在管道生产完成后需要进行气密性的检测，如果没有进行检测的塑料管直接投入使用后可能管道中有裂纹会出现漏水的情况，现有的检测方式通常采用人工检测的方法，将塑料管封闭后完全浸入水中，观察是否产生气泡，若未产生气泡则气密性良好，若产生气泡则需进行进一步的检查。After the pipeline is produced, it is necessary to conduct an air tightness test. If the plastic pipe that has not been tested is put into use directly, there may be cracks in the pipe and water leakage may occur. The existing detection method usually adopts the manual detection method. After the plastic pipe is sealed, it is completely immersed in water to observe whether bubbles are generated. If no bubbles are generated, the air tightness is good. If bubbles are generated, further inspection is required.

上述专利虽然公开了一种气密性检测装置，但是遇到管道检测时由于一般气泡较小，通过人工的方式会出现未能及时发现的情况，从而影响工作效率，检测数据不准确，且不会使用多种不同直径管道的检测使用灵活性不够，同时针对小型的检测管需要大型的检测筒，增压时间也比较久，检测时间长等问题。Although the above patent discloses an air tightness detection device, when encountering pipeline detection, since the bubbles are generally small, they may not be discovered in time through manual methods, which affects work efficiency, inaccurate detection data, and is not flexible enough to detect multiple pipelines with different diameters.
