Description

Technical Field

[0001] This utility model relates to a pipe water distribution structure, and more specifically, to a novel water distributor. Background Technology

[0002] Manifolds, as devices used to distribute and control water flow, are widely used in heating systems, underfloor heating systems, irrigation systems, and industrial piping systems. Although manifold technology is relatively mature, some technical difficulties and challenges still exist in practical applications. In complex piping systems, manifolds need to distribute water flow evenly to each branch, but uneven distribution often occurs in practice. For example, some branches may have excessive water flow, resulting in insufficient flow in other branches. Water flow distribution is also affected by factors such as pipe resistance and pressure fluctuations.

[0003] For example, Chinese Patent Publication No. CN207922343U, published on September 28, 2018, is entitled "A Novel Manifold," which includes a manifold body. The manifold body has a manifold inlet chamber with a manifold inlet end and a manifold outlet chamber with a manifold outlet end. The manifold body also has at least one manifold connection end connecting to a pipe-in-pipe. The manifold connection end consists of an inlet outlet end connecting to the manifold inlet chamber and an outlet inlet end connecting to the manifold outlet chamber. A control valve mounting position is provided on the inlet outlet end, and a corresponding control valve is installed on the control valve mounting position. This solution simultaneously functions as a manifold for water distribution and return. Each underfloor heating system only needs one manifold to achieve the function of two traditional manifolds, greatly reducing manufacturing and installation costs. However, in this scheme, the water distribution effect of the distributor is poor. Some branches have a larger flow rate because they are close to the water inlet, while some branches have a smaller flow rate because they are far from the water inlet, resulting in uneven water distribution. Utility Model Content

[0004] This invention overcomes the problem of uneven water distribution in existing water distributors and provides a new type of water distributor. This solution makes the water flow distribution on different branches of the water distributor more uniform and improves the water distribution effect of the water distributor.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A novel water distributor includes a water distribution pipe body with a plurality of water distribution outlets. An arc-shaped guide plate is provided on the inner wall of the water distribution pipe body corresponding to each water distribution outlet. One end of the guide plate is located at the corresponding position of the water distribution outlet, and the other end of the guide plate is inclined along the water inlet direction and located on the side of the water distribution pipe body away from the water distribution outlet. The arc-shaped guide plate convexes towards the water inlet direction. The multiple water distribution outlets on the water distribution pipe body form the input ends of multiple water distribution branches. The arc-shaped guide plate inside the water distribution pipe body serves to guide and intercept the water flow within the water distribution pipe body, allowing the water in the pipe to be intercepted at the location of the water distribution outlet, increasing the water flow at the outlet, thereby ensuring that each water distribution outlet has a greater water flow, thus improving the uniformity of water distribution in each branch of the water distributor and improving the water distribution effect.

[0006] Preferably, the guide plates are symmetrically arranged on the water distribution pipe body, and water passage gaps are provided between the symmetrically distributed guide plates. The symmetrical distribution of the guide plates on the water distribution pipe body improves the interception effect of the guide plates on the water flow; while the intervals between the symmetrically distributed guide plates form water passage gaps, which can ensure that the water flow normally through the water distribution pipe body.

[0007] Preferably, the water distribution pipe includes an inlet, the guide plate has a circular arc surface on the side near the inlet, and the guide plate has a gradually expanding arc surface on the side away from the inlet. The design of the guide plate as an arc on the side near the inlet and as a gradually expanding shape on the other side effectively reduces water flow resistance and energy loss.

[0008] Preferably, the length of the guide plate is negatively correlated with the distance from the guide plate to the inlet. As the length of the guide plate increases, its inclination decreases (leaning towards the horizontal), thus reducing the resistance to water flow within the distribution pipe. Therefore, the farther the guide plate is from the inlet, the shorter its length and the steeper its inclination, resulting in greater resistance to water flow and enabling more water to be intercepted at the distribution outlet, thereby increasing the water flow rate at the distribution outlet.

[0009] Preferably, a water distribution connector is detachably connected to the water distribution port, and a valve assembly is provided on the water distribution pipe body corresponding to the water distribution connector. The valve assembly is used to open and close the water distribution connector at the water distribution port, thereby realizing the on / off state of the water distribution port and adjusting the water distribution effect at different water distribution ports.

[0010] Preferably, the valve assembly includes a valve stem with a valve disc adapted to the water distribution connector at one end near the water distribution port, and a valve seat connected to the other end of the valve stem. The valve seat is fixedly connected to the water distribution pipe body, and a valve switch connected to the valve stem is provided on the valve seat. By operating the valve switch, the valve stem can be moved, thereby causing the valve disc to open or close the water distribution connector, thus controlling the flow of water at the water distribution connector.

