ある。2. Description of the Related Art Conventionally, as a measure for preventing freezing of a water pipe, there has been known a method in which water is constantly discharged from a water tap. This is because freezing can be prevented by keeping the water flowing even when the outside temperature falls below the freezing point, and since the water temperature in the water main is higher than the outside temperature, if the water in this main is always drawn in and allowed to flow into the pipe This is because there is no freezing inside the water pipe. However, keeping tap water flowing constantly is a waste of resources.

The figure shows the freeze protection method of the present invention. Bellows tube 1
Reference numeral 1 denotes a stretchable sealed tube in which a substance M having a boiling point slightly higher than the freezing temperature of water is sealed inside the pipe, and an introduction portion 17 for the sealed substance is formed at an end. The liquid sealed in the bellows tube 11 has a boiling point of 0.5 ° C to 4 ° C.
C. is preferable. Such liquids include Freon 114 (boiling point 3.6 ° C.), n-butane (boiling point 1
° C) and cyclobutane (boiling point 2 ° C). A valve member 12a that moves as the bellows pipe 11 contracts is fixed to the bellows pipe 11, and a valve 13 is formed integrally with a valve hole formed by attaching a member 12b to the end of the water pipe 15.

At this time, when the bellows tube 11 is expanded, the valve 13 is closed, and when the bellows tube 11 is contracted, the valve 13 is opened. Further, the water flowing out of the water pipe 15 is discharged to the outside through the discharge port 19. Also, an elastic member 14 such as a spring is arranged between both ends 20 and 21 of the bellows tube 11 so as to be extendable and contractible, so that the valve 1

１３の閉鎖状態を強固にし水漏れを防止する。When the ambient temperature around the bellows pipe, such as the outside air temperature or the water temperature in the water pipe, is sufficiently higher than the boiling point of the substance in the bellows pipe 11, the state of the substance is gas. When the environmental temperature approaches the freezing temperature of water, the gas in the bellows tube 11 condenses to a liquid, and the pressure inside the tube decreases, so that the bellows tube 11 contracts due to the atmospheric pressure. As a result, as shown in FIG. 1, the valve 13 is opened and the water in the water pipe flows out.
When the environmental temperature becomes higher than the boiling point of the substance in the bellows pipe 11, the liquid becomes gas again, and the bellows pipe 11 is extended and the valve 13 is closed as shown in FIG. At this time, the elastic member 14 presses the valve member 12a to strengthen the closed state of the valve 13, thereby preventing water leakage.

必要がなく、水道水が無駄に流される量を低減できる。According to the present invention, the water in the water pipe is drained immediately before the tap water freezes, and the outflow of the water stops when the temperature of the tap water becomes sufficiently higher than the freezing temperature. For this reason,
There is no need to constantly discharge tap water in order to prevent the water pipe from freezing, and the amount of tap water that is wasted can be reduced.
