Abstract
Through a gas pipeline linkage structure for casing, it is characterized in that: comprise casing, casing fitting seat, floating ring, individual contacts, sealing gasket, joint, conduit, quick-release ring; Casing fitting seat welds or is riveted on casing, floating ring is arranged between individual contacts and casing fitting seat, realize casing tapping sealing and pipeline installation, temperature compensation, adopt between individual contacts with joint and be threaded, be equipped with sealing gasket between the two, individual contacts, joint adopt sealing gasket sealing, and adopt quick-release ring to be connected and fixed, joint, conduit are welded into pipeline in casing.Advantage of the present invention: the assembling that improve casing and pipeline.Utilizing the rigidity of large-diameter guide self, eliminating countertorque requirement when assembling casing outer tube road.Individual contacts designs, and reduces the inside and outside line connection diameter of casing, effectively reduces the opening diameter of casing, reduce the operating space of assembling, improves assembling maintainability.
Description
Technical field
The present invention relates to aeroengine pipeline linkage structure field, specifically provide a kind of gas pipeline linkage structure through casing, diameter is φ 30 ~ φ 50.
Background technique
Through the gas pipeline (diameter is at φ 30 ~ φ 50) of casing on conventional engines, in order to the seal request of the installation and casing tapping that meet the inside and outside pipeline of casing, the often more complicated of linkage structure design between pipeline, casing opening diameter is comparatively large, reduces the intensity of casing.The general linkage structure through casing, in casing, pipe joint is exposed at outside casing more, adopts point half formula floating ring and a casing fitting seat inner hole.This linkage structure is fixing simply, sealing is reliable, but increases the difficulty of casing assembling work.Often motor has the pipelines of many axially different, angular position through casing, therefore when casing assemble, casing mounting hole needs to aim at each conduit positions, not only reduces the assembling of casing, and easily scratches, collides pipeline.
For this reason, a kind of gas pipeline linkage structure through casing need be designed, can have to install and compensate and temperature compensation ability, realize the opening diameter of the connection of the inside and outside pipeline of casing, installation requirement and reduction casing, the assembling of raising casing.
Summary of the invention
The object of the invention is to compensate and temperature compensation ability to have to install, a kind of gas pipeline linkage structure through casing is provided especially.
The invention provides a kind of gas pipeline linkage structure through casing, it is characterized in that: comprise casing 1, casing fitting seat 2, floating ring 3, individual contacts 4, sealing gasket 1, joint 1, conduit 7, sealing gasket 28, joint 29, quick-release ring 10;
Casing fitting seat 2 welds or is riveted on casing 1, floating ring 3 is arranged between individual contacts 4 and casing fitting seat 2, realize casing tapping sealing and pipeline installation, temperature compensation, adopt between individual contacts 4 with joint 1 and be threaded, be equipped with sealing gasket 1 between the two, individual contacts 4, joint 29 adopt sealing gasket 28 to seal, and adopt quick-release ring 10 to be connected and fixed, joint 1, conduit 7 are welded into pipeline in casing.
Described individual contacts 4 upper end is quick-release ring linkage structure and hexagon wrench boss, and centre is floating ring draw-in groove, and lower end is outside thread plain adapter.
Its described joint 29 is with the seal groove of bulge loop of obturaging.
Sealing gasket 1 between described individual contacts 4 and joint 1, joint 29, sealing gasket 28 adopt soft copper pad, realize the inside and outside line seal of casing.
Advantage of the present invention:
Through the gas pipeline linkage structure of casing, improve the assembling of casing and pipeline.Utilizing the rigidity of large-diameter guide self, eliminating countertorque requirement when assembling casing outer tube road.Employing individual contacts designs, and reduces the inside and outside line connection diameter of casing, effectively reduces the opening diameter of casing.The outer pipeline of casing adopts quick-release ring to connect design, reduces the operating space of assembling, improves assembling maintainability.
