How to select an emergency relief valve?
With the process parameters available, a selection is made based on them. Generally, design institutes determine the diameter of the emergency relief valve based on the discharge volume, and then consider the discharge pressure as well
Calculated by the design department based on the process parameters of the designed device
Material properties, operating parameters, process requirements. Wait, there are relevant calculation examples online
This falls under the scope of the technical process package, and is determined by the Technical Center based on the properties of the materials and the process conditions.
This is determined based on the requirements of the manufacturing process, primarily to meet sudden discharge demands and prevent dangers such as overpressure explosions.
Generally, the design institute will make the selection. Unless there are changes
The safety valve specifications include formulas for calculating the discharge volume.
Refer to the calculation of safety discharge capacity in Part 1: General Requirements of GB 150.1-2011 for Pressure Vessels, and use these calculations as a guide for selection.
