Description

Technical Field

[0001] This utility model relates to the field of building drainage riser technology, and in particular to a micro-vortex flow Suvitu component for building drainage. Background Technology

[0002] Currently, in the field of building drainage, with the rapid development of urbanization, the limited land area and dense population of cities, along with the increasing proportion of high-rise and super high-rise residential buildings, have significantly increased the pressure on building drainage systems. Sewage in building drainage systems is not a full-flow process and contains a certain amount of solid waste such as feces, forming a complex three-phase flow of water, air, and solids. The unstable flow pattern in some areas during drainage leads to a complex drainage process, causing drastic changes in energy and pressure as the water falls within the drainage riser, making the flow rate issue an urgent problem to solve. The existing Suvito structure is no longer sufficient to meet the high flow rate requirements with the development of modern technology, necessitating a series of hydraulic structural optimizations.

[0003] For special single-pipe systems, several issues still need to be addressed: First, regarding the vortex structure, maintaining good water-liquid separation and ensuring unobstructed flow in the intermediate gas channel during two-phase drainage is crucial for improving flow rates. Existing gas channels are prone to blockage due to water backflow, affecting high-flow drainage. Second, the original Suvito structure is no longer adequate for high-flow requirements due to technological advancements, necessitating a series of hydraulic structural optimizations. The bottom merging pipe is prone to water blockage when closing the flow between the upper pipe and the horizontal branch pipe, further impacting high-flow drainage. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a micro-vortex Suvitt tube for building drainage, thereby solving the problems of low drainage flow caused by the gas channel of the Suvitt tube being blocked due to backflow and the bottom confluence pipe being prone to water blockage.

[0005] The technical problem solved by this utility model can be achieved by the following technical solution: A micro-vortex flow Suvitu component for building drainage includes an upper riser, a middle diversion pipe, and a bottom merging pipe. The middle diversion pipe includes a horizontal pipe water flow cavity and a riser water flow cavity. The upper end of the riser water flow cavity is connected to the upper riser, and the lower end of the riser water flow cavity is connected to the lower merging pipe. A horizontal branch pipe is connected to the side of the horizontal pipe water flow cavity. A partition is provided between the horizontal pipe water flow cavity and the riser water flow cavity. A gas channel is provided between the upper end of the horizontal pipe water flow cavity and the riser water flow cavity. The gas channel is located above the partition. The lower end of the horizontal pipe water flow cavity is connected to the riser water flow cavity.

[0006] like Figure 2 As shown, the upper riser has a slight counterclockwise rotation. A guide rib is provided at the upper end of the upper riser, and the guide rib's direction is consistent with the slight counterclockwise rotation of the upper riser's body.

[0007] The end of the gas channel that connects to the horizontal pipe water flow chamber is higher than the end that connects to the vertical pipe water flow chamber, and the slope of the gas channel is 10°-15°.

[0008] A drainage ramp is provided on the upper side wall of the bottom confluence pipe, located on the wall surface impacted by the water flow from the middle diversion pipe. The height of the drainage ramp is 5-8 mm.

[0009] The side of the horizontal water flow chamber is connected to a first horizontal branch pipe and a second horizontal branch pipe. The first horizontal branch pipe is located above the second horizontal branch pipe, and the diameter of the first horizontal branch pipe is larger than the diameter of the second horizontal branch pipe.

[0010] The closest vertical distance between the first horizontal branch pipe and the second horizontal branch pipe is 30-40mm.

[0011] The diameter of the first horizontal branch pipe is 110 mm, and the diameter of the second horizontal branch pipe is 75 mm.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Unlike traditional special single-pipe fittings that mainly focus on smooth water flow, this micro-vortex Suvitt fitting combines the flow splitting principle of Suvitt and the rotational exhaust principle of the vortex, which can meet different flow requirements from small flow rate to large flow rate.

[0014] 2. The gas channel of this utility model has an anti-backflow function, which can prevent water from overflowing from the upper riser to the middle diversion pipe and blocking the gas channel. It maintains good water-liquid separation during the two-phase flow drainage process and improves the drainage capacity of the Suvito unit.

