Description

Technical Field

[0001] The utility model relates to the technical field of gas detectors, in particular to an explosion-proof gas detector. Background Art

[0002] Explosion-proof gas detectors are used in explosion-proof places. They are gas detection equipment installed in explosive hazardous environments. They convert the on-site combustible gas concentration into digital signals and transmit them to the gas alarm controller located in the safe area. They can continuously detect the content of the measured gas in the air within the lower explosion limit for a long time. They can be widely used in various industries such as gas, petrochemical, metallurgy, steel, coking, and electricity where combustible or toxic gases exist. They are ideal monitoring instruments to ensure property and personal safety.

At the same time, most of the existing gas detectors are fixed with bolts, which requires multiple bolts to be rotated in sequence for each installation and disassembly. Disassembly is inconvenient, which brings inconvenience to future operators for maintenance and replacement. Utility Model Content
