Sealed between on the inside of line pipe both ends and urea pipe fitting；The installation locking between the urea pipe socket end and urea pipe outer wall
Fixing piece；It is in close contact between the urea tube and antifreeze liquid pipe.
Injection molding joint, the antifreeze liquid pipe are set between bellows both ends described in the utility model and urea tube connector termination
Both ends pass through the injection molding joint.
Urea tube described in the utility model includes the inner tube of EPDM materials, the high-tenacity terylene being arranged in internal layer pipe outer wall
Line layer and the rubber layer being wrapped on high-tenacity terylene line layer outer wall.
Antifreeze liquid pipe described in the utility model is nylon tube or rubber tube.
Winding bandage, tied rope or adhesive tape on the outside of the utility model urea tube and antifreeze liquid pipe.
Urea pipe fitting described in the utility model is the quick connector of resistant to urea corrosion.
The part described in the utility model that is locked is copper sheathing, iron set, stainless steel hose clamp or Plastic Bandage.
The utility model good effect is as follows：The utility model urea tube oil resistant, corrosion-resistant, high temperature resistant and high pressure resistant；Urine
Installation locking fixing piece is held tightly between plain pipe socket end and urea pipe outer wall, can so prevent urea tube Joint's falling off；It is anti-
It is nylon tube or rubber tube to freeze liquid pipe, belongs to hose, antifreeze liquid pipe is smoothly wound into urea pipe surface；Antifreeze liquid pipe is equably
Urea pipe surface and urea pipe fitting outer layer are wound into, so when the relatively low urea solution of environment temperature freezes, from engine
Anti-icing fluid has higher temperature, can be the heat transfer of engine to urea tube, so in urea tube and urea connector
Urea solution can thaw, the urea solution that thaws plays the function of processing tail gas；Wind adhesive tape and ensure antifreeze liquid pipe and urea
Good contact is kept between pipe, while reduces scattering and disappearing for heat again；Suit bellows can extend the service life of pipeline, both
Shock of the internal layer pipeline from road surface sandstone is protected, and heat-insulation and heat-preservation can be played the role of；Injection molding joint both secures ripple
Pipe, and can keep the temperature, and make the utility model beautiful.
The utility model is compact-sized, and dependable performance, reduces energy consumption, reduces with car cost.
Brief description of the drawings
Attached drawing 1 is the utility model structure diagram；
Attached drawing 2 is wrapped in the structure diagram on urea tube for the antifreeze liquid pipe of the utility model；
Attached drawing 3 is the utility model urea tube structure diagram；
Attached drawing 4 is the utility model injection molding joint structure diagram.
In the accompanying drawings:1 urea pipe fitting, 2 antifreeze liquid pipes, 3 urea tubes, 31 inner tubes, 32 high-tenacity terylene line layers, 33 rubbers
Glue-line, 4 adhesive tapes, 5 bellowss, 6 injection molding joints, 7 are locked part.
Embodiment
As shown in attached drawing 1-4, the utility model includes urea tube 3, the urea pipe fitting 1 installed in 3 both ends of urea tube, is in
Antifreeze liquid pipe 2 of the helical form uniform winding on 1 outer wall of urea tube 3 and urea pipe fitting and it is sleeved on urea tube 3 and antifreeze
Bellows 5 in liquid pipe 2；Suit bellows 5 can extend the service life of pipeline, both protect internal layer pipeline from road surface sandstone
Shock, and heat-insulation and heat-preservation can be played the role of；Injection is set to connect between 5 both ends of bellows and the inner side of urea pipe fitting 1
First 6 sealing, the injection molding joint 6 are mould filling, and urea pipe fitting 1 is the quick connector of resistant to urea corrosion.
The both ends of the new antifreeze liquid pipe 2 of this practicality pass through the injection molding joint 6；Injection molding joint both secures bellows,
It can keep the temperature again, and make the utility model beautiful.The installation locking between 1 end of urea pipe fitting and 3 outer wall of urea tube
Fixing piece 7, the part 7 that is locked are copper sheathing, iron set, stainless steel hose clamp or Plastic Bandage.It can so prevent urea pipe fitting