[0011] Preferably, the radial dimension of the valve plate is smaller than the water passage gap. The radial dimension of the valve plate needs to be smaller than the water passage gap to prevent interference between the valve plate and the guide plate, which would affect the installation of the guide plate and its flow guiding effect.

[0012] Preferably, the radial dimension of the water distribution pipe is larger than the radial dimension of the water inlet. This larger radial dimension allows for better arrangement of guide plates on the inner wall of the water distribution pipe, and also increases the width of the guide plates to a certain extent, thus improving their flow guiding effect.

[0013] Preferably, the guide plate and the water distribution pipe are detachably connected. This detachable connection not only facilitates later maintenance but also allows for compatibility with water distributors in more types of piping systems.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) the water flow distribution on different branches in the water distributor is more uniform, which improves the water distribution effect of the water distributor; (2) the arc-shaped front end and the gradually expanding rear end design of the guide plate reduce the flow resistance and reduce energy loss; (3) the guide plate adopts a modular design, which is convenient for installation and disassembly and reduces maintenance costs; (4) the modular design and symmetrical layout simplify the internal structure of the water distributor and reduce manufacturing costs.

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] Example 1: As Figures 1 to 5 The illustration shows a novel water distributor, comprising a water distribution pipe body 1 with an inlet 5 and an outlet 6 at its two ends. The middle section of the water distribution pipe body 1 is approximately rectangular. Four sets of water distribution outlets 2 are provided on the water distribution pipe body 1, located below the water distribution pipe body 1 (as shown in the illustration). Corresponding to the positions of some of the water distribution outlets 1, guide plates 3 are provided on the inner wall of the water distribution pipe body 1. The guide plates 3 are curved arcs, with their bottoms located on the openings of the water distribution outlets 2. The top of the guide plate 3 is located at the top of the water distribution pipe body 1 (i.e., away from the water outlet 2). The interior of the water distribution pipe body 1 is a rectangular cavity, and the guide plate 3 is arranged on the vertical cavity wall inside the water distribution pipe body 1, inclined along the water flow direction inside the water distribution pipe body 1. The guide plate 3 has an arc-shaped structure, with its convex surface in the same direction as the water flow inside the water distribution pipe body 1. That is, the concave surface of the guide plate 3 faces the water inlet 5 of the water distribution pipe body 1. When the water flows inside the water distribution pipe body 1, the water flows along the concave surface of the guide plate 3. Since the top of the guide plate 3 extends all the way to the top of the water distribution pipe body 1, the water cannot flow away from the top of the guide plate 3, and can only flow downstream along the width of the guide plate 3. Thus, the guide plate 3 can guide the water flow to the location of the water outlet 2, so that there is more water flow and greater water pressure above the water outlet 2.

[0023] The guide plate 3 is made of high-strength stainless steel, possessing excellent pressure resistance and corrosion resistance. The surface of the guide plate 3 also requires polishing to reduce surface friction resistance. Each water outlet 2 can have one or two sets of guide plates 3. When there is one set of guide plates 3, they are arranged on any vertical side wall of the water distribution pipe 1. Water in the water distribution pipe 1 is guided to the location of the water outlet 2 after passing through the guide plates 3. When there are two sets of guide plates 3, they are arranged on two vertical side walls of the water distribution pipe 1 in a symmetrical distribution. When water flows through the guide plates 3, the guide plates 3 on both sides converge the water towards the location of the water outlet 2. In this embodiment, two sets of guide plates 3 are used for illustration.

[0024] Two sets of guide plates 3 are arranged at intervals on the water distribution pipe body 1, and a water passage gap 4 is formed between the two sets of guide plates 3. The water passage gap 4 allows water to flow through the inside of the water distribution pipe body 1. At the same time, due to the presence of the two sets of guide plates 3, the water passage area of ​​the water passage gap 4 is smaller than the cross-sectional area of ​​the main body of the water distribution pipe body 1. As a result, the water flow will form a greater water pressure at the upstream position of the water passage gap 4, so that the water outlet 2 at this position can distribute more water.

[0025] Two sets of guide plates 3 are evenly distributed at the water outlet 2 of each group. The bottom of all the guide plates 3 are flush, and the bottom of the guide plates 3 is a circular plate structure. As the guide plates 3 go up, they gradually become a gradually expanding plate structure. That is to say, the curvature of the bottom of the guide plates 3 is larger and the curvature of the top decreases. In other words, the guide plates 3 become more gentle as they go up. This can make the water flow in the water distribution pipe 1 more stable and reduce turbulence and eddies.

