Fig. 2 is portable Atmospheric particulates on-line monitoring equipment thief hatch structural front view of the present utility model；
Fig. 3 for Fig. 2 A-A to sectional view.
Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
The utility model provides a kind of portable Atmospheric particulates on-line monitoring equipment sampling mouth structure, as Figure 1-3,
Including sampling pipe 1 and top cap 2, the bottom of sampling pipe 1 is used to be connected with portable Atmospheric particulates on-line monitoring equipment, sampling pipe
1 top is connected with top cap 2, and the diameter of top cap 2 is more than the diameter of sampling pipe 1.
When in use, the bottom of sampling pipe monitors the inside gas of equipment on-line with portable Atmospheric particulates to the utility model
Road is connected, in the presence of sampling pump, produces negative pressure, and air is monitored on-line from sampling pipe top into portable Atmospheric particulates
Equipment, because the top of sampling pipe sets crown cap, also, diameter of the diameter more than sampling pipe of top cap so that sleet etc. is different
Thing do not fallen out into thief hatch, it is to avoid the problem of thief hatch is blocked or testing result is inaccurate.
In the utility model, sampling pipe 1 can have various structures, and one of which includes sampling tube body 3 and projecting tube 4,
Projecting tube 4 is arranged on sampling tube body 3 upper end.Projecting tube reaches the lower section of top cap, receives the protection of top cap, it is to avoid foreign matter is from outer
Stretch pipe and drop to sampling tube body, hence into device interior.
Accordingly, top cap 2 can include top cap body 5 and connecting portion 6, and top cap body 5 is arranged on the top of connecting portion 6,
Top cap body 5 and connecting portion 6 are connected by supporting rib 7.Air enters sampling from the space between top cap body and connecting portion
Pipe, particularly into projecting tube.
Top cap and the connected mode of sampling pipe have a variety of, specifically, the sampling upper end of tube body 3 and the lower end of connecting portion 6 pass through
Threaded connection, wherein：The upper end of tube body 3 sample provided with external screw thread, tube body upper end of now sampling is variable-diameter structure, and its diameter leads to
Cross a step structure to attenuate, the lower end of connecting portion 6 is provided with internal thread.
In order to ensure effective protection of the top cap to sampling pipe, the diameter of top cap body 5 is more than the diameter of connecting portion 6, connection
The diameter in portion 6 is more than or equal to the diameter of sampling tube body 3, and the diameter of sampling tube body 3 is more than the diameter of projecting tube 4.So that
Structure in addition to top cap is all blocked by top cap to be protected.
