The working principle of the direct pressure (pressure drop) air tightness detector
The principle is to fill the product with a certain pressure of gas, and the flow rate is the highest when inflating. If the product is qualified and there is no leakage, the product will not be filled after the product is full, and the flow rate will drop to zero; otherwise, the product is unqualified and leaking, and the pressure will drop. , the instrument continues to replenish the gas leaked from the product, and the gas flow will be detected in the instrument.
