を特徴とする凍結防止装置。 Fix the cylinder to the water pipe via a branch pipe,
A valve body is slidably inserted into the cylinder, while
A valve seat is fixed in the branch pipe, and a return spring is provided to cause one end of the valve body to protrude into the branch pipe and come into contact with the valve seat, and one end is closed by the valve seat and the other end is closed to the outside. A drainage passageway is formed inside the valve body, and a freezing chamber is formed between the inner circumferential surface of the cylinder and the outer circumferential surface of the valve body to open the valve body by the volume expansion effect when water turns into ice. An anti-freezing device characterized by the following:
