21, by the past and directly sealing valve body-side air flue 22, make spherical cavity be in sealing state, the air pressure in spherical cavity increases suddenly, left and right pressure
Difference increases, and rubber core 12 is so as to leaning on sealing valve side air flue 22.At this time at the left spherical cavity 25 of ball needle stand 7 and ball needle air flue 26
In open state, when inner gas pressure is higher than sphere air pressure, air just enters sphere by ball needle air flue 26, ball needle 9, such as blue
Ball, football, balloon, gas raft, lifebuoy etc., until sphere pressure reaches inflation and requires.
When the utility model is to tyre inflating, as shown in figure 4, being wrenched the valve inside that spanner 31 makes air inflation nozzle 34 clamp tire
36.Inflatable ball needle 9 is in normally open at this time, and tire direction is in sealing state.When starting to tyre inflating, ball
12 operation principle of core as described above, no longer repeat, 12 reliable ball sealer needle air flue 26 of rubber core, at valve body-side air flue 22 herein
In open state, when inner gas pressure is higher than tire pressure, air just passes through right spherical cavity 21, valve body-side air flue 22 and its subsequent
Air flue enters tire, until tire pressure reaches requirement.
In conclusion whether 9 direction of inflatable ball needle to ball inflating or 34 direction of air inflation nozzle to tyre inflating, only
It wants which direction to be connected with inflatable substrate, is just inflated from the trend direction, need not artificially manipulate and be selected.
The above, only one embodiment of the utility model, not makes in any form the utility model
Limitation, on the basis of not departing from the technical solution of the utility model, made simple modification, equivalent variations or modification are fallen
Enter the scope of protection of the utility model.
