[0002] Oxygen air storage tanks usually refer to pressure vessels used to store oxygen or air (nitrogen and other gases are also possible).

[0003] After production, gas tanks need to be tested for their oxygen storage performance. Usually, oxygen is directly fed into the gas tank, and the oxygen storage performance is tested by observing the changes in the pressure gauge. However, in actual use, the gas supply of the gas tank is variable. The existing technology cannot detect the oxygen storage performance of the gas tank under different oxygen supply states. Therefore, an oxygen storage performance testing device that can adjust the oxygen supply in real time is needed to meet people's needs. Utility Model Content

[0012] The beneficial effects of the utility model are:

[0013] In the utility model, by turning the knob, the screw is rotated, thereby driving the regulating valve to move, causing the deformation of the spring to change. Then, when the air pressure in the gas tank is greater than the elastic force of the spring, the air pressure pushes the valve core away from the fixed ring. The valve core, connected with the push rod, drives the push plate to move, so that the dynamometer displays the pressure required for the valve core to move in this state. After the valve core moves, the gas in the gas tank is discharged from the fixed ring to the second test tube. The change in the valve core movement amount realizes the change in the oxygen supply of the gas tank, and the oxygen supply is displayed via the flow meter. The device realizes the gas storage performance test of the gas tank under different oxygen supply states, and is easy to adjust and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

A push rod 15 is connected to the valve core 9, and a second test tube 16 is connected to the lower end of the first test tube 4, and a flow meter 17 is provided on the second test tube 16.

[0021] Before the test, the air outlet pipe 3 is blocked and the gas is rushed into the gas tank 1, so that the gas generates a certain pressure in the gas tank. By turning the knob 6, the screw 5 is rotated, thereby driving the regulating valve 7 to move, causing the deformation of the spring 8 to change. Then, when the air pressure in the gas tank 1 is greater than the elastic force of the spring 8, the air pressure pushes the valve core 9 away from the fixed ring 10. The valve core 9 drives the push plate 14 to move under the connection of the push rod 15, so that the tension gauge 13 displays the pressure required for the valve core 9 to move in this state. After the valve core 9 moves, the gas in the gas tank 1 is discharged from the fixed ring 10 to the second test tube 16. The change in the movement of the valve core 9 realizes the change of the oxygen supply of the gas tank 1, and the oxygen supply is displayed via the flow meter 17. The device realizes the gas storage performance test of the gas tank 1 under different oxygen supply states, and is easy to adjust and simple to operate.

[0022] Specifically, in this embodiment, the first test tube 4 can be connected to the gas storage tank 1 by a threaded connection, so that the test device can be detached, which is convenient for testing different gas storage tanks 1.

[0023] Specifically, in this embodiment, a positioning ring 18 is connected to the outer wall of the screw 5 located in the end portion of the first test tube 4 to limit the axial displacement of the screw 5 .

[0024] Specifically, in this embodiment, a threaded hole 19 is provided on the regulating valve 7, and the screw 5 is threadedly connected in the threaded hole 19, so that the screw 5 rotates to drive the regulating valve 7 to move, and the stability after adjustment is ensured.

[0025] Specifically, in this embodiment, a limit pin 20 is provided on the end of the screw 5 located in the first test tube 4 to limit the movement and adjustment of the regulating valve 7 and prevent separation from the screw 5 .

[0026] Specifically, in this embodiment, the valve core 9 and the fixing ring 10 are sealed to improve air tightness and prevent air leakage at the contact portion.

[0027] Specifically, in this embodiment, the push rod 15 is slidably connected to the connecting plate 12, the end of the first test tube 4 and the regulating valve 7, providing stability and limiting for the movement of the regulating valve 7, and preventing the regulating valve 7 from rotating in place when the screw 5 rotates.

[0028] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
