DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 5 As shown, the utility model discloses a gasket corrosion resistance test device, including a test box 11, wherein at least two test chambers 12 and a corresponding treatment pool 13 containing an absorbent are respectively opened in the test box 11, and the upper end of the test chamber 12 is connected with a delivery pipe 14 for delivering the test gas (it should be noted here that the delivery pipe 14 is externally connected to a gas tank and a control valve, which is not the focus of this embodiment, so it is not drawn in the example figure and will not be described in detail later), and the lower end of the test chamber 12 is fixedly connected to There is a lower connecting platform 18, and a hanger 15 is detachably connected between the lower connecting platform 18 and the conveying pipe 14. A plurality of hooks 22 for hanging the samples to be tested are fixedly connected to the side wall of the hanger 15, and an anti-slip inclined rod 30 is fixedly connected to the outer end of the hook 22, so that the samples to be tested are not easy to fall off from the hook 22. A ventilation groove 23 is axially penetrated by the hanger 15, and a plurality of flow holes 31 are opened on the side wall of the hanger 15. The test chamber 12 is provided with a pumping mechanism connected to the processing pool 13.

[0026] The working principle of the utility model is as follows: the gasket to be tested is hung on the hook 22, and then the door of the detection box 11 is closed (the inner side of the door is sealed and leakproof, not shown in the figure) to ensure sealing, and then different test gases are respectively introduced into each of the test chambers 12, and the test chambers 12 are filled with test gases, and after the test sample is allowed to stand in the test chamber 12 for a certain period of time, the test gas is pumped into the treatment pool 13 through the pumping mechanism for harmless treatment, and after the test gas content in the test chamber 12 is ensured to be reduced to a safe level, the sample to be tested is taken out of the test chamber 12 and the corrosion condition of its surface is observed and compared.

[0027] The specific connection method of the lower connecting platform 18 and the bracket 15 is as follows: an elastic seat 19 is placed in the lower connecting platform 18, and the elastic seat 19 includes a connecting seat 20 and an elastic pad 21, wherein the elastic pad 21 is annular to facilitate the passage of the test gas, and a plurality of deformation holes are opened on the side wall of the elastic pad 21;

[0028] The elastic pad 21 is placed in the lower connecting platform 18 , the connecting seat 20 is fixedly connected to the upper end of the elastic pad 21 , and the connecting seat 20 is inserted into the lower end of the ventilation groove 23 .

[0029] When installing the hanger 15, first align the lower end of the ventilation groove 23 with the connecting seat 20 so that the connecting seat 20 is inserted into the lower end of the ventilation groove 23. During this process, the operator can press the elastic pad 21 downward so that the connecting seat 20 can be smoothly inserted into the ventilation groove 23, and avoid the upper end of the ventilation groove 23 from colliding with the connecting pipe 17, resulting in damage to the connecting pipe 17 and the hanger 15.

[0030] After the lower end of the hanger 15 is installed, the operator aligns the upper end of the hanger 15 with the connecting pipe 17 and stops squeezing the elastic pad 21. The elastic pad 21 returns to its original position and rebounds to drive the upper end of the hanger 15 to be inserted into the connecting pipe 17, thereby achieving the purpose of fixing the hanger 15.

[0031] The above structure makes the assembly and disassembly operation of the hanger 15 simple and convenient, so that the operator can perform regular replacement, maintenance and cleaning of the hanger 15 .

[0032] In addition, a plurality of limit sliders 28 are fixedly connected to the lower end side wall of the connecting seat 20 , and a limit groove 29 corresponding to the limit slider 28 is opened on the inner side wall of the lower connecting platform 18 , and the limit slider 28 is slidably connected in the limit groove 29 .

[0033] Through the above structure, the stability of the connection between the connecting seat 20 and the lower connecting platform 18 can be enhanced, and the elastic pad 21 can be ensured to be evenly stressed when squeezed, thereby preventing the elastic pad 21 from being damaged due to long-term uneven stress, thereby extending the service life of the elastic pad 21.

[0034] The specific connection method between the delivery pipe 14 and the hanger 15 is as follows: the lower end of the delivery pipe 14 is fixedly connected to a disc, a ventilation cavity 16 connected to the hollow delivery pipe 14 is provided in the disc, a plurality of ventilation holes 32 are provided through the side wall of the ventilation cavity 16, a connecting pipe 17 is fixedly connected to the lower end of the ventilation cavity 16, and the upper end of the hanger 15 is inserted into the connecting pipe 17;

[0035] The test gas in the delivery pipe 14 is divided into two parts. One part is diffused through the vent hole 32 and fills the test cavity 12, and the other part enters the vent groove 23 and diffuses through the through hole 31 in the test cavity 12. On the one hand, the diffusion speed of the test gas in the test cavity 12 is accelerated, and on the other hand, it is ensured that the sample to be tested hung on the hook 22 can be fully in contact with the test gas, so as to ensure the accuracy of the test result and reduce the error.

[0036] The specific structure of the pumping mechanism is as follows: the pumping mechanism includes a pumping tube 24, an electric control valve 25 and an air pump 26, wherein the electric control valve 25 and the air pump 26 are both fixedly connected to the pumping tube 24;

[0037] The pumping pipe 24 is fixedly connected to the lower end of the lower connecting platform 18 and extends through the processing pool 13, and a branch pipe 27 is fixedly connected to the pumping pipe 24, and the branch pipe 27 extends into the test chamber 12. The electric control valve 25 and the air pump 26 are fixedly connected below the branch pipe 27.

[0038] When the test sample is tested, the operator opens the electric control valve 25 and the vacuum pump 26, and the vacuum pump 26 draws all the test gas in the test chamber 12 and the ventilation groove 23 into the treatment pool 13. The test gas reacts with the absorbent in the treatment pool 13, thereby rendering it harmless.

[0039] It should be noted that a pressure gauge is installed in the test chamber 12 so that the operator can observe the pressure change in the test chamber 12 in real time, thereby judging the diffusion degree of the test gas and ensuring that the pressure in the test chamber is at a safe value to ensure the safety of the experiment. Since this is a well-known technology for those skilled in the art, it is not shown in the figure and will not be described in detail in the specification.

[0040] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
