Description

Technical Field

[0001] The utility model relates to the technical field of weight-reducing drainage, in particular to a building drainage double water seal system assembly. Background Art

[0002] According to building drainage requirements, each drainage point is equipped with odor-control devices such as traps. During drainage pipe construction, traps are often installed at the ends of horizontal branch pipes or at sanitary fixtures. After the horizontal branch pipes on each floor converge, a trap is installed on the horizontal main drainage pipe. This creates a "double water seal" problem. This "double water seal" problem can cause air blockage, resulting in air stagnation and poor drainage.

[0003] To avoid air blockage, any of the traps in the double water seal can be eliminated. However, if a trap is only installed at the end of the horizontal branch pipe or under the sanitary ware, the water seal in the trap will evaporate and become ineffective if there is no drainage for a long time, and toxic and harmful gases in the pipe will enter the room, which cannot guarantee the sanitation and safety of the indoor environment. If a trap is only installed in the horizontal drainage main pipe, it can only ensure that the toxic and harmful gases in the vertical drainage pipe do not enter the room, but cannot ensure that the drainage points are isolated from each other. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a double water seal system assembly for building drainage, which no longer causes poor drainage due to air blockage, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model is realized through the following technical solutions: a building drainage double water seal system assembly, including a drainage riser and a ventilation pipe, the ventilation pipe is arranged on one side of the drainage riser, a single or multiple sewage drainage pipes and wastewater drainage pipes are installed on the drainage riser, a wastewater horizontal main pipe is installed on the wastewater drainage pipe, a horizontal main pipe water trap is provided on the wastewater horizontal main pipe, a single or multiple wastewater horizontal branch pipes are installed on the wastewater horizontal bar pipe, a horizontal branch pipe water trap is provided on the wastewater horizontal branch pipe, and the ventilation pipe is connected to the single or multiple wastewater horizontal main pipes.

[0006] As an optimal technical solution, a connecting pipe is installed on a section of the ventilation pipe close to the wastewater horizontal main pipe, the other end of the connecting pipe is installed at the front end of the water trap of the horizontal main pipe, and the end of the connecting pipe connected to the wastewater horizontal main pipe is arranged between the water trap of the horizontal main pipe and the water trap of the horizontal branch pipe.

[0007] As a preferred technical solution, one end of the ventilation pipe is extended to the outdoors.

[0008] As a preferred technical solution, the horizontal branch pipe water traps are respectively P-type water traps, S-type water traps and universal water traps, and the horizontal branch pipe water traps are used to connect the sanitary ware drainage.

[0009] As a preferred technical solution, the ventilation pipe is arranged in parallel with the drainage riser.

[0010] The beneficial effects of using the new type are:

[0011] 1. This system has a wide range of applications. Whether a trap is installed at the end of a wastewater branch pipe or under a sanitary ware, as long as there is a double water seal, it can effectively ventilate and eliminate air blockage.

[0012] 2. Only the head end needs to be connected to the front end of the water trap of the horizontal main pipe, and the end can be connected to the outdoors in a variety of ways. It can guide the air, effectively discharge toxic gases, and ensure the hygiene and safety of the indoor environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 and Figure 2 As shown, the utility model is a building drainage double water seal system assembly, including a drainage riser 4 and a ventilation pipe 3, the ventilation pipe 3 is arranged on one side of the drainage riser 4, and multiple sewage drainage pipes 9 and wastewater drainage pipes are installed on the drainage riser 4, and wastewater drainage pipes are installed with wastewater horizontal main pipes 8, and wastewater horizontal main pipes 8 are provided with horizontal main pipe water traps 5, and multiple wastewater horizontal branch pipes 7 are installed on the wastewater horizontal bar pipe, and the wastewater horizontal branch pipes 7 are provided with horizontal branch pipe water traps 6, and the ventilation pipe 3 is connected to the multiple wastewater horizontal main pipes 8.

[0021] In this embodiment, a connecting pipe 10 is installed on a section of the ventilation pipe 3 close to the wastewater horizontal main pipe 8, and the other end of the connecting pipe 10 is installed at the front end of the horizontal main pipe water trap 5, and one end of the connecting pipe 10 connected to the wastewater horizontal main pipe 8 is arranged between the horizontal main pipe water trap 5 and the horizontal branch pipe water trap 6. As long as there is a double water seal phenomenon, effective ventilation can be achieved to prevent air blockage.

[0022] In this embodiment, one end of the ventilation pipe 3 is extended to the outside, so that the poisonous gas in the ventilation pipe can be discharged to the outside, avoiding affecting the indoor environment.

[0023] In this embodiment, the horizontal branch pipe water traps are respectively a P-type water trap, an S-type water trap 2 and a universal water trap 1, and the horizontal branch pipe water trap 6 is used to connect the sanitary ware drainage.

[0024] In this embodiment, the ventilation pipe 3 and the drainage riser 4 are arranged in parallel, so that the ventilation pipe and the drainage riser can be vertically arranged in the pipeline shaft, which facilitates the arrangement of the pipelines.

[0025] Set up a ventilation pipe, which is connected to the front end of the water trap of the horizontal main pipe, and the other end is connected to the outdoor ventilation. When the pipe is draining normally, the gas in the pipe can be discharged to the outside through the ventilation pipe between the water trap of the horizontal branch pipe and the water trap of the horizontal main pipe, avoiding the air blockage phenomenon, so that the toxic gas inside the pipe can be discharged smoothly, avoiding affecting the indoor environment;

[0026] During the construction of drainage pipes, no matter what form of water trap is used, as long as there is a double water seal, the problem of poor drainage caused by air blockage can be solved by adding a ventilation pipe between the two water traps.

[0027] A ventilation pipe is added to the pipeline well. The ventilation pipe is installed between the water trap of the horizontal main pipe and the water trap of the horizontal branch pipe through a connecting pipe, and then connected to the outdoor ventilation to solve the problem of poor drainage of the double water seal.
