipe weight, guarantees the sealing reliability of pipeline, improves the assembling of pipeline, reparation property, and it is a kind of for aeroengine eccentric spherical outer cone pipe sealing structure that spy provides.
It is a kind of for aeroengine eccentric spherical outer cone pipe sealing structure that the utility model provides, and it is characterized in that: comprise outside cone joint 1, flat ozzle 2, caption nut 3, the first conduit 4, the second conduit 5;
Wherein: outside cone joint 1 is connected with flat ozzle 2, outside cone joint 1 the other end and the first conduit 4 weld, flat ozzle 2 the other ends and the second conduit 5 weld; Caption nut 3 is flat ozzle 2 one end in pipeline 4, by internal thread, are tightened and coordinate with outside cone joint 1 outside thread, play the effect of external cone joint 1 and flat ozzle 2 fixing seals.
Described outside cone joint 1 fitting surface adopts eccentric sphere male cone (strobilus masculinus), and surface Machining has outside thread.
Described flat ozzle 2 is wimble structure in 74 °; Eccentric sphere male cone (strobilus masculinus) in outside cone joint 1 coordinates formation potted line with 74 ° of inner cones in flat ozzle 2, play the seal action to two connecting pipelines.
Male cone (strobilus masculinus), by adopting eccentric sphere structure, reduces part external diameter, alleviates pts wt.
While there is bias in outside cone joint 1 and flat ozzle 2 assembly processes, can effective sealing.
Aeroengine eccentric spherical outer cone pipe sealing structure, when having controlled the weight of seal structural part, has guaranteed sealing, reliability and the assembling of sealing configuration.
Advantage of the present utility model:
Described in the utility model for aeroengine eccentric spherical outer cone pipe sealing structure, adopt eccentric spherical structure, weight is lighter, adopts the structural type of linear sealing, and sealing is better; The potted line that eccentric spherical and inner conical surface form is under working environment, and the probability that leakage of oil occurs is low, has good maintainability; The in the situation that pipe joint being deposited several angle in installation process, still can reliable sealing; In sealing configuration, adopt sphere design simultaneously, there is good recoverability.
