Through the cooperation of manual valves, regulating valves, water pumps and flow meters, while improving the header cleaning quality, the flow of the header body can be tested and calibrated to ensure the uniformity of water spraying from the nozzles of the header body and uniform cooling of the strip, thereby improving the cooling performance of the strip and reducing the wave shape of laminar cooling of the strip, thereby solving the problem of manually cleaning blocked nozzles, realizing the recycling of the header body, reducing spare parts costs and manpower investment, and bringing convenience to subsequent equipment maintenance;

[0019] The present invention also provides a method for using the manifold cleaning and calibration device, and the specific steps are as follows:

[0020] S1: When cleaning the manifold body: first fill the water tank with diluted high-efficiency cleaning agent, set the regulating valve to 100% opening through the first and second level control system, then start the water pump, open all valves on the U-shaped pipe, tee pipe and fixed pipe, and circulate the cleaning agent to clean the manifold body until the water flowing from the nozzle of the manifold body is free of impurities and the inner wall is free of adhesions.

[0021] S2: When calibrating the flow rate of the manifold body: first open the manual valve of the water inlet pipe to fill the clean water tank with water, set a certain proportional opening degree of the regulating valve through the first and second level control systems, and then start the water pump through the operation control cabinet and open all valves on the pipeline.
