In jacking sleeve 6, form second and close up 19, be inserted with the lifting plunger 20 that cooperates with handwheel rotating shaft 3 simultaneously, be formed with the gap between jacking sleeve 6 and the lifting plunger 20, on the lifting plunger 20 second close up 19 below be provided with can with second second seal ring 21 that closes up 19 fitted seal, below second seal ring 21, be provided with slip guiding sleeve 22, slip guiding sleeve 22 structures as shown in figure 11, this slip guiding sleeve 22 is fixedlyed connected with jacking sleeve 6 inwalls by screw thread, the bottom of slip guiding sleeve 22 is a cecum, be placed with second Returnning spring 23 in the cover, the bottom of lifting plunger 20 is injected in the slip guiding sleeve 22 and is pushed down second Returnning spring 23, be processed with the second channel 24 of up/down perforation on the sidewall of slip guiding sleeve 22, the below, bottom surface of slip guiding sleeve 22 is provided with the 3rd seal ring 25, form second radial passage 26 between the bottom surface of slip guiding sleeve 22 and the 3rd seal ring 25, the bottom of jacking sleeve 6 is formed with the 3rd and closes up 27, above the 3rd closing in 27, be placed with tubbiness cylinder 28, tubbiness cylinder 28 structures as shown in figure 12, the diameter of this tubbiness cylinder 28 is bigger than the 3rd closing in 27, tubbiness cylinder 28 openings upwards, and its sidewall forms four-way 32, its inside is placed with spheroid 29, on the wall body of tubbiness cylinder 28, the top of spheroid 29 is provided with first radial passage 30, by the gap between jacking sleeve 6 and the lifting plunger 20, second channel 24 on the slip guiding sleeve 22, second radial passage 26, the hollow portion of the 3rd seal ring 25, first radial passage 30 on the tubbiness cylinder 28, the gap of the four-way 32 on the tubbiness cylinder 28, the 3rd closing in 27 common air flues 31 of giving vent to anger that form.
The effect of first seal ring 9 is: during normality, the effect that jacking sleeve 6 is subjected to first Returnning spring 13 is lifted, first seal ring 9 and first closing in 5 cooperate 15 blocking-up of an inflation air flue, when jacking sleeve 6 is inflated rifle 33 and presses down, first seal ring 9 and first closing in 5 break away from, 15 conductings of inflation air flue that is to say that first seal ring 9 is that blocking-up and the conducting of controlling inflation air flue 15 used.
The effect of second seal ring 21 is: during normality, under the effect of second Returnning spring 23, second seal ring 21 and second closing in 19 cooperate air flue 31 blocking-up of giving vent to anger, when lifting plunger 20 is subjected to handwheel rotating shaft 3 and presses down, second seal ring 21 and second closing in 19 separate, air flue 31 conductings of giving vent to anger, the give vent to anger blocking-up and the conducting of air flue 31 used so second seal ring 21 is control.
During inflation as shown in Figure 5, inject special-purpose charge gun 33, charge gun 33 is big the support of hook switch opening, at this moment grab 18 breaks away from clasp 16, jacking sleeve 6 breaks away from the lock effect of colluding of hook switch 17, the same time is under the transmission of slide guide chamfering 7, charge gun 33 presses down jacking sleeve 6, the effect that lifting plunger 20 is subjected to second closing in 19 is also pressed down synchronously, at this moment the air flue 31 of giving vent to anger is blocked by second cooperation of closing up 19 and second seal ring 21, and inflation air flue 15 descends owing to first seal ring 9 and first closing in 5 separates and conducting, realize inflation, after finishing inflation, directly extract charge gun 33, under the effect of first Returnning spring 13, jacking sleeve 6 rises at once, first seal ring 9 and first closing in 5 are cooperated again, 15 blocking-up of inflation air flue, jacking sleeve 6 rises to grab 18 and colludes lock again with clasp 16, and when jacking sleeve 6 rose, second seal ring 21 on the lifting plunger 20 all cooperated with second closing in 19 under the effect of second Returnning spring 23 all the time, so whole gas replenishment process, the air flue 31 of giving vent to anger is obstructed.
During with gas as shown in Figure 6, turn handwheel 2, handwheel rotating shaft 3 descends through hook switch 17 middle parts, lifting plunger 20 is pressed down, second seal ring 21 and second closing in 19 separate, the air pressure of steel cylinder inside is tubbiness cylinder 28 jack-up, at this moment, air flue 31 conductings of giving vent to anger, give vent to anger air flue 31 successively the second radial passage 26-second channel 24-second on the hollow portion-slip guiding sleeve 22 of the first radial passage 30-the 3rd seal ring 25 on the gap-tubbiness cylinder 28 between the 3rd closing in 27-jacking sleeve 6 and the tubbiness cylinder 28 close up 19, flow out to blowing mouth 4, when closing, reverse turn handwheel 2, handwheel rotating shaft 3 withdrawals, lifting plunger 20 rises, second seal ring 21 and second closing in, 19 fitted seal, the air flue 31 of giving vent to anger is blocked, and the air pressure in the air flue 31 of at this moment giving vent to anger is identical with the steel cylinder air pressure inside, and tubbiness cylinder 28 drops to the 3rd closing in 27 places.
If when the lawless person wanted to steal gas, first turn handwheel 2 was air flue 31 conductings of giving vent to anger, be inverted whole steel cylinder then, this moment the control valve structure as shown in Figure 7, at this moment, spheroid 29 can move to the 3rd seal ring 25 places, and air flue 31 blocking-up of giving vent to anger, this just can realize preventing illegal gas steathily.
This control valve can also extract raffinate, and step is: inject device for sucking liquid 34, make control valve be in inflated condition, promptly inflate air flue 15 conductings, be inverted steel cylinder then, like this, raffinate in the steel cylinder just can flow out along inflation air flue 15, and the control valve structure of this moment as shown in Figure 8.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
