Description

Technical Field

[0001] This utility model relates to the field of flange gasket testing devices, and more particularly to a flange gasket crack resistance testing device. Background Technology

[0002] Flange gasket testing equipment is a specialized device used to evaluate the sealing performance and structural stability of flange gaskets under simulated actual working conditions. The crack resistance testing device focuses on the gasket's ability to resist cracking. It applies continuous or cyclic loads to the gasket by simulating preload and temperature changes in pipeline connections, while simultaneously monitoring for crack formation and crack propagation. This allows it to determine the gasket's crack resistance limit and durability under pressure, temperature, and other factors, providing data support for flange gasket quality inspection, selection, and safe operation, thus ensuring the sealing and safety of the pipeline system.

[0003] However, the current flange gasket crack detection device has the following defects: First, the clamping range is limited, making it difficult to adapt to flange gaskets of different sizes, and its versatility is insufficient; second, it is inconvenient to observe, lacking some structures that facilitate observation, such as magnifying glasses, and the observation range of some structures that do have observation is limited, affecting the staff's observation effect on gasket cracks. In response to this technical problem, this application proposes a flange gasket crack resistance testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flange gasket crack resistance testing device. The device is designed to clamp flange gaskets of different sizes, improve its versatility, and facilitate observation by workers and expand the observation range through the use of a magnifying glass and a lighting lamp.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A flange gasket crack detection device includes a base and four columns. Hydraulic jacks are mounted on the tops of the four columns, and pressure plates are fixedly connected to the drive ends of the hydraulic jacks. A sliding groove is formed in the middle of the top side of the base, and a flange gasket is disposed on the top side of the base. A round rod is fixedly connected inside the sliding groove, and two clamping plates are slidably connected to the outer wall of the round rod. A rubber pad is fixedly connected to one side of each clamping plate, and a positioning component is provided on the other side of each clamping plate to fix the clamping plates. An annular groove is formed on the outer periphery of the top side of the base, and a cylinder is slidably connected inside the annular groove. An observation component is provided at the top of the cylinder to observe cracks in the flange gasket.

[0006] Furthermore, the positioning component includes a ring rotatably connected to the other side of the clamping plate. The ring is sleeved on the outer wall of the round rod, and a limiting rod is fixedly connected to the outer wall of the ring. A plurality of limiting grooves are provided on one side of the slide groove, and the limiting rod is engaged inside the limiting groove.

[0007] Furthermore, the limiting rod has a cavity inside, a telescopic rod is fixedly connected inside the cavity, an insertion rod is fixedly connected to the end of the telescopic rod, the insertion rod is slidably connected inside the cavity, and a slot is opened inside the limiting groove, the end of the insertion rod is inserted into the slot.

[0008] Furthermore, a spring is fitted on the outer wall of the telescopic rod, one end of the spring is connected to the inside of the cavity, and the other end of the spring is connected to the end of the insertion rod. A lever is fixedly connected to the outer wall of the insertion rod, and the lever is slidably connected to the inside of the limiting rod.

[0009] Furthermore, the observation assembly includes a fixed tube fixedly connected to the top of the cylinder, a sliding rod slidably connected inside the fixed tube, and a magnifying glass rotatably connected to the end of the sliding rod via a damping shaft.

[0010] Furthermore, the outer wall of the slide rod has two grooves that mate with the inner wall of the fixing tube. The inside of the fixing tube is rotatably connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to the inside of the slide rod.

[0011] Furthermore, a knob is rotatably connected to the end of the fixed tube via a damping shaft, the end of the threaded rod is fixedly connected to the inside of the knob, a shaping hose is fixedly connected to the outer wall of the cylinder, and a lighting lamp is fixedly connected to the end of the shaping hose.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the distance between the two clamping plates is adjusted by sliding the clamping plates, so that the device can clamp flange gaskets of different sizes, improving the versatility of the device. Then, the ring is rotated to make the limiting rod rotate into the limiting groove, and at the same time, the spring causes the insertion rod to be inserted into the slot, thereby fixing the limiting rod into the limiting groove, and thus fixing the position of the clamping plate.

[0013] 2. In this utility model, the threaded rod is rotated by turning the knob. Due to the groove on the outside of the slide bar, the threaded rod drives the slide bar to slide, thereby adjusting the position of the magnifying glass so that the magnifying glass can move closer to or further away from the flange gasket. At the same time, the angle of the magnifying glass can be adjusted by rotating the magnifying glass. Simultaneously, the magnifying glass can be moved around the flange gasket by sliding the cylinder, thereby allowing for multi-angle observation of cracks in the flange gasket, which facilitates observation by the staff and expands the observation range.

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.

