Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a sealing buffer gasket. Background Technology

[0002] A sealing buffer gasket is a ring-shaped fitting installed at the connection point of components to effectively prevent liquid leakage and mitigate the effects of vibration and impact.

[0003] A sealing buffer gasket is a ring-shaped fitting used for sealing and cushioning. Its basic structure includes a buffer gasket, a sealing gasket, and a mounting assembly. During operation, the mounting assembly secures it in the designated position. The sealing gasket forms a closed space by tightly fitting with the contact surface to prevent leakage. The buffer structure deforms when subjected to vibration or impact, dispersing and absorbing energy, thereby ensuring the sealing effect and mitigating the impact of external forces.

[0004] Existing sealing buffer gaskets have relatively simple positioning structures between internal gaskets and between the external sealing part and the mounting assembly. The internal gaskets are often simply positioned using grooves, which are prone to rotation and displacement during deformation, leading to spring misalignment. This significantly reduces the buffering effect, failing to effectively absorb vibration and mitigate impact, while also weakening the sealing performance. The external sealing part and the mounting assembly rely solely on bolt pre-tightening for initial positioning, which is prone to relative movement, disrupting the seal and weakening the sealing performance. This results in an inability to effectively prevent liquid leakage, causing instability in related equipment and affecting the normal operation of the overall system. Therefore, a sealing buffer gasket is proposed to solve the above problems. Utility Model Content

[0015] 1.

The liquid is guided horizontally by the second guide channel to expand the wetting range of the test paper, which can show the degree of liquid leakage. This avoids liquid waste, environmental pollution and safety accidents caused by failure to detect the leak in time, and improves the safety and reliability of equipment operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Reference Figures 1-3 An embodiment of this utility model includes a sealing ring 1, a positioning block 7 fixedly connected to the top of the sealing ring 1, a spring 8 mounted on the positioning block 7, a buffer ring 2 mounted on the top of the sealing ring 1, a positioning block 9 fixedly connected to the top of the buffer ring 2, a spring 10 mounted on the positioning block 9, a buffer ring 3 mounted on the top of the buffer ring 2, a latch 11 fixedly connected to the top of the buffer ring 3, a spring 12 fixedly connected to the outside of the latch 11, a sealing ring 4 mounted on the top of the buffer ring 3, a leakage detection component 5 disposed on the outside of the sealing ring 4, a positioning block 13 fixedly connected to the top of the sealing ring 4, a positioning block 14 fixedly connected to the bottom of the sealing ring 1, flanges 6 mounted on the bottom of the sealing ring 1 and the top of the sealing ring 4, with mounting holes 19 on the flanges 6, and a mounting hole 19 on the bottom of the buffer ring 2. The device includes a positioning groove 15, a positioning block 7 slidably connected inside the positioning groove 15, a spring 8 whose two ends are fixedly connected to the positioning block 7 and the positioning groove 15 respectively, a buffer ring 3 whose bottom has a positioning groove 16, a positioning block 9 slidably connected inside the positioning groove 16, a spring 10 whose two ends are fixedly connected to the positioning block 9 and the positioning groove 16 respectively, a sealing ring 4 whose bottom has a slot 17, a latch 11 installed inside the slot 17, a spring 12 whose two ends are fixedly connected to the top of the buffer ring 3 and the bottom of the sealing ring 4 respectively, a flange 6 whose bottom has a positioning groove 18, a positioning block 13 and a positioning block 14 slidably connected inside the positioning groove 18, a buffer ring 2 and a buffer ring 3 slidably connected inside the sealing ring 1, and a sealing ring 1 slidably connected inside the sealing ring 4.

