MULTICHANNEL ROTARY VALVE FOR FLUIDS DIRECTING Russian patent published in 2009 - IPC F16K11/74 B01D15/02 

FIELD: mechanical engineering.

SUBSTANCE: group of inventions refers to fitting engineering and is intended for use in devices for fluid multicomponent mixtures separation. Multichannel rotary valve for directing flows of fluids contains the first fixed head, the second rotary head and actuator for rotary head turning. The first fixed head has at least one main hole for connection with fluid flow and at least one auxiliary hole for connection with chamber. Chamber contains substance. This substance contacts with fluids and solid particles. In the first fixed head at least one first bypassing channel and at least one concentric second channel is made. The mentioned first bypassing channel communicates with the main hole. Actuator for turning rotary head has at least one radial chamber. Radial chamber has mutually spaced first and second holes for connection with the first or the second bypassing channel and auxiliary hole. The rotary head forms hydraulic seal with fixed head. Actuator for turning rotary head is positioned with possibility of interconnection of selected main holes with selected auxiliary holes with the help of radial chambers. There is version for implementation of multichannel rotary valve.

EFFECT: improvement of valve operation reliability.
