Fluid pressure reduction device
View Patent ↗A fluid pressure reduction device comprises a plurality of stacked disks having a perimeter and a hollow center aligned along a longitudinal axis. Each disk has at least one flow path extending between the hollow center and the perimeter, the flow path including an inlet section, an outlet section, and an intermediate section extending between the inlet and outlet sections. Each flow path intermediate section includes a pressure reducing structure and a recovery zone positioned immediately downstream of the pressure reducing structure.
1. A method of assembling a fluid pressure reduction device, comprising:
forming a plurality of disks having at least one flow path extending between a hollow center and a perimeter of the disk, each flow path including an inlet section, an outlet section, and an intermediate section extending between the inlet and outlet sections, the flow path dividing the disk into at least first and second blank portions, each disk further including a first bridge portion extending between the first and second blank portions;
stacking the disks along an axis;
securing the stacked disks together to form a stacked disk assembly;
removing the first bridge portion of each disk in the stacked disk assembly.
2. The method of claim 1 , in which the first bridge portion comprises an inner ring portion extending about the interior portion of the disk.
3. The method of claim 1 , in which the first bridge portion comprises an outer ring portion extending about the perimeter of the disk.
4. The method of claim 1 , in which the first bridge portion comprises a tab extending between the first and second blank portions.
5. The method of claim 1 , in which the disk further includes a second bridge portion, and in which the method further comprises the step of removing the second bridge portion of each disk in the stacked disk assembly.
6. The method of claim 5 , in which the first bridge portion comprises an inner ring portion extending about the interior portion of the disk, and the second disk portion comprises an outer ring portion extending about the perimeter of the disk.
7. The method of claim 5 , in which the first and second bridge portions comprise first and second tabs extending between adjacent blank portions.
