Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe technology, and in particular to durable connecting components for corrosion-resistant fiberglass pipes. Background Technology

[0002] Fiberglass pipe, also known as glass fiber reinforced plastic pipe, is a type of pipe made of glass fiber reinforcement and resin matrix. It has high resistance to most chemicals and corrosive media, making it suitable for corrosive environments. It can also withstand high temperatures, making it suitable for high-temperature media transmission. Although its density is much lower than that of metal pipes, it has high strength and rigidity. At the same time, the surface of fiberglass pipe is smooth, the coefficient of friction is low, and it is an electrical insulator, making it suitable for power system applications. Its production methods include pultrusion, which uses a continuous pultrusion process to form pipes from glass fiber and resin matrix; winding, which involves winding glass fiber yarn and cloth onto a mandrel and coating it with resin to form pipes; and molding, which involves placing glass fiber and resin matrix in a mold, heating and pressurizing to form pipes. Because fiberglass pipes are mostly used to transport chemical materials, their joints are easily corroded.

[0003] If adhesive is used in the connection components of FRP pipes, it will age and lose its stickiness over time, causing the connection to loosen and corrode. Furthermore, the medium transported in the pipeline may be corrosive. Current technologies often employ coating the surface of the connection components with anti-corrosion coatings and selecting connection components compatible with the FRP pipe material to avoid electrochemical corrosion. However, after long-term use, wear and corrosion will still occur due to aging. In this case, the entire connection component needs to be replaced to prevent fluid leakage from the pipeline, leading to increased maintenance costs and a shortened service life. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a corrosion-resistant and durable connecting component for fiberglass pipes. It aims to improve the existing fiberglass pipe connecting components, which suffer wear and corrosion due to aging after long-term use, requiring the replacement of the entire connecting component. This avoids fluid leakage in the pipeline, which leads to increased maintenance costs and shortened service life.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a durable connecting component for corrosion-resistant fiberglass pipes, including a connecting ring, a plurality of rotating rods rotatably connected to the inner wall of the connecting ring, a connecting sleeve slidably connected to the inner wall of the connecting ring, a positioning block fixedly connected to one adjacent end of the plurality of rotating rods, a limit block fixedly connected to one opposite end of the plurality of rotating rods, a limit plate second provided on the outer wall of the limit block, a plurality of limit screws connected to the inner wall of the limit plate second, a limit groove opened in the middle of the inner wall of the limit screws, a plurality of positioning guide grooves opened on the outer wall of the connecting sleeve, a rotating groove opened in the middle of the inner wall of the positioning guide grooves, and a plurality of adjustment mechanisms provided on the top of the connecting ring, the adjustment mechanisms being used to adapt to pipes of different heights for connection.

[0006] As a further description of the above technical solution:

[0007] The adjustment mechanism includes a T-shaped guide groove, which is disposed on the top of the connecting ring. A T-shaped plate is slidably connected to the inner wall of the T-shaped guide groove. An installation ring is fixedly connected to an adjacent side of a plurality of T-shaped plates. A bolt is slidably connected to the inner wall of the T-shaped plate. A plurality of nuts are provided on the outer wall of the bolt. A plurality of limiting plates are fixedly connected to the outer wall of the installation ring. An installation screw is threadedly connected to the inner wall of the limiting plate.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the mounting screw is provided with a washer two, and the inner wall of the washer two is slidably connected to the outer wall of the mounting screw.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the nut is provided with a washer, and the outer wall of the washer fits against the outer wall of the nut.

[0012] As a further description of the above technical solution:

[0013] A rubber pad is fixedly connected to the inner wall of the mounting ring, and the multiple T-shaped plates are slidably connected at the same horizontal height.

[0014] As a further description of the above technical solution:

[0015] A connecting pipe 1 is slidably connected to the inner wall of the mounting ring near its edge, and a connecting pipe 2 is slidably connected to the bottom of the inner wall of the mounting ring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by unscrewing the limiting screw, the second limiting plate is removed from the outer wall of the connecting ring, thereby disengaging the limiting groove from the outer wall of the limiting block. Then, the limiting block is rotated to drive the rotating rod to rotate, which in turn drives the positioning block to rotate, allowing it to rotate within the rotating groove until it is level with the positioning guide groove. Then, the connecting sleeve is pulled upward to remove it along the positioning guide groove for replacement, achieving the replacement of a single corrosion-resistant component, reducing maintenance costs, and extending service life.

