Abstract:
1. A valve device capable of being used in a feeding apparatus for releasing raw material into raw material processing machinery for the manufacture of high-voltage cable, comprising: a valve body comprising a first valve member having a conical shape and comprising at least one opening extending between a tip of the first valve member and a corresponding base portion of the first valve member, and a second valve member comprising at least one cover element, one of said valve members being rotatable with respect to the other valve member between a first operating position in which the at least one cover element uncovers the at least one opening, thereby allowing the raw material to flow through the valve device, and a second operating position in which the at least one cover element covers the at least one opening, thereby preventing raw material from flowing through the valve device, wherein at least one wall of the first valve member not opened by the at least one opening defines a corresponding discharge sliding wall for conducting contaminants outside the valve body in the second operating position of the second valve member, wherein the valve body further comprises a valve body outer case laterally surrounding the first and second valve members, said valve body outer case comprising at least one discharging window coupled to the corresponding discharge sliding wall for discharging the contaminants from the discharge sliding wall outside the valve body of the valve device, and wherein the at least one cover element of the second valve member is a wedge-shaped element configured such as to cause, in the second operating position of the second valve member, contaminants falling thereon to slide toward the corresponding discharge sliding wall.
