Description
Technical field
The utility model relates to a kind of auto parts and components, is specially a kind of Novel supercharger return tube, belongs to field of vehicle equipment.
Background technique
Present most EFI vehicle has return tube, at fuel pump fuel feeding to motor, form certain pressure except after the oil spout of normal supply fuel nozzle, remaining fuel oil sends back to fuel tank by return line, certainly the unnecessary gasoline vapor also having canister to collect also gets back to fuel tank by return tube, the pressure mediating gasoline can be played, can also oil consumption be reduced; In prior art, oil return pipe of supercharger and the many uses of pressurizer oil pipe flange are welded to connect, therefore pressurizer oil tube thickness be there are certain requirements so that weld, and oil return pipe of supercharger is connected with oil return pipe of supercharger flange welding, solder joint easily comes off, sealing is poor, oil return pipe of supercharger and pipe joint sealing structure simply, have the phenomenon of leakage of oil in addition.
Summary of the invention
The purpose of this utility model is just to provide a kind of Novel supercharger return tube to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of Novel supercharger return tube, comprise flange, oil pipe and pipe joint, it is characterized in that: one end adpting flange of oil pipe, the other end connecting tube joint of oil pipe, one end of oil pipe and Flange joint is provided with outside thread, internal thread is provided with in the hole of flange, and it is corresponding with the outside thread of oil pipe, oil pipe is connected by screw thread with flange, pipe joint is that one end inwall has circular groove and threaded body on the other end outer wall, and the one end with circular groove on pipe joint is connected with oil pipe.
Preferably, one end of described oil pipe and Flange joint is provided with outside thread, and outside thread is provided with a rubber layer.
Preferably, described oil pipe is connected by screw thread with flange, and the end face of the end face of oil pipe and flange is in same plane.
Preferably, the one end with circular groove on described pipe joint is connected with oil pipe, is provided with rubber sleeve in circular groove, and oil pipe is provided with the projection embedding and be closely connected with rubber sleeve in circular groove.
Preferably, described oil pipe is also provided with multistage bellows.
Compared with prior art, the beneficial effects of the utility model are: this pressurized machine oil pipe is reasonable in design, oil pipe is connected by screw thread with flange, and the end face of the end face of oil pipe and flange is in same plane, make pressurizer oil tube body and avoid between flange using the Placement of welding, there is not the situation that solder joint comes off, reliability is high, one end with circular groove on pipe joint is connected with oil pipe, rubber sleeve is provided with in circular groove, oil pipe is provided with the projection embedding and be closely connected with rubber sleeve in circular groove, rubber sleeve plays good sealing, well can prevent leakage of oil, reduce oily loss.

Fig. 3 is pipe joint sectional view described in model utility;
In figure: 1, flange, 2, oil pipe, 3, pipe joint, 4, rubber sleeve, 21, bellows and 22, rubber layer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, a kind of Novel supercharger return tube, comprise flange 1, oil pipe 2 and pipe joint 3, one end adpting flange 1 of oil pipe 2, the other end connecting tube joint 3 of oil pipe 2, one end that described oil pipe 2 is connected with flange 1 is provided with outside thread, and outside thread is provided with a rubber layer 22, achieve complete sealing state, prevent the phenomenon of leakage of oil, internal thread is provided with in the hole of flange 1, and it is corresponding with the outside thread of oil pipe 2, oil pipe 2 is connected by screw thread with flange 1, and the end face of the end face of oil pipe 2 and flange 1 is in same plane, make to avoid between pressurizer oil tube body with flange 1 using the Placement of welding, there is not the situation that solder joint comes off, reliability is high, pipe joint 3 has circular groove and threaded body on the other end outer wall for one end inwall, one end with circular groove on pipe joint 3 is connected with oil pipe 2, rubber sleeve 4 is provided with in circular groove, oil pipe 2 is provided with the projection embedding and be closely connected with rubber sleeve 4 in circular groove, rubber sleeve 4 plays good sealing, well can prevent leakage of oil, reduce oily loss, oil pipe 2 is also provided with multistage bellows 21, can compensate in return tube 2 tunnel because temperature and pressure fluctuates the axis caused, transverse direction and angular displacement, absorb the vibration deriving from engine system.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
