The utility model is further described with reference to the following figures and detailed description.

Drawings

FIG. 1 is a schematic structural diagram of a carbon dioxide dosing precision control assembly of the present invention.

Detailed Description

The embodiment is as follows: as shown in the attached figure 1, the accurate control assembly for carbon dioxide adding comprises a carbon dioxide storage tank 2 and a carbon dioxide vaporizer 3, wherein the carbon dioxide storage tank 2 is communicated with the carbon dioxide vaporizer 3, and the side part of the carbon dioxide vaporizer 3 is sequentially provided with a temperature sensor 4, a pressure sensor 5, a flow regulating valve 6 and a flowmeter 7.

This accurate control assembly is thrown to carbon dioxide still includes PLC switch board 1, and PLC switch board 1 is connected with temperature sensor 4, pressure sensor 5, flow control valve 6, flowmeter 7 electricity.

Specifically, the flow regulating valve 6 is a regulating type ball valve with a control signal of 4-20 ma.

This accurate control assembly is thrown to carbon dioxide's theory of operation does:

1. the liquid carbon dioxide is output through a carbon dioxide storage tank 2 and then converted into gas through a carbon dioxide vaporizer 3.

2. After the carbon dioxide gas is stabilized, the thermometer pressure is detected by the temperature sensor 4 and the pressure sensor 5, and the gas state is confirmed.

3. The PLC calculates the accurate flow required by the carbon dioxide according to the relation between the pressure and the temperature

4. The carbon dioxide enters a flowmeter 7 for real-time flow detection after being regulated by a flow regulating valve 6.

5. The PLC automatically adjusts the switching degree adjusting air quantity of the flow adjusting valve 6 according to the flow detected by the flow meter 7 and conforms to the target flow all the time.

In conclusion, the system can achieve the set purpose in the automatic and accurate detection and adjustment of the gas temperature, the pressure and the flow.
