Abstract
The utility model provides an EGR (Exhaust Gas Recirculation) cooler connecting steel pipe. The two ends of the steel pipe are connected with flanges. The EGR cooler connecting steel pipe is characterized in that: one end of the steel pipe is connected with a flange through a bent pipe. The EGR cooler connecting steel pipe has the advantages of simple structure, convenience for using, reduction in pipe body bending difficulty, reduction in the influences of temperature and equipment vibration on a pipe body, prolonging in the service life of the pipe body, higher easiness for installing, simple processing procedure and high production efficiency.
Description
Technical field
The utility model belongs to the auto parts and components field, specifically is that a kind of cooler for recycled exhaust gas connects steel pipe.
Background technique
EGR; The air inlet side is isolated and imported to be exhaust gas recirculatioon (Exhaust Gas Recirculation) will discharge gas with compact internal combustion engine for automobile after burning a part makes its technology of burning once again, and main purpose can improve the rate of fuel consumption rate when reducing the nitrogen oxide of discharging in the gas and sharing sub load.
It is one of device of automobile exhaust recirculation that cooler for recycled exhaust gas connects steel pipe, is used to connect cooler, and it is big that common cooler for recycled exhaust gas connects steel pipe body bending difficulty; Process by one whole section body; Inconvenience is installed, and working life is short, and flange is that casting forms; Manufacturing procedure is complicated, and manufacturing efficiency is low.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of cooler for recycled exhaust gas to connect steel pipe.
A kind of cooler for recycled exhaust gas connects steel pipe, and said steel pipe two ends adpting flange is characterized in that an end of said steel pipe is connected with flange through bend pipe.
Described cooler for recycled exhaust gas connects steel pipe, it is characterized in that said bend pipe and flange are one-body molded.
Described cooler for recycled exhaust gas connects steel pipe, it is characterized in that said steel pipe is formed by connecting at least two sections bodys, connects through bellows between adjacent two sections bodys.
The kind cooler for recycled exhaust gas of the utility model connects steel pipe, and is simple in structure, easy to use, reduced body bending difficulty; Can reduce the influence of temperature and vibration equipment, increase body working life, install simpler body; Manufacturing procedure is simple, and manufacturing efficiency is high.
Description of drawings
Fig. 1 is the schematic representation that a kind of cooler for recycled exhaust gas of the utility model connects steel pipe;
Among the figure, 1-flange; 2-bellows; 3-bend pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, a kind of cooler for recycled exhaust gas of the utility model connects steel pipe, steel pipe two ends adpting flange 1, and an end of steel pipe is connected with flange 1 through bend pipe 3.Bend pipe 3 can be integrated with flange 1, and promptly an end of steel pipe is connected with the bend pipe of casting band bend pipe flange.Bend pipe has reduced body bending difficulty.Steel pipe is formed by connecting at least two sections bodys, connects through bellows 2 between adjacent two sections bodys.
In addition, the cooler for recycled exhaust gas of the utility model connects not being stamped to form with the flange of bend pipe of steel pipe, and manufacturing procedure is simple, and manufacturing efficiency is high.During use, bellows can compensates make the displacement of body generation and reduce the influence of vibration equipment to body, has increased working life, and has installed simpler.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection domain of the utility model.
