Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, specifically to a pressure-resistant and impact-resistant PE pipe. Background Technology

[0002] PE pipe is a type of pipe made primarily from polyethylene resin through an extrusion molding process. PE pipe possesses numerous excellent properties, making it outstanding in many application areas. Its wide range of applications, including excellent chemical corrosion resistance and high insulation strength, allows it to maintain a relatively stable form under various usage conditions.

[0003] A search revealed a PE pipe with high impact resistance, disclosed in publication number CN214305641U. This pipe includes a PE pipe body with a surface protective layer, designed to address the problems of wear and aging that occur with existing PE pipes during use. However, this practical PE pipe only adds internal material structures to enhance its strength, lacking internal support structures. Consequently, it is easily damaged when impacted at pipe joints. Therefore, we propose a pressure-resistant and impact-resistant PE pipe. Utility Model Content

A flow guide hole is opened on the upper outer wall of the guide plate. A clamping plate is fixed on the lower outer surface of the pipe body near the guide plate end.

[0007] A PE inner liner is disposed in the innermost layer of the pipe body. A metal braided mesh layer is laid on the outer surface of the PE inner liner. An organosilicon resin layer is arranged around the outer surface of the metal braided mesh layer. A PE outer liner is fixed to the outer surface of the organosilicon resin layer.

Detailed Implementation

[0020] 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 protection scope of the present utility model.

[0021] This utility model provides an improved PE pipe that is pressure-resistant and impact-resistant. Please refer to [link / reference]. Figures 1-3 The system includes: a pipe body 1, with an external thread 2 on the outer wall of one end of the pipe body 1, and a connecting ring 3 fixed to the other end of the pipe body 1. The inner side of the connecting ring 3 has an internal thread 4 that matches the external thread 2. The internal thread 4 and the external thread 2 are mutually matched, and the pipe bodies 1 are connected by the external thread 2, the connecting ring 3, and the internal thread 4. The internal thread 4 on the inner wall of the connecting ring 3 is used to connect and tighten with the external thread 2 on the pipe body 1. A sealing ring is added to prevent leakage at the connection point. A guide is connected to the inner surface of the pipe body 1 near the external thread 2 via a rotating shaft. A guide plate 5 is provided, and a rotating connection is formed between the guide plate 5 and the pipe body 1. The rotating shaft is used to allow the guide plate 5 to rotate smoothly inside the pipe body 1. A reinforcing plate 6 is fixed in the middle of the guide plate 5. A flow guide hole 7 is provided on the upper outer wall of the guide plate 5. The flow guide hole 7 is evenly distributed at equal intervals along the upper outer wall of the guide plate 5. The flow guide hole 7 is used to allow the fluid in the pipe to flow smoothly at the upper end of the guide plate 5. A retaining plate 8 is fixed on the lower outer surface of the pipe body 1 near the guide plate 5. The guide plate 5 and the pipe body 1 are connected by a retaining plate 8 to form a locking structure. The retaining plate 8 is used to restrict the rotation of the guide plate 5. The pipe body 1 is oriented to prevent backflow of the transported medium. The innermost layer of the pipe body 1 is a PE inner liner 9. A metal braided mesh layer 10 is laid on the outer surface of the PE inner liner 9. An organosilicon resin layer 11 is arranged around the outer surface of the metal braided mesh layer 10. A PE outer liner 12 is fixed to the outer surface of the organosilicon resin layer 11. The PE outer liner 12, through the PE inner liner 9, the metal braided mesh layer 10, and the organosilicon resin layer 11, forms an enclosing structure. The pipe body 1, through the metal braided mesh layer 10 and the organosilicon resin layer 11, provides auxiliary structural support, enabling… The pressure and impact resistance of the pipe body is improved. With the segmented rotatable guide plate 5, the pressure resistance of the pipe body 1 at the connection is further improved, preventing the pipe body 1 from breaking due to reduced strength at the connection during use. The outer surface of the PE outer liner 12 is coated with an anti-corrosion coating 13, and the inner surface of the anti-corrosion coating 13 is tightly bonded to the outer surface of the PE outer liner 12. The epoxy resin anti-corrosion coating 13 is used to enhance the surface oxidation and corrosion resistance of the pipe body 1, and improve the durability of the pipe body 1 during use.

[0022] Please see Figure 1 and Figure 4 A pressure-resistant and impact-resistant PE pipe includes: a fastening ring 14 bolted onto the outer surface of a connecting ring 3; a connecting block 15 fixed to the adjusting end of the fastening ring 14; a connecting hole 16 formed on the outer surface of the connecting block 15; the connecting hole 16 being symmetrically arranged about the central axis of the connecting block 15; and the fastening ring 14 forming a threaded connection with the connecting ring 3 through the connecting block 15 and the connecting hole 16. The fastening ring 14 is used to tighten and fix itself to the surface of the connecting ring 3 by fasteners. The fasteners are tightened inside the connecting hole 16 of the connecting block 15, so that the fastening ring 14 tightens and fixes the connecting ring 3, preventing the connecting ring 3 from slipping off at one end of the pipe body 1, and improving the tightness of the pipe body 1 after connection.

[0023] Working Principle: For this type of pressure-resistant and impact-resistant PE pipe, the operator first selects an appropriate number of pipe bodies 1 according to the operational requirements. A guide plate 5 is connected to the inner wall of one end of each pipe body 1 via a rotating shaft. The guide plate 5, with its rotating shaft in the middle, is reinforced with a stainless steel reinforcing plate 6 to prevent it from detaching from the inner wall of the pipe body 1. The pipe bodies 1 are connected by external threads 2 and internal threads 4 on the inner side of the connecting ring 3. A sealing ring is added at the connection point to enhance airtightness. When the pipe bodies 1 are connected and the medium is being transported, the transported medium pushes the guide plate 5 to rotate. When the guide plate 5 is closed during operation, it provides support and pressure resistance to the end of the pipe body 1. Furthermore, because the guide plate 5 has a flow-guiding hole 7 at its upper end, it always moves away from the clamping plate 8. The rotating plate 8 effectively prevents backflow of the medium inside the pipe body 1, allowing the transported medium to accumulate in segments inside multiple sections of the pipe body 1 when it stops flowing, balancing the pressure inside the pipe. Finally, the pipe body 1 acts as a structural frame through the PE inner lining layer 9 and the PE outer lining layer 12. The internal filling of the metal braided mesh layer 10 and the silicone resin layer 11 enhances the pressure resistance and impact resistance of the pipe body 1, preventing deformation of the pipe body 1 under pressure. The anti-corrosion coating 13 applied to the outermost layer of the pipe body 1 improves the anti-corrosion and anti-oxidation capabilities of the pipe body 1, extending its service life. Furthermore, a fastening ring 14 is fitted at the connecting ring 3 of the pipe body 1, which is fastened by fasteners and connecting blocks 15. When the fasteners connect and tighten the two ends of the fastening ring 14 through the connecting holes 16, they can tighten the connection between the connecting ring 3 and the pipe body 1, improving the stability of the connection.
