The main characteristics of liquefied petroleum gas liquefied gas use pneumatic valve method

liquefied gas pneumatic valve, also called door and is one of the most widely used pneumatic valve, it is popular, is due to open and close in the process of friction surface, more durable, opening, manufacturing easy, convenient maintenance, not only suitable for low voltage, and is suitable for high pressure. Below small make up to introduce the liquefied petroleum gas of pneumatic valve using method and main characteristics of liquefied petroleum gas.

the key features of liquefied petroleum gas, flammable and explosive. Than gasoline such as oil, natural gas has a greater risk of fire explosion accident. Reaches a certain concentration of gas in the air, and even in cold region, met during a static or metallic tiny spark, can quickly lead to combustion. Liquefied petroleum gas and air mixture concentration - - %, it will explode.
, gas liquid ratio of large volume, volatile: under atmospheric pressure, the liquid LPG gasification for - quickly - Times the volume of liquefied gas.
, liquid density is lighter than water. As oil floats on the surface of the water, about half of the proportion of water. Times one by one, so the liquefied petroleum gas, deposition in low-lying place extremely easily, cause burning explosion accident.
, large volume expansion coefficient. The volume expansion coefficient of liquefied petroleum gas (LPG) is about the same temperature, the volume of water expansion coefficient ~ times, with the increase of temperature, liquid volume will continue to expand, the gas pressure also increased, higher degrees Celsius temperature, volume expansion. ~。 %, pressure increase. ~。 MPa。
and low boiling point. Average boiling point under ℃, in our country, especially in the south, even the coldest temperature in winter conditions, can also be natural gas.
and low flash point. Lowest below ℃, the formation of volatile gas mixture combustion temperature is called flash point, flash point easily happened only a momentary flame combustion or flash, flash point is the forerunner of the fire.
, corrosive: liquefied petroleum gas in a corrosive, mainly small amounts of sulfide, have traces of corrosion of steel equipment, melt for rubber.
, can smell: liquefied petroleum gas, no special smell, in order to easy to detect leaks, ethyl mercaptan and other additives are added into the liquefied petroleum gas (LPG) and smelly.
, toxic and suffocating: liquefied petroleum gas (LPG) has a low toxicity, when more than % of liquefied petroleum gas concentration in the air, can make a person vomiting, feel headache; Reach a %, 2 minutes can make the person anesthesia, inhaled high concentrations of liquefied petroleum gas, suffocation death occurs.
