Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
It is as shown in Figures 1 to 5 the structural schematic diagram of the utility model,
Appended drawing reference therein are as follows: oiling steel pipe 1, flared section 21, screw thread 21a, tooth circle 21b, crimping 22, follows at oil filler 2
Ring snorkel 3, the first fast interpolating unit 31, first annular retaining ring 32, throttle valve 4, canister vent pipe 5, the second fast interpolating unit 51, the second ring
The fixed bracket 62 of the fixed bracket 61, second of shape retaining ring 52, first, the fixed bracket 64 of the fixed bracket the 63, the 4th of third.
As shown in Figures 1 to 5,
A kind of oil gas recoverable version automobile fuel filler pipe assembly, including oiling steel pipe 1 and oil filler 2, oiling steel pipe 1 and oiling
Mouth 2 is welded and fixed, and the circulation ventilating pipe 3 that outer diameter is 8mm, internal diameter is 6.6mm is connected on oil filler 2, is set in circulation ventilating pipe 3
It is equipped with the throttle valve 4 that orifice diameter is 2mm, the tail end of circulation ventilating pipe 3 is provided with the first fast interpolating unit 31 to contract, adds
1 one end of oiling steel pipe is provided with flared section 21 on hydraulic fluid port 2, screw thread compatible with fuel tank cap is provided in the flared section 21
21a, oil filler 2 is interior to be provided with tooth circle 21b on the inside of screw thread 21a；Canister vent pipe 5, canister vent are fixed with by oiling steel pipe 1
The tail end of pipe 5 is provided with the second fast interpolating unit 51 to contract.
The effect of tooth circle 21b, can be such that refueling nozzle is more smoothly inserted into oil filling pipe, and after hand leaves oil gun, very
Facilitate and oil gun is tangled.
In embodiment, the turned-out volume in the end of oil filler 2 forms crimping 22.
In embodiment, the tail portion of circulation ventilating pipe 3 is provided with first annular retaining ring 32.
In embodiment, the tail portion of canister vent pipe 5 is provided with the second annular retaining ring 52.
First annular retaining ring 32 and the second annular retaining ring 52 play position-limiting action, limit circulation ventilating pipe 3 and carbon respectively
The insertion depth of 5 tail end of tank snorkel.
In embodiment, it is fixed that the first fixed bracket 61 and second is welded between oiling steel pipe 1 and circulation ventilating pipe 3
Bracket 62.
In embodiment, oiling steel pipe 1, circulation ventilating pipe 3 and canister vent pipe 5 are fixed by the fixed bracket 63 of third.
In embodiment, the tail portion of circulation ventilating pipe 3 and the tail portion of canister vent pipe 5 are fixed by the 4th fixed bracket 64.
The oil filling pipe of the utility model, oil filler 2 and oiling steel pipe 1 are using being welded and fixed, and oil filler 2 is using flaring work
Skill forms flared section 21 and matches with oil filler, and forms crimping 22 in the turned-out volume in end, utilizes the circular arc and oil of crimping 22
The sealing ring of case lid matches, and improves leakproofness.
The effect of circulation ventilating pipe 3 be refuel when in fuel tank gas and pressure be transported to out of fuel tank oil filling pipe expand
It is still transported to fuel tank, gas and pressure in fuel tank is made to reach flat by mouthful position, the negative pressure generated when oil stream is dynamic when oiling
Weighing apparatus；It is smooth to make to refuel, it prevents from jumping rifle.
Circulation ventilating pipe 3 inserts needs to meet the fast of the fast interpolating unit 31 in tail portion first, uses the outer diameter to be for 8mm, internal diameter
The metal tube of 6.6mm, the large diameter of circulation ventilating pipe 3 cause ventilation flow rate big, and big flow will lead at oil filling pipe flaring
Oil vapour can not be all introduced into fuel tank, it can go to gas in atmosphere from the gap of refueling nozzle and oil filler, cause to refuel
Discharge is not up to standard when pipe refuels, unqualified, also pollutes environment, therefore throttle valve 4 is arranged to reduce its stream in circulation ventilating pipe 3
Amount, so that the oil vapour reduced in fuel tank enters at oil filling pipe flaring.But the throttle orifice internal diameter of throttle valve 4 can not be too
It is small, if aperture is too small, oil-feed tank can be sucked from a large amount of air when oiling, and the gas output of canister be it is constant, in this way
Pressure in fuel tank can become larger and cause to jump rifle.
The tail end of circulation ventilating pipe 3 and canister vent pipe 5 uses fast inserting structure (the first fast interpolating unit 31, the second fast interpolating unit 51)
It is connect with fuel tank, the discharge of hydrocarbon molecules can be reduced.
The oil filling pipe of the utility model can be realized petroleum vapor recovery, and can effectively reduce the discharge of hydrocarbon molecules, meet
Six standard of state.
The most preferred embodiment of the utility model has illustrated, the various change or remodeling made by those of ordinary skill in the art
All without departing from the scope of the utility model.
