Detailed ways

As shown in Figure 1, the utility model discloses a gas valve automatic detection and alarm device, the gas valve automatic detection and alarm device is connected with household gas equipment, and the household gas equipment can be a gas stove or a gas water heater. Gas equipment also includes gas pipelines.

The main controller of the gas valve automatic detection and alarm device, a detection system, an alarm system, a power module and an interaction module.

The main controller can receive relevant information collected by the detection system and analyze and process accordingly, so as to drive the alarm system to work. The main controller is preferably a single-chip microcomputer widely used in such detection and alarm devices at present.

The detection system is connected with the main controller to detect whether the gas in the gas equipment leaks, and the detection system includes a gas flux detector, a combustible gas detector and a gas detector. The gas flux monitor is arranged in the gas pipeline, and the combustible gas detector and the gas detector are arranged outside the gas pipeline. The gas flux detector can detect the gas flux in the gas pipeline. The flammable gas detector can detect the flammable gas content (LEL) in the environment. The gas detector is capable of detecting whether gas is escaping.

The alarm system includes a gas cut-off device, an audible and visual alarm and a communication alarm installed in the environment where the gas valve automatic detection alarm device is located.

The gas cut-off device includes a relay, a gas solenoid valve and an exhaust fan. The relay is electrically connected to the main controller and is driven to work by the main controller. The gas solenoid valve is installed in the gas equipment. The main controller can realize the switching of the gas solenoid valve by controlling the operation of the relay. The exhaust fan is installed in the environment where the gas valve automatic detection and alarm device is located and is electrically connected with the relay. The relay can start the exhaust fan to work while closing the gas solenoid valve.

The acousto-optic alarm is provided with an LED light and a miniature horn, which can generate audible-visual alarm information. The communication alarm device is provided with a communication module that can be connected to a communication network and a positioning module that records the position information of the gas valve automatic detection alarm device.

The power module can provide power for the gas valve automatic detection and alarm device.

The interaction module is connected with the main controller to realize the function of human-computer interaction.

The working process of the utility model is briefly described as follows: when the gas valve automatic detection and alarm device starts to work, the main controller can receive the relevant information collected by the detection system.

When the gas flux detector detects an abnormal change in the gas flux in the gas pipeline, and the gas detector detects that there is gas escape, but the value of the combustible gas content (LEL) detected by the combustible gas detector When there is no change, it means that there is a slight gas leakage. At this time, the main controller controls the sound and light alarm to work, and the sound and light alarm sends out an audible and visual alarm signal.

When the gas flux detector detects an abnormal change in the gas flux in the gas pipeline, and the gas detector detects that there is gas escape, but the value of the combustible gas content (LEL) detected by the combustible gas detector When it is 0.1-20%, it means that the gas has a moderate leakage. At this time, the main controller controls the operation of the audible and visual alarm and the gas cut-off device. When the audible and visual alarm sends out an audible and visual alarm signal, the relay supplies power to the gas solenoid valve and the exhaust fan. The gas solenoid valve automatically cuts off the gas supply in the gas equipment, and at the same time, the exhaust fan starts to exhaust air to the outside.

When the gas flux detector detects an abnormal change in the gas flux in the gas pipeline, and the gas detector detects that there is gas escape, but the value of the combustible gas content (LEL) detected by the combustible gas detector When it is greater than 20%, it indicates that there is a severe gas leakage. At this time, the main controller controls the operation of the sound and light alarm, the gas cut-off device and the communication alarm. In addition to performing sound and light alarms, automatically cutting off the gas supply and exhausting the outside, it can also directly use the The communication alarm dials 119 to call the police for help.

In daily use, the user can also realize human-computer interaction through the interaction module, such as manually inputting information into the main controller, obtaining operation information of the main controller, and the like.

The device provides a gas valve automatic detection and alarm device which adopts multiple detection devices for detection and can take different countermeasures according to different situations of gas leakage. While improving the detection accuracy, it also enhances the practicability of the device, and realizes the gas safety protection in daily household use.

The utility model still has multiple implementation modes, and all technical solutions formed by equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
