Problems solved by technology

But at present, it is found that there are still some points that need to be further improved. For example, after the water discharged from the superstructure falls vertically to the current floor along the public riser, although there is a water flow center line in the middle of the water flow channel that is biased towards the inlet. , the bias flow channel on the side of the central axis of the water outlet, but if the flow rate of its drop cannot be effectively reduced or the pressure of its water flow is relieved, the flow rate of the vertically falling water flow in the standpipe will increase to a limit value and may be formed instantly in the public standpipe. The sealing of the cross section causes the gas in the public standpipe to generate a large positive or negative pressure, and the large positive pressure may affect the stability of the common water seal liquid level
Another example is that the horizontally flowing discharge water in the shared water-sealed chamber with multiple waste water horizontal branch pipe interfaces and the vertically descending water flow in the standpipe tend to collide and produce water tongue phenomenon, especially when the standpipe is vertical. When the falling water flow is at the peak flow rate, the sewage in the standpipe may flow back and overflow into the common water seal and sewage lateral branch pipe
In addition, the same-floor drainage concentrator of the building’s zero-drop slab and its common water seal are usually installed in the pipeline well, and the openings for inspection / maintenance and cleaning of the common water seal on it are mostly located in the pipeline well and are flush with the surface finish on the ground Or roughly flush position, and the height of the inspection door on the wall of the pipe well from the ground is often beyond the arm length of a normal person (such as when the opening of the inspection door is arranged above the bathtub), which also leads to the inconvenience of cleaning and dredging and difficulties

Embodiment Construction

[0016] Figure 1 to Figure 5The improved same-floor drainage concentrator for building zero-falling slabs shown in the present invention is a further improvement and improvement on the basis of basically maintaining the same-floor drainage device for building zero-falling slabs of CN110725369A, including: Between the water inlet port 1 of the standpipe and the water outlet port 5 of the standpipe at both ends, there is a standpipe offset of a non-circular through water flow channel with a water flow centerline 20 that deviates from the pipe centerline 6 and has a cross-section of unequal diameter. Chamber section 2, at the pipe wall where the long diameter of the non-circular cross-section water flow channel of standpipe offset chamber section 2 is located, is provided with a sewage horizontal branch pipe interface 10 for connecting with the sewage pipe of toilet toilet; The pipe offset chamber section 2 is provided side by side with a shared water-sealed chamber 8 that is ind...

Abstract

The invention discloses an improved building zero reducing plate same-floor drainage collector. A vertical pipe deviation cavity section with a water flow center line deviating from a pipeline centerline is arranged between a vertical pipe water inlet connecting pipe opening and a vertical pipe water outlet connecting pipe opening arranged at the two ends of the pipeline center line, wherein thevertical pipe deviation cavity section communicates with a water flow channel. The vertical pipe deviation cavity section is provided with a sewage transverse branch pipe connecting opening used for being connected with a sewage draining pipeline. A common water seal cavity which is independent and is provided with at least one waste water transverse branch pipe connecting opening used for being connected with a waste water discharging pipeline is arranged by being parallel to the vertical pipe deviation cavity section. A water flow outlet of the common water seal cavity and a water flow outlet of the vertical pipe deviation pipe section are converged below the pipeline and are connected to the vertical pipe water outlet connecting pipe opening along a pipeline lower section with a water flow center line being consistent with the pipeline center line. The vertical water inlet connecting pipe opening and the vertical pipe deviation cavity section are in smooth transition connection through a bend section with the smooth curvature. An inlet section center line and an outlet section center line of the bend section are consistent with the center line of the water inlet connecting pipeopening and the water flow center line of the vertical pipe deviation cavity section correspondingly, and the sectional area of an outlet is larger than the sectional area of an inlet. By means of thestructure, the structure and effect of the building zero reducing plate same-floor drainage collector are optimized and completed, water flow falling in the vertical pipe can be more smooth while thewater falling height is reduced, air pressure fluctuation in the vertical pipe is reduced, and it is ensured that a water seal is not damaged.

Description

technical field [0001] The invention relates to a zero-drop board same-floor drainage device for buildings, especially used for zero-drop board same-floor drainage in sewage / wastewater discharge pipes of various buildings such as toilets and balconies in building constructions including residences and offices aggregator. Background technique [0002] In order to solve the long-term use of the overall or partial lowering of the drainage system in the bathroom of the building, the publication number CN104975645A; CN104727430A and other Chinese patent documents have respectively proposed some constructions. or defects. In response to these problems, the Chinese patent literature with the publication number CN110725369A has reported a new structural form of the same-layer drainage device for zero-drop panels in buildings. Between the openings, there is a standpipe offset chamber section where the centerline of the water flow through the water flow channel deviates from the cen...
