Embodiment 1

[0024] see figure 1 , in an embodiment of the present invention, a safety gas metering device with an over-temperature cut-off function, comprising:

[0025] The temperature detection unit 100 is used to detect the temperature of the gas environment at the user end, and when the temperature of the gas environment exceeds the limit, a gas valve switch signal is sent to the signal processing unit 200;

[0026] The signal processing unit 200 is used to receive the gas valve switch signal fed back by the temperature detection unit 100 when the gas ambient temperature exceeds the limit, and perform calculation and processing according to the externally detected data, and control the gas valve on and off and data reporting;

[0027] The emergency control unit 300 communicates with the signal processing unit 200 and is used to control the on and off of the gas valve; and

[0028] The alarm unit 400 communicates with the signal processing unit 200 and is used to report to the data ce...

Embodiment 2

[0030] see figure 1 , the difference between this embodiment and embodiment 1 is:

[0031] In this embodiment, the temperature detection unit 100 includes a temperature control switch, and the way to obtain the abnormal temperature of the user's gas environment is through the temperature control switch. When the temperature of the gas environment exceeds the limit, the gas valve switch signal is directly sent to the signal In the processing unit 200, the signal processing unit 200 sends a gas valve cut-off command to realize the emergency cut-off function.

[0032] In this embodiment, the signal processing unit 200 includes an electronic metering device, and the gas valve is set in the electronic metering device, and the abnormal temperature signal of the gas environment at the user end is integrated with the electronic metering device. On the premise of ensuring normal metering Realize the cut-off and alarm for the abnormal temperature of the gas environment at the user end....

Abstract

The invention relates to a fuel gas metering device, in particular to a safe fuel gas metering device with an over-temperature cut-off function. The safe fuel gas metering device comprises a temperature detection unit and a signal processing unit, wherein temperature detection unit is used for detecting the used gas environment temperature of a user side, when a phenomena the the used gas environment temperature exceeds the limit occurs, a gas valve switch signal is given to the signal processing unit; the signal processing unit is used for receiving the fuel gas gas valve switch signal, whichis fed back by the temperature detection unit, of the over-limit used gas environment temperature, performing calculating treatment according to external detection data, controlling the gas valve tobe opened and closed and reporting the data; and the safe fuel gas metering device further comprises an emergency control unit and an alarm unit. According to the safe fuel gas metering device with the over-temperature cut-off function, when a user side occurs accidents such as a fire disaster and the like, the fuel gas electronic metering device can detect the condition of the external environment temperature according to the temperature detection unit, and when the temperature exceeds a set limit value, fuel gas supply is cut off through a gas valve in the electronic metering device, so thataccident expansion and secondary injury to personnel are avoided.

Description

technical field [0001] The invention relates to a gas metering device, in particular to a safe gas metering device with an over-temperature cut-off function. Background technique [0002] With the continuous improvement of automation instrumentation technology, the gas metering instruments currently used by users have achieved basic automation. The gas metering device can detect the gas consumption, and control the on and off of the gas meter through the cut-off valve in the meter. With the upgrading and updating of communication technology, an Internet of Things smart metering system with the Internet and big data as the core has emerged. [0003] At present, there is no gas metering device with an over-temperature cut-off function, which is likely to cause accident expansion and secondary injury to personnel. Therefore, in view of the above status quo, it is urgent to develop a safe gas metering device with an over-temperature cut-off function to overcome the shortcomings...
