Maintenance-free wear-resistant ceramic ball valve

Abstract

The invention relates to the technical field of ceramic ball valves, and particularly discloses a maintenance-free wear-resistant ceramic ball valve, the side surface of a valve body is fixedly connected with a control part, the inner side of the valve body is rotatably connected with an opening and closing part, and the side surface of the control part is fixedly connected with the inner side of the opening and closing part. The maintenance-free wear-resistant ceramic ball valve is provided with the lubricating mechanism, after a proper amount of lubricating oil is injected into the oil storage tank through the one-way valve, when the handle is rotated to drive the valve rod to rotate, the valve rod synchronously rotates on the inner side of the connecting sleeve, and the side face of the valve rod interacts with the extrusion assembly to generate extrusion action; the extrusion promotes lubricating oil in the oil storage tank to flow into the liquid storage box through the piston cylinder, and then the lubricating oil is continuously conveyed to the sponge block through the connecting pipe, so that when the valve rod rotates in the connecting sleeve and makes full contact with the sponge block, the lubricating oil adsorbed by the sponge block can be evenly smeared on the side face of the valve rod, and effective lubrication on the valve rod is achieved. And the frequency of daily lubrication maintenance of the valve rod is reduced.
