Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1 to 3, in the present embodiment, a ceramic valve stem of a ball valve includes a valve stem body 1 made of ceramic, a plurality of channels 11 extending from an upper end surface of the valve stem body 1 to a bottom of the valve stem body 1 along an axial direction of the valve stem body 1 are formed in the valve stem body 1, and a filler 2 capable of improving strength of the valve stem body 1 is filled in the channels 11.
Referring to fig. 1 to fig. 3, in the present embodiment, the filler 2 is preferably an aluminum-based alloy filler or a polymer organic filler. In this embodiment, when the aluminum-based alloy filler is selected as the filler 2, the aluminum-based alloy filler is preferably an aluminum magnesium alloy filler or an aluminum copper alloy filler, however, it should be understood by those skilled in the art that the aluminum-based alloy filler may be other aluminum magnesium alloy filler or aluminum copper alloy filler, as long as the strength of the valve stem body 1 can be enhanced. When the filler 2 is a polymer organic filler, preferably, the polymer organic filler may be a polyurethane filler, a polytetrafluoroethylene filler, or a polypropylene filler. However, it will be understood by those skilled in the art that the filler 2 may be other types of fillers as long as the strength of the valve stem body 1 is enhanced.
