Description
Technical field
The present invention relates to three-way catalytic converter platform experiment technical field, particularly relate to the aging making-up air device of a kind of three-way catalytic converter platform experiment.
Background technique
Along with economic fast development, automobile more and more enters people family, daily life gradually.Be with convenience to people's life, work, travelling.But simultaneously easily,, because the continuous increase of automobile quantity has caused serious pollution to atmosphere environment, the noxious pollutant transition discharges such as HC, CO, NOX, PM2.5 are piled up and have been become the serious problems that current urgent need solves.In order to reduce the discharge of harmful gas and PM2.5 content, increasing enterprise starts development and production exhaust purifier.Exhaust purifier, in R&D process, need do all kinds of demonstration tests, meets more and more stricter emission regulation demands.Stand test is one test the most frequently used, common in numerous tests.In process of the test, need to use all kinds of testing apparatuss, this wherein just relates to three-way catalytic converter quick aging tonifying Qi problem.Three-way catalytic converter is aging is divided into that car load is aging, Muffle furnace is aging and stand is aging, and car load degradation testing cost costliness is aging and unrealistic if enterprise relies on these class methods to carry out; Muffle furnace is aging is comparison common methods; Stand degradation testing cost is higher, and enterprise generally also seldom selects these class methods to carry out degradation testing.But minority whole-car firm requires supplier that stand aged samples is provided, enterprise goes the equipment of buying a kind of like this tonifying Qi not calculate specially for this reason.
Summary of the invention
Technical problem to be solved by this invention is the aging making-up air device of a kind of three-way catalytic converter platform experiment designing for above-mentioned problems of the prior art, the in the situation that this device seldom being used stand aging method but is sometimes had this generic request in enterprise, and a kind of comparatively simple and easy and testing apparatus that cost is comparatively cheap of design.This device comprises the time relay, pressure regulator valve, two-bit triplet solenoid valve, blowdown pipe condensation device and one-way valve.The time relay is the effect of controlling tonifying Qi and suspending the tonifying Qi time, pressure regulator valve is adjusted the air quantity that pressurized air enters outlet pipe, two-bit triplet solenoid valve is the switch valve of tonifying Qi, blowdown pipe condensation device is that channelling is carried out cooling to the motor exhaust at two-bit triplet solenoid valve place, in order to avoid solenoid valve is scorched, one-way valve is in order to reduce engine exhaust channelling in tonifying Qi pipeline as far as possible.Whole device can not only meet the requirement of three-way catalytic converter stand Accelarated aging test, and simple structure, with low cost.
The present invention requires the technical problem solving to be achieved through the following technical solutions:
The aging making-up air device of a kind of three-way catalytic converter platform experiment, comprise: blowdown pipe, pressure regulator valve and two-bit triplet solenoid valve, described pressure regulator valve and two-bit triplet solenoid valve are enclosed within one end of blowdown pipe successively, described pressure regulator valve is in the outside of two-bit triplet solenoid valve, described blowdown pipe the other end connecting engine outlet pipe.
Described blowdown pipe is installed one-way valve, installation time relay on described two-bit triplet solenoid valve near one end of engine exhaust pipe.
Blowdown pipe overcoat blowdown pipe condensation device between described two-bit triplet solenoid valve and one-way valve.
Described blowdown pipe condensation device is double-layer sleeve structure, forms the cavity of sealing between the internal and external layer of described double-layer sleeve structure, and the outer layer sleeve two ends of described double-layer sleeve structure respectively have a mouth, and the mouth of right-hand member is entrance, and the mouth of left end is outlet.
The inner layer sleeve of described double-layer sleeve structure contacts with blowdown pipe outer wall.
Owing to having adopted as above technological scheme, the present invention has following features:
The present invention can not only meet the requirement of three-way catalytic converter stand Accelarated aging test, and simple structure, with low cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, the present invention includes blowdown pipe 1, pressure regulator valve 2 and two-bit triplet solenoid valve 3.Blowdown pipe 1 one end is connected to (not shown) on engine exhaust pipe, and pressure regulator valve 2 and two-bit triplet solenoid valve 3 are enclosed within blowdown pipe 1 the other end, and pressure regulator valve 2 is in the outside of two-bit triplet solenoid valve 3.Blowdown pipe 1, for passing into pressurized air to engine exhaust pipe, can adopt Stainless Steel Tube.Pressure regulator valve 2 is for adjusting the air quantity that enters engine exhaust pipe.The switch valve that two-bit triplet solenoid valve 3 is tonifying Qi.
Enter blowdown pipe 1 for reduce engine exhaust as far as possible, avoid the high temperature of engine exhaust to damage two-bit triplet solenoid valve 3, near one end of engine exhaust pipe, one-way valve 4 is installed at blowdown pipe 1.Meanwhile, on the blowdown pipe 1 between two-bit triplet solenoid valve 3 and one-way valve 4, fill blowdown pipe condensation device 5.
Blowdown pipe condensation device 5 is double-layer sleeve structure, between inside and outside two sleeves, forms cavity, for splendid attire cold water, and respectively opens a mouth at the two ends of outer sleeve, is respectively used to into water and water outlet.Water (flow) direction is contrary with gas trend.
