发明名称 SAFETY DEVICE FOR WARM WATER DEVICE
摘要 <p>PURPOSE:To obtain safety by automatically opening a valve of a pressure vessel when any of temperature or pressure is raised to a predetermined value. CONSTITUTION:When a pressure in a pressure vessel 18 is 0.85kgf/cm<2> and a temperature is raised from a normal state of lower than 80 deg.C (set arbitrarily) to 80 deg.C or higher, oil 16 contained in a cylinder 11 of a temperature sensor 10 is expanded to lift a piston 15, and a valve 4 is lifted through a bias spring 14, a lifting pin mounting member 13 and a lifting pin 12. Then, the valve 4 and a valve seat 6 are opened therebetween, hot water in the vessel 18 is discharged, and city water is newly supplied into the vessel 18. As a result, a temperature in the vessel 18 is lowered to lower than 80 deg.C, and returned to the normal state as shown.</p>
