Abstract
The utility model relates to a fire damp check out test set specifically is a gas sample thief with watertight fittings, including gas sample thief (1), waterproof unit (3) are connected in leather hose end (2) of gas sample thief (1), waterproof unit (3) are including one cylindrical barrel (4), the both ends difference seal installation end cover (5) of cylindrical barrel (4), leather hose end (2) of gas sample thief (1) are connected to an end cover, and drilling leather hose (7) is connected to another end cover, allochroic silica gel (6) have been put in the cylindrical barrel. The utility model relates to a rationally, it has stopped the loss that gas inspection instrument results in because of intaking basically to install watertight fittings additional on the gas sample thief to haplopore gas density's measurement accuracy has been improved.
Description
Technical field
The utility model relates to fire damp checkout equipment, is specially a kind of gas sampler with water-tight device.
Background technology
Along with the continuous extension of underground coal mine face, gas bearing capacity is increasing, for solving gas problem, drawing out methane of existing underground construction is holed along with increasing, time at every turn by gas samplers sample pumping drillings mash gas concentration, cause directly connects boring with leather hose, during collection be difficult to find boring in whether have water, as in hole once there be water, be pumped in gas detection apparatus, the as easy as rolling off a log damage causing instrument, causes unnecessary instrument loss.
Summary of the invention
The purpose of this utility model is to provide a kind of gas sampler with water-tight device, for well protecting gas detection instrument.
The utility model adopts following technical scheme to realize:
A kind of gas sampler with water-tight device, comprise gas sampler, the leather hose termination of described gas sampler connects waterproof unit, described waterproof unit comprises a cylindrical tube, the two ends of described cylindrical tube seal installation end cap respectively, one end cap connects the leather hose termination of gas sampler, and another end cap connects boring leather hose; Discolour silica gel is placed with in described cylindrical tube.
During use, the A point of gas sampler connects portable gas explosion somascope, and B point connects firedamp taking-out discharging drilling gaging hole mouth.Once the color having water to be inhaled into discolour silica gel in boring can be changing into pink immediately, be very easy to find gas sampler by the change of color and whether suck moisture, soon improve the accuracy rate of extraction data, also avoid gas detection apparatus and cause because sucking moisture damaging.
The utility model is reasonable in design, gas sampler installs additional water-tight device and has substantially stopped the loss that gas detection instrument causes because of water inlet, and improve the certainty of measurement of single hole gas density.
Accompanying drawing explanation
Fig. 1 represents structural representation of the present utility model.
In figure, 1-gas sampler, 2-leather hose termination, 3-waterproof unit, 4-cylindrical tube, 5-end cap, 6-discolour silica gel, 7-holes leather hose.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
A kind of gas sampler with water-tight device, as shown in Figure 1, comprise gas sampler 1, the leather hose termination 2 of described gas sampler 1 connects waterproof unit 3, described waterproof unit 3 comprises a cylindrical tube 4, the two ends of described cylindrical tube 4 seal the leather hose termination 2 of installing end cap 5, end cap and connecting gas sampler 1 respectively, and another end cap connects boring leather hose 7; Discolour silica gel 6 is placed with in described cylindrical tube.Discolour silica gel is blue particle shape, very easily absorbs moisture and gradually becomes pink.Can also reuse through super-dry process after water suction.
As shown in Figure 1, during use, the A point of gas sampler connects portable gas explosion somascope, and B point connects firedamp taking-out discharging drilling gaging hole mouth.Once have water to be inhaled in waterproof unit in boring, the color of the discolour silica gel in it can be changing into pink immediately, be very easy to find gas sampler by the change of color and whether suck moisture, placing moisture is drawn in gas detector, not only increase the accuracy rate of extraction data, also avoid gas detection apparatus and cause because sucking moisture damaging.
During concrete enforcement, a waterproof unit is now connect, the diameter 28mm of its cylindrical tube, long 135mm in the leather hose termination that original gas sampler connects, load onto the discolour silica gel of the Absorbable rod moisture of 2-3mm in cylindrical tube, drying process can also be reused.
Gas sampler is the conventional supplementary instrument that underground coal mine measures gas density, after installing waterproof unit additional, achieve good effect.
It should be noted last that; above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail with reference to the utility model embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement; do not depart from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
Claims (2)
1. one kind has the gas sampler of water-tight device, comprise gas sampler (1), it is characterized in that: the leather hose termination (2) of described gas sampler (1) connects waterproof unit (3), described waterproof unit (3) comprises a cylindrical tube (4), the two ends of described cylindrical tube (4) seal respectively installs end cap (5), one end cap connects the leather hose termination (2) of gas sampler (1), and another end cap connects boring leather hose (7); Discolour silica gel (6) is placed with in described cylindrical tube.
2. the gas sampler with water-tight device according to claim 1, is characterized in that: described cylindrical tube (4) diameter 28mm, long 135mm.
