Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with tool
This programme is discussed in detail by body embodiment further.
As it is shown on figure 3, the storage device of the SCR reducing agent of embodiment of the present invention offer, including casing
100, described casing 100 is provided with filler assembly 200 and tap hole assembly 300, be respectively used to
The SCR reduction retained in filling SCR reducing agent in described casing 100 and releasing described casing 100
Agent.Wherein, the filler in described filler assembly 200 connects that to stretch to described casing 100 internal
Filler extension tube 210, described filler extension tube 210 and the liquid level in described casing 200 it
Between there is default inclination angle.The inside of described casing 100 is additionally provided with urea level temperature sensor 400,
The liquid level of SCR reducing agent and temperature in use monitoring casing, and relevant letter
Number pass to ECU, and then SCR system is controlled.It addition, be additionally provided with logical on described casing 100
Air-valve assembly 500, described breather valve assembly 500 includes that the ventilation stretched in described casing 100 is prolonged
Stock 110, the inside of described ventilation extension rod 110 is provided with venting channels 113, and described ventilation extends
The bar 110 sidewall near bottom is provided with the first passage 111 communicated with described venting channels 113,
Described first passage 111 can arrange one or circumferentially multiple；In described casing 100
The full liquid level position of design is higher than described first passage 111 and the opening of described filler extension tube 210
The position at place.
When SCR reducing agent is added to casing 100, owing to SCR reducing agent occupies casing 100
Space, the air within casing 100 will be compressed, and the air after compression can be along the first passage
111, it is discharged in air by described exhaust valve component 500.When urea pump works, casing 100
The when of the SCR reducing agent sucking-off of the inside, volume inside casing 100 increases, and air expansion enters
And the air in air is sucked in casing 100 along above-mentioned passage, thus balance box 100 is with big
Pressure between gas.
Filling SCR reducing agent, when being filled into position as shown in Figure 5, SCR reducing agent can cover
First passage 111, owing to the first passage 111 aperture is less, adds that the surface tension of liquid is made
With, during only part SCR reducing agent enters venting channels 113.In order to avoid in venting channels 113
Air flowing too fast and cause liquid to overflow, described venting channels 113 is preferably placed with ventilation and delays
Rush cap 120, as shown in Figure 4, described asv buffer cap 120 and the sidewall of described venting channels 113
Between there is prepsetting gap.SCR reducing agent is entered between described presetting by described first passage 111
In gap, when in SCR reducing agent enters into venting channels 113 and when forming certain liquid level, logical
Gas buffer cap 120 can float over ullage.
Continue to add SCR reducing agent, the liquid level at described filler extension tube 210 in casing 100
Reaching state as shown in Figure 6, display can not be further continued for adding liquid, but now actual liquid level and design
Full fluid level condition be consistent.Now stop adding SCR reducing agent, in ventilation extension rod 110
Liquid level may proceed to raise, and when liquid level reaches certain height, the pressure at the first passage 111 reaches
Balance, now the SCR reducing agent in casing will not continue to enter venting channels 113.
As shown in Figure 4, described ventilation extension rod 110 is also preferably equipped with and institute on the sidewall on top
State the second passage 112 of venting channels 113 connection, the breathing area of described second passage 112
Less than the breathing area of described first passage 111, the second described passage 112 typically arranges one
Individual.When pressure at the first passage 111 reaches balance, air still can pass through the second passage 112
Place discharges endlessly, now the liquid level at filler extension tube 210 and venting channels 113
Will decline, the liquid level in final casing 100 is concordant, reaches state as shown in Figure 7, it is to avoid
At filler extension tube 210, liquid level is too high and there is the risk of discharge.
As shown in Figure 4, described breather valve assembly 500 also includes breather valve main body 130 and described logical
Ventilation valve gap 150 that vent cover in air valve main body 130 connects and connecting with described ventilation valve gap 150
Breather 160, specifically, described ventilation valve gap 150 be provided with ventilation valve gap through hole 151, described
Breather 160 is connected with described ventilation valve gap through hole 151.It is also covered with waterproof over said opening
Air film 140, when the gas in casing 100 discharges, through described waterproof ventilated membrane 140 by gas
SCR reducing agent in body, prevents it to be discharged in environment and pollutes.
Preferably, it is additionally provided with two groups of deflectors 134 in described breather valve main body 130, leads described in two groups
Stream plate 134 forms the V-arrangement flow-guiding channel of opening upwards, as shown in Figure 4, through described waterproof and breathable
The SCR reducing agent that film 140 filters out, under the guide functions of described deflector 134, is led by described
Circulation road flows back to casing 100.
SCR reducing agent is driven to form siphonage, described breather valve master in order to prevent air from quickly gushing out
Gas reducing-flow structure it is provided with in body 130.Specifically, as shown in Figure 8 and Figure 9, described breather valve master
Being provided with bottom baffle 131 in body 130, described bottom baffle 131 is provided with the ventilation that supplied gas is passed through
Duct 132.Described vent cap 132 is preferably dual arcuate hole road, as shown in Figure 8, described pair of arc
Shape duct refers to that duct includes former and later two adjacently positioned concentric arcs holes.Described vent cap 132
It is preferably three groups, and described in three groups, vent cap 132 is circumferentially evenly arranged.
Further, the edge of described vent cap 132 also can be provided with and be perpendicular to described bottom baffle 131
The axial baffle 133 arranged, gas by need after described vent cap 132 to again pass through described axially
Baffle plate 133, further increases the resistance of flowing.It is dual arcuate hole road at described vent cap 132
Scheme in, the preferably inside edge at the adjacent edge of two arcuate sockets and inner side arcuate socket is all provided with
Put described axial baffle 133, as shown in Figure 9.
Described axial baffle 133 can be arranged above or below described bottom baffle 131, preferably court
Extend to the direction of described ventilation valve gap 150.So, when the gas in casing 100 is discharged, institute
State axial baffle 133 and also the SCR reducing agent in gas is had the effect of separation, gas and described axle
After baffle plate 133 clashes into, beneficially SCR reducing agent separates.
The structure of the present invention, feature and effect effect are described in detail above according to graphic shown embodiment
Really, the foregoing is only presently preferred embodiments of the present invention, but the present invention does not implements to limit shown in drawing
Scope, every change made according to the conception of the present invention, or it is revised as the equivalence enforcement of equivalent variations
Example, still without departing from description with diagram contained spiritual time, all should be in protection scope of the present invention.
