[0030] As Figures 1-4 shown, this embodiment provides a scuba diving simulation test device, which includes a high-pressure test assembly 1, a low-pressure test assembly 2, a pressure vessel 3, and a solenoid valve 4. The high-pressure test assembly 1 includes a high-pressure pressure regulator 11 and a high-pressure pneumatic valve 12. The low-pressure test assembly 2 includes a low-pressure pressure regulator 21 and a low-pressure pneumatic valve 22. Both the high-pressure pressure regulator 11 and the low-pressure pressure regulator 21 are connected to a gas source 9, and the high-pressure pressure regulator 11 and the low-pressure pressure regulator 21 are used to adjust the intake pressure. The pressure vessel 3 can accommodate liquid and the product to be tested. Both the high-pressure pneumatic valve 12 and the low-pressure pneumatic valve 22 are connected to the pressure vessel 3. The gas source 9, the high-pressure test assembly 1, and the pressure vessel 3 are all connected through gas pipelines to form a high-pressure test branch. The gas source 9, the low-pressure test assembly 2, and the pressure vessel 3 are all connected through gas pipelines to form a low-pressure test branch. The solenoid valve 4 is connected to the low-pressure pneumatic valve 22 and the high-pressure pneumatic valve 12, and can open the low-pressure pneumatic valve 22 or the high-pressure pneumatic valve 12 to introduce gas into the pressure vessel 3, so that the product to be tested is subjected to water pressure.

[0031] Inject liquid such as water into the pressure vessel 3, immerse the product to be tested in the water, and apply gas to the pressure vessel 3 through the high-pressure test assembly 1 or the low-pressure test assembly 2. Specifically, a certain pressure can be applied to the inner cavity or outer surface of the product to be tested, so that the product to be tested is subjected to water pressure, and the water pressure is the same as the water pressure at the diving depth, thereby completing the simulation test.

[0032] By adjusting the high-pressure pressure regulator 11 and the low-pressure pressure regulator 21, the high-pressure test branch and the low-pressure test branch have different pressure test ranges to simulate different water pressures. When high-pressure testing is required, turn on the high-pressure test assembly 1 for testing. When low-pressure testing is required, turn on the low-pressure test assembly 2 for testing. By setting the low-pressure test branch and the high-pressure test branch, the pressure test range can be appropriately increased. Exemplarily, different test modes can be set, such as high-pressure test, low-pressure test, alternating high-pressure test and low-pressure test, etc. Select and turn on the corresponding branch for testing according to different modes, which can meet different water pressure test conditions, facilitate adding test modes, is convenient to use, and improves the test efficiency. The two test branches are connected in parallel, one end is connected to the gas source 9, and the other end is connected to the pressure vessel 3. The structure is simple, there are few components, and it is convenient to assemble. The solenoid valve 4 is used to control the opening and closing of the high-pressure pneumatic valve 12 and the low-pressure pneumatic valve 22, further simplifying the structure and improving the usability.

[0033] In one embodiment, the high-pressure pressure regulator 11 includes a pressure pump 111 and a high-pressure electro-pneumatic proportional valve 112, and the low-pressure pressure regulator 21 includes a pressure regulating valve 211 and a low-pressure electro-pneumatic proportional valve 212. The input ends of the pressure pump 111 and the pressure regulating valve 211 are both connected to the gas source 9. The high-pressure electro-pneumatic proportional valve 112 is arranged between the pressure pump 111 and the high-pressure pneumatic valve 12. The output end of the pressure regulating valve 211 is connected to the low-pressure electro-pneumatic proportional valve 212 and the solenoid valve 4. The pressure is initially regulated by the pressure regulating valve 211 and the pressure pump 111, and the pressure is precisely regulated by the high-pressure electro-pneumatic proportional valve 112 and the low-pressure electro-pneumatic proportional valve 212, so that the pressure of the pressure vessel 3 can be accurately controlled. The proportional valve can realize continuous and stepless adjustment of the gas pressure, increasing the pressure adjustment range. Exemplarily, the pressure pump 111 can increase the intake pressure to 1.5 Mpa, the pressure range of the high-pressure electro-pneumatic proportional valve 112 is 0 to 3 Mpa, and the pressure range of the low-pressure electro-pneumatic proportional valve 212 is 0 to 0.9 Mpa, adaptively adjusting the pressure ranges of the high-pressure electro-pneumatic proportional valve 112 and the low-pressure electro-pneumatic proportional valve 212. A safety pin 23 is provided on the low-pressure test branch. The safety pin 23 realizes overload protection. When the pressure of the low-pressure test branch exceeds a preset value such as 0.8 Mpa, the safety pin 23 acts to cut off the gas path.

The high-pressure pressure regulator 11, the low-pressure pressure regulator 21, and the solenoid valve 4 are all electrically connected to the monitoring system 6.
