Description

Technical Field

[0001] The utility model relates to the technical field of impact-resistant spiral bellows, in particular to an impact-resistant spiral bellows. Background Art

[0002] Double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. At present, its production process and application technology are very mature.

[0003] Although there are many types and quantities of double-wall corrugated pipes at present, there are still certain problems with the existing double-wall corrugated pipes, which bring certain inconveniences to the use of the double-wall corrugated pipes.

[0004] The existing technical disclosure number CN 210687309 U patent document provides a highly impact-resistant PVC double-wall corrugated pipe. When the corrugated pipe is impacted by an external force, the corrugated pipe transfers the force to the inner pipe, and then disperses the force through the support plate to prevent the corrugated pipe from being damaged. A flange is provided. When installing the support pipe and the inner pipe, the support pipe and the inner pipe are inserted into the interior of the corrugated pipe, and then the flange is sleeved on both ends of the inner pipe, so that the inner pipe is fixedly connected to the flange through an external thread, so that the flange is against both ends of the corrugated pipe, making it easy to fix the support pipe and the inner pipe inside the corrugated pipe.

[0005] However, the existing double-wall corrugated pipe is generally used to convey high-pressure water, which makes the inner wall of the double-wall corrugated pipe bear a large impact force. Long-term use can easily cause the double-wall corrugated pipe to rupture. In addition, the existing double-wall corrugated pipe makes a large noise when water flows, which is inconvenient to use. Utility Model Content

[0007] The purpose of the utility model is to provide an impact-resistant spiral corrugated pipe to solve the problem in the above background technology that the existing inner wall is subjected to a large impact force and the double-wall corrugated pipe is easily broken after long-term use.

[0008] (2) Technical solution

[0010] The anti-impact mechanism includes spiral corrugations, wave height, and wave pitch. Several spiral corrugations are fixedly installed on the surface of the corrugated pipe. The wave height is fixedly installed between the spiral corrugations and the corrugated pipe, and the wave pitch is fixedly installed between each spiral corrugation.

[0011] Preferably, the main body structure further includes a tube body and an outer protective shell, the tube body is fixedly installed on the bellows, and the outer surface of the bellows is fixedly installed with the outer protective shell.

[0012] Preferably, the main body structure further includes a fluid groove and a sealing ring. The fluid groove is fixedly installed inside the bellows, and the sealing ring is fixedly installed on the surface of the flange.

[0013] Preferably, the anti-impact mechanism further includes a flange and a sealing groove. The flange is fixedly installed between the bellows, and the sealing groove is fixedly installed on the surface of the flange.

[0014] Preferably, the anti-impact mechanism further includes a socket and a spigot, the socket is fixedly mounted on one end of the flange, and the spigot is fixedly mounted on the other end of the flange.

[0015] Preferably, the main body mechanism further includes bolts and nuts, and a plurality of bolts are fixedly mounted on the surface of the flange, and a plurality of nuts are fixedly mounted on the surface of the flange.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Effectively protect the conveyed medium. Its unique structure ensures the integrity of spiral corrugated pipes when subjected to external impacts, whether from collisions with surrounding objects or from natural disasters like earthquakes. The multi-layered pipe wall structure and spiral corrugation effectively disperse and absorb impact forces, preventing pipe rupture and ensuring leakage of the conveyed medium, thus ensuring safe and continuous conveying. Adaptable to complex operating conditions. In industrial production and municipal construction, pipelines may face various complex operating conditions, such as the crushing of heavy objects on construction sites and the vibration of underground pipelines from traffic. This impact-resistant spiral corrugated pipe can operate normally under these harsh conditions, reducing the frequency of repairs and replacements due to impacts and improving the stability of the entire pipeline system. Its impact resistance reduces the risk of damage, making the pipe less susceptible to accidental impacts during long-term use. Compared to ordinary pipes, it can better withstand external impacts, avoiding cracks and breakage, thereby significantly extending the pipe's service life. This not only reduces pipe replacement costs but also mitigates the indirect losses caused by production or service interruptions due to pipeline repairs. Reduce the aging rate. The outer protective shell of the spiral corrugated pipe can effectively resist the erosion of environmental factors such as ultraviolet rays and chemicals. At the same time, the impact-resistant structure reduces the damage to the internal structure caused by impact. These factors work together to slow down the aging rate of the pipeline and enable the pipeline to operate stably for a long time. Convenient connection and installation. Various connection structures make the spiral corrugated pipe more convenient during the installation process;

[0018] 2. Socket-and-spigot connections are simple to operate: simply insert the spigot into the socket and seal with a rubber sealing ring. Flange connections are more advantageous in applications requiring frequent disassembly and maintenance. Heat shrink sleeve connections provide excellent sealing and stability. These connection methods are easy for construction workers to operate, improving installation efficiency. They are also easy to maintain and repair. If local damage occurs during operation of the piping system, the structural features of impact-resistant spiral bellows make repairs relatively easy. For example, leaks in socket-and-spigot connections can be repaired simply by replacing the sealing ring. For minor external impact damage, the pipe's inherent impact resistance may require only a simple repair, eliminating the need for a major pipe replacement. They also reduce resource waste. Their long service life and low maintenance and replacement frequency reduce the amount of raw materials (such as plastic and steel) consumed by frequent pipe replacement, thus conserving resources. They also reduce the potential environmental pollution caused by the disposal of old pipes. They also reduce total costs. While impact-resistant spiral bellows may have a slightly higher initial investment cost, their superior impact resistance and low maintenance costs can significantly reduce overall lifecycle costs over the long term. This reduces production losses, repair costs, and the material and labor costs of replacing pipes caused by pipeline failures, resulting in excellent economic benefits. It has a wide range of applications, including building water supply and drainage, municipal wastewater disposal, industrial liquid transportation, agricultural irrigation, and more. Whether it's an internal building piping system or an open-air municipal engineering or industrial plant piping network, its impact resistance meets the needs of various scenarios, ensuring stable operation of the piping system.

