Description

technical field [0001] The invention relates to the technical field of air tightness detection, in particular to an intelligent air tightness detection device and a detection method of an electromechanical valve. Background technique [0002] Most of the existing gas meter electromechanical valve air tightness detection methods use a U-shaped tube to detect the leakage value of the electromechanical valve, and the leakage value of the electromechanical valve is judged by the change of the liquid level on both sides of the U-shaped tube within a certain period of time. This method requires manual observation of the liquid position changes on both sides of the U-shaped tube to calculate whether the leakage value meets the requirements. However, the existing electromechanical valve detection methods have the following deficiencies: [0003] (1) The leakage value of the electromechanical valve is manually judged, and the test results are greatly affected by human factors, which...
