Abstract
The utility model relates to a plug-in type rectifier type flow measurement device, which can stabilize the flow field of measuring points, extend the range of use of the plug-in type flow measurement device, improve the accuracy in measurement and stabilize output signals. The utility model comprises a plug-in type flow device, a fluid rectifier is additionally arranged on each measuring point of the plug-in type flow device, and the fluid rectifier can be the grid type, circular pipe shape, bore hole type or combined fluid rectifier.
Description
One, technical field:
The utility model relates to a kind of flow measurement device, especially relates to a kind of plug-in type rectification type flow measurement device.
Two, background technology:
At present, the particularly present popular Circulating Fluidized Bed Boiler with high environmental protection and high energy efficiency of steam boiler need be carried out the air mass flow metering to the various sizes pipeline that the straight length deficiency is installed in the fuel-burning power plant, carries out the air mass flow metering and has following problem:
In, when large-scale pipeline is installed, measure the measurement requirement that straight length is difficult to satisfy common plug-in type flow meter; And flowmeters such as operable wing are because the volume heaviness is installed very difficulty;
2. on-the-spot all kinds of plug-in type flow meters commonly used at present because the eddy current that the straight length deficiency causes causes influence greatly to measurement, are difficult to guarantee measuring accuracy.
Three, utility model content:
The utility model provides a kind of plug-in type rectification type flow measurement device in order to solve the weak point in the above-mentioned background technology, and it can be stablized the measuring point flow field, enlarge the usable range of insert type flow measuring device, improves measuring accuracy, stablizes output signal.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of plug-in type rectification type flow measurement device comprises the plug-in type flow device, it is characterized in that: each the measuring point place at the plug-in type flow device adds fluid rectifier.
Above-mentioned fluid rectifier is fixed on the porch of the built-in straight length of plug-in type flow device.
Above-mentioned fluid rectifier is pattern, tubular type, drilling hole type or combined fluid rectifier.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utility model is on the basis of plug-in type flow devices such as existing plug-in type double throat diameter flow measurement device, many larynxs of plug-in type run-off measurement mechanism, plug-in type multiple spot average rate double throat diameter flow apparatus, install additional after the fluid rectifier, can reach and stablize the measuring point flow field, further enlarge its accommodation;
2, the utility model can improve the accuracy of flow velocity (flow) metering; When straight length is not enough, use this device can carry out accurate flow velocity or flow metering;
3, the utility model and plug-in type flow matched with devices are used, and do not influence its other usability; Obtain rectification owing to enter the fluidised form of measurement links, can obtain more stable output signal.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-plug-in type flow device, 2-fluid rectifier.
Five, embodiment:
The utility model is to install fluid rectifier additional and form on the basis of existing plug-in type flow device, forms a brand-new plug-in type rectification type flow apparatus.Comprise a plug-in type flow device and one or more fluid rectifier, install fluid rectifier additional, make the fluid that enters measurement links at first obtain rectification at each measuring point place of plug-in type flow device.Referring to Fig. 1; plug-in type flow device 1 is a double throat diameter series flow apparatus; also can be that many larynxs of plug-in type run-off measurement mechanism, plug-in type multiple spot average rate double throat diameter flow apparatus and other have plug-in type flow device of built-in straight length etc., all within protection domain of the present utility model.Be fixed on the porch of the built-in straight length of plug-in type flow device 1 according to the fluid rectifier 2 of the relative dimensions of plug-in type flow device 1 processing, can constitute a brand-new rectification type flow apparatus.Wherein fluid rectifier 2 is pattern, tubular type, drilling hole type or combined fluid rectifier, and pattern is to utilize thin plate to be divided into the shape of grid; Tubular type is made up of the identical or different light wall pipe wall of specification; Drilling hole type: adopt the method for machining to make; Combined for adopting pipe and thin plate to be divided into the rectifier of arbitrary shape, be existing fluid rectifier.
During real work, measured medium at first carries out rectification through 2 pairs of detected fluid of fluid rectifier before the measurement links that enters plug-in type flow device 1, make the eddy current fluidised form that exists in the medium fully change disturbed flow condition into, and then carry out the flow velocity metering, export differential pressure signal at last;
Principle of the present utility model is:
When the mounting process straight length is not enough, the medium fluidised form forms the eddy current state easily, after the measured medium fluid of this state is entered by the inlet of plug-in type flow device 1, passed through the abundant rectification of fluid rectifier 2, the fluidised form of measured medium will change the disturbed flow condition that meets bernoulli equation, attains full development into, enter flow velocity metering link this moment again, the differential pressure signal of its generation will reflect the flow velocity size of measured point more accurately.
