Abstract
An abnormal-shaped nut type floating sealing structure used for penetrating through a cartridge receiver comprises a cartridge receiver installation seat, a floating sleeve, an installation seat press plate, a bolt, a caulking ring, a flat pipe orifice, an abnormal-shaped externally-added nut, and a connector, wherein the cartridge receiver installation seat is welded or riveted on the cartridge receiver; the installation seat press plate is fixed on the cartridge receiver installation seat through the bolt; the floating sleeve is in clearance fit with the cartridge receiver installation seat and the installation seat press plate and can freely move in the circumferential direction; and the caulking ring is arranged on the abnormal-shaped externally-added nut and is in small clearance fit with the floating sleeve. The abnormal-shaped nut type floating sealing structure has the advantages of improving assembling performance of the cartridge receiver and a pipeline, removing the restriction requirement of the cartridge receiver for an open structure, having capacities of installation compensation and heat expansion compensation due to the floating sleeve arranged on the cartridge receiver installation seat, and reducing installing stress of the pipeline. The abnormal-shaped nut type floating sealing structure is a pipeline sealing structure penetrating through the cartridge receiver on an aero-engine, improves product performance, improves the assembling performance and sealing performance of the cartridge receiver and the pipeline, and reduces the installing stress of the pipeline.
Description
Technical field
The present invention relates to aerial engine sealing structure field, a kind of abnormity nut formula floating sealing structure be used to passing casing is provided especially.
Background technique
Pass the pipeline of casing on the conventional engines, different according to 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 the pipeline upper connection is exposed at outside the casing in the casing, adopts minute half a formula floating ring to cooperate with casing fitting seat endoporus.This sealing configuration is fixing simply, sealing is reliable, is the opposite opened structure but require casing.Often there are many disalignments to pass casing to the pipeline of, angular position on the motor, therefore when casing assembled, the casing mounting hole need to be aimed at each pipeline position, has not only reduced the assembling of casing, and easily scratch, the collision pipeline, increased the assembling work difficulty.
For this reason, need a kind of abnormity nut formula floating sealing structure be used to passing casing of design, can have the compensation of installation and temperature compensation ability, realize the installation requirement of pipeline and the seal request of casing, can be applicable to simultaneously whole and minute half formula casing.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of abnormity nut formula floating sealing structure be used to passing casing is provided especially.
A kind of abnormity nut formula floating sealing structure be used to passing casing is characterized in that: include casing fitting seat 1, tripping sleeve 2, fitting seat pressing plate 3, bolt 4, piston ring 5, flat ozzle 6, special-shaped caption nut 7, outside cone joint 8.
Fitting seat pressing plate 3 is fixed on can adopt 4 or 6 bolts 4 on the casing fitting seat 1.
Abnormity nut formula floating sealing structure be used to passing casing provided by the invention, the inside and outside conduit tube component of its casing can adopt in 74 °/conical surface seal form, sphere/60 ° inner cone seal form etc.
Abnormity nut formula floating sealing structure be used to passing casing provided by the invention, its special-shaped caption nut 7 adopts hexagonal or round platform spanner structure and two side chain silk holes.
Abnormity nut formula floating sealing structure be used to passing casing provided by the invention, 0.5 ± 0.1 mm that cracks on its piston ring 5 is with special-shaped caption nut 7 assemblings; The thickness of piston ring 5 is 2 (0 ~-0.12) mm, cooperates with the end clearance of special-shaped caption nut upper groove; The 180 ° of installations in position of cracking of two piston rings are with tripping sleeve 2 fitted seal.
Advantage of the present invention:
The pipeline off position that passes casing is lower than the casing internal surface, by lengthening special-shaped caption nut, has improved the assembling of casing and pipeline, and having cancelled casing is the requirement for restriction of opposite opened structure.On the casing fitting seat tripping sleeve is installed, has the compensation of installation and temperature compensation ability, reduced the installation stress of pipeline.At special-shaped caption nut two packing flanges are installed, have been improved the sealing of casing position of opening.
Before the pipeline assembling piston ring has been installed on special-shaped caption nut, has effectively been avoided individual part to fall into hidden danger in the motor duct by casing hole seat, improved the maintenance of pipeline.
