Description

Technical Field

[0001] This utility model relates to the field of three-way structure technology, and more specifically, to a three-way structure. Background Technology

[0002] Currently, tee fittings are key components for achieving fluid or gas diversion. In related technologies, after fluid enters the tee fitting through the inlet, there is an uneven flow of fluid from the two outlets, leading to uneven fluid distribution in the system and affecting system performance. Utility Model Content

[0003] The main purpose of this invention is to provide a three-way structure to solve the problem of uneven drainage from the two drain ports of a three-way fitting in related technologies.

[0004] To achieve the above objectives, this utility model provides a three-way structure, comprising: a three-way body having an inlet, two outlets, and a connecting cavity, wherein the inlet is connected to the two outlets through the connecting cavity; and a flow-dividing structure disposed within the connecting cavity, the flow-dividing structure being disposed opposite to the inlet, and the two outlets being located on opposite sides of the flow-dividing structure; wherein the flow-dividing structure has two guiding surfaces, the two guiding surfaces being disposed one-to-one with the two outlets, and each guiding surface and its oppositely disposed form at least a portion of the cavity wall of the connecting cavity enclosing a flow-dividing space, the inlet being connected to the outlet corresponding to the guiding surface through the flow-dividing space.

[0005] By applying the technical solution of this utility model, the diversion structure has two guiding surfaces, and these two guiding surfaces are arranged one-to-one with the two drain ports, thus ensuring that the fluid entering from the inlet can be effectively and uniformly guided to the two drain ports. This arrangement of the guiding surfaces promotes stable laminar flow, reduces turbulence, and thereby reduces energy loss and pressure drop at bends. This results in a more balanced distribution of fluid within the two drain ports, reducing flow distribution unevenness to within ±3%, thus solving the problem of uneven drainage from the two drain ports in related technologies. Simultaneously, because each guiding surface and its corresponding connecting cavity partially form a guiding space, it not only improves the flow efficiency of the fluid passing through the three-way structure but also effectively reduces fluid impact force, minimizing pipe vibration and noise caused by violent collisions of the fluid within the cavity.

[0006] Furthermore, along the flow direction of the medium within each guide space, the cross-sectional area of ​​the guide space gradually decreases. As the cross-sectional area of ​​the guide space gradually shrinks, the fluid must adapt to the increasingly narrow space when passing through this region. This leads to a gradual increase in fluid velocity. According to Bernoulli's principle, the increase in fluid velocity is accompanied by a decrease in static pressure. The aforementioned tapering design enables the fluid to accelerate near the drain outlet, facilitating efficient kinetic energy conversion and ensuring that the fluid enters the downstream pipeline uniformly with a higher energy state, thereby improving the overall system transmission efficiency. Simultaneously, the tapering guide space not only allows for fine-tuning of the flow rate but also effectively suppresses turbulence, helping to maintain smooth fluid flow, reducing mutual interference and energy loss between fluids, lowering noise and vibration caused by turbulence, and improving system stability and service life.

[0007] Furthermore, the flow-dividing structure also features an arc-shaped surface, with the two guide surfaces connected by this surface, which bulges towards the inlet. The geometry of the arc-shaped surface provides a smooth transition path for the fluid from the inlet to the guide surfaces, avoiding sudden disturbances from sharp or right-angled boundaries. This promotes stable laminar flow rather than turbulent flow, reducing energy loss and pressure drop during turning. It ensures the fluid is evenly distributed across the two guide surfaces with minimal resistance loss before reaching the outlet. Simultaneously, the concave-convex shape of the arc-shaped surface facing the inlet acts as a buffer when the fluid enters the tee body, reducing the direct impact of the fluid on the guide surfaces and minimizing the formation of local high-pressure zones. This reduces the impact force of the fluid on the structure and extends the service life of the equipment.

