Description

Technical Field

[0001] This application relates to the technical field of water distribution devices, and in particular to a dual-chamber, triple-insulated water distribution control unit. Background Technology

[0002] The market for manifolds is currently developing well. With the increasing demand for heating, its market potential is significant, and its application is gradually expanding in high-end residences and independent heating systems in southern regions. In terms of products, it is developing towards energy conservation and intelligence, with increasingly rich functions to meet the needs of different users.

[0003] Manifolds are widely used in underfloor heating, central air conditioning, industrial circulating water systems, and other fields. In underfloor heating, they are used to centralize and distribute hot water to various areas, playing a role in zoning control. Each branch is equipped with an independent actuator to control opening and closing, thereby regulating the flow and temperature of each area. Its working principle is to introduce fluid (hot water, cold water, or other media) through the main pipe, and then distribute the fluid evenly to each loop through the branch pipes. At the same time, the fluid from each loop is collected and returned to the main pipe through the collection end.

[0004] However, traditional manifolds mostly adopt a one-piece casting or molding structure with a fixed number of branches. This requires users to select different models with different numbers of branches based on the actual area to be used, which not only increases the costs of mold development, manufacturing, and inventory management, but also limits the versatility and flexibility of the product. In addition, the branch outlets of traditional manifolds are usually arranged in a single direction or location, making it difficult to adapt to the needs of complex installation environments or special application scenarios, such as space-constrained situations or multi-directional pipe layouts, further limiting their application scope. Therefore, there is an urgent need for a new type of manifold with a flexible structure, modular combination, and strong adaptability to solve the above problems. Summary of the Invention

[0005] To enable the water distribution unit to adapt to different installation environments and special application scenarios, a dual-chamber, triple-insulated water distribution control unit is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: A dual-cavity, triple-insulated water distribution control unit includes several connecting screws and water distribution bodies. Each water distribution body has several connecting holes along the installation direction of the connecting screws. The connecting screws pass through the connecting holes on the water distribution bodies in sequence and are connected to nuts. Adjacent water distribution bodies fit together. Each water distribution body has an installation hole communicating with its internal space. The outer wall of each water distribution body has a first water distribution hole and a second water distribution hole axially perpendicular to the installation hole. The first water distribution hole and the second water distribution hole are located on different water distribution bodies.

[0007] By adopting the above technical solution, the number of branches of the water manifold can be adjusted by increasing or decreasing the number of water distribution bodies. Each water distribution body has two outlet pipe methods, and the water distribution body can be installed at any of the four angles, making the pipeline layout more flexible. In application scenarios where the installation space is narrow, the height is limited, or multiple directions of pipe connection are required, the most reasonable pipe connection direction can be selected according to the site conditions, overcoming the limitation of traditional water manifolds having only one outlet direction.

[0008] Preferably, the water distribution body has an inner insulation cavity and an outer insulation cavity respectively opened along its own axial direction. The inner insulation cavity encloses the internal space of the water distribution body, and the outer insulation cavity encloses the inner insulation cavity.

[0009] By adopting the above technical solution, the inner insulation cavity encloses the internal space of the water distributor, and the outer insulation cavity encloses the inner insulation cavity. The cavity sandwich structure provides insulation. The two insulation cavities effectively lock the heat of the hot water flowing through the water distributor into the internal space of the main body of the water distributor, achieving the insulation effect. This not only avoids the waste of heat, but also prevents the outward heat from condensing with the outside air, thus achieving the anti-condensation and anti-condensation effects.

[0010] Preferably, the outer wall of the water distribution body is covered with a water distribution body insulation component.

[0011] By adopting the above technical solution, the insulation component covering the outer wall of the water distribution body can reduce heat loss and prevent the dissipated heat from condensing with the outside air, thus achieving the effects of preventing condensation and preventing condensation.

[0012] Preferably, it also includes a connecting frame, on which a connecting bracket connected to the end of the connecting screw is fixed. One side of the connecting bracket is provided with a water supply pipe that communicates with the internal space of the water distribution body, and the side of the connecting bracket with the water supply pipe is covered with a side insulation component.

