Description

Technical Field

[0001] The present application relates to the technical field of water distribution equipment, and particularly to a flow-equalizing water distribution structure and a water distribution device. Background Art

[0002] A water distributor refers to a device that distributes water volume regularly over a certain working area, and is usually used in filtration equipment, water treatment equipment, and valve-free filters. Conventional water distributors include a main pipe, branch pipes provided on the main pipe, and water distribution heads provided on the branch pipes. The water distribution heads have a plurality of equally-diameter small holes evenly distributed. Water flows from the main pipe into the branch pipes, and then from the branch pipes into the water distribution heads and is finally distributed on the working surface.

[0003] Conventional water distributors usually input water into the main pipe with a relatively large water pressure. The water flow fills the main pipe under pressure and then flows into the branch pipes. When the water flow flows from the branch pipes to the water distribution heads, the water flow continuously rushes into the branch pipes under the action of pressure. After the water flow is blocked by the end of the branch pipe and rebounds, the water flow in the branch pipes becomes unstable, affecting the water distribution uniformity of the water distribution heads; at the same time, conventional water distributors are formed by manual assembly of PVC plastics, with low production efficiency and structural strength, and are easily detached under the influence of water flow during use, and have a short service life.

[0030] Embodiment 1

[0031] Referring to Figure 1 and Figure 2 On the one hand, this application provides a uniform-flow water distribution structure, including a water distribution pipe 1. One end of the water distribution pipe 1 is provided with a water flow regulating structure 2, and the other end of the water distribution pipe 1 is provided with a uniform-flow structure 3 and a water distribution plate 4. When using the water distribution pipe 1, water flow enters the water distribution pipe 1 from the water flow regulating structure 2. The water flow regulating structure 2 controls the water flow. The water flow flows in the water distribution pipe 1 to the uniform-flow structure 3 and the water distribution plate 4. The uniform-flow structure 3 equalizes the water flow, and finally the water flow enters the water distribution plate 4 for water distribution, thereby ensuring the uniformity of water distribution.

[0032] Specifically, the water distribution pipe 1 is horizontally arranged. The water flow regulating structure 2 includes a flow-limiting pressure reducer 21. The flow-limiting pressure reducer 21 is arranged at one end of the water distribution pipe 1. One end of the flow-limiting pressure reducer 21 is the input end, and the other end of the flow-limiting pressure reducer 21 extends along the length direction of the water distribution pipe 1 and faces the uniform-flow structure 3. When water flow is input, the water flow enters the flow-limiting pressure reducer 21 from the input end. The flow-limiting pressure reducer 21 controls the passing amount and passing speed of the water flow. After passing through the flow-limiting pressure reducer 21, the water flow enters the water distribution pipe 1 and is transported along the water distribution pipe 1 to the uniform-flow structure 3.

[0033] The uniform-flow structure 3 includes a water distribution connecting member 31. The water distribution connecting member 31 is provided with a water blocking component 32 and a water dividing component 33. The water distribution connecting member 31 is connected to the water distribution plate 4 through the water blocking component 32 and the water dividing component 33 in sequence. The water distribution plate 4 is provided with a number of water distribution holes 41, and the number of water distribution holes 41 communicates with the water dividing component 33.

[0034] The water distribution connecting member 31 is a water distribution tee, and the water distribution tee is in a "T" shape. The water distribution connecting member 31 includes a connecting portion 311 located above and a connecting portion 312 located below, and the connecting portion 311 and the connecting portion 312 are fixedly connected. The connecting portion 311 is arranged on the water distribution pipe 1. In this embodiment, the connecting portion 311 is a part of the water distribution pipe 1. One end of the connecting portion 312 is connected to the lower part of the connecting portion 311, and the other end of the connecting portion 312 is connected to the water distribution plate 4. It can be understood that the connecting portion 311 or the connecting portion 312 can also be a component independent of the water distribution pipe 1. To ensure the assembly efficiency and the overall structural strength, the water distribution connecting member 31 and the water distribution pipe 1 are integrally formed, and the water distribution pipe 1, the flow-limiting pressure reducer 21, the uniform structure and the water distribution plate 4 are all made of stainless steel.

[0035] Meanwhile, in order to further improve the water distribution uniformity, a flow buffer (not shown in the figure) is arranged on the connecting portion 311. The flow buffer is used to further slow down the water flow speed. When the water flow flows into the flow buffer, the flow buffer will control the water flow speed according to the preset parameters, so that the water flow evenly flows into the connecting portion 311.

[0036] The water blocking assembly 32 includes a plurality of baffles, and the plurality of baffles are arranged at the connection between the connecting portion 311 and the connecting portion 312. In this embodiment, the water blocking assembly 32 includes two baffles, which are an axial baffle 321 and a radial baffle 322 respectively. The axial baffle 321 is parallel to the axial direction of the water distribution pipe 1, and the radial baffle 322 is parallel to the radial direction of the water distribution pipe 1. The axial baffle 321 and the radial baffle 322 are perpendicularly connected. At the same time, the radial baffle 322 is provided with water passing grooves 3221, and the water passing grooves 3221 are located on both sides of the radial baffle 322. By arranging the axial baffle 321 and the radial baffle 322, after the flow buffer controls the water flow, the water flow will be blocked by the axial baffle 321 and the radial baffle 322 and then enter the water distribution component 33. By arranging the water passing grooves 3221, a part of the water flow can be effectively blocked and stay in the current area, while the other part of the water flow continues to flow to the subsequent area.

[0037] The water distribution component 33 includes a plurality of water distribution plates. There is an angle between the plurality of water distribution plates and they are arranged on the connecting portion 312. The plurality of water distribution plates are connected to the baffle, and the plurality of water distribution plates are evenly distributed along the circumferential direction of the connecting portion 312. The plurality of water distribution plates are separated to form a plurality of water distribution cavities, and the water distribution cavities face the water distribution holes 41 and correspond one by one. In this embodiment, four water distribution holes 41 are opened on the water distribution plate 4, so there are four corresponding water distribution plates. The included angle between the four water distribution plates is ninety degrees and they all face the water distribution holes 41. After being separated by the water distribution component 33, the water flow evenly flows into the water distribution plate 4.

[0038] The water distribution plate 4 includes a plate body, in which a water inlet hole 42 is formed. The plate body is connected to a water distribution tee through the water inlet hole 42, and the water distribution component 33 is inserted into the water inlet hole 42. A water storage cavity is formed in the plate body, and the water storage cavity is communicated with the water inlet hole 42. After being separated and guided by the water distribution component 33, the water flow evenly flows to the water distribution plate 4 and flows out from the water distribution holes 41, so as to achieve a uniform water distribution effect.

[0040] Referring to Figure 3 , on the other hand, the present application provides a water distribution device, which includes a main water pipe 5 and a plurality of water distribution structures arranged on the main water pipe 5. The water distribution structure is a flow equalizing water distribution structure as described above. In order to achieve a better water distribution effect, a plurality of water distribution structures are evenly arranged on both sides of the main water pipe 5, and a plurality of water distribution structures are arranged on the main water pipe 5 and arranged at intervals.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
