Description

Technical Field

[0001] This utility model relates to the field of water supply pipeline technology, and in particular to an explosion-proof water supply pipeline. Background Technology

[0002] In the field of building and municipal engineering, water supply pipeline systems are critical infrastructure for ensuring the normal operation of residential water use, industrial production water use, and public facilities. Traditional water supply pipes, such as steel pipes, cast iron water supply pipes, and reinforced concrete pipes, were once widely used in building construction and municipal water supply networks. However, these pipe materials have many drawbacks that cannot be ignored.

[0003] From an architectural perspective, in modern cities filled with high-rise buildings, water supply pipes need to deliver water to every corner of different floors. Traditional pipe materials, due to their inherent properties, are prone to fatigue and damage when subjected to the high water pressure of high-rise buildings. For example, steel pipes are susceptible to corrosion, leading to thinner pipe walls and reduced pressure resistance; cast iron pipes are brittle and easily rupture under external impact or water pressure fluctuations. This not only affects the normal water use within the building but can also damage the building structure, causing problems such as wall leaks and short circuits in electrical equipment, posing threats to residents' lives and safety.

[0004] In municipal engineering, urban water supply networks act as the "blood vessels" of a city, covering a wide area and involving complex routes. Traditional water supply pipelines, over long-term use, are prone to aging and damage due to factors such as soil environment, groundwater level changes, and surrounding construction. This aging problem is particularly severe in older urban areas, where pipe bursts are frequent. A pipe burst not only causes widespread water outages, disrupting residents' daily lives and businesses' normal operations, but also leads to water waste and environmental pollution. Furthermore, timely pipeline repair requires significant investment of manpower, resources, and funds for emergency repairs and maintenance, increasing the city's operating costs.

[0005] In addition, traditional water supply pipes also have certain limitations in terms of connection and installation. For example, some pipe connections are not secure enough, making them prone to loosening and leakage; when repairing or replacing pipes, the disassembly and installation process is cumbersome, requiring a lot of time and effort, which affects construction efficiency and the stability of water supply.

[0006] While existing technologies, such as the novel water supply pipe with publication number CN214466786U, have addressed issues like pipe connection sealing and scale buildup prevention to some extent, significant shortcomings remain. This new type of water supply pipe lacks a buffer layer when facing high water pressure, failing to effectively cushion the pressure on the inner pipe and making it prone to rupture over time. Furthermore, although threaded connections are used, they are susceptible to corrosion and difficult to disassemble and maintain, causing considerable inconvenience in building construction and municipal pipeline renovation.

[0007] Therefore, developing a highly practical, simple, and effective explosion-proof water supply pipeline that can solve buffering and installation / disassembly problems is of great significance for the safe and stable operation of water supply systems in the building and municipal sectors.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] Please see Figures 1 to 6 This utility model provides a technical solution:

[0034] An explosion-proof water supply pipe has broad application prospects in the construction and municipal fields. It can effectively solve the problems existing in traditional water supply pipes and provide strong protection for the stable operation of water supply systems.

[0035] The explosion-proof water supply pipeline mainly includes an inner pipe 1, which is the part of the entire pipeline system that directly contacts water. Therefore, the selection of the material for the inner pipe 1 is crucial. In this embodiment, the inner pipe 1 is made of high-strength, corrosion-resistant polyethylene material. This material has good flexibility and chemical corrosion resistance, and can effectively resist the erosion of various chemicals in the water, ensuring that the water quality is not polluted.

[0036] An explosion-proof membrane 2 is fixedly connected to the surface of the inner tube 1. The explosion-proof membrane 2 adopts a multi-layer composite structure, composed of a high-strength polyester film and a special adhesive. Its function is to prevent water from spraying out directly after the inner tube 1 ruptures when the pipeline is subjected to accidental impact or a sudden increase in water pressure, thus providing a certain degree of buffering and protection. The explosion-proof membrane 2 is tightly adhered to the surface of the inner tube 1 through a special process, ensuring a firm and reliable connection between the two.

[0037] A filling layer 3 is fixedly connected to the surface of the explosion-proof membrane 2. The filling layer 3 is made of sound-absorbing and heat-insulating foam material. Its main function is to reduce the noise generated when water flows in the pipe, and at the same time, it plays a certain role in heat insulation to prevent the water temperature in the pipe from being affected by the external ambient temperature. The thickness of the filling layer 3 is reasonably designed according to the usage environment and requirements of the pipe, and is generally between 10-20mm.

