[0002] The balcony risers in residential communities built earlier are mostly mixed with rainwater and sewage, and it is common to see balcony laundry wastewater connected to rainwater risers. Most buildings do not have the conditions to build new pipes due to factors such as private courtyards, anti-theft windows, and lack of elevator operating space. When rainwater and sewage are mixed together, harmful substances in the sewage, such as organic matter, nutrients such as nitrogen and phosphorus, and various pathogens, will enter natural water bodies with rainwater runoff.

[0003] However, there are few technologies for separating rainwater and sewage from laundry wastewater on balconies in residential areas. In addition, a large number of buildings have been completed, and the scale of pipeline renovation is large and the cost is high, which affects the effectiveness of the renovation.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides Figure 1-3 The rainwater and sewage diversion valve for a mixed building riser shown in the figure includes a rainwater and sewage diversion valve 2 disposed inside a mixed building riser 1. A sewage pipe 3 is connected to one side of the mixed building riser 1. A rainwater riser 4 is located at the bottom of the rainwater and sewage diversion valve 2.

[0027] Specifically, the rainwater-sewage diversion valve 2 is placed below the sewage pipe 3 and above the rainwater riser 4. The rainwater-sewage diversion valve 2 includes a valve body 21, which is arranged on the inner wall of the rainwater riser 4. A rubber sealing ring 22 is provided on the outer wall of the valve body 21. The rubber sealing ring 22 is placed between the valve body 21 and the inner wall of the rainwater riser 4. A magnetic valve 23 is provided at the bottom of the valve body 21. A gate 24 is fixed in the middle of the magnetic valve 23. A cable guide assembly 5 is provided at the input end of the valve body 21.

[0028] Reference Figure 2-3 A gate plate 2 31 is provided at the entrance of the sewage pipe 3, a cable 6 is connected between the gate plate 1 24 and the gate plate 2 31, the cable 6 is matched with the cable guide assembly 5, and the switching states of the magnetic valve 23 and the gate plate 2 31 are opposite.

[0029] Specifically, the cable guide assembly 5 includes two sections of support rods 51 connected to the inner wall of the valve body 21, and the middle parts of the two sections of support rods 51 are commonly connected to a guide ring 52. The cable 6 passes through the guide ring 52 and is respectively connected to the gate plate 1 24 and the gate plate 2 31.

[0030] Specifically, the support rod 51 is installed in the middle of the valve body 21, and the guide ring 52 is concentrically arranged inside the valve body 21. One end of the cable 6 is fixed to the upper center part of the gate plate 2 31, and the other end is fixed to the center position of the gate plate 1 24.

[0031] Specifically, one side of the magnetic valve 23 is connected to the bottom of the valve body 21 through a connecting seat 25, and the shape of the magnetic valve 23 matches the bottom of the valve body 21, and the bottom of the valve body 21 is an inclined surface.

[0032] Specifically, the second gate plate 31 is connected to the inlet of the sewage pipe 3 through the second connecting seat 32 , and the overall size of the second gate plate 31 matches the cross-sectional size of the sewage pipe 3 .

[0033] Specifically, an inspection port 7 is further provided on one side of the building hybrid riser 1 .

[0034] In this embodiment, the valve body 21 of the rainwater and sewage diversion valve 2 is installed on the inner wall of the rainwater riser 4, ensuring that the rubber sealing ring 22 on the outer wall of the valve body 21 is tightly fitted between the valve body 21 and the inner wall of the rainwater riser 4. This ensures the sealing of the valve body 21 during installation, preventing subsequent leakage of rainwater or sewage.

[0035] Specifically, the gate plate 2 31 is connected to the inlet of the sewage pipe 3 through the connecting seat 2 32. Since the overall size of the gate plate 2 31 matches the cross-sectional size of the sewage pipe 3, it is necessary to ensure that the gate plate 2 31 can completely cover the inlet of the sewage pipe 3 and can be flexibly opened and closed during installation.

[0036] Specifically, one end of the cable 6 is fixed to the upper center portion of gate plate 2 31, and the other end is fixed to the center of gate plate 1 24 (gate plate 1 24 is fixed to the middle of the magnetic valve 23). The cable 6 is then passed through the guide ring 52 in the cable guide assembly 5. The cable 6 connection must be tight enough to ensure that it is neither too loose to cause asynchronous movement of gate plates 1 24 and 2 31, nor too tight to affect their normal opening and closing movement.

[0037] Specifically, the magnetic valve 23 is connected to the bottom of the valve body 21 through the connecting seat 25. Since the shape of the magnetic valve 23 matches the bottom (inclined surface) of the valve body 21, it is necessary to ensure that the magnetic valve 23 can fit tightly to the bottom of the valve body 21 to ensure its sealing and normal operation.

[0038] Specifically, an inspection port 7 is provided on one side of the building mixed riser 1 , and the location of the inspection port 7 should facilitate subsequent inspection, maintenance, and other operations on components such as the rainwater and sewage diversion valve 2 .

[0039] In this embodiment, when rainwater flows through the rainwater riser 4 and reaches the rainwater and sewage diversion valve 2, the magnetic valve 23 is in the open state (assuming the initial state is the rainwater discharge state). Since the opening and closing states of the magnetic valve 23 and the second gate 31 are opposite, the second gate 31 is in the closed state at this time.

[0040] Rainwater can flow smoothly downward through the open magnetic valve 23 and avoid entering the sewage pipe 3. As the magnetic valve 23 opens, gate 1 24 moves upward with it, while gate 2 31 remains closed thanks to the pull of the cable 6. Guided by the guide ring 52 of the cable guide assembly 5, the cable 6 steadily transmits force, ensuring coordinated movement of gates 1 24 and 2 31.

[0041] When sewage needs to be discharged, magnetic valve 23 closes. During this process, gate 1 24 moves downward, and gate 2 31 opens upward, pulled by cable 6. Sewage can then flow into sewage pipe 3 through the open inlet, avoiding flow into rainwater standpipe 4.

[0042] In this embodiment, because the cable 6 is precisely guided by the cable guide assembly 5, the first and second gates 24 and 31 can achieve precise, synchronous, counter-rotating motion. For example, when the magnetic valve 23 is open 10 centimeters, the second gate 31 can accurately close the entrance to the sewage pipe 3, preventing sewage from mixing with rainwater. Conversely, when the magnetic valve 23 is closed, the second gate 31 can fully open the entrance to the sewage pipe 3, allowing sewage to flow smoothly into the sewage pipe 3.

[0043] Specifically, during the entire rainwater and sewage discharge process, the switching states of the magnetic valve 23 and the gate 2 31 are always opposite. This stable working mode can continuously ensure the accuracy of rainwater and sewage diversion and avoid the occurrence of rainwater and sewage mixing.

[0044] In this embodiment, the rubber seal 22 between the valve body 21 and the inner wall of the rainwater riser 4 effectively prevents leakage when rainwater or sewage flows through. For example, when the water pressure in the rainwater riser 4 is high, the rubber seal 22 can withstand the water pressure and prevent rainwater from seeping out of the gap between the valve body 21 and the inner wall of the riser 4.

[0045] Specifically, the magnetic valve 23 matches the sloped shape of the bottom of the valve body 21, and when the magnetic valve 23 is closed, it can fit tightly to prevent the leakage of rainwater or sewage. For example, when sewage is discharged, closing the magnetic valve 23 can effectively prevent sewage from flowing into the rainwater riser 4.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
