Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline technical field, concretely relates to an impact resistance metal pipeline. BACKGROUND

[0002] A pipeline is a tubular structure used for transporting fluids (liquids, gases, or slurries) and is widely used in various industries, construction, and infrastructure. A pipeline system usually consists of a series of pipes, fittings (such as flanges, clamps), valves, pumps, and other auxiliary equipment.

[0003] In the application number 202020428617.4 discloses an impact resistance pipeline, "including a pipe body and a buffer sheet sleeved on the outside of the pipe body, the two sides of the buffer sheet are connected by a connecting strip, the buffer sheet is used for buffering the impact force from the outside, when the buffer sheet is subjected to the impact force from the outside, the elastic deformation of the buffer protrusion occurs at the same time, the air in the buffer protrusion cavity is compressed and consumes part of the impact force, thereby improving the buffering capacity of the buffer protrusion", the above-mentioned can enhance the impact resistance of the outer wall by setting the buffer sheet and the buffer protrusion on the outside of the pipeline, but the protection of the inner wall of the pipeline is still insufficient, especially in the case of rapid start-stop of water flow or improper operation of the valve, water hammer effect is easy to occur, water hammer will cause the inner wall to bear instantaneous high pressure impact, repeated impact will cause material fatigue, cracks or leakage, and shorten the service life of the pipeline. UTILITY MODEL CONTENT

[0004] The utility model aims at providing an impact resistance metal pipeline to solve the problem of water hammer effect caused by rapid start-stop of water flow or improper operation of the valve, leading to instantaneous high pressure impact on the inner wall, repeated impact causing material fatigue, cracks or leakage, and thus shortening the service life of the pipeline.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an impact resistance metal pipeline, comprising: a first pipeline, both ends of the first pipeline are provided with a second pipeline, a hollow pipe is arranged in the second pipeline, a plurality of baffles are arranged around the outer wall of the hollow pipe, a fixing rod is inserted into the hollow pipe, a fixing column is arranged on both sides of the inner wall of the second pipeline, and both ends of the fixing rod are connected with the fixing columns on both sides respectively, and a rolling assembly is arranged between the hollow pipe and the fixing column.

[0006] Preferably, the rolling assembly comprises a rolling groove and a ball, the rolling groove is arranged at one end of the fixing column close to the hollow pipe, the ball is arranged in the rolling groove, and the hollow pipe is in contact with the ball;

[0007] A plurality of guide grooves are formed on the outer wall of the baffle, and a plurality of mounting plates are connected to the outer wall of the hollow tube. The first bolts are connected between the mounting plates and the baffle, which are designed to facilitate the quick disassembly and assembly operation between the mounting plates and the baffle. Through simple tightening and loosening operation, users can easily complete the connection and separation of the mounting plate and the baffle without complex tools or steps. This design not only improves the efficiency of installation and disassembly, but also reduces the maintenance time and labor cost. In addition, the first bolt is made of high-strength material to ensure its stable connection performance during frequent disassembly and assembly, and is not easy to loosen or damage, thereby ensuring the reliability and durability of the connection between the mounting plate and the baffle.

[0008] Through the above technical solutions:

[0009] In use, the first pipeline is designed as a curved structure, and the second pipeline is respectively installed at both ends of the first pipeline to form a complete fluid channel. When the water flow enters or leaves the first pipeline, the water flow will be transmitted through the second pipeline. During the transmission of the water flow, the water flow first impacts the baffle, which guides the water flow through the guide grooves to concentrate the impact on a specific area of the baffle, thereby effectively controlling the flow direction and impact force of the water flow;

[0010] The baffle is connected with the fixed rod through the hollow tube and can rotate freely outside the fixed rod. During rotation, the balls roll in the rolling grooves, which cleverly converts the sliding friction between the hollow tube and the fixed column into rolling friction. The reduction of rolling friction not only reduces the friction, but also significantly improves the rotation efficiency of the hollow tube, so that it can more smoothly cope with the impact and pressure changes of the water flow;

