止弁の解放装置。A check valve is provided with a check valve body that is energized by a spring and prevents backflow from the outlet side in the middle of a main passage to a faucet outlet, the valve body having pressure on the side in the direction of movement of the valve body. An action chamber is provided, and a piston is disposed inside the pressure action chamber so as to move in the same direction as the valve body movement direction, and one rod portion of the piston is moved toward the valve body side, and the other rod portion is moved toward the valve body side. Furthermore, the one rod portion and the valve body are such that when the piston moves toward the one rod portion, the valve body can move in the valve opening direction independently of the piston; When moved to the other rod side, the valve bodies are engaged with each other so as to be forcibly pulled one time in a direction away from the valve seat, and there is a gap between the other rod portion side of the pressure action chamber and the main passage. A release device for a check valve for a water faucet, characterized in that a communication path is provided to communicate with each other.
