Abstract
A gas constant pressure specific heat determinator with a bypass valve comprises a flowmeter (5) and a Dewar flask (4), wherein a bypass valve (3) is arranged between a gas inlet (1) and a gas outlet (2) of the flowmeter (5), one end of bypass valve (3) as a bypass of the flowmeter (5) is communicated with the Dewar flask (2), when the Dewar flask (2) needs cooling, the bypass valve (3) should be opened, a part of gas reaches the Dewar flask (4) through the flowmeter (5), most gases reach the Dewar flask (4) directly through the bypass valve (3), a flow capacity of gases for cooling is increased, and the problem that the cooling process of original gas constant pressure specific heat determinators is slow is overcome.
Description
Technical field
The utility model relates to a kind of gas specific heat at constant pressure analyzer, particularly a kind of gas specific heat at constant pressure analyzer that has bypass valve.
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 that has bypass valve, can overcome the resistance of gas meter 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 that has bypass valve comprises flowmeter 5 and Dewar flask 4, and bypass valve 3 is installed between the air intake opening 1 of flowmeter 5 and gas outlet 2, and bypass valve 3 is connected with Dewar flask 4 as bypass one end of flowmeter 5.
The utility model is provided with bypass valve 3, opens bypass valve 3 and can accelerate to cool off Dewar flask 4.
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 that has bypass valve, comprise flowmeter 5 and Dewar flask 4, the air intake opening 1 of flowmeter 5 is connected with an end of main line and bypass valve 3, and the gas outlet 2 of flowmeter 5 is connected with the other end of bypass valve 3 and Dewar flask 4.
Principle of work of the present utility model is: when experiment, measure gas flow, close bypass valve 3, gas only enters Dewar flask 4 through flowmeter 5.
Experiment finishes, when needing cooling Dewar flask 4, open bypass valve 3, portion gas arrives Dewar flask 4 by flowmeter 5, most gases directly arrive Dewar flask 4 by bypass valve 3, increased the flow of cooling, overcome original gas specific heat at constant pressure analyzer cooling procedure problem slowly with gas.
Claims (1)
1. gas specific heat at constant pressure analyzer that has bypass valve, comprise flowmeter (5) and Dewar flask (4), it is characterized in that, between the air intake opening (1) of flowmeter (5) and gas outlet (2) bypass valve (3) is installed, bypass valve (3) is connected with Dewar flask (2) as bypass one end of flowmeter (5).
