All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, the terms "upper", "lower", "front", and "rear", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The following further describes embodiments of the present invention with reference to the drawings.
Example 1:
referring to fig. 3-16, the present embodiment provides a building drain collection system that is inscribed between sewage mains drainage pipes and is in up-and-down communication with the mains drainage pipes when actually installed. The drainage pipe comprises a drainage pipe component 1, a horizontal pipe drainage component 2 communicated with the drainage pipe component 1, and a water seal component 3 communicated with the horizontal pipe drainage component 2. In the present embodiment, the sewage refers to water discharged from a toilet, and the waste water refers to water discharged from a shower, a sink, or the like.
The drain assembly 1 described with reference to fig. 3-10 comprises a first inlet conduit 11, a second inlet conduit 12, a first riser conduit 13 and a second riser conduit 14; the first water inlet pipe 11 is connected with the second water inlet pipe 12 and communicated with the inside of the first water inlet pipe, and the inner edge of the second water inlet pipe 12 is tangent to the inner edge of the first water inlet pipe 11, so that sewage can flow into the first water inlet pipe 11 along the inner wall of the second water inlet pipe 12 in an adherent manner; the first water inlet pipe 11 is connected with the first vertical pipe 13 and is communicated with the interior of the first vertical pipe, the second water inlet pipe 12 can be communicated with a toilet sewage draining exit and is used for receiving sewage of the toilet sewage draining exit, and the sewage enters the first water inlet pipe 11 along the second water inlet pipe 12. In this embodiment, the first water inlet pipe 11 and the second water inlet pipe 12 are an integrally formed structure, and the first water inlet pipe 11 and the first vertical pipe are sleeved and adhered together. In addition, an included angle of 80-100 degrees is formed between the second water inlet pipe 12 and the first water inlet pipe 11, and the second vertical pipe 14 is communicated with the main sewage discharge pipeline, so that all the sewage collected by the collecting system in the embodiment is discharged into the main sewage discharge pipeline.
Further, the pipe wall cavity 15 that the second inlet tube 12 and the first inlet tube 11 intercommunication department are the volume inflation, when sewage along second inlet tube 12 entering first inlet tube 11, the curvature radius that sewage pasted the pipe wall whirl can be increased in setting up of pipe wall cavity 15, when sewage discharge capacity is big, effectively reduce sewage discharge rate, ensure that sewage can hug closely the pipe wall whirl, avoid because of pipeline curvature radius undersize, sewage when sewage discharge capacity is big direct current discharges from the pipeline and causes the time of the drainage big noise, reduce pipeline life scheduling problem.
Further, the shape of the first water inlet pipe 11 is a funnel-shaped structure with an expanded upper end opening and a reduced lower end opening from top to bottom, the inner diameter of the upper end opening of the first water inlet pipe 11 is larger than the inner diameter of the first vertical pipe 13, and the inner diameter of the lower end opening is close to the inner diameter of the first vertical pipe 13 and can be sleeved with the first vertical pipe 13. The inner diameter of the upper end opening of the first water inlet pipe 11 is larger than the inner diameter of the first vertical pipe 13, so that the curvature radius of the sewage is increased when the sewage is attached to the wall of the pipe in a swirling mode, the swirling radius is gradually reduced when the sewage is attached to the wall of the pipe in a swirling mode, and finally the sewage enters the first vertical pipe 13 and the second vertical pipe 14 in a swirling mode and is discharged into a main sewage discharge pipeline.
Further, a pipe cover 111 is further arranged at an opening at the upper end of the first water inlet pipe 11, a pipe joint 112 is arranged on the pipe cover 111, and the pipe joint 112 is communicated with the first water inlet pipe 11 and is used for being connected with a main drainage pipeline.
Therefore, the concrete implementation manner of the building drainage collection system internally connected to the main drainage pipeline is that the upper end of the collection system, the pipe connector 112 of the drainage pipe assembly 1 is communicated with the upper main drainage pipeline, the lower end of the collection system, and the second vertical pipe 14 are communicated with the lower main drainage pipeline, so that the drainage collection system is communicated with the main drainage pipeline up and down. In this embodiment, the upper-layer main drainage pipeline refers to a part of the main drainage pipeline located on the upper side of the drainage pipe assembly 1 with respect to the three-dimensional space of the building, and the lower-layer main drainage pipeline refers to a part of the main drainage pipeline located on the lower side of the drainage pipe assembly 1.
Further, in practical use, the temperature of the sewage discharged into the first vertical pipe 13 varies according to the source, and the temperature of the sewage varies, for example, the temperature of the waste water generated by showering is higher than the temperature of normal domestic water by approximately 30 ℃, and the temperature difference of the sewage causes thermal expansion and cold contraction of the first vertical pipe 13, so that the first vertical pipe 13 extends or contracts, thereby affecting the sealing property of the connection between the upper-layer main drainage pipeline and the pipe joint 112, and therefore, in order to reduce the influence of the thermal expansion and cold contraction on the overall sealing property of the drainage pipe assembly 1 and compensate the deformation of the first vertical pipe 13 when the temperature of the sewage varies, the drainage pipe assembly 1 further comprises an expansion joint 16, and the expansion joint 16 is inserted into the pipe joint 112; the telescopic joint 16 comprises an outer layer circular pipe 161 and an inner layer circular pipe 162 which are sleeved with each other, the outer layer circular pipe 161 is communicated with an upper layer main drainage pipeline (see figure 16), the outer layer circular pipe 161 and an upper layer drainage pipe can slide relatively, and the telescopic range of the telescopic joint 16 can reach 102mm at most. In order to improve the sealing performance of the connection between the telescopic joint 16 and the upper-layer main drainage pipeline, a sealing ring 163 is arranged on the inner wall of the upper end of the telescopic joint 16.