[0026] Furthermore, the length of the guide plate 3 near the inlet 5 is greater than the length of the guide plate 3 away from the inlet 5. In other words, the length of the guide plate 3 is negatively correlated with the distance from the guide plate 3 to the inlet 5. Figure 1 or Figure 2 As shown, on the side closer to the inlet 5, the bottom curvature of the guide plate 3 is larger, while the top curvature is smaller, resulting in a gentler inclination and a longer length. Conversely, on the side farther from the inlet 5, both the bottom and top curvatures of the guide plate 3 are larger, leading to a steeper inclination and a shorter length. Because the water flow near the inlet 5 is larger and has not yet been diverted by the distributor 2, or the diversion is minimal, the guide plate 3 is more gently sloping, which can improve the water flow at the distributor 2 to some extent. Conversely, the water flow far from the inlet 5 is smaller, so to ensure the water flow at the distributor 2, the guide plate 3 needs to be designed to be steeper, improving its interception effect. This ensures that the water flow and pressure at the distributor 2 far from the inlet 5 are closer to those at the distributor 2 near the inlet 5, thereby achieving uniform water distribution at each distributor 2 location and improving the water distribution effect of the distributor.

[0027] It should be noted that in this embodiment, the guide plate 3 does not need to be arranged at the water inlet 2 on the side closest to the water inlet 5 of the water distribution pipe body 1, such as... Figure 1 or Figure 2 As shown, at the position closest to the inlet 5, the water flow and water pressure at the branch outlet 2 are at a relatively high level, so there is no need to add a guide plate 3 for guiding the flow; the specific design can be considered according to actual needs.

[0028] In this embodiment, the radial dimension of the water distribution pipe body 1 is larger than the radial dimensions of its inlet 5 and outlet 6. A guide plate 3 structure needs to be arranged inside the water distribution pipe body 1, therefore the internal dimensions of the water distribution pipe body 1 need to be designed to be larger. Simultaneously, this allows for a certain increase in the width of the guide plate 3, improving its flow interception effect. Furthermore, the guide plate 3 is fixed to the inner wall of the water distribution pipe body 1 using a detachable connection method. Specifically, a slot structure can be designed on the inner wall of the water distribution pipe body 1, and the guide plate 3 can be inserted into the slot for fixation. The water distribution pipe body 1 can also adopt a half-structure design.

[0029] Example 2: As Figures 1 to 5 The illustration shows a novel water distributor, comprising a water distribution pipe body 1 with an inlet 5 and an outlet 6 at its two ends. The middle section of the water distribution pipe body 1 is approximately rectangular. Four sets of water distribution outlets 2 are provided on the water distribution pipe body 1, located below the water distribution pipe body 1 (as shown in the illustration). Corresponding to the positions of some of the water distribution outlets 1, guide plates 3 are provided on the inner wall of the water distribution pipe body 1. The guide plates 3 are curved arcs, with their bottoms located on the openings of the water distribution outlets 2. The top of the guide plate 3 is located at the top of the water distribution pipe body 1 (i.e., away from the water outlet 2). The interior of the water distribution pipe body 1 is a rectangular cavity, and the guide plate 3 is arranged on the vertical cavity wall inside the water distribution pipe body 1, inclined along the water flow direction inside the water distribution pipe body 1. The guide plate 3 has an arc-shaped structure, with its convex surface in the same direction as the water flow inside the water distribution pipe body 1. That is, the concave surface of the guide plate 3 faces the water inlet 5 of the water distribution pipe body 1. When the water flows inside the water distribution pipe body 1, the water flows along the concave surface of the guide plate 3. Since the top of the guide plate 3 extends all the way to the top of the water distribution pipe body 1, the water cannot flow away from the top of the guide plate 3, and can only flow downstream along the width of the guide plate 3. Thus, the guide plate 3 can guide the water flow to the location of the water outlet 2, so that there is more water flow and greater water pressure above the water outlet 2.

[0030] The guide plate 3 is made of high-strength stainless steel, possessing excellent pressure resistance and corrosion resistance. The surface of the guide plate 3 also requires polishing to reduce surface friction resistance. Each water outlet 2 can have one or two sets of guide plates 3. When there is one set of guide plates 3, they are arranged on any vertical side wall of the water distribution pipe 1. Water in the water distribution pipe 1 is guided to the location of the water outlet 2 after passing through the guide plates 3. When there are two sets of guide plates 3, they are arranged on two vertical side walls of the water distribution pipe 1 in a symmetrical distribution. When water flows through the guide plates 3, the guide plates 3 on both sides converge the water towards the location of the water outlet 2. In this embodiment, two sets of guide plates 3 are used for illustration.

