[0002] In existing water supply piping systems, tee fittings are commonly used to connect water flows in multiple directions. However, existing tee fittings have significant limitations in terms of fixed angles. In scenarios with significant terrain variations or complex installation environments, these fixed-angle tee fittings often cannot be effectively adjusted. This makes it difficult to meet various complex water supply needs during actual installation. This fixed-angle design not only increases installation difficulty but may also lead to problems such as poor water flow or unstable pipe connections, seriously affecting the performance and reliability of the entire water supply system.

Each of the two branch pipe openings of the U-shaped pipe body is provided with a clamping device, which is a ring-shaped plate formed on the branch pipe opening of the U-shaped pipe body. This t-connector has a fixed angle and cannot meet various water supply needs. Utility Model Content

[0004] This utility model provides a tee pipe that meets various water supply needs. By setting a straight pipe connecting part, it realizes multi-angle connection of the ring fitting, meets water supply needs at different angles, and improves applicability.

[0005] A further objective of this invention is to optimize the water flow path, reduce water flow resistance, and prevent water from accumulating inside the pipe by setting the position and angle of the asymmetrical whole and branch pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a three-way pipe that meets various water supply needs, comprising an arc-shaped main pipe, one end of which is a water inlet and the other end is a drain outlet, and a branch pipe is connected to one side of the main pipe, which is located close to the drain outlet; the inner wall of the drain outlet is provided with a connecting part, which is a straight pipe and connected to a ring-shaped fitting, the center of the main pipe is the vertex, and the line connecting the main pipe and the drain outlet forms an angle ranging from 35° to 55°.

[0007] Preferably, the center of the main pipe is the vertex, and the angle formed by the line connecting it to the inlet and outlet is between 125° and 135°, with 135° being the preferred setting. This ensures smooth water flow within the main pipe, reduces resistance at bends, and thus improves water flow efficiency.

[0011] Preferably, the branch pipes are straight pipes. This design ensures the structural stability and durability of the branch pipes, enabling them to withstand water flow of varying pressures and volumes.

[0012] Preferably, the angle between the center of the main pipe (as the vertex) and the lines connecting it to the inlet and branch pipes (as sides) ranges from 80° to 100°, with 90° being the most preferred. This angle ensures optimized water flow path, reduces water flow resistance, and prevents stagnant water from accumulating inside the pipe, thereby improving the efficiency and reliability of the entire system.

[0013] Preferably, a limiting seat is provided near the inner end of the connecting part. The design of the limiting seat ensures that the annular fitting rotates stably within the connecting part, preventing the fitting from shifting or being damaged under the impact of water flow.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In various water supply pipeline systems, such as urban water supply and building water supply and drainage systems, tee fittings are key components for changing the direction of water flow and connecting multiple pipelines. Their performance directly affects the operation of the entire water supply system. Most existing tee fittings adopt a fixed-angle design. This traditional structure reveals significant limitations when facing installation environments with significant terrain undulations and complex internal pipe layouts within buildings. Because the angle cannot be adjusted, installers often need to spend considerable time and effort bending and splicing the pipes to adapt to complex installation requirements. This not only increases construction difficulty and installation costs but also easily leads to localized pipe deformation due to excessive bending, resulting in problems such as poor water flow and reduced sealing at pipe connections. More seriously, the fixed-angle design makes it easy for water flow to form eddies and impacts at bends when passing through the tee fitting, creating significant flow resistance. This not only reduces water supply efficiency but may also lead to unstable pipe connections. Long-term use can even cause pipe loosening and leakage, severely affecting the performance and reliability of the entire water supply system.

[0023] To address the aforementioned problems, this utility model proposes a tee pipe that meets various water supply needs. Through innovative structural design, it effectively solves many drawbacks of traditional tee pipe fittings. The tee pipe uses an arc-shaped main pipe 1 as its basic structure. One end of the main pipe 1 serves as the inlet 1.1, receiving water from the water supply pipe; the other end is the outlet 1.2, the channel through which water flows out of the tee pipe and into the downstream pipe. A branch pipe 2 is connected to one side of the main pipe 1, and the branch pipe 2 is positioned close to the outlet 1.2. This layout fully considers the flow characteristics and distribution requirements of the water.

[0024] The connecting part 1.2.1 on the inner wall of the drain outlet 1.2 is the core structure for multi-angle connections of this tee pipe. The connecting part 1.2.1 is a straight pipe that can connect with the ring fitting 3. This design breaks the limitation of the fixed angle of traditional tee pipe fittings. The ring fitting 3 can rotate and adjust around the straight connecting part 1.2.1 at multiple angles, thus achieving flexible connections with pipes in different directions. Whether facing outdoor water supply projects with complex terrain or indoor water supply and drainage systems with varied pipe layouts, installers can adjust the angle of the ring fitting 3 according to actual needs to perfectly connect the tee pipe with other pipes, meeting water supply requirements at different angles and greatly improving the applicability of the tee pipe.

