Footpath, improve charging line move towards fluency, reduce length of pipe, arrangement FLVV valves prevent filling from regurgitating on urea box exhaust nozzle.
Increase caliber, improvement pipeline trend and diminution length of pipe can all increase arrangement difficulty, be difficult to sometimes in the useful space
Realize, and cost of parts can then be increased by increasing FLVV and expansion chamber.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of vehicle urea filler counter-jetting resistance structure, the counter-jetting resistance knot
Structure by central tube is set and regurgitate liquid storage cylinder storage filling finish jump rifle when filler and exhaust outlet regurgitate liquid, it is to avoid
Urea liquid regurgitates phenomenon, without individually arranging FLLV valves again, can not only reduce cost, moreover it is possible to reduce filler pipe peripheral component
Space-consuming, reduces arrangement difficulty.
What the present invention was realized in：A kind of vehicle urea filler counter-jetting resistance structure, including
One shell body；
One is sleeved on the central tube in shell body；
One exports the urea box interface for being connected and being connected with shell body sealed bottom with central tube；
One is connected with central tube import and with sealing the filler interface being connected at the top of shell body；
The shell body, central tube, urea box interface and filler Interference fit, which are surrounded, regurgitates liquid storage cylinder, is opened on the central tube
The steam vent of liquid storage cylinder is regurgitated provided with some be communicated to, also at least offering one on central tube is communicated to the row for regurgitating liquid storage cylinder
Liquid bath, the bottom level of the sump pit is not higher than the bottom for regurgitating liquid storage cylinder, and the shell is additionally provided with vitro to be communicated to instead
Spray the exhaust joint of liquid storage cylinder.
The shell body, central tube and urea box interface are integrally formed as an entirety.
A mistake proofing lasso is additionally provided between at the top of the filler interface and central tube.
The mistake proofing lasso is magnet.
The steam vent has five, the top of the circumferentially centrally disposed pipe of annular array of the steam vent described in five.
The sump pit is axially disposed strip slotted eye, and the axial length of sump pit is equal with regurgitating liquid storage cylinder.
Vehicle urea filler counter-jetting resistance structure of the present invention is finished by setting central tube and regurgitating liquid storage cylinder storage filling
Filler and exhaust outlet regurgitate liquid when jumping rifle, it is to avoid urea liquid regurgitates phenomenon, without again individually arrangement FLLV valves and
Other match somebody with somebody circuits, can not only reduce cost, moreover it is possible to reduce the space-consuming of filler pipe peripheral component, reduce arrangement difficult
Degree.
