[0034] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0035] This invention provides a flow guide tee 100 for a non-spiral ribbed drainage system, such as... Figure 1 As shown, it includes an upper branch pipe 110, a lower branch pipe 120, and a horizontal branch pipe 130.

[0036] A flow divider 140 is provided on the upper branch pipe 110. The flow divider 140 is located above the horizontal branch pipe 130. The flow divider 140 includes an intersecting first flow divider 141 and a second flow divider 142. The top ends of the first flow divider 141 and the second flow divider 142 overlap.

[0037] An expansion area 150 is provided below the flow divider 140, and the expansion area 150 and the flow divider 140 are respectively located on both sides of the flow guide tee 100.

[0038] An eccentric flow guide zone 160 is provided at the connection between the horizontal branch pipe 130 and the lower branch pipe 120, and the eccentric flow guide zone 160 is located below the expansion zone 150.

[0039] When the non-spiral ribbed drainage system tee 100 provided in this application is used in a drainage system, the water descending from the upper branch pipe 110 will be diverted by the diverter 140 and enter the expansion zone 150 below the diverter 140. The water flowing into the horizontal branch pipe 130 can form a vortex under the influence of the Earth's rotation and the initial velocity of the water flow in the horizontal direction. The vortex is deflected by the eccentric guide zone 160 and continues to form a vortex with the water from the upper branch pipe 110 in the pipe connected to the lower branch. An air core is formed in the middle of the vortex. Without the need for a spiral pipe, it can achieve air-water separation and reduce airflow resistance, while reducing the interference of the descending water flow in the upper branch pipe 110 on the water inlet of the horizontal branch pipe 130. When applied to a drainage system, it can improve the drainage capacity of the drainage system.

[0040] Specifically, the diverter 140 in this application is disposed on the inner wall of the upper branch pipe 110 and protrudes inward to divert the water flow. It includes a first diverter 141 and a second diverter 142, the purpose of which is to divert the water flow to the expansion zone 150 and reduce interference with the water inlet of the horizontal pipe 300. In some embodiments, the first diverter 141 and the second diverter 142 can be symmetrically arranged with the plane containing the centers of the upper branch pipe 110 inlet, the lower branch pipe 120 inlet, and the horizontal branch pipe 130 inlet as the symmetrical plane; in some embodiments, the first diverter 141 and the second diverter 142 can be flat or have a certain curvature.

[0041] In an optional embodiment, the included angle between the first shunt plate 141 and the second shunt plate 142 is 40°-70°.

[0042] If the angle between the first diverter 141 and the second diverter 142 is too large, the resistance to the water coming from the upper branch pipe 110 will be too great, which will not be conducive to improving the drainage capacity and will increase the drainage noise. If the angle between the first diverter 141 and the second diverter 142 is too small, it will not be able to effectively reduce the interference of the water coming from the upper branch pipe 110 to the water coming from the horizontal branch pipe 130, which may cause a water block at the tee, thereby affecting or even reducing the drainage capacity.

[0043] The present invention also provides a non-spiral ribbed drainage system, such as... Figure 2 As shown, it includes a riser 200, on which two or more flow guide tees 100 for the non-spiral ribbed drainage system described in the aforementioned embodiments are provided.

[0044] In this embodiment, when the non-spiral rib drainage system drains water, the water flows from the horizontal branch pipe 130 into the vertical pipe 200 through the horizontal pipe 300 branch of the guide tee 100. Due to the Earth's rotation and the initial velocity of the water flow in the horizontal direction, the Coriolis force, i.e., the deflection force, is generated, which causes the water flow to form a vortex effect at the outlet of the horizontal branch pipe 130. The outlet of the horizontal pipe 300 of the guide tee 100 has an eccentric guide zone 160, which allows the water flow to be deflected along the eccentric guide zone 160 and enter the lower branch pipe 120 and the vertical pipe 200 in sequence. When the water flows downward, the vortex effect is further enhanced under the action of inertia and gravity, forming an annular water film flowing downward with an air core in the middle, ensuring the ventilation effect. Furthermore, when the water flow inside the riser 200 forms a vortex and moves downward into the next guide tee 100, the water flow still spirals along the wall. Under the action of the flow divider 140 inside the guide tee 100, the water flow moves away from the horizontal branch pipe 130 along the flow divider 140 and enters the expansion zone 150. The water coming from the horizontal branch pipe 130 will not be disturbed by the water flow from the riser 200, thereby avoiding the formation of a water block at the intersection of the horizontal pipe 300 and the riser 200, and ensuring smooth ventilation.

