Abstract

A mixer for a fluid flow in a pipe connection, especially for homogenizing a multiphase flow, has a housing to be inserted in the pipe connection for the fluid to flow through. In the housing there are at least one and preferably two or more adjoining and individually displaceable regulating elements having cooperating wall portions with flow passages. At an upstream side radial flow passages cause the fluid to converge into a central chamber. In the cooperating wall portions, a number of flow channels can be aligned or misaligned with one another and/or the inlet and outlet openings to regulate and control flow by movement of the regulating elements. The regulating elements also define a full cross-section opening at 90.degree. to the flow passages, which can clear the passage between the inlet and outlet for passage of a pipe pig.
