Fremgangsmåde til at konstruere en strømningsstyringsventil og en strømningsstyringsventil

摘要

The present invention relates to a method for designing characteristics of a flow control valve arrangement to adapt it to a characteristics of a process which the valve arrangement is interacting with. The method comprises the steps of: designing a first hole pattern in at least one first element and a second hole pattern in at least one second element of the valve arrangement, wherein geometries of the hole patterns are designed such that a desired valve characteristics is achieved; wherein the first and second element are arranged such that the throughput area can be varied by relative displacements of the elements in at least two substantially orthogonal directions in dependence of at least two parameters of the process. The invention also relates to valve arrangement designed according to the method, which valve arrangement may be used, for example, in a heat exchanger.
