What Is The Function Of Safety Valves?

All fluids, whether stationary or flowing, have pressure associated with them. Each device has an allowable pressure value that it can withstand without breaking. Typically, this safety limit is provided based on design pressure.

Explosions can cause damage to the environment. It can cause loss of life and property.
Therefore, it is an important task to install a safety valve in the equipment. When the pressure in the container exceeds a certain value, the valve is automatically opened by the pressure of the medium itself, and a certain amount of medium is quickly discharged.

When the pressure in the container drops to the allowable value, the valve will automatically close again, so that the pressure in the container is always lower than the upper limit of the allowable pressure, and the accident that may occur due to overpressure is automatically prevented.

Therefore, the safety valve is also called the last protection device of the pressure vessel. The constant pressure of the safety valve is generally 1.0±5 to 1.10 times the working pressure.

1. When the pressure exceeds the specified pressure, the pressure relief function can be automatically activated to prevent overpressure damage to equipment and pipelines, and the control pressure does not exceed the specified value.

2. When the medium pressure in the equipment or pipeline rises above the specified value, it is a special valve that protects personal safety and equipment operation by discharging the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value.
Safety valves are used in automatic valves, mainly in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation.
