[0027] Example
[0028] Please see Figures 1-5 This utility model provides a technical solution: a connecting flange with an anti-vibration structure, including a first flange 1 and a second flange 2. One end of the first flange 1 and the second flange 2 are connected to a pipe 4. A rubber pad 3 for anti-vibration is clamped between the first flange 1 and the second flange 2. Several screw holes 6 are opened on one side of the first flange 1, the second flange 2 and the rubber pad 3. Bolts are inserted into the screw holes 6 so that the rubber pad 3 is clamped between the first flange 1 and the second flange 2. Then, nuts and bolts are used to connect the first flange 1 and the second flange 2.
[0029] A warning component 5 is provided on one side of the first flange 1;
[0030] The prompt component 5 includes a first limiting rod 51 and a second limiting rod 52. A limiting frame 511 is fixed to one side of the second limiting rod 52, and a pull rod 54 is fixed to one side of the first limiting rod 51. A slide plate 55 is fixed to one side of the pull rod 54. A slide groove 56 is slidably connected to the outside of the slide plate 55 inside the limiting frame 511. The first flange 1 drives the first limiting rod 51 and the pull rod 54 to move away from the second flange 2. At this time, the pull rod 54 drives the slide plate 55 to slide inside the slide groove 56. An indicator light 53 is installed on one side of the top of the pull rod 54.
[0031] A switch 57 is installed on the inner wall of the slide 56, located on one side of the slide plate 55. The slide plate 55 compresses the spring 58, and at the same time, the slide plate 55 touches the contact of the switch 57, causing the switch 57 to be triggered. The slide plate 55 is cylindrical in shape. The spring 58 is sleeved on the outside of the switch 57. The two ends of the spring 58 are respectively connected to one side of the slide plate 55 and the slide 56. A button battery 59 is installed inside the limit bracket 511. A cover plate 510 located on the side of the button battery 59 is connected to one side of the limit bracket 511 by bolts. When the switch 57 is triggered, the indicator light 53 lights up. At this time, the worker can tell by visually observing that the gap between the first flange 1 and the second flange 2 has increased, and the connection between the first flange 1 and the second flange 2 needs to be inspected.
[0032] The output terminal of the button battery 59 is electrically connected to the input terminal of the switch 57, and the output terminal of the switch 57 is electrically connected to the input terminal of the indicator light 53. The outer side of the first limiting rod 51 is inserted into one side of the first flange 1. The first limiting rod 51 can be inserted and connected by welding or gluing. The outer side of the second limiting rod 52 is inserted into one side of the second flange 2. The second limiting rod 52 can be inserted and connected by welding or gluing. The outer side of the pull rod 54 is sequentially inserted into one side of the second limiting rod 52 and the limiting frame 511.
[0033] Working principle: When it is necessary to connect the first flange 1 and the second flange 2 together, simply connect the pipe 4 to the equipment respectively, insert the bolt into the bolt hole 6 so that the rubber gasket 3 is clamped between the first flange 1 and the second flange 2, and then use nuts and bolts to connect the first flange 1 and the second flange 2. The main function of the rubber gasket 3 is to provide a sealing function to prevent media leakage. Since the rubber material has certain elasticity and damping characteristics, it can also absorb and buffer vibration energy to a certain extent. When the flange connection is subjected to vibration, the rubber gasket 3 can act as a shock-absorbing element to help reduce the transmission of vibration and stress concentration at the flange connection.
[0034] When the bolts connecting the first flange 1 and the second flange 2 loosen, the gap between the first flange 1 and the second flange 2 increases. Subsequently, the first flange 1 moves the first limit rod 51 and the pull rod 54 away from the second flange 2. At this time, the pull rod 54 drives the slide plate 55 to slide inside the slide groove 56. The slide plate 55 compresses the spring 58. At the same time, the slide plate 55 touches the contact of the switch 57, causing the switch 57 to be triggered. When the switch 57 is triggered, the indicator light 53 lights up. At this time, the worker can tell by visually observing the indicator light 53 that the gap between the first flange 1 and the second flange 2 has increased, and the connection between the first flange 1 and the second flange 2 needs to be inspected.
[0035] Remove the bolts connecting one side of the cover plate 510 to replace the button battery 59 inside the limit bracket 511.
[0036] In summary, the rubber gasket 3 is clamped between the first flange 1 and the second flange 2. Its main function is to provide a reliable sealing function and effectively prevent media leakage. Due to its elasticity and damping properties, the rubber material can absorb and buffer vibration energy. When the flange connection is subjected to vibration, the rubber gasket 3 can act as an effective shock absorber, reducing the transmission of vibration and stress concentration at the flange connection, thereby extending the service life of the flange and the pipeline system.
[0037] When the bolts connecting the first flange 1 and the second flange 2 become loose, causing the gap to widen, the contact of the switch 57 is triggered by the slide plate 55, and the indicator light 53 is lit, providing workers with an immediate visual warning. This helps workers quickly identify potential safety hazards and avoid accidents. The illumination of the indicator light 53 directly indicates the specific location that needs to be checked, enabling workers to quickly locate the problem and take action.
