What is a Safety Valve? Introduction to Functions and Working Principles

secureluokai 七月 3, 2026

A safety valve is a commonly used automatic pressure relief protection device in industry. It is mainly applied to pressure vessels, pipelines and various pressure-bearing equipment, which effectively prevents equipment damage caused by system overpressure, avoids potential safety hazards, and ensures stable and safe operation of equipment.
The closing member of the safety valve remains normally closed and sealed under external force under normal operating conditions without affecting the normal operation of the equipment. When the medium pressure inside the equipment or pipeline rises abnormally and exceeds the set safety pressure, the valve will open automatically to discharge the medium and relieve pressure quickly, bringing the system pressure back to the safe range.
As a type of automatic valve, the safety valve operates without manual intervention and opens and closes automatically according to pressure changes with sensitive response and high reliability. It is an essential safety protection accessory for boilers, pressure vessels, pressure pipelines and other equipment, playing a key overpressure protection role in industrial safety production.
