Leakage essence and its feature, a kind of mode detected based on flow, temperature is provided, the differentiation of gas leakage is carried out,
It effectively avoids avoiding the safety problem that gas leakage may cause while wrong report.
The utility model uses a kind of following technical scheme: temperature-flow detection formula Household gas warner, including detection
Device and warning device, the detection device contain temperature-detecting device and flow detector two parts, at the same detect temperature,
Alarm criteria of two parameters of flow as warning device.Flow detector is mounted on burning line, and it is total to be located at combustion gas
Between gate and gas furnace, temperature-detecting device is mounted near combustion chamber.Temperature, the sending of flow signal and reception pass through
Wireless device is realized.
The flow detector includes power supply, volumetric flowmeter, magnet-sensitive switch, wireless signal generator.The appearance
Product formula flowmeter uses the volume-displacement of the counter containing idler wheel, and a magnet is placed at the minimum value of idler wheel counter, and
The external signal circuit containing magnet-sensitive switch.The magnet-sensitive switch uses tongue tube.
The temperature-detecting device includes power supply, thermostat relay, wireless signal generator.The thermostat relay and nothing
Line signal generator is connected directly.
The warning device includes power supply, temperature signal receiving module, flow signal receiving module, alarm, controller,
The temperature signal receiving module, flow signal receiving module are separately connected controller, the external alarm of controller.The alarm
Device uses buzzer.
When the utility model at work, it can determine whether building gas pipe, service pipe, indoor pipe has combustion gas logical by consumed flow signal detection
It crosses；It can determine whether normal use gas appliance by temperature signal detection, when flow signal detects, do not have in indoor fuel gas pipe
There is fluid flowing, illustrates not leak, therefore do not need to alarm；When flow signal detects indoor fuel gas Guan Zhongyou fluid
Flowing there is two kinds of situations 1, normal use burner 2, leak, and need temperature parameter also for both of these case to sentence
Disconnected: 1, normal use burner: when normal use burner, chamber temperature changes, so having flow in pipe in this situation
Consumption belongs to normal phenomenon；2, leak: when gas leakage occurs, chamber temperature will not change, so herein
In the case of, managing interior flowing should belong to gas leakage, need to alarm.
The utility model has the beneficial effects that the utility model Household gas warner carries out the variation of temperature, flow
Detection, efficiently avoids the catalytic combustion method gas sensor of traditional alarm when carrying out combustible gas monitoring, may be right
This defect is reported in the generations such as the acetic acid, ethyl alcohol, the oil gas that volatilize in cooking process by mistake.Essence according to indoor fuel gas leakage is special
Sign, while temperature-detecting device and flow detector are set, wrong report problem caused by directly monitoring fuel gas is avoided,
And can more accurately it judge for whether combustion gas leaks, thus keep the alarm for gas leakage more accurate, with
Exempt to cause unnecessary loss.
