Autor: Arne Gastberg
Herausgeber: When selecting spring loaded safety valves, an accurate knowledge and consideration of the specific operating conditions are vital to ensure that these devices work reliably. As optimal resource use becomes an increasingly relevant criterion, plant owners focus particular attention on components that can be depended on absolutely – even at their physical limits. In the design of a safety valve, the existence of a backpressure must be considered in addition to the usual parameters for dimensioning. In this present report, the function of a safety valve is intended to be shown when a constant superimposed backpressure is present in the discharge and thus acts against the direction of opening of the safety valve.
