Description
Technical Field
[0001] This utility model relates to the field of flange assembly technology, specifically a flange assembly with strong sealing performance and impact resistance. Background Technology
[0002] High-pressure and impact-resistant flange assemblies typically refer to high-pressure self-tightening flanges. These are pipeline connection assemblies used in harsh conditions such as high pressure, high temperature, and high corrosion. The core feature of this type of flange is its sealing method, which relies on the elastic deformation of the sealing lip of the sealing ring to form a hard seal. Compared with traditional soft seals, it has higher sealing reliability and strength. A search revealed a high-pressure and impact-resistant flange assembly disclosed in Chinese patent CN222209395U, comprising a pipeline, a high-pressure and impact-resistant flange, and a gasket. A bolt assembly is located on the outer side of the right end of the pipeline, and the outer side of the bolt assembly is fixedly connected by bolts. This high-pressure and impact-resistant flange features a rotating device rotatably connected to the outer side of a bolt assembly. A gasket is located inside the rotating device. The gasket includes a gasket body, with a fixing ring welded to the right end of the gasket body. A bolt is spirally connected to the inner side of the fixing ring, with a nut spirally connected to the right end of the bolt and a gear spirally connected to the left end of the bolt. A warning ring is fixedly connected to the outer side of the gasket body, and a sensor block is fixedly connected to the inner side of the warning ring. The rotating device includes a rotating ring, with a limit ring fixedly connected to the right side of the rotating ring. In this invention, the rotating device and gasket allow for rapid installation of the gasket by rotating the rotating device, thus improving work efficiency.
[0003] Currently, in the process of connecting existing flange assemblies, the materials and bolts are usually interlocked and fixed, and the bolts are distributed in a ring at equal intervals on the outside of the flange. Therefore, it is necessary to ensure that each set of bolts is precisely aligned in order to complete the connection. This structure results in low assembly efficiency of the flange. Utility Model Content
[0004] To address the problem that existing flange assemblies are not convenient for quick assembly, this invention provides a flange assembly with strong sealing performance and impact resistance.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A high-sealing, impact-resistant flange assembly includes a first pipe and a second pipe. A flange structure is provided between the first pipe and the second pipe. The flange structure includes a first ring and a second ring. The outer wall of the first ring is provided with a first right-angle locking block, and the outer wall of the second ring is provided with a second right-angle locking block that engages with the first right-angle locking block. The first right-angle locking block and the second right-angle locking block are arranged in a cross shape on the outer wall of the flange structure. An insertion component connects the first right-angle locking block and the second right-angle locking block.
[0006] Furthermore, a second ring is fitted onto one end of the first pipe, and a first ring is fitted onto one end of the second pipe.
[0007] The beneficial effect of adopting the above-mentioned further solution is that the connection method of the first pipe fitting the second ring and the second pipe fitting the first ring makes the flange structure and the pipe form a tight nested fit, which increases the contact area between the two and improves the stability of the connection.
[0008] Furthermore, annular grooves are respectively formed on adjacent sides of the first and second ring members, and concave and convex rings that fit each other are respectively embedded in the interior of the two annular grooves.
[0009] The beneficial effects of adopting the above-mentioned further solution are that the annular groove provides precise installation space for the concave ring and the convex ring, ensuring accurate positioning after they are embedded; the structure of the concave ring and the convex ring matching each other forms a ring-shaped sealing barrier, which extends the leakage path of the medium and effectively blocks the penetration of liquid or gas media.
[0010] Furthermore, a sealing assembly is provided at the connection between the concave ring and the convex ring.
[0011] The beneficial effects of adopting the above-mentioned further solution are that the sealing component can fill the tiny gaps in the mating surfaces of the concave and convex rings, avoiding sealing failure caused by machining accuracy or assembly errors. At the same time, the sealing component has a certain degree of elasticity, which can absorb the stress caused by pipeline vibration and temperature changes, prevent the sealing structure from being damaged by rigid impact, and improve the long-term stability of the seal.
[0012] Furthermore, the sealing assembly includes an outer rubber ring, a thickened rubber ring, and an inner rubber ring, wherein the outer rubber ring, the thickened rubber ring, and the inner rubber ring are located on the same axis, and the outer rubber ring and the inner rubber ring are located on the same vertical plane.
