Description
Technical field
The utility model relates to automobile after-treatment system, particularly a kind of steady type after-treatment system pressure reduction pipeline.
Background technique
Automobile exhaust system is the system of collection and discharging waste gas, generally by gas exhaust manifold, outlet pipe, preprocessor, differential pressure pickup, the compositions such as automotive muffler and tailpipe, automobile exhaust system is mainly the waste gas that discharge engine operation is discharged, make the exhaust emission pollution of discharging reduce simultaneously, reduce engine exhaust noise and waste gas is guided to suitable position.
At present, light commercial vehicle is in car load assembling, and the pressure reduction pipeline of after-treatment system nothing in vent systems is fixing, or difficult assembling, easily causes reprocessing pipe-line layout irregular, and damage also easily appears in reprocessing pipeline under shock conditions.
Summary of the invention
The purpose of this utility model is to provide a kind of steady type after-treatment system pressure reduction pipeline simple in structure, easy to use in order to overcome above-mentioned deficiency.
The utility model is achieved in that steady type after-treatment system pressure reduction pipeline, it comprises the preprocessor that is provided with preprocessor hanging, the air inlet steel pipe that one end is connected with preprocessor suction port, the steel pipe of giving vent to anger that one end is connected with preprocessor air outlet, the other end of described air inlet steel pipe and the steel pipe of giving vent to anger is connected with sebific duct, described sebific duct is provided with sensor, it is characterized in that: it also comprises dual-pipe clamp, the vertical tube part of described air inlet steel pipe and the steel pipe of giving vent to anger is connected by dual-pipe clamp, described dual-pipe clamp is provided with fixed support, described fixed support is connected with preprocessor hanger bolt.
Described dual-pipe clamp is provided with through hole, and described fixed support is provided with mounting hole, and described through hole and mounting hole are bolted.
One end of described air inlet steel pipe and the steel pipe of giving vent to anger is connected with the suction port of preprocessor and the air outlet of preprocessor respectively by pipe joint.
The utility model air inlet steel pipe and the steel pipe of giving vent to anger are fixed in preprocessor hanging by dual-pipe clamp, make its fixation in vent systems, thereby make whole reprocessing pipe-line layout neat, in the time there are vibrations, be also not easy to occur damaging, it is simple in structure, easy for installation and easy to maintenance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
