Description

Technical Field

[0001] The utility model relates to the technical field of condenser tube detection, and particularly relates to a sealing test device for a condensation spring tube. Background Technique

[0002] A condenser tube is a laboratory device used to promote the condensation effect, which plays a role in condensation or reflux. It usually consists of two glass tubes, one inside the other, with the smaller glass tube passing through the larger one. It is a glass instrument that uses the principle of heat exchange to cool and condense condensable gases into liquids.

[0003] The existing Chinese utility model patent with the reference publication number: CN210689956U discloses a sealing test device for a condenser tube, including a base. A detection pool is fixedly installed at the top of the base. An air inlet pipe that penetrates and extends into the interior of the detection pool is fixedly installed on the right side of the detection pool. A pressure relief valve is fixedly installed at the top of the air inlet pipe and on one side outside the detection pool. A gas pump is fixedly installed at the top of the base and on the right side of the detection pool. The output end of the gas pump is fixedly installed with a connecting pipe that extends into the interior of the air inlet pipe. Fixing hoops are movably installed at the top and bottom on the right side of the air inlet pipe. The rear sides of the two fixing hoops are movably connected through a connecting shaft. Fixing blocks are fixedly installed on the front sides of the two fixing hoops. This sealing test device for a condenser tube solves the problem that the existing sealing test device for a condenser tube is very inconvenient for installing and disassembling the condenser tube, and both require a lot of time for installation and disassembly, which is very wasteful of detection time and energy.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the existing technology, it is found that when the traditional condensation spring tube is subjected to a sealing test, the spring tube is directly fixed at the upper end of the test device for sealing detection, resulting in the inability to adjust according to different lengths and sizes of the condensation spring tubes in the subsequent process, causing a single detection structure. When detecting the condensation spring tube, it is necessary to convey gas at the air inlet of the condensation spring tube. The traditional air pump is connected to the air inlet through a pipeline, resulting in poor gas sealing at the air inlet in the subsequent process, causing poor subsequent detection effects. The existence of these problems affects the use of the device. Content of the Utility Model
