Abstract
A natural gas leakage detecting and alarming device comprises an alarming device (4), an infrared ray gas analyzer (1), a temperature sensor (2), and a controller (3). The infrared ray gas analyzer (1) is electrically connected with the temperature sensor (2). The temperature sensor (2) is electrically connected with the controller (3). The controller (3) is electrically connected with the alarming device (4). The natural gas leakage detecting and alarming device is not easy to have false alarms and can give alarms more accurately.
Description
Technical field
The utility model natural gas leaking detection technique field specifically relates to a kind of natural gas leaking detection alarm device.
Background technology
Rock gas is fuel commonly used in the at home life, made things convenient for people's life, but simultaneously because leaking the accident that causes, pipe natural gas brought huge threat to people's life and property, in order to take precautions against the generation of this type of accident, more existing natural gas leaking alarms are sold on the market, but there is following shortcoming in existing natural gas leaking alarm: as long as described natural gas leaking alarm has gas or smog to enter, will report to the police, produce wrong report easily and make people's false alarm or nervous, if often report by mistake, can affect normal life or make the people lose faith in alerting signal and new hidden danger occurs.
The utility model content
Technical problem to be solved in the utility model is, a kind of natural gas leaking detection alarm device that is not easy to occur reporting by mistake and can more accurate warning is provided.
Technical solution of the present utility model is, a kind of natural gas leaking detection alarm device with following structure is provided, it comprises warning device, it also comprises infrared ray gas analyzer, temperature sensor and controller, described infrared ray gas analyzer and temperature sensor, described temperature sensor is electrically connected with controller, described controller be electrically connected with warning device.After adopting above structure, natural gas leaking detection alarm device of the present utility model compared with prior art has the following advantages:
Natural gas leaking detection alarm device of the present utility model also comprises infrared ray gas analyzer, temperature sensor and controller, after rock gas enters infrared ray gas analyzer, based on the CH in the rock gas
4And NH
3Constituent concentration is different, the radiation energy that absorbs is also different, remaining radiation energy is so that the temperature in the infrared ray gas analyzer raises different, temperature variation in the infrared ray gas analyzer is connected to controller by temperature sensor, controller sends signal to the warning device sound that gives the alarm, because infrared ray gas analyzer is based on the constituent concentration of analyzing in the rock gas, controller sends alerting signal after reaching certain value based on the constituent concentration in the rock gas, so be not easy the phenomenon that occurs reporting by mistake, can more accurate warning.
As improvement, the gas access of described infrared ray gas analyzer also is connected with the hydraucone towards the natural gas line valve, hydraucone can play the effect of gathering when natural gas leaking, make infrared ray gas analyzer detect natural gas leaking as early as possible and in time start warning device and report to the police.
As preferably, described hydraucone is connected with the gas access one, connects more firmly, and hydraucone and junction, gas access Leakage Gas can not occur.
As preferably, described temperature sensor is located in the infrared ray gas analyzer, and is sensitiveer for the temperature variation in the infrared ray gas analyzer.
Description of drawings
Shown in Figure 1 is the structural representation of the utility model natural gas leaking detection alarm device.
Shown in the figure: 1, infrared ray gas analyzer, 1.1, the gas access, 2, temperature sensor, 3, controller, 4, warning device, 5, hydraucone.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1, the utility model natural gas leaking detection alarm device, it comprises warning device 4, it also comprises infrared ray gas analyzer 1, temperature sensor 2 and controller 3, described infrared ray gas analyzer 1 and temperature sensor 2, described temperature sensor 2 is electrically connected with controller 3, and described controller is electrically connected with warning device 4 with 3.
The gas access 1.1 of described infrared ray gas analyzer 1 also is connected with the hydraucone 5 towards the natural gas line valve.
Described hydraucone 5 is connected with gas access 1.1 one.
Described temperature sensor 2 is located in the infrared ray gas analyzer 1.
In the present embodiment, described infrared ray gas analyzer 1 adopts IRME-G type infrared ray gas analyzer, can be for detection of the CH in the rock gas
4And NH
3Concentration; Described temperature sensor 2 adopts STT-S series of temperatures sensor.
