Gas leakage detection device for gas pipeline

Abstract

The invention discloses a gas leakage detection device for a gas pipeline, and belongs to the field of gas pipelines. According to the device, in the use process of the gas pipeline, when a sealing ring is aged and corroded to cause gas leakage, a liquid storage bag is damaged, so that an aqueous solution overflows, is adsorbed to the surface of an expansion balloon through a water guide rope, so that the expansion balloon expands; the storage bag is punctured through a spine, the sealing ring is repaired through the repairing liquid, the gas can still be sealed within a short time; air in the storage bag is extruded through the expansion balloon, and a rubber sealing piece is opened, so that a gas-permeable membrane and oxalic acid diester react with each other, energy after the reaction is transmitted to a fluorescent dye, the fluorescent dye emits fluorescence, external workers are prompted that the gas pipeline leaks and needs to be maintained in time, and the possibility that the workers are suffocated or exploded due to gas leakage is reduced.

Description

technical field [0001] The invention relates to the field of gas pipelines, in particular to a gas pipeline gas leakage detection device. Background technique [0002] The gas pipe has the characteristics of convenient installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation or gas resistance. The material of the surface soft protective layer is safer, easier to clean, and more beautiful. The service life of the stainless steel threaded metal hose is 8 years. In China's municipal pipe market, plastic pipes are developing steadily. PE gas pipes, PP-R gas pipes, and UPVC gas pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most eye-catching, and its application fields are also very important. extensive. [0003] At present, during the use of gas pipelines, the phenomenon of aging and corrosion of gas pipelines may occur after long-term...

AI Technical Summary

Problems solved by technology

[0003] At present, during the use of gas pipelines, the phenomenon of aging and corrosion of gas pipelines may occur after long-term use, resulting in gas leakage. When gas leakage is not found for a long time, the content of natural gas in the air will cause people Asphyxiation, when natural gas accumulates in a closed environment such as a house or tent, when it reaches a certain ratio, a powerful explosion will be triggered, which may level the entire house, or even damage adjacent buildings, causing huge losses
