Calculation of the discharge volume of a safety valve
Thread Content
I would like to ask the professionals in the field of instrumentation: How is the orifice area of a PSV calculated? Is there a standard formula, or does it depend on the manufacturer? Thank you.
API 520 provides detailed regulations for the calculation and selection of safety valves; there are standard formulas for calculating the bore diameter. However, the discharge coefficients used in safety valves differ significantly between domestic and foreign products. The coefficients chosen by domestic safety valve manufacturers are lower than those used abroad, due to factors such as manufacturing processes.
There is a lot of information on the forum regarding the calculation of safety valves; it might be more effective for the original poster to review this information first before asking specific questions.
We also conducted the calculations in accordance with the Pressure Vessel Inspection Regulations. This post has a good rating; go take a look: http://bbs.hcbbs.com/viewthread.php?tid=4192&highlight=%B0%B2%C8%AB%2B%BC%C6%CB%E3
I am extremely grateful for everyone’s selfless help, and I hope to receive more support from you in the future
I was just trying to calculate the discharge rate of the safety valve when I came across the original poster’s post. Thank you to everyone who provided information – it was very helpful:lol