Further, in order to avoid the upper drainage pipe sewage from whirling and entering the first water inlet pipe 11, or when sewage from the second water inlet pipe 12 whirling and entering the first water inlet pipe 11, the sewage can rush out of the second water inlet pipe 12 along the junction of the first water inlet pipe 11 and the second water inlet pipe 12, resulting in sewage convection, the drainage pipe assembly 1 in this embodiment further includes a baffle 113, the baffle 113 is disposed between the inner connection of the first water inlet pipe 11 and the second water inlet pipe 12. After the baffle 113 is arranged at the joint of the second water inlet pipe 12 and the first water inlet pipe 11, sewage in the second water inlet pipe 12 can enter the first vertical pipe 13 according to a set direction, the sewage in the first water inlet pipe 11 is prevented from reversely entering the second water inlet pipe 12, and the cyclone direction of the sewage entering the first vertical pipe 13 is the same as the cyclone direction of the sewage in the first vertical pipe 13.
Further, when the drainage pressure (the drainage pressure is, when sewage flows along the wall) of the upper-layer main drainage channel into the first water inlet pipe 11 is greater than the drainage pressure of the second water inlet pipe 12 into the first water inlet pipe, the water flow of the first water inlet pipe 11 may flow reversely into the second water inlet pipe 12. In order to avoid the above situation, the water discharging pipe assembly 1 in this embodiment further includes a pressure stabilizing film 114 disposed at the connection portion of the second water inlet pipe 12 and the first water inlet pipe 11, where the material of the pressure stabilizing film 114 is not particularly limited, and the pressure stabilizing film 114 in this embodiment is made of a flexible material. When the sewage in the second water inlet pipe 12 enters the first water inlet pipe 11, the pressure stabilizing film 114 does not influence the sewage to enter the first water inlet pipe 11 along the pipe wall cavity 15. When the drainage pressure of the first water inlet pipe 11 is greater than that of the second water inlet pipe, sewage in the first water inlet pipe 11 impacts the pressure stabilizing membrane 114, and the pressure stabilizing membrane 114 prevents the sewage in the first water inlet pipe 11 from entering the second water inlet pipe 12 due to pressure difference, so that the sewage can be stably discharged from the first vertical pipe 13 in a wall-attached rotational flow manner; when the drainage pressure in the first water inlet pipe 11 is equal to the drainage pressure of the second water inlet pipe, the pressure stabilizing membrane 114 is in a normal assembly state, and the drainage of pipeline sewage is not influenced; when the drainage pressure in the first water inlet pipe 11 is less than the drainage pressure of the second water inlet pipe, the pressure stabilizing film 114 is impacted by the sewage discharged by the second water inlet pipe 12 and is sunken inwards along the radial direction of the first water inlet pipe 11, so that the discharge space of the second water inlet pipe 12 is enlarged, and the final wall-adhering rotational flow of the sewage is ensured to be stably discharged from the first vertical pipe 13. In addition, when the discharge amount of sewage in the first water inlet pipe 11 attached to the inner wall of the first water inlet pipe 11 and the spiral flow velocity are large, the air flow is disturbed to form negative pressure suction force, and meanwhile, the drainage pressure of the pipe wall of the sewage formed by the large drainage amount to the sewage is large, when the pressure stabilizing film 114 is not arranged, because the negative pressure suction force and the drainage pressure are dispersed on the contact surface of the negative pressure airflow, the pipe wall and the sewage and cannot be mutually offset, the toilet water seal is easily caused to lose efficacy by the negative pressure suction, the arrangement of the pressure stabilizing film 114 enables the negative pressure suction force and the drainage pressure to jointly act on the pressure stabilizing film 114, and the three rigidity forces of the pressure stabilizing film 114 are mutually offset, so that the effect of reducing the air pressure fluctuation of the second water inlet pipe 12 is achieved, the system damping is increased, and the risk of the toilet water seal losing. When being the malleation in the first inlet tube 11, steady voltage membrane 114 expands along first inlet tube 11 radial outside to reach and alleviate the undulant mesh of pressure in the second inlet tube 12, increase system damping, reduce the closestool water seal and lead to the risk of losing efficacy because of the malleation splash.
Further, in the present embodiment, the first vertical pipe 13 and the second vertical pipe 14 both adopt a single vertical pipe, which can simultaneously realize the functions of water drainage and air exhaust, and significantly save the building space.
In the drainage pipe assembly 1 of the present embodiment, in order to avoid the formation of a water plug (the sewage/wastewater is usually discharged in a swirling manner close to the pipe wall, and when discharged in a swirling manner, a hollow air column is formed for discharging the waste gas, but if the sewage/wastewater is not discharged in a swirling manner close to the side wall of the first vertical pipe 13 or the second vertical pipe 14, but is directly discharged from the hollow portion of the first vertical pipe 13 or the second vertical pipe 14, and the sewage/wastewater occupies the passage for discharging the gas from the first vertical pipe 13 or the second vertical pipe 14, so that the waste gas cannot be discharged, the phenomenon of blocking the first vertical pipe 13 or the second vertical pipe 14) during drainage and exhaust, the pipe wall cavity 15 is provided, the sewage in the first vertical pipe 13 and the second vertical pipe 14 can be discharged in an adherence swirling mode when the flow is large, so that the formation of a water plug is avoided, the water discharge amount is increased, and the generation of water discharge noise is reduced.
