From the movable sealing odour-proof floor drain
Technical field:
The utility model belongs to and is used for the sewage effluent technical field, particularly a kind of odour-proof floor drain.
Background technology
The existing floor drain that is used for sewage effluent that generally uses, its deodorant function is mainly realized by connected blow-off line with U-shaped water sealing (sealing water) pipe, but this only to adopt single water seal structure to exist not enough, especially when other local bath of same underground blow-off line system is used, when bath will produce the jet phenomenon by the moment of blow-off line at a high speed, water in the U-shaped pipe is sucked away, perhaps for a long time need not, water in the U-shaped water sealing (sealing water) pipe is very easily evaporation also, making up and down, pipe is communicated with, still do not have sealing process, thereby make lack of water in the U-shaped water sealing (sealing water) pipe and lose the smelly effect of envelope, the foul smell in the blow-off line is discharged into indoor and contaminated air by floor drain.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, designs a kind of novelly from the movable sealing odour-proof floor drain, and this odour-proof floor drain can be sealed the upper port of U-shaped water sealing (sealing water) pipe automatically under anhydrous state.
The technical solution of the utility model is: a kind of from the movable sealing odour-proof floor drain, comprise floor drain grate, floor drain housing, it is characterized in that being equipped with in the floor drain housing disc buoyancy aid, at this buoyancy aid soffit concentric one guide pipe is installed, this guide pipe top has the grid that water stream channel is provided, the internal diameter of this guide pipe cooperates with the upper end external diameter of U-shaped water sealing (sealing water) pipe, and both can be slided relatively.
Described guide pipe upper end is embedded in the disc buoyancy aid, or is threaded.
Described disc buoyancy aid soffit center is shaped on hemispherical plug, the diameter of this plug less than the internal diameter of guide pipe greater than the upper port internal diameter of U-shaped water sealing (sealing water) pipe.
The utility model utilizes law of buoyancy, when effluent sewerage, at first is filled in the floor drain housing, and the disc buoyancy aid rises together with guide pipe, and buoyancy aid separates with the upper port of U-shaped water sealing (sealing water) pipe, and sewage flows into the U-shaped water sealing (sealing water) pipe from the grid on guide pipe top; When the sewage discharge finishes, drawdown in the floor drain housing, the disc buoyancy aid descends together with the guide pipe gravitate, hemispherical plug is sealed the upper port of U-shaped water sealing (sealing water) pipe automatically, the foul smell in the isolated effectively sewer, and also draining is convenient, simple in structure, cost is low, convenient maintenance.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the shape schematic diagram of disc buoyancy aid and guide pipe among Fig. 1.
Among the figure: 1. floor drain grate, 11, the grate road, 2, the floor drain housing, 3, the disc buoyancy aid, 31, hemispherical plug, 4. guide pipe, 41, the guide pipe grid, 5, the U-shaped water sealing (sealing water) pipe.
The specific embodiment
In conjunction with the embodiments accompanying drawing is described in detail more below.
With reference to Fig. 1, Fig. 2, a kind of from the movable sealing odour-proof floor drain, comprise disc floor drain grate 1, reverse frustoconic floor drain housing 2, grate road 11 is formed on the floor drain grate, and sewage can be flowed in the floor drain housing.Disc buoyancy aid 3 is housed in the floor drain housing 2.In order to prevent that buoyancy aid 3 from floating the upper port from U-shaped water sealing (sealing water) pipe 5, buoyancy aid 3 soffits have the concentric annular groove, embed installation one guide pipe 4 by adhesive bonds, this plastics guide pipe top has the grid 41 that multiple tracks provides water stream channel, and the sewage in the floor drain housing flows into U-shaped water sealing (sealing water) pipe 5 by grid 41 and discharges.The internal diameter of guide pipe 4 cooperates with the upper end external diameter of U-shaped water sealing (sealing water) pipe 5, can slide relatively after making both sockets.Above-mentioned guide pipe 4 also can be threaded with disc buoyancy aid 3, but the screwed hole of opening at disc buoyancy aid 3 must be a blind hole.Be shaped on hemispherical plug 31 at the soffit center of disc buoyancy aid 3, the diameter of this plug less than the internal diameter of guide pipe 4 greater than the upper port internal diameter of U-shaped water sealing (sealing water) pipe 5, make it after draining finishes, to utilize self gravitation effectively to block outfall, thereby the foul smell in the sealing sewer overflows into indoor from outfall.
This when the draining in use of movable sealing odour-proof floor drain disc buoyancy aid 3 and guide pipe 4 thereof under the buoyancy of water effect, float and leave outfall, sewage is drained swimmingly by grid 41, draining finish and the floor drain housing in when anhydrous disc buoyancy aid 3 and 4 of guide pipes thereof under the self gravitation effect, block outfall automatically, completely cut off in the sewer and moved on the foul smell, avoided it room air pollution.
