20120112870 | THERMAL PROTECTION DEVICE AND METHOD - A solenoid valve for use in a hazardous environment requiring a surface temperature of the valve to not exceed a cutoff temperature, the valve comprising coil configured to physically move an armature using an field generated by the coil; a thermal cutoff device having a fusing temperature above the cutoff temperature; and a heating resistor sized and configured to raise thermal cutoff device's temperature to the fusing temperature before the surface temperature exceeds the cutoff temperature. A method of constructing a solenoid valve for use in a hazardous environment requiring a surface temperature of the valve to not exceed a cutoff temperature, the method comprising the steps of: selecting a thermal cutoff device having a fusing temperature above the cutoff temperature; and selecting and configuring a heating resistor to raise thermal cutoff device's temperature to the fusing temperature before the surface temperature exceeds the cutoff temperature. | 05-10-2012 |
20120299689 | SAFETY CONTROL STRUCTURE FOR HEATER WIRE - A safety control structure for heater wire comprises a switch, a first heating wire, a second heating wire, and an over-current protection element, which are sequentially connected in series connection. An insulation and fusible layer is interposed between the first heating wire and the second heating wire. Accordingly, under normal condition, the switch is triggered by triggering the circuit, so as to have the first heating wire and the second heating wire then be heated up within a preset temperature range. When the first heating wire and the second heating wire produce exceptionally high temperatures to fuse the insulation and fusible layer, the current is increased instantaneously because the first heating wire and the second heating wire are short-circuited. Therefore, the circuit is interrupted by the over-current protection element to show a broken circuit status in order to stop heating up. | 11-29-2012 |
