Steam pipe diameter and regulating valve issues
Thread Content
The steam pipeline pressure is 4 kg and the flow rate is 0.5 tons per hour to heat the reactor. Is a steam pipe diameter of 40 mm suitable? Is a regulating valve spool with a hole diameter of 8 mm suitable? Which valve is better?
This should also refer to the flow rate at the valve outlet to estimate the steam pipe diameter.
The pressure difference, viscosity, and density can be used to calculate the Cv value required for a flow rate of 0.5 tons/hour, and then the pipe diameter can be known. As for whether the 8 mm hole diameter of the control valve core is enough, you cannot ask this. The Cv value of the control valve is also related to the type of the valve (butterfly valve, single-seat valve, sleeve valve, V ball) and cannot be generalized. It is more appropriate to calculate it for the manufacturer of the control valve.
