Gas cylinder valve provided by the present invention, is internally provided with the first spring 2 and can be along the valve element of the axial movement of valve body 1
Portion, due to the supporting role of the first spring 2, has gap between the lower end in valve element portion and valve port 12.When being inflated to gas cylinder
When, this valve element portion is subject to the thrust of air inlet, and overcomes the elastic force of the first spring to move down to block valve port 12, from
And block this gas replenishment process.And the stop part within when valve body 1 is controlled and when being in extended position, stop part then can be with valve element
Conflicting in the axial direction in portion, is moved to valve port with limiting valve element portion, so that depositing all the time between the lower end in valve element portion and valve port 12
In gap so that inflation is carried out.
In the specific implementation, the label of gas cylinder body can first be identified using charge gun, to judge whether gas cylinder is qualified.If should
Gas cylinder is qualified, then this charge gun can produce suitable electromagnetic force to drive stop part to be in extended position, and then limits valve element portion
Axial displacement, thus being inflated to gas cylinder；If this gas cylinder is unqualified, charge gun does not produce electromagnetic force, and stop part is in former

So, by the cooperation of charge gun and gas cylinder valve provided by the present invention, can fundamentally prevent to scrap examination
Test with gas cylinder, the reusing of gas for domestic use bottle, and exclude the phenomenon of non-fixed point inflation, thus user can farthest be ensured
The person and property safety.
It should be appreciated that in unaerated, the first spring 2 in order to support valve element portion may be at compressive state it is also possible to
It is in extended state.Specifically, due to the effect of valve element portion self gravitation, when the first spring 2 is in valve element portion and valve port 12
Between when, the first spring 2 will be in compressive state；And when the first spring 2 is between valve element portion and air inlet, the first spring
2 will be in extended state.When stop part is not in extended position, the inflation behavior to gas cylinder will further aggravate the first bullet
Spring 2 state in which, and make the bottom in valve element portion block valve port 12, now, when the behavior of inflation stops, in the first spring
In the presence of 2 elastic force, valve element portion quick recoverable is to reset condition.
Specifically, still as shown in figure 1, valve element portion can include valve rod 4, now, the upper end of the first spring 2, lower end are permissible
It is connected to periphery, the inwall of valve body 1 of valve rod 4 respectively.When stop part is in home position, under the thrust of air inlet,
The bottom of valve rod 4 can cooperatively form sealing with valve port 12, to block gas replenishment process.
Above-mentioned valve element portion can also include the valve element 3 between valve rod 4 and the first spring 2, and valve element 3 is interior with valve body 1
Wall slides axially sealing.Valve element 3 is provided with passage 31, and to connect air inlet and valve port 12, the bottom of valve rod 4 can be logical with this
Pore 31 fitted seal.
Using said structure, valve rod 4 will not directly be contacted with the first spring 2, in the presence of valve rod 4 self gravitation,
The bottom of valve rod 4 is blocked passage 31 naturally.When being inflated to gas cylinder, gas will force valve rod 4 and valve element 3 synchronous
Generation moves down, and in the process, valve rod 4 is plugged in passage 31 all the time, causes gas replenishment process to be difficult to；At stop part
When extended position, the axial displacement of valve rod 4 will be limited, now, then when this gas cylinder is inflated, gas will only promote above-mentioned
Valve element 3 moves down, so that the bottom of valve rod 4 departs from this air-vent 31, and then gas replenishment process is carried out.
For the structure directly abutting against with valve rod 4 than the first spring 2, the structure that above-mentioned valve element 3 is matched with valve rod 4
It is more beneficial for ensureing the closing of the internal inlet channel of valve body 1, as long as stop part is not in extended position, the bottom of valve rod 4
The passage 31 of valve element 3 can be plugged in all the time, and without treating the pressure of inflatable body, thus further preventing from scrapping
The reusing of gas cylinder, and exclude the phenomenon of non-fixed point inflation；It is to be understood that, when only arranging valve rod 4, structure is more simple, peace
Fill more convenient.
Again as shown in Fig. 2 the passage 31 of above-mentioned valve element 3 can be shoulder hole, this shoulder hole can include from top to bottom
Large diameter hole and diameter holes.In concrete installation, large diameter hole can first be inserted in the bottom of valve rod 4, due to large diameter hole aperture relatively
Greatly, differ less with the internal diameter of valve body 1, valve rod 4 of being more convenient for positions the position of passage 31；Then, valve rod 4 is inserted into diameter holes
And block this diameter holes, because the aperture of this diameter holes is less, the bottom of valve rod 4 of being more convenient for blocks to it.Above-mentioned logical
Pore 31 can also be isometrical hole, and during use, the bottom of valve rod 4 can directly block the top in this isometrical hole, and it is right also to can achieve
The closing of inlet channel in valve body 1.
With Fig. 3 as visual angle, the bottom of above-mentioned valve rod 4 can be globular part 41, and the upper end of valve rod 4 is provided with and radially extends
Extension 42.When mounted, when globular part 41 is plugged in above-mentioned diameter holes, extension 42 is higher than the upper end of above-mentioned large diameter hole
Face, so, the upper surface of the lower surface of extension 42 and valve element 3 can self-assembling formation draw-in groove, when stop part is in extended position,
Stop part can be inserted in this draw-in groove.When gas cylinder is inflated, the gas being filled with from air inlet can promote valve element 3 and valve rod 4
Move down, now, stop part can be resisted against the lower surface of extension 42, and then the axial displacement of restriction valve rod 4, and makes globular part
41 are separated with diameter holes, so that inflation is carried out.
