Description
Technical field
The utility model belongs to detector field, particularly relates to a kind of self-priming gas detector housing.
Background technology
Gas detector, combustible gas probe, it is that it is generally divided into catalytic type combustible gas probe and semiconductor combustible gas probe to detector single or many combustible gases concentration-response.
Catalytic type combustible gas probe is to utilize the resistance variations after the heating of refractory metal platinum filament to measure combustable gas concentration, when inflammable gas enters detector, on platinum filament surface, cause oxidation reaction (flameless burning), the heat of its generation raises the temperature of platinum filament, and the resistivity of platinum filament just changes; Semiconductor combustible gas probe will be with the higher gas sensory element of sensitivity, and it runs into inflammable gas in working order time, and semiconductor resistor declines, and drop-out value and combustable gas concentration have corresponding relation.
In the combustion gas bulk detector of semiconductor-type, gas sensory element senses is after inflammable gas, resistance declines, the measurement of resistance value is measured by resistance measuring instrument, then sends to processor, and processor is according to transient resistance, calculate combustable gas concentration value, and show on display, allow staff check, hummer is also set sometimes and reports to the police.
The housing of existing gas detector is generally adopted made of plastic, when staff carries detector inspection, or while being fixed on the easy leak point of combustion gas, if there is electrical appliance wires, damage, produce electric spark or electric arc, likely combustible gas is lighted, not only burn out gas detector, also can hurt staff, or the electric equipment of periphery, blast tube, causes great accident.Now also have and use insulation fire prevention housing, because need moment to cut off, the air admission hole of setting is very little, and patrol personnel need to check in environment at need, stand and for a long time just can have result of detection, uses very inconveniently, has wasted a large amount of time.
Utility model content
