範囲第１項に記載のチエツクバルブ。[Claims for Utility Model Registration] 1. A valve body is housed in a valve chamber of a valve body equipped with an inlet and an outlet, and between the valve body and the bottom surface of the valve chamber there is a closure that contacts the valve seat. In a check valve that includes a valve closing spring that biases and holds the valve body in a position and allows the valve body to move to the open position when the fluid pressure reaches a set pressure, the valve body and the bottom surface of the valve chamber are connected to each other. 1. A check valve characterized in that a shape memory alloy spring is interposed between the valve body and the valve body to change the opening setting pressure of the valve body by expanding and contracting due to temperature changes. 2. The shape memory alloy spring is expanded in the cold to increase the set pressure for opening the valve body, and contracted in the warm to reduce the set pressure, as set forth in claim 1 of the utility model registration claim. Check valve.
