Description of drawings
The schematic diagram of a kind of embodiment of accompanying drawing 1 the utility model.
Embodiment
Below in conjunction with concrete real the drawings and specific embodiments, further specify the utility model.
The Household gas warner pick-up unit for detection of fuel gas alarm, comprises the calibrating gas case, gas analyzer, brassboard, fuel gas alarm control module.
Wherein: calibrating gas case tank wall arranges air intake opening, exhausr port.Calibrating gas case good seal adds the sealing silica gel strip between the door of test box and the frame, is connected with the silica gel sealing bar between air intake opening and the casing, guarantees that the interior gas of testing process raising middle flask does not leak.During detection, air intake opening connects external air source by gas piping, the air inlet electromagnetic valve of connecting on the gas piping, and calibrating gas case the inside is full of test gas.The calibrating gas case has been installed fan, is beneficial to gas uniform and mixes.For rapid mixing, in the standard testing case, a plurality of miniature stirring electric fans can be installed, force the interior gas of test box to carry out mixing circulation, make the interior gas of case within the extremely short time, reach even combined balance system.
Exhausr port connects outside by gas piping, the exhaust solenoid valve of connecting on the gas piping, and exhaust solenoid valve gas piping end can connect air exhauster, so that the test gas in the calibrating gas case is thoroughly emptying.
Air inlet electromagnetic valve is connected with exhaust solenoid valve with the fuel gas alarm control module and is connected.
Brassboard is arranged in the calibrating gas case, and the fuel gas alarm of pre-detection is placed on the brassboard, and is electrically connected with the fuel gas alarm control module; The fuel gas alarm control module connects gas analyzer, and the detection probe of gas analyzer is communicated with gas in the calibrating gas case by recycle gas line.The calibrating gas case is installed brassboard, is used for placing flammable gas alarm to be detected, and the punching of breadboard many places easily makes calibrating gas evenly diffuse to test box everywhere.Built-in power socket on the plate, in order to power supply is provided for fan and combustible gas probe, the external ground wire of supply socket can prevent electric spark.
The fuel gas alarm control module is connected with computing machine with time calibrator and is connected, and time calibrator is connected with computing machine, in order to carry out time calibration.Make the output signal of fuel gas alarm control module by Computer display, and by the software control fuel gas alarm control module of installing on the computing machine, and then control corresponding air inlet electromagnetic valve and exhaust solenoid valve.
Further, described gas analyzer is infrared gas analyzer.In the present embodiment, infrared gas analyzer is comprised of the infrared gas analyzer that can detect three kinds of gas with various.Infrared analyzer unit be used for to be measured hydrogen, methane, propane gas at the percentage composition of test box, and directly demonstration.Its optical system is comprised of light source, air chamber and detecting device three parts.Electrical system is comprised of prime amplifier, main amplifier, temperature control and power supply three parts.
Its principle of work is: continuous infrared radiation is modulated into the 6.25Hz chopped radiation to light source part and alternately (single tube is every half air chamber the analysis limit by air chamber and reference limit, the sealing of reference limit does not absorb ultrared high pure nitrogen), absorbed by detecting device at last.
The detecting device that this instrument adopts is cholic acid pyroelectricity detecting device, and when the analysis room passed into high pure nitrogen, then detecting device alternately equated with analysis limit infrared energy on the reference limit of reception, and the output signal of instrument is zero.When the analysis room passes into component to be measured, the reference signal that detecting device receives is constant, and analytic signal changes owing to the absorption of component to be measured in the analysis room, so just produce an output signal that is directly proportional with component to be measured, this small electric signal becomes and the proportional direct current signal of component concentration to be measured through impedance transformation, prime amplification, the main links such as (coarse adjustment, fine tuning), frequency-selecting, phase sensitive detection and filtering of amplifying by prime amplifier and main amplifier.
The below describes the fuel gas alarm pick-up unit course of work in detail:
Open the calibrating gas box cover, a plurality of gas leak detectors to be measured sequentially are positioned on the brassboard, connect successively power supply and the Signal plug of each alarm, the loam cake of then leaving behind, buckle well box fastener, opening power master switch.
Before test, give first electric preheating on the alarm to be measured, alarm to be measured is stabilized in normal operating conditions and detects.
