置用逆止弁。 A cover body having an air outlet is connected to a body having an air inlet, and a cylindrical valve body is fitted inside the body to separate the inlet and the outlet. A valve hole is drilled in the circumferential surface of the valve hole to communicate the above-mentioned inlet and outlet, and when compressed air flows in from the inlet, the area around the valve hole expands due to the pressure. A check valve for a powder transport device, characterized in that an O-ring is fitted so as to open the valve hole when the compressed air flows in, and to contract and close the valve hole when the inflow of the compressed air is stopped.
