A high-efficiency interchangeable vacuum silicon tube performance testing device Technical Field

[0001] This utility model relates to a high-efficiency interchangeable vacuum silicon tube performance testing device, belonging to the field of vacuum testing technology. Background Technology

[0002] High-vacuum insulated containers mainly consist of inner and outer containers, with a vacuum partition for insulation. The vacuum partition is primarily achieved by continuously operating a vacuum pump for more than 7 days. Vacuum feedback in high-vacuum insulated containers is mainly transmitted through vacuum silicon tubes. If the vacuum silicon tubes are damaged or the measurements are inaccurate, the true vacuum level of the vacuum partition cannot be accurately reflected. Therefore, performance testing of the vacuum silicon tubes is essential. Existing vacuum silicon tube performance testing devices are cumbersome in structure, inconvenient to install and disassemble, time-consuming, lack sufficient accuracy, and are difficult to use for batch testing. Summary of the Invention

The vacuum pumping unit evacuates the vacuum chamber, and the value on the vacuum detection device is compared with the vacuum degree marked on the vacuum silicon tube to quickly evaluate the performance of the vacuum silicon tube.

[0005] The quick-connect test connector unit is provided in multiple sets, and the multiple sets of quick-connect test connector units are evenly distributed along the axial direction of the vacuum chamber.

[0006] Each of the quick-connect test tube units includes two symmetrically arranged quick-connect test tubes, and a sealing ring is provided at the connection between the quick-connect test tube and the vacuum chamber.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] As shown in Figures 1 and 2, this embodiment of a high-efficiency interchangeable vacuum silicon tube performance testing device includes a vacuum chamber 3. The vacuum chamber 3 is equipped with eight sets of quick-connect test tube units evenly distributed along the axial direction of the vacuum chamber 3.

One KF flange joint 6 is connected to a vacuum pumping unit 8 via a metal flexible hose 7; the other KF flange joint 6 is connected to a vacuum gauge 2, which is signal-connected to a vacuum gauge display 1. The vacuum pumping unit 8 evacuates the vacuum chamber 3, and the vacuum gauge detects the vacuum and feeds back the detection results to the vacuum gauge display, ensuring that the vacuum degree of the vacuum chamber is ≤2×10⁻⁶. -3 The vacuum level indicated on the vacuum tube is compared with the value displayed on the vacuum gauge to quickly evaluate the performance of the vacuum tube. Up to 16 vacuum tubes can be tested simultaneously per batch, with short testing time and high accuracy.
