[0039] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0040] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0041] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] The vertical pipe drainage system is an essential drainage system in buildings, which is used to drain sewage from the roof and sewage in the floors.

[0043] Currently, the common special single-riser drainage systems mainly include three categories: the first category is the drainage system with special fittings only, such as the Suvito single-riser system and the GB-type reinforced cyclone single-riser system; the second category is the drainage system with special pipe materials only, such as the high-rib reinforced internal spiral system; the third category is the drainage system with specially customized fittings and pipe materials.

[0044] However, the drainage capacity of the above three types of single-riser drainage systems is weak and the drainage speed is slow.

[0045] In order to solve the above problems, an embodiment of the present application provides a reinforced cyclone single riser drainage system. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.

[0046] Figure 1 It is a schematic diagram of a reinforced cyclone single riser drainage system provided in one embodiment of the present application; Figure 2 It is a schematic diagram of fixing a single vertical pipe 100 provided in one embodiment of the present application.

[0047] Reference Figure 1 and Figure 2 As shown, the embodiment of the present application provides a reinforced cyclone single-pipe drainage system, including a single-pipe 100, a drainage horizontal main pipe 200, a pressure relief pipe 300 and a ventilation assembly 400. The single-pipe 100 is vertically fixed through the floor 700 in the building, and the drainage horizontal main pipe 200 is horizontally arranged. One end of the single-pipe 100 is connected to the ventilation assembly 400, the other end of the single-pipe 100 is connected to the drainage horizontal main pipe 200, and the other end of the drainage horizontal main pipe 200 is connected to the sewage collection device. One end of the pressure relief pipe 300 is connected to the single-pipe 100, and the other end of the pressure relief pipe 300 is connected to the drainage horizontal main pipe 200. The single-pipe 100, the drainage horizontal main pipe 200 and the pressure relief pipe 300 form a loop, so that the water pressure in the entire drainage system can be balanced, so that the drainage horizontal main pipe 200 can flow away quickly, thereby improving the drainage capacity and drainage speed of the entire system.

[0048] The single vertical pipe 100 is used to connect the drainage points of each floor, reduce the noise generated by the drainage of the branch pipe, and adjust the water flow state. The pressure relief pipe 300 can transmit the gas pressure generated by the hydraulic jump of the water flow in the drainage horizontal main pipe 200 to the drainage vertical pipe, balancing the pressure difference between the single vertical pipe 100 and the drainage horizontal main pipe 200. The ventilation component 400 is mainly used to discharge the harmful gas in the single vertical pipe 100, destroy the transverse diaphragm in the single vertical pipe 100, and prevent the wall spiral flow in the single vertical pipe 100 from becoming a water film flow, or even forming a water plug flow to reduce the drainage capacity of the entire system.

[0049] In addition, in order to improve the drainage capacity of the drainage system, the diameter of the drainage horizontal main pipe 200 is larger than the diameter of the single vertical pipe 100, and the drainage horizontal main pipe 200 is connected to the single vertical pipe 100 through a double-diameter connecting piece 500. The double-diameter connecting piece 500 includes a first end and a second end, the diameter of the first end is larger than the diameter of the second end, the first end is connected to the end of the single vertical pipe 100, and the second end is connected to the end of the drainage horizontal main pipe 200. In addition, the drainage horizontal main pipe 200 and the single vertical pipe 100 can be connected by two 45° elbows or 90° reducer elbows to reduce the resistance of the water flow in the single vertical pipe 100 and reduce the scouring effect of the water flow on the drainage horizontal main pipe 200. The distance between the connection point of the pressure relief pipe 300 and the drainage horizontal main pipe 200 and the drainage vertical pipe is not less than 2 meters. The distance between the access point of the pressure relief pipe 300 in the single vertical pipe 100 and the drainage horizontal main pipe 200 is also not less than 2 meters.

[0050] In addition, in order to improve the stability of the entire drainage system, the enhanced vortex single-tube drainage system also includes a support seat 600, which is fixedly arranged below the dual-diameter connecting piece 500, and the support seat 600 is in contact with the dual-diameter connecting piece 500, and the support seat 600 is used to support the dual-diameter connecting piece 500.

[0051] Figure 3 It is a cross section of a single vertical pipe 100 provided in one embodiment of the present application.

[0052] For example, refer to Figure 3 As shown, the inner wall of the single vertical pipe 100 is provided with a spiral groove 110 spiraling downward, thereby increasing the resistance of water flowing in the single vertical pipe 100, reducing the occurrence of funnel-shaped water flow phenomenon, and effectively preventing the pressure fluctuation in the entire drainage system from causing the water seal of the sanitary ware connected to the drainage system to be damaged. In addition, the material of the single vertical pipe 100 is configured as a hard polyvinyl chloride material. Before installation, after the ribs in the single vertical pipe 100 are chamfered, they are connected by electric melting or hot melting.

[0053] Continue to refer to Figure 1 As shown, the pressure relief pipe 300 includes a first pipe section 310, a second pipe section 320, a third pipe section 330, a fourth pipe section 340, a fifth pipe section 350 and a sixth pipe section 360. The first pipe section 310, the second pipe section 320, the third pipe section 330, the fourth pipe section 340, the fifth pipe section 350 and the sixth pipe section 360 are connected end to end in sequence. The first pipe section 310 is connected to the single vertical pipe 100, and the sixth pipe section 360 is connected to the drainage horizontal main pipe 200. Exemplarily, the first pipe section 310 is connected to the upward inclined single vertical pipe 100 at a 45-degree angle, the second pipe section 320 is configured as a 90-degree connecting pipe, the third pipe section 330 is configured as a straight pipe, passes through the floor 700 and is vertically arranged, the fourth pipe section 340 is configured as a 90-degree connecting pipe, the fifth pipe section 350 is configured as a straight pipe and is horizontally arranged, and the sixth pipe section 360 is connected to the drainage horizontal main pipe 200 at a 45-degree angle.

