Abstract
The invention provides a rigid connection structure of a pipeline penetrating through an engine box. The rigid connection structure of the pipeline penetrating through the engine box is characterized by comprising an engine box, an engine box installation seat, an outlet pipe sleeve, bolts, a long thread external cone connector, a locking barrel, an additional nut, a flat pipe nozzle and a conduit, wherein the engine box installation seat is connected on the engine box in a welded mode or in a riveting mode, the outlet pipe sleeve is fixed on the engine box installation seat through the bolts, a floating sleeve is in circumferential direction locking small clearance fit with the long thread external cone connector, the long thread external cone connector is connected with the locking barrel in a threaded mode, the additional nut, the flat pipe nozzle and the conduit are welded into a whole, and after the engine box is assembled, assembling of the pipeline is finished. The rigid connection structure of the pipeline penetrating through the engine box has the advantages of being simple in structure, less in the number of parts, reliable in working and capable of guaranteeing accurate assembling of the pipeline inside the engine box. The upper end face and the lower end face of the outlet pipe sleeve are matched tightly, so that sealing of an opening hole of the engine box can be guaranteed. No small parts need installing independently during the assembling of the pipeline, so that hidden danger caused by the parts falling into a duct of an engine from hole seats of the engine box can be effectively avoided, and maintainability of the pipeline is improved.
Description
Technical field
The present invention relates to the aeroengine field, particularly a kind of pipeline (diameter is φ 10 ~ φ 16) pipeline rigid connection structure that passes casing.
Background technique
Pass 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 adopts integral type to pass the sealing configuration of casing at the pipeline of φ 8 ~ φ 36 more, and namely in casing, the pipeline upper connection is exposed at outside casing, seals and the cold conditions angle compensation by socket arrangement between pipeline and casing.
Laid spatial constraints owing to stretching out the casing socket, adopt bend pipe structure being reduced to the casing height more, so when condition based maintenance need to decompose minute half casing, pull down and need to decompose a large amount of structures and could realize for passing the casing pipeline, workload is larger.
For this reason, on the tubular basis that possesses the compensation of installing and temperature compensation ability of pipeline self, need a kind of pipeline rigid connection structure that passes casing of design, minimizing link quantity in casing, realize installation and the seal request of casing, pipeline, improve the pipeline assembling and the maintainability that pass casing.
Summary of the invention
To the objective of the invention is the pipeline assembling and the maintainability that pass casing in order improving, a kind of pipeline rigid connection structure that passes casing to be provided especially.
The invention provides a kind of pipeline rigid connection structure that passes casing, it is characterized in that: include casing 1, casing fitting seat 2, fairlead sleeve 3, bolt 4, long screw thread outside cone joint 5, locking swivel nut 6, caption nut 7, flat ozzle 8, conduit 9;
Wherein: casing fitting seat 2 welds or is riveted on casing 1, fairlead sleeve 3 is fixed on casing fitting seat 2 by bolt 4, tripping sleeve 3 and the long screw thread outside cone joint 5 little Spielpassung of circumferential stop, long screw thread outside cone joint 5 is threaded with locking swivel nut 6, caption nut 7, flat ozzle 8, conduit 9 are integrally welded, complete this pipeline assembling after the casing assembling.
On described fairlead sleeve 3 and the interior pipeline of casing 1, long screw thread outside cone joint 5 adopts the little Spielpassung of circumferential stop.
Described fairlead sleeve 34 of employings or 6 bolts 4 are fixed on casing fitting seat 2.
Described locking swivel nut 6 adopts 4 or 6 round platform spanners with groove, is used for compressing long screw thread outside cone joint 5, realizes being rigidly connected and the sealing of casing tapping.
The described pipeline rigid connection structure that passes casing, being rigidly connected of its fairlead sleeve 3, long screw thread outside cone joint 5, locking swivel nut 6, integral body applies the installation countertorque when casing outer tube road is installed.
Advantage of the present invention:
Rely under self tubular prerequisite of carrying out the cold and hot state compensation based on pipeline in casing, the rigid connection structure that originally passes the casing pipeline is simple, and number of spare parts is few, reliable operation.Fairlead sleeve and casing are for being rigidly connected, and it designs with the little Spielpassung of the circumferential stop of long screw thread outside cone joint, guarantees the accurate assembly of pipeline in casing.The locking swivel nut is threaded with long screw thread outside cone joint, and the upper and lower end face of fairlead sleeve is coordinated closely, has guaranteed the sealing of casing tapping.Be rigidly connected between the three, installing for the outer pipeline of casing provides countertorque.Owing to there is no the independent finding of installing when pipeline assembles, effectively avoided part to fall into hidden danger in the motor duct by casing hole seat, improved the maintenance of pipeline.
