Abstract:
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 used as a check valve when feeding slurry, comprising: a valve seat; a valve body for performing opening and closing operation by reciprocally moving in predetermined directions with respect to the valve seat; and a coil spring 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 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.

Claim (Index 4):
The cone valve according to  claim 1 , wherein entire length of the coil spring is at least shorter than stroke length of the valve body, when the entire length is equal to or less than free length.
