Description
Technical field
The present invention relates to a kind of urea pumps, more particularly, to a kind of urea pump of tilting air valve.
Background technique
Gas circuit runner is essential pith in air auxiliary urea pump, currently, liquid non-return valve outlet, gas
One-way valved outlet, mixture outlet are in the same horizontal plane；It is easy to cause in mixing chamber Liquid backwash to air passage one-way valve.Liquid
When body check valve is opened, it is most likely that spray into open cooling gas check valve valve core inside；Show in the presence of no purging completely is clean
As, easily generation cooling gas check valve is immersed in urea liquid, once it is poorly sealed (as part is tied air passage one-way valve occur
It is brilliant), it will result in liquid and enter inside air passage one-way valve；Under vehicle stagnation for a long time or the higher situation of temperature, gas is accumulated in
The liquid of road check valve is easy crystallization.
Disadvantages mentioned above influences the stability and functionality of urea pump, becomes anxious to be resolved one of those skilled in the art and asks
Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of urea pumps of tilting air valve, to solve respectively to flow in urea pump in the prior art
The existing above problem is arranged in road.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of urea pump of tilting air valve comprising shell and be opened in the intracorporal gas circuit runner of the shell, liquid flow
Road and mixing runner, the gas circuit runner and flow channel for liquids are connected with the mixing runner, and set in the gas circuit runner
It is equipped with cooling gas check valve, fluid path check valve is provided in the flow channel for liquids, wherein the outlet of the gas circuit runner, liquid flow
The outlet in road and the outlet interlaced arrangement for mixing runner, the gas circuit runner are in tilted layout, the cooling gas check valve inclination installation
In the gas circuit runner, and the outlet open height of the cooling gas check valve is lower than the setting height of the other end.
Particularly, the gas outlet of the cooling gas check valve is in extreme higher position, and the liquid outlet of the fluid path check valve is in
The liquid outlet in middle position, the mixing runner is in extreme lower position.
Particularly, the liquid outlet of the fluid path check valve is provided with cyclic annular injection step, reduces the liquid that high-pressure injection comes out
Body kinetic energy, avoids liquid from being directly injected to cooling gas check valve.
Beneficial effects of the present invention are that the urea pump of the tilting air valve has the advantage that compared with prior art
1) by tilting gas circuit runner, cooling gas check valve is lifted to mixing chamber extreme higher position, urea liquid utilizes self weight
It wanders about as a refugee air passage one-way valve；
2) fluid path check valve Front-end Design circlewise sprays step, reduces the liquid kinetic energy that high-pressure injection comes out, avoids liquid
Body is directly injected to cooling gas check valve；
3) structure of entire urea tank filling assembly is simplified, convenient for assembly, stable structure is reliable.

Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Shown in please referring to Fig.1 to Fig.4, in the present embodiment, a kind of urea pump of tilting air valve includes shell 1 and is opened in
Gas circuit runner 2, flow channel for liquids 3 in the shell 1 and mixing runner 4, the gas circuit runner 2 and flow channel for liquids 3 with it is described
Mixing runner 4 is connected, and fluid path check valve 5, the outlet of the gas circuit runner 2, flow channel for liquids are provided in the flow channel for liquids 3
3 outlet and the outlet interlaced arrangement for mixing runner 4, the gas circuit runner 2 is in tilted layout, tilted to be equipped with gas unidirectional
Valve 6, the outlet open height of the cooling gas check valve 6 are lower than the setting height of the other end, and urea liquid is made to wander about as a refugee gas using self weight
Body check valve 6, so that 6 head position of cooling gas check valve does not crystallize appearance.
The gas outlet of the cooling gas check valve 6 is in extreme higher position, and the liquid outlet of the fluid path check valve 5 is in interposition
It sets, the liquid outlet of the mixing runner 4 is in extreme lower position.
The liquid outlet of the fluid path check valve 5 is provided with cyclic annular injection step 7, and it is dynamic to reduce the liquid that high-pressure injection comes out
Can, avoid liquid from being directly injected to cooling gas check valve 6.
The air-flow of urea pump and the tissue of liquid stream of above-mentioned tilting air valve and mixing are as far as possible far from gas outlet, even if purging is not
It completely, is not in the phenomenon that cooling gas check valve impregnates in a liquid using gravity.
The above embodiments only describe the basic principles and characteristics of the invention, and the invention is not restricted by the above cases,
Without departing from the spirit and scope, the invention also has various changes and changes, and these changes and changes are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
