A: The valves at the discharge port of the milk tank play multiple roles. The valves numbered 1 - 4 (black spherical handle valves) are used to control the on-off of fluids (milk or cleaning fluid, etc.). By opening and closing different valves, it can switch between milk transportation and cleaning solution transportation modes. The "milk discharge" valve is specially used to control the outflow of milk from the tank, ensuring smooth discharge of milk and good sealing to prevent milk leakage and the entry of external impurities.

A: Under the premise of meeting food hygiene and safety standards and cleaning the tank thoroughly, it can be used to transport some other liquid foods with similar properties (such as liquid dairy products, juice in some cases). However, it is not suitable for transporting chemicals, corrosive liquids, etc., because it may damage the tank and cause cross - contamination, which will affect the subsequent use of transporting milk.

A: Regularly clean the surface of the valve to remove milk residues and dust. Check the flexibility of the valve handle, and add lubricating oil appropriately (food - grade lubricating oil) if there is stuck. Regularly check the sealing performance of the valve, and replace the sealing ring in time if there is leakage. For long - term unused valves, conduct regular opening and closing tests to prevent valve core sticking.

A: It is recommended to carry out a comprehensive maintenance of the milk tank every 3 - 6 months, depending on the frequency of use. Comprehensive maintenance includes internal and external cleaning of the tank, inspection of all valves, pipelines, temperature control systems (if any), thermal insulation layers, etc. For milk tanks used in harsh environments or high - frequency transportation, the maintenance cycle should be appropriately shortened.
