Abstract
The utility model relates to a weighing container for avoiding evaporation of hot water. A cake-shaped floating roof cover (3) is placed in a weighing container (7); an opening is formed in the middle of the floating roof cover (3) and the outer edge of the floating roof cover (3) is in sliding contact with the inner wall of the weighing container (7); and a flow guide tube (6) penetrates through the opening and extends out of the top of the weighing container (7). The floating roof cover (3) floats on the upper surface of liquid in the weighing container (7), thereby greatly reducing the contact area and volume between the liquid level and air, effectively avoiding the influence of the evaporation of hot water on the measuring accuracy, better realizing measuring work such as certification, calibration of hot water meters, heat energy meters and various hot water flowmeters, and ensuring more accurate and reliable measuring result.
Description
Technical field:
The utility model relates to the container of delicate metering hot water quality and volume, especially prevents the weighing container of hot water evaporation.
Background technology:
At present, in actual measurement, the heat energy table is as the measurement instrument of heating clearing, and its accuracy affects heating enterprise and consumers in general's rights and interests.In actual measurement, if the heat energy table of DN20 is carried out the calibrating that minimum flow is the 50L/h place, be the 100kg container with vessel volume, about a weighing 10kg, need about time 24min (V
K/ V
N) be 9, V wherein
K: the volume of air in the weighing container, V
N: the volume of water in the weighing container, can consider under the limiting case that temperature variation is 5 ℃, other considers other uncertain factor influence, and can influence ultimate value because of the relative uncertainty that the hot water and steam factor produces measurement result is 0.05%, and this amount of influence be can not ignore.Therefore as seen, make V if can improve standard set-up
K/ V
N＜＜1, just can eliminate the influence that measurement result is produced because of the hot water and steam factor, open but correlation technique is not seen.
Summary of the invention:
The purpose of this utility model provides the weighing container of a kind of effective reduction hot water evaporation capacity to be measured, promptly prevents the weighing container of hot water evaporation.
Realize that the measure of the present utility model purpose comprises: settle circular floating top cover in the weighing container, floating top cover outer rim and the sliding contact of weighing container inwall, floating top cover middle part perforate, mozzle passes this perforate and stretches out outside the weighing container top.
The utility model advantage: adopt the interior liquid upper surface of weighing container to add floating top cover, greatly reduce area and the volume that liquid level contacts with air, effectively avoid the influence of hot water evaporation to measuring accuracy, can better realize the calibrating of hot water gauge, heat energy table and various hot water flow meters, the surveying work of calibration, make its measurement result more accurately, reliably.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment 1
Reference numeral comprises: the elbow 1 that makes progress, guide rail 2, floating top cover 3, bearing 4, hot water 5, mozzle 6, weighing container 7, drainpipe 8.
Embodiment:
Embodiment 1:
Settle circular floating top cover 3 in the weighing container 7, floating top cover 3 outer rims and weighing container 7 inwall sliding contacts, floating top cover 3 middle part perforates, mozzle 6 passes this perforate and stretches out outside weighing container 7 tops.
Floating top cover 3 adopts foaming benzene plates to make, and light weight, refuses water, and good buoyancy and heat-insulating property are arranged.Mozzle 6 shapes are carefully grown, and near a jar end, weighing container 7 is a cylindrical can as far as possible, and tank skin adopts insulation material to make.The weighing container 7 inwalls water pipe 8 that outwards runs in.Convenient interior to outer draining from weighing container 7.
Guide rail 2 is vertically fixed in the weighing container 7, floating top cover 3 corresponding fixed guide 2 position perforates.The upper and lower displacement of the floating top cover 3 of guide rail 2 guiding.The floating tight hot water upper surface of top cover 3 pressings, along guide rail 2 steadily drift along up and down and.Three guide rails 2 evenly are vertically fixed in the weighing container 7, and it is interior to upper bottom portion that its lower end is fixed on weighing container 7, guide rail 2 noncontact weighing container 7 inwalls, or its upper end is fixed on weighing container 7 inner tops.
The mozzle 6 of weighing container 7 tops is tilted to the jar end of stretching to weighing container 7 through the elbow 1 that makes progress, but does not contact with at the bottom of the jar.
Weighing container 7 inner bottom parts float top cover 3 below hold-down supports 4.Bearing 4 supports floating top cover 3, so as not to floating top cover 3 drop on weighing container 7 inner bottom parts can not floating.Splendid attire is treated the hot water 5 of weighing in the weighing container 7.
When the utility model embodiment uses, a certain amount of hot water is injected in the weighing container 7 from mozzle 6 through the elbow 1 that makes progress earlier, along with the rising of liquid level, liquid level will be close to floating top cover, produce buoyancy subsequently and will float top cover 3 floatings, move upward together.
Among the utility model embodiment, adopt the floating top cover 3 of liquid upper surface pressure in the weighing container 7, greatly reduce the contact area and the volume of liquid level and air, effectively avoid the influence of hot water evaporation to measuring accuracy, can better realize the calibrating of hot water gauge, heat energy table and various hot water flow meters, the surveying work of calibration, make its measurement result more accurately, reliably.
