Abstract

PURPOSE: To obtain a valve apparatus having superior wear resistance and chemical resistance by forming a runner, stuffing box, and a plug from ceramic material, in a valve apparatus which controls special fluid such as slurry and chemicals.
CONSTITUTION: On the inner surface 4 of a valve body 2, a cylindrical runner 5 made of ceramics is fixed with adhesive 6. On the central upper surface of the outer peripheral surface of the runner 5, a circular concaved part 7 is formed, and corresponding to this concaved part 7, a pentrating hole 8 having the same diameter is formed on the central upper surface of the valve body 2. Into the penetrating hole 8, a stuffing box 9 consisting of a based cylindrical body formed of ceramics is inserted, and the lower end part is inserted into the concaved part 7 of the runner 5 through a packing 10 made of Teflon etc. Onto the lower end of the valve shaft 11 which is moved up and down, the upper end of a cylindrical plug 13 formed of ceramics is inserted, and fixed firmly with adhesive 14.
