Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Embodiment 1
Oil filling pipe for automobiles assembly shown in Fig. 1 comprises oiling tube 1 for refueling to fuel tank 3 and the breather pipe 2 in order to keep the barometric pressure inside and outside fuel tank 3 consistent, oiling tube 1 is metal tube or plastic pipe, breather pipe 2 is the flexible hoses be made of plastics, oiling tube 1 and breather pipe 2 all have one end to be connected with fuel tank 3 respectively, the other end of breather pipe 2 is connected to oiling tube 1 outer wall nearly pouring orifice 1-1 place, the two ends of breather pipe are connected as the vent joint of sealing member with the vent joint on the oiling tube of metal and fuel tank respectively by rubber coating 7, and by the fastening (see figure 2) of elasticity pipe collar 6.This breather pipe 2 has bellows piece 2-1 and more piece spaced tubular pipeline section 2-2, tubular pipeline section 2-2 radially outward protrudes from bellows piece 2-1, the internal diameter of tubular pipeline section 2-2 is greater than the internal diameter of bellows piece 2-1, thus make breather pipe 2 form the body with the more piece deformation variable-section tubular of collection chamber, collection chamber is formed in tubular pipeline section 2-2, the fluted 2-21 of spiral surrounding on the outer wall of tubular pipeline section 2-2, part corresponding with groove 2-21 on inwall is swelled and is formed spirality convex rib in collection chamber.
This oil filling pipe for automobiles assembly in use, when oiling will be expired, the air being in fuel tank 3 internal upper part sweeps along a small amount of fuel oil to discharge from breather pipe 2, the passage section sudden change that collection chamber causes makes rate of flow of fluid suddenly change, namely fluid is when the tubular pipeline section 2-2 that the bellows piece 2-1 inflow diameter less from diameter is larger, and the unexpected change of gas channel causes greatly rate of flow of fluid to reduce suddenly; When the tubular pipeline section 2-2 larger from diameter enters the less bellows piece 2-1 of diameter, diminishing suddenly of gas channel causes flow velocity to increase suddenly.Fuel oil is large and delayed because of its inertia ratio air, causes the two to be separated thus.In addition, spirality convex rib on the rough inwall of bellows piece 2-1, collection chamber wall all increases the resistance of the flowing to liquid fuel, enhance the wall attachment effect of fluid, thus make fuel oil separated from the gas further, problem regurgitated by fuel oil when efficiently solving oiling.
Embodiment 2
As shown in Figure 2, in two tubular pipeline sections 4 at breather pipe two ends, loose oily device 5 is all being housed respectively, loose oily device 5 for one end close, the cone-shaped and thin-walled part of other end opening, cone-shaped and thin-walled part has a taper sheath 5-2, the small end of taper sheath 5-2 is linked with a hollow cylinder 5-1, the free end sealing of hollow cylinder 5-1, and the large end of taper sheath 5-2 is linked with the spaced curved 5-3 of multi-disc, curved 5-3 is arranged, see Fig. 3 around the line of centers circular array of taper sheath; The outer side edges of curved 5 extends to the position near tubular pipeline section 4 inwall along the plain line direction of taper sheath 5-2, then the formation limiting section that bends inwards; Cone-shaped and thin-walled part is made of plastics, and can produce elastic deformation, is beneficial to enter in the collection chamber of head and the tail two tubular pipeline sections by the less port of diameter and the bellows piece that is connected with port; The inwall that the tubular pipeline section 4 of loose oily device 5 is housed is provided with 4 annular convex rib 4-1, when loading loose oily device 5, draw curved in centre to put into breather pipe, when loose oily device 5 enters after collection chamber elasticity returns to normality, the limiting section of curved 5-3 is stuck between middle two annular convex rib 4-1.All the other features are identical with embodiment 1.During work, gas mixture enters after breather pipe encounters loose oily device 5, fuel oil sticked to the circular conical surface of taper sheath 5-2 by dispersion and curved 5-3 upper or reflex on collection chamber wall, the annular convex rib 4-1 on collection chamber wall strengthens oily wall attachment effect; The gap of loose oily device 5 greatly between each curved 5-3 of end can allow gas pass through smoothly, then plays inhibition to fluid, Oil-gas Separation can be made thus more thorough, more effectively solve and regurgitate problem.
Embodiment 3
Tubular pipeline section 8 inwall of the breather pipe shown in Fig. 4 is provided with spiral groove 8-1, respectively loose oily device is all being housed in the collection chamber of two tubular pipeline sections 8 at breather pipe two ends, described loose oily device is that helical sheet 9 is made of plastics along tubular pipeline section axially extended helical sheet 9.All the other features are identical with embodiment 1.During work, can produce rotational flow at a relatively high speed when gas mixture flows through helical sheet 9, turbulent flowization and centrifugal effect make gas along inside spiral rising flowing, and the liquid that density is larger then along flows outside or can be thrown on tube wall, thus makes Oil-gas Separation.Fuel oil after separation is trapped in breather pipe and flows back to fuel tank, and air is discharged from oiling tube oral area, eliminates the phenomenon that fuel oil is regurgitated.
