Description

Technical Field

[0001] The utility model relates to a tail gas treatment liquid filling pipe. Background Art

[0002] At present, the filling pipe used to add exhaust gas treatment liquid to diesel vehicles is limited in length. During the filling process, the filler needs to adjust the position of the treatment liquid barrel, which is very physically demanding. In addition, the connection between the filling pipe and the urea barrel is not fixed. When the filler pours the exhaust gas treatment liquid in the urea barrel into the car urea tank, the exhaust gas treatment liquid is easy to leak to the outside, resulting in a waste of exhaust gas treatment liquid. This filling method requires the operator to carry it, which increases the workload of the filler and the filling efficiency is relatively low. In view of this, this invention is specially applied for. Utility Model Content