[0013] By adopting the above technical solution, the side insulation component can insulate the connection between the water supply pipe and the water distribution body, preventing the heat dissipated from the inside and outside of the water distribution body from being dissipated through the connection, and ensuring that the risk of condensation is reduced when the water supply pipe supplies water to the internal space of the water distribution body.

[0014] Preferably, the two sides of the water divider are respectively provided with a main bonding surface and a bonded surface, and an annular sealing groove is provided on the main bonding surface, and the main bonding surface and the bonded surface of adjacent water dividers are bonded together.

[0015] By adopting the above technical solution, the side of one water distribution body with a sealing groove abuts against the side of another water distribution body without a sealing groove. When the main contact surface and the contact surface are in contact, the sealing groove forms an annular sealing strip. Even if there are slight unevennesses on the connection surface between adjacent water distribution bodies, it can accommodate potential leakage fluid, improve the sealing performance when adjacent water distribution bodies are connected, and reduce energy consumption and system failure.

[0016] Preferably, the main bonding surface is provided with a plurality of first positioning ribs and first positioning holes, and the bonding surface is provided with second positioning holes coaxial with the first positioning ribs and second positioning ribs coaxial with the first positioning holes, and the second positioning holes are for the insertion of the first positioning ribs, and the first positioning holes are for the insertion of the second positioning ribs.

[0017] By adopting the above technical solution, during installation, adjacent water distribution bodies will only be fully fitted when the main mating surface with the sealing groove comes into contact with the mating surface without the sealing groove. This requires that the main mating surface be installed in a matching pair with the mating surface. If the installation direction is incorrect (such as the two main mating surfaces being opposite each other), the positioning ribs cannot be inserted, and the adjacent water distribution bodies cannot be fully fitted. This provides a foolproof function and avoids sealing failure or leakage.

[0018] Preferably, the first water distribution hole and the second water distribution hole are respectively provided with a first connector and a second connector, and the first connector and the second connector are respectively embedded with metal parts between them and the inner wall of the mounting hole.

[0019] By adopting the above technical solution, the first connector and the second connector are respectively connected to the external connecting pipe. The embedded metal parts can increase the torsional resistance at the connection, enhance the structural strength and stability of the connection between the first connector and the second connector, and thus improve the overall performance and service life of the manifold.

[0020] Preferably, a support member is fixedly provided inside the water distribution body, and the end of the support member is connected to one end of the first connecting member located inside the water distribution body.

[0021] By adopting the above technical solution, the support member fixes one end of the first connector inside the water distribution body, preventing it from bending or shifting under high pressure fluid. Under long-term cyclic load, the support member disperses stress, avoids fatigue cracking at the end of the first connector, and improves the durability of the system.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The single-line water distribution body has two outlet pipe methods, and the water distribution body can be installed at any of the four angles, making the pipeline layout more flexible and adaptable to the needs of complex installation environments or special application scenarios, such as space-constrained and multi-directional pipe laying, thus expanding the application range. 2. Two insulation chambers are combined with the water distribution body insulation component to achieve a three-layer insulation effect for the water distribution body. This effectively locks the heat of the hot water flowing through the water distribution body into the internal space of the water distributor body, preventing the heat from dissipating outward from condensing with the outside air. This achieves both anti-condensation and anti-condensation effects. 3. The embedded metal parts can increase the torsional resistance at the connection and enhance the structural strength and stability of the connection between the first and second connectors.

Detailed implementation method: The following section provides a more detailed description, in conjunction with the accompanying diagrams: As attached Figure 1 and attached Figure 2As shown, a dual-cavity, three-insulated water distribution control unit is a water collector integral structure, including a connecting frame 1, a connecting screw 2, and a water distribution body 3. There are two connecting frames 1 here, and connecting brackets 11 are fixedly connected to both ends of the connecting frame 1. The connecting brackets 11 on the two connecting frames 1 are aligned with each other, and water pipes 111 for water inlet or outlet are fixedly connected to the four connecting brackets 11 respectively.

[0024] The main body of the connecting screw 2 is usually made of metal, which has a certain strength and rigidity. The outer circumference of the connecting screw 2 is threaded. There are two sets of connecting screws 2 here, and each set connects four screws 2. The two sets of connecting screws 2 are respectively aligned with the connecting brackets 11 at the ends of the two connecting frames 1, and the two ends of the connecting screw 2 are fixedly connected to the connecting brackets 11 by nuts, so that the connecting brackets 11 on the two connecting frames 1 support the two sets of connecting screws 2 respectively.

