Technical Field

[0001] This utility model relates to the technical field, and in particular to a pressure testing device for a tee fitting. Background Technology

[0002] A pipe fitting with three openings is called a tee. Existing pressure testing devices for tee fittings are generally used to test air tightness in water. The air tightness and pressure condition are judged by observing the generated bubbles. This pressure testing method is extremely inconvenient. First, it is inconvenient to observe the air tightness and pressure when judging air tightness and pressure by bubbles. Second, after completing the air tightness test, the tee needs to be dried before entering other testing procedures, which increases the number of steps and reduces the efficiency of the experiment.

[0003] In the prior art, patent (CN212180202U) proposes a three-way pipe pressure testing device. A first column and a second column are installed on the base, and a top plate is mounted on the top of the two columns. A first tightening device is installed on the top plate. This utility model three-way pipe pressure testing device can realize the use of three-way pipes of various sizes through the design of the screw and motor inside the column. It eliminates the need for air tightness testing in water, making the experimental data more accurate and easier to observe. It also saves the drying process and improves the testing efficiency.

[0004] However, in the aforementioned prior art, the position of the clamping device at the bottom of the base is relatively fixed, making it inconvenient to adjust and move. When adapting to a T-shaped pipe, adjustment is only possible through the other two clamping devices, which limits its use. Summary of the Invention