[0013] The beneficial effects of adopting the above-mentioned further solution are that the outer rubber ring, the thickened rubber ring, and the inner rubber ring are set coaxially to ensure that the sealing pressure is evenly distributed on the mating surface of the concave and convex rings, avoiding local sealing failure; the design of the outer rubber ring and the inner rubber ring being on the same vertical plane makes the sealing surface form a complete annular sealing band, optimizing the sealing effect.
[0014] Furthermore, the insertion assembly includes a shaft, one end of which is provided with a stud, and one end of the stud is threadedly connected with an anti-disengagement cap, which is embedded and installed on one side of the first right-angle block.
[0015] The beneficial effects of adopting the above-mentioned further solution are that the shaft passes through and connects the first right-angle clamp and the second right-angle clamp, realizing the rigid fixation of the two clamps, enhancing the overall connection strength of the flange structure, and improving the impact resistance; the threaded connection between the bolt and the anti-dislodgement cap is firm and reliable, which can effectively prevent the shaft from loosening or falling off, and ensure the long-term stability of the fixing effect; the anti-dislodgement cap is embedded and installed on one side of the first right-angle clamp, avoiding the impact damage caused by the protruding structure, while keeping the outer wall of the flange assembly flat.
[0016] Furthermore, one end of the shaft extends to the outside of the second right-angle block and is provided with a twist cap.
[0017] The advantage of adopting the above-mentioned further solution is that the torsion cap provides the operator with a convenient point of force application, and the tightness of the shaft can be adjusted by rotating the torsion cap.
[0018] Compared with the prior art, the beneficial effects of this utility model are: This type of high-sealing, impact-resistant flange assembly, through the combined use of the flange structure and the insertion component, enables quick assembly while providing sealing and impact resistance. The first and second pipes are securely connected via the flange structure. The first and second rings of the flange structure are positioned to correspond to the pipes, ensuring compatibility. Furthermore, the first and second right-angle locking blocks on the outside of the two sets of rings engage with each other, allowing for precise alignment between the first and second rings during relative rotation. The cross-shaped locking block design ensures even stress distribution on the flange structure, dispersing the impact force generated during pipeline transport and improving overall impact resistance. The insertion component connects the two right-angle locking blocks, providing a secure fixation effect and preventing the flange structure from loosening under impact or vibration.

[0021] 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.
[0022] Please see Figures 1-5 This utility model provides a technical solution: a high-sealing and impact-resistant flange assembly, including a first pipe 1 and a second pipe 2, with a flange structure 3 between the first pipe 1 and the second pipe 2. The flange structure 3 includes a first ring 301 and a second ring 302. The first pipe 1 and the second pipe 2 are stably connected through the flange structure 3. The first ring 301 and the second ring 302 of the flange structure are arranged corresponding to the pipes to ensure connection compatibility. The outer wall of the first ring 301 is provided with a first right-angle locking block 303, and the outer wall of the second ring 302 is provided with a second right-angle locking block 304 that engages with the first right-angle locking block 303. The first rings on the outside of the two sets of rings are... Right-angle locking block 303 and second right-angle locking block 304 engage with each other, allowing for precise alignment between the first ring 301 and the second ring 302 while rotating relative to each other. The first right-angle locking block 303 and second right-angle locking block 304 are arranged in a cross shape on the outer wall of the flange structure 3. This cross-shaped design ensures uniform stress on the flange structure, dispersing the impact force generated during pipeline transportation and improving overall impact resistance. An insertion component 4 connects the first right-angle locking block 303 and second right-angle locking block 304, enabling the two sets of locking blocks to achieve a fixing effect, thereby preventing the flange structure from loosening under impact or vibration.
[0023] As an embodiment of this utility model, the second ring 302 is fitted onto one end of the first pipe 1 and the first ring 301 is fitted onto one end of the second pipe 2. The connection method of the first pipe 1 fitted with the second ring 302 and the second pipe 2 fitted with the first ring 301 makes the flange structure 3 and the pipe form a tight nested fit, which increases the contact area between the two and improves the stability of the connection.
