Abstract
The invention provides a gas leakage detection device for a gas water heater. When a water heater water outlet temperature measuring unit continuously senses that the water temperature at a hot water outlet is lower than a preset temperature in a lasting preset time period, the water heater water outlet temperature measuring unit sends a gas flow detection signal to a control unit; the control unit starts a gas outlet gas flow measuring unit when receiving the gas flow detection signal from the water heater water outlet temperature measuring unit so as to sense the airflow velocity of water at a gas connector; besides, when the gas outlet gas flow measuring unit detects that the flowing airflow velocity of gas at the gas connector is larger than a preset flow velocity, the gas outlet gas flow measuring unit sends a gas warning signal to the control unit; the control unit sends a reminding starting signal to a reminding unit when receiving the gas warning signal from the gas outlet gas flow measuring unit so as to start the reminding unit and make the reminding unit send out a reminding message.

Gas heater is also known as gas water-heating furnace, and it refers to, using combustion gas as fuel, pass through combustion heating
Mode transfers heat to flow through in the cold water of heat exchanger to reach to prepare the one of the purpose of hot water
Gas appliance.
The basic functional principle of gas heater is that cold water enters water heater, flows through Water-gas linkage valve body and exists
Under the certain pressure difference effect of circulating water, promote Water-gas linkage valve, and promote DC source simultaneously
Microswitch, by power on starting impulse lighter, meanwhile opens combustion gas gas transmission electromagnetic valve
Door, continues automatically again to light a fire by pulse igniter, until igniting is successfully entered normal operating conditions
Till, this process maintains 5～10 second time the most continuously, when gas heater is in work process or igniting
Process occur hydropenia or hydraulic pressure deficiency, short of electricity, lack combustion gas, hot water temperature is too high, unexpected puts out fire etc.
During phenomenon of the failure, pulse igniter, by the signal by detection inductive needle feedback, automatically cuts off power supply,
Original normally close valve state is replied at once, the most just in the case of the short of electricity supply of combustion gas gas transmission electromagnetic valve
It is to say now to have been turned off fuel gas path, closes gas heater and play safeguard protection effect.
