| description | A purpose of the present invention is to provide a cone valve, which significantly reduces a risk of damaging a valve seat, even if it is used as a check valve when feeding slurry containing highly abrasive coarse particles such as slurry of nickel oxide ore. The cone valve of the present invention is a cone valve (1) used as a check valve when feeding slurry, comprising: a valve seat (13); a valve body (11) for performing opening and closing operation by reciprocally moving in predetermined directions with respect to the valve seat; and a coil spring (14) incorporated to make the valve body contact the valve seat, wherein an annular abutting surface is provided in the valve seat by a contact with an end (1 1a) of the valve body, and the valve seat is configured to have a thickened part in which a thickness in normal direction of the abutting surface is increased inward from the abutting surface. |
