Description

Flow rate and direction instrument calibrating installation
Technical field
The utility model relates to technical field of fluid detection, is specifically related to a kind of flow rate and direction instrument calibrating installation.
Background technology
Flow rate and direction instrument is used for flow velocity and the flow direction of test fluid, can deviation be there is in the anglec of rotation that flow rate and direction instrument demonstrates with the actual anglec of rotation, need to be calibrated it by the real conditions under Simulated Water, in prior art, lack suitable device and carry out calibration flow flow speed and direction instrument, be difficult to the accuracy of detection improving flow rate and direction instrument.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aim to provide a kind of structure simple, easy to operate, realize the flow rate and direction instrument calibrating installation that real conditions under Simulated Water calibrates flow rate and direction instrument.
To achieve these goals, the technical solution of the utility model: a kind of flow rate and direction instrument calibrating installation, includes base, described base is positioned with index dial, the center of described index dial is provided with location and flows to current meter and rotatable axle.
Further, described base has groove, and described groove top is seat mouth, and the downside of described index dial is provided with the stopper slot agreed with mutually with described seat mouth, and described index dial is positioned on described seat mouth by this stopper slot.
Further, described axle includes vertically and the mandrel of empty set at described index dial center, described mandrel is installed with the urceolus be positioned at above described index dial, described mandrel lower end is arranged with the bearing be positioned at below described index dial, described bearing is arranged with the axle bed be positioned on the downside of described index dial.
Further, described index dial is marked with the scale mark of 0-360 degree.
The beneficial effects of the utility model: index dial is placed on base by the stopper slot that agrees with and seat mouth, simple and convenient, stability is high, index dial center is provided with rotatable axle, for locating flow rate and direction instrument to be calibrated, the bottom of axle is positioned on axle bed, vertical displacement can not be produced, stabilized structure, index dial is marked with the scale mark of 0-360 degree, accurately can demonstrate the inclination angle of flow rate and direction instrument, realize the calibration to flow rate and direction instrument, improve the precision of flow rate and direction instrument, easy to operate, practical.

Embodiment
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A flow rate and direction instrument calibrating installation as Figure 1-Figure 4, includes base 1, base 1 is positioned with index dial 2, and the center of index dial 2 is provided with location and flows to current meter and rotatable axle 3.
Preferably, base 1 has groove 11, and groove 11 top is seat mouth 12, and the downside of index dial 2 is provided with the stopper slot 21 agreed with mutually with seat mouth 12, and index dial 2 is by the present mouth 12 in this stopper slot 21 location.
Axle 3 includes vertically and the mandrel 32 of empty set at index dial 2 center, mandrel 32 is installed with the urceolus 31 be positioned at above index dial 2, mandrel 32 lower end is arranged with the bearing 34 be positioned at below index dial 2, urceolus 31 and mandrel 32 synchronous rotary, the lower end of urceolus 31 abuts on index dial 2, urceolus 31 can be effectively avoided displacement straight down to occur and then affects calibration, bearing 34 is arranged with the axle bed 33 be positioned on the downside of index dial 2, preferably, axle bed 33 is welded on the downside of index dial 2, the lower end of mandrel 32 and the lower end of bearing 34 are in same level, axle bed 33 is spacing at vertical direction to mandrel 32 further, simultaneously, axle bed 33 also positions bearing 34, stabilized structure, index dial 2 is marked with the scale mark of 0-360 degree, be convenient to reading calibration.
Use procedure of the present utility model is as follows: first take off index dial 2, the groove 11 of base 1 is placed the compass instrument of standard, after carrying out mark according to pointed, take out compass, put index dial 2, guarantee that mark overlaps with the zero degree of index dial 2, realize calibrating the reference position of index dial 2, when placing index dial 2, guarantee that the stopper slot 21 on the downside of index dial 2 engages on present mouth 12, stabilized structure, can not affect calibration because position skew occurs index dial 2.Again flow rate and direction instrument to be calibrated is plugged on urceolus 31, corresponding scale on deflected stream flow speed and direction instrument to index dial 2, gets final product the deflection angle that calibration flow flow speed and direction instrument shows, and then improve the precision of flow rate and direction instrument.This process is calibrated flow rate and direction instrument by the underwater deflection state of analog stream flow speed and direction instrument.
The utility model structure is simple, easy to operate, stabilized structure, is calibrated, significantly improve the accuracy of detection of flow rate and direction instrument by the underwater deflection state of analog stream flow speed and direction instrument to flow rate and direction instrument.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, embodiment and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
