Model utility content
The technical problems to be solved in the utility model is to provide a kind of in inflation with can guarantee that the restriction that gas circuit is unimpeded fills cylinder valve during with gas.
For solving the problems of the technologies described above adopted technological scheme: a kind of restriction fills cylinder valve, include cylinder valve, it is characterized in that: the fixing seat of honour and lower are installed in the valve opening of described cylinder valve, in valve opening between the seat of honour and lower, be provided with active base rotatable and that slide up and down, the seat of honour, lower and active base all offer through hole, fix the permanent magnet of an eccentric setting in active base; If a fixing magnetic part, this magnetic part coordinates to drive active base to rotate with permanent magnet, makes the active base through hole lower block hole that staggers; If an elastic member, this elastic member drives active base to slip away lower.
On the basis of the above, described magnetic part is fixed on lower; If a central shaft, the two ends up and down of central shaft are inserted into respectively in active base and lower.
On the basis of the above, described elastic member is Compress Spring, and Compress Spring is arranged between central shaft and lower central shaft jack-up; The opposite side at active base and the seat of honour is formed with respectively the dead axle portion of concave-convex.
The beneficial effect that adopts the utility model to bring: the utility model adopts the active base of fixing eccentric permanent magnet to open and close the gas circuit of cylinder valve, during inflation, identifier on charge gun has been identified after steel cylinder sign, start electromagnetic generator, produce electromagnetic force, the magneto drive active base that electromagnetic force overcomes between magnetic part and permanent magnet is rotated, and active base and lower the through hole originally staggering are aligned, form straight-through gas circuit, while having guaranteed inflation, gas circuit is unimpeded.The steel cylinder of None-identified cannot start electromagnetic generator and drive active base to rotate, and the elastic force that inflation pressure can press active base to overcome elastic member slides to lower, active base that through hole staggers and lower are close to, thereby the gas circuit of closing cannot be inflated.While using gas, active base, under the elastic force effect of elastic member, remains and leaves a lower certain distance, between active base and lower, forms passage, makes active base and lower the through hole staggering by channel connection, forms the unimpeded gas circuit with gas.Visible, the gas circuit while adopting the utility model can guarantee cylinder valve in inflation with gas is unimpeded.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model restriction fills cylinder valve.
Embodiment
As shown in Figure 1, a kind of restriction fills cylinder valve, include cylinder valve 1, the fixing seat of honour 2 and lower 3 are installed in the valve opening 1.1 of described cylinder valve 1, the perisporium of lower seat 3 and the inwall of valve opening 1.1 are close to sealing, in valve 1.1 holes between the seat of honour 2 and lower 3, be provided with active base 4 rotatable and that slide up and down, the seat of honour 2, lower 3 and active base 4 all offer through hole, fix the permanent magnet 5 of an eccentric setting in active base 4.If a fixing magnetic part 6, this magnetic part 6 and permanent magnet 5 coordinate to drive active base 4 to rotate, and make the active base through hole 4.1 lower block hole 3.1 that staggers.If an elastic member, this elastic member drives active base 4 to slip away lower 3.Active base 4, under the elastic force effect of elastic member, remains and leaves lower 3 certain distances, between active base 4 and lower 3, forms passage 7, and active base 4 is communicated with by passage 7 with lower 3 through holes that stagger completely, forms the unimpeded gas circuit with gas.During inflation, identifier on charge gun has been identified after steel cylinder sign, start electromagnetic generator, produce electromagnetic force, the magneto drive active base 4 that electromagnetic force overcomes between magnetic part 6 and permanent magnet 5 is rotated, active base 4 and lower 3 through hole originally staggering are aligned, form straight-through gas circuit, while having guaranteed inflation, gas circuit is unimpeded.The steel cylinder of None-identified cannot start electromagnetic generator and drive active base 4 to rotate, the elastic force that inflation pressure can press active base 4 to overcome elastic member slides to lower 3, the active base 4 that through hole staggers is completely close to lower 3, thereby the gas circuit of closing cannot be inflated.
