Description

Technical Field

[0001] This utility model relates to the field of automotive flange technology, specifically to an automotive flange with good leak-proof performance. Background Technology

[0002] A flange connection involves fixing two pipes, fittings, or equipment to a flange plate, placing a gasket between the two flange plates, and then tightening them together with bolts to complete the connection. Some fittings and equipment already come with flange plates, which also fall under the category of flange connections. Flange connections are an important connection method in pipeline construction because they are convenient to use and can withstand greater pressure.

[0003] Existing flanges include a flange plate, connecting holes evenly spaced on the flange plate, a positioning seat for connecting pipes, and a flange gasket placed between two flange plates. They are typically used for connecting pipes with high pressure. However, there are still some drawbacks to the above technical conditions: when using the above flanges, the pipes to be connected need to be supported and fully aligned with the original pipes before bolting can be used for a better flange connection. This makes the operation of flange connections difficult.

[0004] Therefore, we propose a flange for automobiles with good leak-proof performance. Utility Model Content

[0005] The purpose of this invention is to provide an automotive flange with good leak-proof performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof automotive flange, comprising a flange plate, an insertion groove on the inner circumferential surface of the flange plate, a positioning seat integrally provided on one side of the flange plate, an insertion arc plate integrally provided on the other side of the flange plate opposite to the insertion groove, a sealing convex ring integrally provided on the flange plate located outside the splicing arc plate, a mounting hole provided on the flange plate located outside the positioning seat, a splicing slide groove provided on one side of the insertion arc plate, a splicing slide strip integrally connected to the other side of the insertion arc plate, a sealing wing provided on the outer arc surface of the splicing arc plate, an annular groove provided in the middle of the side of the sealing convex ring, a leak-proof ring fixedly installed inside the annular groove, and a flange gasket provided between the two spliced ​​flange plates.

[0007] Optionally, the thickness of the leak-proof ring is greater than twice the depth of the annular groove, and the inner diameter of the leak-proof ring is greater than the outer diameter of the plug-in arc plate.

[0008] Optionally, the outer diameter of the insertion arc plate is equal to the diameter of the insertion groove, and the length of the insertion arc plate is the same as the depth of the insertion groove.

[0009] Optionally, the cross-section of the splicing slide bar is the same as the cross-section of the splicing slide groove, one end of the splicing slide groove and the splicing slide bar is flush with the bottom of the insertion groove, and the other end of the splicing slide groove and the splicing slide bar is flush with the end of the insertion arc plate.

[0010] Optionally, a positioning block is integrally provided on one side of the flange, located between the mounting holes, and a positioning hole corresponding to the positioning block is provided in the middle of the flange gasket.

[0011] Optionally, the flange gasket and the leak-proof ring are made of nitrile rubber, and the flange gasket can be squeezed and deformed during installation to completely fit the outer peripheral surface of the sealing ring.

[0012] Optionally, the insertion arc plate, insertion groove, and flange are arranged concentrically, and the sealing wing is made of silicone.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This automotive flange with excellent leak-proof performance features a plug-in arc plate and plug-in groove. During installation, the pipe is fixed to the positioning seat of the flange, and then the plug-in arc plates and plug-in grooves of the two flanges are spliced ​​together using splicing slides and splicing strips. At the same time, the silicone sealing wings are tightly sealed against the arc surface of the plug-in groove, so that the plug-in arc plate and plug-in groove seal the connecting hole in the middle of the flange, achieving a good leak-proof effect and increasing the sealing performance of the flange.

[0014] 2. This automotive flange with excellent leak-proof performance, by setting a flange gasket and a leak-proof ring, allows the sealing rings of the two flanges to be sealed again by the leak-proof ring when two flanges are connected. At the same time, the flange gasket is compressed and deformed during installation, so that it can completely fit the outer circumference of the sealing ring. This makes the insertion arc plate and insertion groove, the flange gasket and the leak-proof ring form a triple seal to prevent leakage, greatly improving the sealing performance of the flange.

