The pressure relief valve is often referred to as a safety valve or a safety relief valve. It automatically opens and closes according to the working pressure of the pressure system and is generally installed on the equipment or pipeline of a closed system to protect the system's safety. When the pressure inside the equipment or pipeline exceeds the set pressure of the pressure relief valve, it automatically opens to ensure that the pressure of the medium inside the equipment and pipeline is below the set pressure, protect the normal operation of the equipment and pipeline, prevent accidents, and reduce losses.
The pressure relief valve is commonly used in a variety of industries, including oil and gas, chemical processing, power generation, and manufacturing. Its primary application is to protect pressure vessels, pipelines, and other equipment from overpressure situations that could result in explosions, fires, or other hazards. In the oil and gas industry, pressure relief valves are used to protect wellheads, pipelines, and storage tanks from excessive pressure. In chemical processing plants, they are used to protect reactors, distillation columns, and other equipment from overpressure caused by chemical reactions or other process upsets. In power generation plants, pressure relief valves are used to protect boilers, turbines, and other equipment from overpressure caused by steam or other fluids. The widespread application of pressure relief valves in various industries highlights their importance in maintaining safe and efficient operations.
