Separator 2 is the cylinder of both ends open, and through-hole is uniformly provided on the side wall of separator 2, is equipped in through-hole
Diameter is greater than the steel ball 5 of via depth, and corking 1 is sleeved in separator 2, positioned at one end of separator 2, corking 1 and separator 2
On be provided with limited step；
It adjusts plug screw 8 to be threadedly secured in the other end of separator 2, be equipped between corking 1 and adjusting plug screw 8
Corking spring 4；
Groove is provided on the side end face of corking 1, the distance of 2 outer wall of separator to bottom portion of groove is greater than the diameter of steel ball 5, recessed
Slot position is in the surface of steel ball 5；
The upper end of 10 bar of valve is threaded and is set with steel ball lock spring 9, and the rod set of valve 10 is mounted in adjusting plug screw 8
Hole in, and can be slided up and down in hole, the top for adjusting 8 inner hole of plug screw is provided with limited step, passes through nut 6 and washer 7 will
Upper end, which is limited to, to be adjusted in plug screw 8；
Sealing ring 3 is installed between the outer end face of separator 2, the outer end face of valve 10 and separator 2 and corking 1.
As a kind of improvement of the technical program, it is fixed with safety loop 11 in the lower end of valve 10, and solid by chain 12
It is scheduled on body structure.
The invention has the benefit that engaging of the steel ball with lid mounting base keeps the locking function of lid more reliable；It adopts
Realize the quick on and off of filler cap with push type method, it is easy to operate, working service is good；It is adjusted by rotation
The pressing force of the adjustable valve of plug screw, meets the different required sealed pressure requirements of fuel tank, and generalization degree is high.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is A-A cross-sectional view；
Fig. 3 is part drawing of the invention；
Wherein, 1- corking, 2- separator, 3- sealing ring, 4- corking spring, 5- steel ball, 6- nut, 7- washer,
8- adjusts plug screw, 9- steel ball locks spring, 10- valve, 11- safety loop, 12- chain.
Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing:
Please refer to Fig. 1, Fig. 2 and Fig. 3, wherein Fig. 1 is a kind of outline drawing of quick-release type lid of the present invention, and Fig. 2 is Fig. 1
A-A cross-sectional view, Fig. 3 are the exploded views of Fig. 1 main component.In present embodiment, the adjustable quick-release lid of the aircraft refuelling
Including corking 1, separator 2, sealing ring 3, corking spring 4, steel ball 5, nut 6, washer 7 adjust plug screw 8, steel ball lock spring 9,
Valve 10, safety loop 11, chain 12.
Separator 2 is the cylinder of both ends open, is uniformly opened on the side wall of separator 2 there are four through-hole, and through-hole is interior to pacify
Be greater than the steel ball 5 of via depth equipped with diameter, corking 1 is sleeved in separator 2, positioned at one end of separator 2, corking 1 and point
From being provided with limited step on device 2.
It adjusts plug screw 8 to be threadedly secured in the other end of separator 2, be equipped between corking 1 and adjusting plug screw 8
Corking spring 4, by pressing, corking can slide up and down between plug screw 8 and limited step adjusting.
Groove is provided on the side end face of corking 1, the distance of 2 outer wall of separator to bottom portion of groove is greater than the diameter of steel ball 5, recessed
