[0042] As Figure 6 shown, the specific test process for operating the device of the present utility model is as follows:

[0043] 1. Press the power button 14 to power on and start the device of the present utility model, and hold the device of the present utility model with both hands to dock the flange sleeve port on the isolator or other devices; identify the electronic tag through the induction coil inside the device, automatically read the corresponding number, and conduct online communication.

[0044] 2. While holding the device with both hands, press the start-stop button 16, and one of the solenoid valves in the airtight pump and the solenoid valve group starts to work. After passing through the intake air filter, according to the pre-set airtight pressure value, continuously inflate the cavity of the inflatable sealing strip 9 until the pressure sensor for testing the inflatable sealing strip 9 detects that the pressure in the cavity of the inflatable sealing strip 9 reaches the preset value, then the airtight pump and the working solenoid valve will stop working. During this period, the air release solenoid valve always remains closed. At this time, the device of the present utility model has been closely fitted with the flange sleeve port on the relevant device, and the holding posture with both hands can be released.

[0045] 3. Next, the inflating air pump and the other solenoid valve will also start to work. After passing through the intake air filter, according to the pre-set inflation pressure value, continuously inflate the glove cavity until the other pressure sensor detects that the pressure in the glove cavity reaches the preset value, then the inflating air pump and this solenoid valve will stop working. During this period, the air release solenoid valve always remains closed.

[0046] 4. After the glove cavity undergoes a pressure stabilization stage of t 1 min and a test stage of t 2 min, the second control circuit board will, according to the pre-set logical judgment program, judge the leakage degree trend of the current glove within the t 2 min test time: if the leakage degree trend meets the set threshold, it is qualified; if the leakage degree trend does not meet the set threshold, it is unqualified. Whether the test is qualified or unqualified, the result will be displayed on the display screen 13.

[0047] 5. Finally, hold the device of the present utility model with both hands. By pressing the start-stop button 16, the air release solenoid valve starts to work, and the pressure in the cavity of the inflatable sealing strip 9 is released. After the pressure release is completed, the device of the present utility model can be detached from the flange sleeve port on the isolator or other equipment, and the single test process ends.
