Carrying out air sampling to all parts in coal mine therefore, it is necessary to timing prevents nocuousness to detect the Harmful ingredient content in air
Gas causes a serious accident.
Existing air sampling rig is used as power using pump, and whole device weight is larger, inconvenient to carry.
Utility model content
The purpose of this utility model is to provide a kind of coal mine atmosphere sampling apparatuses light-weight, easy to carry.
Purpose of the utility model is realized as follows: coal mine atmosphere sampling apparatus, including cylinder and elastic sphere, it is described
One end of cylinder is sealed by sealing plate, another end opening, the piston that be internally provided with and the cylinder of cylinder slidingly and sealingly cooperate,
The piston is connected with piston rod, and the piston rod stretches out cylinder, the two sides of the sealing end of the cylinder from the open end of cylinder
Wall is respectively arranged with the first check valve and second one-way valve, and the conducting direction of first check valve is by leading to cylinder outside cylinder
Interior, the conducting direction of second one-way valve is by leading to outside cylinder in cylinder；The two sides of the elastic sphere are respectively arranged with third
Check valve and the 4th check valve, the conducting direction of the third check valve are the by leading in elastic sphere outside elastic sphere the 4th
The conducting direction of check valve is by leading to outside elastic sphere in elastic sphere, and the third check valve and second one-way valve are detachable
Connection, the 4th check valve are connected with exhaust pipe.
Further, the cylinder is transparent plastic barrel.
Further, the elastic sphere is ball.
Further, the third check valve is threadedly coupled with second one-way valve.
The beneficial effects of the utility model are: the present apparatus uses manual hand manipulation, component is less, relatively simple for structure,
Overall volume and weight are smaller, easy to carry.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, the coal mine atmosphere sampling apparatus of the utility model, including cylinder 1 and elastic sphere 2, the cylinder 1
One end sealed by sealing plate 3, be sealing end, another end opening is open end, and cylinder 1 can use metallic cylinder, such as stainless
Steel cylinder or aluminium alloy cylinder, it is preferred to use transparent plastic barrel, the when operation it can be seen that position of internal part.Cylinder 1 it is interior
Portion is provided with the piston 4 slidingly and sealingly cooperated with cylinder 1, and the piston 4 is connected with piston rod 5, and the piston rod 5 is from cylinder
Cylinder 1 is stretched out in 1 open end, pushes piston rod 5 mobile with piston 4, realizes the sucking and discharge of gas.The cylinder
The two sidewalls of 1 sealing end are respectively arranged with the first check valve 6 and second one-way valve 7, the conducting direction of first check valve 6
For by leading in cylinder 1 outside cylinder 1, the conducting direction of second one-way valve 7 is first check valve by leading to outside cylinder 1 in cylinder 1
6 and second one-way valve 7 be used to control air inlet and the outlet position of air, extraneous air can be continuously drawn into cylinder 1 simultaneously
It is discharged from cylinder 1.The two sides of the elastic sphere 2 are respectively arranged with third check valve 8 and the 4th check valve 9, the third
The conducting direction of check valve 8 is by leading in elastic sphere 2 outside elastic sphere 2, and the conducting direction of the 4th check valve 9 is by elasticity
Lead to outside elastic sphere 2 in sphere 2, the third check valve 8 is detachably connected with second one-way valve 7, the 4th check valve 9
It is connected with exhaust pipe 10, hose, such as rubber tube can be used in exhaust pipe 10.Elastic sphere 2 is for storing sample air, inside tool
There is cavity, elastic sphere 2 is using the preferable material of elasticity, such as rubber material.It, can will be elastic by squeezing elastic sphere 2
Gas in sphere 2 is discharged from the 4th check valve 9.Third check valve 8 is detachably connected with second one-way valve 7, is completed in sampling
Afterwards, elastic sphere 2 can be separated from cylinder 1, then squeezes elastic sphere 2, sample air can be passed through exhaust pipe 10
It is discharged into other containers or detection system.In addition it is possible to use different size of elastic sphere 2 is sampled, to adjust sample
The sampling quantity of product air.Preferably, third check valve 8 described in second one-way valve 7 is threadedly coupled with second one-way valve 7, disassembly and
It is all very convenient to install.
The use process of the present apparatus are as follows: after staff carries present apparatus arrival sampled point, elastic sphere 2 is first squeezed, it will
Third check valve 8, is then connected in second one-way valve 7, pushes piston by the air discharge that there is originally in elastic sphere 2
Bar 5 moves back and forth piston rod 5 several times with piston 4, and extraneous air enters cylinder 1 by the first check valve 6, is passing through
Second one-way valve 7 and third check valve 8 enter elastic sphere 2.Piston rod 5 is continued to press on to move back and forth several times, it can will be in device
Originally the air that there is all is discharged.It continues to press on piston rod 5 to move back and forth several times, the gas in elastic sphere 2 can both be made
For sample air.After sample air is carried to laboratory, third check valve 8 is removed from second one-way valve 7, squeezes elasticity
Sample air in elastic sphere 2 can be passed through detection system or other containers by sphere 2.When acquiring sample air, work
Gas mask etc. can be dressed by making personnel, prevent from being poisoned.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
