One of the main assistants in everyday life and at work is natural gas. A modern person cannot imagine his life without him, but he can often cause many troubles. As a rule, cases of gas leakage in everyday life and at work were the cause of explosions and further fires. To avoid such tragic cases, you should buy and install a gas detector in a timely manner.

Safety First

This device is a mechanism whose main task is to detect household gas and other combustible mixtures in the air. As soon as the device detects a gas leak, it cuts off the gas supply and informs people about the occurrence of a life-threatening situation. A gas detector is a device without which it can be dangerous to be indoors. It avoids the tragic consequences that result from a leak.

Affordable and reliable

Gas detector "Gas 1" isa device that allows you to inform about the presence of combustible gas vapors in the air in residential and industrial premises. If a dangerous situation is suspected, the device gives a series of sound and bright light signals in the fire system, which allows you to take timely measures to prevent it.

Natural gas alarms have been installed in industrial premises for a long time, and more recently they have moved to residential areas. This allows you to ensure the safety in your own home. Because of this, almost the entire range of devices has undergone significant changes in many companies that specialize in the production of a device called a gas alarm. Its price has been greatly reduced in recent years, due to which such devices have become affordable for most people.

What else can alarms do?

Depending on the model you choose, the device will perform a certain set of functions. Many devices are equipped with a light indicator that allows you to notify visually of an increased concentration of hazardous gas. Usually the operation of the device is designed in such a way that the light alarm is accompanied by a high volume sound. A number of signaling devices boast the ability to connect a wide range of add-ons. For example, it can be a solenoid valve that will shut off the gas supply in an emergency.

More expensive models have the ability to connect to autonomous exhaust systems, which, whenin the event of an emergency, they turn on and allow you to clear the air in a short time. Signaling devices operate from 220 V, a similar power supply is required for additional devices. This allows you to install a warning system in almost all rooms that are equipped with a network connection. It can be either a residential building or an apartment, or an industrial premises.

Great opportunities

The combustible gas detector is a device that allows you to control the concentration of not just one gas in the air, but immediately a wide range of explosive substances. Such devices are on sale in many specialized stores, including on the Internet. If your home is equipped with a natural gas heating system, methane or propane may leak. If heating and cooking takes place with the help of an oven, then a situation may arise when the concentration of carbon monoxide in the air will be increased.

However, these points can be omitted if you choose a device that can capture several dangerous gases. This saves time and increases the safety of your premises. It should be noted that most stores that specialize in the sale of fire safety devices also offer installation services. They should not be neglected, as these are technically complex devices, the installation and configuration of which should be handled by professionals.

Not only to inform, but also to save

The solenoid valve isa device that usually includes a gas alarm. A household appliance with this addition is very useful, because its task is not only to warn people about a possible emergency, but also to take measures to solve it. If the detector has caught vapors of hazardous substances in the air, then the valve immediately comes into play, which automatically shuts off the gas supply to a given sector or to the entire room. By varying the location of the valve, you can choose where the gas will flow after shutting off.

The main differences between such devices are the diameter, maximum pressure and type of valve supply. In domestic conditions, valves are used, the diameter of which varies from 15 to 25 cm. They require a 220 V socket to power them. The pressure they can withstand does not exceed 500 mbar.

There are two types of valves: impulse and normally closed. All of them are equipped with the ability to manually activate, which allows you to limit the gas supply even during a complete blackout of the building.

How does it work?

After the gas alarm has been triggered, a short-term voltage is applied to the pulse type valve, which is enough to shut off the gas supply. To maintain the valve in the open state does not require electricity, which is the main advantage of the device. The correct operation of the valve, which is of the normally closed type, is possible only with a continuous supply of voltage. That is why in domestic use it is enough to installpulse device, since its operation does not directly depend on the power source. This avoids the consequences of frequent power outages, which are expressed in the fact that when there is no voltage on the valve, it automatically closes. At the same time, you will be left without electricity and without gas.

Special hazard - carbon monoxide

The carbon monoxide detector is a device whose primary task is to continuously and automatically monitor the excess of the optimal amount of this substance in the ambient air. This signaling device can be used both in residential premises and in residential, administrative and public buildings. This is necessary if they have heating appliances or gas stoves. It is also advisable to use them in garages, mines, wells and where there is a possibility of accumulation of carbon monoxide vapors.

The standard kit of the signaling device includes a power supply unit designed to connect the signaling devices, signaling blocks, the number of which is equal to the number of installation points of the signaling devices, connection cables and a shut-off valve. The device controls the concentration of carbon monoxide at two thresholds: the first is set to 200 mg / cu. m, and the second - at 100 mg / cu. m. The warm-up time is around 3 minutes, while the device has a very fast response to air pollution. The operating temperature range is from 0 to 50 degrees Celsius. The signaling device emits a sound signal with a volume level of 80 dB and has a degree of protection IP42. Average life of the signaling deviceis 10 years, and the sensor is 5.

Features of operation

During operation, the device monitors the level of carbon monoxide in the air. When the threshold is exceeded, an alarm is triggered and the status indicator glows bright red and beeps. If the gas concentration falls below the first threshold, then the alarm is completely disabled. If the dangerous level exceeds the second threshold, an alarm is activated: the indicator starts flashing red and is accompanied by a two-tone sound signal. The alarm automatically turns on the exhaust systems and closes the valves, if any.

Portable versions

SGG gas detector is a portable device that allows you to control the concentration of combustible gas vapors in the air. The device continuously scans the concentration of gases in the air and, if the norm is exceeded, gives out sound and light signals. Applications:

  • enterprises specializing in the extraction and processing, as well as the transportation and storage of natural gas, oil and petroleum products;
  • industrial enterprises whose activities are related to the production of varnishes and paints, as well as sewers, boiler rooms and alcohol storage warehouses;
  • welding in the immediate vicinity of flammable canisters or containers;
  • river and sea ports, as well as ships and tankers;
  • stations specializing in the production of hydrogen and oxygen in cylinders.

The device works as an individual type of gas analyzer. Sampling is carried out by diffusion method. The device operates according to the thermochemical principle. Its main advantage is mobility, which allows you to quickly determine the concentration of hazardous gases in almost any room without installing bulky equipment.

What is the result?

The gas leak detector is available on the market in several different modifications, and all of them meet the requirements of the state standard (GOST). The device is equipped with a memory in which all data for the last month is stored. Their recording takes place at a certain interval, as a rule, it is one minute. Using the USB interface, there is a connection with a computer, which receives the results, where they are analyzed. Buy it or not - everyone decides for himself. However, do not forget that the safety of you and your loved ones may be at stake.
