Abstract

The invention discloses a composite material for a stop valve. The composite material comprises LaNbO4, Mo2FeB2-based metal ceramic, Nb2O5, Ti6Al4V, Ag-Al2O3 metal ceramic, NiFe2O4 and Cr3C2-NiCr. The composite material comprises, by weight, 15-25 parts of the LaNbO4, 20-40 parts of the Mo2FeB2-based metal ceramic, 12-24 parts of the Nb2O5, 16-26 parts of the Ti6Al4V, 45-60 parts of the Ag-Al2O3 metal ceramic, 18-28 parts of the NiFe2O4 and 33-48 parts of the Cr3C2-NiCr. In this way, the stop valve is high in fluid resistance bearing capacity and not prone to being damaged.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a composite material used for stop valves. Background technique [0002] The opening and closing part of the globe valve (stopvalve, GlobeValve) is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves linearly along the centerline of the valve seat. The movement form of the valve stem, (common name: dark rod), also has a lifting and rotating rod type, (common name: bright rod). The globe valve refers to the valve in which the closing part (disc) moves along the centerline of the valve seat. According to the movement form of the disc, the change of the port of the valve seat is proportional to the stroke of the disc. Because the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat opening is proportional to the stroke of the valve dis...
