Valve for blockage and odor-diffusion prevention of sewers
The invention discloses a valve for blockage and odor-diffusion prevention of sewers, which is arranged below a floor drain and installed in a sewer. The valve comprises a connecting seat, an upper cambered surface and a lower cambered surface, wherein the upper cambered surface and the lower cambered surface are respectively provided with a sunken arc surface, the valve is a tubular body, and the connecting seat is located at the top of the tubular body; the upper cambered surface is located on the inner wall of the tubular body, i.e. the upper cambered surface extends out of the inner wall to about the central line of the tubular body; the lower cambered surface is arranged on the inner wall, opposite to the upper cambered surface, of the tubular body, and the lower cambered surface extends out of the inner wall of the tubular body to about the central line of the tubular body and is located outside the tubular body so as to form a communicating port of the valve; the communicating port of the lower cambered surface is connected with a valve plate, and the external bottom surface of the valve plate is connected with the internal bottom surface of the lower cambered surface; and the position, at which the valve plate on the lower cambered surface is vertically located, is provided with a magnet. The valve belongs to a check valve implemented by using the action of gravity; and the valve is simple in structure, solid dirt is not easy to store, and the valve plate structure can effectively prevent odor-diffusion.