[0011] In order to ensure the stability and safety of the hollow tube, the fixed columns on both sides play a limiting role to prevent the hollow tube from colliding with the inner wall of the second pipeline during rotation. This limiting design not only enhances the safety of the equipment, but also effectively prevents wear and damage caused by collision. When the water flow enters the second pipeline through the first pipeline, if the water volume exceeds the carrying capacity of the second pipeline, the excess water flow will be smoothly discharged through the gap between the baffle and the second pipeline. This design not only effectively prevents the excessive accumulation and excessive pressure of the water flow, but also avoids potential damage to the pipeline system caused by water overflow. The gap between the baffle and the second pipeline is precisely designed to ensure that the excess water flow can be smoothly discharged while maintaining the sealing and overall strength of the pipeline system.

[0012] In summary, the baffle can generate resistance to the water flow when it rotates under the impact of the water flow. This resistance generated by the baffle plays a crucial role in the pipeline system. First, the counterforce generated by the baffle under the impact of the water flow can effectively slow down the water flow speed, reduce the kinetic energy of the water flow, and thus reduce the direct impact force of the water flow on the inner wall of the pipeline. Through the action of this resistance, the impact force of the water flow is dispersed and absorbed, reducing the instantaneous high-pressure impact of the water flow on the pipeline. Second, the design of the baffle not only slows down the water flow speed, but also effectively suppresses the generation of water hammer effect. Water hammer effect is usually caused by the sharp change of water flow speed, and the resistance of the baffle can smooth the change curve of the water flow, reduce the fluctuation amplitude of the water flow speed, and thus significantly reduce the strength and frequency of the water hammer effect. This design ensures that the pipeline system can still maintain stable operation state when facing instantaneous high pressure and rapid flow change. In addition, the baffle further enhances its control ability over the water flow through its unique geometric shape and material characteristics. The surface design of the baffle can guide the water flow along a specific path, reducing the formation of turbulent flow and vortex, thereby reducing the local impact of the water flow on the inner wall of the pipeline. This optimized water flow control not only improves the impact resistance performance of the pipeline, but also prolongs the service life of the pipeline. Through these comprehensive effects, the resistance mechanism of the baffle effectively improves the impact resistance performance of the inner wall of the first pipeline and the second pipeline. Under this design, the pipeline system can better cope with water flow impact and pressure fluctuations under various complex working conditions, ensuring its safety and reliability in long-term operation.

[0013] The connecting clamp is provided with a protective sleeve on the outer wall, the protective sleeve is in a wave shape, the outer wall of the second pipeline is provided with a first reinforcing clamp, the outer wall of the first pipeline is provided with a second reinforcing clamp, the outer wall of the first reinforcing clamp is provided with a first reinforcing plate, the outer wall of the second reinforcing clamp is provided with a second reinforcing plate, and a connecting assembly is arranged between the first reinforcing plate and the second reinforcing plate.

[0014] Preferably, the connecting assembly comprises a threaded groove, a reinforcing rod and an external thread, the threaded groove is arranged on the first reinforcing plate, the reinforcing rod passes through the second reinforcing plate, the external thread is arranged on the outer wall of the reinforcing rod, and the threaded groove and the external thread are matched;

[0015] The third reinforcing plate is arranged outside the connecting clamp, and the reinforcing rod and the third reinforcing plate are connected through threads;

[0016] The connecting clamp, the first reinforcing clamp and the second reinforcing clamp are fixed by the second bolts.

[0017] Through the above technical solutions:

[0018] In use, the second bolt serves as a key connecting component to firmly secure the connecting clamp at the connection site of the first pipe and the second pipe. With precise mechanical connection, the second bolt ensures that the connecting clamp provides stable support and reliable sealing performance at the pipe connection;

[0019] The wave-shaped protective sleeve is tightly fitted on the outer wall of the connecting clamp. The protective sleeve not only effectively disperses various impact forces borne by the connecting clamp during pipe operation through its wave-shaped structure, but also plays a buffering and damping role, thereby significantly reducing stress concentration at the connection site and protecting the connection site of the first pipe and the second pipe from damage;

