Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
Embodiment shall fall within the protection scope of the present invention.
A kind of charging valve external member, including charging valve and filling gun two parts match when filling operation, add
Note valve is installed on the equipment for needing fueling, and filling gun is installed or is matched on the filing provision of ground.
As shown in Fig. 2, charging valve includes valve body 12, valve body left end is flange arrangement, with fuel oil tank phase
Even, it is exported as charging valve, for valve body right end as charging valve entrance, valve body 12 is interior to be equipped with mandril 13 and valve
One end of spring base 15, mandril 13 is threadedly coupled with valve body 12, and mandril 13 is locked at valve by valve nut 11
On shell 12, the other end of mandril 13 is protruded into shutter spring seat 15, is equipped with and is lived between valve body 12 and shutter spring seat 15
Door spring 4, the outside of shutter spring seat 15 are equipped with the O-ring VIII19 with the sealing cooperation of valve body 12, and mandril 13 is equipped with
The O-ring I16 cooperated with the inner seal of shutter spring seat 15, shutter spring seat 15 are equipped with the gate hole for circulation.Valve
Shell 12 is equipped with connects slot fastly, and the lock section for connecting slot and blocking 17 fastly cooperates, and blocking 17 is equipped with to be cooperated with the filling sealing of shell 12
O-ring II18.
Under non-filling state, shutter spring seat 15 is moved right by the effect of shutter spring 14, while by 13 upper limit of mandril
The effect of position portion reaches its limit of sports record position, and blocking 17 moves right under the effect of shutter spring seat 15, lock section at circumferential two
Connected slot limit fastly by valve body, reach capacity position.Mandril 13, valve body 12, shutter spring when in the state
Radial seal is realized by O-ring between seat 15 and blocking 17, to guarantee that fuel oil tank is isolated from the outside world in this state, reaches
To sealing effect.
As shown in figure 3, filling gun includes transfer block 23, transfer block 23 is three-port structure, and one end is standard interface, with ground
Equipment is connected, and as fuel filler, one end is threadedly coupled with blanking cover 21, is cooperated by O-ring III22 and realizes blanking cover 21 and switching
Block 23 it is long when seal, other end will transfer by bearing 212 and 24 rotatable engagement of adapter, and by locking nut 213
First 24 connect with bearing 212, while blanking cover 21 holds out against bearing 212, position to bearing 212, so that it is guaranteed that adapter is fixed
In transfer block, and it can be rotated freely along 360 ° of adapter axis.Fuel oil can enter it by the gate hole on 24 conical surface of adapter
Inside runner, cooperated between transfer block 23 and adapter 24 by being sealed with O-ring IV25, realizes point of runner and free surrounding space
From guarantee fuel oil runner sealing.24 other end of adapter is connect by screw thread with filling shell 27, and the two passes through O-ring V26
Realize sealing.It fills and is equipped with filling spool 211 in shell 27, filling spring 28 is equipped between adapter 24 and filling spool 211,
It fills shell 27 and is equipped with the O-ring VI29 cooperated with the sealing of valve body 12.
Under non-filling state, filling spool 211 is moved under the action of filling spring 28 to exit end, until its limit
When position, the axial seal face on spool and filling housing bottom R face contact are filled, forms sealing pair at one, in addition fill valve
O-ring VII210 and filling shell on core cooperatively form sealing pair at second, to realize the double sealing structure at this, it is ensured that
Filling gun can be safer and more reliable in discrete state seal performance.Filling gun sealing surface uses double sealing structure, in therein
Pressure effect is lower to have good sealing performance, good reliability, safety coefficient height；Filling gun pipette tips and filling gun Ground Service Plug can
It realizes 360 ° to rotate freely, convenient for docking with charging valve；Filling gun and charging valve can keep good in docking operation
Self-sealing state, fuel leakage can be effectively prevent.
As shown in figure 4, charging valve and filling gun are that rotary plug-in type links structure fastly, valve body 12 is equipped with connects slot fastly, adds
It infuses shell 27 and is equipped with lock pin, lock pin cooperates with slot is connected fastly.
Charging valve and filling gun are in self-sealing state in undocked state, after charging valve is connected with filling gun
Respective valve is automatically opened, fuel can be made to pass through, and to external seal, fuel is avoided to generate leakage；Charging valve and plus
Restore self-sealing state automatically again after infusing rifle separation.
As shown in Figure 1, mandril 13 and valve body 12 are fixed, therefore it is constant with valve body relative position, fills spool
211 can be free to slide in filling shell 27.When docking, filling gun is directly docked with charging valve first, charging valve enters
Mouth connects slot with guiding role fastly, facilitates filling gun automatic capturing docking location.Under external force, mandril 13 overcomes filling
The spring force of spring 28, the spring force of shutter spring 24 and O-ring frictional force open filling spool 211, and filling spool moves back,
O-ring VIII19 and O-ring VI29 moment keep good sealing effectiveness during being somebody's turn to do, and can effectively prevent docking operation intermediate fuel oil
Leakage realizes that filling gun is communicated with charging valve runner until mandril 13 will fill spool 211 and open to shown position.At this time
Locking pin on filling shell 27 while the position that reaches capacity, can be manually rotated about 45 ° of shell of filling, screw in locking pin and live
Connecting in slot in gate housing 14 fastly realize the locking to filling gun.
The docking of charging valve external member is completed, and medium channel is opened, and quick-connect mechanism locks both ends, is allowed to use process
In will not separate；When the separation of charging valve external member, filling gun is first pushed down on to extreme position, then can be manually rotated filling shell
It about 45 ° of body, exits the locking pin on shell on valve body and connects slot fastly, release the lock state of charging valve external member,
Filling gun and charging valve fill spool and shutter spring seat are retracted respectively respectively under the action of filling spring and shutter spring
The self-sealing of two components is realized in home position again.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
