Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically a connection and sealing device for RTP pipelines. Background Technology

[0002] RTP (Reinforced Thermoplastic Pipe) is a high-performance pipe made of thermoplastic plastic and reinforcing materials, widely used in oil, natural gas, chemical, water treatment, and municipal engineering fields. It generally consists of an inner layer, a reinforcing layer, and an outer layer. During installation, connection and sealing devices are frequently used for RTP pipes.

[0003] Currently, Chinese patent CN220540512U discloses a pipe connection sealing structure, including a sealing ring. A first pipe body is disposed on the left side of the sealing ring, and a second pipe body is disposed on the right side of the sealing ring. A receiving ring is passed through and fixedly connected to the right side of the first pipe body, and a insertion groove is provided through the middle of the receiving ring. A sealing gasket is passed through and fixedly connected to the left side of the second pipe body, and a plug is passed through and fixedly connected to the middle of the left side of the sealing gasket. A connecting sleeve is passed through and fixedly connected to the right side of the outer diameter of the first pipe body. Locking rings are provided at both the upper and lower ends of the outer diameter of the sealing ring. In this utility model, the sealing ring, connecting sleeve, locking ring, mounting head, and gasket can seal the connection of the pipe bodies. The structure is simple and easy to operate, allowing for easy installation of two pipe bodies. After connection, the locking ring seals the sealing ring at the connection, improving the sealing performance of the connection and preventing interference with the normal use of the pipe bodies.

[0004] However, when the above-mentioned device is in use, it relies on bolts to press the locking ring, thereby enabling the internal sealing components to perform a sealing operation. However, as the usage time increases, the bolts will rust. At this time, the rust products (such as iron oxide) may fill the thread gaps. Initially, this may increase the friction, but under long-term repeated loads or vibrations, the rust layer will peel off, resulting in a reduction in the actual contact area between the threads, a significant decrease in friction, and the bolts will loosen more easily.

[0005] Therefore, this utility model provides a connection sealing device for RTP pipelines. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a connection sealing device for RTP pipelines to solve the above problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a connection and sealing device for RTP pipelines, comprising a first pipeline and a second pipeline, a sealing mechanism being provided between the first pipeline and the second pipeline, and a limit mechanism being provided outside the sealing mechanism;

[0008] The sealing mechanism includes a first connecting ring, which is connected to and fixed to a first pipe. A rotating groove is provided on one side of the first connecting ring. A second connecting ring is fixedly connected to one side of the second pipe and the two are connected. A rotating ring is provided on one side of the second connecting ring through a positioning element. The rotating ring is threadedly connected to the inner wall of the rotating groove.

[0009] Preferably, the positioning element includes a positioning ring with a T-shaped cross-section, and a positioning groove with a T-shaped cross-section is provided on one side of the second connecting ring, with the positioning ring and the inner wall of the positioning groove forming a sliding fit.

[0010] Preferably, a sealing ring is fixedly connected to one side of the second connecting ring. The sealing ring is made of rubber. A sealing groove is provided on one side of the first connecting ring, and the end of the sealing ring can be inserted into the sealing groove.

[0011] Preferably, the sealing ring in the sealing groove has a cavity, and the sealing ring in the sealing groove has a double-layer structure.

[0012] Preferably, the limiting mechanism includes a plurality of limiting rods, the outer wall of the first connecting ring is provided with a plurality of limiting grooves extending into the rotating groove, the outer wall of the rotating ring is provided with limiting openings corresponding to the limiting grooves one by one, and the limiting rods are threadedly connected to the inner walls of the limiting grooves and the inner walls of the limiting openings.

[0013] Preferably, a plurality of indicator blocks are fixedly connected to the outer wall of the rotating ring, and the indicator blocks correspond one-to-one with the limiting rods and are aligned.

[0014] Preferably, the indicator block is inclined on both sides near the first connecting ring, and the narrower part of the inclined surface of the indicator block faces the limiting rod.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) The connection sealing device for RTP pipelines is made by bringing the first connecting ring and the second connecting ring closer to each other and rotating the rotating ring so that the rotating ring rotates into the rotating groove. As the rotating ring rotates in the rotating groove, the distance between the first connecting ring and the second connecting ring becomes smaller. In subsequent use, since the first pipeline and the second pipeline are both heavy and far apart, a squeezing force can be formed between the rotating ring and the rotating groove, which can prevent the two from rotating and separating. Therefore, the connection can be prevented from being reduced in sealing performance due to loose threads, thus improving the sealing life.

[0018] (2) The connection sealing device for RTP pipeline can fix the rotating ring again by rotating the limiting rod into the inner wall of the limiting port and the inner wall of the limiting groove. Moreover, if the rotating ring is separated from the rotating groove due to external force, it can be pulled with the limiting rod, which can further ensure the limiting of the equipment. When installing the limiting rod, the installation operation can be carried out according to the position of the indicator block. That is, when the indicator block is aligned with the inner wall of the limiting groove, it means that the inner wall of the limiting groove is aligned with the inner wall of the limiting port.

[0024] 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.

[0025] Please see Figure 1-4A connection sealing device for RTP pipelines includes a first pipeline 1 and a second pipeline 2, a sealing mechanism is provided between the first pipeline 1 and the second pipeline 2, and a limit mechanism is provided outside the sealing mechanism.