[0008] Furthermore, each guide surface is inclined relative to the neutral surface S of the tee body, with an included angle A between two guide surfaces, satisfying the condition: 11° ≤ A ≤ 13°. The inclination of the guide surfaces and the selection of a specific included angle A (11° to 13°) effectively guide the fluid along the optimal path and distribute it evenly to the two outlets. This angle setting is carefully calculated to balance the fluid distribution ratio at each outlet while reducing fluid resistance and vortex generation at corners. Simultaneously, the precise control of included angle A (11° to 13°) in conjunction with the inclination of the guide surfaces significantly improves the dynamic performance of the fluid in the tee structure. This configuration utilizes the Bernoulli effect in fluid mechanics, i.e., the relationship between fluid velocity and static pressure, achieving efficient fluid energy conversion by controlling the acceleration and deceleration of the fluid within the guide space 22.

[0009] Furthermore, the longitudinal section of the flow-diverting structure is triangular, with the base of the triangle connected to the wall of the connecting cavity and the apex of the triangle facing the inlet; alternatively, the longitudinal section of the flow-diverting structure is trapezoidal, with the lower base of the trapezoid connected to the wall of the connecting cavity and the upper base facing the inlet. The triangular or trapezoidal longitudinal section shape allows the geometric configuration of the flow-diverting structure to effectively utilize the natural flow tendency of the fluid, effectively improving the dynamic stability of the fluid within the connecting cavity through its specific geometry. Simultaneously, the triangular or trapezoidal longitudinal section design of the flow-diverting structure, by guiding the fluid to flow naturally and uniformly, combined with fluid dynamics optimization, significantly improves the efficiency and stability of fluid transport.

[0010] Furthermore, the longitudinal section of the diversion structure is a combination of a trapezoid and a semicircle. The lower base of the trapezoid connects to the wall of the connecting cavity, and the upper base connects to the plane of the semicircle. The semicircular surface faces the inlet. This orientation of the semicircle towards the inlet provides a smooth transition area for the incoming fluid, facilitating a smooth transition from direct flow to lateral flow and avoiding direct impact from the upper base of the trapezoid, thus reducing turbulence within the fluid. Simultaneously, the trapezoidal structure ensures uniform fluid distribution within the channel. The connection between the lower base and the wall of the connecting cavity provides sufficient space for the fluid to gradually adapt to changes in direction, while the connection between the upper base and the semicircular plane further guides the fluid to flow smoothly and evenly towards the drains on both sides, enhancing the uniformity of fluid distribution and system stability.

[0011] Furthermore, the length L of the lower base of the trapezoid is greater than or equal to 4.5 mm and less than or equal to 5 mm; and / or, the height H of the flow-dividing structure is greater than or equal to 25 mm and less than or equal to 35 mm; and / or, the radius of the semicircle is greater than or equal to 1.0 mm and less than or equal to 2.0 mm. The precise setting of the lower base length L (4.5 mm to 5 mm) and the height H of the flow-dividing structure (25 mm to 35 mm) directly affects the distribution and flow process of the fluid in the guide structure. A longer lower base provides a larger contact area, allowing the fluid to be more evenly dispersed when entering the guide space, thereby reducing fluid impact and turbulence generation. An appropriate height range ensures that the fluid has sufficient space for turning and distribution, which in turn helps optimize fluid dynamics and ensures efficient energy management and conversion in the three-way structure. Simultaneously, the setting of the semicircular radius (1.0 mm to 2.0 mm) is crucial for the overall strength and manufacturing process of the three-way structure, helping to enhance the structural strength of the flow-dividing structure's edges while ensuring a smooth fluid transition, preventing deformation or damage under long-term fluid impact.

[0012] Furthermore, the flow divider structure connects to the cavity wall forming the connecting cavity on both sides along its length. The orthographic projection of the flow divider structure within the inlet divides the inlet's cross-section into two semicircles of equal area. This uniform division of the inlet's cross-section into two equal semicircular regions ensures that regardless of pressure variations, the fluid is uniformly guided to both outlets upon entering the tee structure. Simultaneously, this design minimizes flow distribution deviations from a fluid dynamics perspective, allowing each fluid stream to enter the subsequent pipe at nearly identical velocity and pressure.

[0013] Furthermore, the flow-dividing structure is symmetrically arranged about the neutral plane S of the tee body. This symmetrical arrangement ensures that the fluid, after entering the tee body, is evenly distributed along the flow channels on both sides of the neutral plane S. This helps balance the pressure and velocity of the fluid on both sides, reduces irregular flow at corners, and avoids uneven distribution caused by excessive fluid on one side. This ensures consistent outlet velocity and pressure at both drain ports, improving fluid transfer efficiency and overall system performance. Simultaneously, this arrangement also enhances the structural stability of the flow-dividing structure and the entire tee body.

