Controlled pressure drop valve

Abstract

A valve having stacked disks with alternate circular grooves in the faces thereof to provide a high pressure drop surface in fluid flow transverse to said grooves and ridges. The disks are circular in shape with a circular center opening to provide a central fluid opening when the disks are stacked with the center openings in register. Fluid enters the center opening and flows radially between the adjacent faces of a pair of disks to flow transversely across the continuous circular grooves and ridges.

I claim: .[.1. A valve for high pressure fluids having a vertically actuated plunger and a valve wall coacting with said plunger to form a seal therebetween, said valve wall comprising a series of stacked annular disks, having fluid flow across said disks, an annular center opening in each disk in register with the annular openings of the remaining disks to provide a cylindrical cavity to accommodate said plunger and provide a fluid inlet, each disk having a plurality of substantially circular ridges on at least one face of said disk for changing direction of fluid flow, said ridges having a V-shaped cross-section and each disk having a plurality of projections on at least one surface of said disk to space each disk from adjacent disks and a substantial opening about the inside periphery of each disk communicating with the space between said disk and an adjacent disk and a substantial opening about the outside periphery of each disk communicating with the space between said disk and an adjacent 
     
        disk and communicating with a discharge outlet of said valve..]. 2. The valve of claim .[.1.]. .Iadd.13 .Iaddend.wherein a pair of adjacent disks have opposed faces having concentric ridges on face and mating concentric 
     
     
        grooves on the opposite face. 3. The valve of claim .[.1.]. .Iadd.2 .Iaddend.wherein each disk has V-shaped concentric grooves and inverse 
     
     
        V-shaped concentric ridges interspersed between adjacent grooves. 4. The valve of claim .[.1.]. .Iadd.13 .Iaddend.wherein a pair of adjacent disks forms between opposed faces thereof an annular, continuous space having an 
     
     
        irregular radial cross-section. 5. The valve of claim .[.1.]. .Iadd.13 .Iaddend.wherein a pair of adjacent disks forms between opposed faces of an annular, continuous space of thin, radial cross-section having 
     
     
        undulating, opposed, extensive surfaces. 6. The valve of claim .[.2.]. .Iadd.13 .Iaddend.wherein .[.concentric.]. .Iadd.said .Iaddend.circular 
     
     
        ridges each have a single continuous sharp edge. 7. The valve of claim .[.1.]. .Iadd.13 .Iaddend.wherein the plurality of projections are located on one surface of each disk adjacent the outer peripheral surface of said 
     
     
        disk. 8. The valve of claim 2 wherein the ridges of one disk project into 
     
     
        the grooves of an adjacent disk. 9. The valve of claim .[.1.]. .Iadd.13 .Iaddend.wherein the ridges of said disk have crowns which are in the same 
     
     
        plane. 10. The valve of claim .[.1.]. .Iadd.13 .Iaddend.wherein a pair of adjacent disks have opposed faces having concentric ridges and concentric grooves on one face and mating concentric grooves and concentric ridges on the opposite face, the crowns of the ridges of each face being in 
     
     
        substantially the same plane. 11. The valve of claim .[.1.]. .Iadd.3 .Iaddend.wherein the depth of said V-shaped grooves increases from the innermost to the outermost groove and the height of said V-shaped ridges 
     
     
        increases from the innermost to the outermost ridge. .[.12.  The valve of claim 1 wherein the outer peripheral projections on said disk spaces said disk from another disk and overlaps the rim of an adjacent disk to prevent lateral movement thereof..]. .Iadd. 13. A valve for high pressure fluids comprising: a valve housing;   a plunger; and   a plurality of stacked annular disks mounted within said housing, each said disk comprising: an annular center opening in register with the annular center openings of the remaining disks, said annular center openings together providing a cylindrical cavity that accommodates reciprocating movement of said plunger so as to control the flow of fluid through said stacked disks;   a plurality of substantially circular ridges on at least one face of each said disk;   a plurality of projections on at least one face of each said disk, said projections overlapping the rim of an adjacent disk in order to prevent lateral movement thereof, said projections also spacing the disk from an adjacent disk so as to permit fluid flow therebetween;   a first substantial opening about the inside periphery of each said disk, said first opening communicating with the space between the disk and an adjacent disk; and   a second substantial opening about the outside periphery of each said disk, said second opening communicating with (1) said space between the disk and an adjacent disk and (2) a discharge outlet of said valve. .Iaddend. .Iadd. 14. A valve for high pressure fluids comprising:     a valve housing;   a plunger; and   a plurality of stacked annular disks mounted within said housing, each said disk comprising: an annular center opening in register with the annular center openings of the remaining disks, said annular center openings together providing a cylindrical cavity that accommodates reciprocating movement of said plunger so as to control the flow of fluid through said stacked disks;   a plurality of substantially circular ridges on at least one face of each said disk and a plurality of mating circular grooves on the opposite face of an adjacent disk, the depth of said grooves increasing from the innermost to the outermost groove and the height of said ridges increasing from the innermost to the outermost ridge;   a plurality of projections on at least one face of each said disk so as to space each disk from an adjacent disk in order to permit fluid flow therebetween;   a first substantial opening about the inside periphery of each said disk, said first opening communicating with the space between said disk and an adjacent disk; and   a second substantial opening about the outside periphery of each said disk, said second opening communicating with (1) the space between said disk and an adjacent disk and (2) a discharge outlet of said valve. .Iaddend..Iadd.     
     
     
        5.  A valve for high pressure fluids comprising: a valve housing;   a plunger; and   a plurality of stacked annular disks mounted within said housing, each said disk comprising: an annular center opening in register with the annular center openings of the remaining disks, said annular center openings together providing a cylindrical cavity that accommodates reciprocating movement of said plunger so as to control the flow of fluid through said stacked disks;   a plurality of substantially circular ridges on at least one face of each said disk and a plurality of mating circular grooves on the opposite face of an adjacent disk, the depth of said grooves increasing from the innermost to the outermost groove and the height of said ridges increasing from the innermost to the outermost ridge;   a plurality of projections on at least one face of each said disk, said projections overlapping the rim of an adjacent disk in order to prevent lateral movement thereof, said projections also spacing the disk from an adjacent disk so as to permit fluid flow therebetween;   a first substantial opening about the inside periphery of each disk, said first opening communicating with the space between said disk and an adjacent disk; and   a second substantial opening about the outside periphery of each said disk, said second opening communicating with (1) the space between said disk and an adjacent disk and (2) a discharge outlet of said valve. .Iaddend.
