Description

Technical Field

[0001] This utility model relates to glass fiber tubes, specifically a continuously wound glass fiber reinforced pressure tube for long-distance hydrophobic applications. Background Technology

[0002] Long-distance water pipelines currently primarily use ductile iron and steel pipes. However, ductile iron and steel pipes are not corrosion-resistant, and their inner surfaces corrode severely after prolonged operation, requiring regular anti-corrosion treatment, increasing maintenance costs and the impact of water outages. Fiberglass reinforced plastic (FRP) pipes have better corrosion resistance. Due to the significant elevation differences during long-distance raw water transportation, substantial water hammer effects occur, requiring higher pressure resistance, generally above 2 MPa. Currently, most FRP pipes on the market have pressure ratings below 1.6 MPa, making them prone to rupture during use. Therefore, a continuously wound fiberglass reinforced pressure pipe for long-distance drainage is proposed, which improves pressure resistance. Summary of the Invention

[0003] The purpose of this invention is to solve the above problems by proposing a continuously wound glass fiber reinforced pressure tube for long-distance hydrophobic applications.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a continuously wound glass fiber reinforced pressure tube for long-distance hydrophobic applications, comprising a tube body; characterized in that the tube body is formed by winding inner and outer layers of high linear density wound yarn and a middle layer of low linear density wound yarn; the tube body is also equipped with a connecting sleeve to facilitate connection between tube bodies; the connecting sleeve is provided with a plurality of sealing rings; each sealing ring is provided with barbs to improve the fixing effect of the tube body.

[0005] Preferably, the barbs on the sealing ring are evenly distributed on the sealing ring in a circumferential manner.

[0006] Preferably, the connecting sleeve on the pipe body includes a connecting bottom pipe for installing a sealing ring and connecting outer pipes symmetrically installed on the connecting bottom pipe.

[0007] Preferably, the connecting outer tube is further provided with a snap-fit ​​boss that is limited and connected to the tube body, and a second sealing ring provided on both sides of the snap-fit ​​boss.

[0008] Preferably, the second sealing ring is higher than the snap-fit ​​boss.

[0009] Preferably, the tube body is provided with an insertion part and a socket adapted to connect to the outer tube; the socket is provided with a snap-fit ​​groove adapted to the snap-fit ​​protrusion.

[0010] The beneficial effects of this utility model are as follows: by winding the inner and outer layers of the tube with high linear density winding yarn and the middle layer with low linear density winding yarn, the circumferential tensile strength of the tube is improved, as well as the pressure resistance and water hammer resistance of the tube.

[0011] By setting barbs on the sealing ring, the friction between the pipe body and the connecting sleeve is increased, thereby improving the sealing performance and the strength of the connection between the pipe body and the connecting sleeve. Attached Figure Description

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the present invention of a continuously wound glass fiber reinforced pressure tube for long-distance hydrophobic applications.

[0017] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0018] See appendix Figure 1-3As shown in the figure, this embodiment of a continuously wound glass fiber reinforced pressure tube for long-distance hydrophobic applications includes a tube body 1. The tube body 1 is characterized by being wound with inner and outer layers of high-density wound yarn 101 and an inner layer of low-density wound yarn 102. A connecting sleeve 2 is also installed on the tube body 1 to facilitate connection between tube bodies 1. The connecting sleeve 2 contains several sealing rings 3. Each of the sealing rings has a barb structure 301 to improve the fixing effect of the tube body 1. The barb structures 301 on the sealing rings 3 are evenly distributed circumferentially on the sealing rings 3. The fact that the tube body 1 is wound with inner and outer layers of high-density wound yarn 101 and an inner layer of low-density wound yarn 102 improves the circumferential tensile strength of the tube body 1, enhancing its pressure resistance and water hammer resistance. The barb structures 301 on the sealing rings 3 increase the friction between the tube body 1 and the connecting sleeve 2, thereby improving the sealing performance and the firmness of the connection between the tube body 1 and the connecting sleeve 2.

[0019] See appendix Figure 3 As shown, the connecting sleeve 2 on the pipe body 1 includes a connecting bottom pipe 201 for mounting a sealing ring 3 and a connecting outer pipe 202 slidably and symmetrically mounted on the connecting bottom pipe 201; the connecting outer pipe 202 is also provided with a snap-fit ​​boss 204 that is limited and connected to the pipe body 1 and a second sealing ring 205 provided on both sides of the snap-fit ​​boss 204; the second sealing ring 205 is higher than the snap-fit ​​boss 204; the pipe body 1 is provided with an insertion part 104 and a socket 105 adapted to the connecting outer pipe 202; the socket 105 is provided with a snap-fit ​​groove 106 adapted to the snap-fit ​​boss 204; by inserting the insertion part 104 on the pipe body 1 into the connecting bottom pipe 201, the connecting outer pipe 202 can be connected to the connecting pipe 1. Inside the tube 1, the socket 105 is inserted into the connecting outer tube 202. The socket 105 compresses the second sealing ring 205 inside the connecting outer tube 202, making the snap-fit ​​boss 204 higher than the second sealing ring 205, until the snap-fit ​​groove 106 on the socket 105 is inserted into the snap-fit ​​boss 204, so that the snap-fit ​​boss 204 is snapped into the snap-fit ​​groove 106, thus limiting the connection between the tube body 1 and the connecting outer tube 202, and also preventing the tube body 1 from moving backward; at the same time, the second sealing ring 205 seals the connection between the tube body 1 and the connecting outer tube 202, thereby facilitating the connection between the connecting sleeve 2 and the tube body 1, and further facilitating the connection between the tube bodies 1 and the tube body 1.

[0020] The installation process of this utility model is as follows: First, the insertion part 104 of the tube body 1 is inserted into the connecting bottom tube 201, so that the outer wall of the insertion part 104 contacts the barb structure 301 on the sealing ring 3, thereby increasing the friction between the outer wall of the insertion part 104 and the sealing ring 3. Then, the receiving platform 105 is inserted into the connecting outer tube 202, and the receiving platform 105 squeezes the second sealing ring 205 in the connecting outer tube 202, so that the snap-fit ​​boss 204 is higher than the second sealing ring 205, until the snap-fit ​​groove 106 on the receiving platform 105 is inserted into the snap-fit ​​boss 204, so that the snap-fit ​​boss 204 is snapped into the snap-fit ​​groove 106, thereby connecting the tube body 1 with the connecting outer tube 202 and the connecting bottom tube 201.

[0021] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