[0054] Figure 4 yes Figure 1 A schematic diagram of the connection of the ventilation assembly 400 of the enhanced cyclone single riser drainage system;

[0055] Figure 5 It is a schematic diagram of the structure of a ventilation assembly 400 provided in one embodiment of the present application.

[0056] Reference Figure 4 and Figure 5 As shown, exemplarily, the ventilation assembly 400 includes a telescopic vent pipe 410, a reducing connecting pipe 420 and a vent cap 430. One end of the single vertical pipe 100 away from the drainage horizontal main pipe 200 is connected to one end of the telescopic vent pipe 410, the other end of the telescopic vent pipe 410 is connected to one end of the reducing connecting pipe 420, and the other end of the reducing connecting pipe 420 is connected to the vent cap 430. The ventilation assembly 400 can form an upward suction force in the single vertical pipe 100, effectively preventing the formation of water film flow in the single vertical pipe 100 and reducing the drainage capacity, and can also discharge harmful gases in the system.

[0057] In some examples, the ventilation assembly 400 includes a telescopic vent pipe 410, a reducing connecting pipe 420 and a vent cap 430; one end of the single vertical pipe 100 away from the drainage horizontal main pipe 200 is connected to one end of the telescopic vent pipe 410, the other end of the telescopic vent pipe 410 is connected to one end of the reducing connecting pipe 420, and the other end of the reducing connecting pipe 420 is connected to the vent cap 430. The vent cap 430 is combined with the air inlet hole on the outdoor household well cover of the building to ventilate the indoor drainage system.

[0058] The power of natural ventilation of the vent cap 430 comes from wind pressure, thermal pressure, and outdoor wind speed. Wind pressure mainly refers to the static pressure difference between the inside and outside of the system caused by the outdoor wind acting on the building's external protective structure (outside the drainage system). The magnitude of wind pressure is proportional to the square of the outdoor air flow rate at the vent cap 430.

[0059] Thermal pressure is mainly caused by the temperature difference between the gas inside and outside the system. Indoor drainage has a certain temperature, which causes the air in the drainage system to become less dense after being heated. The density difference between the gas inside and outside the system generates thermal pressure under a certain height difference. The thermal pressure is proportional to the height difference from the drainage point to the top of the extended ventilation pipe and the difference in gas density inside and outside the system.

[0060] The outdoor wind speed acts as the driving force for the rotation of the vent cap 430, which helps to remove harmful gases in the system. According to relevant experience, when the outdoor wind speed of the Φ300 vent cap 430 is 1m / s, the ventilation volume can reach 285m 3 / h or more.

[0061] Generally, the diameter of the indoor single vertical pipe 100 is not larger than DN150, and a concentric reducing pipe fitting can be used to connect the single vertical pipe 100 with the unpowered vent cap 430.

[0062] In order to ensure the ventilation effect of the vent cap 430, the installation height of the vent cap 430 is generally higher than the roof parapet (or the upper edge of other shielding objects) by more than 300 mm.

[0063] like Figure 5 As shown, exemplarily, the vent cap 430 includes a fixed flange 431, a ventilation pipe 432 and a turbine-type natural ventilation assembly 433, the fixed flange 431 is used to fix the turbine-type natural ventilation assembly 433, the reducing connecting pipe 420 is connected to one end of the ventilation pipe 432 away from the telescopic ventilation pipe 410, and the other end of the ventilation pipe 432 is connected to the turbine-type natural ventilation assembly 433.

[0064] Continue to refer to Figure 3 As shown, the enhanced cyclone single pipe drainage system also includes a drainage connecting pipe 800, one end of which is connected to the building drainage component, and the other end of which is connected to the single pipe 100, and a cyclone is arranged inside the drainage connecting pipe 800. The single pipe 100 and the cyclone pipe can be connected by a sliding buckle. The connecting end face is perpendicular to the axis of the single pipe 100, and is provided with a special flexible sealing ring, and the outer side is clamped by a 180° rotating sliding buckle clamp.

[0065] The drainage connecting pipe 800 can be a three-way or four-way pipe. After passing through the cyclone, the water in the building drainage assembly flows into the single vertical pipe 100 along the inner wall at a certain speed, forming a wall-attached spiral flow in the hollow vertical pipe.

[0066] Figure 6 is a first schematic diagram of a drainage connecting pipe 800 provided in the first embodiment of the present application; Figure 7 is a second schematic diagram of the drainage connecting pipe 800 provided in the first embodiment of the present application; Figure 8 is a first schematic diagram of a drainage connecting pipe 800 provided in the second embodiment of the present application; Fig. 9 is a second schematic diagram of the drainage connecting pipe 800 provided in the second embodiment of the present application; Fig.10 is a first schematic diagram of a drainage connecting pipe 800 provided in the third embodiment of the present application; Fig.11 This is a second schematic diagram of the drainage connecting pipe 800 provided in the third embodiment of the present application.

[0067] Reference Figures 6 to 11 As shown, the drainage connecting pipe 800 can be a three-way pipe fitting, a 90° diversion four-way pipe fitting, or a 180° diversion four-way pipe fitting.

[0068] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