[0045] In an optional embodiment, a wind cap 700 is provided at the top of the riser 200;

[0046] And / or, the bottom end of the riser 200 is sequentially provided with a diversion direct pipe 400, a bottom discharge elbow 500 and a discharge pipe 600.

[0047] Water flows downward in riser 200 and enters diversion direct pipe 400. Diversion direct pipe 400 is provided with a diversion structure. The diversion structure can have the same structural dimensions as the diversion plate 140 in guide tee 100. It is set on the inner wall of diversion direct pipe 400 near discharge pipe 600, so that water flows along the inner wall opposite to the diversion structure in bottom discharge elbow 500 to the bottom of discharge pipe 600. This creates an air passage above the water flow in discharge pipe 600 and to the side of the water flow in bottom discharge elbow 500.

[0048] The wind cap 700 installed at the top of the riser 200 can be a non-powered wind cap 700. The installation of the wind cap 700 helps to further improve the exhaust effect in the system.

[0049] In an optional embodiment, a horizontal pipe 300 is connected to the horizontal branch pipe 130, and the axes of the horizontal pipe 300 and the vertical pipe 200 corresponding to each flow guide tee 100 are coplanar. The connection between the upper branch pipe 110, the lower branch pipe 120 and the horizontal branch pipe 130 protrudes from the plane where the horizontal pipe 300 and the vertical pipe 200 are located.

[0050] The horizontal pipes 300 corresponding to different tees can be parallel or non-parallel, and the axes of the horizontal pipe 300 and the riser 200 corresponding to each guide tee 100 are coplanar. In practical applications, the number of horizontal pipes 300 is related to the number of floors, and usually one horizontal pipe 300 corresponds to each floor.

[0051] In an optional embodiment, the inner diameter of the horizontal tube 300 and the vertical tube 200 is 105 mm.

[0052] In an optional embodiment, the length of the diverter 140 in the radial direction of the upper branch pipe 110 is 7mm-12mm;

[0053] And / or, the length of the diverter 140 in the axial direction of the upper branch pipe 110 is 170mm-200mm.

[0054] The diverter plate 140 has a certain length and depth so that it can divert the water flow to the expansion zone 150, reducing or even avoiding the interference of the downflow on the water coming into the horizontal branch pipe 130.

[0055] In an optional embodiment, the volume of the expansion zone 150 is increased by 8%-15% compared to the volume of the riser 200 of the same height, so as to accommodate the water flow diverted by the diverter 140, thereby reducing or even avoiding the interference of the descending water flow on the water coming from the horizontal branch pipe 130.

[0056] In an optional embodiment, the intersection of the inner wall of the expansion area 150 and plane A is an arc shape, and plane A is the plane containing the axis of the horizontal pipe 300 and the axis of the vertical pipe 200.

[0057] The radius of the arc corresponding to the intersection line is 400mm-450mm;

[0058] The arc corresponding to the intersection line is 0.2-0.3, or the total height of the expansion area 150 is 500mm-550mm.

[0059] While ensuring the increase in the cross-sectional area of ​​the expansion zone 150, the shape of the expansion zone 150 should also be reasonably designed to minimize the obstruction of water flow by the expansion zone 150, so as to improve the drainage capacity of the drainage system.

[0060] In an optional embodiment, the eccentric guide region 160 is arc-shaped, the radius of the arc corresponding to the eccentric guide region 160 is 150mm-200mm, the arc degree of the arc corresponding to the eccentric guide region 160 is 0.8-0.85, and the angle between the plane containing the axis of the eccentric guide region 160 and the horizontal plane is 41.5-46°.

[0061] The eccentric guide zone 160 is designed to adapt to and enhance the vortex formed by the water coming from the horizontal branch pipe 130, so that the water can still vortex downward after it is transferred to the riser pipe 200.

[0062] Example 1

[0063] One embodiment of this application provides a non-spiral ribbed drainage system, such as... Figure 1 and Figure 2 As shown, the inner diameter of both the horizontal pipe 300 and the vertical pipe 200 is 110mm;

[0064] The depth of the flow divider 140 is 8mm, the angle between the first flow divider 141 and the second flow divider 142 is 60°, and the height is 1850mm.

[0065] The intersection of the inner wall of the expansion zone 150 and plane A is an arc with a radius of 425mm and an arc degree of 0.25. The total height of the expansion zone is 530mm.

[0066] The eccentric guide zone 160 is arc-shaped with a radius of 150-200mm and an arc degree of 0.82. The angle between the plane containing the axis of the eccentric guide zone 160 and the horizontal plane is 44°.

[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
