Description

Technical Field

[0001] This utility model relates to the field of kraft pipe technology, specifically a high-strength three-layer co-extruded HDPE kraft pipe. Background Technology

[0002] Krah pipe, also known as hot-wound high-density polyethylene (HDPE) spiral wound structured wall pipe, is a special structural wall pipe with high resistance to external pressure. It is made primarily from high-density polyethylene resin using a hot-wound process and supported by a single-walled polypropylene (PP) corrugated pipe. This type of pipe offers numerous advantages and is widely used in various fields.

[0003] According to Chinese Patent CN216279815U, a novel high-strength corrugated pipe includes a main body and a telescopic support rod. Several sets of reinforcing ribs are evenly installed on one side of the inner surface of the main body. A metal mesh is fixedly installed at one end of each reinforcing rib, and a shock-absorbing pad is wrapped around the outer periphery of the metal mesh. A slide rail is fixedly arranged around the inside of the shock-absorbing pad. This invention utilizes a telescopic support rod, an inner ring, an auxiliary ring, and a shock-absorbing spring. In actual use, when water flows into the device, the varying flow rates cause the auxiliary ring and inner ring to slide to a certain extent. This allows the area formed between the auxiliary ring and the inner ring to accommodate different amounts of water flow, preventing excessive water flow from causing pipe wall rupture and extending service life. Furthermore, during adjustment, the telescopic support rod supports the inner wall of the pipe, and the shock-absorbing spring alleviates pressure, reducing damage. It has the advantages of good pressure resistance and long service life.

[0004] In practical use, the internal pressure of the pipeline changes with the flow rate and velocity of the transported medium. When the flow rate suddenly increases or the flow velocity rises sharply, the internal pressure of the pipeline will increase abruptly. The aforementioned devices rely solely on their fixed structural strength to withstand the pressure, lacking an adaptive and reinforcing structure. When the internal pressure suddenly increases and exceeds its withstand limit, it can lead to pipeline leakage or rupture. Therefore, we provide a high-strength three-layer co-extruded HDPE Krah pipe. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength three-layer co-extruded HDPE kraft pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength three-layer co-extruded HDPE Krah pipe, comprising: a Krah pipe body;

[0007] Reinforcing ribs fixedly connected to the outer wall of the kraft tube body;

[0008] A connecting pipe fixedly connected to the side of the kraft tube body;

[0009] A protective layer fixedly connected to the inner wall of the kraft tube body;

[0010] And an operating component disposed on the surface of the connecting pipe; the operating component includes a connecting portion disposed on the side of the connecting pipe, the connecting portion being connected to a reinforcing portion.

[0011] Preferably, the connecting part includes a mating groove that snaps onto the outer wall of the connecting pipe. The mating groove is opened on the side of the connecting pipe. A rubber ring is fixedly connected to the inner surface of the mating groove. An elastic sheet is correspondingly provided on the inner wall of the rubber ring. The bottom end of the elastic sheet is fixedly connected to the outer wall of the connecting pipe. A connecting rod is fixedly connected to the bottom of the elastic sheet. The bottom end of the connecting rod penetrates the inner surface of the through hole and extends to be inserted into the inner surface of the connecting groove. The through hole is opened on the outer wall of the connecting pipe, and the connecting groove is opened on the inner surface of the mating groove.

[0012] Preferably, the reinforcing part includes an annular rod fixedly connected to the inner wall of the docking block tube. An annular groove is formed on the inner wall of the annular rod. A cross rod is slidably connected to the inner surface of the annular groove. A shaft is fixedly passed through the side of the cross rod. A bottom rod is fixedly connected to the outer wall of the shaft. A groove is formed on the side of the bottom rod away from the shaft. An extension rod is fixedly connected to the inner surface of the groove by an adjusting spring. A reinforcing plate is fixedly connected to the outer end of the extension rod.

[0013] Preferably, the inner wall of the rubber ring and the outer wall of the elastic sheet are abutted together, and the rubber ring plays a certain limiting role in the elastic sheet, allowing the elastic sheet to be kept in a suitable position.

