Description

Technical Field

[0001] This utility model relates to the field of building drainage equipment technology, specifically a high-flow-rate silent drainage system. Background Technology

[0002] As modern architecture demands increasingly higher living quality, the standards for good housing are also becoming more comprehensive. GB55038-2025, the standard for residential projects, clearly stipulates that drainage is an indispensable part of good housing, with quiet, non-clogging, and odor-free drainage being basic requirements. However, existing drainage technologies have many problems, mainly including low drainage flow, resulting in low drainage efficiency and inability to meet the drainage needs of modern residences; high noise levels, seriously affecting residents' living environment; and design deficiencies, leading to shortcomings in structural rationality and functionality, making drainage systems prone to clogging and odor problems, thus reducing the reliability and practicality of the drainage system. Therefore, there is an urgent need for a high-flow, quiet drainage system that can solve the problems of existing technologies. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a high-flow-rate, quiet drainage system that increases drainage flow and reduces drainage noise.

[0004] The above-mentioned objective of this utility model is achieved through the following technical means:

[0005] A high-flow-rate silent drainage system includes a riser 1, a horizontal branch pipe 2, and a vent 3 located between the riser 1 and the horizontal branch pipe 2. The riser 1 has an inlet end 4 and an outlet end 5. The inlet end 4 is axially offset, has guide vanes 6 inclined towards the pipe wall inside, and has sound-absorbing ribs 7 on the outer wall at the bottom bend.

[0006] Preferably, the horizontal branch pipe 2 includes a first set of horizontal branch pipes 21 located above and close to the water inlet end 4 of the riser pipe 1, and a second set of horizontal branch pipes 22 located below.

[0007] Preferably, the diameter of the first group of horizontal branch pipes 21 is larger than the diameter of the second group of horizontal branch pipes 22.

[0008] Preferably, the vent 3 between the first group of horizontal branch pipes 21 and the vertical pipe 1 is the first vent 31, and the vent 3 between the second group of horizontal branch pipes 22 and the vertical pipe 1 is the second vent 32.

[0009] Furthermore, when the drainage suffix is ​​in the vertical position, the first vent 31 is horizontal between the first set of horizontal branch pipes 21 and the vertical pipe 1.

[0010] Furthermore, the first vent 31 is larger than the second vent 32.

[0011] Preferably, the outer wall of the riser 1 is provided with a water flow indicator 8.

[0012] Preferably, the two ends of the riser 1 are a straight pipe 11 at the water inlet and a straight pipe 12 at the water outlet.

[0013] Preferably, the portion of the riser 1 between the inlet end 4 and the outlet end 5 is an arc-shaped pipe 13.

[0014] Furthermore, the water outlet 5 has a recessed position 14 on the side opposite to the curved pipe 13 for narrowing the pipe wall of the water outlet 5.

[0015] The beneficial effects of adopting the above technical solution are as follows:

[0016] The axial offset design at the inlet end, the guiding effect of the guide vanes, and the noise reduction effect of the sound-absorbing ribs effectively improve the drainage flow and reduce the drainage noise.

[0017] The grouping design of horizontal branch pipes and the setting of different pipe diameters and vent holes optimize the structure of the drainage system, improve drainage efficiency, and reduce the possibility of blockage and backflow of odors.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1. Figures 1-4 A high-flow-rate silent drainage system is shown, including a riser 1, a horizontal branch pipe 2, and a vent 3 located between the riser 1 and the horizontal branch pipe 2. The riser 1 has an inlet end 4 and an outlet end 5. The inlet end 4 is axially offset and has guide vanes 6 inclined towards the pipe wall inside. The outer wall of the bottom bend is provided with sound-absorbing ribs 7.

[0026] Working principle: When water flows into riser 1 from inlet 4, inlet 4 is axially offset, so that the direction of water flow into riser 1 forms a certain angle with the axis of riser 1, reducing the direct impact of water flow on the inner wall of riser 1 and reducing energy loss; the internal guide vanes 6 are inclined towards the pipe wall, which can guide the water flow to swirl down along the wall of riser 1, forming a more stable water flow pattern, reducing turbulence and vortices in riser 1, thereby reducing water flow resistance and increasing drainage flow rate; the sound-absorbing ribs 7 on the outer wall at the bottom bend can absorb the noise generated by the water flow at the bend, thereby reducing the noise during the drainage process through their own structural deformation.

[0027] This embodiment effectively increases drainage flow rate, reduces drainage noise, and makes drainage smoother and quieter, solving the problems of low drainage flow rate and high noise in the prior art.

[0028] Example 2. This example illustrates the installation of a horizontal branch pipe, such as... Figures 1-4 As shown, the horizontal branch pipe 2 includes a first set of horizontal branch pipes 21 located above and close to the water inlet end 4 of the riser pipe 1, and a second set of horizontal branch pipes 22 located below.

