The main purpose of safety valves is to protect the safe operation of equipment and systems. When the medium pressure in the equipment or pipeline rises above the specified value, the safety valve will automatically open and discharge the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value, thereby ensuring the safety of the equipment and system.
Safety valves are widely used in various equipment and systems that require pressure control, including boilers, pressure vessels, pipelines, petrochemical equipment, power equipment, etc. In these fields, safety valves play a vital role in ensuring the safe operation of equipment and systems.
There are various types of safety valves, including heavy hammer lever safety valves, spring-loaded safety valves, full-open safety valves, and micro-open safety valves. Each type of safety valve has its specific usage scenarios and characteristics. For example, the heavy hammer lever safety valve has a simple structure and is suitable for low pressure, high temperature, and vibration-free occasions; while the spring-loaded safety valve is compact and highly sensitive, so it is suitable for mobile equipment and fixed equipment with medium pressure pulsation.