[0028] Specifically, when installing the sealing buffer gasket, firstly, move buffer ring 2 horizontally. Buffer ring 2 moves positioning groove 15 horizontally. When positioning groove 15 aligns with positioning block 7, slide buffer ring 2 into sealing ring 1. Spring 8 and positioning block 7 enter positioning groove 15. Then, move buffer ring 3 horizontally. Buffer ring 3 moves positioning groove 16 horizontally. When positioning groove 16 aligns with positioning block 9, slide buffer ring 3 into sealing ring 1. Spring 10 and positioning block 9 enter positioning groove 16. Then, move sealing ring 4 horizontally. Sealing ring 4 moves slot 17 horizontally. When slot 17 aligns with tongue 11, slide sealing ring 1 into sealing ring 4. Tongue 11 enters slot 17. At this time, spring 12 is compressed by sealing ring 4. Next, move flange 6 horizontally, aligning positioning groove 18 of the upper and lower flanges 6 with positioning block 13 respectively. After installing the positioning block 14, the upper and lower flanges 6 are then installed on the sealing rings 1 and 4 respectively. Finally, the upper and lower flanges 6 are installed at the pipe connection using screws through the mounting holes 19, completing the installation of the sealing buffer gasket. The positioning of the internal buffer rings 2 and 3 by the positioning blocks 17, 29 and corresponding positioning grooves 15 and 26 effectively prevents the buffer rings 2 and 3 from shifting after deformation, avoiding misalignment of springs 8 and 10, and improving the stability of the buffering effect of the buffer rings 2 and 3. The positioning between the positioning blocks 313 and 414 and the positioning groove 318 effectively improves the positioning efficiency and accuracy of the flange 6 and the sealing rings 11 and 4, avoiding the offset or misalignment of the sealing rings due to vibration, pressure changes, etc., effectively enhancing the sealing effect and reducing the risk of liquid leakage.

[0029] Reference Figures 1-3 The leakage detection component 5 includes a first guide groove 51, which is opened outside the second sealing ring 4. A second guide groove 52 is opened outside the second sealing ring 4. A test paper 53 is fixedly connected to the outside of the second sealing ring 4. The first guide groove 51 and the second guide groove 52 are set perpendicularly to each other. The test paper 53 is set outside the first guide groove 51 and the second guide groove 52.

[0030] Specifically, when there is a liquid leak at the pipe connection where the sealing buffer gasket is installed, the liquid will flow out from the connection between the flange 6 and the sealing ring 4 through the inside of the sealing ring 2. Then, guided by the guide channel 51, it will flow into the guide channel 51. At this time, the liquid will wet the test paper 53, causing the color of the test paper 53 to change. When the liquid continues to leak, the liquid will flow into the guide channel 2 52 along the guide channel 1 51. The area of ​​the test paper 53 that is wetted will gradually increase as the liquid flows into the guide channel 2 52. Based on the area of ​​the test paper 53 that is wetted, the staff can judge the degree of liquid leakage. By guiding the leaking liquid to wet the test paper 53 through the guide channel 1 51, the staff can intuitively judge whether the liquid in the pipe is leaking and the location of the leak without disassembling the equipment. By guiding the leaking liquid to expand the wetted area of ​​the test paper 53 through the guide channel 2 52, the degree of liquid leakage is intuitively shown. This avoids liquid waste, environmental pollution, and even safety accidents caused by the failure to detect the leak in time, and improves the safety and reliability of equipment operation.

[0031] Working principle: When the sealing buffer gasket needs to be installed, first move buffer ring 2 so that positioning groove 15 aligns with positioning block 7. Then slide buffer ring 2 into sealing ring 1, and spring 8 and positioning block 7 enter positioning groove 15. Next, move buffer ring 3 so that positioning groove 16 aligns with positioning block 9. Then slide buffer ring 3 into sealing ring 1, and spring 10 and positioning block 9 enter positioning groove 16. Next, move sealing ring 4 so that slot 17 aligns with tongue 11. Then slide sealing ring 1 into sealing ring 4, and tongue 11 enters slot 17. At this time, spring 3 12 is compressed by sealing ring 2 4. Next, move flange 6 so that positioning groove 3 18 of upper and lower flange 6 aligns with positioning block 3 13 and positioning block 4 14 respectively. Then install upper and lower flange 6 on sealing ring 1 and sealing ring 2 4 respectively. Finally, use screws to install upper and lower flange 6 at the connection of the pipe through mounting hole 19 to complete the installation of the sealing buffer gasket.

[0032] When there is a liquid leak at the pipe connection where the sealing buffer gasket is installed, the liquid will flow into the guide groove 51 through the inside of the sealing ring 2 4. At this time, the liquid will wet the test paper 53 and cause the test paper 53 to change color. As the liquid continues to leak, the liquid will enter the guide groove 2 52 along the guide groove 1 51. The wetted area of ​​the test paper 53 will gradually increase. The degree of liquid leakage can be judged based on the wetted area of ​​the test paper 53.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
