[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes a water supply and drainage noise reduction component, comprising:

[0039] Main pipeline 1;

[0040] The reducer 2 is arranged in the main pipe 1 and has a guide cavity 2-1. The cross-sectional area of ​​the guide cavity 2-1 decreases from top to bottom. The guide cavity 2-1 is used to guide the water flow in the main pipe 1.

[0041] The flow dividing piece 3 is threadedly arranged on the main pipe 1. The flow dividing piece 3 has a flow dividing end 3-1. The flow dividing end 3-1 is located in the main pipe 1 and below the guide cavity 2-1, and is used for dividing the water flow in the guide cavity 2-1.

[0042] In the present embodiment, in order to solve the problem in the related art that the noise reduction of the pipeline is to wrap the sound insulation cotton, and the sound insulation cotton wrapping process is cumbersome, the present scheme designs a reducer 2. Since the diameter of the guide cavity 2-1 of the reducer 2 is larger at the water inlet and smaller at the water outlet, when the water flow in the main pipe 1 is small, it flows out directly through the water outlet of the reducer 2. The water outlet can center the water flow, reducing the frequency of noise generated by the friction between the water flow and the inner wall of the main pipe 1. When the water flow is large, the water flow flows out from the water outlet of the reducer 2 and passes through the diverter 3. The diverter 3 disperses the vertically falling water flow and guides the diversion at the diversion end 3-1, thereby reducing the impact force of the water flow and the inner wall of the pipe, thereby reducing the noise.

[0043] Further, the diverter 3 comprises:

[0044] A mounting seat 4, threadedly arranged on the main pipe 1;

[0045] The rubber pad 5 is arranged on the mounting seat 4 and is located in the main pipeline 1 . The rubber pad 5 is used for noise reduction. The diversion end 3 - 1 is arranged on the rubber pad 5 .

[0046] In this embodiment, in order to enhance the effect of reducing noise, a threaded hole is designed on the main pipe 1, the mounting seat 4 is threadedly arranged in the threaded hole, the rubber pad 5 is fixed on the mounting seat 4, and the mounting seat 4 is sealed inside the main pipe 1. The rubber pad 5 is arranged with a diversion end 3-1. After the diversion end 3-1 diverts the water flow, the water flow falls on the rubber pad 5. The rubber pad 5 has a good sound absorption effect. Through the action of the rubber pad 5, the water flow is directly prevented from colliding with the inner wall of the pipe at the bend, greatly reducing the noise. At the same time, the mounting seat 4 and the main pipe 1 are threadedly matched, so that the rubber pad 5 can be replaced.

[0047] Further, the mounting seat 4 has a mounting hole 4-1, the rubber pad 5 has a mounting protrusion 5-4, the mounting protrusion 5-4 is arranged in the mounting hole 4-1, the rubber pad 5 and the mounting seat 4 have a slide groove 5-2, the slide groove 5-2 has a limiting groove 5-3, and the diverter 3 also includes:

[0048] The flow divider 3 - 2 is slidably disposed in the slide groove 5 - 2 and has a limiting protrusion 5 - 1 . The limiting protrusion 5 - 1 is slidably disposed in the limiting groove 5 - 3 . The flow divider end 3 - 1 is located on the flow divider 3 .

[0049] In this embodiment, in order to adjust the height of the diverter end 3-1 and enhance the fit between the diverter end 3-1 and the outlet of the reducer 2, a slide groove 5-2 is designed on the rubber pad 5 and the mounting seat 4. Through the limiting protrusion 5-1, the diverter 3 can only be lifted and slid along the slide groove 5-2. After the diverter 3 is lifted and slid, the diverter end 3-1 slides into or out of the guide cavity 2-1. When the water flow is greater, the noise reduction effect is better when the diverter end 3-1 is located in the guide cavity 2-1.

[0050] Furthermore, it also includes:

[0051] The threaded rod 3-3 is rotatably arranged on the mounting seat 4, and the flow divider 3-2 is threadably arranged on the threaded rod 3-3. After the threaded rod 3-3 rotates, it drives the flow divider 3-2 to slide along the slide groove 5-2.

