防止弁。The valve body has an inlet and an outlet on the same axis, a drain on the side of the middle part, and a check surface adjacent to the inlet, and a valve body that comes into close contact with and separates from the check surface. The valve body is connected by a supporting arm between the check part to which the check packing is attached, the guide part provided on the downstream side of the check part, and the spring locking part adjacent to the guide part, and the valve element is constantly pressed in the direction of the inlet by the spring. Then, the valve body is moved by pressing the spring locking part from the side, and the inflow port and the outflow port are connected to each other, and in order to open both to the atmosphere, the valve body is moved to the drain port and then to the gap between the support arms. A backflow prevention valve for use in cold regions, comprising a pressing part whose tip protrudes, and a drain valve having a water stop part having a communication hole therein on the downstream side thereof.
