Description
Technical field
The utility model relates to instrument measurement supplementary instrument technical field, especially relates to a kind of online Density Measuring Instrument servicing unit.
Background technology
Now industrial product quality is more and more paid attention to, fluid density value is as important product quality indicator, also can indirectly converse by the measurement of fluid density the important physical parameters such as strength of fluid, mass percent, percentage of solids, API degree, balling degree, the control of the duty parameter to intermediate products and final products proposes higher required precision. Industrial conventional Density Measuring Instrument has tuning fork Density Measuring Instrument, differential Density Measuring Instrument, the measurement devices such as floatage-type Density Measuring Instrument. Accurately reliable when existing these measurement devices are mainly measured static liquid density, but directly the interior working fluid density of measuring channel has strict flow velocity requirement, conventionally requires liquid flow velocity lower than 0.5m/s.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of liquid flow velocity in main pipeline is controlled to the online Density Measuring Instrument aided measurement device below 0.5m/s.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is a kind of online Density Measuring Instrument servicing unit, comprises main pipeline, drainage tube, circulation chamber and return duct; On described main pipeline, be respectively arranged with upstream valve and valve downstream; Described drainage tube is T shape, and one end of T shape connects upstream valve, and another two ends connect respectively the top and bottom of circulation chamber; Described circulation chamber is vertically mounted on main pipeline; Described circulation chamber upper end arranges air bleeding valve, and lower end arranges lets out dirty valve; Described return duct one end is connected with circulation chamber, and the other end is connected with main pipeline by valve downstream.
Compared with prior art, the beneficial effects of the utility model are: this on-line measurement instrument auxiliary device is simple in structure, safe and reliable and convenient for installation and maintenance, easy to use, effectively solve Density Measuring Instrument in the time that working fluid flow velocity exceedes in measurement main pipeline when 0.5m/s, the accurately defect of fluid density, increases in measuring instrument use and measures accuracy.
Brief description of the drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is main structure schematic diagram of the present utility model.
Mark in figure: main pipeline 1, drainage tube 2, circulation chamber 3, return duct 4, upstream valve 5 and valve downstream 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in fig. 1, the utility model is a kind of online Density Measuring Instrument servicing unit, comprises main pipeline 1, drainage tube 2, circulation chamber 3 and return duct 4; On described main pipeline 1, be respectively arranged with upstream valve 5 and valve downstream 6; Described drainage tube 2 is T shape, and one end of T shape connects upstream valve 5, and another two ends connect respectively the top and bottom of circulation chamber 3; Described circulation chamber 3 is vertically mounted on main pipeline 1; Described circulation chamber 3 upper ends arrange air bleeding valve 7, and lower end arranges lets out dirty valve 8; Described return duct 4 one end are connected with circulation chamber 3, and the other end is connected with main pipeline 1 by valve downstream 6.
This device is the servicing unit of online Density Measuring Instrument, and online Density Measuring Instrument is arranged on circulation chamber 3 top flanges, and online Density Measuring Instrument sensor is positioned at circulation chamber position of center line. The upstream valve 5 and the valve downstream 6 that on main pipeline 1, arrange, control fluid to be measured flows to the break-make of this servicing unit; The air bleeding valve 7 of circulation chamber 3 upper ends, can discharge in circulation chamber 3 gas of assembling, lower end let out dirty valve 8, convenient in the time of repair and maintenance, discharge the indoor sediment of circulation. This device utilizes the design of hydrodynamics fluid law of continuity. This servicing unit is arranged on the main pipeline that fluid to be measured flows through, fluid to be measured is back to main pipeline 1 from main pipeline 1 shunting circulates chamber, therefore upstream valve 5 is identical with main pipeline 1 fluid to be measured flow velocity with valve downstream 6 flow velocitys, and upstream and downstream valve fluid flow equates. In the time that fluid to be measured flows to circulation chamber 3, the interior cross-sectional area that flows to of circulation chamber 3 increases, and fluid to be measured flow velocity declines, and circulation chamber 3 center flow velocitys are multiplied by main pipeline 1 flow velocity for shunting cross-sectional area, then divided by circulation chamber 3 center cross-sectional areas. As: drainage tube 2 and return duct 4 for nominal diameter be 25 millimeters of pipelines, upstream and downstream valve is that nominal diameter is the ball valve of 25 millimeters, circulation chamber 3 is of a size of 50 millimeters of diameters, long 1000 millimeters. Can calculate shunting cross-sectional area is: area of a circle π r*r=491 square millimeter; Circulation chamber center cross-sectional area is: the long L=50*1000=50000 square millimeter of diameter D*; Main pipeline flow velocity is 50000 ÷ 491=102 times of circulation chamber centerline flow velocity; Suppose that circulation chamber centerline flow velocity is 0.5m/s, after this device subsidiary, main pipeline flow velocity maximum detection 51m/s. Online Density Measuring Instrument is by after this device subsidiary fluid density, and value is more stable, and while being greater than 0.5m/s for pipe flow speed, online Density Measuring Instrument also can accurately be measured its fluid density.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
