Abstract
The utility model relates to the field of automobile exhaust treatment, in particular to a pressure sensor connection rigid tube structure of an automobile exhaust treatment system. The pressure sensor connection rigid tube structure of the automobile exhaust treatment system comprises an air inlet pipe and an air outlet pipe. The air inlet pipe is of a Z shape, the air outlet pipe is of a V shape, and extension tubes are arranged on the two end portions of the V shape. By adopting the design structure, the pressure sensor connection rigid tube structure has the advantages that when a finished automobile is in the operation process, exhaust particles in a pressure sensor rigid tube slide downwards along the direction of the tube and do not accumulate in the tube or even block the tube, and therefore the accuracy of signals of a pressure sensor is guaranteed when the finished automobile is in the operation process.
Description
Technical field
The utility model relates to the vehicle exhaust process field, and the pressure transducer that relates to a kind of vehicle exhaust processing system specifically connects the hard tube structure.
Background technique
Emission of diesel engine standard formal enforcement in 2013 at present, and car load will increase the OBD monitoring.As requested; main flow monitor mode in state IV discharge phase is to increase pressure transducer at the reprocessing two ends; judge by the signal of pressure transducer whether exhaust gas processing device removes or stop up; thereby exhaust gas processing device is monitored in real time; guarantee the normal operation of vehicle, and then the protection environment.And pressure transducer is to be connected to the exhaust aftertreatment two ends by pressure transducer hard tube and pressure transducer flexible pipe, therefore the shape of pressure transducer hard tube directly has influence on the accuracy of pressure sensor signal, if pressure sensor signal output differs bigger with actual value, then can make the OBD false alarm, influence car load power.
The model utility content
The purpose of this utility model is to address the above problem, and provides a kind of pressure transducer of vehicle exhaust processing system to connect the hard tube structure.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of pressure transducer of vehicle exhaust processing system connects the hard tube structure, comprises suction tude and steam outlet pipe, and described suction tude is " Z " type, and described steam outlet pipe is " V " type, " V " type two end part band extension tube.
Two angles of turning round of " Z " type of described suction tude are all greater than 90 degree, and " V " type two end part extension tube of described steam outlet pipe is all spent greater than 90 with the angle on two limits of " V " type, is the arc transition angle between two limits of " V " type.
The beneficial effects of the utility model are: by such project organization; car load is in running; tail gas particle in the pressure transducer hard tube can move towards downward landing along pipeline; and can in pipeline, not produce accumulation; even stop up; thereby guaranteed in the car load running accuracy of pressure sensor signal.
Description of drawings
Fig. 1 is suction tude of the present utility model,
Fig. 2 is steam outlet pipe of the present utility model,
Fig. 3 is the utility model and exhaust gas processing device connection diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3.
A kind of pressure transducer of vehicle exhaust processing system connects the hard tube structure, comprises suction tude and steam outlet pipe, and described suction tude is " Z " type, and described steam outlet pipe is " V " type, " V " type two end part band extension tube.
Two angles of turning round of " Z " type of described suction tude are all greater than 90 degree, and " V " type two end part extension tube of described steam outlet pipe is all spent greater than 90 with the angle on two limits of " V " type, is the arc transition angle between two limits of " V " type.
Its design principle is: the trend of pressure transducer hard tube is designed to, and the Z coordinate of each flex point of pipeline is to increase to forward, whole pipeline trend do not have level or be tilted under trend.By such design, car load is in running, and the tail gas particle in the pressure transducer hard tube can move towards downward landing along pipeline, and can not produce accumulation in pipeline, even stops up.
What embodiment of the present utility model announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
Claims (2)
1. the pressure transducer of a vehicle exhaust processing system connects the hard tube structure, and it is characterized in that: comprise suction tude and steam outlet pipe, described suction tude is " Z " type, and described steam outlet pipe is " V " type, " V " type two end part band extension tube.
2. the pressure transducer of a kind of vehicle exhaust processing system according to claim 1 connects the hard tube structure, it is characterized in that: two angles of turning round of " Z " type of described suction tude are all greater than 90 degree, " V " type two end part extension tube of described steam outlet pipe is all spent greater than 90 with the angle on two limits of " V " type, is the arc transition angle between two limits of " V " type.
