How Safety Valves WorkThe safety valve itself is a type of valve that is usually widely used in gas processing applications. Because when the gas experiences a pressure vessel, overpressure occurs, this valve will activate and flow the gas into the flare.
Safety valve basically has 5 main parts, namely: Adjusting Screw, Spring, Spindle, Disc and Nozzle. The working principle of the safety valve is actually quite simple where the spring is set to hold the disc sitting on the seating surface. The pressure that comes from the pressurized system will be held by the Disc. While the disc has the ability to withstand the pressure of the pressurized system depending on the setting of the spring and the strength of this spring is regulated by the adjuster screw.
If the pressure generated from the system exceeds the capacity of the spring, the disc will open and release the excess pressure. If the excess pressure has been removed then the disc will close again.
