Description

Technical Field

[0001] This utility model relates to the field of valve tensile testing technology, and in particular to a valve tensile testing fixture. Background Technology

[0002] Valves are widely used in the on / off control of pipeline systems in industrial plants such as petroleum, chemical, coal chemical, polysilicon, and power. With industrial development, the operating conditions of valves are becoming increasingly demanding, thus requiring higher quality control in valve manufacturing. This necessitates tensile testing of valves to assess their quality. Traditional valve tensile testing fixtures have some drawbacks. During the valve tensile testing process, workers need to first fix the valve onto a special fixture and then connect it to the testing equipment. The current operating procedure requires workers to perform multiple repetitive steps to complete the fixing and connection, which not only consumes a lot of operating time but also reduces the overall work efficiency of valve tensile testing.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-4As shown, a valve tensile testing fixture includes a testing platform 1. A testing auxiliary mechanism 5 is provided at the upper end of the testing platform 1. The testing auxiliary mechanism 5 includes a fixed frame 51 fixedly connected to the upper end of the testing platform 1. A hydraulic cylinder 52 is fixedly connected to the front end of the fixed frame 51. A connecting plate 53 is installed at the telescopic end of the lower end of the hydraulic cylinder 52. A slide rod 54 is slidably connected inside the connecting plate 53. A pulling frame 55 is fixedly connected to the lower end of the connecting plate 53. A protective pad 56 is fixedly connected to the inner side of the pulling frame 55. A placement frame 57 is fixedly connected to the front side of the upper end of the testing platform 1 near the fixed frame 51. An internal threaded ring 58 is threadedly connected to the outer side of the placement frame 57. A limiting ring 59 is fixedly connected to the upper end of the internal threaded ring 58. A snap-fit ​​pad 510 is fixedly connected to the inner side of the limiting ring 59.

[0015] In this embodiment, a limiting seat 511 is fixedly connected to the front end of the placement rack 57, and a limiting rod 512 is threadedly connected to the inner side of the limiting seat 511. The limiting rod 512 passes through the interior of the placement rack 57 and is threadedly connected to the placement rack 57. A contact block 513 is fixedly connected to the rear end of the limiting rod 512. The upper end of the slide rod 54 is fixedly connected to the top of the inner side of the fixed rack 51. The protective pad 56 is located above the limiting ring 59. The main body material of the protective pad 56 is rubber. The center lines of the placement rack 57, the internal threaded ring 58, the limiting ring 59, and the snap pad 510 are located on the same straight line. The main body material of the snap pad 510 is rubber. The contact block 513 is located inside the placement rack 57. The main body material of the contact block 513 is rubber. There are three sets of limiting seats 511, limiting rods 512, and contact blocks 513.

[0016] Specifically, the worker first places the internal threaded ring 58 on the outside of the valve, causing the locking pad 510 to contact the valve surface. Then, the valve gate is secured inside the pull bracket 55, and the valve is moved downwards until it is inserted into the placement bracket 57, with the valve gate contacting the protective pad 56. Next, the internal threaded ring 58 is rotated, screwing it onto the outside of the placement bracket 57, causing the retaining ring 59 to engage with the valve, thus firmly securing the valve within the placement bracket 57. Then, the hydraulic cylinder 52 is activated, pulling the connecting plate 53 upwards. The connecting plate 53 moves smoothly upward along the slide bar 54, thereby lifting the valve gate of the pull frame 55 upward, allowing for tensile testing of the valve and thus testing its quality. By placing the internal threaded ring 58 on the outside of the valve, locking the valve gate into the pull frame 55, inserting the valve into the placement frame 57, and screwing the internal threaded ring 58 onto the outside of the placement frame 57, the valve can be easily confined on the testing table 1 and locked onto the pull frame 55, thereby reducing the number of steps for workers and improving the efficiency of valve testing.

[0017] In this embodiment, a support base 2 is fixedly connected to the lower end of the testing platform 1, and a storage box 3 is fixedly connected to the front end of the testing platform 1. A controller 4 is installed on the side of the front end of the testing platform 1 near the storage box 3. The controller 4 is electrically connected to the hydraulic cylinder 52.

[0018] Specifically, the hydraulic cylinder 52 can be easily operated by the controller 4, and the support base 2 can provide stable support for the testing table 1.

[0019] Working principle: In use, the worker first places the internal threaded ring 58 on the outside of the valve, causing the locking pad 510 to contact the valve surface. Then, the valve gate is secured inside the pull bracket 55, and the valve is moved downwards until it is inserted into the placement bracket 57, with the valve gate contacting the protective pad 56. Next, the limiting rod 512 is turned, causing it to push the contact block 513 to contact the valve, thus securing the valve within the placement bracket 57. Finally, the internal threaded ring 58 is rotated, screwing it onto the outside of the placement bracket 57, and the limiting ring 59 is secured to the valve, firmly securing the valve within the placement bracket 57. Then, the hydraulic cylinder 52 is activated, which pulls the connecting plate 53 upward, causing the connecting plate 53 to move smoothly upward along the slide rod 54. This causes the pulling frame 55 to lift the valve gate, allowing for a tensile test on the valve and thus testing its quality. By placing the internal threaded ring 58 on the outside of the valve and securing the valve gate into the pulling frame 55, and then inserting the valve into the placement frame 57 and screwing the internal threaded ring 58 onto the outside of the placement frame 57, the valve can be easily secured on the testing table 1 and locked onto the pulling frame 55, thereby reducing the number of steps for workers and improving the efficiency of valve testing.
