[0001] The utility model relates to the technical field of water supply pipes, in particular to a pressure-resistant PE water supply pipe. Background Art

[0002] A water supply pipe is a device used for water transportation, which is generally laid underground or in an exposed environment. Among them, a PE water supply pipe is a polyethylene plastic pipe with excellent properties and can withstand most domestic and industrial chemicals. Therefore, it is widely used in highways, railways, greening, and various water supply and drainage fields. The application number CN201811196045.5 is retrieved, which is a PE water supply pipe. This invention can not only meet the needs of water transportation, but also has the advantages of low temperature resistance, low tensile strength, and wear resistance. In addition, the pipe bodies can be connected by snap-on connection, which not only improves the installation efficiency and reduces the difficulty of assembly, but also further effectively improves the strength of both ends of the pipe body and is not easy to damage.

[0003] Similar to the above-mentioned PE water supply pipe: although the clamping groove and the clamping part cooperate to enable the pipe bodies to be connected by clamping, thereby reducing the difficulty of assembly, firstly, the current PE water supply pipe often has poor pressure resistance due to material limitations. Secondly, the existing PE water supply pipe often has no buffer mechanism, and is easily broken by large pressure shocks, which greatly reduces the service life of the PE water supply pipe.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a pressure-resistant PE water supply pipe is proposed to achieve a more practical purpose. Utility Model Content

[0005] The purpose of the utility model is to provide a pressure-resistant PE water supply pipe to solve the problem that the above-mentioned PE water supply pipe proposed in the above-mentioned background technology firstly has poor pressure resistance due to material limitations at present, and secondly, the existing PE water supply pipe is often not provided with a buffer mechanism, which is easily caused to break when subjected to large pressure shocks, greatly reducing the service life of the PE water supply pipe.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure-resistant PE water supply pipe, comprising a water supply pipe body, an outer anti-corrosion layer and a nano antibacterial layer, the outer wall of the water pipe body is provided with an outer anti-corrosion layer, the nano antibacterial layer is arranged around the inner wall of the water pipe body, the water pipe body comprises a PE pipe inner layer and a PE pipe outer layer, and the outer wall of the PE pipe inner layer is provided with a PE pipe outer layer.

[0008] Furthermore, a buffer mechanism is arranged in the middle of the inner layer of the PE pipe and the outer layer of the PE pipe, and the buffer mechanism includes a No. 1 fixing cylinder, a No. 2 fixing cylinder, a connecting rod, a limiting groove, a supporting spring and a damping block.

[0009] Furthermore, a No. 2 fixing cylinder is arranged on the top of the No. 1 fixing cylinder, and the No. 2 fixing cylinder is arranged opposite to the No. 1 fixing cylinder. A connecting rod is arranged on the side of the No. 1 fixing cylinder opposite to the No. 2 fixing cylinder, and a limiting groove is arranged on one side of the connecting rod, and a supporting spring is connected to the inner wall of the limiting groove.

[0010] Furthermore, the two groups of connecting rods are respectively embedded in opposite limiting grooves, the side of the supporting spring away from the inner wall of the limiting groove is in contact with the connecting rod, and damping blocks are provided on opposite sides of the two groups of connecting rods, and the two groups of damping blocks are in contact with each other.

[0011] Furthermore, a connecting sleeve is provided at one end of the water supply pipe body, and a plug-in groove is provided at one end of the water supply pipe body away from the connecting sleeve. The connecting sleeve matches the plug-in groove, and the inner wall of the plug-in groove is arranged with a molten embedding groove. The material of the nano antibacterial layer is composed of nano-scale silver particles or silver ions.

[0012] Compared with the prior art, the utility model has the following beneficial effects: a pressure-resistant PE water supply pipe adopts reinforcing ribs and support rings, which not only enhances the pressure resistance of the pipe, but also improves its overall stability, prevents it from being deformed under the action of external forces, and adopts a buffer mechanism to play a buffering role when subjected to pressure shock, thereby preventing the water supply pipe body from being broken when subjected to large pressure shock. The specific contents are as follows:

[0013] The middle of the inner layer and the outer layer of the PE pipe are arranged with reinforcing ribs, which not only enhance the pressure resistance of the pipe, but also improve its overall stability. The inner wall of the nano antibacterial layer is arranged with supporting rings, which can further reinforce the pipe to prevent it from deforming under the action of external force. The middle of the inner layer and the outer layer of the PE pipe is arranged with a buffer mechanism, which plays a role in buffering and shock resistance. It plays a buffering role when subjected to pressure shock, so as to avoid the PE water supply pipe from breaking when the water supply pipe body is subjected to greater pressure shock. The buffer mechanism includes a No. 1 fixed cylinder, a No. 2 fixed cylinder, Connecting rod, limit groove, support spring and damping block. When the water supply pipe body is squeezed or impacted, the outer layer of the PE pipe shrinks inward, driving the No. 2 fixed cylinder to move toward the direction of the No. 1 fixed cylinder. The connecting rod on one side of the No. 2 fixed cylinder translates into the limit groove. The movement of the connecting rod pushes the support spring to shrink under pressure, thereby playing a role in buffering and shock absorption.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: a pressure-resistant PE water supply pipe, comprising a water supply pipe body 1, an outer anti-corrosion layer 2 and a nano antibacterial layer 3. The outer wall of the water pipe body 1 is provided with the outer anti-corrosion layer 2, and the outer anti-corrosion layer 2 can effectively protect the pipe from being invaded by the external environment and prolong the service life of the pipe. The nano antibacterial layer 3 is arranged around the inner wall of the water pipe body 1. The nano antibacterial layer 3 is mainly composed of nano-scale silver particles or silver ions. This material has excellent antibacterial properties and can effectively inhibit the growth of bacteria to ensure the quality of water supply. At the same time, the nano antibacterial layer 3 also has a certain self-cleaning function, which can reduce the frequency and cost of pipeline maintenance. The water pipe body 1 comprises a PE pipe inner layer 4 and a PE pipe outer layer 5. The outer wall of the PE pipe inner layer 4 is provided with a PE pipe outer layer 5. The double-layer design of the PE pipe inner layer 4 and the PE pipe outer layer 5 makes the PE pipe outer layer 5 squeeze inward into the cavity between the two when the water supply pipe is squeezed, thereby avoiding the PE pipe inner layer 4 from being squeezed, thereby improving the pressure resistance of the pipe.

