[0032] See Figure 4 , In the second embodiment of the present invention, there is an inwardly inclined blocking piece 12 between the transverse branch pipe interface 3 and the air hole 51 . The blocking sheet 12 is shorter than the drainage sheet 11 . When the water flow entering from the transverse branch pipe interface 3 is too large, the water flow hits the drainage sheet 11 to cause splashing, while the blocking sheet 12 reduces the splashing range of the water flow, preventing part of the water flow from entering the ventilation pipe c through the ventilation hole 51. Compared with the first embodiment, this embodiment uses the blocking sheet 12 to block the splashing of the water flow, preventing the water flow from passing through the air hole 51 and entering the air pipe c.

[0033] See Figure 5 , Figure 6 , In the third embodiment of the present invention, the drain pipe 1 is provided with a connecting sleeve 7 extending downward and having a diameter smaller th...

Abstract

The invention relates to the field of drainage systems, in particular to a water-gas full separation drainage system. The water-gas full separation drainage system comprises a drainage pipe, a ventilation pipe and a water-gas separation assembly. The water-gas separation assembly is provided with a throat which extends downwards to the middle and shrinks, the throat communicates with the drainagepipe, the water-gas separation assembly is also provided with an air channel communicating with the ventilation pipe, and the air channel is higher than the throat. The throat with the diameter gradually reduced downwards is lower than the air channel and concentrates water flow, air enters a drainage pipe piece through the air channel and moves downwards along with the water flow, and then waterbackflow is avoided. Thus, the drainage system has the advantages of being simple in structure, preventing backflow, stabilizing air pressure, realizing unobstructed ventilation and realizing water-gas full separation.

Description

technical field [0001] The invention relates to the field of drainage systems, in particular to a drainage system for fully separating water and air. Background technique [0002] At present, there are three types of indoor drainage systems in buildings: the first is the drainage system below the ninth floor, which adopts the roof ventilating pipe for drainage, and there is no need to set up a special ventilation pipe; Special ventilation pipes, and require H-shaped pipes to be connected layer by layer or interlayer between the special ventilation pipes and the drainage standpipe. The sewage in the drainage vertical pipe vertically spirals along the pipe wall, and it is easy to form inertia at the H-shaped connection opening. The water curtain or water film blocks the connecting vent pipe opening, causing water to enter the H-shaped connecting pipe and enter the vent pipe, affecting the ventilation of the vent pipe, and the water curtain blocks the H-shaped connecting pipe n...
