Abstract
The utility model provides a wind speed, wind pressure and wind volume measuring tube, which comprises a total-pressure cavity (1) and a static-pressure cavity (2). The measuring tube is characterized in that one end of the total-pressure cavity (1) is closed; the other end of the total-pressure cavity (1) is communicated with a micro-pressure differential sensor transmitter through a total-pressure joint (4); more than two total-pressure sampling holes (3) are arranged on a windward side of the lateral wall of the total-pressure cavity (1); one end of the static-pressure cavity (2) is closed; the other end of the static-pressure cavity (2) is communicated with the micro-pressure differential sensor transmitter through a static-pressure joint (5); and more than two pairs of static-pressure sampling holes (6) are correspondingly arranged on two surfaces of the lateral wall of the static-pressure cavity (2) parallel to a wind direction. By respectively arranging a plurality of the sampling holes on the total-pressure cavity and the static-pressure cavity, one measuring tube can be used for measuring the average value of total pressure and static pressure of each point on a straight line, and obtaining measured data with high reliability.

The purpose of this utility model is achieved in that a kind of wind speed, blast, volume measuring pipe, comprises total head chamber and static pressure chamber, it is characterized in that: the end sealing in described total head chamber, and the other end is communicated with minute-pressure difference sensing transducer by the total head joint; The windward side of described total head chamber sidewall is provided with 2 above total head thieff hatchs;
The one end sealing in described static pressure chamber, the other end is communicated with minute-pressure difference sensing transducer by static pressure inlet; The corresponding static pressure thieff hatch that is provided with more than 2 pairs on two faces that are parallel to wind direction of described static pressure chamber sidewall.
For total head mean value and the static pressure mean value that can measure each point on the straight line, described wind speed, blast, volume measuring pipe are preferably linearity.
According to measuring needs, described total head thieff hatch is traditionally arranged to be 5～12, and described static pressure thieff hatch is generally 5～12 pairs, and each total head thieff hatch and corresponding a pair of static pressure thieff hatch coplane; The density degree in pore size and hole can be according to the needs setting of measuring.
In the utility model, the cross sectional shape in total head chamber and static pressure chamber can be provided with as required, and the cross section in described total head chamber generally can be selected circle, square, rhombus or abnormity for use; The cross section in described static pressure chamber generally can be selected circle, square, rhombus or abnormity for use.
The beneficial effects of the utility model are:
1, the utility model can be measured the total head and the static pressure mean value of the each point in the straight line by a measuring tube by on total head chamber and static pressure chamber a plurality of thieff hatchs being set respectively, and the reliable measuring data height is convenient and practical;
2, the utility model preparation technology is simple, and not high, easy to process to the precision requirement of inner structure, financial cost is low;
3, the utility model total head measuring tube and static pressure tube are wholely set, and have saved the space greatly, simplify the structure.
