摘要： PROBLEM TO BE SOLVED: To use functions of a boiling prevention valve, a relief valve, and a vacuum break valve at the same time by providing a valve element in a valve port communicating a primary side and a secondary side channel provided in the circumference of a pressure receiver part in the center of a diaphragm partitioning a valve casing into the primary side and the secondary side channel and penetratingly supporting a heat sensitive element pressurizing a receiver part in the valve element. SOLUTION: Where the pressure in a water heater is raised to a set pressure or more, a valve element 24 is displaced toward a secondary side channel 8 side along with a diaphragm 9 by the pressure increase in a primary side channel 7 so that even if the valve element 24 reaches a moving limit position, the diaphragm 9 is further displaced to open the valve element 24, release the pressure liquid in the primary side channel 7, and lower it to a set value. Where the water heater is evacuated by the temperature lowering, the pressure in the primary side channel 7 is lowered than the atmospheric pressure in the secondary side channel 8 so that the atmospheric pressure is sucked into the primary channel 7 to raise it to the set value. Where the temperature is raised, wax in the heat sensitive body 25 is expanded to thrust a piston 25, pressurize the pressure receiver part 16, and open the valve element 24 so as to lower the temperature in the primary side channel 7.
