とする弁座構造。 A valve chamber is formed by a valve casing, and a valve seat with an open valve opening is arranged to protrude to the side of the valve chamber, and the outer surface of a float freely accommodated in the valve chamber directly contacts the valve seat to open the valve. In a free-float type steam trap that opens and closes the mouth, the valve seat that opens the valve mouth is made of corrosion-resistant metal material such as stainless steel, and the outer periphery of the valve seat surface is provided with a A valve seat structure characterized by thermally spraying a self-fusing alloy material mixed with tungsten carbide to form a cemented carbide part, which is then remelted to form an alloy with an corrosion-resistant metal member and fixed to it.
