Description

Technical Field

[0001] This utility model relates to the field of pipe fittings, and in particular to a sealing ring for leak-proof sealing of pipe connections using ring compression and ring clamping. Background Technology

[0002] Pipelines in a piping system need to be connected to each other using pipe fittings. For example, patent application number CN202220372048.5 discloses a new type of pipe fitting that connects two pipes via an inlet connector and an outlet connector. The connection method between the inlet and outlet connectors and the pipes is mainly threaded. However, this pipe fitting has the following drawbacks during use: 1) The threaded connection is susceptible to external vibration or corrosion, which may lead to seal failure; 2) During installation, it is necessary to ensure that the threads are secure. The thread machining precision is poor; too loose and leakage is likely, while too tight may damage the pipe fitting or the plastic lining. Disassembly during maintenance is complicated and may damage the thread structure, making installation and maintenance very inconvenient and inefficient. 3) Long-term operation may lead to thread wear and corrosion, increasing the probability of leakage. 4) The applicable scenarios are limited, mainly suitable for connecting pipe fittings with smaller diameters, and not suitable for connecting large-diameter pipe fittings. 5) The sealing ring of this connector is mainly set in the inlet or outlet joint, specifically in the groove of its inner stepped surface. Although the sealing ring can play a certain sealing role, the sealing effect is not enough. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model aims to provide a leak-proof sealing ring for ring-clamped pipe connections, solving the problems of existing technologies. The ring-clamped double-seal pipe fitting not only facilitates installation and maintenance, improving efficiency, but also significantly enhances connection stability and sealing performance, while improving compatibility. By setting a leak-proof sealing ring at the end of the ring-clamped double-seal pipe fitting, this utility model pre-fixes the sealing ring to the fitting, facilitating on-site installation and improving efficiency. Furthermore, it further enhances the sealing performance between the fitting and the pipe itself, while also providing excellent protection for the fitting.

[0004] (II) Technical Solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing ring for ring-clamped pipe connections to prevent leakage, comprising a ring-clamped double-seal pipe fitting, wherein a leakage-free sealing ring is fixed to the right end of the ring-clamped double-seal pipe fitting.

[0006] Preferably, the leak-proof sealing ring includes a first annular sealing portion, a second annular sealing portion integrally formed therewith on the outer wall surface of the first annular sealing portion, the right end face of the second annular sealing portion being flush with the right end face of the first annular sealing portion, and its left end face extending beyond the left end face of the first annular sealing portion, and a third annular sealing portion integrally formed therewith on the inner wall surface of the first annular sealing portion, the right end face of the third annular sealing portion being flush with the right end face of the first annular sealing portion, and its left end face extending beyond the left end face of the second annular sealing portion, and a groove is formed between the first annular sealing portion, the second annular sealing portion and the third annular sealing portion.

[0007] Preferably, the ring-clamp double-sealed pipe fitting includes a connecting ring, with symmetrical ring-clamp joints connected to the left and right ends of the connecting ring. The ring-clamp joint includes a first connecting part fixed to the connecting ring, a first annular part fixed to the first connecting part, an arc-shaped protrusion fixed to the first annular part, a second annular part fixed to the arc-shaped protrusion, a second connecting part fixed to the second annular part, and a third annular part fixed to the second connecting part.

[0008] Preferably, the outer diameter of the first connecting portion near the connecting ring is smaller than the outer diameter of the end away from the connecting ring, and the outer diameter of the second connecting portion near the connecting ring is smaller than the outer diameter of the end away from the connecting ring.

[0009] Preferably, the arc-shaped protrusion includes an arc-shaped protrusion body, and a sealing part is fixed inside the arc-shaped protrusion body, the inner wall surface of the sealing part extending beyond the inner wall surface of the first annular part.

[0010] Preferably, the left end of the ring-clamp double-seal pipe fitting is also fixed with a leak-proof sealing ring.

[0011] Preferably, the right end face of the first annular sealing part is fixed with an arc-shaped block protruding to the right, and the arc-shaped block is integrally formed with the first annular sealing part.

[0012] Preferably, the inner wall surface of the third annular sealing part is provided with several arc-shaped grooves.

[0013] Preferably, a first adhesive layer is fixed on the inner wall surface of the second annular sealing part, and a second adhesive layer is fixed on the outer wall surface of the third annular sealing part.