[0029] The first set of horizontal branch pipes 21 is used for upper drainage, such as connecting to the toilet drain pipe;

[0030] The second set of horizontal branch pipes 22 is used for lower-level drainage, such as connecting to the sink drain pipe;

[0031] The installation of two sets of horizontal branch pipes enables the rational stratification and drainage of water flow.

[0032] Example 3. Figures 1-4As shown, the diameter of the first set of horizontal branch pipes 21 is larger than that of the second set of horizontal branch pipes 22. The larger diameter allows for a larger flow rate of water; the relatively smaller diameter of the second set of horizontal branch pipes 22 saves materials and optimizes the structure while still allowing for the introduction of water from below. The rational allocation of the horizontal branch pipe diameters improves the overall flow capacity of the drainage system.

[0033] Example 4, as Figure 1 , 3 As shown in Figure 4, the vent 3 between the first group of horizontal branch pipes 21 and the riser 1 is the first vent 31, and the vent 3 between the second group of horizontal branch pipes 22 and the riser 1 is the second vent 32. The first vent 31 and the second vent 32 provide ventilation channels for the first group of horizontal branch pipes 21 and the second group of horizontal branch pipes 22, respectively, balancing the air pressure between the horizontal branch pipes and the riser and preventing problems such as poor drainage and backflow of odors caused by pressure imbalance. The first vent 31 vents for the water flow in the first group of horizontal branch pipes 21, and the second vent 32 vents for the water flow in the second group of horizontal branch pipes 22, making ventilation more precise and effective. This ensures pressure balance between the horizontal branch pipes and the riser, improves the stability of the drainage system, and reduces backflow of odors and blockages.

[0034] Example 5. This example shows the first vent 31, as follows: Figures 3-4 As shown, when the drainage system is in the vertical position, the first vent 31 is horizontal between the first set of horizontal branch pipes 21 and the riser 1.

[0035] The horizontally positioned first vent 31 better matches the airflow direction between the first set of horizontal branch pipes 21 and the riser 1, allowing air to flow smoothly between the two pipes and effectively balancing air pressure. The horizontally positioned vent avoids increased ventilation resistance caused by inclined placement, ensuring effective ventilation. This improves the ventilation efficiency of the first vent 31, more effectively balances the air pressure between the first set of horizontal branch pipes 21 and the riser 1, and further reduces the possibility of poor drainage and backflow of odors.

[0036] Example 6. Figure 1 , 3 As shown in Figure 4, the first vent 31 is larger than the second vent 32.

[0037] Because the first set of horizontal branch pipes 21 has a larger diameter and a larger flow rate, more air is needed to balance the air pressure, and the larger first vent 31 can provide sufficient ventilation. Conversely, the second set of horizontal branch pipes 22 has a smaller diameter and a smaller flow rate, so the smaller second vent 32 is sufficient to meet the ventilation requirements. This differentiated vent design matches the diameter and flow rate of the horizontal branch pipes, optimizing the ventilation effect. By rationally setting the vent size according to the flow rate requirements of the horizontal branch pipes, the efficiency of the ventilation system is improved, ensuring that horizontal branch pipes with different flow rates can achieve good air pressure balance.

[0038] Example 7. Figure 1 As shown, the outer wall of riser 1 is equipped with a water flow indicator 8. The water flow indicator 8 clearly indicates the direction of water flow inside riser 1. During installation and maintenance, staff can quickly and accurately determine the water flow direction based on the water flow indicator 8, ensuring the correctness of installation and the convenience of maintenance.

[0039] Example 8. Figure 1 As shown, the two ends of the riser 1 are a straight pipe 11 at the inlet end and a straight pipe 12 at the outlet end. The straight pipe 11 at the inlet end and the straight pipe 12 at the outlet end provide a stable inlet and outlet channel for water flow. The design of the straight pipe facilitates the splicing with other drainage pipes during construction and reduces the resistance of water flow when entering and exiting the riser, so that water can enter and exit the riser smoothly and improve the smoothness of drainage.

[0040] Example 9. Figure 1 , Figure 3 As shown, the section between the inlet end 4 and the outlet end 5 of the riser 1 is an arc-shaped bend pipe 13. The arc-shaped structure of the arc-shaped bend pipe 13 makes the water flow more smoothly when turning within the riser 1, reducing the impact and turbulence at the turning point, and lowering water flow resistance and noise. The design of the arc-shaped bend pipe 13 conforms to the flow characteristics of water, allowing the water to pass smoothly through the turning point, improving drainage efficiency and noise reduction.

[0041] Example 10. Figure 1 , 3 As shown, the outlet end 5 has a recessed position 14 on the side opposite to the curved pipe 13 to narrow the pipe wall of the outlet end 5. The recessed position 14 narrows the pipe wall of the outlet end 5, which can adjust the internal diameter of the outlet end 5 to be consistent with the curved pipe 13, reduce water flow scattering, and improve drainage efficiency.

[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