[0014] Furthermore, the tee body includes: a main body having a connecting cavity, with a flow-diverting structure disposed within the main body; an inlet pipe section connected to the main body, with an inlet formed at the location where the connecting cavity connects to the inlet pipe section; and two outlet pipe sections connected to the main body, with outlets formed at the locations where the connecting cavity connects to each outlet pipe section. The tee body is a one-piece molded structure. Compared to traditional assembly methods, this one-piece molding design significantly improves the overall structural strength of the tee body. Specifically, during precision casting or injection molding, the material is formed in one step within the mold, resulting in a denser internal structure without seams or weld marks. This not only reduces stress concentration caused by thermal expansion and contraction of the material but also eliminates the risk of leakage that may occur at welds or adhesive joints, greatly improving the durability of the device and its sealing reliability under working conditions.

[0025] To address the problem of uneven drainage from the two drain ports of a tee fitting in related technologies, this application provides a tee structure.

[0026] Example 1

[0027] like Figures 1 to 3 As shown, the three-way structure includes a three-way body 10 and a diversion structure 20. The three-way body 10 has an inlet 11, two outlets 12, and a connecting cavity 13. The inlet 11 is connected to the two outlets 12 through the connecting cavity 13. The diversion structure 20 is disposed within the connecting cavity 13, and is positioned opposite to the inlet 11. The two outlets 12 are located on opposite sides of the diversion structure 20. The diversion structure 20 has two guide surfaces 21, which are correspondingly arranged with the two outlets 12. Each guide surface 21 and its opposite form at least a portion of the cavity wall of the connecting cavity 13, forming a guide space 22. The inlet 11 is connected to the outlet 12 corresponding to the guide surface 21 through the guide space 22.

[0028] By applying the technical solution of this embodiment, since the diversion structure 20 has two guiding surfaces 21, and the two guiding surfaces 21 are correspondingly arranged with the two drain ports 12, it is ensured that the fluid entering from the inlet 11 can be effectively and uniformly guided into the two drain ports 12. In this way, the above-mentioned arrangement of the guiding surfaces 21 promotes the formation of stable laminar flow of fluid, reduces the occurrence of turbulence, thereby reducing the energy loss and pressure drop of fluid at the bend, making the distribution of fluid in the two drain ports 12 more balanced, and the flow distribution unevenness can be reduced to within ±3%, thus solving the problem of uneven drainage of the two drain ports of the tee fitting in the related art. At the same time, since each guiding surface 21 and part of the cavity wall of its corresponding connecting cavity 13 form a guiding space 22, it not only improves the flow efficiency of fluid when passing through the tee structure, but also effectively reduces the fluid impact force, and reduces the pipe vibration and noise caused by the violent collision of fluid in the cavity.

[0029] It should be noted that the diversion structure 20 is positioned opposite to the inlet 11, meaning that the diversion structure 20 is positioned towards the inlet 11 to ensure that the fluid entering from the inlet 11 can be diverted by the diversion structure 20 and discharged from the two outlets 12.

[0030] In this embodiment, the cross-sectional area of ​​each flow guide space 22 gradually decreases along the flow direction of the medium within each flow guide space 22. As the cross-sectional area of ​​the flow guide space 22 gradually decreases, the fluid must adapt to the increasingly narrow space as it passes through this area. This leads to a gradual increase in fluid velocity. According to Bernoulli's principle, the increase in fluid velocity is accompanied by a decrease in static pressure. This tapering design allows the fluid to accelerate near the drain port 12, facilitating efficient kinetic energy conversion and ensuring that the fluid enters the downstream pipeline uniformly with a higher energy state, thereby improving the overall system transmission efficiency. Simultaneously, the tapering flow guide space 22 not only finely regulates the flow rate but also effectively suppresses turbulence, helping to maintain smooth fluid flow, reducing mutual interference and energy loss between fluids, lowering noise and vibration caused by turbulence, and improving the system's stability and service life.

