Abstract

The utility model relates to a flow measurement device, in particular to a plug-in multi point anemometer, which solves the problem of flow measurement for small straight pipe section of various middle sized and small sized pipes, and not only retains the advantages such as low pressure loss and convenient installation and maintenance for the flow device, but also makes the new device realize the function and characteristic of cross-section measurement. The utility model takes bar type flow meters including an averaging pitot-tube as a base, and achieves the effect of measuring a plurality of averaging pitot-tubes, thereby ensuring the average measurement of the flow velocity and the flow for the whole cross-section. In the technical scheme, the plug-in multi point anemometer comprises pitot-tubes, and the pitot-tubes can be divided into a vertical pitot-tube and a horizontal pitot-tube, and the pitot-tubes arranged in a mutually perpendicular way.

Description

A kind of plug-in type multiple spot wind speed flowmeter

Technical field

The utility model relates to a kind of flow measurement device, especially relates to a kind of plug-in type multiple spot wind speed flowmeter.

Background technology

At present, steam boiler present popular Circulating Fluidized Bed Boiler particularly in the fuel-burning power plant with high environmental protection and high energy efficiency, need to a large amount of various in, the air mass flow of small size pipeline measures, and has following problem in metering:

In various, the small size pipeline is owing to install straight length very in short-term, crust class flowmeters such as conventional plug-in type Pitot-static tube need the above combination of two covers just normally to measure, install and construction very inconvenient;

2. when on-the-spot air quantity device commonly used at present used before and after adjustment doors, its output was linear relatively poor, is difficult to satisfy measurement requirement, and usable range is restricted.

The utility model content

The utility model provides a kind of plug-in type multiple spot wind speed flowmeter in order to solve the weak point in the above-mentioned background technology, and it has the convenience of I﹠M, the less pressure loss, again can the multiple spot pressure, guarantee the linear adjustment of measuring.

For achieving the above object, the technical solution adopted in the utility model is: a kind of plug-in type multiple spot wind speed flowmeter, comprise pitot tube, and it is characterized in that: the orthogonal setting of described pitot tube.

The pitot tube of described orthogonal setting comprises a vertical pitot tube and a plurality of horizontal pitot tube.

The pitot tube of described orthogonal setting comprises a plurality of vertical pitot tubes and a horizontal pitot tube.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1. the utility model has utilized the measuring principle and the design feature of even speed tube, and a plurality of average rate measuring tubes are combined becomes a brand-new flow measurement device;

2. the utility model is can be directly installed on before and after the adjustment doors, has solved the difficult problem of Circulating Fluidized Bed Boiler air measuring.

Description of drawings

Fig. 1 is the structural representation that the utility model is installed at circular pipe;

Fig. 2 is the structural representation that the utility model is installed at square pipe.

Among the figure, 1-tested pipeline, the vertical pitot tube of 2-, the horizontal pitot tube of 3-

Embodiment

The utility model comprises pitot tube, and described pitot tube is divided into vertical pitot tube 2 and horizontal pitot tube 3, and the orthogonal setting of pitot tube,

Referring to Fig. 1, Fig. 1 is circular tested pipeline 1, comprises 3, one vertical pitot tubes 2 of a vertical pitot tube 2 and a plurality of horizontal pitot tube and the 3 orthogonal settings of a plurality of horizontal pitot tube.

Referring to Fig. 2, Fig. 2 is the tested pipeline 1 of rectangle, comprises a plurality of vertical pitot tubes 2 and a horizontal pitot tube 3.A plurality of vertical pitot tubes 2 and horizontal pitot tube 3 orthogonal settings.

The utility model is installed in the tested pipeline 1, can reach the multimetering to the whole pipe cross section; Because multiple spot cross section formula metering method, can be used for the uneven occasions in flow field such as adjustment doors, be used for flow metering and test various, the small size pipeline, be to count the basis with crust class flows such as mean velocity tube flowmeters, determine final point position and measuring point quantity according to the process structure of tested pipeline, use the utility model flow apparatus, the result of use highly significant can be installed and safeguard easily.