[0031] Two sets of guide plates 3 are arranged at intervals on the water distribution pipe body 1, and a water passage gap 4 is formed between the two sets of guide plates 3. The water passage gap 4 allows water to flow through the inside of the water distribution pipe body 1. At the same time, due to the presence of the two sets of guide plates 3, the water passage area of ​​the water passage gap 4 is smaller than the cross-sectional area of ​​the main body of the water distribution pipe body 1. As a result, the water flow will form a greater water pressure at the upstream position of the water passage gap 4, so that the water outlet 2 at this position can distribute more water.

[0032] Two sets of guide plates 3 are evenly distributed at the water outlet 2 of each group. The bottom of all the guide plates 3 are flush, and the bottom of the guide plates 3 is a circular plate structure. As the guide plates 3 go up, they gradually become a gradually expanding plate structure. That is to say, the curvature of the bottom of the guide plates 3 is larger and the curvature of the top decreases. In other words, the guide plates 3 become more gentle as they go up. This can make the water flow in the water distribution pipe 1 more stable and reduce turbulence and eddies.

[0033] Furthermore, the length of the guide plate 3 near the inlet 5 is greater than the length of the guide plate 3 away from the inlet 5. In other words, the length of the guide plate 3 is negatively correlated with the distance from the guide plate 3 to the inlet 5. Figure 1 or Figure 2 As shown, on the side closer to the inlet 5, the bottom curvature of the guide plate 3 is larger, while the top curvature is smaller, resulting in a gentler inclination and a longer length. Conversely, on the side farther from the inlet 5, both the bottom and top curvatures of the guide plate 3 are larger, leading to a steeper inclination and a shorter length. Because the water flow near the inlet 5 is larger and has not yet been diverted by the distributor 2, or the diversion is minimal, the guide plate 3 is more gently sloping, which can improve the water flow at the distributor 2 to some extent. Conversely, the water flow far from the inlet 5 is smaller, so to ensure the water flow at the distributor 2, the guide plate 3 needs to be designed to be steeper, improving its interception effect. This ensures that the water flow and pressure at the distributor 2 far from the inlet 5 are closer to those at the distributor 2 near the inlet 5, thereby achieving uniform water distribution at each distributor 2 location and improving the water distribution effect of the distributor.

[0034] It should be noted that in this embodiment, the guide plate 3 does not need to be arranged at the water inlet 2 on the side closest to the water inlet 5 of the water distribution pipe body 1, such as... Figure 1 or Figure 2 As shown, at the position closest to the inlet 5, the water flow and water pressure at the branch outlet 2 are at a relatively high level, so there is no need to add a guide plate 3 for guiding the flow; the specific design can be considered according to actual needs.

[0035] A water distribution connector 7 is installed at the water outlet 2 of the water distribution pipe body 1. One end of the water distribution connector 7 is sealed to the water distribution pipe body 1, and the other end of the water distribution connector 7 is provided with a threaded section for connecting to an external pipeline structure. A valve assembly is also installed on the water distribution pipe body 1. Specifically, the valve assembly includes a valve plate 9, a valve stem 8, and a valve seat 11. The valve seat 11 is arranged on the opposite side of the water distribution pipe body 1 corresponding to the water outlet 2, and is fixedly connected to the water distribution pipe body 1. A valve switch 10 is installed on the valve seat 11. One end of the valve stem 8 is connected to the valve switch 10, and the other end of the valve stem 8 is connected to the valve plate 9. The valve plate 9 is positioned directly above the water outlet 2. By operating the valve switch 10, the valve stem 8 is moved, which in turn moves the valve plate 9 to close or open the water outlet 2, thereby controlling the on / off state of the water outlet 2. Specifically, the valve assembly can be electrically controlled or manually controlled.

[0036] The water passage gap 4 formed by the two guide plates 3 inside the water distribution pipe body 1 is larger than the overall radial dimension of the valve stem 8 and valve plate 9. The radial dimension of the valve plate 9 and valve stem 8 needs to be smaller than the water passage gap 4 to prevent the valve plate 9 from interfering with the guide plate 3 and affecting the installation of the guide plate 3 and the guiding effect of the guide plate 3.

[0037] In this embodiment, the radial dimension of the water distribution pipe body 1 is larger than the radial dimensions of its inlet 5 and outlet 6. A guide plate 3 structure needs to be arranged inside the water distribution pipe body 1, therefore the internal dimensions of the water distribution pipe body 1 need to be designed to be larger. Simultaneously, this allows for a certain increase in the width of the guide plate 3, improving its flow interception effect. Furthermore, the guide plate 3 is fixed to the inner wall of the water distribution pipe body 1 using a detachable connection method. Specifically, a slot structure can be designed on the inner wall of the water distribution pipe body 1, and the guide plate 3 can be inserted into the slot for fixation. The water distribution pipe body 1 can also adopt a half-structure design.
