Obtain a more stable value to carry out next step instructs work, it is therefore desirable to which designing one kind can be by differential pressure extraction tube
The probe structure of wind speed variable in road is very necessary.
Utility model content
The problem of for background technology, the utility model provide a kind of air volume meter with flat wind probe.
To achieve the above object, the utility model provides following technical solution：The flat wind probe of a kind of air volume meter, including just
Be pressed into air hose, negative-pressure inlet pipe and connecting tube of end, the positive pressure blast pipe is sealed with the equal one end of negative-pressure inlet pipe, the other end with
Connecting tube of end is connected, offered respectively on the positive pressure blast pipe and negative-pressure inlet pipe side wall positive pressure air inlet hole and negative pressure into
Air holes hole, the positive pressure air inlet hole are located at opposite facade with negative-pressure inlet hole, positive pressure are provided on the connecting tube of end
Connector and negative pressure connector, the positive pressure connector is corresponding with the air outlet of positive pressure blast pipe, and the negative pressure connector is with bearing
The air outlet for being pressed into air hose is corresponding.
As a kind of preferred technical solution of the utility model, the positive pressure blast pipe on negative-pressure inlet pipe side wall with opening up
Hole to be several, and be uniformly distributed.
As a kind of preferred technical solution of the utility model, fixing device is provided with outside the connecting tube of end.
As a kind of preferred technical solution of the utility model, the fixing device include be provided with externally threaded screwed pipe with
Adjusting nut, the adjusting nut are threadedly connected on screwed pipe.
As a kind of preferred technical solution of the utility model, the positive pressure connector on negative pressure connector with offering
Due to the internal thread structure of connection.
Compared with prior art, the beneficial effects of the utility model are：The utility model passes through positive pressure blast pipe and negative pressure
The design of blast pipe can more carry out the wind speed of flow-disturbing in pipeline average extraction, global design practicality simple for structure, cost
It is at low cost, operation is easily installed, there is more vast market prospect, convenient for promoting.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Embodiment：
It please refers to Fig.1 and Fig. 2, the utility model provides a kind of flat wind probe of air volume meter, including positive pressure blast pipe 1, bear
Air hose 2 and connecting tube of end 3 are pressed into, the positive pressure blast pipe 1 is sealed with 2 equal one end of negative-pressure inlet pipe, and the other end connects with end
Take over 3 is connected, and offers positive pressure air inlet hole 4 and negative-pressure inlet on the positive pressure blast pipe 1 and 2 side wall of negative-pressure inlet pipe respectively
Hole 5, the positive pressure air inlet hole 4 are located at opposite facade with negative-pressure inlet hole 5, are provided with just on the connecting tube of end 3
Connector 6 and negative pressure connector 7 are pressed, the positive pressure connector 6 is corresponding with the air outlet of positive pressure blast pipe 1, the negative pressure connection
First 7 is corresponding with the air outlet of negative-pressure inlet pipe 2.
The utility model is measured by the way that positive pressure blast pipe 1 and negative-pressure inlet pipe 2 are inserted into air hose, positive pressure blast pipe 1
On positive pressure air inlet hole 4 need ensure it is perpendicular with wind speed direction, misalignment angle control within 3 °, negative-pressure inlet hole 5
Back to wind speed direction, to be entered in connecting tube of end 3 by positive pressure and negative pressure, then being divided using guiding tube is (not shown) simultaneously
Not Lian Jie positive pressure connector 6 and partial pressure connector 7, the wind speed in positive pressure blast pipe 1 and negative-pressure inlet pipe 2 is transmitted to air volume meter
It carries out calculating in (not shown) average.
Specifically, the positive pressure blast pipe 1 is several with the hole opened up on 2 side wall of negative-pressure inlet pipe, and it is uniformly distributed,
The wind conditions in air hose are comprehensively extracted as possible.
Specifically, being provided with fixing device 8 outside the connecting tube of end 3, the further fixing device 8 includes setting
