Abstract
The utility model relates to a gas characteristic law instrument, comprising a pressurized capsule (15), a transparent container (6), an air cylinder (4), and a piston (5). The inner spaces of the air cylinder (4) and the transparent container (6) are mutually isolated, and the pressurized capsule (15) is communicated with the air cylinder (4). The utility model is used for verifying the physical properties of gases in teaching, and has the advantages of high test accuracy, simple structure and easy production when compared with the prior art.
Description
The utility model relates to the teaching and experiment equipment of checking gas physical property, especially a kind of gas property law instrument that is contained in transparent vessel, rain glass and air drum that comprises.
Existing gas property law instrument, as the applicant at " the gas property law instrument " of first to file (patent announcement number: CN2311813Y; The day for announcing: on March 24th, 1999), the lower end of its air drum piston is connected with interior of the container, and to the air drum inner carrier acting force be to be pressed into airtight internal tank by medium in the outer capsule of container to realize.The gas property law instrument of this structure still can produce considerable influence to the test accuracy: on the one hand, because medium is pressed into the interior medium temperature of closed container is produced than macromutation in the capsule, the temperature that the medium in airtight container measures can not reflect the temperature of test gas in the air drum exactly; On the other hand, because capsule is communicated with closed container, the water that is used as pressure medium is understood be converted into steam owing to piston up-down sticks to the air drum inwall, makes tested gas become saturated gas and can not be used for testing as ideal gas.
The purpose of this utility model provides a kind ofly can accurately measure tested gas temperature, can effectively prevent the gas property law instrument of tested gas vapor content again.
For achieving the above object, the scheme that the utility model adopts is: it includes pressurization capsule, transparent vessel, be contained in the air drum in the transparent vessel and be contained in the interior piston of air drum, it is characterized in that: the inner space of described air drum and the inner space of transparent vessel are isolated, and described pressurization capsule is communicated with air drum.
The lower end of above-mentioned air drum can be isolated with the inner space of the inner space of described air drum and transparent vessel by rubber plug, and described pressurization capsule is contained in the below of described rubber plug, and this pressurization capsule passes described rubber plug by pipe and is communicated with air drum; The top of above-mentioned transparent vessel can be equiped with container cover, and well heater can be installed in its bottom.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, tested gas thermometry is accurate.Because the inner space of air drum and the inner space of transparent vessel are isolated, the pressurization capsule directly is communicated with air drum, therefore, medium in the pressurization capsule is pressed into the relative prior art of air drum lower part of piston, temperature effect to the tested gas in air drum inside can reduce greatly, thereby guarantees the accuracy of tested gas thermometry; In addition, the height of air drum has been improved in the below that the pressurization capsule is located at air drum, is convenient to the student viewing pilot demonstration on the classroom.
2, can prevent the variation of tested gas vapor content.Because the inner space of air drum and the inner space of transparent vessel are isolated, the pressurization capsule directly is communicated with air drum, therefore, the pressure medium in thermostatic medium in the transparent vessel and the pressurization capsule can be served as by two media respectively.Like this, when using cheap water as thermostatic medium, can use non-drying oil liquid as pressure medium again, non-drying oil is non-volatility under normal conditions.Therefore, can prevent that volatile pressure medium from sticking to the air drum inwall and the phenomenon of gas, liquid two inversion of phases takes place and cause the content of tested gas vapor.
3, simple in structure, easy to manufacture.Because the inner space of air drum and the inner space of transparent vessel are isolated, the pressurization capsule directly is communicated with air drum, therefore, the unnecessary closed container of making of transparent vessel, thereby more simpler than existing gas property law instrument structure, manufacturing is more prone to.
The utility model is described in further detail below in conjunction with the accompanying drawing example:
Fig. 1 is a structural representation of the present utility model.
In the example shown in Figure 1, the utility model has a transparent vessel 6, well heater 12 is equipped with in the bottom of transparent vessel 6, the top is provided with container cover 2, connect with rain glass 1 in the mode that is threaded at container cover 2 middle parts, the air hole of rain glass 1 communicates with the air drum 4 that the top is bonded under the container cover 2, also is provided with intake-outlet 3 and thermometer 11 on the container cover 2.Surface at air drum 4 is provided with scale, the piston 5 that can fluctuate wherein is housed, rubber plug 13 is equipped with in the lower end of air drum 4, be provided with the pipe 7 that is communicated with air drum 4 and is contained in the pressurization capsule 15 in the support 9 in the rubber plug 13, at support 9 pressure regulation swing arm 10 is housed also, the bottom of pressurization capsule 15 is provided with gateway 8.
The utility model can make pressure medium be full of pressurization capsule 15 earlier by adding non-drying oil as pressure medium from gateway 8 in use, adds entry as thermostatic medium from intake-outlet 3 then, connects the power supply of well heater 12 on two binding posts 14.During test, the power supply of connecting well heater 12 makes the water in the transparent vessel 6 reach also constant on design temperature, be pressed into the bottom of air drum 4 by the rotation pressure regulation swing arm 10 interior grease of capsule 15 that will pressurize by pipe 7, piston 5 is moved upward to the tested gas boosting on piston 5 tops.Can obtain temperature, pressure and the volume of tested gas under the different conditions by the scale on air drum 4, thermometer 11 and the rain glass 1.
