Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, and more particularly to a corrugated pipe with high flexibility. Background Art

[0002] In modern industrial and civil fields, bellows, as an important pipe connection and transmission component, are widely used due to their good flexibility, pressure resistance, corrosion resistance and sealing. Bellows are widely used in many industries such as petroleum, chemical industry, natural gas transportation, aerospace, automotive industry and building drainage. They are used to connect different equipment or pipelines to achieve safe and efficient transmission of fluids or gases. The flexibility of bellows is particularly important, especially in situations where frequent bending, vibration or complex stress are required.

[0003] Insufficient existing technology: Although traditional bellows have a certain degree of flexibility, under extreme working conditions, such as large-angle bending, high-frequency vibration or extreme temperature changes, their flexibility may not be sufficient to meet the requirements, which may easily lead to pipeline fatigue, rupture or leakage. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bellows with high flexibility to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highly flexible corrugated pipe, comprising a corrugated pipe body, the side of the corrugated pipe body being fixedly connected to the outer wall of the corrugated pipe, the side of the outer wall of the corrugated pipe being corrugated, the side of the outer wall of the corrugated pipe being fixedly connected to the inner liner of the corrugated pipe, the side of the corrugated pipe body being fixedly connected to a connecting device, and the side of the connecting device being fixedly connected to an anti-slip joint.

[0006] Furthermore, the corrugated pipe body includes a resin outer layer, a polyethylene layer and a silicone inner layer. The side surface of the resin outer layer is fixedly connected to the polyethylene layer, and the side surface of the polyethylene layer is fixedly connected to the silicone inner layer.

[0011] The technical effects and advantages of this utility model are:

[0012] 1. This utility model effectively enhances the overall flexibility and pressure resistance of the bellows through the combined structure of a bellows outer wall and a bellows inner liner. The corrugated outer wall design not only gives the bellows greater deformation capacity, but also evenly distributes stress when subjected to external pressure, reducing the risk of rupture. At the same time, the presence of the bellows inner liner further ensures the structural strength and sealing of the tube body, ensuring the stability and safety of fluids or gases during transmission.

[0013] 2. The utility model adopts a resin outer layer, a polyethylene layer and a silicone inner layer through the main body, which has high flexibility. There are gaps between adjacent corrugated rings so that it can be bent at will.

[0014] 3. This utility model greatly facilitates the connection of the corrugated pipe to other pipe fittings by providing a connecting device, including an interface disc, threaded holes, a sealing ring, and an anti-corrosion coating.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The highly flexible corrugated tube involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 4 The utility model provides a corrugated pipe with high flexibility, including a corrugated pipe body 1, the side of the corrugated pipe body 1 is fixedly connected to the corrugated pipe outer wall 2, the side of the corrugated pipe outer wall 2 is corrugated, the side of the corrugated pipe outer wall 2 is fixedly connected to the corrugated pipe inner liner 3, the side of the corrugated pipe body 1 is fixedly connected to the connecting device 4, and the side of the connecting device 4 is fixedly connected to the anti-slip joint 5. The corrugated pipe body 1 serves as the core bearing component, and the corrugated pipe outer wall 2 fixedly connected to the side thereof achieves good flexibility. The corrugated design of the corrugated pipe outer wall 2 not only enhances the bending ability of the pipe body, but also improves its fatigue resistance, so that the corrugated pipe can adapt to various complex and changeable installation environments. The corrugated pipe inner liner 3 serves as an internal supporting structure to ensure the stability and safety of the pipe body under high pressure or high stress. The introduction of the connecting device 4 enables the corrugated pipe to be conveniently and reliably connected to other pipes or equipment, and the anti-slip joint 5 fixed on its side not only increases the stability of the connection, but also facilitates installation and disassembly, thereby improving work efficiency.

[0022] Among them, the bellows body 1 includes a resin outer layer 101, a polyethylene layer 102 and a silicone inner layer 103. The side of the resin outer layer 101 is fixedly connected with the polyethylene layer 102, and the side of the polyethylene layer 102 is fixedly connected with the silicone inner layer 103. The resin outer layer 101, as the outermost layer, provides excellent wear resistance, corrosion resistance and weather resistance, effectively resists physical and chemical erosion in the external environment, and protects the internal structure from damage. The polyethylene layer 102, as the intermediate layer, not only enhances the overall strength and toughness of the pipe body, but also improves its impact resistance and pressure resistance, ensuring that the bellows can still maintain a stable shape under complex working conditions. The silicone inner layer 103, with its excellent sealing, high temperature resistance and chemical stability, provides a safe and pollution-free channel for the transmission medium, ensuring the purity and transmission efficiency of the fluid or gas.