[0021] Reinforcing ribs 6 are arranged in the middle of the PE pipe inner layer 4 and the PE pipe outer layer 5. The reinforcing ribs 6 not only enhance the compressive performance of the pipe, but also improve its overall stability. The inner wall of the nano antibacterial layer 3 is arranged with a supporting ring 7, which can further reinforce the pipe to prevent it from being deformed under the action of external force.

[0022] A buffer mechanism 8 is arranged in the middle of the PE pipe inner layer 4 and the PE pipe outer layer 5. The buffer mechanism 8 plays a role in buffering and shock resistance. It plays a buffering role when subjected to pressure shock to prevent the water supply pipe body 1 from breaking when subjected to large pressure shock. The buffer mechanism 8 includes a No. 1 fixed cylinder 9, a No. 2 fixed cylinder 10, a connecting rod 11, a limit groove 12, a support spring 13 and a damping block 14.

[0023] A No. 2 fixing cylinder 10 is arranged on the top of the No. 1 fixing cylinder 9, and the No. 2 fixing cylinder 10 is arranged opposite to the No. 1 fixing cylinder 9. A connecting rod 11 is arranged on the side of the No. 1 fixing cylinder 9 opposite to the No. 2 fixing cylinder 10. The connecting rod 11 plays a contraction role. A limiting groove 12 is arranged on one side of the connecting rod 11. The limiting groove 12 plays the role of limiting the connecting rod 11. A supporting spring 13 is connected to the inner wall of the limiting groove 12. The supporting spring 13 plays a shock-absorbing role and rebounds after being compressed and contracted.

[0024] The two groups of connecting rods 11 are respectively embedded in the relative limiting grooves 12, and the side of the supporting spring 13 away from the inner wall of the limiting groove 12 is abutted against the connecting rod 11. Damping blocks 14 are provided on the opposite sides of the two groups of connecting rods 11, and the two groups of damping blocks 14 are abutted against each other. When the water supply pipe body 1 is squeezed or impacted, the outer layer 5 of the PE pipe shrinks inward, driving the No. 2 fixed cylinder 10 to move toward the direction of the No. 1 fixed cylinder 9, and the connecting rod 11 on the side of the No. 2 fixed cylinder 10 translates into the limiting groove 12. The movement of the connecting rod 11 pushes the supporting spring 13 to shrink under pressure, thereby playing a role in buffering and shock absorption. The friction force generated by the mutual movement of the two groups of damping blocks 14 plays a certain damping role, thereby avoiding the impact force generated by the rebound of the supporting spring 13 after absorbing shock, thereby realizing the buffering effect on the water supply pipe body 1, and avoiding the PE water supply pipe from breaking when the water supply pipe body 1 is subjected to greater pressure or shock.

[0025] A connecting sleeve 15 is provided at one end of the water supply pipe body 1, and a plug-in groove 16 is provided at the end of the water supply pipe body 1 away from the connecting sleeve 15. The connecting sleeve 15 matches the plug-in groove 16. The plug-in groove 16 can be extruded into the connecting sleeve 15 after hot melting. The inner wall of the plug-in groove 16 is arranged with molten embedding grooves 17. This structure can ensure that the pipeline forms a good seal when connected to prevent water leakage. The material of the nano antibacterial layer 3 is composed of nano-scale silver particles or silver ions.

[0026] Working principle: When using a pressure-resistant PE water supply pipe, first connect the water supply pipe body 1 to the designated pipe. The outer anti-corrosion layer 2 can effectively protect the pipe from the external environment and extend the service life of the pipe. The nano antibacterial layer 3 can effectively inhibit the growth of bacteria and ensure the quality of water supply. At the same time, the nano antibacterial layer 3 also has a certain self-cleaning function, which can reduce the frequency and cost of pipeline maintenance. The reinforcing ribs 6 not only enhance the pressure resistance of the pipe, but also improve its overall stability. The inner wall of the nano antibacterial layer 3 is arranged with support rings 7, which can further reinforce the pipe to prevent it from deformation under the action of external force. When the water supply pipe body 1 is squeezed or impacted, the outer layer 5 of the PE pipe shrinks inward, driving the second fixed The cylinder 10 moves toward the direction of the No. 1 fixed cylinder 9, and the connecting rod 11 on the side of the No. 2 fixed cylinder 10 translates into the limit groove 12. The movement of the connecting rod 11 pushes the support spring 13 to be compressed and contracted, thereby playing a role of buffering and shock absorption. The friction force generated by the mutual movement of the two groups of damping blocks 14 plays a certain damping role, thereby avoiding the impact force generated by the rebound of the support spring 13 after shock absorption, thereby achieving a buffering effect on the water supply pipe body 1, and avoiding the PE water supply pipe from breaking when the water supply pipe body 1 is subjected to greater pressure or shock. The plug-in groove 16 can be hot-melted and squeezed into the connecting sleeve 15, and the inner wall of the plug-in groove 16 is arranged with a molten embedding groove 17. This structure can ensure that the pipeline forms a good seal when connected to prevent water leakage.
