[0018] The same valve body mechanism 26 is installed on the left side of the air return base 15 and the liquid return base 21; the valve body mechanism 26 includes an end cover 13, a spring seat 14, a diaphragm 16, a compression spring 17, a valve stem 18, and a corrugated sealing sleeve 19. The end cover 13 is installed on the left end surface of the spring seat 14; a compression spring 17 is installed inside the spring seat 14; and the valve stem 18 is inserted into the compression spring 17.
[0019] The valve stem 18 passes through the spring seat 14 from left to right in sequence; a corrugated sealing sleeve 19 is sleeved on the right end of the valve stem 18; a diaphragm 16 is installed at the intersection of the end cover 13 and the spring seat 14; a second diaphragm valve 12 is installed on the side of the diaphragm 16 inside the valve body mechanism 26 of the return air base 15; and a first diaphragm valve 11 is installed on the side of the diaphragm 16 inside the valve body mechanism 26 of the return liquid base 21.
[0020] The exhaust seat 1 of the device is fixed on the upper end of the reflux seat 2, and their internal gaps are connected. The liquid inlet seat 3 is fixed on the side of the reflux seat 2. The liquid flows into the cavity of the reflux seat 2 through the liquid inlet seat 3. The return air pipe 10 is fixed on the upper valve seat 4 through a nut. The upper end of the return air pipe 10 passes through the interior of the reflux seat 2. The internal gap of the return air pipe 10 and the internal gap of the reflux seat 2 form a liquid return channel, and the internal gap of the return air pipe 10 and the internal gap of the exhaust seat 1 form an exhaust channel. The internal gap of the valve cavity of the upper valve body 5 and the lower valve body 7 forms a liquid inlet channel, the sealing ring 6 is fixed on the return air pipe 10, the upper end of the return air needle 9 is fixed on the lower end of the return air pipe 10, and the bottle mouth pad 8 is fixed on the lower end face of the lower valve body 7.
[0021] During filling, under the action of the lifting cam, the bottle rises and the bottle mouth presses against the bottle mouth pad 8, and the upper valve body 5 leaves the sealing ring 6. At this time, the valve is opened and the liquid is injected into the bottle. The air in the bottle enters the exhaust seat 1 through the internal gaps of the return needle 9 and the return pipe 10 in turn. At this time, the first diaphragm valve 11 is opened, the second diaphragm valve 12 is closed, the exhaust channel is unobstructed, and the gas enters the first diaphragm valve 11 from the exhaust inlet, and then is discharged into the liquid cylinder from the exhaust outlet of the exhaust seat 1. At this time, the pressure in the liquid cylinder increases, and the liquid can flow into the bottle faster.
[0022] After filling, the bottle drops under the action of the cam, and the bottle mouth leaves the bottle mouth pad 8. Under the action of the spring force, the upper valve body 5 moves upward, and the sealing ring 6 contacts the upper valve body 5. At this time, the valve is closed, the first diaphragm valve 11 is closed, and the second diaphragm valve 12 is opened. The remaining liquid in the bottle enters the reflux seat 2 through the internal gaps of the return needle 9 and the return pipe 10 in turn. At this time, the return liquid channel is unobstructed, and the excess liquid enters the second diaphragm valve 12 of the diaphragm valve from the entrance of the return liquid channel, and then flows into the internal gap of the reflux seat 2, and flows into the external return air pipeline from the outlet of the reflux channel until the liquid level in the bottle drops to the same level as the lower plane of the return needle. The diaphragm valve is controlled by the solenoid valve, with a fast response speed and higher accuracy in correcting the liquid level.
[0023] The diaphragm 16 is installed between the end cover 13 and the spring seat 14. The valve stem 18 compresses the compression spring 17 in the spring seat 14. The lower end of the valve stem is installed with a bellows seal sleeve 19, and the bottom is installed with a base 15. When gas enters the diaphragm valve, the diaphragm 16 presses the valve stem 18 downward, the bellows seal sleeve 19 is stretched, and the bottom blocks the entrance. At this time, the internal channel of the diaphragm valve is blocked. When there is no ventilation, under the elastic force of the compression spring 17, the valve stem 18 moves upward, and the bellows seal sleeve 19 retracts. At this time, the internal channel of the diaphragm valve is unblocked.