[0025] Regarding the angle design of the main pipe 1, the R&D team constructed a complex mathematical model through rigorous fluid dynamics calculations, simulated and deduced the water flow state at different angles, and verified it through numerous experiments, ultimately determining a scientifically reasonable angle range. The angle range formed by the center of the main pipe 1 as the vertex and the lines connecting it to the inlet 1.1 and outlet 1.2 as sides was precisely set to 125° - 135°, with 135° being the preferred angle. This angle setting was not arbitrary but fully considered the dynamic characteristics of water flow within the pipe. When water flows into the main pipe 1 from the inlet 1.1, guided by the 135° bending angle, it can smoothly and naturally turn towards the outlet 1.2. Unlike the common right-angle or acute-angle turns in traditional tee fittings, this design greatly reduces the collisions and impacts caused by sudden turns at bends. Without strong collisions, the energy loss of the water flow is reduced, effectively reducing water flow resistance. With this design, water can flow through the T-junction more quickly and stably, ensuring a stable and efficient water supply for the water supply system, whether under low or high flow conditions, and ensuring that water is delivered continuously and smoothly to all stages.

[0026] The tee pipe features an asymmetrical structural design, an innovation that breaks away from the traditional symmetrical form of tee fittings. This asymmetrical structure allows for greater flexibility in spatial layout, better adapting to different installation environments and water flow requirements. In practical applications, whether in narrow pipe shafts, complex corner spaces, or pipe layouts requiring specific routing, the asymmetrical tee pipe, with its unique shape, can cleverly integrate into the installation environment, finding the optimal installation position and angle. This avoids problems caused by space limitations that prevent installation or result in poor installation outcomes, further enhancing the flexibility and applicability of the tee pipe.

[0027] The design of branch pipe 2, positioned on the side of the main pipe 1 near the drain outlet 1.2 along its axis of symmetry, also reflects a deep consideration for optimizing water flow. This layout makes branch pipe 2 more efficient in receiving and distributing water. When water flows within the main pipe 1, its proximity to the drain outlet 1.2 allows for a more natural diversion of the water flow into branch pipe 2 as it approaches the outlet, reducing turbulence and disturbances caused by improper branch pipe 2 placement. Simultaneously, this design effectively reduces resistance within the main pipe 1, resulting in smoother flow between the main pipe 1 and branch pipe 2. Water is also distributed and transmitted more stably through the tee, preventing water accumulation within the pipe and ensuring the stability and efficiency of the entire water supply system.

[0028] This utility model presents a tee pipe that meets various water supply needs. Through a series of innovative designs, including a straight pipe connecting section 1.2.1 enabling multi-angle connections, a scientifically designed angle to optimize water flow paths, an asymmetrical structure to improve applicability, and a rational branch pipe layout 2 to reduce water flow resistance, it fundamentally solves the problems inherent in traditional tee pipe fittings. Whether in complex installation environments or for optimizing water flow transmission performance, this tee pipe demonstrates significant advantages, providing a reliable guarantee for the efficient operation and stable water supply of water supply pipeline systems.

[0029] The design of branch pipe 2 being perpendicular to the main pipe 1 is a scientific layout based on fluid mechanics principles. When water flows from the main pipe 1 to branch pipe 2, the vertical angle makes the change in water flow direction smoother. Compared to an inclined connection, the vertical setting reduces the impact and turbulence during the water flow change. Before entering branch pipe 2, the water maintains a stable flow state within the main pipe 1. Upon contact with the branch pipe 2 interface, due to the vertical angle, the water flow can be split with minimal energy loss, avoiding sudden changes in water flow velocity and pressure fluctuations caused by abrupt angle changes. This design not only makes the water flow output of branch pipe 2 more stable but also effectively reduces the hydraulic losses throughout the entire tee pipe, ensuring the efficient operation of the water supply system. For example, in scenarios where water needs to be supplied to two vertical directions simultaneously, the vertically positioned branch pipe 2 can ensure balanced water flow pressure in each direction, preventing uneven flow distribution from affecting the normal operation of downstream water-using equipment.

