SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can prevent that the carrier from taking place damaged tail gas aftertreatment encapsulation because of axial displacement.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an exhaust aftertreatment encapsulation, its includes the casing, is located carrier in the casing and being located the casing with liner between the carrier, exhaust aftertreatment encapsulation still includes and is located along the exhaust flow direction the backstop subassembly of the low reaches of carrier, wherein the backstop subassembly includes the collar and is fixed in the flexible component of collar, the collar is equipped with the trompil that is located its center, the collar is fixed in the inner wall of casing, the flexible component be used for with carrier looks butt.
As a further improved technical solution of the present invention, the carrier and the housing are provided with a gap therebetween corresponding to the gasket, and the stopper assembly is provided along a radial direction of the carrier to completely cover the gap.
As a further improved technical solution of the present invention, the mounting ring is provided with an annular mounting groove, and the flexible element is fixed in the mounting groove.
As a further improved technical scheme of the utility model, flexible component is steel wool, steel wool welded fastening is in the mounting groove.
As a further improved technical solution of the present invention, the steel wool is fixed to the mounting ring by resistance welding.
As a further improved technical solution of the present invention, the housing is provided with an edge in which the exhaust flow direction is located a sensor mounting hole in the upstream of the carrier.
As a further improved technical scheme of the utility model, the casing is equipped with annular bulge, the sensor mounting hole is located on the annular bulge.
As a further improved technical scheme of the utility model, the collar is equipped with the turn-ups portion that is located its outer fringe, turn-ups portion welded fastening in the inner wall of casing.
Compared with the prior art, the utility model discloses a set up backstop subassembly, wherein flexible element be used for with carrier looks butt. So set up, backstop subassembly not only can play limiting displacement to the carrier, also can not cause the damage to the carrier simultaneously, has reduced the carrier and has taken place damaged risk because of axial displacement.

Detailed Description
Referring to fig. 1 to 5, the present invention discloses an exhaust gas aftertreatment package 100, which includes a housing 1, a carrier 2 located in the housing 1, and a gasket 3 located between the housing 1 and the carrier 2. The gasket 3 serves to enclose the carrier 2 in the housing 1.
The exhaust aftertreatment package 100 further comprises a stop assembly 4 located downstream of the carrier 2 in the exhaust flow direction B, wherein the stop assembly 4 comprises a mounting ring 41 and a flexible element 42 fixed to the mounting ring 41. The mounting ring 41 is provided with an opening 411 in its centre, said opening 411 being arranged to allow the gas flow through the carrier 2 to continue downstream. The mounting ring 41 is fixed to the inner wall 11 of the housing 1. The mounting ring 41 is provided with a flange part 412 at its outer edge, and the flange part 412 is welded and fixed to the inner wall 11 of the housing 1. The flexible element 42 is intended to be pressed against the carrier 2 to absorb axial displacement of the carrier 2. The housing 1 is provided with a sensor mounting hole 12 located upstream of the carrier 2 in the exhaust gas flow direction B. The housing 1 is provided with an annular projection 13, and the sensor mounting hole 12 is provided on the annular projection 13.
A gap 10 corresponding to the gasket 3 is provided between the carrier 2 and the housing 1, and the stopper member 4 completely covers the gap 10 in a radial direction R of the carrier 2. The mounting ring 41 is provided with an annular mounting groove 410, and the flexible element 42 is fixed in the mounting groove 410. In one embodiment of the present invention, the flexible element 42 is steel wool welded and fixed in the mounting groove 410. The steel wool and the mounting ring 41 are fixed by resistance welding.
Compared with the prior art, the utility model discloses a set up backstop subassembly 4 can be right carrier 2 carries on spacingly, and wherein flexible element 42 is towards carrier 2, not only can play limiting displacement to carrier 2 like this, also can not cause the damage to carrier 2 simultaneously. The flexible element 42 is intended to abut against said carrier 2, reducing the risk of breakage of the carrier 2 due to axial movements.
The above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, and the understanding of the present specification should be based on the technical personnel in the technical field, and although the present specification has described the present invention in detail with reference to the above embodiments, the skilled personnel in the art should understand that the technical personnel in the technical field can still modify or substitute the present invention, and all the technical solutions and modifications thereof that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
