A bottle mouth sealing gasket 23 is arranged below the valve seat 14, and the end part of the air return pipe 20 extends downwards into the bottle mouth sealing gasket 23.

The working principle is as follows:

(1) the fixed seat 5 and the valve seat 14 are respectively fixed at the top and the bottom of the hydraulic cylinder 18, the valve body 12 is arranged inside the hydraulic cylinder 18, when the bottle body 19 moves below the bottle mouth sealing gasket 23, the bottle body 19 is jacked up and jacked up against the bottle mouth sealing gasket 23 until the top of the bottle mouth sealing gasket 23 butts against the bottom of the valve seat 14, and the air return pipe 20 extends into the bottle body 19 through the bottle mouth of the bottle body 19, as shown in fig. 3-4.

(2) The telescopic end of the driving cylinder 1 is contracted inwards to leave the piston rod 6, the return spring 4 jacks up the spring seat 3 by utilizing the self-rebound force thereof, and further drives the piston rod 6 to move upwards, so as to drive the valve core 13 to move upwards by virtue of the gas injection mechanism and the sleeve 24, so that a gap is formed between the lower end of the valve core 13 and the lower end opening of the valve cavity 141 to start filling, the material in the hydraulic cylinder 18 enters the valve body 12 through the plurality of liquid inlet holes 121 and flows downwards into the valve cavity 141, and further flows towards the lower end of the valve core 13 through the plurality of fences which are arranged on the comb-shaped sleeve 15 and are distributed at equal angles along the circumferential direction, so as to effectively avoid the occurrence of turbulence phenomenon to avoid the generation of filling bubbles, finally, the material is filled into the bottle body 19 through the gap between the lower end of the valve core 13 and the lower end opening of the valve cavity 141, and after the bottle body 19 is filled with the material, the redundant material upwards enters the vent hole 131 through the gas return pipe 20, thereby ejecting the gas injection rod 10 upwards and into the connecting rod holder 7 via the space between the gas injection rod 10 and the sleeve 24 and finally into the cylinder 18 via the gas outlet hole 71, as shown in fig. 5.

(3) When the material in the bottle 19 approaches the end of the muffler 20, the telescopic end of the driving cylinder 1 extends outward to drive the gas injection mechanism to move downward via the piston rod 6, and further drives the valve core 13 to move downward in the same manner, so that the sealing gasket 16 embedded at the lower end of the valve core 13 is sealed and attached to the inner wall of the opening at the lower end of the valve cavity 141 again to cut off the material, as shown in fig. 6.

(4) After filling, one of the diaphragm valves 17 is opened, external carbon dioxide gas enters the diaphragm valve 17 through the gas inlet hole of the diaphragm valve 17, is introduced into the lower end opening of the valve cavity 141 through the gas outlet hole of the diaphragm valve 17 and a corresponding gas passage 142, further enters the top of the bottle body 19 and upwardly enters the vent hole 131 through the gas return pipe 20, so that the gas injection rod 10 is upwardly ejected and enters the connecting rod seat 7 through the space between the gas injection rod 10 and the sleeve 24, and finally is discharged into the liquid cylinder 18 through the gas outlet hole 71, so that the carbon dioxide gas can be recycled, and simultaneously foam and materials in the gas return pipe 20 are ejected back to the liquid cylinder 18, as shown in fig. 7.

(5) The other diaphragm valve 17 is opened to equalize the pressure in the bottle body 19 with the atmospheric pressure, and at this time, the gas in the bottle body 19 enters the other diaphragm valve 17 through the other air passage 142, so that the foam and the material in the bottle body 19 enter the diaphragm valve 17 through the air outlet hole of the other diaphragm valve 17, and are discharged and collected through the air inlet hole of the diaphragm valve 17 to avoid entering the filling environment, and finally the bottle body 19 is driven to descend to leave the mouth seal 23 and remove the bottle body 19, as shown in fig. 8 to 9.

The utility model drives the valve core 13 to act by the actuating mechanism and the air pressure, so as to greatly improve the accuracy of the action, and even if the valve core is used in high-speed filling equipment, the liquid filled into the container can not turn over bubbles, thereby effectively eliminating the liquid level deviation in the container after filling and prolonging the service life; in addition, the carbon dioxide gas for purging is completely recycled by means of the two diaphragm valves 17 for recycling, so that the environmental pollution is avoided, and the resources are effectively saved.
