Description

Technical Field

[0001] This utility model relates to the field of corrugated pipes, specifically a dual-channel corrugated pipe. Background Technology

[0002] Corrugated pipes mainly include metal corrugated pipes, corrugated expansion joints, corrugated heat exchange tubes, diaphragms, and metal hoses. Metal corrugated pipes are mainly used to compensate for pipeline thermal deformation, damping, and absorbing pipeline settlement deformation. They are widely used in petrochemical, instrumentation, aerospace, chemical, power, water conservancy, and metallurgical industries. Corrugated pipes made of plastic and other materials play an irreplaceable role in media transportation, power wiring, machine tools, and home appliances.

[0003] In existing solutions, most corrugated pipes have only one channel inside. If two liquids need to be transported, two separate sets of pipes need to be laid. In space-constrained environments, this will occupy a lot of valuable space, making the overall layout very complex, crowded and cumbersome, and also increasing installation time and labor costs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most corrugated pipes have only one channel inside. If two liquids need to be transported, two independent pipes need to be laid. In space-constrained environments, this will occupy a lot of valuable space, making the overall layout very complex, crowded and cumbersome, and also increasing the installation time and labor costs. This utility model proposes a dual-channel corrugated pipe.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-channel corrugated pipe, including a corrugated pipe body, wherein a partition is provided in the inner cavity of the corrugated pipe body.

[0006] Preferably, a rubber pad is fixedly connected to the surface of the partition, and the surface of the rubber pad is fixedly connected to the inner cavity of the corrugated pipe body.

[0007] Preferably, the top and the top of the partition are fixedly connected to a support column, and there are several support columns. The surface of the support column is fixedly connected to the inner cavity of the corrugated pipe body.

[0008] Preferably, the bottom of the partition is provided with a sound-absorbing groove, and the number of the sound-absorbing grooves is several.

[0009] Preferably, a woven reinforcing mesh is movably fitted onto the surface of the corrugated pipe body, and the woven reinforcing mesh is made of stainless steel.

[0010] The advantages of this utility model are:

[0011] This invention uses a corrugated pipe body and a baffle plate in combination to separate two independent channels inside the corrugated pipe, allowing for the transport of two different fluids. This solves the problem that in existing solutions, most corrugated pipes only have one channel inside. If two liquids need to be transported, two separate pipes need to be laid. In space-constrained environments, this would occupy a lot of valuable space, making the overall layout very complex, crowded, and cumbersome, and also increasing installation time and labor costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0020] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0021] This application discloses a dual-channel bellows. (Refer to...) Figure 1 and Figure 5 A dual-channel corrugated pipe includes a corrugated pipe body 1, and a partition 3 is provided in the inner cavity of the corrugated pipe body 1.

[0022] Reference Figure 5 A rubber pad 6 is fixedly connected to the surface of the partition 3. The surface of the rubber pad 6 is fixedly connected to the inner cavity of the bellows body 1. The rubber pad 6 is used to prevent the thermal expansion coefficients of the partition 3 and the main body material of the bellows body 1 from being different. When the temperature changes, the expansion or contraction of the two materials will be different, which will generate huge internal stress at the rigid connection point, causing the connection to crack or deform.

[0023] Reference Figure 2 and Figure 3 The top and the top of the partition 3 are fixedly connected with support columns 4. There are several support columns 4. The surface of the support column 4 is fixedly connected to the inner cavity of the corrugated pipe body 1. The support columns 4 provide a fixed support effect for the partition 3 and improve the stability of the partition 3 during operation.

[0024] Reference Figure 3 The bottom of the partition 3 is provided with a sound-absorbing groove 5. There are several sound-absorbing grooves 5. By setting the sound-absorbing grooves 5, several sound-absorbing structures are formed. When the liquid flows or the pipe vibrates and generates noise, the sound waves cancel each other out in the cavity of the sound-absorbing groove 5, which significantly reduces the noise.

[0025] Reference Figure 1 The surface of the corrugated pipe body 1 is movably fitted with a braided reinforcing mesh 2, which is made of stainless steel. By setting the braided reinforcing mesh 2, the pressure resistance and impact resistance of the pipe are improved while maintaining the flexibility of the corrugated pipe body 1.

[0026] Working Principle: In existing corrugated pipes, there is generally only one single channel for transporting liquid. In this case, a partition 3 is fixedly connected inside the corrugated pipe body 1 by a rubber gasket 6, dividing the inside of the corrugated pipe body 1 into two independent transport channels. The partition 3 is supported by a support column 4, increasing the stability of the connection between the partition 3 and the inner wall of the corrugated pipe body 1. When the corrugated pipe body 1 is buried underground, the woven reinforcing mesh 2 that is movably fitted on the surface of the corrugated pipe body 1 can be shortened at both ends according to the usage requirements, facilitating the connection between the corrugated pipe body 1 and other components. The connection is made, and the braided reinforcing mesh 2, while maintaining the flexibility of the corrugated pipe body 1, greatly improves the pressure resistance and impact resistance of the corrugated pipe body 1, preventing the corrugated pipe body 1 from being crushed or punctured by sharp objects. It is suitable for high pressure or harsh working conditions. After installation, the two independent channels inside the corrugated pipe body 1 can transport different liquids respectively, and the silencing groove 5 can silence the conveying channel at the bottom of the corrugated pipe body 1. When the fluid flows or the corrugated pipe body 1 vibrates and generates noise, the sound waves cancel each other out in the cavity through the silencing groove 5, significantly reducing the noise.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
