Mixing valve with adjustable regulating elements and central chamber
First Claim
1. Mixer for mixing the components of a fluid flow in a pipe connection, comprising a housing adapted to be inserted in the pipe connection for permitting fluid to flow therethrough in a flow direction, said housing comprising an inlet opening and an outlet opening each having a cross-sectional area, wherein the housing is provided with a first moveable regulating element formed with a through-bore and partially enclosing a central chamber, the first regulating element having a first wall portion directed in a normal operating position substantially toward the inlet opening on an upstream side of said housing and a second wall portion directed in said normal operating position substantially toward the outlet opening on a downstream side of said housing, said first wall portion being provided with a plurality of ingoing flow channels, and said second wall portion being provided with a plurality of outgoing flow channels and wherein the through-bore has a cross-sectional area corresponding substantially to the cross-sectional area of each of the inlet and outlet openings, said flow channels each having a substantially smaller cross-sectional area than the cross-sectional area of each of the inlet and outlet openings respectively, and wherein the first regulating element is moveable in relation to said housing for selectively orienting part of the ingoing and outgoing flow channels toward the inlet opening and the outlet opening, respectively, and part of said flow channels toward the housing, whereby mixing is effected in the central chamber, between the inlet opening and the outlet opening and wherein the first regulating element is selectively movable to align the through-bore with the inlet and outlet openings for a substantially free through-flow without mixing effect.

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° to the flow passages, which can clear the passage between the inlet and outlet for passage of a pipe pig.

- 1. Mixer for mixing the components of a fluid flow in a pipe connection, comprising a housing adapted to be inserted in the pipe connection for permitting fluid to flow therethrough in a flow direction, said housing comprising an inlet opening and an outlet opening each having a cross-sectional area, wherein the housing is provided with a first moveable regulating element formed with a through-bore and partially enclosing a central chamber, the first regulating element having a first wall portion directed in a normal operating position substantially toward the inlet opening on an upstream side of said housing and a second wall portion directed in said normal operating position substantially toward the outlet opening on a downstream side of said housing, said first wall portion being provided with a plurality of ingoing flow channels, and said second wall portion being provided with a plurality of outgoing flow channels and wherein the through-bore has a cross-sectional area corresponding substantially to the cross-sectional area of each of the inlet and outlet openings, said flow channels each having a substantially smaller cross-sectional area than the cross-sectional area of each of the inlet and outlet openings respectively, and wherein the first regulating element is moveable in relation to said housing for selectively orienting part of the ingoing and outgoing flow channels toward the inlet opening and the outlet opening, respectively, and part of said flow channels toward the housing, whereby mixing is effected in the central chamber, between the inlet opening and the outlet opening and wherein the first regulating element is selectively movable to align the through-bore with the inlet and outlet openings for a substantially free through-flow without mixing effect.
- 10. Mixer for mixing the components of a fluid flow in a pipe connection, comprising a housing adapted to be inserted in the pipe connection for permitting fluid to flow therethrough in a flow direction, said housing comprising an inlet opening and an outlet opening each having a cross-sectional area, wherein the housing is provided with at least first and second regulating elements partially enclosing a central chamber, each of said first and second regulating elements having a first wall portion directed in a normal operating position substantially toward the inlet opening on an upstream side of said housing and a second wall portion directed in said normal operating position substantially toward the outlet opening on a downstream side of said housing, said first and second wall portions being provided with a plurality of ingoing and outgoing flow channels, respectively, said flow channels each having a substantially smaller cross-sectional area than the cross-sectional area of the inlet and outlet openings respectively, the first and second regulating elements being moveable in relation to said housing for selectively orienting part of the ingoing and outgoing flow channels toward the inlet opening and the outlet opening, respectively and individually mutually displaceable laterally relative to the fluid flow for selectively opening and closing serial flow channels defined by the regulating elements and passing from the inlet opening, through selectively aligned ones of the ingoing flow channels of the regulating elements, through the central chamber, and through selectively aligned ones of the outgoing flow channels of the regulating elements to the outlet opening, whereby mixing is effected in the central chamber, between the inlet opening and the outlet opening.
