The gas water heater uses a combustible gas as a fuel to heat the cold water flowing through the heat exchanger in a combustion manner, thereby realizing the purpose of rapidly preparing hot water. Compared with electric heating water heaters, gas water heaters do not have to wait, and they are used as they are. Therefore, the use is more convenient and quick, and it is not wasted due to incomplete use. At present, most household kitchens and bath water heaters use gas to heat the tap water. In the heating process, a thermostat is generally required to monitor the combustion process to prevent dangerous situations. When the gas water heater is insufficiently burned during the heating process or if other gases are mixed in the fuel gas, it is easy to cause an abnormality in the supply air pressure, thereby causing the burning flame to sway. If a flammable object is placed nearby, it may cause a fire hazard. By attaching the brass extension to the thermostat and mounting it near the combustion probe. When the water heater is abnormal due to abnormal combustion, the temperature of the nearby brass extension head will rise, the temperature will be transmitted to the temperature controller and the switch circuit will be turned off to cut off the power supply of the water heater. Finally, the water heater will stop burning and stop burning. Avoid the danger of fire. The Honeywell 2450CMG Series thermostat consists of a temperature-sensitive bimetal disc that is electrically isolated from the switch, which triggers a normally closed contact. The contact opens when the surface or ambient temperature rises to the operational capture point of the calibration disc. The circuit remains open above the indoor ambient temperature until the manual reset button is pressed. Due to the light weight of the wafer and the small size of the product, the response to temperature changes is extremely rapid. The product is economical and efficient, with a riveted structure for manual resetting.
