Pipeline double-thread connection structure penetrating through cartridge receiver

Abstract

A pipeline double-thread connection structure penetrating through a cartridge receiver is characterized by comprising the cartridge receiver, a cartridge receiver installation seat, a leading out tube sleeve, a bolt, a floating ring, a sealing threaded sleeve, a double-thread external cone joint, a guide tube, an added nut, a flat tube opening and a guide pipe, wherein the external cone joint and the guide tube are welded into a whole to be as a cartridge receiver inner guide tube component; the added nut, the flat tube opening and the guide pipe are welded into whole to be a cartridge receiver outer guide tube component, the cartridge receiver installation seat is welded or riveted on the cartridge receiver, the leading out tube sleeve is fixed on the cartridge receiver installation seat through the bolt, and the floating ring is installed between the sealing threaded sleeve and the leading out tube sleeve. The pipeline double-thread connection structure penetrating through the cartridge receiver has the advantages that a bend pipe structure can still be adopted for a cartridge receiver outer pipeline to lower the arranged height of pipelines, and the assembling performance of the cartridge receiver and the pipelines is improved at the same time. The matching structure of the floating ring and the leading out tube sleeve is adopted for a cartridge receiver inner pipeline, the pipeline double-thread connection structure penetrating through the cartridge receiver has installation compensation and thermal expansion compensation capacities, installation stress of the pipelines is reduced, sealing performance of the holing position of the cartridge receiver is improved, and maintenance performance of the pipelines is improved.

Description

technical field [0001] The invention relates to the field of aero-engine structures, and in particular provides a double-thread connection structure for pipelines passing through the casing, with a diameter of φ10-φ20 mm. Background technique [0002] The pipes passing through the casing on traditional engines adopt different connection and sealing structures according to their diameters and transmission media. Generally, pipelines with a diameter of φ8~φ36 adopt a one-piece sealing structure that passes through the casing, that is, the joints on the pipeline in the casing are exposed outside the casing, and the ball and socket structure is used to seal the pipeline and the casing. compensate. [0003] Due to the limitation of the laying space of the external joint extending out of the casing, the bent pipe structure is often used to reduce it to the height of the casing. Therefore, when it is necessary to disassemble the casing in half for condition-based maintenance, a la...

Problems solved by technology

[0003] Due to the limitation of the laying space of the external joint extending out of the casing, the bent pipe structure is often used to reduce it to the height of the casing. Therefore, when it is necessary to disassemble the casing in half for condition-based maintenance, a large amount of disassembly is required to remove the pipeline passing through the casing. The structure can only be realized, and the workload is relatively large
