Detailed Description
The invention relates to a novel indoor sewage discharge system, which comprises a vertical drainage pipe 1 penetrating a plurality of floors 3 and extending out of a roof 4 from the top end and a main drainage pipe 2 arranged on each floor 3, connected with the vertical drainage pipe 1 and used for collecting and conveying sewage on the floors into the vertical drainage pipe 1, wherein a first air suction valve 5 is arranged at the top end of the vertical drainage pipe 1, a second air suction valve 6 capable of leading indoor air to enter a pipeline is arranged on the main drainage pipe 2 on each floor 3, and a one-way valve 7 is arranged on the main drainage pipe 2 and close to the vertical drainage pipe 1.
The exhaust main pipe 2 of the uppermost end of the vertical drainage pipe 1 and each floor is provided with an air suction valve, the air suction valves can be arranged in a toilet, the air suction valves adopt breathing valves, for example, the PHXF-I type all-day air suction valve produced by Wuhan Pan Cin mechanical equipment Limited is used as the air suction valve of the system, through flange connection, the air suction valves can automatically introduce air in the atmosphere into the system under the condition of drainage in a pipeline, and the phenomenon that the toilet is counter-flavored due to water seal damage is completely avoided.
The check valve 7 between the drainage trunk pipe 2 and the drainage vertical pipe 1 on each layer only allows water flow in the drainage direction to pass through in a single direction, so that sewage in the pipe returns to the indoor of a low-rise household when the pipeline is blocked, gas in the pipe is also prevented from being discharged into the indoor due to pressure, and gas and mosquitoes in the drainage pipeline do not enter the indoor at each layer.
The drainage main pipe 2 is connected with a sewage generating unit of the floor where the drainage main pipe is positioned, the sewage generating unit can be a hand basin, a water pool, a defecation device and the like, a water seal is arranged at the joint of the sewage generating unit and the drainage main pipe 2,