[0014] (III) Beneficial Effects

[0015] 1. This utility model relates to a leak-proof sealing ring for ring-press and ring-clamp pipe connections. During installation and maintenance, it eliminates the cumbersome step of first attaching the ring-type sealing ring to the pipe and then connecting it to the fittings. Through its design with a ring-press and ring-clamp dual-seal connection body, this leak-proof sealing ring for ring-press and ring-clamp pipe connections can be directly connected to the pipe without the additional step of attaching the ring-type sealing ring, thus greatly improving the efficiency of installation and maintenance.

[0016] 2. This utility model is used for sealing rings in ring-pressed and ring-clamped pipe connections to prevent leaks. During installation and maintenance, the second annular sealing part will fall off after crimping, exposing the ring-clamped double-sealed pipe fitting. This clearly shows whether the ring-clamped double-sealed pipe fitting was missed or forgotten during installation and maintenance. This not only improves installation efficiency but also ensures the sealing of the pipe connection and enhances the reliability of the product for installation and construction.

[0017] 3. Compared to threaded connections, this utility model, through the design of the ring-clamp double-seal pipe fitting, not only greatly improves the efficiency of installation and maintenance, but also significantly enhances the stability and sealing of the connection, while also improving adaptability, making it suitable for both small and large diameter pipe fittings. The inclusion of a leak-proof sealing ring pre-fixes the ring-clamp double-seal pipe fitting, facilitating on-site installation and improving efficiency. Furthermore, it further enhances the sealing performance between the ring-clamp double-seal pipe fitting and the pipe fitting itself, while also providing excellent protection for the fitting.

[0018] 4. This utility model, by setting the leak-free sealing ring to consist of a first annular sealing part, a second annular sealing part, and a third annular sealing part, encloses the double-sealed pipe fitting. On the one hand, it increases the fixing firmness between the pipe fitting and the double-sealed pipe fitting; on the other hand, it provides a double-layer seal for the leakage of liquid inside the pipe fitting, greatly improving the sealing performance and preventing liquid leakage. At the same time, the setting of the leak-free sealing ring in this structure effectively prevents the leak-free sealing ring from shifting during the insertion of the pipe fitting into the double-sealed pipe fitting. In addition, the leak-free sealing ring also provides good protection for the right end of the double-sealed pipe fitting, preventing damage caused by bumps during transportation or handling, and preventing the relatively sharp end of the double-sealed pipe fitting from scratching the operator, thus eliminating safety hazards.

[0019] 5. This utility model sets the ring-clamp double-sealed pipe fitting to consist of a connecting ring and two symmetrical ring-clamp joints. The left end of the ring-clamp double-sealed pipe fitting is also fixed with a leak-proof sealing ring. This allows two separate pipe fittings to be connected. When connecting, simply insert the two pipe fittings into the two ring-clamp joints respectively, which is very convenient.

[0020] 6. This utility model, by configuring the ring clamp joint part as a first connecting part, a first annular part, an arc-shaped protrusion, a second annular part, a second connecting part, and a third annular part, gives the ring clamp joint part a certain height difference, thereby further improving the fixing firmness and sealing between the ring clamp joint part and the pipe fitting.

[0021] 7. This utility model improves sealing performance by using an arc-shaped protrusion and a sealing part, where the sealing part fills the entire arc-shaped protrusion body. This not only increases the thickness but also the width of the sealing part. In addition, the arc-shaped protrusion of the sealing part can further improve the sealing performance and prevent leakage compared to a flat shape. Furthermore, by pre-installing and fixing the sealing part into the arc-shaped protrusion body, it is not necessary to install the sealing part first during on-site installation, which facilitates the installation of pipe fittings and improves installation efficiency.

[0022] 8. By setting the arc-shaped block, this utility model greatly increases the thickness of the first annular sealing part, which effectively prevents the first annular sealing part from being broken by the port of the ring clamp joint during the pulling process, and increases the service life of the leak-proof sealing ring.

[0023] 9. By setting the arc-shaped groove, this utility model increases the friction between the leak-proof sealing ring and the pipe fitting. On the other hand, the arc-shaped groove will form a negative pressure state after being squeezed, which firmly adsorbs the wall surface of the pipe fitting, greatly improving the fixing firmness and sealing performance between the leak-proof sealing ring and the pipe fitting.

