Description of the drawings
Fig. 1 is anti-pulling oil filling pipe each section connection diagram in embodiment；
Fig. 2 is anti-pulling oil filling pipe Each part schematic diagram in embodiment.
Specific implementation mode
The utility model is described further with reference to specific embodiments and the drawings.
A kind of anti-pulling oil filling pipe is disclosed in conjunction with shown in Fig. 1 and Fig. 2, in embodiment, is mainly made of three parts, is respectively
The oil pipe 1 connected with refueling nozzle, the oil pipe 3 that independent switching oil pipe 2 is connected with fuel charger.
The end of oil pipe 1 and the front end of switching oil pipe 2 can be used snap fit and link together, in the prior art, clamping
It is to project the common installation method of part, this connection type difference is threadedly coupled, it can be automatic under larger stressing conditions
It is detached from, and simple installation, of low cost.It is easy for installation；Threaded connection can be used in the end of switching oil pipe 2 and the front end of oil pipe 3,
Have the advantages that connection fastening and easy to disassemble, maintenance, wherein 2 end of switching oil pipe is equivalent to nut, 3 front end of oil pipe is equivalent to
Bolt.
2 intracavitary of oil pipe of transferring has a check valve 4 and valve port 5, and check valve 4 can be by welding together sphere 41 and spring
42 are constituted, and the other end of spring 42 is welded on 2 intracavitary of oil pipe by holder 6, under normality, effect quilt of the sphere 41 because of spring 42
It heads into valve port 5 and mutually agrees with the inner wall of valve port 5, be similar to the one-way valve structures of automatic washing machine water pipe.
The end of oil pipe 1 can be interior mounted in the front end of switching oil pipe 2, and is fixed with the moderate mandril 7 of a length and (stretches out machine
Structure), can be specifically that one end is welded on 1 intracavitary of oil pipe by holder 8, the other end stretches out the copper coin of switching 2 certain distance of oil pipe
Mast can be open-top from valve port 5 by check valve 4 by mandril 7 after oil pipe 1 is connected with switching oil pipe 2, but not bullet
Spring 42 is pressed onto most short, and does not interfere flowing of the fuel oil inside pipeline.
If only transferring oil pipe 2 and the connection of oil pipe 3, when being full of the fuel oil of certain pressure in oil pipe, check valve 4 is in spring
Valve port 5 is fastened under force effect, oil will not leak；If oil pipe 1, switching oil pipe 2, oil pipe 3 are all connected with, the mandril 7 in oil pipe 1 will
Check valve 4 is open-top in switching oil pipe 2, and connecting the pressure oil in the oil pipe 3 of fuel charger can add by valve port 6 through the inflow of oil pipe 1
In oil gun.
Further, rubber washer 9 is there also is provided in 5 side of valve port, the port of it and oil pipe 1 is mutually agreed with, when 1 He of oil pipe
Switching oil pipe 2 can play the effect of sealing and anti-leakage oil when connecting.A circle card slot, rubber pad can be designed at the port of switching oil pipe 2
Circle 9 is not fixed, and may be stuck under normality in the card slot of switching oil pipe 2, when oil pipe 1 is inserted into, the port phase of rubber washer 9 and oil pipe 1
Agree with, to prevent leak-stopping oil.
As shown in Figure 1, the anti-pulling refueling nozzle adapter is in normal refuel, three parts are sequentially connected, and fuel oil connects certainly
The refueling nozzle that the fuel charger of oil pipe 3 flows into connected pipes 1 keeps system stable and reliable in work to form fuel flow path.If
Refueling nozzle is pulled by vehicle, and when pulling force is excessive, 1 end of oil pipe is automatically disengaged with 2 front end of switching oil pipe, plays protection oil pipe
The effect that will not be broken.At this point, mandril 7 exits the interaction with check valve 4 in oil pipe 1, check valve 4 is under spring force
Stifled to note valve port 5, the oil in oil pipe can not leak.It is connected using two-stage, it can also side if check valve 4 is faulty in switching oil pipe 2
Just it repairs, cost can be greatlyd save than replacing whole oil pipe.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
Novel technical solution and its inventive concept is subject to equivalent substitution or change, should all cover the scope of protection of the utility model it
It is interior.
