Description

Technical Field

[0001] This utility model relates to the field of pipeline replacement technology, specifically a lead-free copper PPR anti-freeze cracking reducer. Background Technology

[0002] In building water supply and drainage, HVAC, and industrial fluid transportation, reducing adapters are key components for connecting pipes of different diameters. They effectively connect large-diameter pipes to small-diameter pipes, ensuring a smooth transition of fluid within the piping system and meeting diverse engineering needs. With their flexible connection methods and adaptability to different pipe diameters, reducing adapters are widely used in various pipeline construction and renovation projects, ensuring the integrity and functionality of the entire pipeline system.

[0003] However, existing reducing adapters lack specific anti-freeze-crack designs and lack effective structural or technical measures to resist low-temperature freezing damage, making it difficult to meet the needs of safe operation of pipeline systems in cold regions during winter. In winter in cold regions, when the ambient temperature drops sharply below freezing, the water in the pipeline freezes and expands, generating enormous expansion pressure. At this time, some reducing adapters made of rigid plastic or traditional metal materials are prone to cracking and damage due to their reduced toughness at low temperatures and the expansion force generated by the freezing water. Once a reducing adapter freezes and cracks, it not only leads to water leakage in the pipeline system, affecting normal water supply or fluid transportation, but may also trigger a series of secondary disasters, such as damage to indoor decorations and equipment malfunctions due to immersion, causing significant economic losses and inconvenience to users. Utility Model Content

[0004] The purpose of this invention is to provide a lead-free copper PPR anti-freeze crack reducer connector to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A lead-free copper PPR anti-freeze crack reducer connector includes a reducer body. The top surface of the reducer body has a first threaded hole, and the bottom surface has a second threaded hole. The reducer body has an internal conical cavity that connects to the first and second threaded holes. A connecting block is installed at the center of the outer side of the reducer body. Connecting rings are installed on both ends of the outer side of the reducer body. A corrugated tube is installed on the side of each connecting ring near the connecting block. The corrugated tube and the connecting block are magnetically connected. Insulation cotton is adhered to the inner wall of the corrugated tube. The inner surface of the reducer body... The unit features a vacuum chamber, and the first and second threaded holes can be threaded to pipes of different diameters to achieve diameter conversion. The tapered cavity allows for a smooth transition of fluid between pipes of different diameters, reducing fluid resistance. The connecting block facilitates gripping and securing the conversion joint during installation. The connecting ring is used to fix the bellows. The bellows has a certain degree of elasticity and can cover the conversion head body of different lengths. The insulation cotton reduces heat loss and provides insulation for the fluid inside the pipe, reducing the risk of fluid freezing. The vacuum chamber utilizes the principle of vacuum insulation to further enhance the insulation effect and prevent the internal fluid from freezing due to excessively low surface temperature of the conversion head body.

[0007] Furthermore, annular grooves are provided on both sides of the connecting block, and magnets are embedded in the bottom surface of the annular grooves. A metal ring is installed on the free section of the corrugated pipe. The metal ring and the annular groove are locked together and attracted to each other with the magnets. The locking structure of the annular groove and the metal ring makes the connection between the corrugated pipe and the connecting block more stable and prevents the corrugated pipe from falling off during use. The attraction between the magnet and the metal ring further enhances the reliability of the connection and facilitates the installation and disassembly of the corrugated pipe.

[0008] Furthermore, the connecting ring and the adapter body are connected by a threaded engagement. This threaded engagement ensures a tight and secure connection between the connecting ring and the adapter body, facilitating installation and disassembly. Additionally, the position of the connecting ring on the adapter body can be adjusted as needed to ensure that the insulation cotton covers most of the area of ​​the adapter body.

[0009] Furthermore, the length of the vacuum chamber is greater than the length of the conical cavity, and the vacuum chamber covers the conical cavity and more areas, expanding the insulation range and ensuring that the entire fluid channel can be well insulated, thereby further improving the antifreeze effect.

[0010] Furthermore, the end of the conical cavity with the larger radius is connected to the first threaded hole, and the end of the conical cavity with the smaller radius is connected to the second threaded hole. This design achieves a smooth transition from a large pipe diameter to a small pipe diameter, allowing the fluid velocity to gradually increase during the flow process, resulting in a more uniform pressure distribution, reduced fluid resistance and energy loss, and avoiding fluid impact and noise caused by sudden changes in pipe diameter.

[0011] Furthermore, the cross-section of the connecting block is a regular hexagon. The regular hexagonal cross-section facilitates clamping and rotation using tools such as wrenches, making it convenient for the installation and disassembly of the adapter and improving construction efficiency.

