DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0022] See also Figure 1~Figure 5 In an embodiment of the utility model, a filling valve comprises: a bracket, a telescopic member and a replacement cylinder, which realizes the detachable replacement of the replacement cylinder, and utilizes the non-stickiness and self-lubricating properties of polytetrafluoroethylene material to avoid the adhesion of food raw materials and reduce the difficulty of cleaning the equipment, as follows: a filling cylinder 14 is installed on the bracket, a feeding pipe 15 is arranged on the filling cylinder 14, and a guide cavity 11 is formed in the filling cylinder 14, the bracket comprises a mounting plate 4 connected to the filling cylinder 14, a connecting rod 3 is arranged on the mounting plate 4, and a positioning plate 2 is arranged at one end of the connecting rod 3 away from the mounting plate 4; a driving device 1 is fixedly installed on the positioning plate 2, an actuating rod 5 is connected to the driving device 1, and a connecting member 6 is arranged at one end of the actuating rod 5 away from the driving device 1, a positioning block 7 is connected to the connecting member 6, and the positioning block 7 is connected to the telescopic member.
[0023] When in use, by controlling the action of the driving device 1, the telescopic part can be moved upward. At this time, the guide cavity 11 and the feed pipe 15 are in a conducting state. In this state, the external pumping device can pump the food raw materials into the feed pipe 15 and enter the filling bottle body through the guide cavity 11.
[0024] The telescopic member is slidably fitted with the filling cylinder 14, and a connecting seat 17 is detachably installed at the bottom of the filling cylinder 14. The interior of the telescopic member is a hollow structure, and an annular groove 16 for placing a sealing ring is formed on the telescopic member. When the sealing ring is placed between the telescopic member and the filling cylinder 14, it can prevent food raw materials from entering the upper part of the filling cylinder 14 through the gap between the telescopic member and the filling cylinder 14 during the filling process, causing pressure relief. On the one hand, pressure relief can be avoided during the filling process, and on the other hand, food raw materials can be prevented from entering the upper part of the filling cylinder 14, causing difficulty in cleaning. The telescopic member includes a filling piston cylinder 8 detachably connected to the positioning block 7, and the end of the filling piston cylinder 8 away from the positioning block 7 is clamped with a piston cylinder end 13. Exemplarily, the above-mentioned detachable connection method includes a clamping or a threaded connection, thereby facilitating the connection and disassembly of the positioning block 7 and the filling piston cylinder 8.
[0025] During the filling operation, the guide cavity 11 and the feed pipe 15 are in a conducting state, and the external pumping device can pump the food raw materials into the feed pipe 15 and enter the filling bottle body through the guide cavity 11. At the same time, the existence of the sealing ring can prevent the food raw materials from entering the upper part of the filling cylinder 14. When the filling is completed and the filling cylinder 14 and the telescopic part need to be cleaned, the connecting seat 17 is first removed, and then the telescopic part can be moved toward the bottom of the filling cylinder 14 by controlling the action of the driving device 1. At this time, the sealing ring can be used to scrape off the food raw materials adhered to the inner wall of the filling cylinder 14 at the bottom of the sealing ring, thereby reducing the difficulty of cleaning.
[0026] In this embodiment, since the filling piston cylinder 8 and the piston cylinder end 13 are in a clamping state, that is, the two can be detachably connected, when the replacement cylinder needs to be replaced, the filling piston cylinder 8 can be separated from the piston cylinder end 13, thereby facilitating the removal of the old replacement cylinder and the installation of a new replacement cylinder.
[0027] The replacement cylinder is arranged inside the telescopic part, and the replacement cylinder is made of polytetrafluoroethylene material. It should be supplemented that polytetrafluoroethylene material is a high-performance synthetic polymer material, which is generated by polymerization reaction of tetrafluoroethylene monomer, has non-stickiness and self-lubricating properties, and is applied to the present device to effectively prevent food raw materials from entering the replacement cylinder under the action of pressure, and adhering to the inner wall of the replacement cylinder due to temperature rise or fall, thereby preventing blockage in the replacement cylinder and ensuring that the inert gas can enter the filling bottle through the replacement cylinder.
[0028] The replacement cylinder includes a first inner liner 10 sleeved in the filling piston cylinder 8 and a second inner liner 12 sleeved in the piston cylinder end 13. When the filling piston cylinder 8 and the piston cylinder end 13 are snap-fitted to form the telescopic member, the first inner liner 10 and the second inner liner 12 are sealed and fitted at the ends.
[0029] During assembly, first separate the filling piston cylinder 8 from the piston cylinder end 13, then insert the first inner liner 10 into the filling piston cylinder 8, insert the second inner liner 12 into the piston cylinder end 13, and finally snap-fit the filling piston cylinder 8 and the piston cylinder end 13. After the filling piston cylinder 8 and the piston cylinder end 13 are snap-fitted, the first inner liner 10 and the second inner liner 12 end portions are sealed and fit together, thereby preventing food materials from passing through the first inner liner 10 and the second inner liner 12 ends and entering the inner walls of the filling piston cylinder 8 and the piston cylinder end 13.
[0030] Through the above arrangement, the first inner liner 10 and the second inner liner 12 can be detachably replaced, and the non-stickiness and self-lubricating properties of the polytetrafluoroethylene material are utilized to avoid the adhesion of food raw materials and reduce the difficulty of cleaning the equipment.
[0031] The first liner cylinder 10 and the filling piston cylinder 8 are both provided with an air inlet 9 , and the inert gas can enter into the interior of the telescopic member through the air inlet 9 .
[0032] During use, inert gas is first delivered into the filling bottle through the air inlet 9. When the inert gas enters the filling bottle, the air in the filling bottle can be discharged, thereby preventing bacteria in the air from multiplying on the food raw materials and causing food spoilage. After the air in the filling bottle is discharged, the food raw materials enter the filling bottle through the feed pipe 15 and the guide cavity 11. After the filling is completed, the inert gas will enter the filling bottle through the first inner liner 10 and the second inner liner 12. On the one hand, it can fill the remaining space inside the filling bottle and increase the storage time of the food. On the other hand, it can squeeze out the video raw materials entering the first inner liner 10 and the second inner liner 12 to prevent the internal space of the first inner liner 10 and the second inner liner 12 from being blocked.
