Abstract

To provide a small and low-cost check valve (1, 1A, 100, 200) that enables to reduce a pressure loss and securely prevent backflow of a fluid. A check valve (1, 1A, 100, 200) includes a tubular body (3, 3A) forming a part of a flow path through which a fluid flows, a first housing (10) having a first valve hole (11) through which the fluid flows, with a valve seat (13) formed at a downstream side of an inner peripheral surface of the first valve hole (11), a valve body (20) having a flat part (20a) at a top thereof and including a valve head (21) and a supporting rod (22) connected to the valve head (21), the valve head (21) increasing in diameter in a tapered shape toward a downstream side thereof, a spring member (30) for biasing the valve body (20) toward the valve seat, and a second housing (40) having a connecting section and a cylindrical body, the connecting section including a second valve hole, the cylindrical body (42) being open to an upstream side thereof and including a receiving surface formed at a downstream side thereof for receiving one end of the spring member (30) and a sliding hole (42a) formed at a central part thereof through which the supporting rod (22) of the valve body slides. The cylindrical body (42) of the second housing (40) decreases in diameter in a tapered shape toward the downstream side thereof, and has notches (44) on an upper edge thereof opposing one surface at the downstream side of the valve head (21) of the valve body. The most suitable drawing: Fig. 2a and Fig. 2b
