いることを特徴とする逆止弁。 A connecting cylindrical body disposed between the flanges of opposing pipe materials; and a connecting cylinder disposed within this cylindrical body, which is provided with a connecting cylinder disposed between flanges of opposing pipe materials; When the valve is expanded and the pressure from the fluid disappears during the forward flow, it deforms into a flat shape due to the elasticity of the material, and the inner surfaces of the opposing ends are in close contact with each other in a watertight manner. A space is provided on the inner surface of the cylindrical body to accommodate an extending portion that extends radially outward when the valve body is in the flattened state compared to when the valve body is in the expanded state. A check valve characterized by:
