Can the energy storage device work as a relief valve

What is a main relieving valve?

Main relieving Valve: that part of a pilot operated pressure relief device through which the rated flow occurs during relief. lift lever: a device to apply an external force to the stem of a pressure relief valve to manually operate the valve at some pressure below the set pressure.

How does a pressure relief valve function?

A pressure relief valve works by opening a spring-loaded mechanism when pressure rises above a pre-determined setting. This allows pressure to be relieved through the valve, as air is exhausted from the system. Once the pressure falls back to its pre-set level, the valve closes again.

What is a relief valve?

A relief valve is a device designed to protect compressed air systems from over-pressurization. It works by releasing excess pressure when the pressure acts against the valve seat and generates a force that opens the valve against spring tension.

Does a storage tank need a pressure relief valve?

In many storage tank applications, a pressure relief valve is required for emergency overpressure relief. This contingency is often necessary due to an external source of heat, such as a fire, that could boil the liquid contents.

Where can back pressure exist in a pressure relief valve?

Back pressure can exist in any location that is downstream from the actual discharge area of a pressure relief valve. This pressure can be due to piping causing resistance to flow, pressures from other equipment discharging to a common header system, or from a flashing fluid being relieved.

What is an emergency pressure relief valve?

An emergency pressure relief valve is a tank hatch with a hinged cover, also known as a “manway”. The cover has a calibrated weight, moment arm, and possibly a counterweight to provide the required set pressure. These devices can be considered to provide additional capacity in situations where extra pressure relief is needed.
