Bladder & Gas Valve Nuclear Safety

Bladder & Gas Valve Nuclear Safety

Bladder

• Function: The bladder is an expandable component that stores pressurized gas. It is usually made of rubber or a similar material and is placed inside a metal or composite shell.

• Operation: When hydraulic fluid enters the accumulator, it compresses the gas in the bladder. When the fluid is needed, the compressed gas expands, pushing the fluid back into the hydraulic circuit.

Gas Valve

• Function: The gas valve is a component that controls the flow of gas into and out of the bladder.

• Operation: It typically includes a poppet valve that prevents the bladder from extruding through the port when the bladder is fully expanded. The valve ensures that the gas remains separated from the hydraulic fluid and maintains the system’s pressure.

These components work together to maintain pressure stability in hydraulic systems, ensuring efficient operation and energy savings.
