The basic detection principle of the tree body air tightness testing equipment is the pressure peak method (pressure drop method), also known as the pressure reduction method, is to pressurize the internal inflation of the broad body product, and determine whether the product is leaking by real-time detection of the change of the main amount of gas filled in the valve body. The working principle of the specific broad body air tightness testing equipment is to pass the constant pressure intake and balance. Detection of this main process, the sensor and system in the valve body tightness test equipment through a series of sampling, calculation and analysis, to obtain its leakage value, and according to these data and the set allowable leakage to determine OK or NG.
