Abstract
The utility model discloses an oiling pipeline of a passenger car, which comprises an inlet section, a straight tube section and an outlet section which are sequentially communicated. The inner diameter of the inlet section is larger than the inner diameter of the straight tube section and the inner diameter of the outlet section, small holes (1-1) are arranged on the lateral wall of the inlet section, bent sections with the radius of R are arranged at one ends of the outlet section connected with the straight tube section, and 90mm<=R<=200mm. The oiling pipeline of the passenger car is simple in structure, leads oil to be effectively guided in flowing direction and reduces resistance of oil flowing.
Description
Technical field
The utility model relates to a kind of passenger car oil filling pipe assembly, is specifically related to the oiling pipeline of oil filling pipe assembly.
Background technique
The fuel filling of vehicle is the fuel tank that fuel oil is filled into vehicle through nozzle by Equipment In Oil Service Station; But on most of passenger car; Because the restriction of spatial arrangement, fuel oil can not directly get into fuel tank through nozzle, but pipeline is laggard goes into fuel tank through refueling.
Because it is the same big with the internal diameter at other positions that existing passenger car refuels the entrance internal diameter of pipeline, do not design flow guide structure or flow guide structure is bad yet, when causing fuel filling, fuel flow has some setbacks, and just can occur splash during filling or gushs beyond the fuel pipe; Or fuel oil do not reach before the specified adding amount frequent the jumping and robs (being to stop automatically refueling after fuel oil can not smooth and easy inflow fuel tank causes fuel level to rise flooding the vent on the nozzle) and cause refueling time long, and operation frequently.
Summary of the invention
The purpose of the utility model provides a kind of passenger car oiling pipeline, and it is simple in structure, can make fluid can access effective flow direction guiding, reduce the resistance that fluid flows.
The described a kind of passenger car of the utility model refuels pipeline, comprises entrance, straight length and the outlet section of UNICOM successively, it is characterized in that: the internal diameter of said entrance is both greater than the internal diameter of straight length, again greater than the internal diameter of outlet section; On the sidewall of said entrance, be provided with an aperture, so that the gas in the fuel tank is discharged near oral area.
Further, the connection part of said outlet section and straight length is one section swan-neck, and the swan-neck radius R is 90-200mm.
Further, the length L of said straight length is 100-150mm.Avoiding fuel oil get into to refuel direct collision behind the pipeline refuels on the tube wall of pipeline.
The utility model compared with prior art has the following advantages: it is simple in structure; Can make fluid effectively flowed to guiding, reduce the resistance that fluid flows; Avoid splash, gush and fuel oil does not reach that the frequent phenomenon of robbing of jumping takes place before the specified adding amount, guarantee that fluid gets into fuel tank smoothly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of passenger car oiling pipeline as shown in Figure 1 comprises entrance 1, straight length 2 and the outlet section 3 of UNICOM successively; The internal diameter of said entrance 1 is both greater than the internal diameter of straight length 2, again greater than the internal diameter of outlet section 3; On the sidewall of said entrance 1, be provided with an aperture 1-1, so that the gas in the fuel tank is discharged near oral area.
Further, said outlet section 3 is one section swan-neck with the connection part of straight length 2, and the swan-neck radius R is 90 mm, to reduce fuel flow ground resistance, guarantees that fluid flows into fuel tank swimmingly.
Further, the length L of said straight length 2 is 100mm, refuels on the tube wall of pipeline to avoid fuel oil get into to refuel direct collision behind the pipeline.
Entrance 1 internal diameter is convenient to stretching into of nozzle greater than the external diameter of nozzle.
The length of said straight length 2 also can be 130mm or 150mm; The connection part of said outlet section 3 and straight length 2 is that the radius R of one section swan-neck also can be 150m or 200mm.
Claims (3)
1. a passenger car refuels pipeline, comprises the entrance of UNICOM (1), straight length (2) and outlet section (3) successively, it is characterized in that: the internal diameter of said entrance (1) is both greater than the internal diameter of straight length (2), again greater than the internal diameter of outlet section (3); On the sidewall of said entrance (1), be provided with an aperture (1-1) near oral area.
2. a kind of passenger car oiling pipeline according to claim 1, it is characterized in that: said outlet section (3) is one section swan-neck with the connection part of straight length (2), and the swan-neck radius R is 90-200mm.
