防止装置。 A valve seat case is connected and fixed to the water supply pipe via a branch pipe, and one end of the valve body, which is slidably inserted into the valve seat case, protrudes into the branch pipe, and the valve body is activated by the water pressure inside the water supply pipe. While the valve body is brought into contact with the inner end surface of the seat case so as to be able to move toward and away from the seat case, a drainage passage is formed inside the valve body to control the communication of the inside of the water supply pipe to the outside by the opening and closing operation of the valve body, and the valve body is closed by volumetric expansion. A freezing prevention device characterized in that a freezing chamber for opening the valve body is formed between the inner circumferential surface of the valve seat case and the outer circumferential surface of the valve body.
