Description

Technical Field

[0001] This utility model relates to the field of PE water supply pipe technology, specifically a PE water supply pipe with good wear resistance. Background Technology

[0002] PE water supply pipes are widely used in the water supply pipe manufacturing industry due to their high strength, corrosion resistance, and non-toxicity. Because they do not rust, they are an ideal alternative to ordinary iron water supply pipes. Plastic pipes are developing steadily, with PE pipes, PP-R pipes, and UPVC pipes all having a place in the market. Among them, the strong development momentum of PE pipes is the most remarkable. PE pipes have a wide range of applications, with water supply pipes and gas pipes being their two largest application markets.

[0003] In the existing technology, conventional PE water supply pipes do not have elasticity and wear resistance on their inner and outer walls during use, resulting in poor wear resistance of the inner and outer walls. Long-term flushing and friction cause damage to the PE water supply pipes, reducing their service life. Furthermore, the welding method used to connect adjacent PE water supply pipes makes the joints prone to leakage, and they are also prone to breakage and damage after long-term use, lacking protection for the welded joints.

[0007] Furthermore, the outer surface of the connecting sleeve is provided with external threads.

[0008] Furthermore, the locking mechanism includes a limiting ring and a threaded sleeve.

[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] Please see Figures 1-4 This utility model discloses a PE water supply pipe with good wear resistance, including a water pipe body 1. A connecting sleeve 2 is inserted into the right end of the water pipe body 1. The connecting sleeve 2 is connected and fixed to the water pipe body 1 through a locking mechanism 3. A first protective mechanism 4 is provided on the inner wall of the water pipe body 1, and a second protective mechanism 5 is provided on the outer surface of the water pipe body 1.

[0022] Specifically, the connecting sleeve 2 has an annular groove 6 on each side facing the left and right water pipe bodies 1, and a rubber sealing ring 7 is fixedly installed on the inner wall of the annular groove 6.

[0023] In this embodiment, the left and right annular grooves 6 are used for the insertion of the ends of the left and right water pipe bodies 1, and the rubber sealing rings 7 make the annular grooves 6 fit with the ends of the water pipe bodies 1, resulting in a better sealing effect.

[0024] Specifically, the outer surface of the connecting sleeve 2 is provided with an external thread 8.

[0025] In this embodiment, the external thread 8 facilitates the threaded connection of the locking mechanism 3.

[0026] Specifically, the locking mechanism 3 includes a limiting ring 301 and a threaded sleeve 302. The limiting ring 301 is fixedly installed on the outer surface of the water pipe body 1, and the threaded sleeve 302 is movably sleeved on the water pipe body 1 corresponding to the limiting ring 301. The threaded sleeve 302 is threadedly installed on the outer surface of the connecting sleeve 2.

[0027] In this embodiment, the limiting ring 301 is used to limit the threaded sleeve 302, so that the threaded sleeve 302 is threaded onto the connecting sleeve 2 through the external thread 8, so that the water pipe body 1 can be stably connected to the connecting sleeve 2, and the connection is firm and stable.

[0028] Specifically, the first protective mechanism 4 includes a first elastic coating 401, an antistatic coating 402, and an antibacterial coating 403. The first elastic coating 401 is applied to the inner wall of the water pipe body 1. The first elastic coating 401 is coated with an antistatic coating 402, and the antistatic coating 402 is coated with an antibacterial coating 403.

[0029] In this embodiment, the first elastic coating 401 is enhanced with an antistatic coating 402 and an antibacterial coating 403, which increases the buffering and wear resistance of the water pipe body 1, making the inner wall of the water pipe body 1 less susceptible to erosion and damage. The antistatic coating 402 and the antibacterial coating 403 enhance the antistatic and antibacterial functions of the water pipe body 1, making it safe and hygienic to use.

[0030] Specifically, the second protective mechanism 5 includes a second elastic coating 501, a heat insulation coating 502, a flame retardant coating 503, and a wear-resistant coating 504, which are applied sequentially from the inside to the outside on the outer surface of the water pipe body 1.

[0031] In this embodiment, the second elastic coating 501 adds buffering function to the heat insulation coating 502, flame retardant coating 503 and wear-resistant coating 504, making the heat insulation coating 502, flame retardant coating 503 and wear-resistant coating 504 less susceptible to impact damage, improving the wear resistance of the outer surface of the water pipe body 1. The heat insulation coating 502 has a better heat insulation effect between the inside and outside of the water pipe body 1, and the flame retardant coating 503 increases the flame retardant performance of the outer surface of the water pipe body 1.

[0032] Specifically, the thickness of the first elastic coating 401 and the second elastic coating 501 is 1.5mm-2mm.

[0033] In this embodiment, both the first elastic coating 401 and the second elastic coating 501 have good elasticity, and the first elastic coating 401 and the second elastic coating 501 are made of inorganic polymer materials, such as alkali metals and silica sol.

[0034] In use, the left and right water pipe bodies 1 are respectively inserted into the annular grooves 6 on the left and right sides of the connecting sleeve 2. The locking mechanism 3 uses the limiting ring 301 to limit the threaded sleeve 302, so that the threaded sleeve 302 is threaded onto the connecting sleeve 2 through the external thread 8. This allows the water pipe body 1 to be stably connected to the connecting sleeve 2, and the end of the water pipe body 1 is tightly fitted with the rubber sealing ring 7. The inner and outer sides of the water pipe body 1 are fitted with the upper and lower inner walls of the annular groove 6. The first elastic coating 401 in the first protective mechanism 4 adds an antistatic coating 402 and an antibacterial coating 403, which increases the internal cushioning and wear resistance of the water pipe body 1. The performance of the coating makes the inner wall of the water pipe body 1 less susceptible to erosion damage. The antistatic coating 402 and antibacterial coating 403 increase the antistatic and antibacterial functions of the water pipe body 1, making it safe and hygienic to use. The second elastic coating 501 in the second protective mechanism 5 increases the buffer function of the heat insulation coating 502, flame retardant coating 503 and wear-resistant coating 504, making the heat insulation coating 502, flame retardant coating 503 and wear-resistant coating 504 less susceptible to impact damage, improving the wear resistance of the outer surface of the water pipe body 1. The heat insulation coating 502 has a good heat insulation effect between the inside and outside of the water pipe body 1, and the flame retardant coating 503 increases the flame retardant performance of the outer surface of the water pipe body 1.

[0035] In summary, this wear-resistant PE water supply pipe increases the elasticity and wear resistance of the inner and outer walls of the main body 1, giving the main body 1 better wear resistance, making it less susceptible to damage when subjected to scouring and friction, thus extending its service life. At the same time, the connection between adjacent main bodies 1 is tighter, and the protection function of the ends of the main bodies 1 is increased, making the connection more stable and secure.
