Abstract

PURPOSE: To prevent a freeze proofing valve used for a water boiler or the like from accidents caused by burst or the like by discharging automatically water from the water boiler and piping when the water has freezing temperature.
CONSTITUTION: An inlet 1a and outlet 1b for water in a freeze proofing valve communicate to each other through a nozzle 4a. On the other hand, an outer frame 6 and reversing resilient diaphragm 7 form a closed chamber in which is enclosed a temperature feeling substance like Freon changing drastically its volume at 0W5°C of temperature. A rubber valve 10 is pressed against an opening of a nozzle 4a through a connecting rod 9 by deflection of the reversing resilient diaphragm 7 in the room temperature to confine water from the inlet 1a with the nozzle 4a. When the atmospheric temperature is lower than 5°C, the reversing resilient diaphragm 7 reverses its deflection to produce a cavity between an adjusting screw 4 and a rubber valve 10 and discharge water for preventing the valve from accidents caused by burst or the like due to freezing.
