Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring equipment, and particularly relates to a sealing performance detection device for sealing rings. Background Art

[0002] The existing sealing performance detection devices for sealing rings usually adopt a direct pressing method for installation and testing. This method is simple and has a low cost, and is suitable for small batch production or laboratory environments. However, with the increasing requirements for efficiency and precision in industrial production, some limitations of the direct pressing method gradually emerge. Direct pressing will cause pressure concentration at specific points or areas, resulting in over-compression of the pressure-concentrated part of the sealing ring, which will affect the accuracy of the detection results. Therefore, we propose a sealing performance detection device for sealing rings. Content of the Utility Model

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the utility model belong to the scope of protection of the utility model.

[0025] Referring to the attached Figures 1-5, A sealing performance detection device for a sealing ring, comprising a frame body 1. A partition plate 2 is installed on the frame body 1 to divide the frame body 1 into upper and lower parts, forming a water storage area 11 below in the frame body 1, and an installation area above the frame body 1. A cylinder 21 is installed in the middle of one side of the installation area on the partition plate 2. The output end of the cylinder 21 is also connected to a platform 3. The cylinder 21 drives the platform 3 to slide on the partition plate 2. A slide rail installed on the partition plate 2 and a slider installed on the platform 3 are in sliding fit. A plurality of test plates 22 are also installed on the partition plate 2. The test plates 22 are equidistantly distributed and arranged in sequence in the direction of the output end of the cylinder 21. Test holes 23 for accommodating test tubes 4 are formed in the test plates 22. A plurality of pressing plates 31 are sequentially arranged on the platform 3. Grooves are formed on both sides of the notch of the pressing plate 31. A roller 32 is connected in the groove. The number of pressing plates 31 matches the number of test plates 22. A pressure ring 41 is sleeved on the test tube 4. When the test starts, a sealing ring 42 is sleeved on the test tube 4 below the pressure ring 41. The gap left between the pressing plate 31 and the test plate 22 can accommodate the pressure ring 41 and the sealing ring 42. The test tube 4 is placed in the test hole 23. At this time, the sealing ring 42 stays on the surface of the test hole 23. The cylinder 21 is pushed to drive the platform 3 to push the pressing plate 31. The notch of the pressing plate 31 is adapted to the test tube 4. When the pressing plate 31 approaches the test tube 4, the test tube 4 stays in the notch of the pressing plate 31. The rollers 32 connected to both sides of the notch of the pressing plate 31 roll on one side of the pressure ring 41. At this time, one side of the sealing ring 42 enters the test hole 23. The cylinder 21 continues to push, and the rollers 32 roll from one side of the pressure ring 41 to the other side, completely pressing the sealing ring 42 into the test hole 23. Then, high-pressure gas or liquid is introduced into the test tube 4 to test whether the connection between the test tube 4 and the test hole 23 leaks air or water. The water storage area 11 at the bottom of the partition plate 2 is used for receiving. During the whole process, pressure is continuously applied. By rolling from one side to the other side, the pressure is gradually increased, reducing local stress concentration, thereby reducing the risk of damage to the sealing ring material. Moreover, adopting this unified pressing-in method of rolling is easy to standardize, helps to maintain the consistency of product quality, and simplifies the quality control process.
