Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas detectors, in particular to combustible gas detector testing equipment. Background Art

[0002] A combustible gas detector is a detector that responds to the concentration of a single or multiple combustible gases. There are two types of combustible gas detectors: catalytic and infrared optical. Catalytic combustible gas detectors use the resistance change of refractory metal platinum wire after heating to measure the concentration of combustible gas. When combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire. The heat generated increases the temperature of the platinum wire, and the resistivity of the platinum wire changes. After the combustible gas detector is produced, a combustible gas detector test equipment is required;

[0003] A part of the traditional combustible gas detector test equipment places the combustible gas detector inside the detection device and injects combustible gas to test the combustible gas detector;

[0004] There are problems. Some traditional combustible gas detector test equipment has uneven contact of combustible gas detectors due to the fixed combustible gas spraying device, which makes the contact time of each combustible gas detector different, and the internal air cannot flow, making it impossible to quickly achieve the expected effect after the test. For this reason, we propose a combustible gas detector test equipment. Utility Model Content
