Problems solved by technology
[0002] The air channel is an essential part of the air-assisted urea pump. At present, the outlet of the liquid check valve, the outlet of the gas check valve and the outlet of the mixture are at the same level; it is easy to cause the liquid in the mixing chamber to recoil to the air channel unit Directional valve
When the liquid one-way valve is opened, it is very likely to spray into the inside of the opened gas one-way valve core; if it is not completely purged, it is easy to generate gas. The one-way valve is soaked in urea solution. If the valve is not tightly sealed (such as localized crystallization), the liquid will enter the gas circuit check valve; when the vehicle is stagnant for a long time or the temperature is high, the liquid accumulated in the gas circuit check valve is easy to crystallize

Embodiment Construction
[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0018] see Figure 1 to Figure 4 As shown, in this embodiment, a urea pump with an oblique air valve includes a housing 1 and an air channel flow channel 2, a liquid flow channel 3 and a mixing flow channel 4 opened in the housing 1. Both the road channel 2 and the liquid channel 3 are in communication with the mixing channel 4, the liquid channel 3 is provided with a liquid circuit check valve 5, the outlet of the gas channel 2, the liquid channel 3 The outlet of the gas flow channel 4 and the outlet of the mixing flow channel 4 are arranged in a staggered manner. The gas channel flow channel 2 is arranged obliquely, and a gas check valve 6 is installed obliquely in it. The height of the gas outlet of the gas check valve 6 is lower than that of the other end. The height makes the urea solution flo...

The invention discloses a urea pump with a gas valve arranged obliquely. The urea pump comprises a shell, a gas channel flow pass, a liquid flow pass and a mixing flow pass, wherein the gas channel flow pass, the liquid flow pass and the mixing flow pass are arranged in the shell. The gas channel flow pass and the liquid flow pass are communicated with the mixing flow pass. The gas one-way valve is arranged in the gas channel flow pass. A liquid one-way valve is arranged in the liquid flow pass. An outlet of the gas channel flow pass, an outlet of the liquid flow pass and an outlet of the mixing flow pass are arranged in a staggered manner. The gas channel flow pass is arranged obliquely. The gas one-way valve is installed in the gas channel flow pass obliquely. The height of a gas outlet of the gas one-way valve is smaller than the arrangement height of the other end. The urea pump with the gas valve arranged obliquely is simple in structure, convenient to assemble and stable and reliable in structure. Moreover, liquid can be prevented from accumulating in the gas channel one-way valve and forming crystallization, and normal work of the urea pump is ensured.
Description
technical field [0001] The invention relates to a urea pump, in particular to a urea pump with an oblique air valve. Background technique [0002] The air channel is an essential part of the air-assisted urea pump. At present, the outlet of the liquid check valve, the outlet of the gas check valve and the outlet of the mixture are at the same level; it is easy to cause the liquid in the mixing chamber to recoil to the air channel unit to the valve. When the liquid one-way valve is opened, it is very likely to spray into the inside of the opened gas one-way valve core; if it is not completely purged, it is easy to generate gas. The one-way valve is soaked in urea solution. If the valve is not tightly sealed (such as localized crystallization), liquid will enter the interior of the gas circuit check valve; when the vehicle is stagnant for a long time or the temperature is high, the liquid accumulated in the gas circuit check valve is easy to crystallize. [0003] The above-m...
