Technical field
The utility model relates to the technology that object density is measured, special relevant with pneumatic process volume measurement device.
Background technology
At present, what object density was measured employing to irregular contour article volume in measuring is fluid-discharge therapy and sand discharge method, but, some is met to physical property of liquid can change and fluff type article, be afraid of the article that pollute, damage, just cannot adopt the modes such as measurement size, fluid-discharge therapy, sand discharge method to measure calculating.
Through inquiring about a lot of documents, do not find the correlation report that adopts pneumatic process measurement volumes.In order to address the above problem, the inventor specially for meet physical property of liquid can change, fluff type article and be afraid of pollute, damage article, the structure of the volume measurement device in the time carrying out density measure re-starts design, then have this case produce.
Utility model content
The purpose of this utility model is to provide a kind of pneumatic process volume measurement device, and to facilitate, fluff type article and the fearness that end-on physical property of liquid can change polluted, the cubing of the article of damage in the time of density measure.
To achieve these goals, solution of the present utility model is:
Pneumatic process volume measurement device, formed by the first closed container, the second closed container, barometer, container pressure table, the first valve, the second valve and the 3rd valve, the first valve is installed in the first closed container upper end, the second valve and container pressure table are installed on the second closed container, between the first closed container and the second closed container, are communicated with by the 3rd valve.
Described the first closed container has cylinder body and upper cover, and upper cover is bolted on cylinder body, between upper cover and cylinder body, is provided with O-ring seal, and the first valve installation covers upper.
Described the second closed container has cylinder body and upper cover, and upper cover is bolted on cylinder body, between upper cover and cylinder body, is provided with O-ring seal, and the second valve and container pressure table are arranged on and cover.
The precision of described barometer is 0.4 grade, and the range of container pressure table is 0.1 ~ 0.6Mpa, and precision is 0.4 grade.
Described the first closed container and the second closed container volume equate.
When the utility model uses, for measuring the volume of sample, then measure the quality of sample, finally draw the density of sample.
Adopt after such scheme, the utility model is according to Boyle one boyle's law, quantitative gas in closed container, under constant temperature, the pressure of gas and the volume relation that is inversely proportional to, studies and designs the device of measuring article volume, measures the volume of particular matter by the variation of gaseous tension in closed container, thereby measure the density of article, greatly facilitate and meet physical property of liquid the fluff type article that can change and the article density measure of being afraid of pollution, damage.
Brief description of the drawings
Fig. 1 is apparatus structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model has disclosed pneumatic process volume measurement device, is made up of the first closed container 1, the second closed container 2, barometer 3, container pressure table 4, the first valve 5, the second valve 6 and the 3rd valve 7.
The first valve 5 is installed in the first closed container 1 upper end.In order to be convenient for measuring, the first closed container 1 has cylinder body 11 and upper cover 12, and upper cover 12 is fixed on cylinder body 11 by bolt 13, is provided with O-ring seal 14, the first valves 5 and is arranged on upper cover 12 between upper cover 12 and cylinder body 11.
The second valve 6 and container pressure table 4 are installed on the second closed container 2.In order to be convenient for measuring, the second closed container 2 has cylinder body 21 and upper cover 22, and upper cover 22 is fixed on cylinder body 21 by bolt 23, is provided with O-ring seal 24, the second valves and container pressure table and is arranged on and covers between upper cover 22 and cylinder body 21.In order to improve the accuracy of measurement, suggestion the first closed container 1 and the second closed container 2 volumes equate or slightly equate.
Between the first closed container 1 and the second closed container 2, be communicated with by the 3rd valve 7.
Barometer 3 is for measuring atmospheric pressure, and in order to improve the accuracy of measurement, it is 0.4 grade that the precision of barometer 3 is selected in suggestion.
Container pressure table 4 is for measuring the pressure in the second closed container 2, and in order to improve the accuracy of measurement, it is 0.1 ~ 0.6Mpa that the range of container pressure table 4 is selected in suggestion, and precision is 0.4 grade.
When the utility model uses, carry out the cubing of sample, then measure the quality of sample by device as shown in Figure 1, finally draw the density of sample, concrete steps are as follows:
The first step, is 0.3 ~ 0.4mpa pressurized air by the second valve 6 to being filled with air pressure in the second closed container 2, and the volume of the second closed container 2 is Tb cubic meter;
Second step, puts into the first closed container 1 by sample, and airtight good, and the volume of sample is made as Ty cubic meter, and Ty is between 0.4Ta ~ 0.6Ta in suggestion;
The 3rd step, opens the first valve 5, and the first closed container 1 is communicated with atmosphere, allows the first closed container 1 air pressure equate that with atmosphere closing the first valve 5, the first closed container 1 volumes after stable is Ta cubic meter (Ta is close with Tb in suggestion);
