Description

Technical Field

[0001] The utility model relates to the technical field of pipeline equipment, and more specifically to a noise-reducing building drainage pipeline. Background Art

[0002] Existing water pipe systems usually cause noise in buildings at night due to factors such as excessively fast water flow, collision between water flow and pipe wall, and vortexes formed by water flow in the pipe, which is not convenient for use in some environments that strictly require quietness. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a noise-reducing building drainage pipe to solve the problem that the existing water pipe system in the above-mentioned background technology usually causes noise in the building at night due to factors such as excessively fast water flow speed, collision of water flow with the pipe wall, and vortex formed by water flow in the pipe, which is inconvenient to use in some environments that strictly require quietness.

[0004] The utility model provides the following technical scheme: comprising a water inlet pipe, a flow control valve is installed on the top end of the water inlet pipe through a threaded fixed seal, a flow detector is integrated on the flow control valve, the flow control valve and the flow detector are electrically connected, an acceleration pipe is installed on the bottom end of the water inlet pipe through a threaded fixed seal, the diameter of the acceleration pipe is smaller than the diameter of the water inlet pipe, a deceleration pipe is installed on the bottom end of the acceleration pipe through a threaded fixed seal, the diameter of the deceleration pipe gradually increases, and the shape of the deceleration pipe is a truncated cone, and an outlet pipe is fixedly welded and installed on the bottom end of the deceleration pipe. When in use, it can be concluded that the noise of water flow is caused by the collision caused by excessive water flow velocity. Therefore, a flow control valve with an integrated flow detector can be installed at the top of the water inlet pipe to control the water flow entering the water inlet pipe. The flow detector will detect the flow. If the flow velocity is too fast, the flow control valve will be controlled to reduce the flow velocity. At the same time, the diameters of the three main pipes, the water inlet pipe, the acceleration pipe, and the deceleration pipe are all different. This utilizes the relationship formula between the pipe diameter and the flow velocity in fluid mechanics. Therefore, the water flow velocity can be controlled by controlling the pipe diameter. The water inlet pipe is thicker and stabilizes the flow velocity. The diameter of the acceleration pipe is the thinnest and is used to accelerate the water flow. The diameter of the deceleration pipe is getting thicker and thicker and is used to reduce the water flow velocity. In this way, the water pressure can be controlled by controlling the flow velocity, thereby reducing noise, effectively solving the problem that the existing water pipe system usually causes noise at night in buildings due to factors such as excessive water flow velocity, collision of water flow with the pipe wall, and vortex formed by water flow in the pipe, which is not convenient for use in some environments that strictly require quietness.

[0005] Furthermore, a water flow damping pipe is fixedly installed on the inner wall of the water inlet pipe and the acceleration pipe, and the main material of the water flow damping pipe is fluororubber. A noise silencing layer is fixedly installed on the inner wall of the water flow damping pipe, and the main material of the noise silencing layer is closed-cell polyethylene. When in use, the water flow damping pipe can be used as a buffer layer to effectively reduce the noise caused by the contact between the water flow and the pipe, and the noise silencing layer can further eliminate these noises, making the final sound smaller.

[0006] Furthermore, a plurality of vortex suppression plates are fixedly mounted on the inner wall of the accelerating pipe, and the main body material of the vortex suppression plates is a hard PVC plastic plate. When in use, these vortex suppression plates can divide the water flow and reduce the vortex generated by a single water flow, thereby reducing noise.

[0007] Furthermore, the inlet and outlet of the acceleration pipe are fixed with a sound-absorbing expansion ball through a metal bracket, and the main material of the sound-absorbing expansion ball is fluororubber. In order to reduce the noise and mechanical stress in the drainage pipe system, multiple sound-absorbing expansion balls can be installed to reduce the noise caused by water flow impact.

[0008] Furthermore, damping shock absorbers are fixedly installed on both sides of the water inlet pipe, the acceleration pipe, and the deceleration pipe, and mounting plates are fixedly installed on the sides of the damping shock absorbers away from each other. When in use, the damping shock absorbers can effectively reduce the vibration of the pipeline equipment caused by the water flow, thereby further reducing the noise of the pipeline from the external bracket.

[0009] Furthermore, the main body materials of the water inlet pipe, the acceleration pipe, the deceleration pipe, and the outlet pipe are all stainless steel.

[0012] 2. The utility model is provided with a water flow shock absorbing tube and a noise silencing layer.

[0021] A water flow shock absorbing tube 115 is fixedly installed on the inner wall of the water inlet pipe 100 and the accelerating pipe 112. The main material of the water flow shock absorbing tube 115 is fluororubber. A noise silencing layer 116 is fixedly installed on the inner wall of the water flow shock absorbing tube 115. The main material of the noise silencing layer 116 is closed-cell polyethylene.

[0022] A plurality of eddy current suppression plates 117 are fixedly mounted on the inner wall of the accelerating pipe 112 , and the main body material of the eddy current suppression plates 117 is a hard PVC plastic plate.

[0023] Working principle: When in use, it can be concluded that the noise of water flow is caused by the collision caused by excessive water flow velocity. Therefore, the flow rate of water entering the water inlet pipe 100 can be controlled by installing a flow control valve 110 with an integrated flow detector 111 at the top of the water inlet pipe 100. The flow detector 111 will detect the flow rate. If the flow rate is too fast, the flow control valve 110 will be controlled to reduce the flow rate. At the same time, the diameters of the three main pipes of the water inlet pipe 100, the acceleration pipe 112, and the deceleration pipe 113 are all different. This utilizes the relationship formula between the pipe diameter and the flow rate in fluid mechanics. Therefore, the water flow rate can be controlled by controlling the pipe diameter. The water inlet pipe 100 is relatively thick and stabilizes the flow rate. The diameter of the acceleration pipe 112 is the thinnest and is used to accelerate the water flow. The diameter of the deceleration pipe 113 is getting thicker and thicker, which is used to reduce the water flow rate. In this way, the water pressure can be controlled by controlling the flow rate, thereby reducing noise.

[0027] The main body materials of the water inlet pipe 100, the acceleration pipe 112, the deceleration pipe 113, and the outlet pipe 114 are all stainless steel.

[0028] Working principle: When in use, the damping shock absorber 119 can effectively reduce the vibration of the pipeline equipment caused by water flow, thereby further reducing the noise of the pipeline from the external bracket.
