Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic pipeline connection, in particular to a glass fiber reinforced plastic pipeline structure which is easy to connect. Background Art

[0002] When it comes to the connection technology of FRP pipes, it is a critical process to ensure the integrity, sealing and durability of the pipe system. However, in actual operation, especially when connecting two FRP pipes, traditional connection methods such as wrapping may expose some obvious limitations.

[0003] First, regarding sealing performance, although the wrapping and docking method can theoretically achieve pipe connection, in actual applications, its sealing effect is often unsatisfactory. This is mainly because the resin or material used for wrapping is greatly affected by environmental factors during the curing process. For example, fluctuations in temperature and humidity may lead to incomplete curing and even tiny cracks. These cracks will undoubtedly weaken the sealing performance of the pipeline and increase the risk of leakage. In addition, the number of layers and tightness of the wrapping are also important factors affecting the sealing effect. If the number of layers is insufficient or the tightness is not enough, the sealing performance will also be reduced and the possibility of leakage will increase.

[0004] Secondly, the wrapping connection method also has certain deficiencies in protecting the alignment of the structure. During the docking process, if there is a deviation in the port position, angle or size of the two pipes, it is difficult to achieve perfect alignment and sealing by wrapping alone. This misalignment not only affects the sealing performance of the pipeline, but also increases the risk of failure of the pipeline during operation. Especially when the pipeline is subjected to pressure or temperature changes, the misaligned connection is more likely to crack or loosen, further increasing the risk of leakage.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The integrated design of the connector and the "L"-shaped design of the fixing ring greatly simplify the installation process. The installer only needs to follow the steps to easily complete the pipe connection, which improves work efficiency.

[0021] Due to the stability and sealing of the connection structure, as well as the easy installation and strong expansibility, the FRP pipe connection structure can reduce the frequency of maintenance and replacement due to connection problems, thereby extending the service life of the pipeline system.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0029] like Figures 1 to 5As shown in the figure, we introduce in detail a fiberglass pipe structure that is carefully designed for easy connection. This structure mainly consists of two main parts: fiberglass pipe A1 and fiberglass pipe B2, which are characterized by having the same diameter, ensuring smooth and matching during connection.

[0030] In order to achieve a stable connection between the two pipes, we introduced the key component of the connector 3. The connector 3 consists of a fixing ring 31 and a sealing ring 36. The inner side of the fixing ring 31 is designed with a sealing chamber 34, and the chamber wall of the sealing chamber 34 is cleverly provided with a convex ring 35. It is worth noting that at the junction of the sealing chamber 34 and the convex ring 35, we installed a sealing ring 36 to ensure the tightness and sealing of the connection. In addition, the inner end of the fixing ring 31 is designed with a threaded portion 37, which is matched with a sealing threaded ring 38, which is tightly sleeved on the threaded portion 37.

[0031] In the actual installation process, the FRP pipe A1 and the FRP pipe B2 are respectively installed on two corresponding fixing rings 31. The two fixing rings 31 are provided with round holes, and the connecting screws 32 are inserted into these round holes and tightly fixed to the fixing rings 31 with the fastening nuts 33, thereby ensuring a stable connection between the pipes and the fixing rings 31. More importantly, the two corresponding sealing threaded rings 38 can be seamlessly butted, completely covering the butt joint of the FRP pipe A1 and the FRP pipe B2, further enhancing the overall sealing performance.

[0032] In order to ensure the durability and stability of the connection, we filled the joint of the FRP pipe A1 and the FRP pipe B2 with sealing filler and fixed it by hot melting. At this time, the two sealing thread rings 38 are like two protective covers, which firmly wrap the hot-melted sealing filler inside, forming an indestructible defense line.

[0033] The inner wall of the sealing threaded ring 38 is designed with threads, which are perfectly matched with the threaded portion 37 of the fixing ring 31. In addition, a rubber ring is also provided at the seamless joint of the two corresponding sealing threaded rings 38 to further enhance the sealing effect.

[0034] In terms of structural design, the convex ring 35, the fixing ring 31 and the threaded portion 37 are designed as one body, which not only ensures the strength of the connection, but also greatly simplifies the installation process. The cross section of the fixing ring 31 is designed in an "L" shape, which makes it more stable when subjected to external forces. The edge of the convex ring 35 is designed in an arc shape, which is not only beautiful, but also reduces damage to the pipe during the connection process.

[0035] As for the sealing ring 36, it is perfectly matched with the convex ring 35 and the fixing ring 31, and is firmly fixed on the fixing ring 31 by adhesive. At the same time, the sealing ring 36 is also sleeved on the FRP pipe A1 and the FRP pipe B2, and is tightly connected with them by adhesive, ensuring good sealing performance under any circumstances. Example

[0036] On the basis of the first embodiment, we further optimized and improved the FRP pipe structure. Specifically, we added connectors 3 to both ends of the FRP pipe A1 or the FRP pipe B2, which means that both pipes have stronger scalability and connection capabilities.

[0037] In order to achieve this function, we use connecting screws 32 with increased length between two fixing rings 31 on the FRP pipe A1 or FRP pipe B2 for fixing. These connecting screws 32 with increased length are distributed in a ring shape on the FRP pipe A1 or FRP pipe B2 to form a solid supporting structure. This design not only enhances the overall strength of the pipe, but also provides more possibilities for its use in complex environments.

[0038] Through such a design, the FRP pipe A1 or FRP pipe B2 can be better protected and supported when subjected to external impact or vibration, thereby greatly extending its service life and safety.

[0039] Connection process: Confirm that the diameters of FRP pipe A1 and FRP pipe B2 are the same to ensure smooth connection. Prepare the connection piece 3, including a fixing ring 31, a sealing ring 36, a connecting screw 32, a tightening nut 33 and a sealing thread ring 38.

[0040] The glass fiber reinforced plastic pipe A1 and the glass fiber reinforced plastic pipe B2 are respectively placed in the sealing chambers 34 of the two fixing rings 31. Ensure that the convex ring 35 of the fixing ring 31 is tightly fitted with the outer wall of the pipe.

[0041] The sealing ring 36 is placed at the junction of the sealing chamber 34 and the convex ring 35. Adhesive is used to ensure that the sealing ring 36 is firmly connected to the fixing ring 31.

[0042] Insert the connecting screw 32 into the circular hole of the fixing ring 31. Use the fastening nut 33 to tightly fix the connecting screw 32 and the fixing ring 31 to ensure a stable connection between the pipeline and the fixing ring 31.

[0043] The sealing threaded ring 38 is sleeved on the threaded portion 37 of the fixing ring 31. It is ensured that the two corresponding sealing threaded rings 38 are seamlessly butted together and completely cover the butt joint of the FRP pipe A1 and the FRP pipe B2.

[0044] The sealing filler is filled into the butt joint of the FRP pipe A1 and the FRP pipe B2, and fixed by hot melting, while two sealing thread rings 38 wrap the hot melted sealing filler.

[0045] Check the entire connection to ensure there is no leakage. If necessary, further reinforce or adjust the position of the connector 3. After the connection is completed, the FRP pipe A1 and the FRP pipe B2 will form a stable and sealed overall structure.

[0046] On the basis of Example 1, in order to enhance the expansibility and connection capacity of the FRP pipe, connectors 3 can be added to both ends of the FRP pipe and fixed with connecting screws 32 of increased length, thereby forming a solid support structure and improving the overall strength and safety of the pipe.

[0047] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0048] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
