One end connection of the 3rd electromagnetic valve 6 outside seal box 2；The seal box 2 is provided with air inlet 7 and air vent 8, institute
State air vent 8 to connect with one end of first electromagnetic valve 4, the other end of first electromagnetic valve 4 and the air inlet of the air pump 3
End connection, the exhaust end of the air pump 3 connect with one end of second electromagnetic valve 5, the other end of second electromagnetic valve 5 and
The air inlet 7 is connected.
The air vent 8 is connected by the first next door ferrule fitting 11 with one end of first electromagnetic valve 4, and described second
The other end of electromagnetic valve 5 is connected by the second next door ferrule fitting 12 with the air inlet 7, first next door ferrule fitting 11
The upper end of the seal box 2 is separately fixed at second next door ferrule fitting 12.
The bag mouth of the airbag 1 is connected by the 3rd next door ferrule fitting 13 with one end of the 3rd electromagnetic valve 6,
The other end connection trachea of the 3rd electromagnetic valve 6, and trachea is guided in surrounding air or at discharge of pollutant sources, the described 3rd
Next door ferrule fitting 13 is fixed on the lower end of the seal box 2.
Airbag 1 is mounted in the good seal box 2 of sealing, the air inlet 7 of seal box 2, air vent 8 are filled respectively with trachea
It is connected with the tank wall of seal box 2 in next door ferrule fitting 12,11.Air vent 8 is used for the collection of sample gas in airbag, air inlet
7 emptyings for being used for sample gas.
All next door ferrule fittings need to ensure that sealing is air tight with the junction of seal box.
In this utility model, the sampling mechanism is four sets, four sets of sampling mechanisms by the way of in parallel, by two
Tetrad electromagnetic valve carries out parallel connection, wherein, the electromagnetic valve 5 of first electromagnetic valve 4 and second adopts tetrad electromagnetic valve, four air inlets
Mouth is connected with one end of a tetrad electromagnetic valve, and a tetrad electromagnetic valve is made up of four electromagnetic valves 4-1,4-2,4-3,4-4,
Four air vents are connected with one end of another tetrad electromagnetic valve, and another tetrad electromagnetic valve is also by four electromagnetic valve 5-
1st, 5-2,5-3,5-4 are constituted.The inlet end of the first electromagnetic valve 4 is connected with monomer electromagnetic valve 9, the outlet side of the second electromagnetic valve 5 with
Monomer electromagnetic valve 10 connects.
The structure of tetrad electromagnetic valve is as shown in Fig. 2 during tetrad electromagnetic valve work, airflow direction enters P and brings out by A ends, tetrad
Solenoid valve base inside A, P end is the circular pipe of direct connection, not by top electromagnetic valve state control.The interface of lower section four
Inlet, outlet state receives respectively top solenoid valve control, four electromagnetic valves can independent control, without mutually dry between break-make electricity condition
Disturb.The interface of monomer electromagnetic valve 9 and 10 is connected with A ends or P ends.
Four sets of sampling mechanism operation principles in parallel are as follows：
Step one：In Fig. 1, airbag is mounted in a good seal box of sealing, and by the valve opening on airbag.
Step 2：Need first to empty the gas of original state in airbag, then be inflated process.When emptying to airbag,
Control system sends order, and monomer electromagnetic valve 9 is opened, and electromagnetic valve 4-1 is closed, and electromagnetic valve 5-1 is opened, and electromagnetic valve 10 is closed,
Opens solenoid valve 6-1.So, when air pump works, inflation will not be stopped toward in seal box, is formed more than the air pressure inside airbag,
Because electromagnetic valve 6-1 is to open, the high pressure in seal box will be extruded in airbag, certain hour and arrange the gas in airbag
Sky, the time is depending on airbag volume.Complete an exhaust process.
Step 3：To air bag inflator, when air pump is started working electromagnetic valve 9 is closed with control system, on electromagnetic valve 4-1
Electric-opening, the airflow direction of the air pump left-to-right from figure, closes electromagnetic valve 5-1, opens solenoid valve 10.Electromagnetic valve 6-1 also goes up electricity
Open, now, a vacuum state is formed in seal box.Because airbag has the trachea being in communication with the outside, in order to keep sealing
Air pressure balance in case, airbag by with seal box in draught head, automatically from seal box outside air inlet, according to the size of airbag
Determine that the time that airbag is full of, airbag close electromagnetic valve 6-1 after being full of, so complete a gas and keep sample process.
Airbag (2), airbag (3), the inflation of airbag (4) and venting principleand are identical with airbag (1).
Gas circuit ventilation when solenoid valve control mode used in this utility model is upper electric, then gas circuit is closed for power-off；
If using the electromagnetic valve of contrary control mode, i.e. power-off ventilation, the control mode of upper electricity closure, then this practicality is new
Type is to airbag aerofluxuss and the mode contrast inflated.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
