摘要： A temperature sensitive valve includes a body having an interior area, a top end having an inlet and a lower end having an outlet. The top end is design and configured to be removably secured to an exterior faucet located for allowing water to flow when the temperatures are approaching extreme cold conditions, such as freezing, so as to prevent the pipes from freezing, and eventually bursting. Located within the body, between the inlet and outlet, is a resilient tube situated in a bent position. Affixed to the resilient tube an elongated rod fabricated from a temperature sensitive material. As temperatures approach freezing conditions, the rod will decrease in size and thus move away from the resilient tube, enabling it to move upward and thus, become slightly unbent. This will provide for an opening to exist within the bent region of the tube and enable fluid flow. As temperatures increase and move away from freezing conditions, the rod increases in size, and thus forces the tube downward in a completely bent position, causing a blockage within the bent region. This will prevent fluid flow.
