Abstract
A tester for gas specific heat at constant pressure comprises a flow meter, wherein an inlet of the flow meter is communicated with one end of an inlet valve; the other end of the inlet valve is communicated with one end of a valve and a second main pipeline; an outlet of the flow meter is communicated with one end of an outlet valve; the other end of the outlet valve is communicated with the other end of the valve and a first main pipeline; and the other end of the first main pipeline is communicated with a Dewar flask. When the gas flow is measured, the valve is closed, the outlet valve and the inlet valve are opened, and the working principle is the same as that of the conventional tester for gas specific heat at constant pressure; and when the Dewar flask is needed to be cooled down, the valve is opened, an air outlet valve and an air inlet valve are closed, gas can flow into the Dewar flask directly, the gas flow is increased, and the gas flow used for cooling is increased, thereby overcoming the problem of slow cooling process in the original tester for gas specific heat at constant pressure.
Description
Technical field
The utility model relates to a kind of analyzer, particularly a kind of gas specific heat at constant pressure analyzer.
Background technology
Gas specific heat at constant pressure analyzer is a kind of instrument that is used for the test gas specific heat at constant pressure, amount of residual heat will in the needs cooling Dewar flask of finishing using, but because the resistance of gas meter is very big, it is little to cause fan blower to send into the gas flow of Dewar flask, need to cool off for a long time, even the situation that causes Dewar flask to break owing to inhomogeneous cooling occurs.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of gas specific heat at constant pressure analyzer, can overcome the resistance of flowmeter after experiment, cools off Dewar flask fast, prevents that Dewar flask is overheated and breaks.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of gas specific heat at constant pressure analyzer, comprise flowmeter 8, it is characterized in that, the import 1 of flowmeter 8 is connected with an end of admission valve 4, the other end of admission valve 4 is connected with an end and second trunk line 7 of valve 5, the outlet 2 of flowmeter 8 is connected with an end of outlet valve 3, and the other end of outlet valve 3 is connected with the other end and first trunk line 6 of valve 5, and the other end of first trunk line 6 is connected with Dewar flask 9.
Because the utility model is provided with 3 valves, when needing cooling Dewar flask 9, can directly arrive Dewar flask 9 with gas without flowmeter 8, accelerate cooling.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in detail.
With reference to accompanying drawing, a kind of gas specific heat at constant pressure analyzer, comprise flowmeter 8, the import 1 of flowmeter 8 is connected with an end of admission valve 4, the other end of admission valve 4 is connected with an end and second trunk line 7 of valve 5, the outlet 2 of flowmeter 8 is connected with an end of outlet valve 3, and the other end of outlet valve 3 is connected with the other end and first trunk line 6 of valve 5, and the other end of first trunk line 6 is connected with Dewar flask 9.
Principle of work of the present utility model is: when experiment, measure gas flow, valve-off 5 is opened outlet valve 3, admission valve 4, and gas enters Dewar flask 9 through flowmeter 8 from air outlet valve 3, and is identical with existing gas specific heat at constant pressure analyzer principle of work; When needing cooling Dewar flask 9, open valve 5, close air outlet valve 3, gas admittance valve 4, gas directly enters Dewar flask 9 from second trunk line 7 through valve 5, first trunk line 6, obstructed inflow-rate of water turbine meter 8, can increase gas flow and increase the flow of cooling, overcome original gas specific heat at constant pressure analyzer cooling procedure problem slowly with gas.
