Will the water not flow if the drain valve is chosen to be too large? Is there any way?

By size, it should refer to the displacement volume; normally, this shouldn’t make a difference. If the displacement is high, the opening/closing frequency of the internal valve seats might be higher, and over time the valve seats could fail or have a poorer sealing effect. Paying a little attention to this should be sufficient

Around 0.3 MPa, with a back pressure of around 5 meters behind the valve as well as in front of it

Thank you! In other words, there is no atmospheric pressure drain valve?

It shouldn’t happen; rather, the frequency of activation should decrease. The steam traps in our distillation towers are selected based on the maximum possible load, but in practice they never reach that maximum level of operation

If the drain valve is too large, it may cause air leakage; I’ve encountered this issue before, with buckets that were hung upside down. I’m not sure what type of bucket you have

It will definitely leak. Moreover, the steam trap itself isn’t 100% airtight; even if you choose one that’s suitable, leaks will still occur. Steam traps are usually selected to be larger in size, about three times the amount of condensate produced

Is it justified that it is 3 times the amount of condensate water? I’m worried that if I choose a size that’s too large, will the condensation water be detected?

I’m worried that if I choose a too large size, the condensate water won’t be able to drain properly

There’s no official source for this; it’s experience shared by a friend who specializes in steam, and it’s quite accurate. I’ll check where this information comes from and get back to you
