In this embodiment, the turbulence part 31 is a plurality of inclined ribs provided on the inner wall surface of the lower riser 3, and the inclined ribs guide the sewage to be discharged downward in a clockwise or counterclockwise rotation.
Please describe the process of sewage discharge and air pressure balancing with reference to fig. 2 and 7: the central axes of the upper riser 1, the inner pipe section 21 of the header 200 and the lower riser 3 coincide, as indicated by central axis A-A in fig. 7. The sewage received by the upper vertical pipe 1 enters the turbulent part 31 of the lower vertical pipe 3 from top to bottom through the sewage channel 101, the turbulent part 31 guides the water flow to rotate and flow downwards, so that the air or the downward compressed air which is wrapped in the water flow which falls rapidly in the upper vertical pipe 1 is released, enters the air pressure balance cavity 203 through the lower vent hole 204, is communicated upwards to the sewage channel 101 at the upper section through the upper vent hole 204 of the air pressure balance cavity 203, and realizes the pressure difference balance at different positions above and below the sewage channel 101; the sewage received by the branch pipe interface 51 enters the position of the turbulence part 31 of the lower vertical pipe 3 through the water outlet 230 and the lower vent 204 of the collecting cavity 202, the turbulence part 31 guides the water flow to rotate and flow downwards, so that the air or the downward compressed air which is clamped in the water flow which falls rapidly in the collecting cavity 202 is released, the sewage enters the air pressure balancing cavity 203 through the lower vent 204, and is communicated upwards to the sewage channel 101 at the upper section through the upper vent 204 of the air pressure balancing cavity 203, so that the air pressure in the upper section and the lower section of the sewage channel 101 and the air pressure in the collecting cavity 202 are communicated and balanced through the water outlet 230, the lower vent 204 and the upper vent 210 which are communicated with each other, and the phenomenon that the sewage in the sewage channel 101 rushes into the collecting cavity 202 to be backflushed into a user chamber due to air pressure difference is avoided, and the water seal liquid in the collecting cavity 202 is sucked out to cause the water seal function failure.
As can be seen from the above description of the specific embodiments, the assembled same-layer drainage collector provided by the invention is assembled by a plurality of split pipe fittings, and a relatively complex structure can be formed in the collector, so that the collector is beneficial to integrating multiple functions, is convenient to produce and manufacture, and can improve the manufacturing yield; a collecting cavity 202 is formed in the collector, a water seal cavity is formed in the collecting cavity 202, so that odor in the sewer pipe can be prevented from overflowing into the room through the collecting cavity 202; the collector is provided with an air pressure balancing cavity 203, and the air pressure balancing cavity 203 is used for balancing the pressure difference between the upper section and the lower section of the sewage channel 101 and the collecting cavity 202, so that the sewage in the sewage channel 101 rushes into the collecting cavity 202 to cause the sewage to recoil into a user room due to the air pressure difference, and the water sealing liquid in the collecting cavity 202 is sucked out to cause the water sealing function to be invalid.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
