Gas leakage detection ring with self-protruding light change at natural gas pipeline interface

Abstract

The invention discloses a gas leakage detection ring with self-protruding light change at a natural gas pipeline interface, belongs to the field of natural gas. Through the arrangement of a detectionring body, when natural gas leakage occurs, a section type gas change layer generates expansive deformation, so that a self-extending rod extends out of the upper end of an outer fixed shell and thenis gradually bent, and a color change bent ball at the end of the self-extending rod is gradually close to the adjacent color change bent ball. On one hand, the protruding self-extending rod can playa role in reminding a user. On the other hand, extension suction blocks, close to each other, on the two color change bent balls adsorb each other, so that the extension suction blocks are loosened ina powder leakage hole or is adsorbed out of the powder leakage hole, and fluorescent powder can be leaked out of the powder leakage hole. Further, a user can be further reminded of natural gas leakage, so that the probability that the user finds leakage is remarkably increased, and potential safety hazards are effectively reduced.

Description

technical field [0001] The invention relates to the field of natural gas, in particular to a gas leakage detection ring with a self-protruding optical change at the interface of a natural gas pipeline. Background technique [0002] Natural gas is stored in underground porous rock formations, including oil field gas, gas field gas, coal bed methane, mud volcano gas and biologically generated gas, etc., and a small amount comes from coal seams. It is a high-quality fuel and chemical raw material. [0003] The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low molecular weight hydrocarbons and non-hydrocarbon gases. [0004] It is mainly composed of methane (85%) with small amounts of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). It is mainly used as a fuel, and is a...

Problems solved by technology

[0005] The natural gas pipeline interface is prone to aging after long-term use, and there is a possibility of air leakage. When the natural gas leakage is small, although the natural gas has an odor, the content is small and it will disperse in the air, making it difficult to Discovered in time, due to its flammability, there is a greater safety hazard
