The invention discloses a fluoroplastic full-lining
cutting ball valve, and relates to a special valve. The fluoroplastic full-lining
cutting ball valve comprises a valve body, a
valve seat, a valve cover, a valve rod and a valve ball. The valve body is provided with an inlet, an outlet and an upper end connecting opening, the inlet and outlet are separately connected with inlet and outlet flanges, the valve cover is fixed to the upper end connecting opening through a bolt and a nut, the valve rod passes through the valve cover to be fixed, and the valve rod is sealed with the valve cover through arranging
filling materials between the valve rod and the valve cover. The valve ball is arranged in the valve body, the valve rod and the valve ball are arranged integrally through
casting, and afluoroplastic layer is arranged on the inner side wall of the valve body in a full-lining mode. Fluoroplastic
layers are arranged on the inner and outer surfaces of the valve ball, and on the valve rod arranged in the valve body, and a fluoroplastic layer is arranged on the inner side surface of the valve cover. The valve rod and a ball body are processed by a
machine tool after being whole forged, the problems that the valve rod is prone to being applied with force and a ball body is broken after
welding the ball body and valve rod and a valve door cannot open due to the breaking of the valve rod and the ball body, and accidents are avoided; and the valve body and valve ball are fully lined with fluoroplastics, the fluoroplastic full-lining
cutting ball valve can run reliably under environment with strong acid and strong base and has high
corrosion resistance.
