For example, assuming that the room temperature is 20 ℃, the set temperature of the constant temperature bath medium in the container 10 is 85 ℃, the constant temperature bath medium loss in the container 10 is 625ml/h according to the statistics of the experimental results, the flow rate of the throttle valve 33 can be set to 625ml/h, but the flow rate of the throttle valve 33 can be set to 650ml/h in consideration of the variation of the ambient temperature, humidity and air pressure, so as to ensure the normal operation of the constant temperature bath control device.
According to the constant-temperature bath control device provided by the embodiment of the utility model, the valve core opening of the throttle valve is regulated, so that the amount of constant-temperature bath medium entering the communicating vessel in unit time is approximately the same as the amount of constant-temperature bath medium lost in the vessel, automatic liquid supplementing is realized, the liquid level of the constant-temperature bath medium in the vessel is always in a preset range, the labor intensity of operators is reduced, and the experimental efficiency is improved.

Specifically, when the liquid level in the container 10 drops, the liquid level in the communicating vessel 20 also drops, and when the liquid level in the communicating vessel 20 drops to the position of the first liquid level sensor 21, the first liquid level sensor 21 sends a signal to the controller 60, the controller 60 controls the electromagnetic valve 34 to be electrified and sucked to open, and the constant-temperature bath medium in the liquid replenishing container 31 enters the communicating vessel 20 through the electromagnetic valve 34 and the throttle valve 33; when the liquid level in the communicating vessel 20 rises to the position of the second liquid level sensor 22, at this time, the liquid level in the vessel 10 is at the set position, the second liquid level sensor 22 sends a signal to the controller 60, the controller 60 controls the electromagnetic valve 34 to be powered off and closed, and the constant-temperature bath medium in the fluid replacement vessel 31 does not enter the communicating vessel 20 any more. Further, in the present embodiment, the controller 60 controls the valve opening of the throttle valve 33 to adjust the flow rate of the constant temperature bath medium flowing through the throttle valve 33, so as to avoid the excessive flow rate and impact, and facilitate accurate control of the liquid level in the communicating vessel 20.

Specifically, the robot 40 is used to hold the object 100 for performing experiments. When the liquid level in the communicating vessel 20 is located at the position of the first liquid level sensor 21, the manipulator 40 is holding the object 100 for experiment, the controller 60 does not energize the electromagnetic valve 34, and the electromagnetic valve 34 is still in a power-off state, so as to avoid temperature disturbance caused by the constant temperature bath medium entering the container 10, and further influence the experiment result. After the manipulator 40 clamps the object 100 away from the container 10, the controller 60 controls the solenoid valve 34 to be energized again, so that the solenoid valve 34 is attracted to supplement the fluid to the communicating vessel 20.
Further, the controller 60 is further configured to control the manipulator 40 to clamp the object 100 from moving into the container 10 when the electromagnetic valve 34 is energized and the fluid infusion container 31 supplements the constant-temperature bath medium into the communicating vessel 20, so as to avoid the influence of temperature change caused by fluid infusion on the experimental result of the object 100.
