Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a Teflon corrugated pipe. Background Art

[0002] Bellows are a type of connecting pipe commonly used in daily life. These pipes are mainly used to discharge or transport flowing liquids.

[0003] According to observations based on existing technology, this pipeline is widely used in industry and chemical industry. The liquids that need to be transported in industry are often accompanied by high heat and strong corrosiveness. Under long-term high-pressure environment, ordinary bellows may wear and melt, which will cause pipeline leakage and prevent normal transportation. It will also cause certain safety hazards in the production and processing process, and will also have a certain impact on the quality of production and processing. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A Teflon corrugated pipe comprises a sleeve, one side of the sleeve is fixedly connected to a connecting pipe, the surface of the connecting pipe is fixedly connected to an external thread, one end of the sleeve is fixedly connected to a braided tube, one side of the sleeve is fixedly connected to a limiting ring, the inner wall of the braided tube is fixedly connected to a corrugated sleeve, a wear-resistant layer is pressed on the surface of the corrugated sleeve, a reinforcement layer is pressed on one side of the wear-resistant layer, and a corrosion-resistant layer is pressed on one side of the reinforcement layer.

[0007] Preferably, one end of the connecting pipe is threadedly connected with a fixing nut.

[0008] Preferably, the wear-resistant layer is made of polytetrafluoroethylene.

[0009] Preferably, the reinforcement layer is made of heat-resistant polyethylene.

[0010] Preferably, the corrosion-resistant layer is made of epoxy resin.

[0011] Preferably, the surface of the braided tube is coated with inositol hexaphosphate.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are:

[0013] 1. The utility model provides a corrugated sleeve. By providing the corrugated sleeve inside the braided tube, the pipe can be made into a double-layer pipe. The braided tube on the surface can play a protective and anti-rust role, and the internal corrugated tube is not subject to external erosion, which effectively increases the service life of the corrugated tube, improves the use pressure, and is suitable for more working environments.

[0014] 2. A protective layer is provided in the utility model. The wear-resistant layer can enhance the wear resistance of the corrugated pipe. If there are impurities in the transported liquid, the friction of the impurities on the inner wall of the pipe can be resisted, thereby effectively improving the wear resistance of the inner wall of the pipe. The reinforcement layer can resist high temperature, and can ensure that the pipe will not be melted when transporting high-temperature liquid. The pipe can withstand temperatures ranging from -70 to 260 degrees. The corrosion-resistant layer can make the pipe resistant to corrosion, thereby effectively enhancing the service life of the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0020] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0021] A Teflon bellows provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3As shown, the utility model provides a Teflon corrugated tube, including a sleeve 1, one side of the sleeve 1 is fixedly connected to a connecting tube 10, the surface of the connecting tube 10 is fixedly connected to an external thread 2, one end of the sleeve 1 is fixedly connected to a braided tube 4, one side of the sleeve 1 is fixedly connected to a limiting ring 9, the inner wall of the braided tube 4 is fixedly connected to a corrugated sleeve 5, and one end of the connecting tube 10 is threadedly connected to a fixing nut 3.

[0023] In the first embodiment, one end of the sleeve 1 is fixedly connected to a connecting pipe 10, and the external thread 2 on the connecting pipe 10 is engaged with the fixing nut 3. The fixing nut 3 can be adapted to multiple types of pipe connectors. The braided tube 4 is provided so that the pipe can work in multiple scenarios. The limiting ring 9 can limit and fix the corrugated sleeve 5, thereby avoiding displacement of the corrugated sleeve 5 during use, thereby ensuring the service life of the pipe.

[0024] A wear-resistant layer 6 is pressed on the surface of the corrugated sleeve 5, a reinforcement layer 7 is pressed on one side of the wear-resistant layer 6, and a corrosion-resistant layer 8 is pressed on one side of the reinforcement layer 7. The wear-resistant layer 6 is made of polytetrafluoroethylene, the reinforcement layer 7 is made of heat-resistant polyethylene, the corrosion-resistant layer 8 is made of epoxy resin, and the surface of the braided tube 4 is coated with inositol hexaphosphate.

[0025] In the second embodiment, the surface strength of the bellows 5 can be improved by setting a wear-resistant layer 6. When twisting or adjusting the angle of the pipe, the bellows 5 will rub against the inner wall of the braided tube 4. At the same time, during transportation, the liquid passing through the bellows 5 will also cause the bellows 5 to vibrate. During vibration, the bellows 5 will also rub against the braided tube 4. The improved wear-resistant effect can ensure the wear resistance of the bellows 5, so that the bellows 5 will not leak too quickly during transportation. The reinforcement layer 7 can improve the heat and cold resistance of the bellows 5, and it can be used normally in extreme weather without the pipe rupture due to the large temperature difference between the inside and the outside. The corrosion-resistant layer 8 can improve the corrosion resistance of the pipe, thereby enhancing the service life of the pipe.

[0026] The working principle and use process of the utility model are as follows: the fixing nut 3 can be fixed to the joint of the connecting pipe 10 by rotating, and the corrugated sleeve 5 can be fixed by a limiting ring 9 at one end of the connecting pipe 10. After the braided tube 4 is sleeved on the surface of the corrugated sleeve 5, the corrugated sleeve 5 can be protected, and the wear-resistant layer 6 can be provided to increase the wear resistance of the corrugated sleeve 5, the reinforcement layer 7 can increase the heat and cold resistance of the corrugated sleeve 5, the corrosion-resistant layer 8 can increase the corrosion resistance of the pipeline, and improve the service life of the corrugated sleeve 5, and the coating on the surface of the braided tube 4 can delay rusting of the braided tube 4, thereby ensuring the service life and improving its own strength.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
