[0014] Compared with the prior art, the precise dosing system based on valve control provided by this solution uses the liquid storage tank as the liquid medicine storage container of the whole system. The liquid storage tank is responsible for storing the liquid medicine to be filled. Its design is reasonable, which can ensure the stable storage of the liquid medicine and provide a reliable raw material basis for the subsequent dosing operation. The L-shaped frame is fixedly installed on the top of the liquid storage tank. It not only provides structural support for the system but also may serve as an installation platform for other components (such as the lifting mechanism), enhancing the overall stability and functionality of the system. The constant-pressure water pump is set on the liquid storage tank. By providing a stable pressure output, it ensures that the flow rate and speed of the liquid medicine during transportation are stable and controllable, which is crucial for achieving precise dosing and effectively avoiding the problem of inaccurate dosing caused by pressure fluctuations. The liquid guiding pipe, as the channel for liquid medicine transportation, connects the constant-pressure water pump and multiple dosing mechanisms. Its design should consider characteristics such as corrosion resistance, high-pressure resistance, and easy cleaning to ensure the purity of the liquid medicine and the long-term stable operation of the system. Multiple dosing mechanisms are distributed on the liquid guiding pipe, and the precise delivery of the liquid medicine is achieved through valve control. Each dosing mechanism can be operated independently, and the dosing amount can be adjusted according to actual needs, thus meeting the dosing requirements in different scenarios. This design greatly improves the flexibility of the system and the accuracy of dosing. The lifting mechanism is installed on the top of the liquid storage tank and can control the lifting of multiple dosing mechanisms. The lifting mechanism facilitates the maintenance and replacement of the dosing mechanisms and improves the maintainability of the system. The cleaning mechanism is set on the inner wall of the liquid storage tank and is specifically used to clean the residual liquid medicine on the inner wall of the liquid storage tank. This design effectively avoids the corrosion and pollution problems caused by the residual liquid medicine to the liquid storage tank and the system, ensures the cleanliness of the system and its long-term stable operation. The existence of the cleaning mechanism also reduces the difficulty and cost of manual cleaning and improves the automation degree of the system;

[0015] In summary, the precise dosing system based on valve control proposed by the present invention realizes efficient and accurate dosing operations through reasonable structural design and component configuration, and fully considers the maintenance and cleaning issues of the system.