[0022] 2. In this utility model, pipes with height differences are inserted into the mounting rings on both sides, allowing them to push the mounting rings and thus drive the T-shaped plate to slide within the T-shaped guide groove. After adjusting to the appropriate position, the nuts at both ends of the bolts are tightened to limit the position of the pipes within the T-shaped plate. Then, the mounting screws are screwed into the limiting plate to fix the limiting plate and the outer wall of the connecting ring. This achieves the purpose of adapting to the installation of pipes with height differences, improving practicality and enhancing the stability after installation. Attached Figure Description

[0030] 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.

[0031] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a corrosion-resistant fiberglass pipe durable connecting component, including a connecting ring 1. Multiple rotating rods 4 are rotatably connected to the inner wall of the connecting ring 1. The connecting ring 1 is used for close-fitting connection with multiple pipes. A connecting sleeve 11 is slidably connected to the inner wall of the connecting ring 1. Positioning blocks 3 are fixedly connected to adjacent ends of the multiple rotating rods 4. The connecting sleeves 11 are used to seal the connection and resist corrosion. Limiting blocks 5 are fixedly connected to the ends of the multiple rotating rods 4 that are furthest apart. Limiting plates 8 are provided on the outer wall of the limiting blocks 5. Position plate 2 8 is used to limit the position of limit block 5. Multiple limit screws 7 are connected to the inner wall of limit plate 2 8. Limit groove 6 is opened in the middle of the inner wall of limit screw 7. Multiple positioning guide grooves 9 are opened on the outer wall of connecting sleeve 11. Limit screw 7 is used to limit the position of limit plate 2 8. Rotation groove 10 is opened in the middle of the inner wall of positioning guide groove 9. Multiple adjustment mechanisms 2 are provided on the top of connecting ring 1. Adjustment mechanism 2 is used to adapt to the connection of pipes with different heights. Rotation groove 10 is used to engage with positioning block 3.

[0032] Specifically, the main function of the connecting ring 1 is to fit and connect with multiple fiberglass pipes, with a large contact area to improve the reliability of the connection. The connecting sleeve 11 can not only seal the connection of the fiberglass pipes to prevent media leakage, but also effectively resist the erosion of various corrosive media and extend the service life of the connecting parts. The shape of the positioning block 3 matches the rotating groove 10 on the outer wall of the connecting sleeve 11, which can achieve locking and ensure the stable position of the connecting sleeve 11 during the working process. The position of the limiting plate 2 8 limiting block 5 is limited to prevent the rotating rod 4 from rotating excessively, thereby ensuring the normal operation of the connecting parts. The function of the positioning guide groove 9 is to provide guidance for the installation of the positioning block 3.

[0033] Please see the appendix Figure 3 - Appendix Figure 5 The adjusting mechanism 2 includes a T-shaped guide groove 204, which is located on the top of the connecting ring 1. A T-shaped plate 202 is slidably connected to the inner wall of the T-shaped guide groove 204. An installation ring 201 is fixedly connected to the adjacent side of multiple T-shaped plates 202. The T-shaped guide groove 204 is used to guide the T-shaped plates 202 to slide within it. A bolt 203 is slidably connected to the inner wall of the T-shaped plate 202. Multiple nuts 207 are provided on the outer wall of the bolt 203. Multiple limiting plates 206 are fixedly connected to the outer wall of the installation ring 201. The bolt 203 is used to limit the position of the T-shaped plate 202. An installation screw 205 is threadedly connected to the inner wall of the limiting plate 206. The installation screw 205 is used to install the limiting plate 206.

