A fluid control valve for high pressure surges, that has a controlled pressure drop box inside, arranged on a block seat and through whose core a cylindrical plug can be moved. The box is formed by a number of disks grooved on both sides, fluid flows through the grooves. The grooves are arranged in a spiral, curved clockwise or counterclockwise and crossways to the grooves of the adjacent disks, forming a number of chambers at the intersections between the contact faces of two side-by-side disks. A dynamic mixture of the incoming fluid veins through each groove is produced in each of the chambers, with the ensuing creation of local turbulence and loss in kinetic energy as heat prior to evacuation through the protruding course of the outlet grooves. The successive chambers in the course of the grooves are arranged in tiered annular spaces of gradual and controlled pressure loss. |

1. A fluid control valve for high pressure surges, of the type comprising:
a valve body with a lid a disk holder and a plug that can be gradually moved axially inside a setting box for equalizing and regulating the pressure surge, having a block seat on the bottom of the box, as an end position of the plug, wherein the box comprises a stack of disks spirally grooved from the inside out, forming a number of fluid passageways in said grooves; wherein the existing grooves present on both faces of each of the disks are spiral-shaped, curving clockwise and counterclockwise, being arranged crossways to the grooves of the side facing the adjacent disk, both counterclockwise and clockwise; and in that between the crossed grooves of two side-by-side faces of two adjacent discs, a plurality of chambers or cells distributed in concentric annular spaces, operationally suitable for the fluid veins circulating through each groove collide with the concurrent fluid vein of the conjugated groove are formed, thereby producing a loss of kinetic energy of both fluid veins by creating turbulence and heat dissipation in said chamber or cell. |
