[0042] Working mode of the present example

[0043] Step one:

[0044] Install the gas water heater 9 to be tested to the position to be tested.

When the position sensor of the reversing mechanism 11 feeds back that it has been switched to the electronic scale 12 side, the start time, the initial mass of the electronic scale 12, the temperature value and the pressure value are recorded synchronously. During the test, the real-time mass of the electronic scale 12, the temperature value and the pressure value are recorded every 0.5 seconds; when the test is finished, the control reversing mechanism 11 is switched back to the bypass pipeline, and when the position sensor of the reversing mechanism feeds back that it has been switched to the bypass side, the stop time, the temperature value and the pressure value are recorded, and after the electronic scale 12 is stable, the final mass of the electronic scale 12 is recorded.

The key detection projects of the gas water heater 9, such as the thermal efficiency and the heat water rate, are applied.

[0053] Step six:

[0054] After the test is finished, the drain valve 13 is opened, the water in the container is discharged, the electronic scale 12 returns to the initial state, and the next test is waited.

[0055] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
