Problems solved by technology

There are often multiple pipes with different axial and angular positions on the engine passing through the casing. Therefore, when the casing is assembled, the mounting holes of the casing need to be aligned with the positions of each pipe, which not only reduces the assembly of the casing, but also Easy to scratch and collide with the pipeline

Abstract

The invention discloses a connection structure of a vent pipeline penetrating through an engine box. The connection structure of the vent pipeline penetrating through the engine box is characterized by comprising the engine box, an engine box installation seat, a float ring, a flat connector, a bend pipe connector, a sealing barrel, a sealing gasket, a T-shaped connector and a conduit, wherein the engine box installation seat is connected on the engine box in a welded mode or in a riveting mode, the floating ring is installed between the sealing barrel and the engine box installation seat, the flat connector is connected with the bend pipe connector in a threaded mode, the sealing barrel is enabled to be assembled between the flat connector and the bend pipe connector, threaded connection is adopted between the T-shaped connector and the sealing barrel, the sealing gasket is assembled between the T-shaped connector and the flat connector, and the T-shaped connector and the conduit are welded into an inner pipeline of the engine box. The connection structure of the vent pipeline penetrating through the engine box has the advantages that the pipeline penetrating the engine box can be installed and assembling of the engine box and the pipeline is improved; the diameter of a connecting position of the inner pipeline and an outer pipeline of the engine box is reduced and the diameter of an opening hole of the engine box is effectively reduced; and the bend pipe connector and the sealing barrel are adopted in the outer pipeline of the engine box, operating space of assembling is reduced and maintainability of the assembling is improved.

Description

technical field [0001] The invention relates to the field of aero-engines, and in particular provides a connection structure for a ventilation pipeline passing through a casing, which is suitable for pipelines with a diameter of φ30-φ50. Background technique [0002] The ventilation pipeline passing through the casing on the traditional engine has a diameter of φ30~φ50. ​​In order to meet the installation of the internal and external pipelines of the casing and the sealing requirements of the casing opening, the connection structure design between the pipelines is often compared. Complicated, the diameter of the casing opening is large, which reduces the strength of the casing. Generally, through the connection structure of the casing, the inner pipe joints of the casing are mostly exposed outside the casing, and the half-type floating ring is used to match the inner hole of the casing mounting seat. This connection structure is simple to fix and reliable in sealing, but it...