[0014] Preferably, the position of the through hole corresponds to the position of the connecting groove, and the two are connected, so that the connecting rod can pass smoothly through the through hole and be inserted into the connecting groove, so that a stable connection is formed between the connecting pipe and the connecting tube.

[0015] Preferably, the bottom end of the extension rod is slidably inserted into the inner surface of the groove of the base rod, so that the position of the reinforcing plate can be adjusted according to actual needs.

[0016] Preferably, the reinforcing plate is arc-shaped, and its outer wall is in contact with the connecting pipe and the inner wall of the protective layer. The reinforcing plate can increase the strength of the connecting pipe and the protective layer, disperse the internal fluid pressure and external pressure of the Krah pipe body, prevent the Krah pipe body from deforming or breaking under pressure, and further improve the stability and overall strength of the Krah pipe body connection.

[0017] Compared with the prior art, this utility model provides a high-strength three-layer co-extruded HDPE kraft pipe, which has the following beneficial effects:

[0018] 1. This high-strength three-layer co-extruded HDPE kraft pipe has connecting pipes on both sides inserted into the inner surfaces of the mating grooves on both sides of the connecting pipe, achieving the initial installation of the two kraft pipe bodies. When the mating groove of the connecting pipe is connected to the connecting pipe, the rubber ring squeezes the elastic sheet, causing the elastic sheet to deform under pressure, and driving the connecting rod to pass through the through hole and extend into the inner surface of the connecting groove, making the connection between the connecting pipe and the connecting pipe more secure, preventing loosening or separation due to external forces during use, ensuring the overall stability of the kraft pipe body, and the elasticity of the elastic sheet can buffer the impact force during the docking process to a certain extent, avoiding damage to the connection part due to external impact.

[0019] 2. This high-strength three-layer co-extruded HDPE Krah pipe features an extension rod that extends outward under the action of an adjusting spring when the internal pressure increases. The reinforcing plate then makes close contact with the connecting pipe and the inner wall of the protective layer, enhancing the pressure resistance of the connection. When the pressure decreases, the adjusting spring retracts, and the extension rod returns to its initial position. Simultaneously, the arc-shaped design of the reinforcing plate perfectly fits the connecting pipe and the inner wall of the protective layer, evenly distributing pressure and reinforcing the connection from multiple angles. During the installation of the Krah pipe, even if there is a certain angular deviation or positional error between the connecting pipe and the connecting tube, fine adjustments are made by sliding the cross rod within the annular groove, ensuring that the reinforcing plate accurately contacts the connecting pipe and the inner wall of the protective layer, achieving effective reinforcement.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example 1: The high-strength three-layer co-extruded HDPE kraft pipe provided by this utility model, such as... Figures 1 to 5 As shown: A high-strength three-layer co-extruded HDPE Krah pipe, comprising: Krah pipe body 1;

[0029] Reinforcing rib 2 is fixedly connected to the outer wall of the carbide tube body 1;

[0030] A connecting pipe 3 is fixedly connected to the side of the body 1 of the kraft tube;

[0031] A protective layer 4 is fixedly connected to the inner wall of the kra tube body 1;

[0032] And an operating component 5 disposed on the surface of the connecting pipe 3; the operating component 5 includes a connecting part 51 disposed on the side of the connecting pipe, and a reinforcing part 52 is connected to the connecting part 51.

[0033] The connecting part 51 includes a mating groove 512 that snaps onto the outer wall of the connecting pipe 3. The mating groove 512 is opened on the side of the connecting pipe 511. A rubber ring 513 is fixedly connected to the inner surface of the mating groove 512. An elastic piece 514 is correspondingly provided on the inner wall of the rubber ring 513. The bottom end of the elastic piece 514 is fixedly connected to the outer wall of the connecting pipe 3. A connecting rod 515 is fixedly connected to the bottom of the elastic piece 514. The bottom end of the connecting rod 515 penetrates the inner surface of the through hole 516 and extends to be inserted into the inner surface of the connecting groove 517. The through hole 516 is opened on the outer wall of the connecting pipe 3, and the connecting groove 517 is opened on the inner surface of the mating groove 512.

[0034] In this embodiment, the inner wall of the rubber ring 513 and the outer wall of the elastic sheet 514 are in contact, and the rubber ring 513 plays a certain limiting role on the elastic sheet 514, so that the elastic sheet 514 can be kept in a suitable position.

