The technical solution further illustrated the present invention below in conjunction with the accompanying drawings with embodiment.It is understood that this place
The specific embodiment of description is used only for explaining the present invention rather than limitation of the invention.It also should be noted that in order to
Convenient for description, part related to the present invention is illustrated only in attached drawing and not all.
The present invention provides a kind of pipe connecting structure, and as shown in Figure 1-Figure 3, including jointing 10, jointing 10 is by steel
Pipe is processed or iron casting forms, including joint body 11 and the flange 12 for being arranged at 11 first end of joint body, joint body
Parallel interval is provided with two the first protrusions of circle 111 on 11, and the first annular groove 112 is formed between two the first protrusions 111 of circle.
As shown in Figure 4 and Figure 5, joint body 11 is inserted in the first pipe 21, and the first sealing is provided in the first annular groove 112
Circle 40；Flange 12 abuts with the second pipe 31 and passes through locking member 60 and locks, and it is close to be provided with second between 12 and second pipe 31 of flange
Seal 50；The second annular groove 311 for accommodating the second sealing ring 50 is provided on second pipe 31, and the lower cell wall of the second annular groove 311 is set
The extended segment 312 extended to the direction away from the second pipe 31 is equipped with, correspondingly, being provided with accommodating extended segment 312 on flange 12
3rd annular groove 121.
Axial seal, the second pipe 31 and flange are realized by the first sealing ring 40 between first pipe 21 and joint body 11
Radial seal is realized by the second sealing ring 50 between 12 so that the first pipe 21 seals after being connected with the second pipe 31 more to be stepped up
It is close；And after the first pipe 21 is connected with the second pipe 31, jointing 10 and locking member 60 are not easily to fall off, add the reliable of connection
Property.In the present embodiment, the first sealing ring 40 and the second sealing ring 50 preferentially select O shape rubber seal；Locking member 60 is preferential
Clip is selected, it is further preferential to select groove clamping hoop.
Further, it is provided on the second end of joint body 11 and the first pipe 21 between the end face away from the second pipe 31 pre-
Gap L is stayed, joint body 11 is made to have certain amount of movement in the first pipe 21, convenient for the assembling of the first pipe 21 and the second pipe 31.
Further, the cross section of the first protrusion 111 is arcwall face so that joint body 11 is easier to be inserted into the first pipe 21
In, and after joint body 11 is inserted into the first pipe 21, the first sealing ring 40 is close to the inner wall of the first pipe 21, plays sealing and makees
With there are minim gap between the first protrusion 111 and the inner wall of the first pipe 21, along with the section of the first protrusion 111 is arc
Face so that joint body 11 has certain angular adjustment amount in the first pipe 21, which can compensate for the first pipe 21
And the second rigging error between pipe 31.
The present invention also provides a kind of pressure charging system, referring to Fig. 4 and Fig. 5, including booster 20 and charge air cooler 30, booster 20
It is attached between charge air cooler 30 by above-mentioned pipe connecting structure, wherein, the first pipe 21 is connected to the outlet side of booster 20,
Second pipe 31 is the inlet end of charge air cooler 30.
When being attached using above-mentioned pipe connecting structure to booster 20 and charge air cooler 30, the first pipe 21 is connected to first
The outlet side of booster 20；Then the first sealing ring 40 is put into the first annular groove 112, and joint body 11 is inserted into the first pipe
In 21, during insertion, between the end face of one end that the end face of the insertion end of joint body 11 and the first pipe 21 are connected to booster 20
Reserved certain preset clearance L；Then jointing 10 is promoted, jointing 10 moves one section to close to the direction of booster 20
Distance (segment distance is less than or equal to preset clearance L), installation space is reserved for charge air cooler 30；Then charge air cooler 30, installation are installed
During charge air cooler 30, the inlet end (i.e. the second pipe 31) of charge air cooler 30 is set towards the first pipe 21, and is placed in the second annular groove 311
Second sealing ring 50, extended segment 312 can prevent the second sealing ring 50 from dropping；Then jointing 10, jointing 10 are pulled
It is moved to close to the direction of charge air cooler 30, until flange 12 is abutted with the inlet end (i.e. the second pipe 31) of charge air cooler 30；Finally use
Locking member 60 locks the inlet end (i.e. the second pipe 31) of flange 12 and charge air cooler 30.
Alternatively, when being attached using above-mentioned pipe connecting structure to booster 20 and charge air cooler 30, first in the first ring
It is put into the first sealing ring 40 in slot 112, and joint body 11 is inserted by one end of the first pipe 21 in the first pipe 21, during insertion,
Certain preset clearance L is reserved between the end face of 21 second end of end face and the first pipe of 11 second end of joint body；Then by
The second end of one pipe 21 is connected to the outlet side of booster 20；Then charge air cooler 30 is installed, charge air cooler 30 and peace afterwards are installed
Dress process is same as above, and details are not described herein.
The setting of preset clearance L causes the easier for installation of charge air cooler 30 it can be seen from above-mentioned installation process.
In addition, in practical set booster 20 and charge air cooler 30, booster 20 needs to be mounted on body by stent,
Charge air cooler 30 is also required to be mounted on body by stent, can accumulate more rigging error between the two, the in the present embodiment
The section of one protrusion 111 is arranged to arcwall face so that joint body 11 has certain angular adjustment amount, the angle in the first pipe 21
Degree regulated quantity can compensate the rigging error.Specific compensation method is, in the going out flange 12 and charge air cooler 30 with locking member 60
Before the locking of gas end (i.e. the second pipe 31), certain adjusting first is carried out to the angle of jointing 10, makes flange 12 and charge air cooler
30 outlet side (i.e. the second pipe 31) reaches optimal abutting state, then uses locking member 60 again by flange 12 and charge air cooler 30
It locks outlet side (i.e. the second pipe 31).
Further, the circle second being spaced apart with flange 12 is additionally provided on the joint body 11 of jointing 10
Protrusion 113 when pushing and pulling jointing 10, can use the second raised 113 stress point as instrument, make jointing 10
It promotes and pulls out and is more convenient.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating example of the present invention, and it is pair to be not
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement made within the spirit and principle of invention etc., should be included in the claims in the present invention
Protection domain within.
