Overpressure relief devices play a vital role in the active safety measures of high-pressure hydrogen storage systems. These devices can automatically start when the system pressure exceeds the safe range, and reduce the pressure by discharging part of the medium, thereby protecting the equipment and system from damage.
Overpressure relief devices typically include safety valves, bursting discs, and combinations thereof. As a reclosing pressure relief device, the safety valve can automatically open when the pressure exceeds the set value, release the excess pressure, and automatically close after the pressure is reduced to restore the normal operation of the system. The bursting disc is a non-reclosing pressure relief device. Once the pressure exceeds its design limit, the bursting disc will break instantly to achieve rapid pressure relief, but a new bursting disc needs to be replaced afterwards.
When selecting an overpressure relief device, it must be ensured that its rated discharge volume is greater than or equal to the safe discharge volume of the container to ensure that the system pressure can be effectively reduced under overpressure conditions. This design principle is based on rigorous calculations and testing to ensure the reliability and safety of the device under extreme conditions.
In addition, the installation and maintenance of the overpressure relief device is also an important link to ensure the safety of the system. The correct installation position, appropriate discharge area and regular inspection and maintenance are the keys to ensure the effective operation of the device.
In summary, the overpressure relief device is one of the indispensable active safety measures for the high-pressure hydrogen storage system. Through its precise design and reliable operation, it provides a solid guarantee for the safe and stable operation of the system.
