Abstract
A three-way catalyst assembly comprises an oxygen sensor, an air inlet pipe, an outer shell, an air outlet pipe, a liner and purification agents. The three-way catalyst assembly is characterized by comprising an air inlet pipe clamping groove, an air outlet pipe clamping groove and a clamping screw; the air inlet pipe clamping groove and the air outlet pipe clamping groove in the connecting part among the air inlet pipe, the air outlet pipe and the outer shell are connected through a seam allowance buckling structure. N screw holes are formed in a certain cross section of the position, near the middle, of the outer shell, the purification agents are fixed in the outer shell through the clamping screw, and N is larger than or equal to three.
Description
Technical field
The invention belongs to machinery manufacturing technology field, be specially a kind of packaging technology of ternary catalytic converter assembly.
Background technique
Along with engine power, the improving constantly of moment of torsion, oil consumption constantly reduces, and delivery temperature also improves along with the raising of combustion temperature.Therefore the waste gas that motor is discharged also gets more and more through the heat that ternary catalyzing unit is entrained, and engine assembly constantly miniaturization, thus cause ternary catalyzing unit its Surrounding Parts failure rate more and more higher, particularly electricity piece, rubber parts, working of plastics etc.Existing ternary catalyzing unit inner liner is due to long easy generation distortion service time, and this is easy to that purifying agent is produced and rocks.When ternary catalyzing unit changes purifying agent, be all generally adopt welding manner at jointing, this also makes when changing ternary catalyzing unit is also very troublesome.
Summary of the invention
For prior art problem, the invention discloses a kind of ternary catalytic converter assembly, designed by rational three stage structure, rocking of purifying agent in ternary catalyzing unit can be alleviated, simplify the step changing ternary catalyzing unit.
A kind of ternary catalytic converter assembly, comprises lambda sensor, suction tude, shell, steam outlet pipe, liner and purifying agent, it is characterized in that: comprise suction tude draw-in groove, steam outlet pipe draw-in groove and screens screw; Suction tude, attachment portion suction tude draw-in groove between steam outlet pipe with shell and steam outlet pipe draw-in groove are connected by seam fastening structure; Shell has N number of screw hole, screw hole is used for fixing screens screw, and purifying agent is fixing in the enclosure by screens screw.
Preferential, it is characterized in that: N >=3.
Its beneficial effect is as follows:
1, compare existing welding manner, this packaged type is simple, changes purifying agent processing ease, saves time.
2, in vehicle travel process, purifying agent can not rock, and ternary catalyzing unit is not fragile.
Accompanying drawing explanation
Fig. 1 is the inherent tectonic maps of ternary catalyzing unit.
Fig. 2 is that seam fastens draw-in groove tectonic maps.
Reference character, 1, suction tude draw-in groove; 2, lambda sensor; 3, suction tude; 4, steam outlet pipe draw-in groove; 5, shell; 6, screens screw; 7, steam outlet pipe; 8, liner; 9, purifying agent.
Embodiment
As shown in Figure 1, ternary catalyzing unit comprises suction tude draw-in groove 1, lambda sensor 2, suction tude 3, steam outlet pipe draw-in groove 4, shell 5, screens screw 6, steam outlet pipe 7, liner 8 and purifying agent 9.Ternary catalyzing unit main body is made up of three parts: suction tude 3, shell 5 and steam outlet pipe 7, and other parts add on these three parts bases.
Lambda sensor 2 is vertically mounted on the cylindrical pipe that suction tude 3 extends, suction tude 3, steam outlet pipe 7 are all connected by seam manner with columniform shell 5, as shown in Figure 2, such packaged type eliminates the trouble of welding, open adopt the ternary catalyzing unit of welding manner more easily to operate left-hand seat if needing compares when changing purifying agent, reduce operation easier and more save time.Shell 5 opens three screw holes close on a certain cross-section of shell intermediate portion, the purifying agent 9 in shell 5 is fixed with screens screw 6, advantage be purifying agent 9 less than shell 5 be also operable, do not worry in vehicle travel process, purifying agent 9 can rock.
Above-described embodiment is the present invention's preferably mode of execution; but embodiments of the present invention are not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