[0012] Furthermore, the adapter body is made of metal, specifically lead-free copper, which possesses excellent strength, corrosion resistance, and thermal conductivity. High strength ensures the adapter is not easily deformed or broken during use; strong corrosion resistance prevents corrosion from prolonged contact with fluids, extending its service life; good thermal conductivity facilitates insulation through a vacuum chamber and insulation cotton; and lead-free copper meets environmental protection requirements, preventing lead and other harmful substances from contaminating the fluid.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the lead-free copper PPR anti-freeze crack reducer can be connected to pipes of different diameters through the first and second threaded holes to achieve diameter conversion; the conical cavity allows the fluid to transition smoothly between pipes of different diameters, reducing fluid resistance; the connecting block facilitates gripping and fixing of the reducer during installation; the connecting ring is used to fix the bellows; the bellows has a certain degree of elasticity and can cover the reducer body of different lengths; the insulation cotton can reduce heat loss and keep the fluid in the pipe warm, reducing the risk of fluid freezing; the vacuum cavity utilizes the principle of vacuum insulation to further enhance the insulation effect and prevent the internal fluid from freezing due to excessively low surface temperature of the reducer body.

[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 1-5 This utility model provides a technical solution: a lead-free copper PPR anti-freeze crack reducing adapter, including an adapter body 1. The top surface of the adapter body 1 has a first threaded hole 5, and the bottom surface of the adapter body 1 has a second threaded hole 9. The interior of the adapter body 1 has a conical cavity 8, which connects to the first threaded hole 5 and the second threaded hole 9. A connecting block 2 is installed on the middle of the outer side of the adapter body 1. Connecting rings 3 are installed on the outer side of the adapter body 1 near both ends. Corrugated pipes 4 are installed on the side of the connecting rings 3 near the connecting block 2. The corrugated pipes 4 and the connecting block 2 are connected by adsorption. Insulation cotton 11 is adhered to the inner wall of the corrugated pipes 4. A vacuum cavity 10 is opened inside the adapter body 1. During installation, the adapter is connected to pipes of different diameters through the first threaded hole 5 and the second threaded hole 9. At the same time, PTFE tape needs to be wrapped around the pipe. Fluid enters from the first threaded hole 5, flows through the conical cavity 8 to the second threaded hole 9, and realizes the changing diameter conveying. When the ambient temperature drops, the insulation cotton 11 and the vacuum chamber 10 work together to reduce heat loss from the adapter, keep the internal fluid temperature above freezing, and reduce the possibility of cracking of the adapter body 1.

[0022] In one embodiment of this utility model, annular grooves 7 are further provided on both sides of the connecting block 2. Magnets are embedded in the bottom surface of the annular grooves 7. A metal ring 6 is installed on the free section of the corrugated pipe 4. The metal ring 6 engages with the annular grooves 7 and attracts the magnets. When installing the corrugated pipe 4, the metal ring 6 is aligned with the annular groove 7 and inserted. Simultaneously, the metal ring 6 engages with the annular groove 7 and is tightly fixed within the annular groove 7 by the magnetic attraction. When the corrugated pipe 4 is subjected to external force, the engagement of the metal ring 6 with the annular groove 7 and the magnetic attraction work together to resist the external force, ensuring that the corrugated pipe 4 will not detach from the connecting block 2. For disassembly, the metal ring 6 can be removed from the annular groove 7 simply by overcoming the magnetic attraction.

[0023] In one embodiment of this utility model, the connecting ring 3 and the converter body 1 are further connected by threaded engagement. By rotating the connecting ring 3, it engages with the threads on the converter body 1 to achieve a tight connection. During installation, the connecting ring 3 is screwed into the appropriate position on the converter body 1 to ensure that the bellows 4 is installed in the correct position; during disassembly, the connecting ring 3 can be removed by screwing it in the opposite direction.

[0024] As an embodiment of this utility model, the length of the vacuum chamber 10 is greater than the length of the conical cavity 8. Since the length of the vacuum chamber 10 is greater than that of the conical cavity 8, the entire flow channel is within the heat preservation range of the vacuum chamber 10 during the variable diameter transport process of the fluid through the conical cavity 8, which reduces the heat loss to the outside through the conversion head body 1 and effectively prevents the fluid from freezing due to excessively low temperature.

[0025] As an embodiment of this utility model, the end of the conical cavity 8 with a larger radius is connected to the first threaded hole 5, and the end of the conical cavity 8 with a smaller radius is connected to the second threaded hole 9. When the fluid enters the conical cavity 8 from the first threaded hole 5, as the radius of the conical cavity 8 gradually decreases, the cross-sectional area of ​​the fluid decreases, the flow velocity gradually increases, and the pressure gradually decreases, thereby smoothly transitioning to the second threaded hole 9 and ensuring the smooth flow of the fluid.

[0026] As an embodiment of this utility model, the cross-section of the connecting block 2 is a regular hexagon. When installing or disassembling the adapter, the wrench can firmly clamp the regular hexagonal connecting block 2, and the adapter can be tightened or loosened by rotating the connecting block 2, making the operation more convenient and labor-saving.

[0027] As one embodiment of this utility model, the converter body 1 is further made of metal. The lead-free copper converter body 1 maintains structural stability due to its own strength when subjected to fluid pressure within the pipeline and the effects of the external environment. Its corrosion resistance allows it to adapt to various fluid media, reducing the risk of leakage due to corrosion.

[0028] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
