What does the safety valve discharge coefficient mean?
1 Answers
Safety valve discharge coefficient is the ratio of the actual discharge to the theoretical discharge of a safety valve, which is an important performance indicator of the safety valve, also known as the safety valve relief coefficient. Actual discharge of the safety valve: The actual discharge is the measured medium release quantity at the rated discharge pressure. Rated discharge of the safety valve: The rated discharge refers to the portion of the actual discharge that is allowed as the applicable benchmark for the safety valve. Theoretical discharge of the safety valve: The theoretical discharge is the calculated discharge of an ideal nozzle with a flow channel cross-sectional area equal to the flow channel area of the safety valve. Rated discharge coefficient of the safety valve: The rated discharge coefficient of the safety valve is the product of the discharge coefficient and the reduction coefficient (the reduction coefficient is generally taken as 0.9).
