How to choose the pressure resistance and temperature resistance of the valve?
A The selection of pressure and temperature resistance for valves requires consideration of the pressure and temperature range of the medium. Typically, suitable valves can be chosen based on factors such as valve material, sealing structure, and design standards.
How to determine the size of the valve?
A
Determining valve size usually requires consideration of factors such as pipeline size, flow requirements, pressure, etc. The appropriate size can be selected based on parameters such as flow coefficient (Cv value) and pressure.
What are the common types of valves and how to distinguish their application scenarios?
A Common types of valves include ball valves, gate valves, butterfly valves, check valves, etc. Their application scenarios depend on factors such as medium, pressure, and temperature. For example, ball valves are suitable for situations that require quick opening and closing, gate valves are suitable for situations that require flow regulation, butterfly valves are suitable for situations with high flow rates, and check valves are suitable for situations that prevent medium backflow.
