Abstract
Description
technical field
[0001] The invention relates to a building water supply and drainage device, in particular to an anti-backflow pipe access device. Background technique
[0002] At present, there are many problems in the drainage system, such as leakage, back odor, noise, etc., especially the problems of leakage, pipe blockage, sewage overflowing into the room, and back odor pollution. In order to solve the above problems, many technicians have focused on the above problems Different solutions are proposed: 1. In the special single riser system, a hollow water flow is formed by setting a water channel at the junction of the horizontal pipe and the standpipe, so as to improve the ventilation capacity of the drainage standpipe and reduce the odor return of the floor drain; 2. Adopt Double standpipe method, set up a special ventilation pipe to reduce the problem of floor drain odor return; 3. Adopt double standpipe self-circulation mode to improve the exhaust capacity of the sta...
Examples
Embodiment 1
[0021] like figure 1 As shown, an anti-backflow pipeline access device includes a riser connecting pipe 4, a sewage drain pipe 9 with a water-sealed sewage discharge port 10, a waste water discharge pipe 7 with a waste water discharge port 8, and an air pressure regulating box 11 , the water-sealed box 1 and the water-sealed dividing hanging plate 6 arranged in the water-sealed box 1, wherein the top of the water-sealed and divided hanging plate 6 is hinged to the inner side of the top box wall of the water-sealed box 1, and the standpipe The connecting pipe 4 is set through the water-sealed box 1, and the standpipe connecting pipe 4 is provided with a drain port 5, and the lowest point of the drain port 5 is not lower than the bottom end of the water-sealed split hanging plate 6 so that The water seal box 1 forms a water seal; when the bottom end of the water seal partition hanging plate 6 is set on the wall of the water seal box 1, the water seal partition hanging plate 6 di...
Embodiment 2
[0028] The difference between this embodiment and Embodiment 1 is that one end of the sewage drainage pipe passes through the top wall of the water-sealed tank and communicates with the riser connecting pipe, so as to adapt to different drainage methods or structures.
Embodiment 3
[0030] The main difference between this embodiment and Embodiment 1 is that the sewage drainage pipe is arranged above the water-sealed box, that is, one end of the sewage drainage pipe is directly connected with the riser connecting pipe, so as to adapt to different drainage methods or drainage structure.
