Title:

HIGH DIFFERENTIAL PRESSURE REGULATING VALVE

Document Type and Number:

WIPO Patent Application WO/2000/061975

Kind Code:

A1

Abstract:

A high differential pressure regulating valve which regulates a fluid amount by sliding a valve disc in a cage body having a plurality of communication holes so as to open and close the communication holes, wherein the plurality of communication holes (10) independent of each other are provided in the cage body (5) installed in a valve disc mounting chamber disposed between a fluid inlet and a fluid outlet so that the communication holes have a path bent within a cylindrical surface concentric with the axis of the cage body, and a plurality of cylindrical bodies having a bent groove formed in its surface are connected to each other so as to form the cage body (5), whereby many bends are provided to the fluid path so as to effectively absorb the energy of a high pressure fluid in order to reduce a noise and cavitation.
