Description
Technical field
The present invention relates to gas burning field, more particularly to a kind of security system for preventing gas leakage and method and
Judge the method for gas leakage position.
Background technique
With economic and science and technology fast development, people are more next to the raising of quality of life and the improvement of living environment
More pay attention to, the use of the clean energy resourcies such as liquefied gas, coal gas is brought more convenient, and is also improved The Surroundings in Cities, is reduced
Discharge, reduces environmental pollution, but also brought potential danger.Wherein gas leakage is main danger source, combustion
Expect in use, if valve, connection hose, pipe joint and use equipment damage or poorly sealed, leak, less serious case
It can cause to be poisoned, severe one causes fire or explosion, threatens the safety of life and property of people.
Gas leakage the reason is as follows that:
It is the leakage of gas-fired equipment, such as gas-cooker, gas heater first, and the reason of cause gas-fired equipment to leak
Including 1. artificial origin, leakage caused by burnt gas valve is not closed completely；2. extraneous factor, gas-fired equipment is working, outside
Boundary's factor leads to leakage caused by fray-out of flame；3. Equipment, gas-fired equipment is unqualified or the damage of some pieces of equipment, sealing
It is not tight, connect after gas leakage caused by itself.
Followed by pipe leakage is let out as caused by the connection unqualified damage of gas-fired equipment and the hose of house lead in pipeline itself
The hose of leakage, connection gas-fired equipment and house lead in pipeline leaks caused by damaging because of extraneous factor, connects gas-fired equipment and home-in-pipe
The hose in road because aging without replacing in time caused by leak, hose is connect or hose and gas-fired equipment with house lead in pipeline in use
Connection does not connect, and leaks caused by poorly sealed.
It is certainly not limited to above two leakaging cause, there are also other possible leakages.
Traditional gas-fired equipment does not have any safety measure, when gas-fired equipment is not closed completely or because of extraneous factor fire
Flame extinguishes, and will result in leakage, and the manufacturer of gas-fired equipment makes gas-fired equipment from provided with electromagnetic valve and temperature by technological improvement
Sensor, realization principle are equipment igniting, and Flame Heating Temperature sensor generates potential difference and drives when temperature is more than certain numerical value
Solenoid valve is opened, conversely, working as fray-out of flame, temperature sensor cannot generate enough potential differences to open solenoid valve, solenoid valve
Close cutting pipeline.This prevents gas-fired equipments because being not closed completely or letting out because of caused by fray-out of flame caused by extraneous factor
Leakage.But even if technological improvement, leaks and do not work caused by the reasons such as the poorly sealed and aging leakage of connection hose.
Additional combustion gas detecting alarm, combustion gas detecting alarm detect gas leakage and just will call the police, and notify personnel to close
Valve closing door, windowing ventilation, combustion gas detecting alarm alarm explanation had leak and reach must concentration, live people can be made
Member sucks many toxic gases and be easy to cause personnel's poisoning or dead.But if nobody will so leak always within doors,
Serious consequence can be brought.
Additional combustion gas detecting alarm and stop valve unit equipment, fuel gas alarm detect gas leakage and just will call the police,
And stop valve is given signal simultaneously, cutting fuel gas pipeline prevents combustion gas from continuing to leak, hears that the personnel within doors of alarm will be rapid
It comes to open a window and divulge information.This technology illustrates that alarm equipment alarm has had leakage, and Field Force can suck many toxic gases, holds
It easily causes personnel to be poisoned, threatens the life of personnel.