[0052] In this embodiment, in order to realize the sliding of the diverter 3, a threaded rod 3-3 is designed in this scheme. By rotating the threaded rod 3-3, the diverter 3 can be lifted and slid. Due to the limitation of the mounting protrusion 5-4 and the limiting protrusion 5-1, the diverter 3 can only be lifted and slid, but cannot be rotated. Since the threaded rod 3-3 rotates on the mounting seat 4, the threaded rod 3-3 will not be lifted or lowered, and the threaded rod 3-3 can always be used as a mechanical switch to control the lifting.

[0053] Furthermore, the cross-sectional area of ​​the flow divider 3-2 gradually increases from top to bottom.

[0054] In this embodiment, in order to achieve the effect of diversion and noise reduction, the diverter 3 is designed as a structure in which the cross-sectional area increases from top to bottom. After the water flows through the diversion at the top of the diverter 3, it flows down along the guide slope of the diverter 3, and the guide slope reduces the impact force of the water flow.

[0055] Further, the mounting seat 4 and the rubber pad 5 form a sealed cavity 4-2, which also includes:

[0056] The observation protrusion 6 is made of a transparent material, is disposed below the mounting seat 4, and has an observation cavity 6-1, which is connected to the sealing cavity 4-2.

[0057] In this embodiment, in order to prevent water leakage at the installation point of the rubber pad 5 and the mounting seat 4, an observation protrusion 6 is designed on the mounting seat 4. The observation protrusion 6 is designed to be a transparent material. The observation protrusion 6 is located below the mounting seat 4. Therefore, only when water leakage occurs, water will accumulate in the observation protrusion 6. The water leakage can be easily observed manually, and the mounting seat 4 can be unscrewed and replaced in time.

[0058] Furthermore, the diameter reducing member 2 is made of a deformable rubber material.

[0059] In this embodiment, in order to prevent the reducer 2 from limiting the flow, the reducer 2 is designed to be a deformable rubber material. The rubber material can reduce noise. When the water flow in the main pipe 1 increases, the cross-sectional area at the outlet of the reducer 2 increases, and can be increased to the same size as the inner diameter of the main pipe 1 to facilitate the outflow of water. When the water flow in the main pipe 1 is large enough, that is, the cross-sectional area at the outlet of the reducer 2 is the same size as the inner diameter of the main pipe 1, there is a high probability that no noise will be generated in the main pipe 1.

[0060] Further, the main pipeline 1 comprises:

[0061] A vertical pipe 1-1, a reducer 2 is arranged on the vertical pipe 1-1;

[0062] A connecting elbow 1-2, one end of which is arranged on the vertical pipe 1-1, and a mounting seat 4 is threadedly arranged on the connecting elbow 1-2;

[0063] The transverse pipe 1-3 is arranged on the other end of the connecting elbow 1-2.

[0064] In this embodiment, the main pipeline 1 in this solution has a vertical pipeline 1-1 and a connecting elbow 1-2. The reducer 2 is located in the vertical pipeline 1-1 to reduce the noise generated by the vertical pipeline 1-1. The noise in the connecting elbow 1-2 is formed by the impact of water flow on the bend, so the mounting seat 4 is designed at the connecting elbow 1-2 in this solution. The rubber pad 5 and the diverter 3 work together to reduce the noise at the connecting elbow 1-2.

[0065] Furthermore, it also includes:

[0066] The guide block 4-3 is arranged in the connecting elbow 1-2 and abuts against the mounting seat 4. The guide block 4-3 has a guide surface 4-4, and the guide surface 4-4 leads to the transverse pipe 1-3.

[0067] In this embodiment, in order to facilitate the separated water flow to flow into the transverse pipe 1-3, a guide surface 4-4 is designed at the connection between the mounting seat 4 and the transverse pipe 1-3. The water flow is guided by the guide surface 4-4 and flows smoothly into the transverse pipe 1-3, preventing the water flow from being directly cut off and flowing into the transverse pipe 1-3 to generate noise.

[0068] Furthermore, it also includes:

[0069] The handle 7 is arranged on the threaded rod 3 - 3 and is used to control the rotation of the threaded rod 3 - 3 .

[0070] In this embodiment, in order to facilitate the twisting of the threaded rod 3-3, a handle 7 is designed at the end of the threaded rod 3-3 exposed from the mounting seat 4. The handle 7 is controlled manually to drive the threaded rod 3-3 to rotate.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
