Abstract
The utility model relates to a flammable gas automatic monitoring and discharging device, which can automatically monitor and discharge the flammable gas. A closed loop control system is composed of a gas sensor, a controller and a fanner. When the concentration of the flammable gas in the monitoring space reaches a definite value, the signal is transmitted to the controller by the sensor, and the controller can start the fanner; when the gas concentration is decreased to a definite value, the signal is transmitted to the controller again by the sensor, and the fanner can be stopped by the controller. The purpose of automatically monitoring and discharging the flammable gas can be obtained.
Description
The utility model belongs to household electrical appliance technical field
Along with development and national economy, liquefied petroleum gas (LPG) and coal gas is widespread usage in the family.Yet because people's misoperation and managing failures often cause gas to leak.Therefore the gas burst accident happens occasionally.In order to address this problem, people have made various warning devices.These warning devices begin to report to the police when inflammable gas reaches finite concentration.Reminds people is noted or is taked corresponding measure.Sometimes since people can not in time take measures or because of the people not at the scene, take place so accident is just unavoidable.
The purpose of this utility model provides a kind of inflammable gas and monitors tapping equipment automatically.
As long as inflammable gas is monitored tapping equipment automatically is installed on the room that is faced survey, as combustible gas leakage, after inflammable gas reached finite concentration, sensor sent signal, by controller, ventilation equipment was started, and dense higher inflammable gas is discharged.Thereby reduced the concentration of inflammable gas, avoided the generation of accident.When combustable gas concentration during less than certain value, sensor is transferred to controller with signal, and ventilation equipment cut out automatically.
This monitoring tapping equipment is formed closed-loop control system (seeing figure one) by gas sensor controller and ventilation equipment
Sensor is made up of gas sensor and corresponding power supply.
Controller is made up of electronic component, can be discrete component or integrated package, is connected with ventilation equipment with sensor respectively with lead.
The exhaust fan that ventilation equipment are special-purpose, also culinary smoke exhaust, or other ventilation equipment.
This device can be contained in sensor and controller in the housing of arbitrary shape, also sensor and controller can be made in the ventilated enclosure.Also can with sensor and controller be done shell respectively and ventilation blower is installed in suitable place respectively.
The concentration of sensor monitors inflammable gas, and signal is transferred to controller, the work of control ventilation equipment.
Because of inflammable gas lta usually, so the sensor of this machine and controller should be installed near outside the ceiling.
Due to the Yin Ben monitoring sensor performance that tapping equipment adopted, in 10 minutes after energising unstable properties (being initial stabilized time) after 10 minutes this machine work just stablized.
The utility model not only is used for family, and the departments such as chemical industry, light industry, electronics, metallurgy that also can be applicable to monitor discharging to inflammable gas.
Claims (1)
1, inflammable gas is monitored tapping equipment automatically, it is characterized in that total system forms closed-loop control system by sensor, controller and ventilation equipment; This device can be contained in sensor and controller in the housing of any form, also sensor and controller can be made in the ventilation blower housing, also sensor and controller can be done shell respectively.
