Description

Technical Field

[0001] The utility model relates to the technical field of Suweto drainage systems, in particular to a reversing connection elbow for converting a vertical direction into a horizontal direction. Background Art

[0002] When the riser of the Suweto drainage system is draining water from high to low, the water flow needs to be turned from a vertical downward state to a horizontal state due to the building structure being offset in the middle layer or already at the bottom layer, or because the water flow rate needs to be reduced. At this time, a double-tube pressure relief pipe system is required, such as Figure 1 As shown, the pressure relief pipe system includes a connected riser 10 and a cross pipe 20 and a pressure relief pipe 30 connected between the side of the riser 10 and the upper surface of the cross pipe 20. The pressure relief pipe 30 serves as a bypass of the riser 10 to achieve water-gas separation, that is, when water vapor passes through the connection between the riser 10 and the pressure relief pipe 30, the portion of the riser 10 below the connection is used for drainage, while the pressure relief pipe 30 is used for exhaust, so as to achieve a better drainage state.

[0003] The above-mentioned double-tube structure requires an additional pressure relief pipe 30 for connection, which makes the structure of the pressure relief pipe system complicated, and has the disadvantages of being difficult to install and occupying space. Utility Model Content

[0004] The utility model aims to provide a reversing connection elbow for converting from vertical to horizontal direction, which can be applied to the Suweto drainage system to solve the disadvantages of the double-pipe structure.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A reversing connection elbow for converting from vertical to horizontal direction comprises a bend pipe body; a vertical pipe interface and a horizontal pipe interface are respectively arranged at both ends of the bend pipe body; a turning section of the bend pipe body is between the vertical pipe interface and the horizontal pipe interface, an outer turning radius of the turning section is greater than 150 mm, and in a radial cross section of the turning section, the outer side of the turning section is a straight edge.

[0007] The radius of the curved pipe body is 55 mm.

[0008] The length of the straight side of the turning section is the largest in the middle of the turning section and gradually decreases toward the two end positions of the turning section.

[0009] After adopting the above technical solution, the utility model has the following technical effects:

[0010] Through the above scheme, after the reversing connecting elbow of the utility model is applied to the Sueto drainage system and connected with the vertical pipe and the horizontal pipe, there is no need to install a pressure relief pipe, which makes the structure more concise and has the advantages of easy installation and small space occupation. The reversing connecting elbow can realize the diversion of water flow from vertical row to horizontal row. In conjunction with the Sueto drainage system, when the vertical pipe is draining, a continuous air column can be formed in the vertical pipe, the elbow body and the horizontal pipe, ultimately ensuring smooth gas flow between the pipe bodies, the air pressure can be kept balanced everywhere, the air flow is stable, and the same better drainage effect as the double-pipe structure is achieved.

[0025] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0026] refer to Figures 2 to 12 As shown, the utility model discloses a reversing connection elbow for converting from vertical to horizontal direction, comprising an arc-shaped elbow body 1;

[0027] The two ends of the elbow body 1 are respectively provided with a vertical pipe interface 11 and a horizontal pipe interface 12, and the vertical pipe interface 11 and the horizontal pipe interface 12 are respectively used to connect the vertical pipe 10 and the horizontal pipe 20;

[0028] The bend section 13 of the elbow body 1 is located between the vertical pipe interface 11 and the horizontal pipe interface 12. The outer bend radius R of the bend section 13 is greater than 150 mm, and in the radial cross section of the bend section 13, the outer side of the bend section 13 is a straight edge 131, see Figures 8 to 10 The straight edge 131 makes the cross section of the turning section 13 approximately D-shaped.

[0029] Through the above scheme, after the reversing connecting elbow of the utility model is applied to the Sueto drainage system and connected with the vertical pipe 10 and the horizontal pipe 20, there is no need to install a pressure relief pipe, which makes the structure more concise and has the advantages of easy installation and small space occupation. The reversing connecting elbow can realize the diversion of water flow from vertical row to horizontal row. In conjunction with the Sueto drainage system, when the vertical pipe 10 drains water, a continuous air column can be formed in the vertical pipe 10, the elbow body 1 and the horizontal pipe 20, ultimately ensuring that the gas flow between the pipe bodies is smooth, the air pressure can be kept balanced everywhere, the air flow is stable, and the same better drainage effect as the double-pipe structure is achieved.

[0030] In addition, the drainage system using the utility model can also have the following advantages:

[0031] (1) When the whole drainage system is draining, the air pressure in the pipe is stable, the water seal of the toilet and floor drain is more stable, and odor or harmful gases are effectively blocked from entering the room;

[0032] (2) When the entire drainage system is at the same drainage flow rate (such as a drainage flow rate of 9.5 L / S), the air column pressure in the entire pipeline is close to atmospheric pressure;

[0033] (3) When the entire pipeline system is draining, the gas pressure inside the pipeline is close to the atmospheric pressure, and the drainage flow rate is greater.

[0034] Specific embodiments of the present utility model are shown below.

[0035] The radius of the curved pipe body 1 is 55 mm.

[0036] See also Figures 8 to 10 The length of the straight side 131 is shown, and the length of the straight side 131 of the above-mentioned turning section 13 is the largest at the middle position of the turning section 13 (i.e., the position close to 45°), and gradually decreases toward the two ends of the turning section 13. Therefore, when the swirling water in the vertical pipe 10 is directed from the vertical direction to the horizontal direction, the water flow is not easy to rotate after passing through the straight side 131 of the turning section 13 of the elbow body 1, so that the water vapor in the horizontal pipe 20 is layered up and down, and the water flow gathers at the bottom of the horizontal pipe 20 and the air gathers at the top of the horizontal pipe 20.

[0037] See also Fig.12 , where the dotted line represents water flow and the dotted line represents air, the working principle of the utility model is as follows:

[0038] In the vertical pipe 10, the water flow is vertical and swirling (a feature of the Sueto drainage system), and can flow along the wall, with air in the middle of the water flow; when the water vapor passes through the reversing connection elbow, it is converted to a horizontal direction, forming a layered water flow - air above and water below. Therefore, the turning area is the transition zone between the water and gas paths, which must not only meet the changing requirements of the water flow and air flow, but also ensure that the gas is always coherent and the water flow is smooth. Therefore, the main feature of the reversing connection elbow is that the outer side has a large turning radius R and a cross-section that is approximately D-shaped, which can achieve the above functions.

[0039] In more detail, when the water flows from the vertical direction to the bottom, when the turning radius R is large, it is conducive to smoothly directing the water flow to the horizontal direction, and it is not easy to form a water jump in front of the horizontal direction, and no water plug will be formed. The smooth water flow can ensure smooth airflow. Regarding the cross-section that is approximately D-shaped, since its straight edge 131 is on the outside of the turning section 13, when the water flow is directed from the vertical direction to the horizontal direction, the water flow is not easy to rotate, causing the water vapor directed horizontally to be stratified, that is, the horizontal water vapor is air above and water flow below.

[0040] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
