Abstract
The utility model provides an EGR (Exhaust Gas Recirculation) pipe seat assembly, which comprises a pipe body; and one end of the pipe body is connected with a flange. The EGR pipe seat assembly is characterized in that a corrugated pipe is arranged at the other end of the pipe body; a plug cover is arranged at the outer end of the corrugated pipe; and a flattening part at the front end of the plug cover and the corrugated pipe are integrally formed. The EGR pipe seat assembly has the advantages that the structure is simple, and the installation and use are convenient; the welding is not required, so that the service life is prolonged, and the cost is saved; pipe fittings are firmly connected; heat transfer is isolated; and gas is uniformly dispersed from the side surface, so that the working environment of a sensor is improved, and the occurrence of interference phenomenon is prevented.
Description
Technical field
The utility model belongs to the auto parts and components field, specifically is a kind of EGR base assembly.
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.Common EGR base does not have blanking cover, and gas flings sensor, influences sensor sensitivity and life-span, does not have the gland flange part, is not easy to be fastenedly connected, and does not have bellows and thermal shield, and inconvenience is installed, and working life is short.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of EGR base assembly.
A kind of EGR base assembly comprises body, and an end adpting flange of body is characterized in that being provided with bellows at the other end of body, is provided with blanking cover in the outer end of bellows, and the flattening part and the bellows of said blanking cover front end are one-body molded.
Described EGR base assembly is characterized in that being provided with gland flange in the inner of bellows.
Described EGR base assembly is characterized in that body is provided with thermal shield.
Described EGR base assembly is characterized in that said flange is provided with breach.
The EGR base assembly of the utility model, simple in structure, easy to install, need not to improve working life through welding; Practice thrift cost, pipe fitting connects fastening, isolated heat transfer; And gas is evenly scattered from the side, improve the working sensor environment, and prevent interference phenomenon.
Description of drawings
Fig. 1 is the schematic representation of a kind of EGR base assembly of the utility model;
Among the figure, 1-blanking cover; 2-bellows; 3-O type circle; 4-gland flange; 5-clip; 6-thermal shield; 7-flange; 8-breach.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, a kind of EGR base assembly of the utility model comprises body; One end adpting flange 7 of body is provided with bellows 2 at the other end of body, is provided with blanking cover 1 in the outer end of bellows 2; The flattening part and the bellows 2 of blanking cover 1 front end are one-body molded; Be provided with gland flange 4 in the inner of bellows 2, body is provided with thermal shield 6, and flange 7 is provided with breach 8.
The blanking cover front end of the utility model flattens part and bellows is linked to be an integral body, need not to have practiced thrift cost when improving working life through welding; The gland flange part that increases is easy to pipe fitting and connects fastening; The bellows that increases can conveniently be installed, and can increase working life during use; The thermal shield that increases plays the transmission of isolated heat; The blanking cover that increases goes out gas from the side, evenly scatters, and improves the working sensor environment; Sub-fraction that flange cuts away forms breach, prevents interference phenomenon not influencing under the intensity.
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.
