Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to a copper tube sealing detection device. Background Art

[0002] Tubes usually refer to tubes made of copper. Such tubes are widely used in musical instruments, industry, and construction. In industry, copper tubes are often used to make wires, pipes, and radiators in electronic equipment. After the copper tube is produced, it is necessary to conduct airtightness testing on the copper tube to ensure the normal use of the copper tube.

[0003] A heat exchanger copper tube sealing detection device mentioned in an existing Chinese public patent (authorization announcement number: CN217483771U) can judge the sealing performance of the heat exchanger copper tube by observing whether bubbles appear in the water. Through structural design, it solves the problem that the test device on the market is not stable enough to fix the heat exchanger copper tube, resulting in gaps in the connection between the heat exchanger copper tube and the two docking modules, causing gas leakage at the interface, thereby misleading personnel into thinking that the gas inside the tube body is leaking. The accuracy of the test results of the device is increased, the steps of the device for testing the sealing of the copper tube are simplified, and the practical performance of the device is increased.

[0004] In the process of existing pipeline sealing detection, it is mostly necessary to place the copper pipe in a water tank and then observe the bubbles in the water tank to judge the air tightness of the copper pipe. Although it is simple and easy, since the copper pipe is in a static state in the water, when the bubbles generated by the copper pipe are small, due to the effect of surface tension, the bubbles may adhere to the surface of the copper pipe to form a film-like structure, so that the bubbles are not completely separated from the surface of the pipe, which may cause inconvenience for the staff to observe, thereby reducing the accuracy of the detection. Utility Model Content

[0005] The purpose of the present application is to provide a copper tube sealing detection device to solve the problem that when the bubbles generated in the copper tube are small, due to the effect of surface tension, the bubbles tend to adhere to the surface of the copper tube, thereby reducing the accuracy of detection.