[0031] like Figures 1 to 3As shown, the flow-dividing structure 20 also has an arc-shaped surface 23, through which the two guide surfaces 21 are connected. The arc-shaped surface 23 protrudes towards the inlet 11. Thus, the geometry of the arc-shaped surface 23 provides a smooth transition path for the fluid from the inlet 11 to the guide surface 21, avoiding sudden disturbances from sharp or right-angled boundaries. This facilitates stable laminar flow rather than turbulent flow, reducing energy loss and pressure drop during turning. It ensures the fluid is evenly distributed across the two guide surfaces 21 with minimal resistance loss, ultimately reaching the outlet 12. Simultaneously, the concave-convex shape of the arc-shaped surface 23 facing the inlet 11 acts as a buffer when the fluid enters the tee body 10, reducing the direct impact of the fluid on the guide surface 21, decreasing the formation of local high-pressure zones, and thus reducing the impact force of the fluid on the structure, extending the service life of the equipment.

[0032] In this embodiment, the arc-shaped surface 23 cooperates with the two guide surfaces 21, which helps the fluid to be evenly distributed on the two guide surfaces 21. Even under high flow rate conditions, it can maintain good flow uniformity and stability, reduce flow distribution unevenness, and improve the overall system efficiency.

[0033] It should be noted that the arc-shaped surface 23 protruding towards the liquid inlet 11 means that the center of the arc-shaped surface 23 is located on the side away from or away from the liquid inlet 11.

[0034] Optionally, each guide surface 21 is inclined relative to the neutral surface S of the tee body 10, with an included angle A between two guide surfaces 21, satisfying 11°≤A≤13°. This inclination of the guide surfaces 21 and the selection of a specific included angle A (11° to 13°) effectively guides the fluid along an optimal path to be evenly distributed to the two drain ports 12. This angle setting is carefully calculated to balance the fluid distribution ratio at each outlet while reducing fluid resistance and vortex generation at corners. Simultaneously, the precise control of the included angle A (11° to 13°) in conjunction with the inclination of the guide surfaces 21 significantly improves the dynamic performance of the fluid in the tee structure. This configuration utilizes the Bernoulli effect in fluid mechanics, i.e., the relationship between fluid velocity and static pressure, achieving efficient fluid energy conversion by controlling the acceleration and deceleration of the fluid within the guide space 22.

[0035] In this embodiment, each guide surface 21 is inclined relative to the neutral surface S of the tee body 10, and the two guide surfaces 21 are set at an angle A of 12°. This arrangement ensures that the fluid naturally flows along the guiding direction of the V-shaped structure when it reaches the guide surface 21, avoiding energy loss caused by fluid impact and rebound, and ensuring a more uniform fluid distribution in both directions. Simultaneously, the inclined guide surface 21 helps eliminate fluid separation, preventing bubbles or particles from depositing at the turning point, thereby avoiding the risk of blockage and improving the overall operating efficiency and reliability of the system.

[0036] It should be noted that the value of the included angle A is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the included angle A can be 11.5°, 11.8°, 12.5°, or 12.8°.

[0037] Optionally, the longitudinal section of the flow-diverting structure 20 is triangular, with the base of the triangle connected to the wall of the connecting cavity 13 and the apex of the triangle facing the inlet 11; or, the longitudinal section of the flow-diverting structure 20 is trapezoidal, with the lower base of the trapezoid connected to the wall of the connecting cavity 13 and the upper base of the trapezoid facing the inlet 11. In this way, the triangular or trapezoidal longitudinal section shape allows the geometric configuration of the flow-diverting structure 20 to effectively utilize the natural flow tendency of the fluid, effectively improving the dynamic stability of the fluid within the connecting cavity 13 through its specific geometry. Simultaneously, the triangular or trapezoidal longitudinal section design of the flow-diverting structure 20, by guiding the fluid to flow naturally and uniformly, combined with fluid dynamics optimization, significantly improves the efficiency and stability of fluid transport.

