[0002] The filling valve is a control element commonly found in liquid filling equipment. Its main function is to adjust the flow and pressure of the liquid to ensure that the liquid can enter the container accurately and stably. It is widely used in mechanical equipment such as food, packaging, petrochemical, metallurgy, painting, vehicles, printing and dyeing. The working principle of the filling valve is relatively simple but crucial. It is usually composed of components such as valve body, valve core, spring and sealing ring. The valve body serves as the outer shell to protect the internal structure. The valve core is the core component, which adjusts the flow and pressure of the liquid by moving up and down. The spring supports the valve core to keep it in the right position. The sealing ring ensures the sealing performance of the valve and prevents liquid leakage. When the liquid needs to enter the container, it flows into the valve body of the filling valve through the pipeline. The movement of the valve core determines whether the liquid can pass through the valve.

[0003] However, the injection pipe of the filling valve group is usually in the external environment, and it is easy to be contaminated by bacteria. When it is inserted into the container during injection, it enters the container and causes contamination.
