Abstract
An abnormity nut type floating seal structure for penetrating through a casing comprises an casing installing base, a floating sleeve, an installing base pressing plate, a bolt, a piston ring, a flat nozzle, an external abnormity nut and a connector. The casing installing base is welded or riveted on the casing, the installing base pressing plate is fixed on the casing installing base through the bolt, the floating sleeve is in clearance fit with the casing installing base and the installing base pressing plate, the periphery of the floating sleeve can move freely, and the piston ring is installed on the external abnormity nut and in small clearance fit with the floating sleeve. The abnormity nut type floating seal structure for penetrating through the casing has the advantages that assembling performance of the casing and a pipeline is improved, and the casing is not required to be in a split structure. The floating sleeve is arranged on the casing installing base and has installing compensation capacity and thermal expansion compensation capacity, and installing stress of the pipeline is reduced. The irregular-shaped nut floating sealing structure for penetrating through the casing is mainly aims at an aircraft engine, improves product performance, assembling performance and sealing performance of the casing and the pipeline, and reduces installing stress of the pipeline.
Description
Technical field
The utility model relates to aeroengine sealing configuration field, and a kind of abnormity nut formula floating sealing structure that is used to pass 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 promptly the pipeline upper connection is exposed at outside the casing in the casing, adopts and divides half 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 on the motor to the pipeline of, angular position; Therefore when casing assembled, the casing mounting hole need be aimed at each pipeline position, has not only reduced the assembling of casing; And be prone to scratch, collide pipeline, increased the assembling work difficulty.
For this reason, need to design a kind of abnormity nut formula floating sealing structure that is used to pass casing, can have installation compensation and temperature compensation ability, realize the installation requirement of pipeline and the seal request of casing, can be applicable to whole simultaneously and branch half formula casing.
The model utility content
The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of abnormity nut formula floating sealing structure that is used to pass casing is provided especially.
The objective of the invention is to overcome the deficiency of existing technology, a kind of abnormity nut formula floating sealing structure that is used to pass casing is provided especially.
A kind of abnormity nut formula floating sealing structure that is used to pass casing is characterized in that: the described abnormity nut formula floating sealing structure that is used to pass casing includes 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, joint 8;
Casing fitting seat 1 welds or is riveted on the casing; Fitting seat pressing plate 3 is fixed on the casing fitting seat 1 through 4 or 6 bolts 4; Tripping sleeve 2 and casing fitting seat 1, fitting seat pressing plate 3 Spielpassung; Circumferentially can move freely 1 ~ 3mm, piston ring 5 is installed on the special-shaped caption nut 7, with tripping sleeve 2 little Spielpassung.
Spanner structure and lock silk hole are arranged on the described special-shaped caption nut 7.
Flat ozzle 6, special-shaped caption nut 7, joint 8 connect, and realize that the inside and outside pipeline of casing connects and sealing.
The mounting point of described outside cone joint 8 is lower than casing main duct surface.The abnormity nut formula floating sealing structure that is used to pass 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; Piston ring 5 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.
The advantage of the utility model:
The pipeline off position that passes casing is lower than the casing internal surface, through the special-shaped caption nut that extends, 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.Two packing flanges are installed on special-shaped caption nut, 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 the hidden danger in the motor duct, improved the maintenance of pipeline through casing hole seat.
