In figure: 1, front retainer plate; 2, air intake opening cock plug; 3, air intake opening; 4, fixed mount; 5, rear demarcation form; 6, rear retainer plate; 7, marked gas; 8, gas outlet; 9, gas outlet cock plug; 10, cylindrical shell is demarcated; 11, front demarcation form.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The structure of a kind of infrared gas detector Demarcate Gas of the utility model device as shown in Figure 1, described Demarcate Gas application of installation is when infrared gas detector Demarcate Gas, replace the marked gas constantly injected, it comprises demarcates cylindrical shell 10 and is arranged at the air intake opening 3 demarcated on cylindrical shell 10, gas outlet 8, front demarcation form 11, rear demarcation form 5, front retainer plate 1, rear retainer plate 6, also comprises fixed mount 4, marked gas 7, air intake opening cock plug 2 and gas outlet cock plug 9.
Front demarcation form 11 is arranged on to be demarcated on front side of cylindrical shell 10, and fixes with front retainer plate 1.Rear demarcation form 5 is arranged on to be demarcated on rear side of cylindrical shell 10, and fixes with rear retainer plate 6.The material of front demarcation form 11 and rear demarcation form 5 is sapphire glass, can completely by probing light that red gas detector sends.
Demarcation cylindrical shell 10 can be fixed in the detection light path of gas detector by fixed mount 4.The Infrared of detector is arrived on the photosensitive receiving element of detector by front demarcation form 11, marked gas 7, rear demarcation form 5.
Demarcate on cylindrical shell 10 and have air intake opening 3 and gas outlet 8, when marked gas 7 injects from air intake opening 3, demarcating original air in cylindrical shell 10 can discharge completely from gas outlet 8, and making to demarcate in cylindrical shell 10 is marked gas 7 completely.When being marked gas 7 completely in demarcation cylindrical shell 10, blocking air intake opening 3 with air intake opening cock plug 2, blocking gas outlet 8 with gas outlet cock plug 9.
After demarcation cylindrical shell 10 injects marked gas 7, can first be arranged in the light path of the infrared gas detector instrument of having demarcated, test its gas concentration reading, if reading is on the low side, can to outward winding air intake opening cock plug 2 and gas outlet cock plug 9, to inject some gases higher than marked gas 7 concentration from air intake opening 3, make it reach demarcation concentration, block air intake opening 3 with air intake opening cock plug 2 again, block gas outlet 8 with gas outlet cock plug 9; If reading is higher, can outward winding air intake opening cock plug 2 and gas outlet cock plug 9, inject some air from air intake opening 3, make it reach demarcation concentration, then block air intake opening 3 with air intake opening cock plug 2, block air intake opening 8 with gas outlet cock plug 9.
