ABSTRACT:
Water cock has non-freezing valve. Though temperature of the water flowing through the cock is lowered below the freezing point owing to the severe surrounding condition in the winter, the improved cock having a non-freezing valve does not stop its flowing of water. The cock has a thermo-element sensing the surrounding temperature and driving the non-freezing valve to shut and open according to the temperature. The thermo-element consists of a base portion containing heat-sensitive-material and a cylinder containing jelly-like material for transferring the expanding force of the heat-sensitive material to a shaft buried in the jelly-like material.