[0032] Working principle: The innermost layer is a smooth inner pipe wall 102, whose main function is to ensure the smooth flow of the medium. It has good chemical stability, can resist the corrosion of the medium, and its smooth surface can reduce fluid resistance. The middle reinforcement layer 103, this reinforcement layer is a mesh structure woven from steel wire, glass fiber or other high-strength fiber materials, which can significantly improve the tensile and impact resistance of the pipeline. It is suitable for occasions with large external forces and has good corrosion resistance and insulation. The outer protective shell 105, the outer layer is a key part to protect the pipeline from the influence of the external environment. It is made of materials with good UV resistance and weather resistance. The outer layer has a certain texture structure. On the one hand, it can increase the wear resistance of the pipeline and prevent it from being scratched during installation or use; on the other hand, these structures can enhance the ring stiffness of the pipeline, making it not easy to deform when subjected to external pressure or impact. Spiral corrugation 201, this is the iconic structural feature of the spiral corrugated 201 pipe 101. The corrugations spiral around the circumference of the pipe, allowing them to adapt to a certain degree of bending and deformation without breaking. This makes them suitable for applications requiring flexible installation and effectively dissipates external forces. The corrugation dimensions include parameters such as wave height 202 and wave pitch 203. Wave height 202 determines the pipe's compressibility and elastic recovery. A higher wave height 202 means the pipe has more room to deform when subjected to external pressure and is better able to return to its original shape after the pressure subsides. Wave pitch 203 affects the overall strength and stability of the pipe. A properly designed wave pitch 203 can evenly distribute external forces across the corrugated structure when subjected to impact, preventing excessive localized stress. A flange connection involves installing flanges 204 at each end of the pipe and connecting them together using bolts 108. Flanges 204 have sealing grooves 205 for accommodating gaskets to ensure a tight seal. This connection is relatively secure and suitable for applications requiring frequent disassembly or requiring high connection strength. A socket-and-spigot connection consists of two parts: a socket 206 and a spigot 207. The socket 206 is the flared part at one end of the pipe, and the spigot 207 is the inserted part at the other end. During installation, the spigot 207 is inserted into the socket 206 and sealed with a rubber sealing ring 107. The rubber sealing ring 107 can ensure the sealing of the connection part and prevent the leakage of the medium. At the same time, it can also buffer the stress generated by the pipe connection part when it is impacted to a certain extent. The multi-layer pipe wall works together. When the spiral corrugated 201 pipe 101 is subjected to external impact, the outermost protective shell is the first to bear the impact. The middle reinforcement layer 103 plays a key role in impact resistance. For the spiral corrugated 201 pipe 101 reinforced with steel wire, the wire mesh can effectively disperse the impact force. When an impact occurs, the impact force acts on the pipe. The wire mesh, through its own high strength and toughness, diffuses the concentrated impact force to the surroundings, like a solid skeleton, preventing local damage to the pipe, and also providing additional corrosion resistance and insulation properties.The smooth pipe wall of the innermost layer is mainly to ensure the normal transportation of the medium, but it also plays a certain supporting role in the impact resistance process. It is tightly combined with the middle reinforcement layer 103 and the outer layer to maintain the overall structural integrity of the pipeline, ensuring that no rupture will occur when impacted, resulting in medium leakage. The buffering and dispersing effect of the corrugation, and the spiral corrugated structure are important factors in impact resistance. When the pipeline is subjected to external impact force, the corrugation can undergo elastic deformation. For example, semicircular corrugations will be compressed or stretched, and the sides of the trapezoidal corrugations will produce a certain degree of bending. This deformation process can absorb and buffer the impact force, converting the instantaneous strong impact force into the elastic potential energy of the corrugation. The shape and size design of the corrugation enables the impact force to be effectively dispersed in the circumferential and axial directions of the pipeline. Reasonable wave height 202 and wave distance 203 allow each corrugation to share part of the impact force, avoiding excessive local force. For example, when a pipe is impacted from the side, the impact force is transmitted along the spiral direction of the corrugations and shared by multiple corrugations, much like distributing a concentrated force across multiple support points. This reduces the pressure on each component and improves the pipe's impact resistance. In a socket-and-socket connection, the rubber sealing ring 107 is a key component for impact resistance. When the pipe is impacted, the connection is susceptible to displacement and deformation. Due to its elasticity, the rubber sealing ring 107 can deform to a certain extent as the pipe deforms, maintaining a constant seal. Furthermore, the sealing ring 107 buffers the impact stress at the connection, preventing the pipe interface from loosening or being damaged by the impact. The flange connection ensures stability and impact resistance. The flange connection securely fastens the two flanges 204 together using bolts 108. When the pipe is impacted, the preload of the bolts 108 counteracts the tendency for the impact force to separate. Furthermore, the sealing gasket between the flanges 204 prevents leakage and, to a certain extent, mitigates the effects of the impact force on the connection. Moreover, since the flange connection is relatively firm, the impact stress can be effectively dispersed to the entire connection structure and adjacent pipeline parts in the pipeline system, ensuring the stability of the connection.

[0033] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