[0030] Branch pipe 2, with its straight pipe structure, is a crucial guarantee for the durability and stability of the pipe fittings. The straight pipe design of branch pipe 2 simplifies the manufacturing process, allowing for standardized production that ensures uniform wall thickness and a smooth interior, reducing water flow resistance caused by irregularities in the pipe wall. Simultaneously, the straight pipe structure provides a more uniform stress distribution when subjected to water pressure, effectively coping with the impact of water flow under varying pressures and flow rates. Whether enduring high fluid pressure in a high-pressure water supply system or dealing with water flow impacts in scenarios with large flow fluctuations, branch pipe 2 maintains structural stability and is less prone to deformation or breakage. Furthermore, the straight pipe design facilitates connection with other pipe fittings (such as valves and flow meters), simplifying the installation process, improving construction efficiency, and reducing the risk of leakage due to complex connections.

[0031] In the angle design of the main pipe 1, the included angle formed by the center of the main pipe 1 as the vertex and the line connecting the inlet 1.1 and the branch pipe 2 as the side is set within the range of 80°-100°, with 90° being preferred. This angle selection has been verified through extensive fluid simulation and experiments. When the included angle is 90°, the inlet 1.1, the center of the main pipe 1, and the branch pipe 2 form a right-angle layout. This layout optimizes the water flow path, making the flow trajectory smoother as the water enters the main pipe 1 from the inlet 1.1 and turns to the branch pipe 2. No obvious eddies or stagnant water zones are formed within the main pipe 1, effectively preventing water accumulation. The presence of stagnant water zones can easily lead to the sedimentation of impurities and bacterial growth in the water, affecting water quality; the 90° angle design eliminates this potential hazard. Simultaneously, the optimized water flow path reduces water flow resistance, allowing the water to pass through the tee pipe more efficiently, reducing energy consumption and improving the reliability and economy of the entire water supply system.

[0032] The limiting seat located near the inner end of the connecting part 1.2.1 is a key structure ensuring the stable operation of the annular fitting 3. The limiting seat is typically made of the same material as the main pipe 1, possessing sufficient strength and wear resistance. Its shape is adapted to the inner wall of the connecting part 1.2.1, precisely limiting the rotation range of the annular fitting 3. When the annular fitting 3 rotates within the connecting part 1.2.1 to adjust its angle, the limiting seat prevents excessive rotation or disengagement from the connecting part 1.2.1, ensuring it remains within a safe operating range. Even when subjected to vibration due to water flow impact, the limiting seat maintains the stable position of the annular fitting 3 through physical limiting, preventing loosening of the connection or seal failure due to fitting displacement. This design not only improves the service life of the annular fitting 3 but also enhances the reliability of the tee pipe in dynamic water flow environments, ensuring the safe operation of the water supply system.

[0033] The connection design of the fitting connector 3.1 at one end of the ring-shaped fitting 3 with the drain outlet 1.2 embodies a perfect combination of sealing and flexibility. The fitting connector 3.1 is carefully designed with a straight pipe structure that matches the drain outlet 1.2, achieving a tight fixation through precision manufacturing. This connection is not a simple combination, but rather a result of in-depth consideration of pipe material characteristics and interface shape, utilizing methods such as threaded engagement, precise socketing, flange fastening, or heat fusion to construct a tight barrier between the two. In this way, it ensures the sealing of water flow, nipping potential leaks in the bud. The tight connection between the fitting connector 3.1 and the drain outlet 1.2 also effectively transmits water pressure, ensuring that water flow does not experience turbulence or pressure loss due to interface gaps when passing through the connection point. This further optimizes the hydraulic performance of the tee pipe from the details, making water delivery more efficient and stable.

[0034] The connecting part 3.1, as a straight pipe structure, together with the connecting part 1.2.1, constitutes the rotating mechanism of the annular fitting 3. This double straight pipe design allows the annular fitting 3 to rotate 360° flexibly within the connecting part 1.2.1. Whether connecting pipes to the left, right, or any other angle, the annular fitting 3 can easily achieve this through rotation. In actual installation, installers do not need to replace tee fittings at different angles; they can simply rotate the annular fitting 3 to adapt to different pipe layouts, greatly reducing the types of fittings and inventory costs. At the same time, the flexible rotation function can also compensate for positional deviations during pipe installation to a certain extent, reducing the requirements for installation accuracy and improving construction efficiency, making it particularly suitable for complex internal building piping systems or outdoor pipe network projects with varying terrain.

[0035] In summary, this utility model's tee pipe, through a series of innovations including vertical branch pipe 2, straight pipe structure, precise angle design, limiting seat, and flexible rotating annular fitting 3, comprehensively improves the applicability, flow efficiency, and structural stability of the pipe fitting. These design details work together to not only solve the problems of fixed angles and high flow resistance in traditional tee pipe fittings, but also provide a more efficient and reliable solution for the installation and operation of water supply systems. From optimizing the flow path to achieving multi-angle connections, from improving structural stability to simplifying the installation process, this utility model's tee pipe demonstrates significant technical advantages in the water supply field and has broad application prospects and promotional value.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