[0038] A buffer layer 4 is fixedly connected to the surface of the filling layer 3. The buffer layer 4 is one of the key structures of this invention. It includes a spring 9 fixedly connected to the surface of the filling layer 3. The spring 9 is made of high-strength alloy steel and has good elasticity and compressive strength. A rubber ring A10 is fixedly connected inside the spring 9, which fixes the spring 9 and prevents it from shifting under pressure. A clamping block 11 is fixedly connected to the top surface of the rubber ring A10. The clamping block 11 is made of high-strength plastic and has a certain degree of rigidity and toughness. A rubber ring B12 is fixedly connected to the top surface of the clamping block 11, which also serves a fixing function and further enhances the buffering effect of the buffer layer 4. When water flows in the inner pipe 1 and generates water pressure, the synergistic effect of the spring 9 and rubber ring A10, and the clamping block 11 and rubber ring B12 in the buffer layer 4 can effectively absorb and mitigate these pressure shocks, reduce damage to pipes and other accessories, and improve the stability and reliability of the system.

[0039] A braided layer 5 is fixedly connected to the surface of the buffer layer 4. The braided layer 5 is woven from high-strength fiber materials, such as carbon fiber or aramid fiber. The function of the braided layer 5 is to enhance the overall strength and toughness of the pipeline, preventing deformation or breakage when the pipeline is subjected to external forces. The braided layer 5 is woven in a cross-weave manner, which allows the fibers to intertwine and form a tight whole, improving the tensile and tear resistance of the pipeline.

[0040] An outer tube 6 is fixedly connected to the surface of the braided layer 5. The outer tube 6 is made of high-strength polyvinyl chloride material, which has good wear resistance, weather resistance, and UV resistance. The main function of the outer tube 6 is to protect the internal structure from the influence of the external environment, while also providing a certain degree of pressure resistance and protection. The thickness of the outer tube 6 is rationally designed according to the pipeline's operating environment and requirements, generally between 5-10 mm.

[0041] Both ends of the outer pipe 6 are fixedly connected to flanges 7. Flanges 7 are made of stainless steel, offering excellent corrosion resistance and high strength. A groove is formed inside the flange 7, and a sealing ring made of rubber fits inside the groove to provide a seal and prevent leakage at the pipe connection. Connecting components 8 are fitted onto the surface of the flange 7.

[0042] The connecting assembly 8 includes a connecting block A801 ​​that fits onto the surface of the flange 7, with a connecting block B802 rotatably connected to one end of A801. Both connecting blocks A801 ​​and B802 are made of high-strength aluminum alloy, featuring light weight and high strength. A ball bearing 803, made of stainless steel with a smooth surface, is rotatably connected to the other end of A801, reducing friction during rotation. A threaded rod 804 is fixedly connected to one side of the ball bearing 803, and a threaded cap 805 is threaded onto the surface of the threaded rod 804. A sliding hole is provided on one side of the connecting block B802, which is adapted to the threaded rod 804. Through the connection assembly 8, during use, the flanges 7 are connected to each other, connecting blocks A801 ​​and B802 are fitted onto their surfaces, the threaded rod 804 is rotated into the sliding hole, and the threaded cap 805 is tightened to lock connecting blocks A801 ​​and B802 together, thus connecting the pipes. This connection method is not only convenient and quick, but also secure, while avoiding the problems of corrosion and inconvenience of disassembly associated with traditional connection methods.

[0043] To further improve the explosion-proof performance and practicality of the pipeline, a pressure monitoring device and an automatic drain valve are added in this embodiment. The pressure monitoring device is installed on the inner pipe 1 and can monitor the water pressure in the pipeline in real time, transmitting the data to the monitoring center. When the water pressure exceeds the set safety value, the monitoring center can take timely measures, such as adjusting the operating parameters of the water pump or closing relevant valves, to ensure the safe operation of the pipeline. The automatic drain valve is installed at the lowest point of the pipeline. When the water in the pipeline stops flowing or the pressure is abnormal, the automatic drain valve will automatically open to drain the accumulated water in the pipeline, preventing the pipeline from cracking due to freezing.

[0044] In this utility model, the working steps of the device are as follows: First step: In use, first align the flanges 7 at both ends of the pipe, then fit the connecting block A801 ​​and connecting block B802 onto the surface of the flange 7. Next, rotate the threaded rod 804 so that it passes through the sliding hole on the connecting block B802, and finally tighten the threaded cap 805 until the connecting block A801 ​​and connecting block B802 are tightly locked, so that the pipes are firmly connected. Second step: When water flows in the inner pipe 1, a certain water pressure is generated. At this time, the spring 9 in the buffer layer 4 will be compressed, and the rubber ring A10, clamp 11 and rubber ring B12 will work together to absorb and alleviate these pressure shocks, reducing damage to the pipe. At the same time, the pressure monitoring device will monitor the water pressure in the pipe in real time. Once the water pressure exceeds the safe value, the monitoring center will take corresponding measures in time. When the water in the pipe stops flowing or the pressure is abnormal, the automatic drain valve will automatically open to drain the water in the pipe.

[0045] Through the above specific implementation methods, the explosion-proof water supply pipeline of this utility model has higher practicality and reliability in the construction and municipal fields, can effectively solve the problems existing in traditional water supply pipelines, and provide a more stable and safe guarantee for the urban water supply system.
