摘要：A wear-resistant valve assembly includes a valve body; a stem penetratingthrough the valve body; a valve disk installed in the chamber of the valve body andcontacting an inner wall of the valve body; a valve body wear-resistant layer formed at aninner annular area of the valve body, which is also at a position contacting the valve disk;
and a valve disk wear-resistant layer formed on an outer annular area of the valve disk ata position contacting the valve body; and wherein the valve body wear-resistant layer andthe valve disk wear-resistant layer are made of materials selected from carbon alloys andsatellite alloys. Furthermore, the valve disk is a triple-eccentric structure; and a drain-proof-ring wear-resistant layer and a valve seat wear-resistant layer are further formed.
