A nonfreezing valve for the water supply to prevent the air from contacting a water pipe directly is provided to prevent the water pipe from freezing and being broken by supplying the subterranean heat to the pipe. A nonfreezing valve for the water supply comprises a water pipe(3), an adiabatic material(4), a plastic protecting duct(5), a faucet(6), a cover(11), and a cap(12). A valve(2) having a deposit hole(H) is installed at the water pipe. The adiabatic material prevents the icing and frost break of the water pipe. The adiabatic material has a space in which the subterranean heat is supplied. The adiabatic material is buried between the protecting duct and the water pipe. The plastic protecting duct surrounds the adiabatic material. The faucet is screwed at the top of the water pipe. The top of the adiabatic material and the protecting duct are sealed with the stopper and cap hermetically. |
