Abstract
The invention discloses a double buoyancy ball overflow preventing floor drain. The floor drain comprises a floor drain frame, a floor drain cover, an aqueduct, an outer sleeve, a buoyancy ball coverand a buoyancy sealing head; a water outlet is formed in the bottom of the floor drain frame, the upper end of the aqueduct is fixed to the bottom face of the floor drain frame and communicated with the water outlet, the outer sleeve sleeves the aqueduct, the lower end of the outer sleeve is sealed, an overflow opening is formed in the middle of the outer sleeve, a gap between the portion, below the overflow opening, of the outer sleeve and the aqueduct forms a water seal cavity, the buoyancy sealing head is located in the water seal cavity and matched with an outlet formed in the lower end ofthe aqueduct, the buoyancy ball cover of an open-bottom structure is arranged above the water outlet and internally provided with a left buoyancy ball cavity and a right buoyancy ball cavity, the left buoyancy cavity and the right buoyancy cavity are internally provided with buoyancy balls, a gap between the buoyancy balls forms a siphon passage, water inlets are formed in the corresponding positions, located above the buoyancy balls, of the top face of the buoyancy ball cover, and the buoyancy balls are matched with the water inlets. The floor drain is novel and ingenious in structure, highin drain speed, good in sealing effect and capable of effectively preventing overflow.
