Abstract
Abstract A device for mixing viscous fluids with water comprising a rectangular block containing a pre-mixing chamber, a center section fitted with a bevelled double acting valve capable of restricting fluid flow in two distinct directions, an outlet chamber and recycling means for thoroughly mixing the viscous fluids with the water. The mixing device is able to balance both low and high back pressures, eliminate cavitation and deliver a mixture of viscous fluid and water without serious degradation of the components of the viscous fluids.
