[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] The present embodiment relates to a leak-proof glass fiber reinforced plastic pipe, which is designed to improve the sealing performance when pipes are connected to each other or to other components, thereby improving the leak-proof performance of the pipe.

[0032] In terms of overall structure, Figure 1-Figure 2 As shown, the leak-proof FRP pipe includes a pipe body 1, a connecting part 2 and a leak-proof part 3; the connecting part 2 is connected to the end of the pipe body 1 and is configured to connect the pipe body 1 with other components; the leak-proof part 3 is located between the connecting part 2 and the pipe body 1, and when the medium in the pipe body 1 flows, the leak-proof part 3 is tightly connected to the pipe body 1.

[0033] The leak-proof FRP pipe described in the embodiment of the present application is provided with a connecting portion 2 to improve the stability of the connection between the pipe body 1 and the pipe body 1, or between the pipe body 1 and other components, so as to prevent the unstable connection between the pipe body 1 and other components from leaking when the pipe body 1 is transported horizontally and is in a heavy load or under-supported state; and the leak-proof portion 3 is provided to improve the sealing between the pipe body 1 and the connecting portion 2; thereby improving the connection stability and sealing after the pipe body 1 is connected to other components; and finally improving the leak-proof performance of the pipe.

[0034] Based on the above overall introduction, the connecting portion 2 described in this embodiment is as follows Figure 2 and Figure 3 As shown; the connecting part 2 includes: a connecting ring plate 21, a stopper 22, a sleeve 23 and an elastic gasket 24. Specifically, the connecting ring plate 21 has a through hole 211, and the diameter of the through hole 211 is not greater than the outer diameter of the tube body 1; the stopper 22 is connected to the connecting ring plate 21 and inserted into the tube body 1 so that the tube body 1 is directly opposite to the through hole 211; the sleeve 23 is tightly connected to the connecting ring plate 21, and the sleeve 23 is directly opposite to the through hole 211 and sleeved outside the stopper 22, and the tube body 1 can be inserted into the sleeve 23. The elastic gasket 24 is inserted between the stopper 22 and the sleeve 23 with interference fit, and the elastic gasket 24 is configured to form a concave area to wrap the end face of the tube body 1 when the tube body 1 is pressed tightly.

[0035] like Figure 2 and Figure 3 As shown, when the connecting portion 2 is connected to the tube body 1, the diameter of the through hole 211 is not larger than the diameter of the tube body 1, so as to prevent the tube body 1 from passing through the connecting ring plate 21. The limiting member 22 can be made of a round tube, which is directly opposite to the through hole 211 of the connecting ring plate 21 and is sealed and fixedly connected to the connecting ring plate 21. In this embodiment, the round tube and the connecting ring plate 21 can be fixedly connected by welding. Alternatively, the limiting member 22 can also be a rod-shaped, tubular or columnar object, which is fixed on the limiting ring plate at equal distances along the circumference of the through hole 211. The elastic gasket 24 can be made of rubber or silicone as a raw material, which can form a concave area when the tube body 1 is pressed tightly, and can wrap the tube body 1 under its own resilience.

[0036] The setting of the stopper 22 facilitates the pre-connection of the pipe body 1 and the connecting part 2, facilitates the subsequent closed installation of the pipe body 1, and ensures the stability of the connection between the pipe body 1 and other components when the pipe body 1 bears a large load or the bottom of the pipe body 1 is undersupported and in a suspended state; the sleeve 23 can reduce the damage caused by the external environment to the end of the pipe body 1. By setting the elastic gasket 24, the flow of the circulating medium in the pipe body 1 to the space between the pipe body 1 and the sleeve 23 is reduced. Finally, the stability of the pipeline in use and the leak-proof performance are improved.

[0037] In order to improve the sealing performance between the tube body 1 and the connecting part 2 and realize the sealing connection between the tube body 1 and the connecting part 2 of different models, the leak-proof part 3 is arranged as follows: Figure 2 and Figure 3 As shown, the leak-proof part 3 includes a sealing part 31 and a limit-keeping part 32; the sealing part 31 is located between the sleeve 23 and the tube body 1, and seals and connects the sleeve 23 and the tube body 1; the limit-keeping part 32 connects the sealing part 31 and the sleeve 23, and the limit-keeping part 32 is configured to adjust and maintain the relative position of the sealing part 31 and the tube body 1.

[0038] Specifically, Figure 2 and Figure 3 As shown, the sealing part 31 includes an elastic plug ring 311 and a sealing ring 312. The elastic plug ring 311 can be elastically inserted and squeezed between the sleeve 23 and the tube body 1 to form a detachable connection; the sealing ring 312 is embedded in the elastic plug ring 311, and the center line of the sealing ring 312 in the length direction is colinear with the center line of the elastic plug ring 311 and connected to the limit holding part 32. The elastic plug ring 311 is a truncated cone structure that allows the tube body 1 to pass through along its length direction. The elastic plug ring 311 can be made of rubber as a raw material. When in use, the small end of the elastic plug ring 311 is first inserted between the tube body 1 and the sleeve 23. Under the pushing action of the limit holding part 32 and the guiding action of the outer cone surface of the elastic plug ring 311, it can be deformed and gradually inserted between the tube body 1 and the sleeve 23, and the elastic plug ring 311 itself is pressed against the tube body 1 and the sleeve 23 under its own rebound performance.

[0039] like Figure 2 and Figure 3 As shown, in order to push the elastic plug ring 311, the relative position between the elastic plug ring 311, the sleeve 23 and the tube body 1 is adjusted and maintained; the position limiting and maintaining part 32 is arranged as follows, specifically, the position limiting and maintaining part 32 includes a position limiting block 321, a connecting plate 322 and an adjusting locking member 323, the position limiting block 321 is fixedly connected to the sleeve 23, and in this embodiment, it can be fixedly connected to the end of the circumferential outer wall of the sleeve 23 away from the connecting ring plate 21; the connecting plate 322 is fixedly connected to the sealing ring 312, and in this embodiment, the connecting plate 322 is fixedly connected to the end surface of the sealing ring 312 close to the large end of the elastic plug ring 311. The adjusting locking member 323 can adjust and maintain the distance between the position limiting member 22 and the connecting plate 322. In this embodiment, the adjusting locking member 323 can be a bolt. During installation, one end of the bolt passes through the connecting plate 322 and is threadedly connected to the position limiting block 321, and the other end of the bolt is pressed against the side wall of the connecting plate 322 away from the position limiting plate. Thereby, the relative position of the leak-proof part 3 and the connecting part 2 is adjusted and maintained, thereby improving the leak-proof performance of the pipeline.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