[0023] Among them, an elastic sheath 201 is fixedly connected to the side of the outer wall 2 of the bellows, a recessed groove 202 is opened on the side of the outer wall 2 of the bellows, and a corrugated ring 203 is fixedly connected to the side of the outer wall 2 of the bellows. The elastic sheath 201 is tightly attached to the outer wall, which not only provides additional protection to prevent external mechanical impact and scratches, but also can buffer the stress caused by thermal expansion and contraction when the temperature changes, thereby extending the service life of the bellows. The design of the recessed groove 202 helps to increase the flexibility and bending ability of the outer wall, so that the bellows can be flexibly laid in complex paths, and the fixation of the corrugated ring 203 strengthens the structural strength of the pipe body, prevents excessive deformation or rupture under high pressure or high stress environment, and ensures the stability and safety of the bellows under various working conditions.

[0024] Among them, the connecting device 4 includes an interface disc 401, a threaded hole 402, a sealing ring 403 and an anti-corrosion coating 404. The side of the corrugated pipe body 1 is fixedly connected with the interface disc 401. The connecting device 4 is composed of the key components of the interface disc 401, the threaded hole 402, the sealing ring 403 and the anti-corrosion coating 404. These components work together to achieve efficient and reliable connection. The interface disc 401, as the core component of the connecting device 4, is firmly fixed to the side of the corrugated pipe body 1, providing a stable foundation for the connection.

[0025] Among them, a threaded hole 402 is opened on the side of the interface disc 401, and a sealing ring 403 is fixedly connected to the side of the interface disc 401. The threaded hole 402 opened on the side of the interface disc 401 allows the use of bolts or other fasteners, and is tightly connected to the pipe to be connected through threaded matching. In order to prevent fluid or gas leakage at the connection, a sealing ring 403 is also fixedly connected to the side of the interface disc 401. The sealing ring 403 is made of highly elastic and wear-resistant material, can be effectively compressed during the connection process, and fits tightly between the connection surfaces to form a reliable sealing barrier.

[0026] Among them, the outer surface of the interface disc 401 is sprayed with an anti-corrosion coating 404, and the side of the sealing ring 403 is fixedly connected with an anti-slip joint 5. The anti-corrosion coating 404 can effectively resist the erosion of various corrosive media and protect the interface disc 401 from damage. At the same time, the side of the sealing ring 403 is also fixedly connected with an anti-slip joint 5. The joint adopts an anti-slip design, which can increase the stability and safety of the connection and prevent slipping or loosening during the connection process.

[0027] The working principle of the present invention: the bellows body 1, as the core structure, is composed of three layers of materials: a resin outer layer 101, a polyethylene layer 102 and a silicone inner layer 103. This not only gives the pipe body excellent corrosion resistance, wear resistance and temperature resistance, but also ensures the sealing and transmission stability of the fluid through the silicone inner layer 103. The corrugated design of the bellows outer wall 2 on the side of the pipe body increases the flexibility of the pipe body and can flexibly adapt to various bending and vibration environments. The reinforcement of the elastic sheath 201 and the bellows ring 203 further enhances the pressure resistance and stability of the outer wall. The recessed groove 202 may also play a role in reducing weight and increasing bending flexibility. The bellows liner 3 enhances the structural strength of the entire bellows. Through the close connection with the bellows outer wall 2, the liner can withstand the pressure from the inside of the pipeline to prevent the pipe body from being under high pressure. Deformation or rupture, the connecting device 4 is a key component for connecting the bellows to other bellows, and is composed of an interface disc 401, a threaded hole 402, a sealing ring 403 and an anti-corrosion coating 404. The interface disc 401 provides a stable connection basis, and the threaded hole 402 opened thereon allows it to be tightly connected to other components through threaded fastening, ensuring the reliability and sealing of the connection. The sealing ring 403 fits tightly at the interface, effectively preventing the leakage of fluid or gas, and further improving the safety of the connection. In addition, the anti-corrosion coating 404 on the outer surface of the interface disc 401 can resist corrosion factors in harsh environments and extend the service life of the connecting device 4. The setting of the anti-slip joint 5 makes the connection operation more convenient, and the docking can be easily completed even under wet or harsh working conditions, ensuring the efficient operation of the bellows system.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
