[0018] 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.
[0019] Please see Figure 1-3 This utility model provides a technical solution for a protective sleeve for a three-way pipe: it includes a protective sleeve body 1, which is composed of three interconnected protective pipes 2, corresponding to the three branch pipes of the three-way pipe. The protective sleeve body 1 has a pipe receiving cavity adapted to the three-way pipe inside. The protective sleeve body 1 includes an upper shell 3 and a lower shell 4, which are integrally formed. One side of the upper shell 3 and the lower shell 4 is hinged. Pipe leakage warning components 5 are fixedly installed on both sides of the upper shell 3 and the lower shell 4. The pipe leakage warning components 5 include a collection pipe 6, a collection bottle 7, and a collection trough 8. The collection pipe 6 is located at the bottom of the lower shell 4. Another collection pipe 6 is also located above the upper shell 3. The collection pipe 6 communicates with the interior of the upper shell 3 and the lower shell 4. The collection trough 8 is located on the inner wall of the upper shell 3 and the lower shell 4, and the collection trough 8 communicates with the collection pipe 6.
[0020] Furthermore, the collection tank 8 is provided in three sets, and each set of collection tank 8 is correspondingly located inside three protective tubes 2.
[0021] In this embodiment, each set of collection tanks 8 extends along the inner wall of the protective pipe 2 to ensure that in the event of a leak in the pipe, the leaked liquid can be effectively collected and guided to the collection pipe 6.
[0022] Furthermore, a sealing cap 9 is threaded onto the collection pipe 6 of the upper housing 3, and a collection bottle 7 is threaded onto the collection pipe 6 of the lower housing 4.
[0023] Furthermore, the collection bottle 7 is provided with a transparent display window 10.
[0024] In this embodiment, the transparent display window 10 facilitates observation of the liquid collected inside the collection bottle 7, thereby enabling timely detection of any pipeline leaks. When a leak occurs in the tee pipe, the leaked liquid flows into the collection bottle 7 through the collection pipe 6. By observing the transparent display window 10, staff can directly observe the changes in the liquid inside the collection bottle 7, thus determining whether the pipeline is leaking and the extent of the leak. This not only improves the convenience of pipeline leak detection but also helps to promptly identify and address leaks, ensuring the safe operation of the pipeline system.
[0025] Furthermore, connecting ears 11 are fixedly installed on the outer side walls of both the upper housing 3 and the lower housing 4, and the positions of the connecting ears 11 of the upper housing 3 and the lower housing 4 correspond to each other. The connecting ears 11 are provided with screw holes.
[0026] In this embodiment, the upper housing 3 and the lower housing 4 can be tightly fixed together by bolts, which enhances the overall stability and sealing, and prevents the upper housing 3 and the lower housing 4 from separating due to accidental collisions or vibrations during use, thereby effectively protecting the tee pipe.
[0027] Furthermore, a sealing ring 12 is provided on the inner wall of the protective tube 2, and the sealing ring 12 is located at the opening of the protective tube 2.
[0028] In this embodiment, the sealing ring 12 is made of rubber, which has good elasticity and sealing performance. It can effectively prevent liquid or gas in the pipeline from leaking from the opening of the protective pipe 2, thereby improving the sealing performance and safety of the tee pipe protective sleeve.
[0029] Furthermore, an insulation layer is provided on the outer wall of the protective pipe 2, the insulation layer being made of polyurethane foam material, and an anti-corrosion and wear-resistant layer is provided on the inner wall of the protective pipe 2, the anti-corrosion and wear-resistant layer being made of polymer composite material.
[0030] In this embodiment, the polymer composite material exhibits excellent corrosion resistance and wear resistance, effectively extending the service life of the protective pipe. The polyurethane foam material, as an insulation layer, provides good thermal insulation, effectively reducing heat loss from the pipe's interior and improving its insulation performance. This design not only enhances the pipe's protective performance but also improves its utilization efficiency.
[0031] Working principle: When a leak occurs in the tee pipe, the leaking liquid flows through the protective pipe 2 into the collection tank 8, then along the collection tank 8 into the collection pipe 6. The leaking liquid then flows through the collection pipe 6 on the lower housing 4 into the collection bottle 7. The transparent display window 10 on the collection bottle 7 allows for easy observation of the amount of leaked material, enabling timely handling. Simultaneously, the upper housing 3 and lower housing 4 are hinged together, allowing for easy opening and closing, facilitating the installation, disassembly, and maintenance of the tee pipe. Furthermore, the sealing ring 12 on the inner wall of the protective pipe 2 improves the seal between the protective sleeve body 1 and the tee pipe, preventing leakage. The insulation layer on the outer wall of the protective pipe 2 and the corrosion-resistant and wear-resistant layer on the inner wall enhance the insulation and corrosion resistance of the protective sleeve body 1, extending its service life.
