Gas flow control in the regeneration system of glove box laboratory equipment is a key step to ensure a stable gas environment during experiments or production. The following is a detailed explanation of the gas flow control performed by the regenerative system: In glove box experiments or production, precise gas flow control is essential to maintain a pure and stable environment in the glove box. Improper gas flow can lead to fluctuations in gas composition, affecting the accuracy of experimental or production results.

Method of gas flow control

► Pressure reducing valve regulation

Pressure reducing valve is the key equipment for controlling gas flow. By adjusting the opening of the pressure reducing valve, you can change the flow of gas into the glove box.

In the regeneration system, two pressure reducing valves of the main table and the secondary table are usually set up to meet the needs of different flow control.

► Flow meter monitoring

The flowmeter is used to monitor the gas flow in real time to ensure that the gas flow is within the set range.

Common flowmeters are gas float flowmeters, which can accurately measure the flow of gas and feed the data back to the control system.

► Automatic control system adjustment

Regenerative systems are usually equipped with a PLC or other type of control system to automatically regulate the gas flow.

The control system will automatically adjust the opening of the pressure reducing valve according to the preset gas flow parameters and the real-time monitoring gas flow data to maintain the stability of the gas flow.

► Manual adjustment and intervention

In some cases, the operator may need to manually adjust the gas flow. For example, during the initial or final stages of the regeneration process, it may be necessary to manually adjust the opening of the pressure reducing valve to accommodate different flow requirements.

In addition, if the flow meter display is abnormal or the control system fails, the operator also needs to manually intervene in time to ensure the stability of the gas flow.

Gas pressure control in the regeneration system of glove box laboratory equipment is an important link to ensure the stability and safety of the experimental environment. The following is a detailed explanation of how the gas pressure is controlled in the regeneration system:

► The importance of gas pressure control

In glove box experiments, the stable control of gas pressure is essential to maintain the purity of the box environment and prevent external contamination. Improper gas pressure may lead to the infiltration of external air and affect the accuracy of experimental results.

► Method of gas pressure control

1) Pressure reducing valve regulation: Pressure reducing valve is the key equipment to control gas pressure. The pressure of gas flowing into the glove box can be changed by adjusting the opening of the pressure reducing valve.

Regenerative systems are usually equipped with high-precision pressure reducing valves to ensure accurate control of gas pressure.

2) Pressure sensor monitoring: The pressure sensor is used to monitor the gas pressure in the glove compartment in real time.

When the pressure sensor detects that the pressure in the glove box deviates from the set value, it sends a signal to the control system.

3) Automatic control system adjustment: Regenerative systems are usually equipped with advanced control systems such as PLC (Programmable logic Controller).

The control system automatically adjusts the opening of the pressure reducing valve according to the signal of the pressure sensor to maintain the stability of the gas pressure in the glove box.

4) Manual adjustment and intervention: In some cases, the operator may need to manually adjust the gas pressure. For example, before or at the end of the experiment, it may be necessary to manually adjust the opening of the pressure reducing valve to accommodate different pressure requirements.

If the control system fails or the pressure needs to be adjusted quickly, the operator can manually intervene to ensure the gas pressure is stable.

► Precautions for gas pressure control

1) Periodic calibration: Equipment such as pressure sensors and pressure reducing valves require regular calibration to ensure the accuracy of their measurements and adjustments.

The calibration period should be determined according to the frequency and accuracy requirements of the equipment.

2) Maintenance and cleaning: Equipment such as pressure reducing valves and pressure sensors can become contaminated or clogged during use, so regular maintenance and cleaning are required.

When maintaining and cleaning the equipment, follow the operating instructions and safe operation procedures.

3) Safe operation: When performing gas pressure control, operators should wear appropriate personal protective equipment and follow safe operating procedures.

If a gas leak or abnormal situation is found, stop the operation immediately and seek professional help.

4) Pressure range setting: According to the specific requirements of the experiment, the gas pressure range of the glove box is reasonably set.

Avoid setting too high a pressure to prevent damage to the glove box or safety incidents.

5) Monitoring and alarm: The regeneration system shall be equipped with gas pressure monitoring and alarm functions.

When the gas pressure exceeds the set range, the system will automatically trigger an alarm to remind the operator to take timely measures to adjust.
