Description
Technical field
The utility model is related to a kind of post processings of vehicle exhaust to prevent leakage of urine element encapsulating structure, belongs to auto parts technology neck
Domain.
Background technology
It is higher and higher with environmental requirement, motor vehicle exhaust emission regulation it is increasingly strict, exhaust aftertreatment technology is must
The technical measures that must be used.And SCR disclosure satisfy that state IV, V and VI discharge standard of state.The packaging technology of SCR simplifies, and reduces cost
Also it is more and more important.Common processes are that inner assembly welding is completed first, and then inner assembly is decorateeed with cylinder, then assembly welding disengaging
Tracheae component.But it is that three stackings add that the technique, which is welded into air outlet pipe component, internal components welding process, element size requirement
Compare high, extremely be easy to cause weld seam rosin joint, solder skip, SCR encapsulation is caused leakage of urine element phenomenon occur.
The content of the invention
The purpose of the utility model is to overcome there is the shortcoming of leakage of urine element during existing SCR encapsulation uses, provide
A kind of vehicle exhaust post processing prevents leakage of urine element encapsulating structure.
The technical solution of the utility model, vehicle exhaust post processing prevent leakage of urine element encapsulating structure, including end cap, eliminate the noise
Pipe, partition plate and cylinder；The cylinder one side is equipped with end cap, is additionally provided with hush tube in cylinder, hush tube is matched somebody with somebody by partition plate and cylinder
Close connection；Further include flange and blanking cover；One end that the hush tube stretches out end cap is connected with flange, and hush tube is located at inner barrel
One end be equipped with blanking cover.
The hush tube with end cap and partition plate by being welded to connect, also by being welded to connect between hush tube and flange.
By being welded to connect between the end cap and partition plate and cylinder.
Sensor connector is additionally provided on the hush tube.The hush tube is integrally formed.
The beneficial effects of the utility model：The utility model reduces component part, easy to use；Its inner assembly welds
When, it requiring to reduce for product fit dimension, for hush tube directly with end cap flanging welded, welding is easy during welding, weld seam is beautiful,
Securely.The utility model also reduces the application risk of client.

Specific embodiment
As shown in Figure 1, vehicle exhaust post processing prevents leakage of urine element encapsulating structure, including end cap 2, hush tube 3,4 and of partition plate
Cylinder 6；6 one side of cylinder is equipped with end cap 2, is additionally provided with hush tube 3 in cylinder 6, hush tube 3 is coordinated by partition plate 4 and cylinder 6
Connection；Further include flange 1 and blanking cover 5；One end that the hush tube 3 stretches out end cap 2 is connected with flange 1, and hush tube 3 is located at cylinder
One end inside 6 is equipped with blanking cover 5.
The hush tube 3 with end cap 2 and partition plate 4 by being welded to connect, also by welding between hush tube 3 and flange 1
Connection.
By being welded to connect between the end cap 2 and partition plate 4 and cylinder 6.
Sensor connector 7 is additionally provided on the hush tube 3.The hush tube 3 is integrally formed.
The utility model hush tube 3 directly with 2 flanging welded of end cap, reduces leakage of urine element.Wherein hush tube 3 and flange 1,
Partition plate 4, end cap 2 and blanking cover 5 are welded as inner assembly, are decorateeed in cylinder 1, assembly welding.The welding category of hush tube 3 and end cap 2
It is welded in individual layer, welding becomes easy, and weld seam is secured, beautiful, can effectively prevent that leakage of urine is plain.
The utility model is changed to dual-layer welding by three layers of welding, solves existing SCR by the variation of 3 length of hush tube
Occur leakage of urine Plain Questions topic during encapsulation use, provide it is a kind of simple in structure, without increasing the scheme of part.
Variation that those of ordinary skill in the art makes in the essential scope of the utility model, remodeling, addition or
It replaces, should also belong to the protection scope of the utility model.
