Accompanying drawing explanation
The sectional view that Fig. 1 is embodiment that the utility model provides;
The External view that Fig. 2 is embodiment that the utility model provides.
Embodiment
The utility model hereinafter described embodiment, just as example, should not limited the protection domain of claims by any way.In described embodiment, the same reference numerals in different figure all refers to the assembly of same type in this article.
Accompanying drawing 1 shows the structure of the utility model electric heating urea tube housed joint: urea liquid carries inner tube 4 ends to be equipped with quick inserting joint 1; urea connecting tube skin is the first protective casing 5; inner tube 4 and joint 1 they connection part and around outside be provided with Electric heating appliance 2; package structure encapsulates described Electric heating appliance 2, and package structure adopts partiting thermal insulation water-proofing material 3.Housed joint end is likely drawn with wire 6, and wire 6 is outer the second protective casing 7 conventionally.The first protective casing 5 and the second protective casing 7 have a segment length to be encapsulated by partiting thermal insulation water-proofing material 3.
Described urea liquid carries inner tube 4 can carry for meeting SCR system the flexible pipe of any materials requiring, and for example can adopt outer is PA12, the composite urea solution delivery hose that internal layer is ETFE.
Described quick inserting joint 1 can be the convenient any a joint being connected with SCR system miscellaneous part, the clamping often of its Placement.
In this embodiment, the first protective casing 5 and the second protective casing 7 are selected corrugated plastic flexible pipe, and its surface groove is alternate with projection.
When enforcement; quick inserting joint 1 is assemblied in urea liquid and carries in inner tube 4; the skin of urea connecting tube assembles the first protective casing 5; the heater circuit of Electric heating appliance 2 is drawn by wire 6; exterior second protective casing 7 for preparing of wire 6; then with partiting thermal insulation material, heating equipment 2 is encapsulated, encapsulation requires the first protective casing 5 and the second protective casing 7 to have in a segment length is encapsulated in.Described urea liquid can promisingly meet other layers 8 that add heat request and arrange in the middle of carrying inner tube 4 and the first protective casing 5, such as zone of heating, thermal insulation layer, watertightness barrier etc.
