Abstract
The utility model discloses a tester for the resistance force of an absorption bottle. The tester comprises a housing, a negative pressure gauge, a filter well, a flow gauge and a vacuum pump. The absorption bottle, the filter well, the flow gauge and the vacuum pump are communicated with one another through connecting pipes; the negative pressure gauge is connected to a connecting pipe connected between the filter well and the absorption bottle; and the filter well, the flow gauge and the vacuum pump are mounted in the housing; a drier is also arranged between the filter well and the flow gauge; the drier is communicated with the filter well and the flow gauge respectively through connecting pipes; the tester further comprises a bearing frame for supporting the absorption bottle; and the bearing frame is arranged at the upper end part or in the interior of the case. The tester for the resistance force of the absorption bottle has a simple structure and is convenient to use, the measured value of the resistance force is accurate, and the tester is suitable for being popularized and used in the ambient air quality monitoring or disease control fields.
Description
Technical field
The utility model relates to a kind of instrument that is used for the ambient air quality monitoring, particularly relates to the absorption bottle measure of resistance instrument that a kind of absorption bottle that is used for the usefulness of monitoring samplings such as indoor and outdoor surroundings detection, occupational health carries out measure of resistance.
Background technology
At present, in the ambient air quality monitoring, the method for atmospheric sampling mainly is divided into two classes, and the first kind is the sampling of particle shape pollutant, and second class is the sampling of gaseous contaminant.The most frequently used method of the sampling of gaseous contaminant is a solution absorption method, this method is to use and varies in size, different absorption bottle, gaseous contaminant such as sulphuric dioxide, carbon monoxide and formaldehyde etc. are concentrated in the absorption liquid in the absorption bottle, then the sample of these collections are under lab analyzed, handled with analytical instrument.Be to guarantee sampling quality, newly purchase or use the absorption bottle after the stipulated time must carry out measure of resistance by the environment monitoring and quality control requirement, and its measure of resistance value should meet in the scope of national regulation, undesirable person then can not use.But the instrument that still none cover is complete so far on the market detects at the resistance of absorption bottle, and therefore, design one cover can be extremely urgent to the instrument that the absorption bottle resistance detects.
The utility model content
The technical problems to be solved in the utility model provides a kind of can the resistance of absorption bottle the detection, and absorption bottle measure of resistance instrument simple in structure.
For solving the problems of the technologies described above, the utility model adopts so a kind of absorption bottle measure of resistance instrument, and it comprises casing, vacuum table, drainage well, flowmeter and vacuum pump; Be connected by connecting pipe between described absorption bottle, drainage well, flowmeter and the vacuum pump, described vacuum table is connected on the connecting pipe between described drainage well and the absorption bottle, and described drainage well, flowmeter and vacuum pump are installed in the described casing.
Described analyzer also comprises a bearing support that is used to support described absorption bottle, and this bearing support is arranged on the upper end or the inside of described casing.
After adopting said structure, when measuring, start vacuum pump, air is through absorption bottle, drainage well and flowmeter, after vacuum pump discharge, because vacuum table is connected on the connecting pipe between drainage well and the absorption bottle, therefore in the vacuum pump pumping process, under the air mass flow of regulation, the reading of vacuum table is the Resistance Value of absorption bottle; In addition, because the parts that the utility model adopts are less, thereby simple in structure, be convenient to make and install.
As further improvement of the utility model, between described drainage well and flowmeter, also be provided with exsiccator, this exsiccator is connected with described drainage well and flowmeter respectively by connecting pipe.Adopt such structure, exsiccator can not only play and prevent that the water in air steam from entering flowmeter and causing flow error, and can avoid water vapor to enter vacuum pump and the accident of damaging vacuum pump takes place.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model absorption bottle measure of resistance instrument.
Embodiment
A kind of absorption bottle measure of resistance instrument referring to shown in Figure 1 comprises rectangular casing 1, vacuum table 2, the drainage well 3 that is used for filtered air moisture content, flowmeter 4 and vacuum pump 5; Be connected by connecting pipe 7 between described absorption bottle 6, drainage well 3, flowmeter 4 and the vacuum pump 5; Described vacuum table 2 is connected on the connecting pipe 7 between described drainage well 3 and the absorption bottle 6 by three-way pipe 10, and the dial plate of vacuum table 2 is embedded on the side plate of casing 1 so that observe; Described drainage well 3, flowmeter 4 and vacuum pump 5 are installed in the casing 1, and described vacuum pump 5 is electrically connected with power switch 11.
In absorption bottle measure of resistance process, for preventing that the water in air steam from entering flowmeter 4 and causing flow error, and prevent water vapor from entering vacuum pump 5 and with its damage, can between described drainage well 3 and flowmeter 4, exsiccator 8 be set, this exsiccator 8 is connected with described drainage well 3 and flowmeter 4 respectively by connecting pipe 7, air is before entering flowmeter 4 like this, and airborne water vapor is all absorbed by described exsiccator 8.In addition, in the utility model, but in described drainage well 3 little and the polyfoam of filling air flow resistance also with good gas penetration potential, flexibility, not shown in the figures.
Because absorption bottle 6 varies in size, different, shown in the figure only is the profile a kind of commonly used of absorption bottle 6, i.e. bubble U type tubular type absorption bottle.For in the measure of resistance process, making these absorption bottles 6 be in a stable status, can be in the upper end of described casing 1 or innerly be provided with one and be used to support or the bearing support 9 of clamping absorption bottle 6.
The course of work of the present utility model is as follows: power-on switch 11 starts vacuum pump 5, makes air flow to other end 6-2 from an end 6-1 of absorption bottle 6, and behind three-way pipe 10, drainage well 3, exsiccator 8 and flowmeter 4, is discharged by vacuum pump 5; In the mensuration process, vacuum pump 5 is bled with the flow of the specified liter of per minute, and the reading that vacuum table 2 shows is the Resistance Value of absorption bottle 6.
The utility model is through on probation, and it is simple in structure, and is easy to use, and the measure of resistance value is accurate, has obtained good effect.