[0020] The first reinforcing clamp is specially designed to be installed on the outer wall of the second pipe, while the second reinforcing clamp is installed on the outer wall of the first pipe. Through precise installation process, the reinforcing rod is cleverly threaded through the second reinforcing plate and screwed into place. At this time, the external threads of the reinforcing rod tightly match the threaded grooves, forming a reliable mechanical connection. This design ensures the stable connection between the first reinforcing plate and the second reinforcing plate, thereby forming a solid overall structure;

[0021] The reinforcing rod is stably connected with the connecting clamp through the third reinforcing plate. As an intermediate connecting piece, the third reinforcing plate ensures the close fit between the reinforcing rod and the connecting clamp, thereby forming an effective limiting action on the connecting clamp. This structural design can effectively prevent the connecting clamp from displacement or deviation during pipe operation, ensuring the stability and reliability of the pipe connection;

[0022] In this way, the first reinforcing clamp and the second reinforcing clamp form a mutual force of interaction. This mutual force is evenly distributed on the first pipe and the second pipe, not only enhancing the strength and stability of the pipe connection, but also effectively preventing the pipe from falling off or loosening under high pressure or severe vibration.

[0023] In addition, the design also fully considers the thermal expansion and contraction effect of the pipe under different working conditions. Through precise mechanical fit and reasonable material selection, it ensures that the pipe system can maintain good sealing performance and connection strength under various environmental conditions.

DETAILED DESCRIPTION

[0034] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0035] Please refer to Figures 1-5As shown, the utility model provides the following technical solutions: an impact-resistant metal pipe, comprising: a first pipe 1, a second pipe 2 is installed at both ends of the first pipe 1, a horizontal hollow pipe 3 is provided in the second pipe 2, a plurality of baffles 4 are installed around the outer wall of the hollow pipe 3, a fixing rod 6 is inserted in the hollow pipe 3, fixing columns 5 are installed on both sides of the inner wall of the second pipe 2, and the two ends of the fixing rod 6 are respectively connected to the fixing columns 5 on both sides, and a rolling component is provided between the hollow pipe 3 and the fixing column 5.

[0036] Furthermore, the rolling assembly includes a rolling groove 501 and a ball 502. The rolling groove 501 is provided at one end of the fixing column 5 close to the hollow tube 3. The ball 502 is installed in the rolling groove 501, and the hollow tube 3 is in contact with the ball 502.

[0037] The outer wall of the baffle 4 is provided with multiple flow guide grooves 401. Multiple mounting plates 7 are connected to the outer wall of the hollow tube 3. A first bolt 701 is connected between the mounting plates 7 and the baffle 4. The first bolt 701 is designed to facilitate quick assembly and disassembly between the mounting plates 7 and the baffle 4. Through simple tightening and loosening operations, users can easily connect and disconnect the mounting plates 7 from the baffle 4 without the need for complex tools or procedures. This design not only improves installation and disassembly efficiency but also reduces maintenance time and labor costs. Furthermore, the first bolt 701 is made of high-strength material, ensuring a stable connection during frequent assembly and disassembly, and resists loosening or damage, thereby ensuring a reliable and durable connection between the mounting plates 7 and the baffle 4.

[0038] Through the above technical solution:

[0039] During operation, the first pipe 1 is designed as a curved structure, and the second pipes 2 are installed at both ends of the first pipe 1, forming a complete fluid channel. When water enters or leaves the first pipe 1, it is transported through the second pipe 2. During this process, the water first strikes the baffle 4. The baffle 4 guides the water flow through the guide grooves 401, concentrating it on a specific area of ​​the baffle 4, effectively controlling the flow direction and impact force of the water.

[0040] The baffle 4 is connected to the fixed rod 6 via the hollow tube 3 and rotates freely outside the fixed rod 6. During rotation, the balls 502 roll within the rolling grooves 501. This design cleverly converts the sliding friction between the hollow tube 3 and the fixed rod 5 into rolling friction. This reduction in rolling friction not only reduces friction but also significantly improves the rotation efficiency of the hollow tube 3, allowing it to more smoothly respond to water flow shocks and pressure changes.

