Fig. 2 is the structural representation of base.

Fig. 3 is the A-A cut-open view of Fig. 2.

Embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Referring to Fig. 1, Fig. 2 and Fig. 3, on the outer wall of columniform organic glass body 1 delineation scale 6, scale from top to bottom from " 0 " ml to " 800 " ml, precision is 2ml;

Process a fluid injection duct 8 at the center of the discoidal base made from organic glass 7, and at the bottom plug 4 that place fitted seal circle and stainless steel are made that enters in fluid injection duct, the annulus 10 that connects an organic glass at the edge of base 7 bottoms, one side on base 7 vertically is provided with an admission piece 2, and the another side on base 7 vertically is provided with a fluid mouth 3; The height of admission piece 2 is higher than the height of fluid mouth 3.

The lower end of body 1 is vertically connected on the base 7 that discoidal organic glass makes, and fluid injection duct 8, admission piece 2 and fluid mouth 3 is communicated with body 1, gland bonnet 9 is bonded in the upper end of body 1, with hanger 5 be bonded in gland bonnet 9 above;

Working fluid 11 (water or saturated saline solution) is injected in the body 1, promptly constitute fire damp desorption rate analyzer described in the utility model.Whole analyzer is placed in the casing that has foam spacer and carries.

Embodiment one: before the use, this analyzer is inverted, bottom plug 4 turns round and round out, by the fluid injection duct 8 at the base 7 centers working fluid 11 of in body 1, annotating, this routine working fluid is a water, fill with the enter place of back, then, again this analyzer is reversed with O-ring seal and bottom plug 4 shutoff fluid injection ducts, tie up on the hanger 5 with tightrope, this analyzer is overhang in the air, and at this moment, the fluid mouth 3 and the admission piece 2 that are located at above the base 7 have a little amount of work liquid to flow out, make the top in the body 1 form negative pressure, working fluid in the body no longer continues to flow out from fluid mouth 3 and admission piece 2 under the atmospheric pressure effect, thereby makes the operating fluid level in the body keep stable.Before beginning to measure, the operating fluid level in the body 1 is in " 0 " scale or " 0 " below the scale, and admission piece 2 is connected with the coal sample tube valve that fresh coal sample is housed, and fluid mouth 3 is in free state.Before opening coal sample tube valve, read scale as initial value, open behind the valve per minute and do not read when a scale has bubble to gush in reading 30min data or 30min and stop, per minute desorption of mash gas amount that measuring gained is the fire damp desorption rate value of fresh coal sample.
