Answer :
Final answer:
A safety valve serves to protect power units from excessive pressure. It is designed to open at a pressure slightly higher than the normal system operating pressure, thus preventing system damage or failure. Safety valves are widely used in engineering fields like power generation, oil and gas, industrial heating systems.
Explanation:
A safety valve is a device in a power unit that protects the equipment from excessive pressure. In normal operations, system pressure is controlled by a relief valve. However, if the relief valve fails, the pressure could exceed its designed limit, causing potential damage or failure to the system. That's where the safety valve comes into play. The safety valve is designed to open at a pressure slightly higher than the normal system pressure, thereby preventing damage due to b
Safety valves are critical components in the engineering field, especially in fields where high pressure systems are commonly used, such as power generation, oil and gas, and industrial heating systems.
