Abstract
The invention relates to a gas leakage detector which comprises a smell sensor (1), a comparison amplifier (2), a control part (3) and an alarm (4), wherein the smell sensor receives and transmits gas smell; the comparison amplifier receives signals transmitted by the smell sensor (1) and carries out comparative amplification on the weak signals; the control part analyzes the signals transmitted by the comparison amplifier (2), and then sends an alarm signal to the alarm (4) in case of abnormal smell or sends a non-alarm signal to the alarm (4) in case of normal smell; and the alarm gives an alarm according to the signals sent by the control part (3). The gas leakage detector can achieve convenient installation and wiring and automatic routing inspection, locking and setting; and when concentration of the detected gas in an environment reaches or exceeds a preset alarm value, the alarm can give out a sound-light alarm immediately to remind a user of taking safety measures. The detector can be widely applied to hazardous sites where inflammable, explosive and toxic gas exists in gas, petroleum, chemical industry, metallurgy and other fields.
Description
Technical field
The present invention relates to a kind of pick-up unit, especially relate to a kind of gas leakage detector.
Background technology
Coal gas is the daily necessities of common people's herbal, but because some gas pipings have been old fogeys long neglected and in disrepair, when often having leakage, if we can not in time detect coal gas leakage was arranged this moment, then is easy to cause very big personnel to do to die.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of gas leakage detector, and this device can be very sensitive in gas leak senses and send chimes of doom, avoids the generation of accident.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
Gas leakage detector includes with lower member:
Be used to receive and transmit the smell sensor of coal gas smell;
Receive the signal that smell sensor sends, and the comparison amplifier that feeble signal is compared and enlarged;
Signal to relatively amplifier transmission is analyzed, if unusual odor then sends the newspaper alerting signal to alarm; If normal smell then sends the control part of non-alarm signal to alarm;
The alarm that the signal that sends according to control part is reported to the police.
Advantage and effect that the present invention had are:
Gas leakage detector of the present invention is installed and is arranged net conveniently, each passage shows automatically, patrols and examines automatically, locks, sets, when the concentration of probe gas in the environment meets or exceeds when presetting alarming value, alarm sends sound and light alarm immediately, to remind the user to take safety measures, and drive air draft, cut-out, spray system, prevent blast, fire, intoxication accident, thereby guarantee safe production.Product is widely used in combustion gas, oil, chemical industry, metallurgy etc. and has hazardous area inflammable, explosive, poisonous gas.The present invention is of many uses, also can detect: flammable toxic and harmfuls such as rock gas, liquefied gas, coal gas, hydrogen, acetylene, carbon monoxide, sulfuretted hydrogen, chlorine, bromine gas, sulphuric dioxide, ammonia, coal gas, toluene, methane-monochloro methane, methyl alcohol, ethanol, liquefied ammonia, liquid chlorine-carbon dioxide, oxygen, alcohol, benzene, dimethylbenzene, gasoline, diesel oil, paint, solvent oil, methyl ether.
Description of drawings
Fig. 1 is the structured flowchart of gas leakage detector of the present invention.
Wherein: smell sensor 1; Comparison amplifier 2; Control part 3; Alarm 4.
Embodiment
Gas leakage detector includes with lower member:
Be used to receive and transmit the smell sensor 1 of coal gas smell;
Receive the signal that smell sensor 1 sends, and the comparison amplifier 2 that feeble signal is compared and enlarged;
Signal to relatively amplifier 2 transmission is analyzed, if unusual odor then sends the newspaper alerting signals to alarm 4; If normal smell then sends the control part 3 of non-alarm signal to alarm 4;
The alarm 4 that the signal that sends according to control part 3 is reported to the police.
Claims (1)
1. gas leakage detector is characterized in that including with lower member:
Be used to receive and transmit the smell sensor (1) of coal gas smell;
Receive the signal that smell sensor 1 sends, and the comparison amplifier (2) that feeble signal is compared and enlarged;
Signal to relatively amplifier (2) transmission is analyzed, if unusual odor then sends the newspaper alerting signal to alarm (4); If normal smell then sends the control part (3) of non-alarm signal to alarm (4);