[0041] To ensure the stability and safety of the hollow tube 3, the fixed columns 5 on both sides play a limiting role, preventing the hollow tube 3 from colliding with the inner wall of the second pipeline 2 during rotation. This limiting design not only enhances the safety of the equipment, but also effectively prevents wear and damage caused by collisions. When the water flow enters the second pipeline 2 through the first pipeline 1, if the water volume exceeds the carrying capacity of the second pipeline 2, the excess water flow will smoothly drain through the gap between the baffle 4 and the second pipeline 2. This design not only effectively prevents excessive accumulation of water flow and excessive pressure, but also avoids potential damage to the pipeline system caused by water overflow. The gap between the baffle 4 and the second pipeline 2 is precisely designed to ensure that excess water flow can be smoothly drained while maintaining the sealing and overall strength of the pipeline system.

[0042] In summary, the baffle 4 can generate a certain resistance to the incoming and outgoing water flow when it rotates under the impact of the water flow. This resistance generated by the baffle 4 plays a crucial role in the pipeline system. First, the counterforce generated by the baffle 4 under the impact of the water flow can effectively slow down the water flow speed, reducing the kinetic energy of the water flow, and thus reducing the direct impact force of the water flow on the inner wall of the pipeline. Through the action of this resistance, the impact force of the water flow is dispersed and absorbed, reducing the instantaneous high-pressure impact of the water flow on the pipeline. Second, the design of the baffle 4 not only slows down the water flow speed, but also effectively suppresses the generation of water hammer effect. Water hammer effect is usually caused by the sharp change of water flow speed, and the resistance of the baffle 4 can smooth the change curve of the water flow, reducing the fluctuation amplitude of the water flow speed, thereby significantly reducing the strength and frequency of the water hammer effect. This design ensures that the pipeline system can still maintain stable operation when facing instantaneous high pressure and rapid flow changes. In addition, the baffle 4 further enhances its control ability over the water flow through its unique geometric shape and material properties. The surface design of the baffle 4 can guide the water flow along a specific path, reducing the formation of turbulent and vortex flow, thereby reducing the local impact of the water flow on the inner wall of the pipeline. This optimized water flow control not only improves the impact resistance of the pipeline, but also prolongs the service life of the pipeline. Through these comprehensive effects, the resistance mechanism of the baffle 4 effectively improves the impact resistance of the inner walls of the first pipeline 1 and the second pipeline 2. Under this design, the pipeline system can better cope with water flow impact and pressure fluctuations under various complex working conditions, ensuring its safety and reliability in long-term operation.

With precise mechanical connection, the second bolt ensures that the connecting clamp 8 provides stable support and reliable sealing performance at the pipe connection part;

[0049] The protective sleeve 14 in a wavy shape is tightly sleeved on the outer wall of the connecting clamp 8. The protective sleeve 14 not only effectively disperses various impact forces borne by the connecting clamp 8 during pipe operation through its wavy structure, but also plays a role in buffering and shock absorption, thereby greatly reducing stress concentration at the connection part and protecting the connection part of the first pipe 1 and the second pipe 2 from damage;

[0050] The first reinforcing clamp 9 is specially designed to be installed on the outer wall of the second pipe 2, and the second reinforcing clamp 10 is installed on the outer wall of the first pipe 1.

This design ensures the stable connection between the first reinforcing plate 11 and the second reinforcing plate 12, thereby forming a solid overall structure;

[0051] The reinforcing rod 13 is stably connected with the connecting clamp 8 through a third reinforcing plate 15. The third reinforcing plate 15 serves as an intermediate connecting piece, ensuring the close fit between the reinforcing rod 13 and the connecting clamp 8, thereby forming an effective limiting action on the connecting clamp 8. This structural design can effectively prevent the connecting clamp 8 from being displaced or deviated during the operation of the pipeline, ensuring the stability and reliability of the pipeline connection;

[0052] In this way, the first reinforcing clamp 9 and the second reinforcing clamp 10 form a mutual interaction of opposite forces. This opposite force is evenly distributed on the first pipeline 1 and the second pipeline 2, not only enhancing the strength and stability of the pipeline connection, but also effectively preventing the pipeline from falling off or loosening under high pressure or severe vibration.
