Abstract
A domestic natural gas alarm belongs to a domestic fuel gas safety alarm device and comprises a first detection end (1) and a second detection end (2), wherein the first detection end (1) is slantways placed above a furnace (3), and a 45-degree included angle is formed between the first detection end (1) and the furnace (3); and the second detection end (2) is arranged on the same plane with the furnace (3), and the distance between the second detection end (2) and the furnace (3) is 1 m. With the utilization of the domestic natural gas alarm, an acousto-optic alarm is given when the natural gas is leaked, the alarm also can be turned off when the concentration of methane is within an explosion range to avoid an explosion generated by electric sparks.
Description
Technical field
A kind of natural gas in home fuel gas alarm belongs to the Domestic gas safety alarm device.
Background technology
Coal gas give day daily life brought a lot of convenience.Yet the coal gas improper use also is easy cause danger, and at first, coal gas is poisonous, the people is poisoned deadly, in addition, when the ratio of coal gas and air acquires a certain degree, easily blasts, and this just needs a kind of alarm that the concentration of coal gas is detected.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of natural gas in home fuel gas alarm, and this alarm can send sound and light alarm in gas leak, also can close alarm in explosive range at methane concentration, prevents the blast that electric spark causes.
The object of the present invention is achieved like this:
A kind of natural gas in home fuel gas alarm comprises the first end of probe and the second end of probe, and wherein, the first end of probe is placed on 45 ° of directions of stove and accessory oblique upper, and the second end of probe is placed on the position far away apart from stove and accessory 1m with the stove and accessory same level.
Above-mentioned a kind of natural gas in home fuel gas alarm, also comprise master controller, and the first end of probe is provided with the first sensing methane concentration device, the second end of probe is provided with the second sensing methane concentration device, and the first sensing methane concentration device and the second sensing methane concentration device are connected to the input port of master controller.
Above-mentioned a kind of natural gas in home fuel gas alarm, the output terminal of described master controller is connected with loudspeaker and light emitting diode.
Above-mentioned a kind of natural gas in home fuel gas alarm also includes contactor and is connected on the main line, and described switch is connected with the output terminal of described master controller.
Because natural gas in home fuel gas alarm of the present invention comprises the first end of probe and the second end of probe, wherein, the first end of probe is placed on 45 ° of directions of stove and accessory oblique upper, and the second end of probe is placed on the position far away apart from stove and accessory 1m with the stove and accessory same level; This design also can be closed alarm at methane concentration so that alarm of the present invention can send sound and light alarm in gas leak in explosive range, prevent the blast that electric spark causes.
Description of drawings
Fig. 1 is natural gas in home fuel gas alarm schematic diagram of the present invention.
Among the figure: 1 first end of probe, 2 second end of probe, 3 stove and accessorys, 4 first sensing methane concentration devices, 5 second sensing methane concentration devices, 6 master controllers, 7 loudspeakers, 8 light emitting diodes, 9 switches.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in further detail.
The natural gas in home fuel gas alarm schematic diagram of the present embodiment as shown in Figure 1, this alarm comprises the first end of probe 1 and the second end of probe 2, master controller 6, wherein, the first end of probe 1 is placed on 45 ° of directions of stove and accessory 3 oblique uppers, the second end of probe 2 is placed on the position far away apart from stove and accessory 31m with stove and accessory 3 same levels, the first end of probe 1 is provided with the first sensing methane concentration device 4, the second end of probe 2 is provided with the second sensing methane concentration device 5, the first sensing methane concentration device 4 and the second sensing methane concentration device 5 are connected to the input port of master controller 6, the output terminal of master controller 6 is connected with loudspeaker 7, light emitting diode 8 and be connected to switch 9 on the main line.
When in use, when the first sensing methane concentration device 4 of the first end of probe 1 continues to reach high concentration, then send signal to master controller 6, when the second sensing methane concentration device 5 of the second end of probe 2 reaches high concentration, then send signal to master controller 6, master controller 6 obtains the backward loudspeaker 7 of signal and light emitting diode 8 sends alerting signal, and loudspeaker 7 and light emitting diode 8 are sounded respectively and reported to the police and the light warning.
When if the second sensing methane concentration device 5 of the second end of probe 2 reaches dangerous concentrations, then send signal to master controller 6, master controller 6 obtains the backward switch 9 of signal and sends signal, and switch 9 cuts out the main line electric current, the time whole alarm power down, prevent that electric spark from setting off an explosion.
Described high concentration is 2%, and dangerous concentrations is 5%.
