Abstract
The invention provides gas leakage detection equipment of a gas water heater. When a water heater water outlet water flow speed measuring unit continuously senses that the water flow speed in a hot water outlet is lower than the preset water flow speed within the persistent scheduled time, the water heater water outlet water flow speed measuring unit sends a gas flow detection signal to a control unit; when the control unit receives the gas flow detection signal from the water heater water outlet water flow speed measuring unit, a gas outlet gas flow measuring unit is started, and therefore the gas flow speed of flowing gas in a gas connector is sensed; when the gas outlet gas flow measuring unit detects that the gas flow speed of the water in the gas connector is higher than the preset flow speed, a gas alarm signal is sent to the control unit; when the control unit receives the gas alarm signal from the gas outlet gas flow measuring unit, a reminding starting signal is sent to a reminding unit to start the reminding unit, and therefore the reminding unit sends out reminding information.

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.
