Description
Technical field
This utility model relates to urea nozzle technical field, is specially a kind of vehicle exhaust conversion urea nozzle.
Background technology
Urea nozzle is also called metering module, and usually stainless steel is made, and is typically mounted on motor vehicle exhaust emission dress
Put, under the control of ODB is loaded, the carbamide that radiacmeter ejector pump is sent here is mixed with air, so can gush out
Urea liquid is fully atomized, and is then sprayed in exhaustor, and when not spraying carbamide, nozzle only can spray air, it is ensured that nozzle is not burnt
Bad, thus, the structure of nozzle tightly must could meet requirement, and in reality, the tightness degree of some nozzles can not reach standard,
To this end, we have proposed a kind of vehicle exhaust conversion urea nozzle.
Utility model content
The purpose of this utility model is to provide a kind of vehicle exhaust conversion urea nozzle, to solve above-mentioned background technology
The problem that the tightness degree of some nozzles of middle proposition can not reach standard.
For achieving the above object, this utility model following technical scheme of offer: a kind of vehicle exhaust conversion urea nozzle,
Including air inlet pipe, the right side of described air inlet pipe is provided with middle trachea, and the right-hand member of described middle trachea is socketed with hush tube, described noise elimination
The right-hand member of pipe is socketed with conical pipe, and the top of described conical pipe is provided with pilot pin, and the right-hand member of described conical pipe is by pipeline even
Being connected to basin mouth pipe, the left end of described middle trachea connects union joint, and middle trachea is connected with air inlet pipe by union joint, described cone
The center of shape tube cavity is provided with groove, and the top and bottom of groove all has cavity, and the inner chamber of described basin mouth pipe is opened
There is unhurried current groove.
Preferably, described cavity is in axially symmetric shape about groove.
Preferably, the inwall of described union joint is provided with female thread, and the outer wall of described air inlet pipe is provided with adaptive therewith
External screw thread.
Preferably, the outer wall of described air inlet pipe is provided with back-up ring, and the junction of back-up ring and air inlet pipe is provided with chamfering.
Compared with prior art, the beneficial effects of the utility model are: this vehicle exhaust conversion urea nozzle, air inlet pipe
Being connected by union joint with middle trachea, structure is more tight, is connected firmly, and service life is more long, and cavity plays the effect of noise reduction,
Noise reduction for air-flow plays good action.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model cross-sectional structure schematic diagram.
In figure: 1 air inlet pipe, trachea in 2,3 hush tubes, 4 pilot pins, 5 conical pipes, 6 basin mouth pipes, 7 union joints, 8 cavitys, 9
Unhurried current groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of vehicle exhaust conversion urea nozzle, bag are provided
Include air inlet pipe 1, it is characterised in that: the right side of described air inlet pipe 1 is provided with middle trachea 2, and the right-hand member of described middle trachea 2 is socketed with and disappears
Sound pipe 3, the right-hand member of described hush tube 3 is socketed with conical pipe 5, and the top of described conical pipe 5 is provided with pilot pin 4, described taper
The right-hand member of pipe 5 is connected by pipeline basin mouth pipe 6, and the left end of described middle trachea 2 connects union joint 7, and middle trachea 2 is by even
Joint 7 is connected with air inlet pipe 1, and the center of described conical pipe 5 inner chamber is provided with groove, and the top and bottom of groove is all opened
Cavity 8, the inner chamber of described basin mouth pipe 6 is had to have unhurried current groove 9.
Wherein, described cavity 8 is in axially symmetric shape about groove, and symmetry is simple to manufacture, cost-effective, described union joint 7
Inwall is provided with female thread, and the outer wall of described air inlet pipe 1 is provided with therewith adaptive external screw thread, threaded more fastens, sternly
Close effective, the outer wall of described air inlet pipe 1 is provided with back-up ring, and the junction of back-up ring and air inlet pipe 1 is provided with chamfering, and back-up ring rises
To connecting fixation, chamfering reduces to be damaged.
Operation principle: air enters from air inlet pipe 1, then into middle trachea 2, air at a high speed is carried out by hush tube 3
Noise reduction process, pilot pin 4 is location when the later stage uses, it is to avoid skew of meeting and discussing, high-speed air is carried out at eddy current by basin mouth pipe 6
Reason so that air swirl, thus carbamide is gasified, uniformly, union joint 7 connects air inlet pipe 1 and middle trachea 2 so that structure in injection
Tightr.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
