Abstract
The utility model provides a urea tank in a urea injection system. The urea tank in the urea injection system comprises a tank body, a tank internal urea pipe arranged in the tank body and a liquid discharge port formed in the bottom of the tank body. The urea tank in the urea injection system further comprises a flange in threaded connection with the tank body, wherein an air inlet, an air outlet, a urea solution outlet and a heating pipeline are arranged on the flange, the upper end of the urea pipe is fixed in the urea solution outlet, and a liquid level meter is further arranged on the outer side of the tank body. The liquid level of liquid in the urea tank can be checked visually through the added liquid level meter, and thus using and operation are more convenient; the flange and the tank body are designed to be in the threaded connection, mounting is more convenient, sealing performance and the stability are better, and maintenance and liquid filling are facilitated. The urea tank in the urea injection system has better performance and is good in practicality.
Description
Technical field
The utility model relates to the urea tank in a kind of SCR urea-spray system.
Background technique
At present, urea tank is generally applied to large-sized diesel car, for reducing the nitrogen oxide of motor vehicle emission tail gas, reduces the environmental pollution bringing because of exhaust emissions.Urea tank is generally installed on automobile frame outside, and liquid automobile urea itself is easy to store and carry, and therefore the sealing of urea tank, steadiness is required very highly, and existing urea tank is still to be improved.
Model utility content
Problem to be solved in the utility model is that design is a kind ofly applied in urea-spray system, easy accessibility, observable liquid level urea tank.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the urea tank in a kind of urea-spray system, comprise the tap hole that the interior urea tube of the tank arranging in tank body, tank body and tank base are installed, also comprise the flange being threaded with tank body, flange is provided with suction port, relief opening, urea liquid outlet and heating pipe line, it is upper that the upper end of urea tube is fixed on urea liquid outlet, and tank body outside is provided with level meter.
Further, suction port, relief opening, urea liquid outlet arrange respectively inflation solenoid valve, pressure-releasing electromagnetic valve, carbamide injection valve.
Further, mounting temperature sensor, liquid level sensor and pressure transducer on flange.
Further, heating pipe line is comprised of water intake, heater, water outlet; Wherein water intake is connected with engine water pump outlet port circulating water, and water outlet communicates with circulating water of engine low voltage terminal.
Further, between water intake and engine water pump discharge, be also installed into water solenoid valve.
Further, level meter two ends are provided with threaded pipe, and threaded pipe is connected with the tapped hole of corresponding setting on tank body.
Further, level meter has transparent windows.
Advantage and the good effect that the utlity model has are: the level meter of increase can be checked the liquid level of urea pot liquid intuitively, use more convenient to operate, flange becomes to be threaded with tank design, it is more convenient to make to install, sealing, steadiness are better, facilitated maintenance and filling liquid, this urea tank has more optimal performance simultaneously, and practicability is good.
