Abstract
The utility model relates to a connecting structure of a line sealing pipeline. The connecting structure is characterized by comprising an eccentric spherical surface, an inner conical surface, a size SRA, a size RB and a size C, wherein the eccentric spherical surface and the inner conical surface are matched to integrally constitute the connecting structure of the line sealing pipeline, and a basic structure of the eccentric spherical surface is determined by the size SRA, the size RB and the size C. The connecting structure of the line sealing pipeline disclosed by the utility model has the advantage that the connecting structure of the line sealing pipeline is designed for controlling the weight of the pipeline sealing structure of an aircraft engine and simultaneously guaranteeing the sealing effect of the structure. The structure of the eccentric spherical surface is used, the weight is lower, a line sealing structure is used, and the sealing performance is good; the oil leak probability of the sealing line formed by the eccentric spherical surface and the inner conical surface under the work environment is low, and the maintainability is good; when an eccentric angle exists in the matching of the eccentric spherical surface and the inner conical surface, the structure can still be reliably sealed; and at the same time, a spherical surface design is used in the sealing structure, so that the reparability is good.
Description
Technical field
The present invention relates to the aeroengine field, a kind of linear sealing pipeline jointing construction is provided especially.
Background technique
Domestic and international advanced development of Aeroengines trend is to improve constantly thrust weight ratio, when guaranteeing part reliability, maintainability, reduces the weight of component.At present, the aeroengine caliber mainly adopts the surface seal structure form of semi-sphere type linear sealing structure and cone match less than the pipeline of φ 20.The pluses and minuses contrast: semi-sphere type linear sealing sealing structure good reliability, conical surface seal structure oil spill rate hangs down more than 70% relatively, and after its sphere was impaired, the reparation property of sphere was good, but weight is heavier; The surface seal structure of cone match is in light weight, but sealing effect is relatively poor, after the conical surface is impaired, is difficult to repair.
To above present situation, need a kind of linear sealing pipeline jointing construction of design, when alleviating structure weight, sealing reliability that guarantee and recoverability.
Adopt brand-new fit form in the linear sealing structure, reduce the overall dimensions of Sealing,, guaranteed the sealing effect of sealing configuration effectively reducing pipeline weight simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing line seal structure, a kind of linear sealing pipeline jointing construction is provided especially.
The invention provides a kind of linear sealing pipeline jointing construction, it is characterized in that: comprise eccentric sphere 1, inner conical surface 2, size SRA3, size RB4, size C5.
In the linear sealing structure, eccentric sphere 1 cooperates with inner conical surface 2, whole formation linear sealing pipeline jointing construction.
The basic structure of eccentric sphere 1 is confirmed through size SRA3, size RB4, size C5.Through control size RB4, size C5, reduce accessory size, alleviate Sealing weight, when in eccentric sphere 1 and inner conical surface 2 engagement process, having off-centre, structure can effectively seal, and is applicable to being tightly connected of various caliber pipelines; Through regulating the eccentric distance of size RB4 control outer cone sphere; Through regulating the axial position in the size C5 control eccentric sphere center of circle, through regulating the radius of size SRA3 control eccentric sphere.Optimize and revise size SRA3, size RB4, size C5; Reduce the overall dimensions of eccentric sphere linear sealing structure; Confirm that simultaneously eccentric sphere 1 and inner conical surface 2 faying surfaces form the optimum position of potted line, realize that eccentric sphere 1 cooperates with inner conical surface 2, guarantee effective sealing of linear sealing structure.
Described size SRA3, size RB4, two groups of couplings below the size C5 choosing, unit is a millimeter, and first group is: SRA is 7.75, and RB is 1.83, and C is 5.63; Second group is: SRA is 8.75, and RB is 1.73, and C is 6.14.
Novel sealing structure adopts the linear sealing form, when there is certain drift angle with inner conical surface 2 in eccentric sphere 1 in cooperation, still can between eccentric sphere and fitting surface, form potted line together, and structure is effectively sealed.
Advantage of the present invention: be control aeroengine line seal structure weight, guarantee the sealing effect of structure simultaneously, design a kind of linear sealing pipeline jointing construction.This structure adopts eccentric spheric structure, and weight is lighter, adopts the structural type of linear sealing, and sealing is better; The potted line that eccentric sphere and inner conical surface form is under working environment, and the probability that leakage of oil takes place is low, has maintainability preferably; When there was eccentric angle in eccentric sphere when cooperating with inner conical surface, structure still can reliable sealing; Adopt the sphere design simultaneously in the sealing configuration, have recoverability preferably.
