[0036] Working principle: When using this device to conduct pressure tests on brake hose assemblies with different media, the two joints of the brake hose assembly can be respectively connected to the two fixed joints 15 to install the brake hose assembly onto this equipment. Then, close the working box 2. The internal situation can be observed through the observation window on the working box 2. First, conduct a liquid test. First, close the second electric valve 13, air pump 10, third electric valve 18, pressure booster valve 20, and exhaust valve 22 through the controller 19. Then, start the liquid booster pump 6. The liquid booster pump 6 pumps out the liquid inside the liquid storage tank 5 through the first connecting pipe 7 and pressurizes it until the liquid reaches a certain pressure. Then, it is sent into the interior of the second connecting pipe 8. When the liquid reaches the second electric valve 13 and the third electric valve 18, it is blocked and cannot enter the corresponding pipelines, and can only enter the interior of the input pipeline 14. It enters the interior of the installed brake hose assembly through the input pipeline 14 and is blocked inside the brake hose assembly by the exhaust valve 22, gradually filling the interior of the brake hose assembly. In this way, a liquid pressure test is conducted on the brake hose assembly. After testing for a certain period of time, observe whether there are any leaks or deformations in the brake hose assembly. After the test is completed, close the liquid booster pump 6, and then start the exhaust valve 22 to discharge the liquid inside the brake hose assembly and make it re-enter the interior of the liquid storage tank 5 through the output pipeline 16. For the liquid that may remain inside the input pipeline 14, the third electric valve 18 can be opened to make it enter the interior of the fourth connecting pipe 17 and re-enter the interior of the liquid storage tank 5. Then, conduct a gas test. Close the first electric valve 9, third electric valve 18, and exhaust valve 22, and start the air pump 10 and pressure booster valve 20. The air pump 10 extracts air through the intake pipeline 11 and then sends the air into the interior of the pressure booster valve 20 through the third connecting pipe 12. The pressure booster valve 20 compresses and boosts the air and then sends it into the interior of the fifth connecting pipe 21. Open the second electric valve 13. Blocked by the first electric valve 9 and the third electric valve 18, it enters the interior of the input pipeline 14 and then continues to enter the interior of the brake hose assembly and is blocked inside the brake hose assembly by the exhaust valve 22 to conduct a gas pressure test on the brake hose assembly. Similarly, after testing for a certain period of time, observe whether there are any leaks or deformations in the brake hose assembly. After completion, open the exhaust valve 22 to discharge the air inside the brake hose assembly.
