Abstract

The invention relates to a sound-absorbing water flow diverter. The inner wall of the first section is provided with a first spiral part; the inner wall of the second section is provided with a second spiral part opposite to the spiral direction of the first spiral part; wherein, the first spiral part is provided with a first spiral part. One segment moves into the liquid within the second segment to counteract the acoustic energy within the liquid. When the liquid enters the second section from the first section, the movement of the liquid will be along the direction of the first spiral section. Since the spiral direction of the second spiral part is opposite to that of the first spiral part, the movement of the liquid in the second section will produce vortices and turbulent structures that cancel each other out. Through the interaction of vortices and turbulence, the sound wave energy inside the liquid is effectively offset and attenuated, thereby reducing the generation of noise. The energy of liquid flow is converted into vortex motion and its energy is dissipated through interaction, thereby reducing the propagation of sound waves.

Description

Sound-absorbing water flow diverter

Technical field

The present invention relates to the technical field of water flow diverters, and in particular to a sound-absorbing water flow diverter.

Background technique

Flow diverter, in liquid or gas fluid mechanics, a diverter is often used to divert fluids into different pipes for the purpose of dividing, mixing, distributing or controlling fluid flow.

During use, water will flow in the pipe, and the liquid in the pipe will be diverted through the diverter to transport the water to the required branch pipes. However, when water flows in the pipe of the diverter, when the water velocity is too high, the water flow will produce turbulence in the pipe.

Turbulence itself produces noise, and when water velocity increases, turbulence becomes more intense, causing water molecules to collide with each other and increase friction, thereby increasing noise levels. High-speed turbulent flow has higher frequency components, resulting in high-frequency noise. These high-frequency noises may cause discomfort to human ears and may affect the comfort of the surrounding environment. Pressure fluctuations in high-speed turbulent flows can cause an increase in sound pressure levels. As the flow velocity increases, the sound pressure level of turbulence noise also increases accordingly.

Please refer to Figures 1 to 4. One embodiment of the present invention provides a sound-absorbing water flow diverter. The sound-absorbing water flow diverter 100 in this embodiment includes:

Connecting pipe 110, the connecting pipe 110 has a first section 111 and a second section 112 connected with the first section 111;

A first spiral portion 1111 is provided on the inner wall of the first section 111;

The inner wall of the second section 112 is provided with a second spiral part 1121 opposite to the spiral direction of the first spiral part 1111;

The liquid entering the second section 112 from the first section 111 moves to offset the acoustic wave energy in the liquid.

In this embodiment, the sound-absorbing water flow diverter 100 includes a connecting pipe 110, which is divided into a first section 111 and a second section 112. These two segments are interconnected and form a channel for liquid flow.

When the liquid enters the second section 112 from the first section 111, the movement of the liquid will be along the direction of the first spiral portion 1111. Since the spiral direction of the second spiral part 1121 is opposite to that of the first spiral part 1111, the movement of the liquid in the second section 112 will generate vortices and turbulent structures that cancel each other.

Through the interaction of vortices and turbulence, the sound wave energy inside the liquid is effectively offset and attenuated, thereby reducing the generation of noise. The energy of liquid flow is converted into vortex motion and its energy is dissipated through interaction, thereby reducing the propagation of sound waves.

The sound-absorbing water flow diverter 100 achieves the effect of reducing noise by arranging intersecting spiral parts to consume the sound wave energy generated during liquid flow.

In at least one embodiment of the present application, the length of the first spiral portion 1111 is equal to the length of the second spiral portion 1121 .

In at least one embodiment of the present application, the first section 111 is provided with a first inlet 111a and a first outlet 111b connected to the first inlet 111a; the first spiral portion 1111 is formed from the first inlet 111a. 111a extends to the first outlet 111b.

In at least one embodiment of the present application, the second section 112 is provided with a second inlet 112a and a second outlet 112b connected with the second inlet 112a; the second spiral portion 1121 is formed from the second inlet 112a. 112a extends to the second outlet 112b.

In this embodiment, the lengths of the first spiral part 1111 and the second spiral part 1121 in the sound-absorbing water flow diverter 100 are equal. The flow distance of the liquid inside the diverter is consistent, ensuring that the flow rate and flow conditions of the liquid throughout the diverter are basically the same.

