Please help calculate the safe discharge capacity of the safety valve
Thread Content
Equipment name: L-1.5 Continuous Drain Expansion Vessel. Design pressure: 0.7; Operating pressure: 0.4. Safety valve: DN50, A48Y-16C. Equipment name: 40t/h Deaeration Tower. Design pressure: 0.4; Operating pressure: 0.17. Safety valve: DN100, A48Y-16C
Insufficient parameters provided; it is necessary to know the medium, inlet and outlet inner diameters, flow rate, density, etc
The SW6 software includes the calculation of safety valves in its computations
What I’m asking about is the safe discharge volume. SW6 cannot be calculated.
The numbers you mentioned were all obtained by looking them up in tables; if I knew those numbers, I could calculate them as well.
I can tell you that the medium of the device is water and water vapor
Ensure equipment safety by releasing the same amount that is imported. This is the amount of leakage you need to calculate.
You’ve come to the wrong place; the art and design major knows how to do this
Based on the diameter of the equipment’s inlet pipe, the steam volume is calculated using the upper limit of flow rate recommended in this chart; then, the steam intake volume is determined based on the density of the steam. The exhaust volume of the safety valve must not be less than the intake volume. Even the gods won’t calculate it if you don’t provide the inlet pipe diameter.
Once the model of the safety valve is known, its discharge area is also determined; then, the discharge volume can be calculated by using the formula for calculating the discharge area of safety valves as specified in GB150.
