Final answer:
The cylinder valve cap is used to protect the gas outlet valve and the pressure relief valve from operational or accidental damage.
Explanation:
The cylinder valve cap is used to protect the gas outlet valve and the pressure relief valve from operational or accidental damage.
When the gas in the cylinder expands, it exerts pressure on the internal walls. By using a cylinder valve cap with an air gap, it allows the gas to expand and contract without stressing the container. This prevents the risk of bursting the container or leaking gas.