[0026] The sealing mechanism includes a first connecting ring 3, which is connected to and fixed to the first pipe 1. A rotating groove 4 is provided on one side of the first connecting ring 3. A second connecting ring 5 is fixedly connected to one side of the second pipe 2 and the two are connected. A rotating ring 6 is provided on one side of the second connecting ring 5 through a positioning element. The rotating ring 6 is connected to the inner wall of the rotating groove 4 by a thread.

[0027] Specifically, by bringing the first connecting ring 3 and the second connecting ring 5 closer together, rotating the rotating ring 6 causes it to rotate into the rotating groove 4. As the rotating ring 6 rotates within the rotating groove 4, the distance between the first connecting ring 3 and the second connecting ring 5 becomes smaller. During subsequent use, since the first pipe 1 and the second pipe 2 are both heavy and far apart, a squeezing force is formed between the rotating ring and the rotating groove 4, preventing them from rotating apart. Therefore, the connection can be prevented from becoming loose due to thread loosening, thus improving the sealing life.

[0028] As a further improvement of this utility model, the positioning component includes a positioning ring 8, the positioning ring 8 having a T-shaped cross-section, and a positioning groove 7 having a T-shaped cross-section is provided on one side of the second connecting ring 5, with the positioning ring 8 and the inner wall of the positioning groove 7 forming a sliding fit.

[0029] Specifically, the positioning ring 8 can slide on the inner wall of the positioning groove 7, and the rotating ring 6 is in close contact with the second connecting ring 5, which can improve the sealing performance of the rotating ring 6.

[0030] As a further improvement of this utility model, a sealing ring 9 is fixedly connected to one side of the second connecting ring 5. The sealing ring 9 is made of rubber. A sealing groove 10 is opened on one side of the first connecting ring 3. The end of the sealing ring 9 can be inserted into the sealing groove 10. A cavity 11 is opened in the sealing ring 9 in the sealing groove 10. The sealing ring 9 located in the sealing groove 10 has a double-layer structure.

[0031] Specifically, the sealing ring 9 can slide into the sealing groove 10, and the rotating ring 6 can be rotated to make the sealing ring 9 more tightly squeezed in the sealing groove 10, and make the gap between the first connecting ring 3 and the second connecting ring 5 smaller.

[0032] As a further improvement of this utility model, the limiting mechanism includes a plurality of limiting rods 12, and the outer wall of the first connecting ring 3 is provided with a plurality of limiting grooves 13 extending into the rotating groove 4. The outer wall of the rotating ring 6 is provided with limiting openings 14 corresponding to the limiting grooves 13 one by one. The limiting rods 12 are connected to the inner walls of the limiting grooves 13 and the inner walls of the limiting openings 14 by threads.

[0033] Specifically, by rotating the limiting rod 12 into the inner wall of the limiting port 14 and the inner wall of the limiting groove 13, the rotating ring 6 can be fixed again. Moreover, if the rotating ring 6 is separated from the rotating groove 4 due to external force, it can be pulled with the limiting rod 12, which can further ensure the limiting of the equipment.

[0034] As a further improvement of this utility model, a number of indicator blocks 15 are fixedly connected to the outer wall of the rotating ring 6. The indicator blocks 15 correspond one-to-one with the limiting rods 12 and are aligned. The two sides of the indicator blocks 15 near the first connecting ring 3 are inclined, and the narrower part of the inclined surface of the indicator blocks 15 faces the limiting rods 12.

[0035] Specifically, the installation operation is carried out by setting the position of the indicator block 15. That is, when the indicator block 15 is aligned with the inner wall of the limiting groove 13, it means that the inner wall of the limiting groove 13 is aligned with the inner wall of the limiting port 14.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] The working principle of this utility model is as follows: In use, the first connecting ring 3 and the second connecting ring 5 are brought close to each other, and the rotating ring 6 is rotated so that the rotating ring 6 rotates into the rotating groove 4. At this time, the positioning ring 8 can slide on the inner wall of the positioning groove 7, and the rotating ring 6 is in close contact with the second connecting ring 5, which can improve the sealing performance of the rotating ring 6. As the rotating ring 6 rotates in the rotating groove 4, the sealing ring 9 can slide into the sealing groove 10. Continuing to rotate the rotating ring 6 can make the sealing ring 9 squeeze more tightly in the sealing groove 10, and make the gap between the first connecting ring 3 and the second connecting ring 5 smaller. In subsequent use, since the weight of the first pipe 1 and the second pipe 2 are relatively heavy and the distance is relatively long, the rotating ring and the rotating groove 4 can form a squeezing force, which can prevent the two from rotating and separating. Therefore, it can prevent the connection from being reduced in sealing performance due to loose threads, and achieve the effect of improving the sealing life.

[0038] After the rotating ring 6 is installed in the appropriate position, the limiting rod 12 is rotated into the inner wall of the limiting port 14 and the inner wall of the limiting groove 13, so that the rotating ring 6 can be fixed again. Moreover, if the rotating ring 6 is separated from the rotating groove 4 due to external force, it can be pulled with the limiting rod 12, which can further ensure the limiting of the equipment. When installing the limiting rod 12, the installation operation can be carried out according to the position of the indicator block 15. That is, when the indicator block 15 is aligned with the inner wall of the limiting groove 13, it means that the inner wall of the limiting groove 13 is aligned with the inner wall of the limiting port 14.
