In use, the present invention is installed in the outside of fluid cylinder, and the outer end of inlet tube 6 is connected with the inside of fluid cylinder
It is logical, material is filled in fluid cylinder；The bottleneck of bottle is inserted upwardly into bottle cover 18, and makes lower end and the shunt umbrella of valve core tube 13
11 are inserted in bottleneck, close the second air flue 154, and piston head 81 moves up under the bounce effect of spring 17, in turn
Valve core tube 13, valve head 14 and gas deflation assembly is driven to move upwardly together, until in the upper end that the upper end of piston 8 resists dsah-pot 7
The upside of wall and sealing ring 16 is fitted in the upper inside walls of open-close valve 5, the first seal bellows 20 and second during this
Seal bellows 25 is compressed；Valve head 14, which moves up, makes the upper end of itself and runner 93 generate gap, at this point, the material in fluid cylinder passes through
Enter the inside of feed liquor cylinder 21 by inlet tube 6, and then flows downwardly through admission chamber 91 and runner 93 and enter in bottle；Open the
One diaphragm valve 1 is so that the control valve chamber 151 in its valve head and control valve block 15 generates gap, and the air in bottle is via spool
The inside of pipe 13 enters in the third counterbore 241 in ventilation end 24, then enters lifting guide sleeve 22 via multiple inclined holes 242
In the first counterbore 221 in, then via multiple open slots 224 enter circular hole 223, finally via return-air chamber 41, first passage 42,
Valve chamber 151, third channel 152 and second channel 153 is controlled to be discharged；After filling material in bottle, the material of spilling can be via
The inside of valve core tube 13 flow up to ventilation end 24 in third counterbore 241 in, and then pass upward through multiple inclined holes 242 into
Enter into the first counterbore 221 in lifting guide sleeve 22, to jacking up sphere 23 to block circular hole 223 upwards, gas is no longer
Be discharged from second channel 153, that is, indicate filling completion, close primary diaphragm valve 1 so that its valve head and control valve chamber 151 again
Sealing.
It being then turned on the second air flue 154 and is passed through compressed air, compressed air enters pressure tank 83 via the first air flue 51,
And then overcome the bounce of spring 17 and push down on piston head 81 and move down, to drive valve core tube 13, valve head 14 and exhaust group
Part moves downwardly together, realizes and seals with the upper end of runner 93 again until valve head 14, so that filling stopping, during this
First seal bellows 20 and the second seal bellows 25 are stretched.
After filling, open the secondary diaphragm valve 2 being set in the second valve chamber 99 and closes another secondary diaphragm valve 2,
Residual gas in bottle enters the second valve chamber 99 via the second communication channel 92, then enters discharge chamber via the 4th communication channel 94
95, exhaust head 27 at this time due to exhaust spring 10 bounce and be pressed in cone shaped countersink 293 so that exhaust valve circle 28
It is sealed against each other with arc taper hole 294, residual gas can only slowly be discharged by pore 271 and enter cavity volume 291, finally
It is discharged to the outside via exhaust duct 292 and tracheae 30.
When needing to clean filling valve, bottle cover 18 is closed, by high-pressure cleaning liquid via tracheae 30 and exhaust duct 292
Into cavity volume 291, under the effect of the pressure, pore 271 is not able to satisfy the passage of big flow, and exhaust head 27 is caused to be pushed up upwards
It rises, so that exhaust valve circle 28 and arc taper hole 294 generate gap, so that cleaning solution can be via 294 He of arc taper hole
Cone shaped countersink 293 enters discharge chamber 95, enters in the second valve chamber 99 via the 4th communication channel 94, then via the second communication channel 92
Into runner 93, then enter via admission chamber 91 inside of feed liquor cylinder 21, then via inlet tube 6 return to fluid cylinder, it thus can be with
The wash cycles of big flow are realized, to reach cleaning requirement.
After the completion of cleaning and before filling the container, need to open two secondary diaphragm valves 2, then by compressed air via purging road
97 and third connecting road 96 be passed into the first valve chamber 98, later, compressed air via the first communication channel 910 enter the second valve chamber
In 99, and then enter discharge chamber 95 via the 4th communication channel 94, so that remaining cleaning solution foam is discharged into appearance via pore 271
Product chamber 291, is finally discharged to the outside via exhaust duct 292 and tracheae 30, influences next exhaust event with foam-resistant stop
Integrality.
Tradition machinery formula filling valve is widely used since at low cost, maintenance is simple by the country, but in high-speed canning, by
Constantly increase in the diameter of sharply increasing for filling head number, fluid cylinder, leads to the material cost of fluid cylinder and the increase width of processing cost
Spend especially prominent, existing filling valve is built in fluid cylinder and is linked to be overall structure with fluid cylinder to realize isobar filling, fluid cylinder
Diameter increase cause the mounting surface of filling valve and fluid cylinder deformation do not reach requirement so that causing gas leakage, leak, and then cause
Fluid cylinder decompression is unable to reach equipressure and influences filling, and the fluid cylinder only processed by high precision apparatus can just meet the requirements,
Therefore difficulty of processing is larger；In addition, existing isobar filling valve can not remove the foam in exhaust passage, thus two can only be used
Carbon oxide gas is purged, at high cost；The present invention separates filling valve and fluid cylinder, and mutual by inlet tube 6 and fluid cylinder
Connection so that the diameter of fluid cylinder is no longer limited by the mounting surface size of filling valve and fluid cylinder, can be greatly reduced fluid cylinder at
Sheet and difficulty of processing；Meanwhile the present invention can thoroughly remove the foam in exhaust passage by compressed air, purging is thorough, comprehensive,
Without carbon dioxide, greatly reduce purging cost, and can also to the channel that all materials in filling valve flow through all into
The perfect cleaning of row；In addition, the present invention blocks the standard that circular hole 223 is filling end with sphere 23, come without flowmeter
It calculates flow and then judges whether to terminate filling, reduce manufacturing cost and operation difficulty.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of skill in the art that it still can be right
Technical solution documented by foregoing embodiments is modified, or is replaced on an equal basis to part of technical characteristic；And this
It modifies or replaces, the spirit and model of technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution
It encloses.
