Abstract
The utility model relates to pipeline connection device designing technique, particularly relates to a kind of pipeline jointing construction, installs difficult and that weight is large problem to solve current pipeline jointing construction.In pipeline jointing construction of the present utility model, pipe joint and conduit to be fixed with conduit outer wall upper annular projection by pipe joint inwall upper annular groove to be connected, and has that quality is light, the advantage of high strength, is conducive to the weight reducing aeronautical product upper pipeline part; Further, do not need to carry out hot working to pipeline and pipe joint, effectively can avoid the weld defects produced in hot procedure, and process equipment is small and exquisite, without the need to carrying out follow-up heat treatment step after connection, can the process-cycle be shortened, cut down finished cost.
Description
Technical field
The utility model relates to pipeline connection device designing technique, particularly relates to a kind of pipeline jointing construction.
Background technique
In aeroengine, pipeline carries irreplaceable effect as the carrier of the various medium of transmission.
Should ensure between conduit with pipe joint to be connected reliably, the ability of joint bearing load should be not less than 90% of tubing body.Simultaneously for meeting the rigors of aerospace flight vehicle to component weight, the structure of pipe joint should be tried one's best lightly under the condition meeting intensity.
As shown in Figure 1, at home and abroad the pipeline of aeroengine connects at present, and conduit 1 and pipe joint 2 mostly are stainless steel material, and adopts the welding manners such as equal soldering and argon arc welding to be connected, and belongs to the hot worked method of metal.In conduit 1 with pipe joint 2 welding process, need complicated welding gas proterctive equipment, easily occur weld defects and welding stress, after welding, need again heat treatment step and the equipment of complicated elimination welding stress.Therefore, the requirement of traditional pipeline jointing construction to equipment is higher, and the process-cycle is longer, and welded pipe joint structure weight is comparatively large, does not meet the requirement of aeronautical product to weight.
Summary of the invention
The purpose of this utility model is to provide a kind of pipeline jointing construction, installs difficult and that weight is large problem to solve current pipeline jointing construction.
The technical solution of the utility model is:
A kind of pipeline jointing construction, comprise conduit and pipe joint, in the joint of described conduit and described pipe joint, described pipe joint inwall along the circumferential direction offers annular recess, the annular projection that the annular recess described conduit outer wall being along the circumferential direction provided with multiple and described pipe joint matches.
Alternatively, along cross section and the cross-section parallel along described pipe joint radial direction of described annular recess radial direction.
Alternatively, edge is parallel to described annular recess axis and crosses the cross section of described annular recess axis, and described annular recess is rectangular.
Alternatively, described conduit is titanium alloy conduit, and described pipe joint is titanium alloy tube joint.
The utility model has the advantage of: in pipeline jointing construction of the present utility model, pipe joint and conduit to be fixed with conduit outer wall upper annular projection by pipe joint inwall upper annular groove to be connected, have that quality is light, the advantage of high strength, be conducive to the weight reducing aeronautical product upper pipeline part; Further, do not need to carry out hot working to pipeline and pipe joint, effectively can avoid the weld defects produced in hot procedure, and process equipment is small and exquisite, without the need to carrying out follow-up heat treatment step after connection, can the process-cycle be shortened, cut down finished cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing pipeline jointing construction;
Fig. 2 is the sectional view of the utility model pipeline jointing construction.
Embodiment
Be described in detail of the present utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of pipeline jointing construction of the present utility model, comprises conduit 1 and pipe joint 2.Normally two conduits 1 are connected by a pipe joint 2.
Pipe joint 2 and conduit 1 all can adopt multiple applicable material, be titanium alloy, shape to facilitate in the present embodiment.In the joint of conduit 1 with pipe joint 2, pipe joint 2 inwall along the circumferential direction offers annular recess.Further, along cross section and the cross-section parallel along pipe joint 2 radial direction of annular recess radial direction.Further, edge is parallel to annular recess axis and crosses the cross section of annular recess axis, and annular recess is rectangular.
Conduit 1 outer wall is along the circumferential direction provided with multiple annular projection matched with the annular recess of pipe joint 2.Namely along cross section and the cross-section parallel along conduit 1 radial direction of annular projection radial direction, and the wall thickness of whole conduit 1 is consistent.
During installation, one can be adopted there is no annular projection and extend in pipe joint 2 with the conduit 1 that pipe joint 2 internal diameter matches, axially locating is carried out by frock, be positioned at inside the conduit 1 at the annular recess place of pipe joint 2 by the roller frock extruding of predetermined process equipment again, conduit 1 is made to produce plastic deformation, the part of distortion enters in annular recess, thus forms annular projection, also achieves the fixing of pipe joint 2 and conduit 1.
In pipeline jointing construction of the present utility model, pipe joint 2 and conduit 1 to be fixed with conduit 1 outer wall upper annular projection by pipe joint 2 inwall upper annular groove to be connected, have that quality is light, the advantage of high strength, be conducive to the weight reducing aeronautical product upper pipeline part.Further, in this pipeline jointing construction, do not need to carry out hot working to pipeline 1 and pipe joint 2, effectively can avoid the weld defects produced in hot procedure, and process equipment is small and exquisite, without the need to carrying out follow-up heat treatment step after connection, can the process-cycle be shortened, cut down finished cost.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