It should be noted that the structure design of above-mentioned valve rod 4 is only a kind of preferred version of the embodiment of the present invention, can not
As the restriction of the scope of the present invention, on the premise of not affecting function of the present invention, above-mentioned valve rod 4 may be designed in other
Form.For example, the upper end of this valve rod 4 can also be provided with hole clipping, when stop part is in extended position, the inner of this stop part
Portion can be plugged in hole clipping, to limit the axial displacement of valve rod 4；The bottom of valve rod 4 can also be tapered rod, this tapered rod
The external diameter on top is more than the internal diameter of above-mentioned diameter holes, and now, this tapered rod can also be plugged in this diameter holes.
Further, as shown in Fig. 2 the large diameter hole of above-mentioned passage 31 and diameter holes can also be connected by taper seat,
The radial dimension of taper seat is gradually reduced from top to bottom, refer to Fig. 2, and that is, the step surface between large diameter hole and diameter holes is recessed
The conical surface, so, after globular part 41 insertion large diameter hole, this conical surface can play the guiding role to globular part 41, so that this globular part
41 can block above-mentioned diameter holes naturally, and installation process is more simple.
Based on this, the structure of above-mentioned passage 31 can be improved further, for example, above-mentioned diameter holes also can be designed
For the diminishing bellmouth of internal diameter from top to bottom, so, the inwall of this diameter holes can play guiding and make to this globular part 41
With so that this globular part 41 is connected in diameter holes naturally, and then blocking this diameter holes；Or, also can be by above-mentioned passage 31
Global design is recessed bellmouth, so, when above-mentioned globular part 41 inserts this passage 31, can be directly along along bellmouth
Wall naturally moves down and blocks this passage 31.
Still with Fig. 3 as visual angle, the upper sphere of above-mentioned globular part 41 also can be provided with some guide tabs radially extending
43, when globular part 41 is plugged in diameter holes, the outer rim of each guide tabs 43 can be fitted with the internal perisporium of large diameter hole, thus
Valve rod 4 is steadily placed in this large diameter hole.Especially when stop part is driven and extend out to extended position by external force, valve rod
4 still can keep vertical state after the shock by stop part, so that stop part can stably be resisted against the lower end of extension 42
Face, and then limit the length travel of valve rod 4.
On the other hand, when globular part 41 is plugged in diameter holes, between this globular part 41 and above-mentioned large diameter hole inwall between
Gap is divided into multiple narrow and small air flues by each guide tabs 43.When stop part is in extended position to limit longitudinal position of valve rod 4
During shifting, the gas entering from air inlet can obtain higher speed in each air flue, thus possessing higher impulsive force to compel
So that valve element 3 is moved down rapidly, and so that globular part 41 is departed from this diameter holes, to be quickly inflated.
It is pointed out that the above-mentioned outer rim of each guide tabs 43 and the internal perisporium of large diameter hole fit should be understood to greatly
Cause laminating, on the premise of not affecting each guide tabs 43 function, the outer rim of each guide tabs 43 and the internal perisporium of large diameter hole it
Between there may be certain gap.
Still with Fig. 1 as visual angle, the side wall of above-mentioned valve body 1 can arrange laterally extending extension section 13, above-mentioned stop part bag
Include slide 5 and slide block 6, the outer end of slide 5 and extension section 13 circumferential seal, to ensure the sealing of extension section 13, slide 5
Inner end is inside extension section 13, and slides laterally with slide block 6 and be connected.So, apply electromagnetic force in the periphery of epitaxy part 13
When, slide block 6 can slide laterally along slide 5, and then is conflicted, in the axial direction to limit valve in the inner end of slide block 6 and valve element portion
Core moves to valve port.
Specifically, as shown in figure 5, the inner end of slide block 6 is also provided with raised 61, when stop part is in extended position
When, this projection 61 can be connected to the lower surface of extension 42.It should be appreciated that raised 61 radial dimension is less than the external diameter of slide block 6,
When using, the little projection of radial dimension 61 is more easy to be connected to the lower surface of extension 42.
Slide block 6 can be with overcoat second spring 7, and the two ends of second spring 7 are connected to periphery and the extension of slide block 6 respectively
The inwall of section 13.When the periphery of extension section 13 does not have electromagnetic force, due to the supporting role of second spring 7, slide block 6 can be made
Stably it is in home position；And after applying suitable electromagnetic force, the inner end of slide block 6 can slide laterally to the left, and abuts
In the displacement to limit valve rod 4 for the lower surface of extension 43, now, if the electromagnetic force putting on extension section 13 periphery disappears,
In the presence of second spring 7, slide block 6 can return back to home position in time, and then cancels spacing to valve rod 4, so, treats next time
During inflation, valve rod 4 still can stop the carrying out of this gas replenishment process.It should be appreciated that when slide block 6 stretches out to abut the following table of extension 43
During face, second spring 7 may be at compressive state it is also possible to be in extended state.
