。A valve box having an inlet, an outlet, and a check surface between them on the same axis, forming an inlet chamber between the inlet and the check surface, and a valve chamber between the check surface and the outlet; A valve body that is housed in the valve chamber and is fitted with a non-return gasket that tightly contacts the non-return surface, a spring that applies a pressing force to the valve body in the direction of the inflow port, and a spring that presses the valve body in the direction of the outflow port when draining water. This backflow prevention valve for cold regions consists of an operating rod, one side of which is exposed in a water inlet chamber and the other side exposed to the atmosphere, and is arranged obliquely from the upstream side with respect to the valve body.
