The utility model discloses a theory of operation and use flow:

the principle of the detection part of the combustible gas detector is that a sensor of the detector adopts a detection element, a fixed resistor and a zero-setting potentiometer to form a detection bridge circuit. The bridge circuit takes platinum wire as a carrier catalytic element, the temperature of the platinum wire rises to the working temperature after being electrified, and air reaches the surface of the element in a natural diffusion mode or other modes. When the air contains no combustible gas, the bridge circuit output is zero, and when the air contains combustible gas and is diffused on the detection element, due to the catalytic action, flameless combustion is generated, so that the temperature of the detection element is raised, the resistance of the platinum wire is increased, the bridge circuit is out of balance, and a voltage signal is output, the voltage is in direct proportion to the concentration of the combustible gas, and the concentration of the combustible gas is displayed through a liquid display after the signal is amplified and subjected to analog-to-digital conversion.

The detection part is based on the principle that when the concentration of the detected combustible gas exceeds a limit value, the amplified bridge circuit output voltage and the circuit detection set voltage output a group of square wave signals through the voltage comparator, the square wave generator outputs a group of square wave signals to control the sound and light detection circuit, the buzzer generates continuous sound, the light emitting diode flashes and sends out detection signals. According to the principle of the combustible gas detector, if electromagnetic interference occurs, the detected signal is influenced, and data deviation occurs; if collision and vibration occur, the equipment is broken, and the detection fails; if the environment is excessively humid or water enters the equipment, the combustible gas detector can be short-circuited or the resistance value of the line is changed, so that the fault occurs.

Indication lamp description:

1, operation indication: the detector is powered on, the green indicator light flickers, and the detector enters a preheating state. After preheating for about three minutes, the green indicator lamp is normally on, and the detector enters a monitoring working state after the preheating process is finished.

2, fault indication: when the yellow fault lamp is on, the detector is indicated to be in fault, the detection alarm function is lost, and the use is stopped.

And 3, alarm indication: when the red alarm lamp is on, the gas concentration is over the alarm point, and the buzzer sounds; when the gas concentration is lower than the alarm point, the alarm lamp is turned off, and the buzzer does not sound.

The mounting base plate 300 is mounted on a wall surface and used for fixing a combustible gas detector, the mounting base plate 300 can be used for mounting various combustible gas detectors with different sizes and can be fixed on the wall surface for a long time, the adjusting mechanism 310 is used for adjusting the position of the mounting table 330 according to the size of the combustible gas detector, the adjusting block 312 is screwed, the studs 311 positioned on two sides of the adjusting block 312 move, the studs 311 move to drive the mounting table 330 to move, the sliding block 331 on the mounting table 330 slides with the sliding chute 301, at the moment, the sleeve 321 on the supporting mechanism 320 slides with the sliding column 322, the sleeve 321 extrudes the sliding column 322, after the appropriate position is adjusted, the combustible gas detector is taken up to align the buckle mechanism 210 on the mounting plate 200 with the mounting table 330 to press down, the buckle mechanism 210 can be extruded to rotate on the rotating shaft, when the clamping groove position on the mounting table 330 is reached, the buckle mechanism 210 can rebound to the original position under the action of the spring 213, the installation to the device that just realizes this moment, when needs demolish the change to the device, press unlock button 212, unlock button 212 can extrude buckle 211, and buckle 211 rotates in the pivot, just can outwards extract the device this moment, accomplishes the dismantlement.
