The invention relates to a valve inner leakage detection method and device, a storage medium and electronic equipment. The method comprises the steps that a temperature value corresponding to a valve outlet is obtained; under the condition that the temperature value is smaller than a preset temperature threshold value, a corresponding acoustic emission signal at the outlet of the valve is obtained; and according to the acoustic emission signal and a valve inner leakage identification model, determining whether the valve has inner leakage or not. Therefore, the leakage condition of the valve can be accurately and effectively detected, and the safety monitoring of the valve and the pipeline is ensured. 本公开涉及一种阀门内漏检测方法、装置、存储介质及电子设备，所述方法包括：获取阀门出口处对应的温度值；在所述温度值小于预设的温度阈值的情况下，获取所述阀门出口处对应的声发射信号；根据所述声发射信号和阀门内漏识别模型，确定所述阀门是否发生内漏。由此，可对阀门的泄漏情况进行准确有效检测，保证阀门和管道的安全监控。
