Abstract
A sleeve-tooth-shaped floating sealing structure penetrating a casing is characterized by comprising the casing, casing mounts, transfer pipe sleeves, bolts, an external cone connector, a guide pipe, a ball joint housing, a ball joint, a captive nut, a flat nozzle and a guide pipe. The external cone connector and the guide pipe are integrated to be a guide pipe assembly inside the casing; the captive nut, the flat nozzle and the guide pipe are integrated by welding to be a guide pipe assembly outside the casing; the casing mounts are connected on the casing by welding or riveting; the transfer pipe sleeves are fixed on the casing mounts through bolts ,and closed up through the ball joint housing to be integrated with the ball joint; the ball joint housing can freely rotate corresponding to the ball joint in all directions within an allowed spacial range; and the ball joint is welded on the guide pipe. The sleeve-tooth-shaped floating sealing structure penetrating the casing has the advantages that the sealing structure is mainly designed for pipelines penetrating the casing on aero-engines, and the sealing structure with diameter of phi 6-phi 12 improves product performance, improves assemblability and tightness of the casing and the pipelines, and reduces assembly stress of the pipelines.
Description
Technical field
The present invention relates to aerial engine sealing construction applications, specifically provide a kind of for the cover profile of tooth floating sealing structure through casing.
Background technique
Through the pipeline of casing on conventional engines, according to the difference of its diameter and transmission medium, the sealing configuration of employing is also different.General diameter passes the sealing configuration of casing in pipeline many employings integral type of φ 6 ~ φ 12, and namely in casing, pipeline upper connection is exposed at outside casing, adopts a point half formula floating ring to coordinate with casing fitting seat endoporus (or separate ferrule).This sealing configuration is fixing simply, sealing is reliable, but requires that casing is opposite opened structure.Often motor there are many pipelines that are axially different, angular position to pass casing, therefore, when casing assembles, casing mounting hole needs to aim at each conduit positions, not only reduces the assembling of casing, and easily scratch, collision pipeline, add assembling work difficulty.
For this reason, need design a kind of for the cover profile of tooth floating sealing structure through casing, can have and compensation and temperature compensation ability are installed, realize the installation requirement of pipeline and the seal request of casing, an overall and point half formula casing can be applicable to simultaneously.
Summary of the invention
The object of the invention is to reduce assembling difficulty, having and installing compensation and temperature compensation ability, spy provides a kind of for the cover profile of tooth floating sealing structure through casing.
The invention provides a kind of for the cover profile of tooth floating sealing structure through casing, it is characterized in that: include casing 1, casing fitting seat 2, fairlead sleeve 3, bolt 4, outside cone joint 5, conduit 6, ball cup 7, bulb 8, caption nut 9, flat ozzle 10, conduit 11;
Wherein: outside cone joint 5, conduit 6 are integrally welded, be casing inner conduit assembly; Caption nut 9, flat ozzle 10, conduit 11 are integrally welded, for casing outer duct assembly, casing fitting seat 2 welds or is riveted on casing 1, fairlead sleeve 3 is fixed on casing fitting seat 2 by 6 or 8 bolts 4, closed up by ball cup 7, make itself and bulb 8 be assembled into one, ball cup 7 freely can rotate in all directions in the space range allowed relative to bulb 8, and bulb 8 is welded on conduit 6.
Described outside cone joint 5 tightens countertorque spanner structure.
Described outside cone joint 5 is lower than casing main duct surface.
Fairlead sleeve 3, ball cup 7, bulb 8 form special-shaped double hinge structure.
The inside and outside conduit tube component of described casing adopts in 74 °/conical surface seal form or sphere/60 ° inner cone seal form.
Its described outside cone joint 5 adopts the round platform spanner of 4 or 6 grooves.
The internal surface that described fairlead sleeve 3 coordinates with ball cup 7, adopts electrical spark alloyage graphitization coating.
Advantage of the present invention: be applied to the pipeline through casing, diameter is in φ 6 ~ φ 12 sealing configuration, through the pipeline off position of casing lower than casing duct internal surface, in casing, pipeline adopts the round platform spanner structure of band groove, improve the assembling of casing and pipeline, eliminate the restriction requirement that casing is opposite opened structure.In casing, pipeline adopts special-shaped double hinge structure, has to install to compensate and temperature compensation ability, reduces the mount stress of pipeline.Fairlead sleeve graphitization coating, not only greatly reduces frictional force, and reduces the degree of wear of sleeve, improve the sealing of casing position of opening.Through the pipeline of casing when assembling due to the independent finding installed, effectively prevent part and fallen into hidden danger in motor duct by casing hole seat, improve the maintenance of pipeline.
