As shown in figure 1, filling operation principle process is as follows：
Bottle, which rises, opens filling valve jack-up, due to it is filling when material cylinder M inside for whirlpool blower fan extract negative pressure mechanism, bottle
Oral area is sealed, now identical with negative pressure value in filling bucket in bottle, below standard atmospheric pressure, and the valve stem cylinder 10 at top leads to
Gas, which lifts valve rod 4, allows its lower valve core pipe 1 and upper valve core pipe 3 to form path.
Now liquid is flowed into bottle, and gas is withdrawn into material cylinder M by lower valve core pipe 1 and upper valve core pipe 3 and pushed up in bottle
Portion, liquid start under gravity it is filling, when first return-air hole 14 of the filling liquid to the bottom of lower valve core pipe 1, liquid will
First return-air hole 14 of the bottom of lower valve core pipe 1 is sealed, and the second return-air hole of middle part of lower valve core pipe 1 can be only changed into by taking out negative-pressure air-flow
15 extract negative pressure, and flow rate of liquid, which can be changed into, continues at a slow speed filling, when filling liquid to 1 middle part of lower valve core pipe second time
During stomata 15, filling valve is extracted negative pressure passage and all blocked by the second return-air hole 15, but the air on liquid level top also has in bottle
Some negative pressure, liquid level can be filling more than stopping after the second return-air hole of middle part 15 of lower valve core pipe 1 continuation rising 3-5mm.
Because liquid first contacts the first return-air hole of bottom 14 of blocking lower valve core pipe 1 in pouring process, then contact in the middle of blocking
The second return-air hole of position 15, negative-pressure air-flow sectional area from large to small, by negative pressure value changes twice from large to small, completes charging
It is filling.
Bottle after filled declines a segment distance in the presence of equipment guide rail and closes valve, have turned off filling valve center
Sealing ring, due to that can pass through in material cylinder for negative pressure state in the liquid in the presence of its negative pressure in bottle in the middle of lower valve core pipe 1
Unnecessary liquid and foam are withdrawn into material cylinder M by second return-air hole 15 at position by upper valve core pipe 3, and realization is once evacuated,
As bottle continues to decline in the presence of equipment guide rail, bottleneck departs from filling valve to be sealed, the reduction of bottle liquid level upper space
Communicate, because the negative pressuren zone of lower valve core pipe 1 and material cylinder M upper ends keeps UNICOM to be in still negative pressure evacuated, pass through with ambient atmosphere
The first return-air hole of bottom 14 of lower valve core pipe 1 extracts the small amount of liquids and foam on filling liquid level top again, realizes secondary evacuation,
It is precisely consistent to the liquid level in filling bottle so as to really realize by evacuation process twice, when bottle continues in the presence of guide rail
Valve stem cylinder 10 at the top of while decline, which is acted on, the closing for realizing return gas channel is pushed away under valve rod 4, so as to realize no bottle and bottle
Son drops to will not be pumped into extraneous air in material cylinder M when extreme lower position enters bottle outlet, it is to avoid outside air pollution liquid
It is dangerous.
Valve stem cylinder 10 is with the second O-ring seal 9, support set 8, positioning valve pocket 7, y-type seal ring 6, bushing 5, valve rod
4 composition top return-air switching devices 13, achieve the effect to upper valve core pipe 2 and the circulation of the break-make gas of lower valve core pipe 1, from
And realize and decline without bottle and bottle into during bottle outlet and will not will increase the danger of pollution liquid in extraneous air suction material cylinder.
