Abstract
PURPOSE: To enable prevention of the wear of a valve plate even in a corrosive atmospheric condition, by applying heat treatment to the valve palte for an automatic valve used in a reciprocating compressor to the specific shore hardness and processing nitridation treatment to the surface of said valve plate.
CONSTITUTION: A valve plate 5 shall be polished, after heat treatment to hardness in Shore hardness of HS35W47 and nitridation treatment to its surface. The relation between hardness and life of the valve plate in a corrosive atmospheric condition is as shown in the drawing. For instance, for low hardness the scattering of life of the valve plate is not present, but for high hardness the wide scattering is produced according to the kind and quantity of a corrosion factor in a corrosive atmosphere C, in comparison with the case of a clean atmosphere B. Life of the valve plate is about 3,000hr even if its hardness is lowered to HS40 in a corrosive atmosphere, but prolonged to about four times when the surface is softly nitrided.