[0017] Reference Figure 1 and Figure 2This utility model provides an embodiment of a flange gasket crack resistance testing device, comprising a base 4 and four columns 1. Hydraulic jacks 2 are mounted on the tops of the four columns 1. A pressure plate 3 is fixedly connected to the drive end of the hydraulic jacks 2. A sliding groove is formed in the middle of the top side of the base 4, and a flange gasket 5 is disposed on the top side of the base 4. The hydraulic jacks 2 drive the pressure plate 3 to move downwards, causing the pressure plate 3 to compress the flange gasket 5, thereby performing crack resistance testing. An external hydraulic control system is provided for the device. The hydraulic control system includes a manual hydraulic pump and a high-pressure oil pipe. The hydraulic pump is placed on the ground and connected to the cylinder of the hydraulic jacks 2 via the high-pressure oil pipe. A pressure sensor is installed at the connection between the hydraulic jacks 2 and the high-pressure oil pipe. The signal from the pressure sensor is connected to a digital display instrument to display the loading pressure in real time. A round rod 6 is fixedly connected inside the chute. Two clamping plates 7 are slidably connected to the outer wall of the round rod 6. A rubber pad 8 is fixedly connected to one side of the clamping plate 7. The clamping plates 7 are used to clamp the flange gasket 5, and the rubber pad 8 is used to reduce damage to the flange gasket 5 caused by the clamping plates 7. An annular groove is formed on the outer periphery of the top side of the base 4. A cylinder 9 is slidably connected inside the annular groove. (Refer to...) Figures 2-4 On the other side of the clamping plate 7, a ring 11 is rotatably connected. The ring 11 is sleeved on the outer wall of the round rod 6. A limit rod 12 is fixedly connected to the outer wall of the ring 11. Multiple limit grooves are opened on one side of the slide groove. The limit rod 12 is engaged inside the limit groove. A cavity is opened inside the limit rod 12. A telescopic rod 15 is fixedly connected inside the cavity. An insertion rod 13 is fixedly connected to the end of the telescopic rod 15. The insertion rod 13 is slidably connected inside the cavity. A slot is opened inside the limit groove. The end of the insertion rod 13 is inserted into the slot. A spring 16 is sleeved on the outer wall of the telescopic rod 15. One end of the spring 16 is connected to the inside of the cavity. The other end of the spring 16 is connected to the end of the insertion rod 13. A lever 14 is fixedly connected to the outer wall of the insertion rod 13. The lever 14 is slidably connected to the limit rod 15. Inside the rod 12, the distance between the two clamping plates 7 is adjusted by sliding the clamping plates 7, so that the device can clamp flange gaskets 5 of different sizes, improving the versatility of the device. Then, the ring 11 is rotated to make the limiting rod 12 rotate into the limiting groove. At the same time, under the action of the spring 16, the insertion rod 13 is inserted into the slot, thereby fixing the limiting rod 12 into the limiting groove, and thus fixing the position of the clamping plate 7. When it is necessary to remove the limiting rod 12 from the limiting groove, first move the lever 14 to make the insertion rod 13 overcome the resistance of the spring 16 and thus remove it from the slot. Then, by pinching the lever 14, the limiting rod 12 is moved to remove the limiting rod 12 from the limiting groove. The spring 16 is of the type with large elastic potential energy to prevent the insertion rod 13 from leaving the slot due to vibration or other factors.

[0018] Reference Figure 2 , Figure 5 and Figure 6A fixed tube 10 is fixedly connected to the top of a cylinder 9. A slide rod 17 is slidably connected inside the fixed tube 10. A magnifying glass 18 is rotatably connected to the end of the slide rod 17 via a damping shaft. Two grooves are formed on the outer wall of the slide rod 17, which fit into the inner wall of the fixed tube 10. A threaded rod 21 is rotatably connected inside the fixed tube 10, and the outer wall of the threaded rod 21 is threaded into the inside of the slide rod 17. A knob 22 is rotatably connected to the end of the fixed tube 10 via a damping shaft. The end of the threaded rod 21 is fixedly connected to the inside of the knob 22. A shaping hose 19 is fixedly connected to the outer wall of the cylinder 9, and a light 20 is fixedly connected to the end of the shaping hose 19. Rotating the knob 22 causes the threaded rod 21 to rotate. Due to the grooves on the outside of the slide rod 17, the threaded rod 21 drives the slide rod 17. The position of the magnifying glass 18 can be adjusted by sliding it, allowing it to move closer to or further away from the flange gasket 5. The angle of the magnifying glass 18 can also be adjusted by rotating it. Furthermore, the magnifying glass 18 can be moved around the flange gasket 5 by sliding the cylinder 9, enabling multi-angle observation of cracks in the flange gasket 5. A light source is provided by the illumination lamp 20. The position of the illumination lamp 20 can be adjusted by pulling the shaping hose 19. The shaping hose 19 is made of a metal spiral or nested structure, with an outer layer possibly wrapped in plastic or rubber. Utilizing the plasticity of metal, it can be bent at any angle and maintain its shape stably after bending without the need for additional locking devices. This makes it ideal for scenarios requiring flexible position adjustment, such as the lamp arm of a desk lamp or a microphone stand.

[0019] Working principle: First, place the flange gasket 5 on the base 4, then slide the clamping plate 7 to move it closer to the flange gasket 5, thus clamping the flange gasket 5. Next, press the lever 14 to make the insertion rod 13 overcome the resistance of the spring 16 and retract into the cavity. Then, rotate the rotating ring 11 to make the limiting rod 12 rotate into the limiting groove. After that, release the lever 14 so that the insertion rod 13 is inserted into the slot under the action of the spring 16. Then, start the hydraulic jack 2, which drives the pressure plate 3 to move downward, so that the pressure plate 3 squeezes the flange gasket 5, thereby performing crack resistance testing. At the same time, the surface of the flange gasket 5 is observed through the magnifying glass 18. To inspect for cracks on the surface, the threaded rod 21 can be rotated by turning the knob 22. Due to the groove on the outside of the slide rod 17, the threaded rod 21 will drive the slide rod 17 to slide, thereby adjusting the position of the magnifying glass 18 so that the magnifying glass 18 can move closer to or further away from the flange gasket 5. At the same time, the angle of the magnifying glass 18 can be adjusted by rotating the magnifying glass 18. Simultaneously, the magnifying glass 18 can be moved around the flange gasket 5 by sliding the cylinder 9, thereby allowing for multi-angle observation of cracks on the flange gasket 5. The illumination lamp 20 provides a light source, and the position of the illumination lamp 20 can be adjusted by pulling the shaping hose 19.
