Description
Technical Field
The utility model relates to a building plumbing field, specifically speaking relates to a drainage riser of embedded breather pipe.
Background
At present, the conventional vertical drainage pipe is in a single common structure and is commonly used for discharging domestic sewage of buildings and roof rainwater. However, for domestic sewage pipes used in buildings, it is often necessary to provide a vent pipe in the vicinity thereof and extending out of the roof, the vent pipe being connected to the drain pipe at a suitable location on each floor by a diagonal connection pipe. Therefore, air in the drainage system is smooth, the pressure is stable, and water seals of various sanitary equipment are protected favorably.
However, the problem is that because the vent pipe is arranged next to the drainage vertical pipe, each drainage vertical pipe has one vent pipe, and as the number of building layers increases, there may be more than one vent pipe beside one drainage vertical pipe. Therefore, the number of the openings for the vertical pipes to pass through the floor slab is increased, the possibility of leakage of the root parts of the vertical pipes in a wading room is mainly increased, and the problem of the waterproof quality of the building is also caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses just in order to solve above-mentioned technical problem and the drainage riser of embedded breather pipe that designs.
The utility model provides a technical scheme that its technical problem adopted is:
a vertical drainage pipe with an embedded vent pipe comprises an outer pipe, an inner pipe, a communication port and an inclined cover plate; the inner diameter of the outer pipe is larger than the outer diameter of the inner pipe, the inner pipe is arranged in the outer pipe, a drainage channel is formed between the inner wall of the outer pipe and the outer wall of the inner pipe, and the inner channel of the inner pipe is an exhaust channel; the inner pipe wall is provided with a communication opening, and the communication opening is externally provided with a downward inclined cover plate, so that gas in the drainage channel can enter the inner pipe exhaust channel through the communication opening, and meanwhile, water flowing downwards in the drainage channel is prevented from entering the inner pipe exhaust channel through the communication opening.
The inner diameter of the outer pipe is more than 1.8 times larger than the outer diameter of the inner pipe.
According to the drainage vertical pipe embedded with the vent pipe, the inner pipe is arranged in the center of the inner part of the outer pipe, and an annular drainage channel is formed between the inner wall of the outer pipe and the outer wall of the inner pipe.
According to the drainage vertical pipe with the embedded vent pipe, the upper edge and the two side edges of the inclined cover plate are adhered to the outer wall of the inner pipe, and the lower edge of the inclined cover plate extends downwards to exceed the lower edge of the communication opening, so that water flowing downwards in the drainage channel cannot enter the inner pipe exhaust channel through the communication opening, and air flowing upwards can enter the inner pipe exhaust channel through the communication opening.
The vertical drainage pipe with the embedded vent pipe is vertically provided with communication ports and downward inclined cover plates corresponding to the communication ports at intervals.
The utility model discloses unite two into one drainage riser and breather pipe, form "pipe in pipe" mode of outer pipe sleeve inner tube, the outer tube pipe diameter is far greater than the inner tube pipe diameter, and the annular space that forms between outer tube and the inner tube is used for discharging sewage, and the inner tube is then used for ventilating. A communicating opening is formed in the pipe wall in each layer, and an inclined cover plate is arranged outside the communicating opening to prevent sewage from entering the inner pipe through the communicating opening. In the roof layer, only the inner pipe is led out of the roof to form the vent pipe.
The specific pipe diameter of the outer pipe and the pipe diameter of the inner pipe can be calculated by combining the mathematical principle with the number of floors of a building, so that the sectional area of a circular ring between the outer pipe and the inner pipe meets the requirement of a water supply and drainage standard.
The utility model is characterized in that:
first, can effectively reduce the quantity that the pipeline passes through the building floor entrance to a cave to reduce construction strength, reduce engineering cost.
Secondly, reduce the possibility that room floor seepage was waded into to the building, improve the waterproof quality of building.
The utility model has the advantages that: the utility model provides a drainage riser design science of embedded breather pipe, realizes simply, can effectively reduce the quantity that the pipeline passes through building floor entrance to a cave to reduce construction strength, reduce engineering cost, have extensive popularization and application prospect in the building field.
