Abstract
A homogenizer valve includes two or more pressurized, movable valve cones, two or more valve seats and a valve housing which surrounds the valve cones and the valve seats. The valve cones and the valve seats are disposed so that throttles occur between them, which constitute homogenization gaps, which have a gap height h. The homogenization gaps are disposed at an angle in relation to the horizontal plane. The homogenizer valve is intended to be used in existing homogenizers and has been particularly produced to be able to obtain an efficient homogenization for liquids which are processed at a lower pressure and with a greater flow, such as, for example, pasteurized milk.
Claims17
A homogenizer valve used to homogenize liquid comprising:
- an axially extending valve housing having an interior, an inlet into which the liquid to be homogenized is introduced and an outlet from which the liquid exits the housing;
- a plurality of axially adjacent valve seats in the interior of the housing;
- a plurality of movable valve cones in the interior of the housing, the plurality of valve cones being mounted on a common movable rod so that movement of the rod results in corresponding movement of all of the plurality of valve cones, each valve cone cooperating with a respective one of the valve seats so that a respective throttle occurs between each valve cone and the respective valve seat, with each throttle constituting a homogenization gap so that a total number of homogenization gaps is equal to a total number of valve seats and so the total number of homogenization gaps is also equal to a total number of valve cones;
- each of the plurality of valve cones possessing an outer dimension greater than an inner dimension of the cooperating valve seat so that each of the plurality of valve cones and the associated valve seat radially overlap one another to define the homogenization gap;
- and
- wherein the common movable rod is a threaded rod and all of the plurality of valve cones threadably engage the threaded rod centrally disposed in the interior of the valve housing.
A homogenizer valve comprising
- a plurality of pressurized, movable valve cones;
- a plurality of valve seats;
- a valve housing surrounding the valve cones and the valve seats;
- each of the valve cones being associated with a respective one of the valve seats so that a throttle occurs between each valve cone and the associated valve seat, constituting a homogenization gap;
- each of the valve cones possessing an outer dimension greater than an inner dimension of the associated valve seat so that each valve cone and the associated valve seat radially overlap one another to define the homogenization gap;
- wherein all of the plurality of pressurized, movable valve cones are identical to each other;
- and
- wherein all of the plurality of valve seats are identical to each other.
