[0002] Filling is a key process in the production of carbonated beverages. Common filling methods include the typical double filling method and the single filling method. Sometimes a combined filling method is also used. The filling valve is an on-off valve that accurately and quantitatively controls the flow rate.

[0003] An existing filling valve (Announcement No.: CN217297276U) has at least the following disadvantages:

[0004] When the above patent is in use, carbonated beverages are filled into the beverage bottle through the filling valve, and the filling valve is manually controlled to open and close. Since workers will become tired after working for a long time, they may accidentally touch the switch handle of the filling valve, causing the beverage to leak out and pollute the working environment, affecting the subsequent beverage filling work. Utility Model Content

[0024] After the liquid outlet end of the tapered liquid outlet tube 4 is inserted into the interior of the beverage bottle mouth 2, the tapered liquid outlet tube 4 is manually pressed to slide upward along the inner wall of the filling valve body 1. When the chamfer at the top of the tapered liquid outlet tube 4 abuts against the outer surface of the clamping block 20 close to the inner wall of the filling valve body 1, the upward movement of the tapered liquid outlet tube 4 drives the clamping block 20 to move away from the fixing ring 18. At this time, the arc protrusion is separated from the arc clamping groove, and the sealing plate 17 is released from the limit. When the filling valve body 1 is not in use, the position of the sealing plate 17 can be limited by the device to prevent the staff from accidentally touching the switch handle of the filling valve, causing the beverage to leak and pollute the working environment, thereby ensuring that the subsequent beverage filling work can proceed normally.

[0025] In this embodiment, a conical liquid outlet pipe 4 is slidably installed on the inner wall near the bottom end of the filling valve body 1, a retaining ring is fixedly installed on the top of the conical liquid outlet pipe 4, a retaining ring is fixedly installed on the inner wall of the bottom end of the filling valve body 1, and a rubber sealing ring 16 is fixedly installed on the outer surface of the conical liquid outlet pipe 4 near the retaining ring. The rubber sealing ring 16 is used to seal the conical liquid outlet pipe 4 and the inner wall of the filling valve body 1, and a limiting ring 5 is fixedly installed on the outer surface of the conical liquid outlet pipe 4 near the bottom end. A spring 6 is sleeved on the outer surface of the conical liquid outlet pipe 4, and the spring 6 is arranged between the limiting ring 5 and the retaining ring. The spring 6 is used to make the conical liquid outlet pipe 4 leave the beverage bottle mouth 2, and the conical liquid outlet pipe 4 can be reset downward, which is convenient for the reset movement of the arc protrusion and the arc groove.

[0026] In this embodiment, a sealing nut 7 is fixedly installed on the top of the filling valve body 1, a sliding column 10 is fixedly installed on the upper surface of the middle position of the sealing plate 17, the top of the sliding column 10 passes through the upper surface of the sealing nut 7 and is fixedly installed with a baffle 8, the outer surface of the sliding column 10 is sleeved with a tension spring 9, the top of the tension spring 9 is fixedly installed with the lower surface of the baffle 8, the bottom end of the tension spring 9 is fixedly installed with the lower surface of the sealing nut 7, a supporting block 11 is fixedly installed on the circumferential outer surface of the filling valve body 1, an L-shaped handle 12 is rotatably installed between the inner walls of the top of the supporting block 11, a mounting seat 13 is fixedly installed on the upper surface of the baffle 8, a driving column 15 is fixedly installed between the inner walls of the mounting seat 13, a driving groove 14 is penetrated through the outer surface of the L-shaped handle 12 close to the driving column 15, and the driving column 15 is slidably installed with the inner wall of the driving groove 14.

[0027] When filling carbonated beverages, the L-shaped handle 12 is manually squeezed to rotate around the rotating mounting fulcrum of the support block 11. The L-shaped handle 12 drives the baffle 8 to move upward through the cooperation of the driving groove 14 and the driving column 15, and the baffle 8 drives the sliding column 10 to move upward, so that the sliding column 10 drives the sealing plate 17 to move upward. At this time, the sealing plate 17 leaves the sealing protrusion, and the carbonated beverage can flow into the interior of the beverage bottle through the filling valve body 1. The present device facilitates the filling of carbonated beverages.

[0028] In this embodiment, a liquid inlet pipe joint 3 is fixedly installed on the circumferential outer surface of the filling valve body 1. The liquid inlet pipe joint 3 is arranged above the sealing plate 17. The liquid inlet pipe joint 3 is connected to the interior of the filling valve body 1. Before use, the filling valve body 1 is connected to the carbonated beverage storage tank body through a hose and the liquid inlet pipe joint 3.

[0029] In the present embodiment, it should be noted that since carbonated beverages contain acidic carbonic acid, they are easy to corrode the filling valve body 1 made of ordinary metal. In the present document, the filling valve body 1 is made of stainless steel, which can prevent the corrosion of carbonic acid and increase the service life of the filling valve body 1.

[0030] It should be noted that, before use, the filling valve body 1 is connected to the carbonated beverage storage tank body through a hose and a liquid inlet pipe joint 3. When in use, the operator aligns the tapered liquid outlet pipe 4 with the beverage bottle mouth 2, and then inserts the liquid outlet end of the tapered liquid outlet pipe 4 into the interior of the beverage bottle mouth 2. The tapered setting of the liquid outlet end of the tapered liquid outlet pipe 4 can be used for beverage bottle mouths 2 of different calibers, thereby increasing the applicability of the device. After the liquid outlet end of the tapered liquid outlet pipe 4 is inserted into the interior of the beverage bottle mouth 2, the tapered liquid outlet pipe 4 is manually pressed to slide upward along the inner wall of the filling valve body 1. When the chamfer at the top of the tapered liquid outlet pipe 4 abuts against the outer surface of the block 20 close to the inner wall of the filling valve body 1, the block 20 is driven to move away from the fixing ring 18 by the upward movement of the tapered liquid outlet pipe 4. At this time, the arc The convex block is separated from the arc groove, and the sealing plate 17 is released from the limit. Through this device, when the filling valve body 1 is not in use, the position of the sealing plate 17 can be limited to prevent the staff from accidentally touching the switch handle of the filling valve, causing the beverage to leak and pollute the working environment, thereby ensuring that the subsequent beverage filling work can be carried out normally; when filling carbonated beverages, the L-shaped handle 12 is manually pinched to rotate around the rotating mounting fulcrum of the support block 11. The L-shaped handle 12 drives the baffle 8 to move upward through the cooperation of the driving groove 14 and the driving column 15, and drives the sliding column 10 to move upward through the baffle 8, so that the sliding column 10 drives the sealing plate 17 to move upward. At this time, the sealing plate 17 leaves the sealing protrusion, and the carbonated beverage can flow into the interior of the beverage bottle through the filling valve body 1. The present device is convenient for filling carbonated beverages.