[0015] 3. A drainage slope is provided on the wall surface at the upper end of the bottom confluence pipe to prevent water from impacting the wall surface and then flowing upwards to form a water tongue with the horizontal branch pipe, thus preventing water blockage and improving the drainage capacity of the Suvito fitting.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Combined with appendix Figures 1 to 3 As shown, this embodiment discloses a micro-vortex flow Suvitu device for building drainage, including an upper riser 1, a middle branch pipe 2, and a bottom confluence pipe 3. The middle branch pipe 2 includes a horizontal pipe water flow chamber 21 and a riser water flow chamber 22. The upper end of the riser water flow chamber 22 is connected to the upper riser 1, and the lower end of the riser water flow chamber 22 is connected to the lower confluence pipe 3. A horizontal branch pipe is connected to the side of the horizontal pipe water flow chamber 21. A partition 9 is provided between the horizontal pipe water flow chamber 21 and the riser water flow chamber 22. A gas channel 5 is provided between the upper end of the flow chamber 21 and the riser water flow chamber 22. The gas channel 5 is located above the partition 9. The lower end of the horizontal pipe water flow chamber 21 is connected to the riser water flow chamber 22. The upper riser 1 is connected to the upper drainage riser and receives the confluence of the upper riser. The middle branch pipe 2 increases the water passage cross section and leaves enough water and air channels. At the same time, the partition separates the upper riser drainage and the horizontal branch pipe drainage to prevent the generation of water tongue. The bottom confluence pipe 3 closes the water flow of the upper riser and the horizontal branch pipe.

[0023] The upper riser 1 connects to the upper drainage riser, receiving the confluence of the upper riser. The body of the upper riser 1 is slightly twisted counterclockwise to ensure the water flow is in a micro-vortex state. A guide rib 4 is provided at the upper end of the upper riser 1, and the guide rib 4 is aligned with the counterclockwise slight twist of the upper riser 1 body to ensure the water flows downwards in a counterclockwise rotation. The micro-vortex Suvitt tube device combines the flow-dividing principle of the Suvitt tube and the rotational exhaust principle of the hydrocyclone, and can meet different flow regime requirements from small to large flow rates.

[0024] The gas channel 5 is inclined to ensure water-air balance. One end of the gas channel 5 connecting to the horizontal pipe water flow chamber 21 is higher than the end connecting to the vertical pipe water flow chamber 22. The inclination slope of the gas channel 5 is 10°-15°. This inclined design of the gas channel 5 has an anti-backflow effect, preventing water from flowing back from the upper vertical pipe 1 to the middle branch pipe 2 from clogging the gas channel 5, thus improving the drainage capacity of the pipe fittings. Combined with finite element fluid simulation analysis and actual experiments, it can be concluded that the gas channel 5 between the horizontal branch pipe and the vertical pipe can reduce the pressure fluctuation of the horizontal branch pipe by about 5-10%, indirectly increasing the system flow rate.

[0025] A drainage ramp 8 is provided on the upper side wall of the bottom confluence pipe 3. The drainage ramp 8 is located on the wall surface on the side where the water flow from the middle diversion pipe impacts. The height of the drainage ramp 8 is 5-8mm. This reduces the impact of the water flow in the riser water cavity 22 of the middle diversion pipe 2 on the side wall, prevents the water flow from impacting one side wall and then flowing upwards to form a water tongue with the horizontal branch pipe, prevents water blockage, and improves the drainage capacity of the pipe fitting.

[0026] The side of the horizontal water flow cavity 21 is connected to a plurality of first horizontal branch pipes 6 and a plurality of second horizontal branch pipes 7. The first horizontal branch pipes 6 are located above the second horizontal branch pipes 7, and the diameter of the first horizontal branch pipes 6 is larger than the diameter of the second horizontal branch pipes 7.

[0027] The diameter of the first horizontal branch pipe 6 is 110mm, and the diameter of the second horizontal branch pipe 7 is 75mm. The first horizontal branch pipe 6 can be used to connect to the drain outlet of the toilet, and the second horizontal branch pipe 7 can be used to connect to the drain outlet of the shower floor drain.

[0028] The vertical distance between the first horizontal branch pipe 6 and the second horizontal branch pipe 7 is 30-40mm at the closest point. Compared with the traditional Suvito structure, the vertical distance between the two horizontal branch pipe openings is reduced, which facilitates the construction of the interlayer while expanding the drainage space of the bottom confluence pipe 3.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