[0024] As an embodiment of this utility model, further, annular grooves 7 are respectively provided on the adjacent sides of the first ring member 301 and the second ring member 302. The two annular grooves 7 are respectively fitted with a concave ring 5 and a convex ring 6 that fit together. The annular grooves 7 provide a precise installation space for the concave ring 5 and the convex ring 6, ensuring accurate positioning after they are fitted. The structure of the concave ring 5 and the convex ring 6 that fit together forms a ring-shaped sealing barrier, extending the leakage path of the medium and effectively blocking the penetration of liquid or gas medium. A sealing component 8 is provided at the connection between the concave ring 5 and the convex ring 6. The sealing component 8 can fill the tiny gaps between the mating surfaces of the concave and convex rings, avoiding sealing failure caused by machining accuracy or assembly errors. At the same time, the sealing component 8 has a certain elasticity, which can absorb the stress caused by pipeline vibration and temperature changes, prevent the sealing structure from being damaged by rigid impact, and improve the long-term stability of the seal.
[0025] As one embodiment of this utility model, the sealing component 8 further includes an outer rubber ring 801, a thickened rubber ring 802, and an inner rubber ring 803. The outer rubber ring 801, the thickened rubber ring 802, and the inner rubber ring 803 are located on the same axis. The outer rubber ring 801 and the inner rubber ring 803 are located on the same vertical plane. The coaxial arrangement of the outer rubber ring 801, the thickened rubber ring 802, and the inner rubber ring 803 ensures that the sealing pressure is evenly distributed on the mating surface of the concave and convex rings, avoiding local sealing failure. The design that the outer rubber ring 801 and the inner rubber ring 803 are located on the same vertical plane makes the sealing surface form a complete annular sealing band, optimizing the sealing effect.
[0026] As an embodiment of this utility model, the insertion assembly 4 further includes a shaft 401, one end of which is provided with a stud 402. One end of the stud 402 is threadedly connected to an anti-detachment cap 403. The anti-detachment cap 403 is embedded in one side of the first right-angle locking block 303. The shaft 401 passes through and connects the first right-angle locking block 303 and the second right-angle locking block 304, thereby achieving rigid fixation of the two blocks, enhancing the overall connection strength of the flange structure 3, and improving impact resistance. The threaded connection between the stud 402 and the anti-detachment cap 403 is firm and reliable, effectively preventing the shaft from loosening or falling off, and ensuring long-term stability of the fixing effect. The anti-detachment cap is embedded in one side of the first right-angle locking block to avoid bump damage caused by the protruding structure, while keeping the outer wall of the flange assembly flat. One end of the shaft 401 extends to the outside of the second right-angle locking block 304 and is provided with a torsion cap 404. The torsion cap 404 provides a convenient force application point for the operator, and the tightness of the shaft 401 can be adjusted by rotating the torsion cap 404.
[0027] Specifically, the working principle of this type of high-sealing and impact-resistant flange assembly is as follows: In use, the second ring 302 of the flange structure 3 is first fitted onto one end of the first pipe 1, and the first ring 301 of the flange structure is fitted onto one end of the second pipe 2. This nesting fit achieves initial fixation between the pipe and the flange. Then, the two rings are rotated so that the first right-angle locking block 303 on the outer wall of the first ring 301 and the second right-angle locking block 304 on the outer wall of the second ring 302 engage with each other. The cross-shaped distribution of the locking blocks completes the precise connection of the two rings and distributes the force. After connection, the concave ring 5 and convex ring 6 within the annular groove 7 on the adjacent sides of the first and second rings... The natural fit forms the first line of sealing defense. The sealing components 8 (outer rubber ring 801, thickened rubber ring 802, and inner rubber ring 803) at the connection fill the gaps in the mating surfaces, forming a complete annular sealing band through the coaxial triple rubber rings. Finally, the shaft 401 of the insert component 4 is connected through two right-angle blocks, so that the bolt 402 at one end of the shaft is threadedly fixed to the anti-dislodgement cap 403 on the side of the first right-angle block. The tightness is adjusted by the torsion cap 404 on the outside of the second right-angle block to achieve rigid fixation of the flange structure. The entire process of "precise docking - multiple sealing - stable fixation" ensures the impact resistance and sealing of the pipeline connection.
