Preferably, in this embodiment, the included angle between the central axes of the first inlet pipe 11 and the second inlet pipe 12 is 30-60 °.
Further, when sewage/wastewater in the upper drainage pipeline enters the first water inlet pipe 11 in a swirling manner or when sewage enters the first water inlet pipe 11 from the second water inlet pipe 12 in a swirling manner 4, 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, so that sewage backflow is caused, and the drainage efficiency of the drainage pipe assembly 1 is further affected, in the embodiment, a baffle 17 is further arranged at the connecting part of the first water inlet pipe 11 and the second water inlet pipe 12. Through setting up baffle 17 after, not only can make the sewage in the second inlet tube 12 can get into first inlet tube 11 according to the direction of preset, can also block that the sewage in the first inlet tube 11 is reverse to get into in the second inlet tube 12 to the drainage efficiency in reinforcing drain pipe subassembly 1.
Further, as shown in fig. 6 to 7, the pipe cover 14 includes a connecting pipe 141, an eccentric pipe 142, a movable pipe 143, and a flow guide pipe 144, wherein the connecting pipe 141 is a circular pipe for connecting the pipe cover 14 to an upper drainage pipe, and a bottom end of the connecting pipe 141 is connected to and internally communicated with a top end of the eccentric pipe 142 for receiving sewage from the upper drainage pipe; the bottom end of the eccentric pipe 142 is connected with the top end of the movable pipe 143 and the top end of the flow guide pipe 144. Specifically, the guide pipe 144 is connected to and internally communicated with the bottom end of the eccentric pipe 142 through the hollow portion of the movable pipe 143, for receiving the sewage passing through the eccentric pipe 142. In this embodiment, the connecting pipe 141, the eccentric pipe 142, the movable pipe 143, and the flow guide pipe 144 are also integrally formed, and the integrally formed structure can reduce the possibility of leakage of sewage/wastewater from the pipe cap 14, thereby improving the sealing performance of the pipe cap 14 during the drainage process, and the manufacturing process is also simpler.
The eccentric tube 142 is an eccentric truncated cone-shaped structure with a top opening smaller than a bottom opening, the top opening is connected with the connecting tube 141, the bottom opening is simultaneously connected with the movable tube 143 and the guide tube 144, and the end surface area of the connecting tube 141 is smaller than that of the movable tube 143.
The movable tube 143 is also a circular tube and is movably connected to the tube interface 13, and the movable tube 143 may be sleeved in the tube interface 13, or the tube interface 13 may be sleeved in the movable tube 143, and in this embodiment, preferably, the movable tube 143 is sleeved in a hollow portion of the tube interface 13, and the movable tube 143 can rotate 360 ° around its own axis with respect to the tube interface 13, so that the tube cover 14 can rotate 360 ° around its own axis. During the rotation of the tube cover 14, since the eccentric tube 142 is eccentric, the top opening of the eccentric tube 142 will displace along with the rotation of the tube cover 14, of course, the connecting tube 141 connected to the top opening of the eccentric tube 142 will also be displaced (i.e. the axis of the connecting tube 141 is parallel to but not coincident with the axis of the movable tube 143, and when the movable tube 143 rotates 360 ° around its own axis, the connecting tube 141 will also rotate around the axis of the movable tube 143), so that the operator can correct the position of the connection pipe 141 according to the position of the upper drainage pipe, the position of the connection pipe 141 can be just butted with the position of the upper drainage pipe, and then the pipe cover 14 is butted with the upper layer of drainage pipe fittings to complete the installation of the drainage system in the building, so that the sewage and wastewater drainage concentrator provided by the invention can adapt to various installation scenes.
In addition, the bottom of honeycomb duct 144 cup joints with first inlet tube 11, and then with the first inlet tube 11 of sewage direction in the upper drainage pipe fitting, for avoiding sewage to take place to leak, the bottom of honeycomb duct 144 should stretch into first inlet tube 11, and certain clearance has between the part that honeycomb duct 144 stretches into in first inlet tube 11 and the inner wall of first inlet tube 11 to when making the tube cap 14 rotatory, the part that honeycomb duct 144 stretches into in the first inlet tube 11 can rotate in the hollow portion of first inlet tube 11.
Further, in order to prevent the sewage in the flow guide pipe 144 from rushing out of the flow guide pipe 144, due to the lack of the flow guiding effect of the wall of the flow guide pipe 144, the rotational flow direction of the sewage is changed, so that the sewage drops at the communication position between the second water inlet pipe 12 and the first water inlet pipe 11, and splashes water and splash, and further the drainage and exhaust functions of the first water inlet pipe 11 are affected, in this embodiment, the flow guide pipe 144 is designed to be a closing structure with an opening at the top end larger than an opening at the bottom end. After the flow guide pipe 144 is configured as above, when sewage flows into the first water inlet pipe 11 from the flow guide pipe 144, the sewage is guided to the hollow portion of the first water inlet pipe 11 along with the pipe wall of the flow guide pipe 144, so that the sewage is prevented from dropping on the communication position between the second water inlet pipe 12 and the first water inlet pipe 11. The structure of the flow guide tube 144 is not particularly limited, for example, the flow guide tube 144 may be an inverted circular truncated cone or an eccentric circular truncated cone, or may be a structure in which a circular tube is connected to an inverted circular truncated cone or an eccentric circular truncated cone, preferably, in this embodiment, the flow guide tube 144 has a top end that is a circular tube and a bottom end that is an inverted circular truncated cone, the diameter of the circular tube is the same as the diameter of the bottom end of the circular truncated cone, and the circular tube is coaxially connected to the circular truncated cone.
Since the temperature of the sewage/wastewater from the upper main drainage pipeline varies according to the source, the temperature of the sewage/wastewater varies, for example, the temperature of the wastewater generated by showering is higher than that of normal domestic water by about 30 ℃, and the temperature difference between the sewage/wastewater causes thermal expansion and contraction of the pipeline.