[0025] Water distribution body 3 is usually made of high-strength plastic, such as reinforced PA66, to ensure that it will not be easily corroded by fluids during long-term use. The shape of water distribution body 3 is square or circular. Several water distribution bodies 3 are provided here. Adjacent water distribution bodies 3 are fitted together. The water distribution body 3 has an internal space for fluid flow. The internal spaces of adjacent water distribution bodies 3 are connected and connected to the water supply pipe 111. Four through-holes 31 are opened on the water distribution body 3 along the installation direction of the connecting screw 2. The diameter of the connecting hole 31 is adapted to the screw. The connecting screw 2 passes through the connecting hole 31 to provide support for several water distribution bodies 3. The combination logic of the connecting screw 2 and the water distribution body 3 is that the connecting screw 2 passes through the connecting hole 31 of the water distribution body 3 in sequence and is then tightened with nuts to make multiple water distribution bodies 3 tightly connected together to form an integrated water distribution manifold.

[0026] As attached Figure 3 and attached Figure 4 As shown, the water distribution body 3 has a through mounting hole 32 perpendicular to its own axis. The mounting hole 32 is connected to the internal space of the water distribution body 3. The outer wall of the water distribution body 3 has a first water distribution hole 33 perpendicular to the mounting hole 32. The outer wall of the water distribution body 3 has a second water distribution hole 34 perpendicular to the mounting hole 32. The second water distribution hole 34 is aligned with the mounting hole 32. The first water distribution hole 33 and the second water distribution hole 34 are located on different water distribution bodies 3. Only a single water distribution hole is opened on a single water distribution body 3.

[0027] The water distribution body 3 is equipped with a first connector 5 and a second connector 6 at the first water distribution hole 33 and the second water distribution hole 34, respectively. The first connector 5 and the second connector 6 are usually water distribution pipes. One end of the first connector 5 and the second connector 6 are connected to the internal space of the water distribution body 3, and the other end of the first connector 5 and the second connector 6 are located outside the water distribution body 3 and are used to connect to external pipes. A metal part 7 is embedded between the first connector 5 and the second connector 6 and the inner wall of the first water distribution hole 33 and the second water distribution hole 34, respectively. The metal part 7 is generally a copper sleeve or a stainless steel sleeve, which can increase the torsional resistance at the connection between the first connector 5 and the second connector 6 and the water distribution body 3, and enhance the connection strength and sealing between the first connector 5 and the second connector 6 and the water distribution body 3.

[0028] As attached Figure 5 As shown, the water distribution body 3 is equipped with a control actuator 4 at the mounting hole 32. The installation angle and number of water distribution bodies 3 with different water distribution directions can be adjusted according to the actual scenario, so that the fluid can be distributed from multiple directions, which can meet the needs of complex installation environment or special application scenario.

[0029] As attached Figure 6 and attached Figure 7 As shown, a support member 8 is integrally formed inside the water distribution body 3, and the end of the support member 8 is connected to the first connecting member 5. Here, the support member 8 is perpendicular to the first connecting member 5. One end of the first connecting member 5 is suspended in the internal space of the water distribution body 3. When fluid flows through the internal space of the water distribution body 3, the support member 8 plays the role of supporting and fixing the first connecting member 5, ensuring the stability of the first connecting member 5 inside the water distribution body 3, and preventing it from being displaced or loosened under the action of fluid pressure.

[0030] The water distribution body 3 has a main contact surface 38 and a contact surface 39 on both sides. The main contact surface 38 and the contact surface 39 of adjacent water distribution bodies 3 are in contact with each other. The water distribution body 3 has an annular sealing groove 381 on the main contact surface 38. The sealing groove 381 is opened on the contact surface of adjacent water distribution bodies 3. The sealing groove 381 is located between the inner insulation cavity 35 and the internal space of the water distribution body 3. When the main contact surface 38 and the contact surface 39 are in contact, the sealing groove 381 forms an annular sealing band. Even if there is a slight unevenness in the connection surface between adjacent water distribution bodies 3, it can accommodate potential leakage fluid. In actual process, a rubber sealing ring is installed in the sealing groove 381. The rubber sealing ring is compressed in the sealing groove 381 to ensure the sealing performance when adjacent water distribution bodies 3 are in contact.

