FLUID SWITCHING DEVICE Russian patent published in 2015 - IPC F16K11/20 B01D35/12 

FIELD: machine building.

SUBSTANCE: invention relates to pipeline valves and is intended for use as switching device for fluid under high pressure, that is delivered, selectively, via the first or second device for treatment, for example, filtering with chemical and/or physical treatment. The switching device contains a first fluid passage connection (5) and second fluid passage connection (6), they are located between the first and the second treatment devices (3, 4). In the first connection (5) at least one first distribution valve (7) and one third distribution valve are installed (13). In the second connection (6) the second distribution valve (8) and fourth distribution valve (14) are installed. The first pair of switching levers (11, 12) relating to the first and second distribution valves (7, 8), and the second pair of the switching levers (15, 16), relating to the third and fourth distribution valves (13, 14) are located in different planes such, that the switching levers (11, 12) of the first pair are made with possibility of activation by the user without obstacles from the switching levers (15, 16) of the said pair, and vice versa.

EFFECT: invention simplifies manufacturing and installation of the switching device ensuring operation reliability.
