Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a multi-layer composite plastic-lined pipe fitting with a reinforced structure. Background Technology

[0002] Pipe fittings are a general term for components in a pipeline system that serve functions such as connection, control, direction change, flow diversion, sealing, and support. Pipe fittings are widely used in industrial production and civil construction, mainly to connect pipelines and provide the reliability, stability, and connection strength of the pipeline system.

[0003] Existing plastic pipe fittings are easily damaged when subjected to external impacts, leading to leaks. To address this issue, we propose a multi-layer composite plastic-lined pipe fitting with a reinforced structure. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer composite plastic-lined pipe fitting with a reinforced structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-layer composite plastic-lined pipe fitting with a reinforced structure includes a pipe fitting body, a toughening layer fixedly connected to the inner wall of the pipe fitting body, an anti-corrosion layer fixedly connected to the inner wall of the toughening layer, a reinforcing ring fixedly connected to the inner wall of the anti-corrosion layer, an outer shell provided on the outer surface of the pipe fitting body, a flame-retardant layer fixedly connected to the outer surface of the outer shell, and a plurality of slots formed on the outer surface of the pipe fitting body, each slot containing a retaining ring, and the outer surface of each retaining ring being connected to the inner wall of the outer shell.

[0007] In a further embodiment, a threaded pipe is fixedly connected to the left end of the pipe body, and a connecting pipe is fixedly connected to the right end of the pipe body, with a threaded opening slidably connected to the outer surface of the connecting pipe.

[0008] In a further embodiment, a baffle is fixedly connected to the right end of the connecting pipe, and the outer surface of the baffle is in contact with the inner wall of the screw thread.

[0009] In a further embodiment, a sealing ring is provided on the right side of the baffle, the sealing ring being located inside the screw thread, and the sealing ring being made of rubber.

[0010] In a further embodiment, the anti-corrosion layer is composed of polyethylene and epoxy resin, and the flame retardant layer is composed of a flame retardant.

[0011] In a further embodiment, the toughening layer is made of iron wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the cooperation of slots and retaining rings, allows the outer shell to be installed onto the pipe fitting body, thereby preventing damage and leakage caused by external impacts to the pipe fitting body. It thus protects the pipe fitting body. The combination of reinforcing rings and toughening layers enhances the compressive strength of the pipe fitting body. The addition of a flame-retardant layer improves the flame resistance of the outer shell, and the inclusion of an anti-corrosion layer prevents corrosive substances from directly contacting the pipe fitting body, thereby reducing corrosion.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

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.

[0022] Please see Figure 1-4 In this utility model, a multi-layer composite plastic-lined pipe fitting with a reinforced structure includes a pipe fitting body 1. A toughening layer 7 is fixedly connected to the inner wall of the pipe fitting body 1. An anti-corrosion layer 8 is fixedly connected to the inner wall of the toughening layer 7. A reinforcing ring 9 is fixedly connected to the inner wall of the anti-corrosion layer 8. An outer shell 10 is provided on the outer surface of the pipe fitting body 1. A flame-retardant layer 13 is fixedly connected to the outer surface of the outer shell 10. Several slots 2 are formed on the outer surface of the pipe fitting body 1. Each slot 2 contains a retaining ring 11, and the outer surface of the retaining ring 11 is flush with the outer shell 1. The inner wall of the outer shell 10 is connected to the inner wall of the pipe fitting 10. The cooperation of the slot 2 and the retaining ring 11 facilitates the disassembly and installation of the outer shell 10, thereby making it easy to replace the outer shell 10. The outer shell 10 can protect the pipe fitting body 1. The cooperation of the toughness layer 7 and the reinforcing ring 9 can improve the pressure resistance of the pipe fitting body 1. The flame retardant layer 13 can improve the flame resistance of the outer shell 10. The anti-corrosion layer 8 can prevent corrosive substances from directly contacting the pipe fitting body 1, thereby reducing the occurrence of corrosion.

[0023] The left end of the fitting body 1 is fixedly connected to a threaded pipe 3, which facilitates the connection between the fitting body 1 and the pipe. The right end of the fitting body 1 is fixedly connected to a connecting pipe 4. The outer surface of the connecting pipe 4 is slidably connected to a threaded end 12. Rotating the threaded end 12 facilitates the connection between the pipe and the connecting pipe 4. The right end of the connecting pipe 4 is fixedly connected to a baffle 6. The outer surface of the baffle 6 contacts the inner wall of the threaded end 12, and the baffle 6 prevents the threaded end 12 from detaching from the connecting pipe 4.

[0024] A sealing ring 5 is provided on the right side of the baffle 6. The sealing ring 5 is located inside the screw hole 12. The sealing ring 5 is supported by rubber, which can increase the sealing performance of the connection between the connecting pipe 4 and the pipeline. The anti-corrosion layer 8 is composed of polyethylene and epoxy resin, which can provide good anti-corrosion performance for the pipe body 1. The flame retardant layer 13 is composed of flame retardant, which can improve the flame retardancy of the outer shell 10. The toughness layer 7 is made of iron wire, which can increase the toughness of the pipe body 1 and make the pipe body 1 less prone to breakage.

[0025] The working principle of this utility model is as follows:

[0026] During use, the outer shell 10 is first installed on the outside of the pipe body 1 by sliding the retaining ring 11 into the retaining groove 2, thereby increasing the impact resistance of the outer wall of the pipe body 1. Then, the device is installed between the two pipes by the cooperation of the threaded pipe 3 and the threaded end 12, so that the two pipes are connected to each other, thus completing the installation work.