[0031] The water distribution body 3 has four first positioning holes 382 and four first positioning ribs 383 fixed on the main mating surface 38. The water distribution body 3 has four second positioning holes 391 and four second positioning ribs 392 fixed on the mating surface 39. The four first positioning holes 382 are coaxial with the four second positioning ribs 392, and the four second positioning holes 391 are coaxial with the four second positioning ribs 392. When adjacent water distribution bodies 3 are mated together, the four first positioning ribs 383 are inserted into the four second positioning holes 391, and the four second positioning ribs 392 are inserted into the four first positioning holes 382. The main mating surface 38 must be paired with the mating surface 39 for installation. If the installation direction is incorrect (e.g., the two main mating surfaces 38 are opposite each other), the first positioning ribs 383 or the second positioning ribs 392 cannot be inserted, and the adjacent water distribution bodies 3 cannot be fully mated. This provides a foolproof function and avoids sealing failure or leakage.

[0032] The water distribution body 3 has an inner insulation cavity 35 and an outer insulation cavity 36 on both sides along its own axis. Both the inner insulation cavity 35 and the outer insulation cavity 36 are hollow sandwich structures. The inner insulation cavity 35 encloses the internal space of the water distribution body 3, and the outer insulation cavity 36 encloses the inner insulation cavity 35. The arrangement of the inner insulation cavity 35 and the outer insulation cavity 36 can form a double-layer insulation structure, which can effectively lock the heat of the hot water flowing through the water distribution body 3 into the internal space of the water distributor body, achieving a heat preservation effect. This not only avoids the waste of heat, but also prevents the outward heat from condensing with the outside air, thus achieving anti-condensation and anti-condensation effects.

[0033] As attached Figure 8 and attached Figure 9 As shown, the outer wall of the water distribution body 3 is covered with a water distribution body insulation component 37. The water distribution body insulation component 37 is usually an insulation sleeve, made of a material with good insulation performance. By wrapping it around the outer wall of the water distribution body 3, it plays a role in further reducing heat loss. The water distribution body insulation component 37, together with the inner insulation cavity 35 and the outer insulation cavity 36, forms a three-layer insulation structure, which further enhances the insulation effect of the water distribution body 3.

[0034] As attached Figure 1 As shown, a side insulation component 113 covering the water supply pipe 111 is provided on one side of the connecting bracket 11. The side insulation component 113 is usually an insulation sleeve. The side insulation component 113 is used to seal the outer wall of the water supply pipe 111 and the connection between the water supply pipe 111 and the connecting bracket 11 to reduce heat loss. A bracket insulation component 112 is provided on the outer wall of the connecting bracket 11. The bracket insulation component 112 is similar to the water distribution body insulation component 37. It is used to reduce heat loss at the water inlet or outlet pipe inside the connecting bracket 11, reduce condensation at the connection between the water supply pipe 111 and the water distribution body 3, and further improve the insulation performance of the entire water distribution manifold.

[0035] The implementation principle of this embodiment is as follows: Several single-channel water distribution bodies 3 are assembled in series and fit together through connecting screws 2. Users can increase or decrease the number of water distribution bodies 3 according to actual needs (such as heating area). At the same time, users can choose to install water distribution bodies 3 with first water distribution holes 33 or water distribution bodies 3 with second water distribution holes 34 according to the actual single-channel direction. The first water distribution hole 33 distributes water along the axis perpendicular to the mounting hole 32, and the second water distribution hole 34 distributes water along the axis of the mounting hole 32. The two are distributed in different water distribution bodies 3, so that the water distribution direction can be adjusted as needed. The inner insulation cavity 35 of the water distribution body 3 encloses the internal space of the water distribution body 3, the outer insulation cavity 36 encloses the inner insulation cavity 35, and the water distribution body insulation component 37 covers the outer wall of the water distribution body 3. The inner insulation cavity 35, the outer insulation cavity 36 and the water distribution body insulation component 37 together form a three-layer insulation structure, which locks the heat of the fluid in the internal space of the water distribution body 3 and prevents the heat dissipated from condensing with the outside air.

[0036] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
