Description
Technical field
The utility model belongs to the gas-fired equipment technical field, is specifically related to a kind of domestic gas and reveals warning and control device.
Background technology
Along with improving constantly of China's living standards of the people, combustion gas has become the main energy sources of town dweller's life, the user of combustion gas people also bring potential safety hazard in life time, because combustion gas be cannot see, be can not touch, be difficult for being found when occurring leaking, often cause the security incidents such as gas poisoning, fire.Therefore, find early gas leakage, reaching alarm and cutting off source of the gas is the effective measures of avoiding because of the security incident of gas leakage initiation.Prior art is the gas that adds special odor in combustion gas, and people are by the leakage of detected by scent combustion gas, but there is defective in this technical measures, the one, can not find early, in addition as that live is handicapped old man, even found gas leakage, also unable taking measures.
The utility model content
For the defective of prior art, the purpose of this utility model is to propose a kind of gas leakage of finding early, reaches alarm and cuts off the Fuel Gas Leak Alarm of source of the gas.
The technical solution of the utility model is achieved in that a kind of domestic gas leakage alarm, it is characterized in that: comprise the combustion gas sensing unit, be used for surveying gas leakage; Alarm unit is used for sending warning; The fuel gas shutoff unit is used for cutting off fuel gas source; Control module is electrically connected with described combustion gas sensing unit, alarm unit and fuel gas shutoff unit respectively, is used for receiving the signal of described combustion gas sensing unit and controls described alarm unit and the fuel gas shutoff unit.
Principle of work of the present utility model is: the combustion gas sensing unit sends signal when detecting gas leakage, control module receives the backward alarm unit of gas leakage signal and give an order in the fuel gas shutoff unit, alarm unit sends warning subsequently, fuel gas shutoff unit cut-out source of the gas.
Described combustion gas sensing unit is catalytic combustion type sensor, be characterized in that linear good, the index of output signal is reliable, low price, without intersecting interference with other incombustible gas.
Described alarm unit adopts hummer to reduce costs.
Described fuel gas shutoff unit adopts solenoid valve, and its reliable operation, volume are little.
Described control module comprises that signal reception and amplifying circuit, testing circuit and signal send circuit, signal receives and amplifying circuit also amplifies this signal for the signal that reception combustion gas sensing unit sends, testing circuit is compared the signal that receives with the standard signal of setting, signal sends circuit and sends fill order to alarm unit and fuel gas shutoff unit.
The power supply of this domestic gas leakage alarm can adopt household electricity, also can adopt battery.It is simple in structure adopting the advantage of battery, easy for installation.
The utility model can become one with gas meter, also can make independent product.Make outer box of independent product needed all parts are installed, this outer box also is provided with opening and makes outside combustion gas sensing unit and alarm unit be exposed to.
The utility model is simple in structure, volume is small and exquisite, cheap, easy for installation, be specially adapted to family and install.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Domestic gas leakage alarm as shown in Figure 1 comprises combustion gas sensing unit 1, is used for surveying gas leakage; Alarm unit 2 is used for sending warning; Fuel gas shutoff unit 3 is used for cutting off fuel gas source; Control module 4 is electrically connected with described combustion gas sensing unit 1, alarm unit 2 and fuel gas shutoff unit 3 respectively, is used for receiving the signal of described combustion gas sensing unit 1 and controls described alarm unit 2 and fuel gas shutoff unit 3.
Described combustion gas sensing unit 1 adopts catalytic combustion type sensor, be characterized in output signal linear good, index reliable, low price, without intersecting interference with other incombustible gas.
Described alarm unit 2 adopts hummer to reduce costs.
Described fuel gas shutoff unit 3 adopts solenoid valves, and its reliable operation, volume are little.
Described control module 4 comprises that signal reception and amplifying circuit, testing circuit and signal send circuit, signal receives and amplifying circuit also amplifies this signal for the signal that reception combustion gas sensing unit 1 sends, testing circuit is compared the signal that receives with the standard signal of setting, signal sends circuit and sends fill order to alarm unit 2 and fuel gas shutoff unit 3.
This domestic gas leakage alarm uses battery 5 as its power supply, makes this domestic gas leakage alarm simple in structure, easy for installation.
The utility model adopts outer box that all parts are installed, and this outer box is provided with opening and makes outside combustion gas sensing unit and alarm unit be exposed to.
The course of work of the present utility model is: when gas leakage occurring, the inductive reactance of catalytic combustion type sensor and the combustion gas generation flameless burning in environment, temperature of combustion changes the resistance of inductive reactance, breaks the Wheatstone bridge balance, makes it the current signal of stable output; Control module receives this current signal and amplifies, then compare with the standard value of setting, as less than standard value, think the normal leakage of using, do not send executive signal, if more than or equal to standard value, illustrate that gas leakage has reached the degree that causes security incident, send executive signal, namely be connected with solenoid valve with hummer and be connected to realize to report to the police and the cut-out source of the gas by connecting battery.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
