瓦斯簡介
瓦斯為生活帶來便利但亦能輕易奪取人類的生命,由於民生之必需,人類的生活必須仰賴瓦斯,瓦斯雖然方便,但若不當使用或因一時疏忽,都將造成無法彌補的遺憾。
瓦斯洩漏的危險性 :
● 液化石油氣氣化後之重量約為空氣之1.5倍,因此漏氣時,易滯留在低處或角落。空氣中混入1.8%至9.5%的液化石油氣,遇到火源便會產生燃燒或爆炸。
● 天然氣比重較空氣輕,漏氣時,易往上飄散。空氣中之 天然氣含量達5%至15%之間,遇到火源即會引起燃燒或爆炸。
瓦斯的來源
瓦斯是一般對氣體燃料的通稱,事實上,目前臺灣地區瓦斯的主要來源係分為液化石油氣與天然氣二大類。
一 、 液化石油氣
● 液化石油氣由原油煉製或天然氣處理過程中所析出的丙烷與丁烷混合而成,在常溫常壓下為氣體,經加壓或冷卻即可液化,通常是加壓裝入鋼瓶中供用戶使用,故又稱之為液化瓦斯或桶裝瓦斯。
二 、 天然氣
● 天然氣俗稱天然瓦斯,由瓦斯公司敷設管線直接供應用戶使用,故又稱之為導管瓦斯或自來瓦斯。
● 天然瓦斯係古生物遺骸長期沈積地下,經慢慢轉化及變質裂解而產生之氣態碳氫化合物,其主要成份為甲烷,並含有少量之乙烷、丙烷、丁烷等碳氫化合物及少量之不燃性氣體。
如何偵測瓦斯外洩

Gas
The gas is a life more convenient but also can easilycapture the human life, the livelihood of the people required, human life must depend on the gas, gas,although convenient, but if the improper use or due tonegligence, will cause irreparable regret.
Hazardous gas leakage:
The weight of the liquefied petroleum gas after gasification is about 1.5 times the air leakage, therefore,to stay in place or corner. Liquefied petroleum gas mixed with 1.8% to 9.5% in air, meet the fire will producecombustion or explosion.
● gas lighter air light, air leakage, easy to drift. Gascontent in the air of between 5% to 15%, encountered thefire will burn and explode.
Gas source
The gas is generally on the fuel gas known as, in fact, themain source of Taiwan area gas lines are divided intoliquefied petroleum gas and natural gas two categories.
A, liquefied petroleum gas
● liquefied petroleum gas precipitated from crude oil or natural gas treatment process of propane and butane and into, is a gas at room temperature and atmospheric pressure, the pressure or cooling can be liquefied,usually pressure for use by the user into the cylinder, so it is also called a liquefied gas or bottled gas.
Two, natural gas
The natural gas or natural gas, the gas pipeline installation directly supply the users, so it is also called acatheter gas or water gas.
The natural gas Department of the ancient biological remains long-term deposited underground, gaseous hydrocarbons generated by slowly transformed and metamorphic cleavage, its main composition is methane,ethane, propane, and contains a small amount of butane,hydrocarbon compounds and a small amount of non flammable gas.
How to detect a gas leak
The gas detector design company, portable design, easy to use, the original Japanese imports of the sensing element, keen on trace gas detection, can instantly send high decibel alarm sound, high stability, natural gas, the gas liquid leakage detection measure in 10 seconds, to remind the user real-time processing is discouraged oralienation of danger.
This product has the advantages of
■ Japan imported high precision sensor, short reaction time
Installation of the battery can be used - boot, without special adjustments. The default automatic shutdown ofpower saving
■ handheld design
Fixed type measurement need to install multiple detectorsand installation locations. Handheld design can greatly reduce the installation cost and can be in any place tomeasure real time measurement.
■ 5 segment LED display the current time range, lowpower tips
■ each boot will perform automatic correction (please in clean air boot)
■ sensor located 18 inches elastic snake at the front end of the pipe, can quickly find the gas leakage location, but also the sensing hose into the area of uncertaintymeasuring whether there is explosive gas
■ can instantly send high decibel alarm. Can be directlyor through headphones to listen
