Abstract
Provided is a double-ball corner sealing structure for traversing a casing, comprising a casing mounting seat, a first ball cup seat, a sealing pad, a pipe joint, a first bolt, a double ball cup leading pipe, a second ball cup seat, a piston ring, a sleeve, a second bolt, and inner casing mounting seat. The casing mounting seat is connected to the casing through welding or riveting. The first ball cup seat, the sealing pad and the pipe joint are fixed to the casing mounting seat through bolts. The first ball cup seat, the second ball cup seat and the double ball cup leading pipe are integrated into one piece. The first ball cup seat and the second ball cup seat can freely rotate in any directions within a space allowed with respect to the double ball cup leading pipe. The piston ring is disposed on the second ball cup seat and is in a clearance fit with the sleeve. The sleeve is fixed to the inner casing mounting seat through the second bolt. The double-ball corner sealing structure for traversing a casing is advantageous in that the corner sealing structure is suitable for pipes whose diameters range from Phi18 to Phi36; the assembling between the casing and the pipeline is improved; the capability of installation compensation and thermal expansion compensation can be possessed; installation stress force of the pipeline is reduced and maintainability of the pipeline is raised.
Description
Technical field
The present invention relates to aeroengine sealing configuration field, a kind of two balls angle sealing configuration 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 (perhaps independent sleeve).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 two balls angle sealing configuration 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.
Summary of the invention
The objective of the invention is in order to improve the assembling of casing, avoid scratching, colliding pipeline, the spy provides a kind of two balls angle sealing configuration that is used to pass casing.
A kind of two balls angle sealing configuration that is used to pass casing is characterized in that: include casing fitting seat 1, ball cup 1, sealing gasket 3, pipe joint 4, bolt 1, two bulb conduit 6, ball cup 27, piston ring 8, sleeve 9, bolt 2 10, interior casing fitting seat 11;
Wherein: casing fitting seat 1 welds or is riveted on the casing; Ball cup 1, sealing gasket 3, pipe joint 4 are fixed on the casing fitting seat 1 through 3 bolts 1; Ball cup 1, ball cup 27 are assembled into one with two bulb conduits 6, and ball cup 1, ball cup 27 can freely rotate in all directions in the space range that allows with respect to two bulb conduits 6; Piston ring 8 is installed on the ball cup 27, with sleeve 9 Spielpassung, in sleeve 9 is fixed on through 4 or 6 bolts 2 10 on the casing fitting seat 11.
Described ball cup 1, two bulb conduit 6, ball cup 27 are formed dual hinge structure.
Sealing gasket 3 between described ball cup 1 and the casing fitting seat 1 is asbestos packing or soft copper pad.
0.5 ± the 0.1mm that cracks on the described piston ring 8 is with ball cup 1, ball cup 27 assemblings; The thickness of piston ring 8 is 1.88 ~ 2mm, cooperates with the end clearance of ball cup 27 upper grooves; The 180 ° of installations in position of cracking of two piston rings 8 are sealed and matched with sleeve 9.
Advantage of the present invention: the two balls angle sealing configuration that is used to pass casing of the present invention; Be applicable to the occasion of (diameter is φ 18 ~ φ 36); After accomplishing the casing assembling; The pipeline that passes casing can be installed, improve the assembling of casing and pipeline, having cancelled casing is the requirement for restriction of opposite opened structure.Pipeline adopts dual hinge structure in the casing, has the compensation of installation and temperature compensation ability, has reduced the Installation Stress of pipeline.Two packing flanges are installed on ball cup, have been realized the sealing at interior casing fitting seat place; Increase sealing gasket between ball cup and the casing fitting seat, improved the sealing of casing position of opening.On dual hinge structure, piston ring is installed before the pipeline assembling, 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.
