燃气热水器燃气阀的安全控制电路设计

摘要

Gas water heater gas valve usually MCU driver (which we usually refer to a solenoid valve) to control the gas off. Once the MCU fails, the gas valve will not work, so the gas-off is out of control, can easily lead to accidents. To compensate for this deficiency, the control circuit for a gas water heater gas valve has been improved to prevent accidents.%燃气热水器通常采用MCU驱动燃气阀（即我们通常所说的电磁阀）来控制燃气的通断。一旦MCU出现故障，燃气阀将无法正常工作，使燃气的通断处于失控状态，容易引发安全事故。为弥补这一缺陷，对燃气热水器燃气阀的控制电路进行了改进，防止安全事故发生。
