Air suction type floor drain drainage structure

Technical Field

The utility model relates to a drainage technical field, concretely relates to formula of breathing in floor drain drainage structures.

Background

The energy conversion of water flow in sewage and wastewater pipes and the pressure change in the pipes are severe, and many building sewage and wastewater pipes cannot extend out of a roof to be subjected to top-extending ventilation due to building reasons, for example, only one layer at the bottom is used for drainage, and other layers at the upper part are not used for drainage, so that the top-extending ventilation cannot be set. This will cause the problems of back-overflow of odor and unsmooth drainage of sewage and waste water. The odor overflows back to cause toxic and harmful gas to enter a room, so that the human health is directly harmed, the indoor environmental sanitation is influenced, and the accident hazard is high. Designers often use an increased drain pipe diameter to address these problems, but the design cost increases.

For realizing the purpose of the utility model, the utility model adopts the following technical scheme:

a suction-type floor drain drainage structure comprises: the suction type floor drain structure comprises a suction pipe, a trap and a drainage branch pipe; the air suction type floor drain structure comprises a top cover, a top plate, a chute, an air suction valve, a square tube and a bottom plate; the top cover is provided with a filtering hole, an opening is arranged on the top plate, and the top cover covers the opening; a chute and a square barrel are arranged below the top plate, and a lower notch of the chute is connected with the upper end of the square barrel; the square cylinder is positioned right below the opening on the top plate; the bottom of the chute is provided with an air suction valve, and the air suction valve and the opening on the top plate are mutually staggered in the vertical direction; the bottom of the square tube is provided with a bottom plate with a connecting port, a trap is arranged on the connecting port, and the lower end of the trap is communicated with a drainage branch pipe; the rear end of the air suction valve is connected with an air suction pipe, and the lower end of the air suction pipe is communicated with a drainage branch pipe.

Preferably, the opening of the top plate is provided with an inner eave, the top cover is lapped on the inner eave, and the top cover is flush with the top surface of the top plate.

Preferably, an inner lining is arranged at the bottom of the top plate at the opening position of the top plate, and a gap exists between the inner lining and the square tube.

Compared with the prior art, the utility model, following beneficial effect has:

1) the structure can adjust the air in the pipeline, when low pressure occurs in the pipeline, the air is put in, so that water flow in the sewage and wastewater drainage pipe is kept in a water film flow state, and odor is prevented from overflowing when high pressure occurs in the pipeline.

2) The structure replaces an outdoor ventilation cap through the suction valve, so that the building cost is saved, the smoothness of water supply and drainage of the building can be guaranteed, and the building is neat and attractive.

3) This structure is effectual has guaranteed trap water seal effect, promotes drainage system performance, has reduced because the unstable drainage noise that leads to of intraductal pressure.
