Urea carry out periodical tapping, avoid water storage cavity from entering impurity.
Specifically, the water storage cavity bottom is fixed with liquid level sensor, the water storage cavity side wall is equipped with temperature sensor,
Urea pump mounting groove is equipped with above the water storage cavity.Reserved urea pump mounting groove can adapt to different urea pumps, and and storage
Liquid level sensor in water cavity is connected with temperature sensor, realizes the monitoring to liquid level and temperature.
Compared with the prior art, the advantages of the utility model are: strainer valve energy of the urea tank by setting in filter chamber
It is enough that easily the urea of filling is filtered, increase the safety of processing system, mistake or damage, filtering occur for anti-locking system
The outlet valve of intracavitary setting is for carrying out draining use when cleaning filter chamber, and when cleaning, only plug need to be inserted into valve pull-up
Upper limit hole, pressure inductor sense pressure will control strainer valve closing, at this moment cleaned from water inlet fresh water pouring,
Impurity is discharged from outlet valve, it is simple to operate, and the urea in water storage cavity is not interfered with, sealing rubber circle, which can seal, to be added
Rifle is infused, prevents extraneous dust impurity from entering in filter chamber, the sealing losing of cover of water inlet, water storage cavity bottom is prevented by anti-lost chain
Portion is controlled by control valve and is discharged.Periodical tapping can be carried out to the urea in water storage cavity, and water storage cavity is avoided to enter impurity.
