Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of glass instruments, and in particular to a glass instrument for measuring the saturated vapor pressure of a liquid. Background Art
[0002] At present, the glass instruments commonly used in physical and chemical laboratories for measuring the saturated vapor pressure of liquids are composed of three balls. The glass tubes have many inflection points and one end is closed. When loading samples, the sample needs to be loaded into the sample ball through the top port and the other two balls. The glass instrument has the defects of difficult loading due to atmospheric pressure, which is time-consuming and labor-intensive. Moreover, in order to ensure that about 2 / 3 of the liquid is loaded into the sample ball, the glass instrument needs to be repeatedly rotated or the liquid needs to be loaded into the sample ball with an ear cleaning ball. This process needs to be repeated many times to complete, and the operator is prone to damage the glass instrument during the loading process. In addition, it is also difficult to quickly drain the liquid out of the sample ball after the experiment is completed. In order to solve this problem, some laboratories use baking and heating methods, but this will increase the risk factor of the experiment. Utility Model Content

[0020] The glass instruments for measuring the saturated vapor pressure of liquids commonly used in current physical and chemical laboratories in the related art are all composed of three balls, and the glass tubes have many inflection points and one end is closed. When loading samples, the sample needs to be loaded into the sample loading ball through the top port and the other two balls. The glass instruments have the defects of being difficult to load samples due to atmospheric pressure during the loading process, and the process is both time-consuming and labor-intensive; moreover, in order to ensure that about 2 / 3 of the liquid is loaded into the sample loading ball, it is necessary to repeatedly rotate the glass instrument or use an ear washing ball to load the liquid into the sample loading ball. This process has the defect that it needs to be repeated many times to complete, and the operator is prone to damage the glass instrument during the loading process. In addition, it is also difficult to quickly drain the liquid out of the sample loading ball after the experiment is completed. In order to solve this problem, some laboratories use baking and heating methods, but this will increase the technical problem of the risk factor of the experiment.
[0021] In order to solve the above technical problems, Figure 1 As shown, an embodiment of the present application provides a glass apparatus for measuring the saturated vapor pressure of a liquid, including a glass apparatus main body, a first feed port 1 is provided at one end of the glass apparatus main body, a middle section of the glass apparatus main body is a condenser 2, a first feed ball 3 is provided at the other end of the glass apparatus main body, the first feed ball 3 is connected to a second feed ball 5 via a U-shaped tube 4, the second feed ball 5 is connected to a sample loading ball 7 via a three-way tube 6, and the free end of the three-way tube 6 is a second feed port 8.
[0022] The glass instrument for measuring the saturated vapor pressure of liquid in the embodiment of the present application has a simple structure and convenient and safe experimental operation, and is suitable for experimental research on the measurement of the saturated vapor pressure of liquid at different temperatures. It solves the problems of difficult sample loading, time-consuming and labor-intensive, and greatly improves the safety of the experimental process.
[0023] To facilitate understanding, the application scenarios of the embodiments of the present application are first described.
[0024] The glass apparatus provided in the embodiment of the present application can be used to measure the saturated vapor pressure of liquid. In order to measure the saturated vapor pressure of liquid, in addition to the glass apparatus used in the embodiment of the present application, some other auxiliary instruments are also required. Since the embodiment of the present application mainly improves the glass apparatus, other auxiliary instruments are not mentioned. This part is the prior art and the embodiment of the present application does not make specific limitations on this.
[0025] In a specific embodiment, reference Figure 1 The second feed port 8 is arranged directly above the sample loading ball 7.
[0026] The sample adding process is completed by directly adding the sample into the sample loading ball 7 from the second feed port 8 directly above, which greatly improves the sample adding rate, shortens the experimental time, makes the maintenance operation efficient and fast, and can also reduce the difficulty of operation and the damage rate of glass instruments.
[0027] In a specific embodiment, in order to facilitate disassembly and assembly and improve experimental efficiency, a matching sealing cover 9 is detachably provided on the second feed port 8. Exemplarily, an external thread is provided on the second feed port 8, and an internal thread matching the external thread is provided on the sealing cover 9, and the second feed port 8 is threadedly connected to the sealing cover 9. Furthermore, a sealing gasket (not shown in the figure) is also provided in the sealing cover 9. A second feed port 8 is added to the top of the sample loading ball 7 of the glass instrument, and a sealing cover 9 is detachably provided on the second feed port 8.

[0028] The sample loading and discharging process of the glass instrument for measuring the saturated vapor pressure of liquid in the embodiment of the present application is as follows:
[0029] When loading the sample, unscrew the sealing cover 9 from the second feed port 8. At this time, the sample can be added to about 2 / 3 of the sample ball 7 through the second feed port 8, and the sealing cover 9 is tightened to complete the sample loading;
[0030] When discharging samples, the sealing cover 9 is unscrewed from the second feed port 8 to pour out the sample in the sample ball 7 .
