REPLACEABLE VALVE DEVICE FOR USE IN FLUID FLOW RATE REGULATORS Russian patent published in 2016 - IPC G05D16/06 

FIELD: valves.

SUBSTANCE: proposed interchangeable valve device for use with fluid flow rate regulators. Option of suggested valve device includes first holding device, connected with possibility of disconnection with passage for fluid flow control of fluid medium between inlet and outlet holes. First holding device contains first housing containing first channel to accommodate flow control unit, first retainer appliance has first hole coaxially aligned with first channel to form first orifice passage for fluid medium flow, when holding device is connected with fluid flow regulator. Fluid medium flow regulator additionally comprises second holding device, differing from first holding device and interchangeable with it, besides, second holding device contains second body having second channel to accommodate flow control unit. Second holding device comprises second orifice, coaxially aligned with second channel to form second orifice passage for fluid medium flow, when second holding device is connected with fluid flow regulator. First holding device provides first characteristic of fluid medium flow, and second holding device provides second fluid flow characteristic, different from first fluid medium flow characteristics. Change in characteristics of fluid flow is due to availability of first and second holding devices having orifices with different diameters or sizes.

EFFECT: technical result is reduction of total number of components to provide wide range of characteristics of fluid in fluid flow rate regulator.