The first section 111 has an inlet and an outlet connected to the inlet, and the first spiral portion 1111 extends from the inlet to the outlet. Let the liquid enter the first section 111 from the inlet, then flow along the spiral path of the first spiral portion 1111, and finally flow out from the outlet.

The second section 112 has an inlet and an outlet connected to the inlet, and the second spiral portion 1121 extends from the inlet to the outlet. The liquid passing through the first section 111 enters the second section 112, then flows along the spiral path of the second spiral portion 1121, and finally flows out from the second outlet 112b.

When the liquid enters the first section 111 from the first inlet 111a, it will be guided to flow along the spiral path of the first spiral portion 1111. This spiral motion of liquid flow can increase the friction between the liquid and the inner wall of the diverter, thereby improving the dissipation effect of sound wave energy.

Next, the liquid passing through the first section 111 flows into the second section 112 and further flows along the spiral path of the second spiral portion 1121 . The spiral direction of the second spiral part 1121 is opposite to that of the first spiral part 1111. This intersecting spiral motion can further increase the generation of turbulence and promote the dissipation of sound wave energy inside the liquid.

The liquid has experienced multiple turbulent flows inside the diverter, so that the sound wave energy inside the liquid is effectively offset and attenuated. This spiral path design can increase the contact area between the liquid and the inner wall of the diverter, improve the dissipation efficiency of sound wave energy, and thereby reduce the generation of noise.

By guiding the liquid inside the diverter to flow along intersecting spiral paths, namely the first spiral portion 1111 and the second spiral portion 1121 , more effective sound wave energy dissipation and sound absorption effects can be achieved.

There are at least two first spiral parts 1111 , and the two first spiral parts 1111 are arranged at equal angles in the inner wall of the first section 111 ; there are at least two second spiral parts 1121 . The two second spiral parts 1121 are arranged in the inner wall of the second section 112 at equal angles.

The first spiral portion 1111 is a spiral semicircular protrusion protruding from the inner tube of the first section 111 , and the second spiral portion 1112 is a spiral semicircular protrusion protruding from the inner tube of the second section 112 .

In at least one embodiment of the present application, the connecting pipe 110 also has a third section 113, which is located between the first section 111 and the second section 112. The third end Connected to the first section 111 and the second section 112, the diameter of the third section 113 is marked as a, the diameter of the second section 112 is marked as b, and the diameter of the first section 111 is marked as c;

Satisfy the relationship:

a>b, a>c.

Please refer to Figures 1-4. In this embodiment, the third section 113 is located between the first section 111 and the second section 112 and is connected with them. The liquid enters the third section 113 from the first section 111, then enters the second section 112, and finally flows out from the second section 112. The liquid can pass through several consecutive flow stages inside the diverter.

The diameter of the third section 113 is marked as a, the diameter of the second section 112 is marked as b, and the diameter of the first section 111 is marked as c, and satisfies the relationships a>b, a>c. The diameter of the third section 113 is larger than the diameters of the second section 112 and the first section 111 . By increasing the diameter of the third section 113, a larger flow channel space can be provided, reducing the resistance to liquid flow and reducing the flow rate of the liquid inside the diverter.

Due to the larger diameter of the third section 113, the liquid can gradually decelerate in the third section 113 before entering the second section 112, thereby reducing the impact and turbulence of the liquid. This gradual deceleration helps reduce noise generation and provides a more stable flow environment.

The third section 113 plays a buffering and transitional role during the liquid flow. By increasing the diameter of the third section 113 and placing it between the first section 111 and the second section 112, the speed and turbulence of the liquid flow can be reduced, the generation of noise can be reduced, and a smoother flow effect can be provided. This improves the performance of the acoustic water flow diverter 100, making it more effective in reducing the propagation of acoustic energy and noise.

In at least one embodiment of the present application, the sound-absorbing water flow diverter 100 further includes:

The buffer plate 120 is provided with a plurality of communication holes 120a, and the buffer plate 120 is located at one end close to the first section 111;

The liquid flowing out from the first tube flows into the third section 113 through the communication hole 120a.

In at least one embodiment of the present application, the communication hole 120a has a first opening 120b and a second opening 120c, and the first opening 120b and the second opening 120c are located at both ends of the communication hole 120a, so The first opening 120b is located near one end of the first section 111.

