Description
Technical field
This utility model is related to a kind of urea pump, more particularly, to a kind of urea pump of tilting air valve.
Background technology
Gas circuit runner is requisite pith in air auxiliary urea pump, at present, liquid non-return valve outlet, gas
One-way valved outlet, mixture outlet are in same horizontal plane；Mixing intracavity Liquid backwash is easily caused to air passage one-way valve.Liquid
When body check valve is opened, it is most likely that spray into the cooling gas check valve valve core inside opened；Presence does not purge clean showing completely
As, easily produce cooling gas check valve and be immersed in urea liquid, once it is poorly sealed (as knot occurs in local air passage one-way valve occur
It is brilliant), will result in liquid and enter inside air passage one-way valve；In the case of the stagnation of vehicle long-time or temperature are higher, gas is accumulated in
The liquid of road check valve is easily crystallized.
Disadvantages mentioned above affects the stability and feature of urea pump, becomes anxious to be resolved one of those skilled in the art and asks
Topic.
Utility model content
The purpose of this utility model is to provide a kind of urea pump of tilting air valve, to solve in prior art in urea pump
The problems referred to above that each runner arrangement is present.
It is that, up to this purpose, this utility model is employed the following technical solutions：
A kind of urea pump of tilting air valve, which includes housing and the gas circuit runner being opened in the housing, liquid flow
Road and mixing runner, the gas circuit runner and flow channel for liquids are connected with the mixing runner, and are set in the gas circuit runner
Cooling gas check valve is equipped with, fluid path check valve in the flow channel for liquids, is provided with, wherein, the outlet of the gas circuit runner, liquid flow
The outlet in road and the outlet interlaced arrangement of mixing runner, the gas circuit runner are in tilted layout, and the cooling gas check valve is inclined to be installed
In the gas circuit runner, and the outlet open height of the cooling gas check valve is less than the rational height of the other end.
Especially, 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
Centre position, the liquid outlet of the mixing runner are in extreme lower position.
Especially, the liquid outlet of the fluid path check valve is provided with ring-type injection step, reduces high-pressure injection liquid out
Body kinetic energy, it is to avoid liquid is directly injected to cooling gas check valve.
The beneficial effects of the utility model are that the urea pump of the tilting air valve has following excellent compared with prior art
Point：
1) by tilting gas circuit runner, cooling gas check valve is lifted to into hybrid chamber extreme higher position, urea liquid is using deadweight
Wander about as a refugee air passage one-way valve；
2) fluid path check valve Front-end Design circlewise sprays step, reduces high-pressure injection liquid kinetic energy out, it is to avoid liquid
Body is directly injected to cooling gas check valve；
3) structure that whole urea tank fills assembly is simplified, is easy to assembling, Stability Analysis of Structures reliability.

Specific embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
Refer to shown in Fig. 1 to Fig. 4, in the present embodiment, a kind of urea pump of tilting air valve includes housing 1 and is opened in
Gas circuit runner 2, flow channel for liquids 3 in the housing 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 is provided with fluid path check valve 5, the outlet of the gas circuit runner 2, flow channel for liquids in the flow channel for liquids 3
3 outlet and the outlet interlaced arrangement of mixing runner 4, the gas circuit runner 2 are in tilted layout, and which is tilted to be provided with gas unidirectional
Valve 6, the rational height of the outlet open height of the cooling gas check valve 6 less than the other end make urea liquid wander about as a refugee gas using deadweight
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
Put, 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 ring-type injection step 7, reduces high-pressure injection liquid out and moves
Can, it is to avoid liquid is directly injected to cooling gas check valve 6.
The tissue of the air-flow and liquid stream of the urea pump of above-mentioned tilting air valve and mixing are as far as possible away from gas outlet, even if purging is not
Completely, using action of gravity, be not in cooling gas check valve immersion phenomenon in a liquid.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model does not receive above-mentioned example
Limit, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and change, these changes
Change and change and both fall within the range of claimed this utility model.The claimed scope of this utility model will by appended right
Ask book and its equivalent thereof.