[0024] 10. By setting the first adhesive layer and the second adhesive layer, this utility model greatly facilitates the fixing of the leak-proof sealing ring and the ring-clamp double-sealed pipe fitting. The inner wall surface of the first annular sealing part and the end face of the ring-clamp double-sealed pipe fitting are not bonded together by the adhesive layer, thus ensuring a certain degree of mobility of the first annular sealing part and leaving sufficient slack for it to be pulled inward during the insertion of the pipe fitting.

Detailed Implementation

[0033] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] This utility model provides a technical solution: a leak-proof sealing ring for ring-clamped pipe connections, comprising a ring-clamped double-seal pipe fitting 1, with a leak-proof sealing ring 2 fixed to the right end of the ring-clamped double-seal pipe fitting 1. When connecting the pipe fitting to the ring-clamped double-seal pipe fitting 1, simply insert the pipe fitting into the right end of the ring-clamped double-seal pipe fitting 1. When maintenance is required, simply pull the pipe fitting out of the ring-clamped double-seal pipe fitting 1. This is very convenient. Compared with the threaded connection in the prior art, it not only greatly improves the efficiency of installation and maintenance, but also greatly improves the stability and sealing of the connection, while also improving adaptability, applicable to both small-diameter and large-diameter pipe fittings. The leak-proof sealing ring 2 is pre-fixed to the end of the ring-clamp double-seal pipe fitting. This pre-fixes the sealing ring 2 to the ring-clamp double-seal pipe fitting 1, facilitating on-site installation and improving efficiency. It also further enhances the seal between the ring-clamp double-seal pipe fitting 1 and the pipe fitting, while providing excellent protection for the fitting. The ring-clamp double-seal pipe fitting 1 and the pipe fitting are pre-matched; the size and shape of the fitting are determined based on the required dimensions and shape of the connecting pipe fitting.

[0035] The leak-proof sealing ring 2 includes a first annular sealing part 3. A second annular sealing part 4 is integrally formed on the outer wall of the first annular sealing part 3. The right end face of the second annular sealing part 4 is flush with the right end face of the first annular sealing part 3, and its left end face extends beyond the left end face of the first annular sealing part 3. A third annular sealing part 5 is integrally formed on the inner wall of the first annular sealing part 3. The right end face of the third annular sealing part 5 is flush with the right end face of the first annular sealing part 3, and its left end face extends beyond the left end face of the second annular sealing part 4. A groove 6 is formed between the first annular sealing part 3, the second annular sealing part 4, and the third annular sealing part 5. The right end of the ring-clamping double-sealing pipe fitting 1 fits perfectly into the groove 6 and is fixed to the leak-proof sealing ring 2. The leak-proof sealing ring 2 in this structure wraps around the double-seal pipe fitting 1, increasing the fixation between them and the fitting. It also provides a double seal at the point where liquid leaks out, significantly improving sealing and preventing leakage. Furthermore, the leak-proof sealing ring 2 effectively prevents displacement during insertion of the fitting into the double-seal pipe fitting 1. Additionally, it protects the right end of the fitting, preventing damage during transport or handling, and preventing cuts from the relatively sharp end, thus eliminating safety hazards.

[0036] The ring-clamp double-seal pipe fitting 1 includes a connecting ring 7, with symmetrical ring-clamp connectors 8 connected to both ends of the connecting ring 7. Each ring-clamp connector 8 includes a first connecting portion 9 fixed to the connecting ring 7, a first annular portion 10 fixed to the first connecting portion 9, an arc-shaped protrusion 11 fixed to the first annular portion 10, a second annular portion 12 fixed to the arc-shaped protrusion 11, a second connecting portion 13 fixed to the second annular portion 12, and a third annular portion 14 fixed to the second connecting portion 13. The ring-clamp double-seal pipe fitting 1 is configured to consist of the connecting ring 7 and two symmetrical ring-clamp connectors 8, allowing two separate pipe fittings to be connected. During connection, the two pipe fittings are simply inserted into the two ring-clamp connectors 8 respectively. A leak-proof sealing ring 2 is also fixed to the left end of the ring-clamp double-seal pipe fitting 1. The ring-clamp joint 8 is configured to consist of a first connecting part 9, a first annular part 10, an arc-shaped protrusion 11, a second annular part 12, a second connecting part 13, and a third annular part 14, so that the ring-clamp joint 8 has a certain height hierarchy, thereby further improving the fixing firmness and sealing between the ring-clamp joint 8 and the pipe fitting.

