Description
Technical field
The utility model is related to coal gas detection technique fields, and in particular to a kind of gas leakage alarm device.
Background technology
Almost every household is all using coal gas, but gas leak problem can not be ignored.Personnel occur because of gas leak
Injures and deaths, the case of property loss are not within minority, and there are two the danger that gas leak is easy tod produce because that cannot prevent in time, when
Gas leak easilys lead to people's anthracemia, threat to life；It is easily sent out second is that gas leak reaches a certain amount of chance open fire
Raw explosion or fire, cause damages safely to people and have property loss.Household fuel gas use device currently on the market is big
More ignition switch that need to only close coal gas use device when not in use are without closing gas supply device master switch, people
Also the custom for keeping gas supply device master switch normally opened has been formed, for connecting coal gas use device and gas supply device,
But being to turn on the pipeline of coal gas use device and gas supply device, there are life cycles, once rupture, aging, mesh occur for pipeline
Preceding warning device in the market only has warning function, can not prevent gas leak in time.
Utility model content
The purpose of this utility model is to provide a kind of gas leakage alarm devices, can be with when gas leak occurs
Automatic alarm, while coal gas is automatically closed, or coal gas is turned off manually, gas leak is prevented in time.
To achieve the above object, the utility model provides the following technical solutions：
A kind of gas leakage alarm device, including gas supply device, coal gas use device, controller, the coal gas supply
It answers device to be connect by pipeline with coal gas use device, is equipped with check valve one, two three-way electromagnetic valve, list on the pipeline successively
To valve two, pressure sensor, the check valve one is arranged on pipeline close to one end of gas supply device, the pressure sensing
Device is arranged on pipeline close to one end of coal gas use device, and the check valve one and two three-way electromagnetic valves are externally provided with protection
Shell, both ends are equipped with installation set in the protective shell, and the input terminal of the pressure sensor and controller is electrically connected, the control
The output end of device processed is electrically connected with alarm, two three-way electromagnetic valves successively.
Preferably, protective shell is fixedly connected by the installation set with pipeline.
Preferably, the protective shell is equipped with handle.
Preferably, described handle one end is connect by connecting rod with two three-way electromagnetic valves.
Compared with prior art, the utility model has the beneficial effects that：
When coal gas does not leak, during using coal gas with or without using coal gas, pressure sensor has fixation
Value range, at this time alarm do not work, two three-way electromagnetic valves are kept open；When coal gas leaks, coal is being used
Gas is with or without using during coal gas, and pressure sensor numerical value is not in the value range of former setting, and pressure sensor will at this time
For data transmission to controller, controller sends out instruction to alarm and two three-way electromagnetic valves switches, and alarm, which is in, at this time reports
Alert state sends out alarm sound, while two three-way electromagnetic valves are closed, and gas leak stops.The opening and closing of two three-way electromagnetic valves
It can be by artificially being controlled either manually or by handle.So when gas leak occurs, the utility model can be while automatic with automatic alarm
Coal gas is closed, or coal gas is turned off manually, prevents gas leak in time, is easily installed in inside family, prevents due to gas leak
Caused by accident occur.

Specific implementation mode
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 describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Refering to Figure 1, a kind of gas leakage alarm device, including gas supply device 1, coal gas use device 2, control
Device 3 processed, the gas supply device 1 are connect with coal gas use device 2 by pipeline 4, are equipped with check valve on the pipeline 4 successively
One 5, two three-way electromagnetic valves 6, check valve 27, pressure sensors 8, the check valve 1 are arranged on pipeline 4 close to coal gas
One end of feeding mechanism 1, the pressure sensor 8 is arranged on pipeline 4 close to one end of coal gas use device 2, described unidirectional
Valve 1 and two three-way electromagnetic valves 6 are externally provided with protective shell 9, and both ends are equipped with installation set 10, the pressure in the protective shell 9
The input terminal of sensor 8 and controller 3 is electrically connected, the output end of the controller 3 successively with 11, two one energizations of alarm
Magnet valve 6 is electrically connected, and protective shell 9 is fixedly connected by the installation set 10 with pipeline 4, and the protective shell 9 is equipped with handle 12, institute
12 one end of handle is stated to connect with two three-way electromagnetic valves 6 by connecting rod 13.
Operation principle：When coal gas does not leak, during using coal gas with or without using coal gas, pressure sensing
Device 8 has fixed range value, and alarm 11 does not work at this time, and two three-way electromagnetic valves 6 are kept open；When coal gas leaks
When, during using coal gas with or without using coal gas, 8 numerical value of pressure sensor is not in the value range of former setting, at this time
Pressure sensor 8 transfers data to controller 3, and controller 3 sends out finger to alarm 11 and two three-way electromagnetic valve 6 switches
It enables, alarm 11 is in alarm condition and sends out alarm sound at this time, while two three-way electromagnetic valves 6 are closed, also can be by artificial
Manual operation handle 12 closes two three-way electromagnetic valves 6, prevents gas leak in time.After accident to leak the coal gas is disposed
When being continuing with coal gas, two three-way electromagnetic valves 6 can be opened by manually operated handle 12.