In at least one embodiment of the present application, the aperture of the first opening 120b is marked as d;

The aperture of the second opening 120c is marked as e; it satisfies the relationship: d>e.

In this embodiment, the buffer plate 120 is located at one end close to the first section 111 and has a plurality of communication holes 120a. The function of the buffer plate 120 is to provide a transition area for the liquid flow, slow down the flow speed and reduce the impact force of the flow.

The communication holes 120a are holes located on the buffer plate 120, and they serve to guide liquid from the first section 111 to the third section 113. The communication hole 120a has two openings, namely a first opening 120b and a second opening 120c, which are located at both ends of the communication hole 120a. The first opening 120b is located near one end of the first section 111.

The aperture of the first opening 120b is denoted by d, the aperture of the second opening 120c is denoted by e, and satisfies the relationship d>e. This means that the aperture of the first opening 120b is larger than the aperture of the second opening 120c. A larger hole diameter can provide a larger channel area and reduce resistance and pressure loss when liquid passes through the communication hole 120a.

When the liquid flows out of the first section 111, it enters the third section 113 through the communication hole 120a. The existence of the communication hole 120a allows the liquid flow to smoothly transition from the first section 111 to the third section 113, avoiding sharp pressure changes and rapid changes in flow rate. This helps reduce turbulence and noise generation in liquid flow and provides a more stable flow environment.

The design of the buffer plate 120 and the communication hole 120a plays the role of buffering and smooth transition during the flow of liquid. Through the buffer plate 120 and the communication hole 120a, the liquid can gradually decelerate from the first section 111 and smoothly flow into the third section 113, reducing pressure changes and sudden changes in flow rate, thereby reducing the generation of noise and vibration. At the same time, by controlling the pore size relationship between the first opening 120b and the second opening 120c, the flow rate and flow rate of the liquid can be adjusted, further optimizing the performance of the sound-absorbing water flow diverter 100.

In at least one embodiment of the present application, the connecting pipe 110 further includes:

The diverter part 114 is provided at an end of the second section 112 away from the first section 111;

The diverting part 114 is provided with at least two diverting openings 114a, and the axes of the diverting openings 114a and the second outlet 112b do not coincide with each other.

In at least one embodiment of the present application, the sound-absorbing water flow diverter 100 further includes:

The diverter plate 130 is provided with a plurality of diverter holes 130a;

The axis of the branch port 114a to the axis of the second outlet 112b is marked as g; the relationship is satisfied: 2g>f>g.

Please refer to FIGS. 1-4 . In this embodiment, the diverter part 114 is located at an end of the second section 112 away from the first section 111 . Its function is to divert the fluid from the second section 112 to different outlets to achieve fluid diversion and control. The diverting part 114 is provided with at least two diverting openings 114a, and these diverting openings 114a are located near the axis of the second outlet 112b.

The diverter plate 130 is a plate-shaped structure having a plurality of diverter holes 130a. Its function is to further guide and control the flow of fluid. The diverting holes 130a are located on the diverting plate 130, and through these holes, the fluid can be diverted into different channels.

The axis from the axis of the branching opening 114a to the second outlet 112b is denoted as g, and the axis from the axis of the branching orifice 130a to the axis of the second outlet 112b is denoted as f. According to the relationship 2g>f>g, we can infer the size relationship between f and g.

When the fluid passes through the diverter part 114, the design of the diverter part 114 diverts the fluid into different diverter openings 114a and diverter holes 130a. By adjusting the position and size of the splitting opening 114a and the splitting orifice 130a, the splitting ratio and flow velocity distribution of the fluid can be controlled. This enables more precise fluid diversion and control to meet specific needs.

In this embodiment, the sound-absorbing water flow diverter 100 includes a connecting pipe 110, which is divided into a first section 111 and a second section 112. These two segments are interconnected and form a channel for liquid flow.

When the liquid enters the second section 112 from the first section 111, the movement of the liquid will be along the direction of the first spiral portion 1111. Since the spiral direction of the second spiral part 1121 is opposite to that of the first spiral part 1111, the movement of the liquid in the second section 112 will generate vortices and turbulent structures that cancel each other.

Through the interaction of vortices and turbulence, the sound wave energy inside the liquid is effectively offset and attenuated, thereby reducing the generation of noise.
