A relief valve is a type of safety valve that is used to protect equipment and systems from overpressure. It is designed to open automatically when the pressure inside a vessel or system exceeds a predetermined level, allowing excess pressure to be released and preventing damage to the equipment or system. Relief valves are commonly used in industrial processes, such as oil and gas refining, chemical manufacturing, and power generation.
There are several types of relief valves, including spring-loaded, pilot-operated, and bellows-type relief valves. Each type of valve has its own unique design and operating characteristics, but they all serve the same basic function of protecting equipment and systems from overpressure.
Direct-acting relief valves are the simplest type of relief valve and consist of a spring-loaded poppet that is held closed by a spring. When the pressure in the hydraulic system exceeds the spring force, the poppet opens and allows fluid to escape.
Pilot-operated relief valves are more complex than direct-acting relief valves and use a pilot valve to control the opening and closing of the main valve. The pilot valve is typically controlled by an external signal, such as pressure or flow rate.
