摘要: A valve device using pipe materials in which a fluid control mechanism is arranged and which comprises a valve device body (11) made of a metallic pipe material and having a tubular flange (21) integrally formed on the outer surface of the body so as to protrude therefrom, and a tubular member (12) for forming a flow passage, which is fitted and connected at the base end thereof to the top end of the tubular flange (21). The tubular flange (21) is formed so that the area of the opening at the base end thereof communicating with the flow passage within the valve device body is greater than the area of the opening at the top end of the tubular flange. The inner peripheral portion (21a) of the base end of the tubular flange (21) is formed with a smoothly curved surface, and the flow passage is formed along such a curved surface.
