The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application in no tangible proof
In the case of disclosed, above-mentioned background technology should not be taken to evaluate the novelty and creativeness of the application.
Utility model content
The utility model provides a kind of engine simple in construction, highly reliable, dismounting is easy for above-mentioned technical problem
Supply bimetallic tube.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of gas engine supply bimetallic tube, including inner tube, outer tube, in addition to mounting flange, the installation
Air vent is distributed between flange center's circle and bolt eyelet；The port of the inner tube and the outer tube is together attached to institute
State on mounting flange, the inner tube is distributed in inside the outer tube, and the air vent is distributed in the internal layer tube wall
Between the outer layer tube wall.
Further, the both ends of the inner tube and the outer tube are all respectively combined with a mounting flange.
Further, the inner tube, the outer tube and the mounting flange are made of metal material.
Further, the outer tube is divided into two sections from middle part, and two segment length sums of the outer tube are less than described
Inner tube overall length, so that the both ends of the inner tube and the outer tube can be welded with the mounting flange；Simultaneously
Sleeve is also distributed with the outer tube segmentation, the intersegmental gap of the outer tube two is covered sealing, weldering by described sleeve pipe
It is connected in the outer layer pipe outer wall.
Further, the inner tube external diameter matches the mounting flange center circle diameter, by inserting the Method for Installation
Blue center circle is welded to connect.
Further, the inner tube, the outer tube and the mounting flange are integrally formed by 3D printing technique.
Further, in addition to a pad, the pad match the mounting flange.
The beneficial effect of the utility model compared with prior art：The utility model passes through the connection method provided with uniqueness
Orchid, realize that inner tube and outer tube can share same flange, be substantially distinguished from conventional art, turning into batch industrialization production can
Can, when in use, it need to only be connected one by one by the adpting flange at the utility model both ends, pair of length needed for composition
Layer pipeline, very easy and highly reliable, dismounting simplicity is not only operated, is easy to later period maintenance replacing, compared with prior art side
Case has the progress of prominent substantive distinguishing features and conspicuousness.

Embodiment
Specific embodiment 1
As shown in Fig. 1~2, a kind of gas engine supply bimetallic tube, including inner tube 4, outer tube 2；Also include peace
Flange 1 is filled, air vent 9 is distributed between the center circle of mounting flange 1 and bolt eyelet 8；The inner tube 4, the outer layer
Pipe 2 and the mounting flange 1 are made of metal material.The inner tube 4 is distributed in inside the outer tube 2, that is, forms one
The vent passages 3 of blast tube 5 and one；The outer tube 2 is divided into left section of 2-1 and right section of 2-2, left section of 2-1's of the outer tube 2
The left port of external port and the inner tube 4 is together attached on a mounting flange 1, meanwhile, the right side of the outer tube 2
Section 2-2 external port is also together attached on another mounting flange 1 with the right output port of the inner tube 4；The air vent 9
It is distributed between the tube wall of inner tube 4 and the tube wall of the outer tube 2, makes to communicate with the vent passages 3.In order to beneficial to internal layer
Pipe 4, outer tube 2 and the welding of mounting flange 1, left section of 2-1 of the outer tube 2 and right section of 2-2 overall length are less than the inner tube 4
Overall length.When being welded, first the inner tube 4 of left end, outer tube 2 and mounting flange 1 are welded, then again by outer tube 2
Right section of 2-2 move to the left, then the right-hand member of inner tube 4 and another mounting flange 1 are welded, then weld outer tube again
2 right section of 2-2 outer end, and the space thus formed between the left section of 2-1 and right section of 2-2 of the outer tube 2, finally by
Covering sealing is carried out provided with sleeve 6, described sleeve pipe 6 is welded on the outer wall of the outer tube 2.Meanwhile it is additionally provided with a pad
7, the pad 7 matches the mounting flange 1.When in use, only the utility model need to be passed through the Method for Installation at its both ends one by one
Orchid 1 is attached, you can the Double layer pipeline of length needed for composition, certainly, only need to be new by this practicality for ease of being used at turning
Bend pipe is made in the ectonexine pipe of type, and the utility model can be realized by batch production, need to only pass through adpting flange when mounted
Mode just can reach the assembling requirement of Double layer pipeline, not only operate that very easy and highly reliable, degree of safety is high, be not easy out
The phenomenon that existing traditional approach leaks air because welding is bad, standard degree height is performed, while dismount simplicity, be easy to later period maintenance more
Change, scheme has the progress of prominent substantive distinguishing features and conspicuousness compared with prior art.
Specific embodiment 2
As shown in figs. 34, this specific embodiment and above-mentioned specific embodiment 1 differ only in, and the outer tube 2 is not
Segmentation, length is suitable with the inner tube 4, and the external diameter of inner tube 4 is set as to match the straight of the center circle of mounting flange 1
Footpath, it is welded to connect again by the center circle that the inner tube 4 is inserted to the mounting flange 1, certainly, described in welding
The port edge of inner tube 4 can not exceed the end face of the mounting flange 1, in favor of the connection of mounting flange, using the program,
Described sleeve pipe 6 can be also eliminated simultaneously, this specific embodiment structure is simpler, and degree of safety is higher.
