This system is designed to accurately test whether the hardness performance of key parts of the valve core meets design standards and safety requirements. It features hardness testing capabilities, stable valve core positioning, and standardized control of the testing process. It is adaptable to the testing needs of valve cores of different specifications. Its core function is to obtain valve core hardness data through scientific testing methods, thereby determining whether the mechanical properties of the valve core material meet standards and can satisfy the long-term pressure-bearing, sealing, and wear-resistant requirements of the safety valve. This provides crucial testing support for quality control and safety performance assurance of safety valve products.

They have poor clamping compatibility, making it difficult to clamp quickly and stably. Furthermore, the test position is inconvenient to adjust, and it is difficult to flexibly select test points, resulting in low testing efficiency and hindering the implementation of batch valve core hardness testing.

[0004] To address this, a valve core hardness testing structure for safety valve production is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A valve core hardness testing structure for safety valve production includes a tester 1. A test platform 3 is provided on the inner wall of the tester 1. A slider 4 is slidably connected to the inner wall of the test platform 3. A positioning mechanism 2 is fixedly connected to the top of the slider 4. A valve core assembly 5 is snapped into the inner wall of the positioning mechanism 2. A limit rod 6 is movably connected to the inner wall of the positioning mechanism 2. The positioning mechanism 2 includes a placement block 201. A replacement block 202 is fixedly connected to the bottom of the placement block 201. A fixing frame 203 is snapped into the surface of the replacement block 202. The bottom of the fixing frame 203 is fixedly connected to the top of the slider 4.

[0029] In this embodiment: By setting a positioning mechanism 2, which supports the valve core assembly 5 through a placement block 201, and utilizing the snap-fit ​​cooperation between the replacement block 202 and the fixing frame 203, the placement test fixture for the valve core assembly 5 can be conveniently replaced. This allows for quick adaptation to valve core assemblies 5 of different specifications, ensuring stable clamping of the valve core assembly 5 and providing a reliable positioning basis for accurate hardness testing of the tester 1. This improves test compatibility and clamping efficiency. By setting a slider 4, the position of the slider 4 and the fixing frame 203 is used to fix the device, facilitating subsequent sliding of the slider 4 on the inner wall of the test bench 3 via the fixing frame 203. This allows for flexible selection of test points, making hardness testing of different parts of the valve core assembly 5 more convenient. Combined with the snap-fit ​​limitation of the valve core assembly 5 by the positioning mechanism 2, this helps to stabilize the testing work and optimizes the flexibility of the testing operation and the smoothness of the testing process.

[0030] Specifically, such as Figure 2 , Figure 5 As shown, the bottom of the fixing bracket 203 contacts the top of the test bench 3, and the inner wall of the placement block 201 is provided with a positioning groove 7 for use with the valve core assembly 5.

[0031] Specifically, such as Figure 4 As shown, the surface of the limiting rod 6 is movably connected to the inner wall of the fixing frame 203, and the surface of the limiting rod 6 is movably connected to the inner wall of the replacement block 202.

[0032] Specifically, such as Figure 3 As shown, the inner wall of the test bench 3 is movably connected to a limit block 8, and the inner wall of the limit block 8 is threaded with a bolt 9.

[0033] In this embodiment: the positioning groove 7 opened on the inner wall of the placement block 201 facilitates the installation of the valve core assembly 5 on the inner wall of the placement block 201 through the positioning groove 7, which facilitates the stable installation of the valve core assembly 5. The surface of the limiting rod 6 is movably connected to the inner wall of the fixing frame 203 and the replacement block 202 respectively, which facilitates the limitation of the position of the replacement block 202 by the limiting rod 6, and avoids the replacement block 202 from shaking unexpectedly during use. By setting the limiting block 8 and the bolt 9, the limiting block 8 is inserted into the inner wall of the test bench 3 during use, and then the bolt 9 is used to rotate on the inner wall of the fixing frame 203 and the limiting block 8, which facilitates the limitation of the position of the fixing frame 203 by the bolt 9, and avoids the fixing frame 203 from shifting during vehicle body operation.

[0034] Specifically, such as Figure 3 As shown, the surface of the bolt 9 is threaded to the inner wall of the fixing frame 203, and the inner wall of the test bench 3 is provided with a limiting groove 10 that cooperates with the limiting block 8.

[0035] Specifically, such as Figure 3As shown, the inner wall of the fixing bracket 203 is provided with a countersunk hole 11 for use with the bolt 9, and the inner wall of the limiting block 8 is provided with a threaded hole 12 for use with the bolt 9.

[0036] In this embodiment: the limiting groove 10 opened on the inner wall of the test bench 3 facilitates the installation of the limiting block 8 on the inner wall of the test bench 3 through the limiting groove 10; the countersunk hole 11 opened on the inner wall of the fixing frame 203 facilitates the rotation of the bolt 9 on the inner wall of the fixing frame 203 through the countersunk hole 11; and the threaded hole 12 opened on the inner wall of the limiting block 8 facilitates the rotation of the bolt 9 on the inner wall of the limiting block 8 through the threaded hole 12, thus facilitating the restriction of the position of the fixing frame 203 by the bolt 9.

[0037] Specifically, such as Figure 6 As shown, a connecting block 13 is fixedly connected to the front side of the fixing frame 203, and a fixing plate 14 is fixedly connected to the front side of the connecting block 13.

[0038] Specifically, such as Figure 6 As shown, a telescopic rod 15 is fixedly connected to the rear side of the fixed plate 14, and a spring 16 is sleeved on the surface of the telescopic rod 15.

[0039] Specifically, such as Figure 6 As shown, a limiting plate 17 is fixedly connected to the rear side of the telescopic rod 15, and the rear side of the limiting plate 17 is fixedly connected to the front side of the limiting rod 6.

[0040] Specifically, such as Figure 6 As shown, a fixing block 18 is fixedly connected to the top of the limiting plate 17, and a pull block 19 is fixedly connected to the top of the fixing block 18.

[0041] In this embodiment: By setting a connecting block 13 and a fixing plate 14, the connecting block 13 and the fixing plate 14 are fixed in use, so that the fixing plate 14 can provide an installation base for the telescopic rod 15. Then, the telescopic rod 15 cooperates with the spring 16 to provide elastic reset power for the limit rod 6. After the pull block 19 is pulled to drive the limit rod 6 to disengage from the replacement block 202 for fixture replacement, the spring 16 can automatically push the limit rod 6 to reset, so as to quickly complete the next limit operation and improve the efficiency of fixture replacement and limit adjustment.

[0042] Working principle: During the use of the tester 1, the positioning mechanism 2 is set up. The positioning mechanism 2 supports the valve core assembly 5 through the placement block 201. By utilizing the snap-fit ​​cooperation between the replacement block 202 and the fixing frame 203, the placement test fixture of the valve core assembly 5 can be easily replaced. It can quickly adapt to valve core assemblies 5 of different specifications, ensure the stable clamping of the valve core assembly 5, and provide a reliable positioning basis for the accurate hardness testing of the tester 1, improving test compatibility and clamping efficiency. By setting up the slider 4, the position of the slider 4 and the fixing frame 203 is fixed during use, which facilitates the subsequent sliding of the slider 4 on the inner wall of the test platform 3 by the fixing frame 203. The test points can be flexibly selected, making the hardness testing of different parts of the valve core assembly 5 more convenient. In conjunction with the snap-fit ​​limit of the valve core assembly 5 by the positioning mechanism 2, it helps to carry out stable testing work, optimizes the flexibility of test operation and the smoothness of the test process.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
