The working principle of the pressure regulating and metering skids is mainly to adjust the gas pressure through a series of devices to meet the specific pressure requirements of downstream equipment or users.
1. Main components and functions
Pressure regulator: The core component controls the gas flow by automatically adjusting the valve opening to achieve pressure regulation. When the downstream pressure increases, the pressure regulator will reduce the valve opening, reduce the gas flow, and reduce the pressure; conversely, when the downstream pressure decreases, the pressure regulator will increase the valve opening, increase the gas flow, and increase the pressure.
Filter: Filter impurities in the gas to prevent impurities from entering the pressure regulator and downstream equipment and affecting the normal operation of the equipment.
Safety shut-off valve: When the system has abnormal conditions, such as too high or too low outlet pressure, pipeline leakage, etc., quickly cut off the gas source to protect the safety of downstream equipment and personnel.
Monitoring pressure regulator: As a backup pressure regulator, it automatically starts to operate when the main pressure regulator fails to ensure a continuous and stable supply of gas.
2. Working process
After the gas enters the pressure regulating skid, it first passes through the filter to remove impurities.
Then it enters the pressure regulator, which automatically adjusts the valve opening according to the change of downstream pressure. If the downstream pressure is lower than the set value, the pressure regulator will increase the valve opening, increase the gas flow, and increase the pressure; if the downstream pressure is higher than the set value, the pressure regulator will reduce the valve opening, reduce the gas flow, and reduce the pressure.
The safety shut-off valve monitors system pressure and other parameters in real time, and will quickly cut off the gas source once an abnormality is found.
The monitoring pressure regulator is installed in parallel with the main pressure regulator. When the main pressure regulator fails, the monitoring pressure regulator will automatically start to ensure the continuous supply of gas.
In short, the pressure regulating and metering skid achieves precise regulation and safe control of gas pressure through the coordinated work of various components, ensuring that downstream equipment or users can obtain a stable and reliable gas supply.