[0038] In this embodiment, the flow-diverting structure 20 is connected to the cavity wall forming the connecting cavity 13 on both sides along its length. The longitudinal section of the flow-diverting structure 20 is a combination of a trapezoid and a semicircle. The lower base of the trapezoid is connected to the cavity wall of the connecting cavity 13, and the upper base of the trapezoid is connected to the plane of the semicircle. The semicircular surface of the semicircle faces the inlet 11. This arrangement of the semicircular surface facing the inlet 11 provides a smooth transition area for the incoming fluid, facilitating a smooth transition from direct flow to lateral flow, avoiding direct impact of the fluid on the upper base of the trapezoid, and reducing turbulence within the fluid. Simultaneously, the use of the trapezoidal structure ensures uniform fluid distribution within the channel. The connection between the lower base and the cavity wall of the connecting cavity 13 provides sufficient space for the fluid to gradually adapt to changes in direction, while the connection between the upper base and the semicircular plane further guides the fluid to flow smoothly and evenly to the outlets 12 on both sides, enhancing the uniformity of fluid distribution and system stability.

[0039] Specifically, the combined graphic design integrates the guiding advantages of trapezoids with the smooth fluid handling capabilities of semicircles, significantly improving the dynamic efficiency of the fluid in the three-way structure. The use of semicircular surfaces particularly helps reduce boundary layer separation and energy loss at turning points. The gradient structure of the trapezoid ensures that the fluid can pass through the guide space 22 with minimal pressure drop. This not only improves the fluid transmission efficiency but also reduces the energy demand on the fluid, thereby reducing the overall system energy consumption and extending the equipment's service life. Simultaneously, because the fluid maintains a relatively stable flow state when passing through the combined graphic, fluid impact and turbulence are reduced, thus lowering the noise and vibration levels within the system.

[0040] Optionally, the length L of the lower base of the trapezoid is greater than or equal to 4.5 mm and less than or equal to 5 mm; and / or, the height H of the flow-dividing structure 20 is greater than or equal to 25 mm and less than or equal to 35 mm; and / or, the radius of the semicircle is greater than or equal to 1.0 mm and less than or equal to 2.0 mm. Thus, the precise setting of the lower base length L (4.5 mm to 5 mm) of the trapezoid and the height H (25 mm to 35 mm) of the flow-dividing structure 20 directly affects the distribution and flow process of the fluid in the flow-guiding structure. A longer lower base provides a larger contact area, allowing the fluid to be more evenly dispersed when entering the flow-guiding space, thereby reducing fluid impact and turbulence generation. An appropriate height range ensures that the fluid has sufficient space for turning and distribution, which in turn helps optimize fluid dynamics characteristics and ensures efficient energy management and conversion of the fluid in the three-way structure. Meanwhile, the setting of the semi-circular radius (1.0mm to 2.0mm) is crucial to the overall strength of the tee structure and the realization of the processing technology. It helps to enhance the structural strength of the flow divider edge while ensuring a smooth fluid transition, and avoids deformation or damage under long-term fluid impact.

[0041] In this embodiment, the length L of the lower base of the trapezoid is 4.8 mm, and the height H of the flow splitting structure 20 is 30 mm. The radius of the semicircle is 1.5 mm. Thus, these specific parameter settings not only optimize the dynamic performance of the fluid in the tee structure but also improve the strength and machining accuracy of the structure.

[0042] It should be noted that the value of the length L of the lower base of the trapezoid is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the length L of the lower base of the trapezoid is 4.8mm.

[0043] It should be noted that the height H of the diversion structure 20 is not limited to this value and can be adjusted according to the working conditions and usage requirements. Optionally, the height H of the diversion structure 20 is 28mm or 32mm.

[0044] It should be noted that the radius of the semicircle is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the radius of the semicircle can be 1.2mm or 1.8mm.

[0045] Optionally, the orthographic projection of the flow divider 20 within the inlet 11 divides the cross-section of the inlet 11 into two semicircles of equal area. This ensures that the cross-section of the inlet 11 is uniformly divided into two equal semicircular regions, regardless of pressure variations, ensuring that the fluid is uniformly guided to the two outlets 12 upon entering the tee structure. Simultaneously, this arrangement minimizes flow distribution deviations from a fluid dynamics perspective, allowing each fluid stream to enter the subsequent pipe at nearly the same velocity and pressure.

