Description
Technical field
This utility model relates to a kind of pipeline structure.
Background technology
In current automobile-used pipe-line system, the connection between different pipelines needs to use adaptor more, and this connects
Head is integral with pipe fitting welding, it is easy to assembling.This kind of type of attachment is firm, reliable, in pipe-line system
Middle extensive application.
Joint is various with the Type of Welding of pipe fitting, such as copper brazing, argon arc welding etc..At pipe fitting and weld
Before, for promote welding quality, meet product size requirement, need pre-assembled to position, determine soldering angle,
Position etc..For soldering, currently a popular location mode is artificial spot welding, and pipe fitting uses gap with joint
Coordinate.This mode production efficiency is relatively low, simultaneously when tube wall thickness is relatively thin, and the high temperature produced during spot welding,
Easily by pipe fitting burn through, cause pipeline leakage.
Utility model content
The purpose of this utility model is to provide a kind of pipeline structure, is accurately positioned pipe joint and connecting tube,
Facilitate soldering, improve and produce, reduce product rejection rate.
In order to achieve the above object, this utility model is achieved through the following technical solutions: a kind of pipeline structure,
It is characterized in, comprises:
Pipe joint, described pipe joint comprises body and the outer race section being connected with body；
Connecting tube, inserts in the outer race section of described pipe joint in the end of described connecting tube；
The outer race section of described pipe joint is provided with the first cooperation face, and the end of described connecting tube is provided with and institute
The second cooperation face that first cooperation face of stating is relative, the second described cooperation face is spaced the most successively
Interference fit district and matched in clearance district are set.
The cross section in the first described cooperation face is circular.
The polygon that cross section is band circular arc in the second described cooperation face.
The tetragon that cross section is band circular arc in the second described cooperation face.
Described interference fit district is provided with summit.
The position that the end face of the outer race section of described pipe joint contacts with described connecting tube excircle is provided with sealing
Unit.
The position that the end face of the outer race section of described pipe joint contacts with described connecting tube excircle uses soldering
Mode seals.
A kind of pipeline structure of this utility model compared with prior art has the advantage that the first of pipe joint
Cooperation face coordinate with the second of connecting tube between face formed local interference fit, local gap coordinate form,
Completing the location of pipe joint and connecting tube, facilitate and follow-up carry out soldering, production efficiency is high, and does not exists
The risk of pipeline burn-through, is greatly improved welding quality.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of pipeline structure of this utility model；
Fig. 2 is the schematic diagram of the cross section in the second cooperation face；
Fig. 3 is the schematic diagram that the first cooperation face is combined with the second cooperation face.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, this utility model is done
It is expanded on further.
As shown in Figures 1 to 3, a kind of pipeline structure, comprise: pipe joint 100, described pipe joint 100
Comprise body 101 and the outer race section 102 being connected with body 101；Connecting tube 200, described connecting tube 200
End in insert in the outer race section 102 of described pipe joint 100；The outer race section 102 of described pipe joint 100
Being provided with the first cooperation face 1021, the end of described connecting tube 200 is provided with and coordinates face 1021 with described first
The second relative cooperation face 201, the second described cooperation face 201 is spaced setting the most successively
Interference fit district 300 and matched in clearance district 400.
In the present embodiment, the cross section in the first described cooperation face 1021 is circular.
In the present embodiment, the polygon that cross section is band circular arc in the second described cooperation face 201；Relatively
Goodly, the tetragon that cross section is band circular arc in the second described cooperation face 201；Preferably, extruding institute
State the end of connecting tube 200, so that the cross section in the second described cooperation face 201 is the polygon of band circular arc
Shape.
In the present embodiment, described interference fit district 300 is provided with summit 301.
In the present embodiment, the end face of the outer race section 102 of described pipe joint 100 and described connecting tube 200
The position of excircle contact is provided with sealing unit；It is preferred that the outer race section 102 of described pipe joint 100
The position that contacts with described connecting tube 200 excircle of end face use brazing mode to seal.
Concrete application: the end of connecting tube is processed into band circular arc tetragon, in a preferred embodiment,
Use the mode carrying out the end of connecting tube extruding, make the cross section in the second cooperation face form band circular arc four
Limit shape, the end of connecting tube press-fits the outer race section inserting pipe joint, connecting tube and pipe joint contact surface shape
Become local interference fit, the form that local gap coordinates, realize location with this.
As it is shown in figure 1, after pipeline is press-fit into place, owing to there is local interference fit, connects tube and tube and connect
Will not be mutually shifted again between Tou, i.e. complete pre-determined bit, the most just can weld further.Relative to
Artificial spot welding, this mode not only increases production efficiency, there is not the risk of pipeline burn-through, significantly simultaneously
Improve welding quality.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should
Recognize that the description above is not considered as restriction of the present utility model.Read those skilled in the art
After having read foregoing, multiple amendment of the present utility model and replacement all be will be apparent from.Cause
This, protection domain of the present utility model should be limited to the appended claims.
