Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a filling valve suitable for different bottle types. Background Technology

[0002] Filling valves are precision devices that control the filling of liquids or gases, possessing functions of metering, sealing, and leak prevention. In carbonated beverage filling, valves must employ isobaric filling technology, first injecting carbon dioxide into the container to balance the pressure and prevent foam overflow. Simultaneously, low-temperature and high-speed filling are used to ensure the stable dissolution of carbon dioxide gas, thereby guaranteeing the quality of subsequent fillings.

[0003] When filling different bottles, the existing filling valves require the centering cup to be adjusted according to the size, shape and capacity of the bottle to ensure the accuracy and efficiency of the filling process. However, the existing centering cup requires the operator to manually loosen the fixing screw, replace the appropriate centering cup, and then tighten it again. This process is not only time-consuming, but also prone to inaccurate adjustment due to human error. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-2 The filling valve shown is suitable for different bottle types and includes a valve body 1, an inflation tube 3, a guide sleeve 4, an exhaust valve 5, and a docking mechanism 6. An inflation valve 2 is slidably mounted on the top of the valve body 1. The inflation tube 3 is fixedly connected to the bottom of the inflation valve 2. The guide sleeve 4 is fixedly connected to the inside of the valve body 1. The inflation valve 2 and the guide sleeve 4 are slidably interlocked. The exhaust valve 5 is fixedly connected to the bottom of the valve body 1. A first compression spring 7 is sleeved on the outside of the inflation valve 2. One end of the first compression spring 7 is fixedly connected to the inner wall of the valve body 1, and the other end of the first compression spring 7 is fixedly connected to the inflation valve 2. The inflation valve 2 can inject carbon dioxide into the container through the inflation tube 3 and discharge the air in the bottle through the exhaust valve 5 to balance the pressure, thus enabling the filling of carbonated water. At the same time as filling, carbon dioxide is refluxed through the inflation tube 3 until filling is complete. The docking mechanism 6 is located at the bottom of the exhaust valve 5 and is used to hold different bottle types together.

[0030] Specifically, the docking mechanism 6 includes a centering cup 61, a diverting umbrella 62, and a snap-fit ​​mechanism 63. The centering cup 61 is sleeved on the outside of the exhaust valve 5. The inner cavity of the centering cup 61 is conical and contracts towards the exhaust valve 5. The contraction structure can adapt to bottle mouths of different diameters. By fine adjustment, it can match various bottle types, enhancing the versatility of the equipment. It can also guide the gas and liquid to flow more smoothly, reducing turbulence and eddies, and ensuring the stability of exhaust and liquid injection during the filling process. The diverting umbrella 62 is fixedly sleeved on the outside of the inflation tube 3. The diverting umbrella 62 allows the soda and water to be evenly distributed during filling, avoiding direct impact of liquid on the bottle bottom or bottle wall, thereby reducing foam generation and liquid splashing. The snap-fit ​​mechanism 63 is located inside the exhaust valve 5 and is used for multi-point positioning of the centering cup 61, facilitating quick replacement of the centering cup 61, further expanding the application range of the entire filling device and making it easier to use.

[0031] Furthermore, the locking mechanism 63 includes a locking rod 631, a pull rod 632, and a second compression spring 633. The exhaust valve 5 has equidistant locking grooves inside, and the centering cup 61 has equidistant locking holes on its inner wall. One end of the locking rod 631 is slidably inserted into the inner cavity of the locking groove, and the other end is slidably inserted into the inner cavity of the locking hole. The outer wall of the exhaust valve 5 has equidistant pull grooves communicating with the locking grooves. The pull rod 632 passes through the pull grooves and is fixedly connected to the locking rod 631. The second compression spring 633 is located inside the locking groove. One end of the second compression spring 633 is fixedly connected to the locking rod 631, and the other end is fixedly connected to the inner wall of the locking groove. The second compression spring 633 always provides a stable elastic force to the locking rod 631, thereby ensuring stable locking between the locking rod 631 and the locking hole. This allows centering cups 61 of different specifications to be firmly locked onto the outside of the exhaust valve 5, making it suitable for more bottle types.

[0032] Furthermore, a bottle mouth sealing gasket 8 is fitted on the outside of the exhaust valve 5. The bottle mouth sealing gasket 8 is located inside the centering cup 61. The bottle mouth sealing gasket 8 can ensure that the inner cavity of the exhaust valve 5 is completely sealed when not exhausting, preventing gas or liquid backflow. The bottle mouth sealing gasket 8 is made of rubber, which can absorb minor vibrations or impacts between the bottle mouth and the centering cup 61, reducing mechanical wear.

[0033] Furthermore, a sealing ring 9 is fixedly connected to the bottom end of the inflation valve 2 to seal the inner cavity of the exhaust valve 5. During inflation or deflation, the sealing ring 9 can maintain the pressure balance of the inner cavity under the elastic force of the first compression spring 7, avoiding uneven filling or liquid splashing caused by pressure fluctuations. At the same time, by precisely controlling the opening and closing of the exhaust valve 5, the sealing ring 9 ensures the coordination of gas discharge and liquid injection during the filling process, reduces errors, and facilitates use.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
