Combustible gas alarms are gas leak detection alarms. When flammable or toxic gas leaks in the industrial environment, when the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the combustible gas alarm will send out an alarm signal to remind the work to take safety measures. The device is equivalent to an automatic fire extinguisher, which can drive exhaust, cut off, and sprinkler systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. Combustible gas alarms can measure various gas concentrations. Often used in chemical plants, oil, gas stations, steel mills and other places where there are gas leaks.
Application in the home
(1) Centralized control of apartment buildings This is the most typical application of combustible gas alarms in civil use, as long as civil residential buildings equipped with building managers can use this method. The alarm is installed in each residential unit and outputs a centralized monitoring panel connected to the duty room. Once a gas leak occurs in a certain unit, the flammable gas alarm immediately operates and outputs a signal, which can be displayed on the monitoring panel.
(2) Combine with the burning appliance This is to connect combustible gas alarms with gas appliances such as gas water heaters, cooking appliances, exhaust hoods, etc. When there is a gas leak, the alarm operates to emit audible and visual alarms and output electrical signals simultaneously. . If it is matched with a range hood, the range hood power is turned on, and if the leakage gas is discharged outwards, such as connecting with a water heater or a cooker, the action of the gas path can be achieved by operating a solenoid valve connected to the gas pipeline. There is also an alarm device that is directly connected to the gas meter. When an alarm occurs, the solenoid valve in the gas meter acts to shut off the gas source. (3) Separate use This is the simplest method of using a combustible gas alarm. When the flammable gas leak reaches a certain concentration, the alarm sounds an audible and visual alarm. This alarm mode requires that someone in the house must immediately take measures to cut off the air source manually.
Installation Precautions
(1) The alarm probe is mainly a detection element that is in contact with the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a sphere. On the outer surface thereof, platinum, palladium, and other rare metals are attached. Therefore, be careful when installing to avoid damaging the probe.
(2) The mounting height of the alarm should be determined based on the nature of the gas.
(3) The alarm is a safety instrument, sound and light display function, and it should be installed in the place where the staff can easily see and hear, so as to eliminate the hidden trouble in time.
(4) There must be no strong electromagnetic fields (such as high-power motors and transformers) that affect the operation of the instrument around the alarm.
(5) The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the measured gas density is less than the air density, the probe should be installed 30cm away from the roof, downward; otherwise, the probe should be installed 30cm away from the ground, upward direction
