Description

A kind of urea electric heating pipeline for SCR system
Technical field
The utility model relates to a kind of urea electric heating pipelines for SCR system, belong to automobile urea transfer conduit neck Domain.
Background technique
As motor vehicle is using more and more, the discharge of bring harmful and noxious substance is also more and more.Therefore, national IV discharge standard requires to further decrease the harmful substance of the exhaust emissions of motor vehicle.SCR technology is current reduction Diesel NOx A kind of effective method of discharge.But since urea liquid subzero is easy to happen crystallization, lead to pipe blocking, institute To need the urea pipe of hot type to meet its needs to guarantee diesel engine normal use during the cold season.Current urine The heating of plain pipeline is typically just heated in outer tube winding resistance wire, is caused heated slow and uneven and prolonged Heating is easy that urea pipe outer wall is made to be carbonized, and causes short-circuit kindling, very dangerous.Therefore, it is necessary to be directed to the structure of urea pipe Do more optimal improvement.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art provides a kind of design of structure more Adduction reason, the heated fast and more stable performance urea electric heating pipeline for SCR system.
In order to solve the above technical problems, the utility model provides a kind of urea electric heating pipeline for SCR system, packet Include urea tube, it is characterised in that:Parallel and spiral offers one group of groove in the axial direction on the tube wall of the urea tube;It is described Heating material is wound in groove;The urea tube is coated with insulation heat preservation layer;Guarantor is coated with outside the insulation heat preservation layer Sheath.
The technical solution that the utility model further limits is:The groove is even number item, and at least 2, and two-by-two On the both ends tube wall of same diameter on the same longitudinal section of urea tube.
Further, the groove is two, is located at two end pipes of same diameter on the same longitudinal section of urea tube On wall.
Further, the longitudinal section of the groove is U-shaped.
Further, the heating material matches after being wrapped in groove with groove shapes and surface maintains an equal level.
Further, the heating material is heating tape or heater strip.
Further, the heating material is electrically connected with connecting terminal.
It further, further include the connector for being mounted on urea tube end.
Further, the connector side is equipped with the side plug being electrically connected with heating material.
It further, further include that the temperature sensor surveyed and be electrically connected on the inside of plug by side plug is set.
The utility model has the beneficial effects that:The urea electric heating pipeline for SCR system of the utility model is heated more Fastly, it conducts heat more uniform, temperature control flexibly, so that the temperature in urea pipe is in constant state always, avoid urea Solution crystallizes, and ensure that the normal operation of diesel engine.The utility model simple structure and convenient processing, it is at low cost and Long service life, safety and environmental protection and insulating properties are good.
Detailed description of the invention

Specific embodiment
Embodiment 1
A kind of urea electric heating pipeline for SCR system provided in this embodiment, it is described picture 1-4:It is fast including first Fast plug 6, the second plug 5, urea tube 1, urea tube 1 tube wall on parallel in the axial direction and spiral offer U-shaped groove 1-1 With groove 1-2;Groove 1-1 and groove 1-2 is located on the same longitudinal section of urea tube on the both ends tube wall of same diameter.It is recessed The matched heating tape 4 of shape therewith is wound in slot;Maintain an equal level after heating tape is wrapped in groove with groove surfaces.The present embodiment will Urea tube is designed to groove structure, first is that increasing the contact area of heating tape Yu urea tube wall, makes heated more Quick uniform; Second is that the heating design of groove structure is that pipeline appearance more refines and is not take up too many space structure.
The side of second plug 5 is equipped with the side plug 8 being electrically connected with heating material;Heating tape 4 and setting are in the plug of side Connecting terminal electrical connection, the inside of side plug 8 is also electrically connected with a temperature sensor 7.In addition, urea tube is coated with insulation Insulating layer 2 is with urea pipe anti-aging kindling;Matcoveredn 3 is coated outside insulation heat preservation layer 2.General protective layer uses plastics wave Line pipe.
Groove in the present embodiment is 2, but is not limited to 2.In addition to the implementation, the utility model can also have Other embodiments.All technical solutions formed using equivalent substitution or equivalent transformation, all fall within the guarantor of the requires of the utility model Protect range.
