Abstract
The invention provides a fuel gas alarm which mainly comprises an alarming detector, an alarming controller and a transmission system, the alarming controller is connected with a fuel gas intake tube by an electromagnetic valve, and the alarming detector consists of a concentration detector and a high-sensitive pressure detector, the probe of the high-sensitive pressure detector is arranged in the fuel gas intake tube. The pressure in the tube can be detected when the fuel gas intake tube is opened or closed, and the pressure change signal caused by regulating a fuel gas valve manually can be ignored. The probe of the concentration detector is arranged in air for detecting the concentration of fuel gas in the environment. When one of the two detectors is abnormal, first-grade alarm is sounded and displayed on the controller, and when the two detectors are abnormal simultaneously, second-grade alarm is sounded and the fuel gas intake tube is closed automatically. The beneficial effects of the fuel gas alarm are as follows: the high-sensitive pressure detector is applied to the fuel gas alarm, the danger of forgetting to close the fuel gas owning to busyness can be reduced, and the alarm is convenient and saves the using amount of the fuel gas.
Description
Technical field
The present invention relates to a kind of alarm, especially a kind of fuel gas alarm.
Background technology
So-called gas-cooker is meant the kitchen utensils that carry out straight fire heating with gaseous fuels such as liquefied petroleum gas (LPG), artificial coal gas, rock gases.Gas-cooker is stone or metal plate for standing a stove on as a precaution against fire again, and its popular degree is known to all, but is difficult to see a current notion.Just like firewood stove, kerosene stove, coal dust ball stove or the like.Say that by source of the gas gas-cooker mainly is divided into liquefied gas cooker, gas range, natural gas range.Say by the kitchen range eye, be divided into single kitchen range, two kitchen range and multi-hole kitchen range.
The kind of combustion gas is a lot, mainly contains rock gas, manufactured gas, manufactured fuel gas, liquefied petroleum gas (LPG) and biogas.Rock gas claims casing-head gas, petroleum gas, oil field gas again.Its chemical composition and physicochemical property thereof vary in different localities, and principal ingredient is a methane, and methane content accounts for more than 95%, also contain a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, sulfuretted hydrogen etc.Natural gas leaking also spreads in indoorly, makes indoor occupant and poisons because of big cerebral anoxia; Indoor occupant is because of ignorant, and phones with mobile telephone or Switching Power Supply etc. indoor connecing, and produces spark initiation fire or blast, causes the people's life, property loss.The alarm installation site: in 1.5 meters scopes of source of the gas radius, the well-ventilated place: (1) liquefied gas is heavier than air, and is installed in about 0.3 meter apart from ground.(2) rock gas, town gas, carbon monoxide geometric ratio air are light, are installed in apart from about 0.3 meter of ceiling.(3) position of alarm can not be installed: air is difficult for the position of circulation in corner, the cabinet etc.; The easy position of directly being smoked by oil smoke etc.Yet domestic general fuel gas alarm stability is not fine now.
Summary of the invention
At the problems referred to above, the invention provides a kind of fuel gas alarm.
A kind of fuel gas alarm, mainly by alarm detector, alarm controller and transmission system are formed, it is characterized in that alarm controller is connected with gas inlet pipe by solenoid valve, alarm detector is made up of concentration detector and highly sensitive pressure detector, the probe of highly sensitive pressure detector places in the gas inlet pipe, pressure in can detector tube when opening and closing gas inlet pipe, the pressure change signal that the manual adjustments burnt gas valve causes will be left in the basket and disregard, the probe of concentration detector places air, be used for the testing environment gas concentration, two one of them appearance of detector will be sounded one-level unusually and report to the police, and on controller the display abnormality reason, second-level alarm and automatic self-closing gas draft tube appear will sounding unusually in two detectors simultaneously.
Remarkable result of the present invention is that highly sensitive pressure detector is applied in the fuel gas alarm that daily life uses, reduce people and forget the danger of closing combustion gas because of things is busy, if long-time no one's control can the automatic self-closing gas import, convenient and economize on tolerance, reduce dangerous the generation.
Description of drawings
Accompanying drawing is the fuel gas alarm synoptic diagram
Wherein: 1, gas inlet pipe; 2, solenoid valve; 3, highly sensitive pressure detector; 4, alarm controller; 5, the concentration detector.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: alarm controller 4 is connected with gas inlet pipe 1 by solenoid valve 2, alarm detector is made up of concentration detector 5 and highly sensitive pressure detector 3, the probe of highly sensitive pressure detector 3 places in the gas inlet pipe 1, pressure in can detector tube when opening and closing gas inlet pipe 1, the pressure change signal that the manual adjustments burnt gas valve causes will be left in the basket and disregard, the probe of concentration detector 5 places air, be used for the testing environment gas concentration, two one of them appearance of detector will be sounded one-level unusually and report to the police, and on alarm controller 4 the display abnormality reason, two detectors second-level alarm occurs will sounding unusually and simultaneously by solenoid valve 2 automatic self-closing gas draft tube 1.
The invention has the beneficial effects as follows highly sensitive pressure detector is applied to the fuel gas alarm that daily life is used In, reduce people and forget the danger of closing combustion gas because things is busy, if long-time no one's control can be automatic Close fuel gas inlet, convenient and economize on tolerance, also can reduce and cause unnecessary life, property to decrease Lose, relatively be fit to family and hotel.
