Background technique [0002] The uneven flow rate of the internal flow field of the check valve used in the range hood will lead to a decrease in the working efficiency of the hood, vibration of the check valve and even noise. At present, there is a lack of test devices and test methods for the inner surface pressure of the hood check valve in the industry, resulting in the lack of experimental verification of the research method on the inner surface of the hood check valve in the industry, and the obtained research law cannot be verified by experiments. The accuracy of the numerical simulation of the pressure on the inner wall of the check valve of the hood cannot be measured, so it is difficult to evaluate the distribution o...
