Description
Technical field
The utility model is related to a kind of liquid level sensor, and diesel vehicle engine vent gas treatment is used for more particularly, to one kind
Electrical heating urea liquid level sensor in system.
Background technology
In order to reduce diesel vehicle exhaust emissions, strengthen environmental protection, after state four, the diesel vehicle of state more than five all install tail gas additional
Treatment technology, increased urea solution spraying system in Engine exhaust pipeline.Because the apparent freezing point of urea liquid is -11 DEG C,
Urea liquid below this temperature be able to can not flow as ice, make post processing ineffective, and not reaching should be effective.Mesh
Urea liquid level sensor with vehicle in front is all using traditional water circulation heater, for being heated to urea solution, to solve
Certainly, there is many use defects in the use problem under its low temperature：
1) when environment temperature is less than icing of urea solution temperature, the urea in urea box will not flow in icing condition
It is dynamic, now because the coolant of engine is in a low temperature of identical, it is impossible to urea liquid heating and melting, exhaust aftertreatment system
System can not obtain the participation of urea liquid and ineffective, cause exhaust emissions exceeded；
2) engine coolant is introduced into urea box to heat urea liquid, additional cycles water lines is wanted in vehicle assembling
And the part such as magnetic valve, the complexity of vehicle assembling is increased, while material and assembling cost of labor are also increased, if using
Occur coolant in journey and omit problem, harmful effect can be brought to engine-cooling system and after-treatment system.
Utility model content
The purpose of this utility model is to provide a kind of electrical heating urea liquid level sensor, and it has and is easily installed, uses
The characteristics of convenient, low cost and good heating effect, to solve what the water-cycle heating that vehicle is used in the prior art brought
Many deficiencies.
It is that, up to this purpose, the utility model uses following technical scheme：
A kind of electrical heating urea liquid level sensor, it includes the seat of honour, electric heating tube, urea pipette and sensor cluster,
Wherein, the electric heating tube, urea pipette and sensor cluster are connected to the bottom at the seat of honour, the urea pipette
Bottom is connected with filtering pack assembly, and the filtering pack assembly is wrapped with electrical heating module, the electrical heating inside modules and institute
Electric heating tube is stated to be connected by electrical heating wire.
Especially, the seat of honour is directly installed on vehicle urea box by the interface being engaged with vehicle urea box.
Especially, the lower end of the sensor cluster is fixed on the filtering pack assembly, plays the reinforcing that interfixes and makees
With.
Especially, the electrical heating module includes the pedestal of circular arc, and snap part, the electricity are provided with the pedestal
Heater strip is fixed on the pedestal by snap part, and overall serpentine-like distribution.
Especially, outlet lid is provided with the seat of honour, the electrical heating wire is drawn and led to through electric heating tube from outlet lid
Cross electric wire connection power connection.
Especially, stop block is provided with the top of the sensor cluster, and its middle part is provided with ball float.
The beneficial effects of the utility model are that the electrical heating urea liquid level sensor is in original compared with prior art
Install electric heater unit on urea liquid level sensor additional, direct electro heating is used when environment temperature is less than icing of urea solution temperature
Mode quickly effective dissolved urea can freeze, and be not only simple in structure, easy to use；And low cost, heating effect is good, it is ensured that
The normal operation of after-treatment system.
