Description
Technical Field
The invention relates to the technical field of building indoor drainage systems, in particular to a novel double-vertical-pipe building indoor drainage system.
Background
At present, three forms of indoor drainage systems for buildings exist: firstly, drainage systems below nine layers adopt a top extending vent pipe for drainage, and a special vent pipe is not required to be arranged; secondly, the indoor drainage system of the bathroom is provided with a drainage vertical pipe and a special ventilation pipe, the special ventilation pipe is communicated with the drainage vertical pipe layer by layer or is communicated by an interlayer, sewage vertically spirally flows along the pipe wall in the drainage vertical pipe, an inertial water curtain or a water film is easily formed at an H-shaped communication opening to be blocked and connected with the ventilation pipe orifice, so that water enters the H-shaped connection pipe and enters the ventilation pipe to influence ventilation quantity of the ventilation pipe, the water curtain blocks the opening of the H-shaped connection pipe, gas in the ventilation pipe is blocked from entering the drainage vertical pipe to supplement gas and enter the ventilation pipe, further, the fluctuation of the gas pressure in the drainage vertical pipe is larger, the direct synchronous influence on the gas pressure in the drainage horizontal pipe is directly generated, odor in the vertical pipe breaks a water seal to enter a room, and the floor drain returns; in order to solve the communication effect of the H-type communication pipe and improve the gas exchange capability of the drain riser and the vent riser, many researchers have made efforts and researches.
Patent document CN203346963U discloses a cyclone double-riser drainage system, which adopts a structure that a stop piece is arranged in a communicating pipe and the communicating pipe is obliquely arranged to prevent water in the drainage riser from entering a ventilation riser along the communicating pipe, so that the problem of reducing ventilation capacity of the ventilation riser caused by water inlet of the ventilation riser is solved. ( The drainage system is characterized by comprising a first vertical pipe and a second vertical pipe which are arranged in parallel, wherein the first vertical pipe is used for drainage, the second vertical pipe is used for exhausting, the first vertical pipe and the second vertical pipe are mutually communicated through a communicating pipe, gas in the first vertical pipe flows into the second vertical pipe to be exhausted through the communicating pipe, the first vertical pipe is a reinforced internal spiral drainage pipe, a plurality of spiral ribs are arranged in the first vertical pipe, and the communicating pipe is obliquely upwards arranged from the first vertical pipe to the horizontal direction of the second vertical pipe so as to prevent water in the first vertical pipe from overflowing into the second vertical pipe. And a plurality of stop pieces facing the first vertical pipe are arranged inside the communicating pipe. )
Patent document CN107938769a discloses an H-pipe and a drainage system including the H-pipe: the two ends of the connecting pipe are respectively communicated with the drainage vertical pipe and the ventilation vertical pipe, a guide plate is arranged in the drainage vertical pipe, one end of the guide plate is connected with the inner wall of the drainage vertical pipe, the other end of the guide plate extends into the connecting pipe, and a gap is formed between the guide plate and the connecting pipe. The water in the drainage vertical pipe is guided by arranging the guide plate at the junction of the drainage vertical pipe and the connecting pipe and extending the guide plate into the connecting pipe, so that the problem that the wall-attached flow encounters the water curtain at the junction of the connecting pipe orifice to block and ventilate is solved, and meanwhile, the problem that the water enters the ventilating pipe through the connecting pipe is also solved, so that the ventilation capacity of the whole system is improved.
Patent document CN 205839888U discloses a backflow preventing H pipe for building drainage, which solves the technical problem that the existing H pipe for building drainage is easy to damage water seal in a drainage system and causes the odor returning phenomenon of a toilet. It comprises the following steps: drainage riser, aeration riser and aeration riser, wherein: a first baffle is vertically and downwards arranged at the joint of the upper wall of the ventilation inclined tube and the drainage vertical tube; a second baffle is arranged at the position from the connection part of the lower wall of the ventilation inclined tube and the ventilation vertical tube to the axis of the ventilation vertical tube; and the pipe wall at one side of the connecting port of the ventilation vertical pipe relative to the ventilation vertical pipe and the ventilation inclined pipe protrudes outwards to form a ventilation curve so as to ensure smooth ventilation. The utility model has the advantages of effectively preventing water in the drainage pipeline from entering the ventilation pipeline, fully playing the ventilation effect of the ventilation pipeline, reducing pressure fluctuation in the drainage system and improving the drainage capacity.
To sum up, in order to improve the drainage capacity of the drainage system of the indoor double vertical pipes of the building, the current solution is to improve the internal structure of the double vertical pipe H-shaped communicating pipe or improve the junction structure of the connecting pipe and the drainage vertical pipe at the same time, so as to solve the blocking effect of the water curtain in the drainage vertical pipe on the pipe orifice of the H connecting pipe, reduce the water flow rate of the water in the drainage vertical pipe entering the ventilation vertical pipe through the connecting pipe, improve the gas exchange balance capacity in the drainage vertical pipe, reduce the air pressure fluctuation in the drainage vertical pipe, and further reduce the influence on the air pressure fluctuation in the drainage transverse branch pipe. That is, the basic structure of the prior double-riser drainage system is that the drainage transverse branch pipe and the drainage riser of each layer are an integral system which is communicated in a sealing way, and the air pressure fluctuation in the riser is directly transmitted to the drainage transverse branch pipe. The ventilation vertical pipe is indirectly communicated with the drainage transverse branch pipe through the drainage vertical pipe and the H connecting pipe.
Also, to enhance the water seal deodorizing ability, it is common to add an appliance breather pipe or an annular breather pipe to the double riser system. One end of the appliance breather pipe is connected to the outlet end of the sanitary appliance trap, and the other end is connected to the main breather vertical pipe; the annular vent pipe is arranged on the drainage transverse pipe of the sanitary ware, and is led out from the two sanitary ware at the initial end to the main vent vertical pipe or the auxiliary vent vertical pipe. That is, either the appliance breather pipe or the annular breather pipe is directly connected to the breather riser and is not in communication with the drain riser. Thus, building water supply and drainage design specifications require: the utensil breather pipe and the annular breather pipe are connected with the breather riser pipe at a rising gradient of not less than 0.01 at not less than 0.15 m above the upper edge of the sanitary ware. The device aims to prevent the drainage pipe from being blocked, and then the drainage pipe enters the ventilation vertical pipe along the ventilation pipe or the annular ventilation pipe, so that the ventilation capacity of the ventilation vertical pipe is affected, and the drainage capacity and the air pressure fluctuation of the drainage vertical pipe are further affected.
The device breather pipe and the annular breather pipe provide a ventilation mode that the transverse branch pipe is directly communicated with the ventilation vertical pipe, and the aim that the outlet end of the water trap of the drainage transverse pipe or the sanitary ware is communicated with the breather pipe and then the atmosphere can be effectively achieved. However, the installation requirement is higher than the upper edge of the sanitary ware, so the technical scheme has good deodorization effect, but the space occupation is very difficult to realize in the residential toilet due to the open installation of the pipeline.
