Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as Figure 1-Figure 2 As shown, a device for flame sensor performance detection includes a gas transmission unit, a flame sensor test unit and a central control unit, wherein

[0034] The gas transmission unit includes a mixed standard gas device, a first gas flow meter 1, a first one-way valve 2, a first connecting pipe 3 and a second connecting pipe 301, and the gas outlet end of the mixed standard gas device passes through the first connecting pipe 3 and the second connecting pipe 301. The inlet end of a one-way valve 2 is connected, and the middle section of the first connecting pipe 3 is equipped with a first gas flowmeter 1. The first gas flowmeter 1 is used to control the flow rate of the charged gas. The end is fixedly connected with the ignition device in the flame sensor test unit through the second connecting pipe 301;

Abstract

The present invention relates to the technical field of mining devices, in particular to a device and a detection method for flame sensor performance detection, including a gas transmission unit, a flame sensor testing unit and a central control unit, wherein the gas transmission unit includes a mixed standard gas device, a second A gas flow meter, a first one-way valve, a first connecting pipe and a second connecting pipe, the flame sensor test unit includes an explosion-proof chamber, a rail car assembly, a flame sensor, an ignition device and a tester, and the central control unit includes a PLC, and the PLC respectively It is electrically connected with the first gas flow meter, spark discharge electrode, rail car components and distance measuring sensor, PLC is used to control the gas transmission, gas flow and gas concentration of the gas transmission unit, and is used to control the flame sensor test unit The ignition and position of the railcar components are controlled. It has the advantage of being widely used in the test and detection of the performance of red and ultraviolet flame sensors.

Description

technical field [0001] The invention relates to the technical field of mine devices, in particular to a device and a detection method for performance detection of a flame sensor. Background technique [0002] Article 186 of the "Coal Mine Safety Regulations" mines that exploit coal seams with coal dust explosion hazards must have measures to prevent and isolate coal dust explosions; Explosion-proof facilities shall be installed at the driving face of coal roadways and semi-coal and rock roadways in mines with explosion hazards. According to the above requirements, the state has formulated the coal industry standards "Automatic Explosion-proof Devices for Coal Mine" and "Automatic Dust Spraying Explosion Suppression Devices for Gas Pipeline Transportation". [0003] The flame sensor is a core component of the automatic explosion suppression device. The current situation of flame sensor detection is: 1. Requirements for the triggering conditions of the sensitivity of the ultr...