[0034] Specifically, the T-shaped guide groove 204 can effectively guide the T-shaped plate 202 to slide, and can also prevent the T-shaped plate 202 from tipping over or shifting during the sliding process through the limiting walls on both sides of the groove, ensuring the stability and reliability of the adjustment process, pushing the T-shaped plate 202 to slide in the T-shaped guide groove 204, thereby adjusting the height of the installation ring 201 according to actual needs, ensuring that the connection of the pipe installation will not bend, and the nut 207 can adjust its position by rotating the outer wall of the bolt 203, thereby limiting the position of the T-shaped plate 202.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 The outer wall of the mounting screw 205 is provided with a washer 16, and the inner wall of the washer 16 is slidably connected to the outer wall of the mounting screw 205. The washer 16 is used to increase the contact area between the mounting screw 205 and its bottom. The inner wall of the mounting ring 201 is fixedly connected with a rubber pad 18. Multiple T-plates 202 are slidably connected at the same horizontal height. The outer wall of the nut 207 is provided with a washer 15, and the outer wall of the washer 15 is in contact with the outer wall of the nut 207. The rubber pad 18 is used to increase the friction of the inner wall of the mounting ring 201.

[0036] Specifically, the second washer 16 forms a clearance fit with the outer wall of the mounting screw 205. By increasing the contact area with the bottom mounting surface, it effectively disperses the pressure generated when the mounting screw 205 is tightened, preventing material deformation or damage caused by local stress concentration. At the same time, it enhances the stability and reliability of the installation. The second rubber pad 18 can ensure sufficient elastic deformation to fit tightly against the surface of the fiberglass pipe without affecting the installation accuracy due to excessive thickness.

[0037] Please see the appendix Figure 2 - Appendix Figure 4 A connecting pipe 12 is slidably connected to the inner wall of the mounting ring 201 near the edge, and a connecting pipe 23 is slidably connected to the bottom of the inner wall of the mounting ring 201. Both connecting pipes 12 and 23 are pipes used for connection. A rubber pad 17 is fixedly connected to the bottom of the limiting plate 206. The bottom of the rubber pad 17 fits against the top of the connecting ring 1. The rubber pad 17 is used to buffer the structure that contacts the bottom of the limiting plate 206. Multiple rotating rods 4 are rotatably connected to the same horizontal height. A rubber ring 14 is fixedly connected to the inner wall of the connecting sleeve 11. The rubber ring 14 is used to improve the sealing and corrosion resistance of the connecting sleeve 11.

[0038] Specifically, the rubber pad 17 can effectively buffer the impact force generated when the limiting plate 206 contacts the top of the connecting ring 1, and prevent wear and noise caused by direct rigid contact between the two. The rubber ring 14 is installed on the inner wall of the connecting sleeve 11 by interference fit, ensuring that it can fit tightly to the pipeline under different pressure conditions, and achieve reliable sealing and corrosion resistance.

[0039] Working principle: When maintaining the connecting ring 1 after the connection is completed, a small amount of liquid will still leak out and come into contact with the inner wall of the connecting sleeve 11 at the joint of connecting pipe 12 and connecting pipe 2 13. Long-term contact will cause corrosion to the outer wall of the connecting sleeve 11. When maintaining, first shut off the liquid flow at connecting pipe 12 and connecting pipe 2 13. Then rotate the limiting screw 7 to remove the limiting plate 2 8 from the outer wall of the connecting ring 1, so that the limiting groove 6 and the outer wall of the limiting block 5 are separated. Then rotate the limiting block 5 to drive the rotating rod 4 to rotate, which in turn drives the positioning block 3 to rotate in the rotating groove 10, so that the position of the rotating rod 4 and the position of the positioning guide groove 9 are kept horizontal. The connecting sleeve 11 is then removed along the fit between the positioning guide groove 9 and the outer wall of the rotating rod 4 for replacement. The same steps are repeated in reverse for installation.

[0040] When installing pipes 12 and 13 with a height difference, first, place one pipe between the mounting rings 201, and then place the other pipe between the mounting rings 201 on the other side. Due to the height difference, the mounting rings 201 will be pulled, causing the T-shaped plate 202 to slide within the T-shaped guide groove 204, thereby adjusting it to a suitable position. Then, rotate the nuts 207 at both ends of the bolt 203 to lock the position of the T-shaped plate 202 and the mounting ring 201 connected to it, limiting the position of the pipe. Finally, screw the mounting screw 205 into the limiting plate 206 to fix it to the outer wall of the connecting ring 1, thereby further limiting the position of the mounting ring 201.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
