A high-strength fiberglass water supply pipe

Abstract

This utility model discloses a high-strength fiberglass reinforced plastic (FRP) water supply pipe, comprising a FRP pipe body and reinforcing components. The inner wall of the FRP pipe body is provided with an inner lining layer and a reinforcing layer from the inside out. The reinforcing components include end collars fitted at both ends of the FRP pipe body, fixing rings disposed on the outer wall of the FRP pipe body, and protrusions fixed to the inner side of the outer wall of the end collars. This high-strength FRP water supply pipe increases the thickness of the entire inner wall of the pipe through the inner lining layer and reinforcing layer, thereby enhancing the strength of the entire inner wall. Simultaneously, rotating the nut causes the threaded rod to move the end collars inward, applying inward pressure to both ends of the FRP pipe body, thus preventing circumferential cracking and further enhancing the pipe's strength.

Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically a high-strength fiberglass water supply pipeline. Background Technology

[0002] Traditional water supply pipes are mostly made of metal or plastic, which have problems such as easy corrosion, heavy weight, and insufficient pressure resistance. While fiberglass pipes have corrosion resistance, they are prone to circumferential cracking under long-term water pressure, affecting their service life and having low strength. Therefore, we propose a high-strength fiberglass water supply pipe. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the above and / or existing FRP water supply pipes, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a high-strength fiberglass water supply pipe. By setting an inner lining layer and a reinforcing layer on the inner wall of the pipe, the thickness of the entire inner wall of the pipe can be increased, thereby enhancing the strength of the entire inner wall of the pipe. At the same time, by rotating the nut, the threaded rod drives the end collar to move inward, so that the end collar applies inward pressure to both ends of the fiberglass pipe body, thereby preventing circumferential cracking of the fiberglass pipe and further enhancing the strength of the pipe.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides a high-strength fiberglass water supply pipe. By setting an inner lining layer and a reinforcing layer on the inner wall of the pipe, the thickness of the entire inner wall of the pipe can be increased, thereby enhancing the strength of the entire inner wall of the pipe. At the same time, by rotating the nut, the threaded rod drives the end collar to move inward, so that the end collar applies inward pressure to both ends of the fiberglass pipe body, thereby preventing circumferential cracking of the fiberglass pipe and further enhancing the strength of the pipe.

[0025] Figures 1-3 The diagram shown is a structural schematic of one embodiment of a high-strength fiberglass water supply pipe according to this utility model. Please refer to [link / reference]. Figures 1-3 The high-strength fiberglass water supply pipe of this embodiment includes a fiberglass pipe body 100 and a reinforcing component 200.

[0026] The inner wall of the fiberglass pipe body 100 is provided with an inner lining layer and a reinforcing layer from the inside to the outside.

[0027] The reinforcing component 200 includes end collars 210 sleeved at both ends of the fiberglass pipe body 100, a fixing ring 220 disposed on the outer wall of the fiberglass pipe body 100, a protrusion 230 fixed on the inner side of the outer wall of the end collar 210, a threaded rod 240 fixed on the inner side of the protrusion 230 and passing through the fixing ring 220, and a nut 250 threaded on the threaded rod 240. Preferably, in this embodiment, the inner wall of one end collar 210 is provided with an internal thread 211, and the outer wall of the other end collar 210 is provided with an external thread 212. The internal thread 211 and the external thread 212 are adapted to each other. The internal thread 211 and the external thread 212 facilitate the connection of two adjacent FRP pipes for splicing. The outer wall of the end collar 210 is provided with a sealing plate 213, and a sealing ring is provided on the sealing plate 213. The sealing plate 213 and the sealing ring provide a sealing function for the two connected FRP pipes to ensure their sealing performance after connection. The end collar 210 is provided with at least two protrusions 230, and each protrusion 230 is provided with a threaded rod 24. The multiple protrusions 230 and threaded rods 240 ensure that the end collar 210 stably compresses the fiberglass pipe, thereby preventing circumferential cracking of the fiberglass pipe. The fixing ring 220 is integrally formed with the fiberglass pipe body 100, which increases the thickness of the fiberglass pipe body 100 and improves its strength. A gasket is provided on the outside of the threaded rod 240. The gasket is located between the nut 250 and the fixing ring 220. The gasket between the nut 250 and the fixing ring 220 protects the surface of the fixing ring 220 and prevents the surface of the fixing ring 220 from being worn.

[0028] Combination Figures 1-3 This embodiment of a high-strength fiberglass water supply pipe is used as follows: An end collar 210 is fitted onto the end of the fiberglass pipe body 100 via a threaded rod 240. Then, the nut 250 is rotated, causing the threaded rod 240 to move the end collar 210 inwards. The end collar 210 applies inward pressure to both ends of the fiberglass pipe body 100, thereby enhancing the pipe's strength. Simultaneously, the inner lining and reinforcing layer on the inner wall of the pipe increase the thickness of the inner wall, further enhancing its strength and preventing circumferential cracking of the fiberglass pipe body 100. Two adjacent fiberglass pipe bodies 100 are threaded together by the end collars 210 at both ends via internal threads 211 and external threads 212, allowing for splicing and use of the fiberglass pipe, thus enhancing its practicality.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
