[0001] This utility model relates to the field of pipe protective sleeve technology, specifically a pipe protective sleeve with protective properties. Background Technology

[0002] Pipelines are widely used in many fields such as industrial production, urban water supply, and heating. However, during use, pipelines are often affected by various factors, such as external mechanical impacts, corrosive media, and temperature changes. These factors can lead to pipeline damage and leaks, which not only affect the normal use of pipelines and waste resources, but may also cause safety accidents. Currently, most pipeline protective sleeves on the market have relatively limited functions, such as only providing corrosion protection or heat insulation, which is insufficient to meet the comprehensive protection needs of pipelines under complex working conditions.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a pipe protective sleeve with protective performance: it includes a protective sleeve body 1, which is sleeved on the outside of a pipe 2. The protective sleeve body 1 includes a first sleeve 3, a second sleeve 4, and a third sleeve 5. The second sleeve 4 and the third sleeve 5 are respectively installed at both ends of the first sleeve 3. A first connecting flange 6 is fixedly provided at the other end of the second sleeve 4, and a second connecting flange 7 is fixedly provided at the other end of the third sleeve 5. The second sleeve 4 and the third sleeve 5 are slidably connected at both ends of the first sleeve 3. A first sliding groove 8 for installing the second sleeve 4 is provided on one side of the first sleeve 3, and a second sliding groove 9 for installing the third sleeve 5 is provided on the other side of the first sleeve 3. The first sleeve 3, the second sleeve 4, and the third sleeve 5 each include an inner protective layer 10, a middle protective layer 11, and an outer protective layer 12, which are sequentially and tightly fitted together.

[0021] Furthermore, the second sleeve 4 has a first limiting block 13 fixedly installed at one end located in the first slide groove 8, and the third sleeve 5 has a second limiting block 14 fixedly installed at one end located in the second slide groove 9.

[0022] In this embodiment, the first limiting block 13 and the second limiting block 14 effectively limit the sliding range of the second sleeve 4 and the third sleeve 5 on the first sleeve 3, thereby ensuring the stability and safety of the pipe protective sleeve during use. The first limiting block 13 is tightly fitted with the inner wall of the first sliding groove 8, and the second limiting block 14 is also tightly fitted with the inner wall of the second sliding groove 9. This design not only enhances the stability of the sliding connection, but also prevents the second sleeve 4 and the third sleeve 5 from accidentally falling off.

[0023] Furthermore, the inner wall of the first slide groove 8 is provided with a first sealing ring 15, and the inner wall of the second slide groove 9 is provided with a second sealing ring 16.

[0024] In this embodiment, the first sealing ring 15 and the second sealing ring 16 further enhance the sealing performance of the pipe protective sleeve. During the relative sliding process of the first sleeve 3, the second sleeve 4, and the third sleeve 5, the first sealing ring 15 can fit tightly between the second sleeve 4 and the inner wall of the first groove 8, effectively preventing moisture, dust, and other impurities from entering the groove and avoiding jamming or damage to the groove due to the accumulation of impurities. Similarly, the second sealing ring 16 can also fit tightly between the third sleeve 5 and the inner wall of the second groove 9, providing the same protective effect.

[0025] Furthermore, annular retaining rings 17 are fixedly provided at both ends of the first sleeve 3.

[0026] In this embodiment, the retaining ring 17 can cooperate with the first limiting block 13 and the second limiting block 14 to jointly limit the sliding range of the second sleeve 4 and the third sleeve 5, and prevent them from falling off the first sleeve 3.

[0027] Furthermore, the inner protective layer 10 is a heat insulation layer made of ceramic fiber material with high temperature resistance and good heat insulation performance. This material can effectively insulate the high temperature inside the pipe and prevent heat from being transferred to the external environment. At the same time, it can also prevent the low temperature in the external environment from affecting the inside of the pipe, thereby protecting the pipe and its internal medium from the effects of temperature changes.

[0028] Furthermore, the intermediate protective layer 11 is a buffer layer made of polyurethane foam. Polyurethane foam has good elasticity and cushioning properties, which can effectively absorb external mechanical impacts and prevent the pipeline from being damaged by collisions.

[0029] Furthermore, the outer protective layer 12 is a corrosion-resistant layer made of high-density polyethylene (HDPE) material, with an anti-corrosion coating applied to its surface. HDPE itself has good corrosion resistance, and the anti-corrosion coating further enhances its corrosion resistance, effectively resisting the erosion of various corrosive media and thus extending the service life of the pipe protective sleeve. In addition, HDPE also has good wear resistance and anti-aging properties, enabling it to withstand long-term erosion from the external environment and maintain the appearance and function of the pipe protective sleeve.

[0030] Working Principle: In use, pipe 2 is first placed inside the protective sleeve body 1. Then, by sliding the second sleeve 4 and the third sleeve 5, the first connecting flange 6 and the second connecting flange 7 are fixedly connected to both ends of pipe 2, respectively. Since the second sleeve 4 and the third sleeve 5 are slidably connected to both ends of the first sleeve 3, and the first sleeve 3 has a first groove 8 on one side and a second groove 9 on the other side, the positions of the second sleeve 4 and the third sleeve 5 can be flexibly adjusted according to the length of pipe 2, ensuring that the protective sleeve body 1 can be tightly fitted onto the outside of pipe 2. At the same time, the first limiting block 13 and the second limiting block 14 can effectively prevent the second sleeve 4 and the third sleeve 5 from sliding excessively in the first groove 8 and the second groove 9, ensuring the stability of the connection. In addition, the first sealing ring 15 and the second sealing ring 16 can improve the sealing performance of the protective sleeve body 1 and prevent the intrusion of external media.
