Description

Gas leakage detection ring capable of automatically changing light from convex at joint of natural gas pipeline

Technical Field

The invention relates to the field of natural gas, in particular to a self-convex light-changing air leakage detection ring at a natural gas pipeline joint.

Background

Natural gas is trapped in underground porous rock formations, including oil field gas, gas field gas, coal bed gas, mud volcanic gas, biogenic gas, and the like, and a small amount of natural gas is also released from the coal bed. It is a high-quality fuel and chemical raw material.

The natural gas is mainly used as fuel, can be used for producing carbon black, chemicals and liquefied petroleum gas, and the propane and butane produced by the natural gas are important raw materials of modern industry. Natural gas is composed mainly of gaseous low molecular hydrocarbons mixed with non-hydrocarbon gases.

Mainly composed of methane (85%) and small amounts of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). The catalyst is mainly used as fuel and also used as raw materials for producing chemical compounds such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuel, hydrogenated oil, methanol, nitric acid, synthesis gas, vinyl chloride and the like. Natural gas is compressed into liquids for storage and transportation. Coal miners, nitric acid producers, power plant workers, organic chemical synthesis, gas users, petroleum refiners, and the like have an opportunity to contact the product. Mainly enters human body through respiratory tract. Belongs to pure asphyxia gas. Hypoxia is caused by air replacement when the concentration is high, so that the respiration is short and the consciousness is lost; the serious patient may die due to hypoxemia suffocation. High pressure natural gas can cause frostbite. Incomplete combustion can produce carbon monoxide.

The natural gas pipeline kneck, after long-time the use, the easy ageing phenomenon that takes place, there is the possibility of gas leakage, and natural gas leaks when the leakage quantity is less, though there is the peculiar smell in the natural gas, but the content is less and its can take place the dispersion in the air, leads to hardly in time discovering, because its inflammability, has great potential safety hazard.
