DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] Example 1, as Figures 1-2As shown, this utility model provides a technical solution: an air dryer sealing test device, including a test water tank frame 1, an air dryer 2 under test, and a first air storage cylinder 8. The first air storage cylinder 8 and the second air storage cylinder 12 are arranged on both sides of the top of the test water tank frame 1. The air dryer 2 under test is arranged at the middle position of the top of the test water tank frame 1, and an exhaust port 6 is arranged below the air dryer 2. A pin 13 is arranged on the side of the air dryer 2 near the exhaust port 6. One side has air inlets A3, B4, and C5. The output end of the first air reservoir 8 is fitted with a first connecting pipe 7 compatible with air inlet A3, and the inner wall of the first connecting pipe 7 is equipped with a first pressure gauge 9. The output end of the second air reservoir 12 is fitted with a second connecting pipe 10 compatible with air inlet B4, and the inner wall of the second connecting pipe 10 is equipped with a second pressure gauge 11. The outer wall of air inlet C5 is equipped with a sealing plug 14. The inner walls of air inlets A3 and B4 are equipped with features for fixing the first air reservoir 8. The mounting mechanism for the first connecting pipe 7 and the second connecting pipe 10 includes a pull rod 18 and a movable groove 21. Positioning grooves 20 are formed on the outer walls of the first connecting pipe 7 and the second connecting pipe 10. Movable grooves 21 are formed on the inner walls of the air inlets A3 and B4. A pull rod 18, penetrating the positioning groove 20, is installed inside the movable groove 21. An arc-shaped positioning block 19 is installed at the bottom end of the pull rod 18, and the lower part of the arc-shaped positioning block 19 is adapted to the inner wall of the positioning groove 20. A spring 22 is sleeved on the outer wall of the pull rod 18. Furthermore, the bottom end of the spring 22 contacts the top end of the arc-shaped positioning block 19. A shut-off valve is provided on one side of the first air storage cylinder 8 and the second air storage cylinder 12. By pulling the pull rod 18, the arc-shaped positioning block 19 is separated from the positioning groove 20, and the first connecting pipe 7 at the air inlet A3 can be separated from the tested air dryer 2. This structure facilitates the installation and removal of the air inlet A3 and air inlet B4 at the tested air dryer 2, making it easier to conduct the next test of the tested air dryer 2, improving the test speed and accelerating the test efficiency.

[0020] Example 2, as Figures 1-4 As shown, this utility model provides a technical solution: an air dryer sealing test device, including an air inlet A3, an air inlet B4 and an air inlet C5, with a sealing gasket 15 inside. The inner walls of the first connecting pipe 7, the second connecting pipe 10 and the sealing plug 14 are provided with sealing blocks 16 adapted to the sealing gasket 15. An annular threaded sleeve 17 that engages with the outer wall of the air inlet C5 is installed on one side of the sealing plug 14. By adding the sealing plug 14 to the air inlet C5, the annular threaded sleeve 17 engages with the outer wall of the air inlet C5, thereby making the sealing block 16 fit closely with the sealing gasket 15, and thus quickly sealing the positions of the air inlet C5, air inlet A3 and air inlet B4.

[0021] Working principle: first, the external power supply is turned on, the operator first drives the sealing plug 14 with the annular threaded sleeve 17 and the air inlet C5 outer wall engagement, so that the sealing block 16 and sealing gasket 15 inner fit, and then the air inlet C5 fast sealing position, then, start the first air cylinder 8 to the air inlet A3 input air pressure, when the first air pressure gauge 9 and the second air pressure gauge 11 air pressure reaches 810 ± 20 kPa, while the exhaust port 6 automatic exhaust, and through the closing of the second air cylinder 12 stop valve, so that the second air pressure gauge 11 pressure drops to 680 ~ 750 kPa, while the exhaust port 6 should stop exhaust, and through the test water tank frame 1 to add clean water can test the measured air dryer 2 sealing.

[0022] When it is needed to separate the arc-shaped positioning block 19 from the positioning groove 20 by pulling the pull rod 18, the first connecting pipe 7 at the air inlet A3 can be separated from the measured air dryer 2. The structure facilitates the disassembly of the air inlet A3 and the air inlet B4 at the measured air dryer 2. When installation is needed, the first connecting pipe 7 can be inserted into the air inlet A3, so that the outer wall of the first connecting pipe 7 extrudes the arc-shaped positioning block 19, and then the arc-shaped positioning block 19 extrudes the spring 22 to be compressed. The positioning groove 20 at the position of the first connecting pipe 7 is aligned with the arc-shaped positioning block 19. Then, the spring 22 is compressed, so that the arc-shaped positioning block 19 is attached to the positioning groove 20 under the elastic force of the spring 22. The structure facilitates the installation of the first connecting pipe 7 and the air inlet A3, thereby reducing the working time and improving the work efficiency.

[0023] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical solutions of the present application by those skilled in the art do not deviate from the essence and scope of the technical solutions of the present application.
