Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, specifically to an automatic assembly, pressure testing and adjustment device for safety valves. Background Technology

[0002] A safety valve is a product commonly used to protect pressure vessels. When an abnormally high pressure condition occurs inside the pressure vessel, the safety valve will open in time to release the pressure and prevent the pressure inside the pressure vessel from continuing to rise, thereby achieving the purpose of protecting the pressure vessel. In the production process, existing safety valves require the use of automatic assembly and pressure testing devices.

[0003] However, existing pressure testing devices cannot filter the air pressure medium entering the pressure testing chamber when testing safety valves. Impurities in the air can easily adhere to the pressure testing chamber and connecting pipes, thus affecting the subsequent use of the device.

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: an automatic assembly, pressure testing, and adjustment device for a safety valve, including a workbench 1, an automatic assembly machine 2 fixedly installed on the upper part of the workbench 1, a mounting bracket 4 fixedly installed on the upper part of the workbench 1, a pressure testing chamber 5 fixedly installed on the upper part of the workbench 1, a pressure pump 6 fixedly installed on the upper part of the workbench 1, and a connecting assembly 3 disposed on the upper part of the workbench 1. The connecting assembly 3 includes a filter mechanism 31 disposed on the upper part of the workbench 1, a fixing mechanism 32 disposed on the upper part of the workbench 1, and the output end of the pressure pump 6 is connected to the pressure testing chamber 5 through an exhaust pipe. The filter mechanism 31 includes a filter box 311 fixedly installed on the upper part of the workbench 1, an air inlet pipe 312 connected to one side of the filter box 311, and an installation groove is opened inside the filter box 311, into which an installation device is inserted. The frame 313 has a filter plate 314 fixedly installed inside it. The inner wall of the filter box 311 is fixedly connected with a sealing ring, which is located in the gap between the frame 313 and the mounting groove. The upper part of the filter box 311 has a sliding groove 315. The inner wall of the sliding groove 315 is fixedly connected with a sliding rod 316. The outer wall of the sliding rod 316 is slidably connected with a slider 317. The inner wall of the sliding groove 315 is fixedly connected with a first spring 318. The upper part of the slider 317 is fixedly connected with a limit rod 319. The filter box 311 has a rectangular groove 3110 inside it. The inner wall of the rectangular groove 3110 is slidably connected with a rectangular column 3111. The inner wall of the rectangular groove 3110 is fixedly connected with a fixing column 3112. The outer wall of the fixing column 3112 is slidably connected with an ejector ring 3113. The inner wall of the rectangular groove 3110 is fixedly connected with a second spring 3114.

[0029] In this embodiment, the air inlet pipe 312 is connected to the input end of the pressure pump 6. One end of the first spring 318 is fixedly connected to the slider 317. The bottom of the limiting rod 319 is attached to the upper part of the mounting frame 313. Through the cooperation of the filter box 311, the air inlet pipe 312, the mounting frame 313, the filter plate 314, the slide groove 315, the slide rod 316, the slider 317, the first spring 318, the limiting rod 319, the rectangular groove 3110, the rectangular column 3111, the fixed column 3112, the ejection ring 3113, and the second spring 3114, the air pressure medium entering the pressure test chamber 5 can be filtered. This can prevent impurities in the air from adhering to the inner wall of the pressure test chamber 5 and the air inlet pipe 312, and can also prevent damage to the pressure sensor 327. At the same time, the mounting frame 313 is easy to disassemble manually, which facilitates manual cleaning of the filter plate 314.

[0030] Furthermore, the rectangular column 3111 is slidably connected to the outer wall of the fixed column 3112, the top end of the second spring 3114 is fixedly connected to the ejector ring 3113, and the rectangular column 3111 is fixedly connected to the mounting frame 313.

[0031] In use, the device uses a pressure pump 6 to introduce air from the filter box 311 into the pressure test chamber 5. As the air passes through the filter box 311, it is filtered by the filter plate 314, preventing impurities from adhering to the inner walls of the pressure test chamber 5 and the air inlet pipe 312, thus avoiding any impact on the device's subsequent use. Furthermore, when the mounting frame 313 needs to be disassembled, it can be easily removed by manually pushing the limiting rod 319, which, under the limiting action of the sliding rod 316 and the slider 317, allows... The limiting rod 319, which is fixedly connected to the upper part of the slider 317, is away from the upper part of the mounting frame 313. Then, under the action of the elastic force of the second spring 3114, the ejector ring 3113 can press the rectangular column 3111 upward. Since the rectangular column 3111 is fixedly connected to the mounting frame 313, the mounting frame 313 can be lifted upward, making it easier to manually remove the mounting frame 313. Then, the filter plate 314 can be cleaned, which can prevent the filter holes of the filter plate 314 from being blocked and affecting subsequent use.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the automatic assembly, pressure testing, and adjustment device for a safety valve provided by this utility model is, for example... Figures 1 to 4 As shown: The fixing mechanism 32 includes a motor 321 fixedly installed on the right side of the test chamber 5 via a base. A bidirectional threaded rod 322 is fixedly connected to the output end of the motor 321. A clamping plate 323 is threadedly connected to the outer wall of the bidirectional threaded rod 322. A fixing rod 324 is fixedly connected to the inner wall of the test chamber 5. A first guide plate 325 and a second guide plate 326 are fixedly connected to the inner wall of the test chamber 5 respectively. A pressure sensor 327 is fixedly installed on the inner wall of the test chamber 5. An electric telescopic rod 328 is fixedly installed at the bottom of the automatic assembly machine 2. A cover plate 329 is fixedly connected to the output end of the electric telescopic rod 328. A sealing gasket is fixedly installed on the upper part of the test chamber 5.

[0034] In this embodiment, the bidirectional threaded rod 322 is rotatably connected to the test chamber 5 via a bearing, and the first guide plate 325 is slidably connected to the outer wall of the fixed rod 324. Through the cooperation of the motor 321, the bidirectional threaded rod 322, the clamping plate 323, the fixed rod 324, the first guide plate 325, the second guide plate 326, the pressure sensor 327, the electric telescopic rod 328, and the cover plate 329, when the assembled safety valve enters the test chamber 5, the safety valve can be clamped and fixed, thereby preventing the safety valve from moving during the pressure test and affecting the detection effect. The pressure sensor 327 is an STG series pressure sensor.

[0035] Furthermore, there are two second guide plates 326, symmetrically distributed within the pressure testing chamber 5.

[0036] After the automatic assembly machine 2 assembles the safety valve, it can transport the safety valve into the mounting frame 4. Then, under the action of the first guide plate 325 and the second guide plate 326, the safety valve can fall into the bottom of the pressure test chamber 5. Then, the motor 321 drives the bidirectional threaded rod 322 to rotate, and under the limiting action of the fixed rod 324, the clamping plate 323 threaded to the outer wall of the bidirectional threaded rod 322 can move towards the middle, thereby clamping and fixing the safety valve, preventing the safety valve from moving during the pressure test and affecting the test results. After the safety valve is fixed, the electric telescopic rod 328 drives the cover plate 329 to move downward, and under the action of the sealing gasket, the pressure test chamber 5 can be sealed. Then, the pressure pump 6 can introduce air pressure medium into the pressure test chamber 5 to perform the pressure test operation.
