The identification of the cause of the elevator accident can be analyzed from the following aspects:
1, damaged thermostat
Water heater length Time use causes more scale in the water heater, and the thermostat is easily damaged over time. Once the water heater thermostat is damaged, it means that the water heater cannot automatically control the temperature, and the water heater will continue to heat. If other safety measures fail at this time, the water heater is very likely to explode due to high temperature due to the failure of the thermostat.
2. Overheat protector
The overheat protector is the most critical safety component of the water heater. It is mainly used to prevent the water heater from exploding due to endless heating. For example, if the thermostat of the water heater is damaged and the water heater continues to heat, the water heater overheat protector will sense this and automatically cut off the power supply, so that the water heater stops working. It will also prevent the water heater from overheating and exploding due to constant heating.
0 3. Safety valve
12 The safety valve, also called the pressure relief valve, is the last safety measure for the water heater. Once the water heater thermostat is abnormal or the overheat protector is abnormal, the pressure relief valve will play a role at this time and will automatically relieve the pressure inside the water heater. Water will generally flow from the outlet of the pressure relief valve. This is a normal water heater pressure relief phenomenon. Once the water heater pressure relief valve is abnormal, the water heater will continue to heat, causing excessive internal pressure and causing the water heater to explode. 3