[0037] The outer diameter of the first connecting part 9 near the connecting ring 7 is smaller than the outer diameter of the end away from the connecting ring 7, and the outer diameter of the second connecting part 13 near the connecting ring 7 is smaller than the outer diameter of the end away from the connecting ring 7. This arrangement makes the outer end of the ring clamp joint 8 larger than the inner end, facilitating the insertion of the pipe fitting. Furthermore, it creates a layered contact between the ring clamp joint 8 and the pipe fitting, thereby improving the sealing and secure fixing between the ring clamp joint 8 and the outer pipe fitting.

[0038] The arc-shaped protrusion 11 includes an arc-shaped protrusion body 15, within which a sealing portion 16 is fixed. The inner wall surface of the sealing portion 16 extends beyond the inner wall surface of the first annular portion 10. The sealing portion 16 fills the entire arc-shaped protrusion body 15, thus increasing both its thickness and width, thereby improving sealing performance. Furthermore, the arc-shaped protrusion of the sealing portion 16 further enhances sealing performance compared to a flat shape, preventing leakage. Since the inner wall surface of the sealing portion 16 extends beyond the inner wall surface of the arc-shaped protrusion body 15, it exerts a squeezing effect on the sealing portion 16 during pipe insertion into the ring-clamp joint portion 8, achieving a sealing effect. By pre-installing and fixing the sealing portion 16 within the arc-shaped protrusion body 15, it is not necessary to install the sealing portion 16 first during on-site installation, facilitating pipe installation and improving installation efficiency.

[0039] An arc-shaped block 17 protruding to the right is fixed to the right end face of the first annular sealing part 3, and the arc-shaped block 17 is integrally formed with the first annular sealing part 3. During the process of inserting the pipe fitting into the ring clamp joint part 8, the third annular sealing part 5 will inevitably be pulled inward to a certain extent, which in turn will pull the first annular sealing part 3 inward. The first annular sealing part 3 corresponds to the port of the ring clamp joint part 8. The first annular sealing part 3 becomes thinner during the pulling process and is easily broken by the port of the ring clamp joint part 8, or it is easy to break during subsequent use. Therefore, by setting the arc-shaped block 17, the thickness of the first annular sealing part 3 is greatly increased, which effectively prevents the first annular sealing part 3 from being broken by the port of the ring clamp joint part 8 during the pulling process, and increases the service life of the leak-proof sealing ring 2.

[0040] The inner wall of the third annular sealing part 5 is provided with several arc-shaped grooves 18. By setting the arc-shaped grooves 18, on the one hand, the friction between the leak-proof sealing ring 2 and the pipe is increased, and on the other hand, the arc-shaped grooves 18 will form a negative pressure state after being squeezed, firmly adhering to the wall of the pipe, which greatly improves the fixing firmness and sealing performance between the leak-proof sealing ring 2 and the pipe.

[0041] The first adhesive layer 19 is fixed on the inner wall surface of the second annular sealing part 4, and the second adhesive layer 20 is fixed on the outer wall surface of the third annular sealing part 5. This is one way to fix the leak-free sealing ring 2 and the ring-clamp double-seal pipe fitting 1. A release paper is fixed to both the first adhesive layer 19 and the second adhesive layer 20. When fixing the two, first, insert the right end of the ring-clamp double-seal pipe fitting 1 into the groove 6 of the leak-free sealing ring 2. Since the leak-free sealing ring 2 has a certain elasticity, then slightly lift the second annular sealing part 4 upwards, then peel off the release paper on the first adhesive layer 19, and then stick the first adhesive layer 19 to the outer wall surface of the end of the ring-clamp double-seal pipe fitting 1. Similarly, stick the second adhesive layer 20 to the inner wall surface of the end of the ring-clamp double-seal pipe fitting 1. This method greatly facilitates the fixing of the leak-free sealing ring 2 and the ring-clamp double-seal pipe fitting 1. The inner wall surface of the first annular sealing part 3 and the end face of the ring-clamp double-seal pipe fitting 1 are not bonded together by the adhesive layer, thus ensuring a certain degree of mobility for the first annular sealing part 3, providing sufficient slack for inward pulling during pipe insertion. This is just one way to fix the leak-proof sealing ring 2 and the ring-clamp double-sealed pipe fitting 1. Alternatively, they can be fixed by means of hot melt adhesive.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
