LIQUID MEDIUM FLOW MULTIWAY SWITCH Russian patent published in 2017 - IPC F16K11/74 

FIELD: machine engineering.

SUBSTANCE: liquid medium flow multiway switch contains a body with equally-spaced with angular pitch α T-shaped radial distribution ducts, the upper and lower end covers, between which and the body end faces are respectively positioned the upper disk damper with one hole and a lower disc damper with amount of holes one less than the number of T-shaped radial distribution ducts in the housing, arranged with an angular pitch equivalent to the arrangement of radial distribution ducts so, that they all are blocked by the upper disc damper, and the dampers are connected by the shaft disposed along the axis of the housing and form with the upper and lower end covers, respectively upper and lower cavity, at that the upper cavity has the ring shape, formed by the ring inner surface of the upper end cover, and communicates with the liquid supply duct to the metering unit, and the lower cavity communicates with the liquid supply duct into the pipeline, at that the upper and lower disc dampers are oriented with the ability to switch the liquid supply duct to the metering unit through the opening in the upper disc damper to the T-shaped radial distribution ducts, and on the surfaces of the upper and lower end covers and the housing, contacting the disc dampers, the plain circular bearing are arranged, wherein the flat surfaces of the upper and lower surfaces of disc dampers are sealed along the housing by means of spring-loaded seats, installed in the vertical sections of the T-shaped radial distribution ducts and provided with ring inserts at the sealing surfaces.

EFFECT: invention simplifies the process of liquid medium flow distribution, with simultaneous sealing of the space between the isolated device cavities and improves its reliability.
