[0002] A valve is a device used to control fluid flow. It plays a vital role in the pipeline system. It can open and close water flow or other fluids, adjust flow, prevent backflow or leakage, and ensure safe and stable system operation. In the valve production process, sealing test is an indispensable step. First, close the valve to ensure that it is completely closed. Use a water pump or air pump to introduce the corresponding medium into the valve, gradually increase the pressure and observe the pressure gauge reading on the valve. A steady increase in the pressure gauge indicates that the valve has good sealing. If the indication drops or leaks, there is a sealing problem.
