20150129786 | FLUID CONTROL VALVE FOR HIGH PRESSURE SURGES - 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. | 05-14-2015 |