[0018] Please see Figures 1 to 4 This utility model provides a leak-proof automotive flange, including a flange 1. The inner circumferential surface of the flange 1 has a insertion groove 4. A positioning seat 3 is integrally formed on one side of the flange 1, and an insertion arc plate 5 opposite to the insertion groove 4 is integrally formed on the other side of the flange 1. A sealing convex ring 9 is integrally formed on the outer side of the insertion arc plate. The flange 1 has a mounting hole 2 located outside the positioning seat 3. A splicing slide groove 6 is formed on one side of the insertion arc plate 5, and a splicing slide strip 7 is integrally connected to the other side of the insertion arc plate 5. A sealing wing 8 is provided on the outer arc surface of the splicing arc plate, and a sealing convex ring 9 has a central opening on its side. An annular groove 10 is provided, and a leak-proof ring 11 is fixedly installed inside the annular groove 10. A flange gasket 13 is provided between the two spliced ​​flanges 1. By setting the insertion arc plate 5 and the insertion groove 4, the pipe is fixed to the positioning seat 3 of the flange 1 during installation. Then, the insertion arc plates 5 and the insertion groove 4 of the two flanges 1 are spliced ​​through the splicing slide 6 and the splicing slide 7. At the same time, the silicone sealing wing 8 is provided and abuts against the arc surface of the insertion groove 4 to seal, so that the connecting hole in the middle of the flange 1 is sealed by the insertion arc plate 5 and the insertion groove 4, which can achieve a good leak-proof effect and increase the sealing performance of the flange.

[0019] The thickness of the anti-leakage ring 11 is greater than twice the depth of the annular groove 10, and the inner diameter of the anti-leakage ring 11 is greater than the outer diameter of the plug-in arc plate 5.

[0020] The outer diameter of the insertion arc plate 5 is equal to the diameter of the insertion slot 4, and the length of the insertion arc plate 5 is the same as the depth of the insertion slot 4.

[0021] The cross-section of the splicing slide 7 is the same as that of the splicing slide 6. One end of the splicing slide 6 and the splicing slide 7 is flush with the bottom of the insertion groove 4, and the other end of the splicing slide 6 and the splicing slide 7 is flush with the end of the insertion arc plate 5.

[0022] A positioning block 12 is integrally provided on one side of the flange 1, located between the mounting holes 2, and a positioning hole 14 corresponding to the positioning block 12 is provided in the middle of the flange gasket 13.

[0023] The flange gasket 13 and the anti-leakage ring 11 are made of nitrile rubber. When the flange gasket 13 is squeezed and deformed during installation, it can completely fit with the outer circumferential surface of the sealing convex ring 9. By setting the flange gasket 13 and the anti-leakage ring 11, when the two flanges 1 are connected, the sealing convex rings 9 of the two flanges 1 are sealed again by the anti-leakage ring 11. At the same time, the flange gasket 13 is squeezed and deformed during installation, and it can completely fit with the outer circumferential surface of the sealing convex ring 9. This makes the plug-in arc plate 5 and the plug-in groove 4 form a triple seal with the flange gasket 13 and the anti-leakage ring 11 to prevent leakage, which greatly improves the sealing performance of the flange 1.

[0024] The insertion arc plate 5, insertion groove 4 and flange 1 are arranged at the same center, and the sealing wing 8 is made of silicone.

[0025] Working principle: During installation, the pipe is fixed to the positioning seat 3 of flange 1. Then, the insertion arc plates 5 and insertion grooves 4 of the two flanges 1 are spliced ​​together through the splicing slide 6 and splicing slide 7. At the same time, the silicone sealing wings 8 are tightly sealed with the arc surface of the insertion groove 4, so that the connecting hole in the middle of flange 1 is sealed by the insertion arc plates 5 and insertion grooves 4, which can achieve a good anti-leakage effect and increase the sealing performance of the flange. When the two flanges 1 are connected, the sealing convex rings 9 of the two flanges 1 are sealed again by the anti-leakage ring 11. At the same time, the flange gasket 13 is squeezed and deformed during installation, which can completely fit with the outer circumference of the sealing convex ring 9. This makes the insertion arc plates 5 and insertion grooves 4, flange gasket 13 and anti-leakage ring 11 form a triple seal to prevent leakage, greatly improving the sealing performance of flange 1.