[0046] In this embodiment, by dividing the cross-section of the inlet 11 into two semicircles of equal area, the fluid can naturally flow along the preset flow channel when it encounters the diversion structure 20, without undergoing complex turning or sudden cross-sectional changes. This design reduces the frictional resistance of the fluid at the turning point, avoids unnecessary energy loss, and also reduces eddies and pressure drops within the fluid.

[0047] Optionally, the flow-dividing structure 20 is symmetrically arranged about the neutral plane S of the tee body 10. This symmetrical arrangement ensures that the fluid, after entering the tee body 10, is evenly distributed along the flow channels on both sides of the neutral plane S. This helps balance the pressure and velocity of the fluid on both sides, reduces irregular flow at corners, and avoids uneven distribution caused by excessive fluid on one side. This ensures consistent outlet velocity and pressure at the two drain ports 12, improving fluid transfer efficiency and overall system performance. Furthermore, this arrangement enhances the structural stability of the flow-dividing structure 20 and the entire tee body 10.

[0048] like Figures 1 to 3As shown, the tee body 10 includes a body section 14, an inlet pipe section 15, and two outlet pipe sections 16. The body section 14 has a connecting cavity 13, and a diversion structure 20 is disposed within the body section 14. The inlet pipe section 15 is connected to the body section 14, and an inlet port 11 is formed at the position where the connecting cavity 13 connects to the inlet pipe section 15. The two outlet pipe sections 16 are connected to the body section 14, and outlet ports 12 are formed at the positions where the connecting cavity 13 connects to each outlet pipe section 16. The tee body 10 is a one-piece molded structure. This one-piece molding design significantly improves the overall structural strength of the tee body 10 compared to traditional assembly methods. Specifically, during precision casting or injection molding, the material is formed in one step within the mold, resulting in a denser internal structure without seams or weld marks. This not only reduces stress concentration caused by thermal expansion and contraction of the material but also eliminates the risk of leakage that may occur at welds or adhesive joints, greatly improving the durability of the device and the sealing reliability under working conditions.

[0049] Example 2

[0050] The difference between the three-way structure in Example 2 and Example 1 is that the shape of the longitudinal section of the diversion structure 20 is different.

[0051] In this embodiment, the longitudinal section of the diversion structure 20 is triangular, with the base of the triangle connected to the cavity wall of the connecting cavity 13, and the apex of the triangle facing the inlet 11. This design, with the apex facing the inlet 11, allows the fluid to be naturally guided to the wider base when it encounters the diversion structure 20, and then flows evenly along the inclined surfaces (guide surfaces 21) on both sides to the two outlets 12. This process reduces fluid impact and rebound, lowering energy consumption. In particular, the apex of the triangle effectively divides the mainstream fluid into two sub-fluids, thereby achieving efficient energy conversion and diversion transmission.

[0052] Example 3

[0053] The difference between the three-way structure in Example 3 and Example 1 is that the shape of the longitudinal section of the diversion structure 20 is different.

[0054] In this embodiment, the longitudinal section of the flow splitting structure 20 is trapezoidal, with the lower base of the trapezoid connected to the cavity wall of the connecting cavity 13, and the upper base of the trapezoid facing the inlet 11. This larger lower base area of ​​the trapezoid provides more contact points, facilitating a smooth transition of the fluid in the initial stage, reducing turbulence formation, and consequently lowering vibration and noise levels within the system. This geometric optimization also reduces fluid accumulation inside the tee, avoiding the risk of impurity deposition and blockage, thereby reducing maintenance requirements and costs, and enhancing system reliability.

[0055] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0056] Because the flow-dividing structure has two guiding surfaces, and these two guiding surfaces are corresponding one-to-one with the two drain ports, it ensures that the fluid entering from the inlet can be effectively and evenly guided into the two drain ports. This arrangement of the guiding surfaces promotes stable laminar flow, reduces turbulence, and thus reduces energy loss and pressure drop at bends. This results in a more balanced distribution of fluid within the two drain ports, reducing flow distribution unevenness to within ±3%, thereby solving the problem of uneven drainage from the two drain ports in related technologies. Simultaneously, because each guiding surface forms a guiding space with a portion of the wall of its corresponding connecting cavity, it not only improves the flow efficiency of the fluid passing through the tee structure but also effectively reduces fluid impact force, minimizing pipe vibration and noise caused by violent collisions of the fluid within the cavity.
