Abstract: The present invention relates to a freeze protection valve comprising a fluid flow pipe having an inlet on one side; a valve housing which is connected to the fluid flow pipe by the inlet and has an outlet discharging the fluid flowing inside; an elastic member which is included in a valve housing and changes elasticity due to temperature change of the fluid; and an opening and closing member opening or closing the outlet with the elastic member by being installed between the elastic member and the outlet. The freeze protection valve can prevent the fluid flow pipe from being frozen due to frozenness of the fluid by enabling the fluid of the fluid flow pipe to continuously flow.
