Description
Technical field
The utility model relates to technical field of safety protection, specifically a kind of combustible gas detecting alarm.
Background technique
Combustible gas probe is to single or many combustible gases concentration-response detector.Combustible gas probe has
Catalytic type, infrared optics type two types.Catalytic type combustible gas probe is to utilize the resistance after the heating of refractory metal platinum filament
Variation is to measure combustable gas concentration.When fuel gas enters detector, cause oxidation reaction (nonflame combustion on platinum filament surface
Burn), the heat generated increases the temperature of platinum filament, and the resistivity of platinum filament just changes.Infrared optics type is using red
Outer sensor detects the alkanes fuel gas of site environment by the principle of absorption of infrared light sources.
Fire is one of the common disaster for threatening human life's safety, and causes fire incident by gas leakage
One of most common reason, therefore with the development of science and technology the equipment for gas leakage early warning is also being continuously improved, it reduces
The incidence of fire also brings stabilization for country and society.
Currently, combustible gas detector and alarm on the market is all independent structure mostly, and structure is complicated, and price is high
Expensive, stability is poor, and installation is inconvenient, some are even alarmed not in time, cannot carry out precautionary measures in time.
Utility model content
Place in view of the deficiency of the prior art, the utility model are intended to provide a kind of combustible gas detecting alarm
Device.
In order to solve the above technical problems, a kind of combustible gas detecting alarm provided by the utility model, it is characterised in that:
Including main casing, two symmetric side of main casing is provided with cable entrance hole, is provided with display screen on the main casing,
Display screen upper end two sides are provided with early-warning lamp, and display screen lower end two sides are provided with alarm outlet, the main casing
Downside is provided with sensor, and the sensor lower end is provided with gas chamber, and sensor is wholely set with gas chamber.
Wherein, stomata is provided on the gas chamber.
Wherein, the display screen is liquid crystal display.
Wherein, the main casing uses the shell of cast aluminium die cast.
Wherein, fixing piece is provided on the main casing.
Wherein, the fixing piece is screw, and the fixing piece quantity is no less than 6.
The utility model has the beneficial effects that the utility model combines combustible gas detector and alarm, and the multiple letter of structure
Single, cheap, stability is good, installation convenience, can and alarm, allow user to carry out safety precaution in advance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
