Problems solved by technology

[0003] Natural gas is usually transported through pipelines. After a long period of use, gas leakage may easily occur at the interface of natural gas pipelines due to aging. When natural gas leaks at a slow rate, it is difficult to be found, but due to its flammability, there are large security risks

Abstract

The invention discloses a leakage reminding barrel for a natural gas pipeline joint, and belongs to the technical field of natural gas. Through the arrangement of an outer sleeve and related components, when the pipeline joint leaks, leaked natural gas can enable an elastic film to protrude upwards, so that a switch button is automatically triggered to turn on a power supply, an alarm device can be started to give an alarm, related workers can know the occurrence of gas leakage in time, thereby eliminating potential safety hazards and greatly improving the safety; meanwhile, a conductive rod can be electrified to harden a state changed filling body and shape an elastic tubular bag, so that the sealing effect of the elastic tubular bag can be greatly improved, and the amount of natural gas leaking to the outside of the outer sleeve is remarkably reduced; by arranging a shading tube, the elastic film protrudes upwards, meanwhile, a part of the light-reflecting reminding rod can be automatically exposed out of a shading tube, secondary reminding is given out, the reminding function is enhanced, and practicability is greatly improved.

Description

Technical field [0001] The present invention relates to the field of natural gas technologies, and more particularly to a leakage alert cartridge for a natural gas pipeline connection. Background technique [0002] Natural gas is contained in the underground porous rock formation, including oilfield gas, gas field gas, coalbed methane, mud gas mountain gas and biological production, and a small amount of coal seam. It is a high quality fuel and chemical raw material. The main use of natural gas is fuel, which can make carbon black, chemicals, and liquefied petroleum gas, produced by natural gas, butane is an important raw material in modern industries. Natural gas is mainly composed of gaseous low molecular hydrocarbons and non-non-non-hydrocarbon gases. [0003] Natural gas is usually delivered through the pipeline, and the natural gas pipeline interface, after a long period of use, it is easy to leak due to aging, when the gas leakage speed is slow, it is difficult to discover,...