[0035] Furthermore, the position of the through hole 516 corresponds to the position of the connecting groove 517, and the two are connected, so that the connecting rod 515 can pass smoothly through the through hole 516 and be inserted into the connecting groove 517, so that a stable connection is formed between the connecting pipe 3 and the connecting tube 511.

[0036] Example 2: Based on Example 1, the high-strength three-layer co-extruded HDPE kraft pipe provided by this utility model, such as... Figures 1 to 5 As shown: The reinforcing part 52 includes an annular rod 521 fixedly connected to the inner wall of the docking block tube 512. An annular groove 522 is provided on the inner wall of the annular rod 521. A cross rod 523 is slidably connected to the inner surface of the annular groove 522. A shaft rod 524 is fixedly passed through the side of the cross rod 523. A bottom rod 525 is fixedly connected to the outer wall of the shaft rod 524. A groove is provided on the side of the bottom rod 525 away from the shaft rod 524. An extension rod 527 is fixedly connected to the inner surface of the groove through an adjusting spring 526. A reinforcing plate 528 is fixedly connected to the outer end of the extension rod 527.

[0037] In this embodiment, the bottom end of the extension rod 527 is slidably inserted into the inner surface of the groove of the bottom rod 525, so that the position of the reinforcing plate 528 can be adjusted according to actual needs.

[0038] Furthermore, the reinforcing plate 528 is designed to be arc-shaped, and its outer wall is in contact with the connecting pipe 511 and the inner wall of the protective layer 4. The reinforcing plate can increase the strength of the connecting pipe and the protective layer, disperse the internal fluid pressure and external pressure of the Krah pipe body, prevent the Krah pipe body from deforming or breaking under pressure, and further improve the stability and overall strength of the Krah pipe body connection.

[0039] In actual operation, when this device is in use, the protective layer 4 protects the Krah tube body 1, preventing the transported medium from corroding and abrading the inner wall of the Krah tube body 1, thus extending the service life of the Krah tube body 1. At the same time, the protective layer 4 can also improve the smoothness of the inner surface of the Krah tube body 1 and reduce the resistance during fluid transport.

[0040] The two connecting pipes 3 are respectively inserted into the inner surface of the mating grooves 512 on both sides of the connecting pipe 511 to achieve the initial installation of the two carat tube bodies 1. When the mating grooves 512 of the connecting pipe 511 are connected to the connecting pipe 511, the rubber ring 513 squeezes the elastic sheet 514, causing the elastic sheet 514 to deform under pressure, and driving the connecting rod 515 to pass through the through hole 516 and extend to be inserted into the inner surface of the connecting groove 517. This makes the connection between the connecting pipe 511 and the connecting pipe 3 more secure and less prone to loosening, ensuring the overall stability of the carat tube body 1. Moreover, the elasticity of the elastic sheet 514 can buffer the impact force during the docking process to a certain extent, preventing the connection part from being damaged by external impact. At the same time, the elasticity of the rubber ring 513 allows it to fit tightly against the outer wall of the connecting pipe 3 when the connecting pipe 511 is connected to the connecting pipe 3, preventing liquid or gas leakage.

[0041] When the pressure inside the Krah tube body 1 increases, the extension rod 527 extends outward under the action of the adjusting spring 526, and the reinforcing plate 528 comes into close contact with the connecting pipe 511 and the inner wall of the protective layer 4, enhancing the pressure resistance of the connection. When the pressure decreases, the adjusting spring 526 contracts and drives the extension rod 527 back to its initial position. At the same time, the arc design of the reinforcing plate 528 fits perfectly with the connecting pipe 511 and the inner wall of the protective layer 4, which can evenly distribute the pressure and strengthen the connection from multiple angles. During the installation of the Krah tube body 1, even if there is a certain angular deviation or positional error between the connecting pipe 511 and the connecting pipe 3, fine adjustment is made by sliding the cross rod 523 in the annular groove 522, ensuring that the reinforcing plate 528 can accurately contact the connecting pipe 511 and the inner wall of the protective layer 4, achieving an effective strengthening effect.
