STOCK ASSEMBLY FOR ROTATING VALVE AND METHOD OF ITS ASSEMBLAGE Russian patent published in 2015 - IPC F16K5/06 F16K27/06 F16K5/08 

FIELD: machine building.

SUBSTANCE: group of inventions relates to valve industry and is intended to be used as shutoff valve in pipelines. The rotating valve contains a body, limiting port for valve stock, and through channel passing through the said valve. The valve stock contains increased part with size exceeding port for the valve stock, thus ensuring the stock securing in the valve body by limiting the radial external movement of the said stock relatively to the valve body. The rotating element contains the top and bottom shoulders. To provide the support with possibility of rotation for the top and bottom shoulders the top and bottom split holders with split elements are used, the elements can be inserted at opposite sides of the valve body ensuring the rotating element rotation with simultaneous prevention of the axial movement along the axis of the through channel. There are options of the rotating valve manufacturing, and options of their assemblage.

EFFECT: group of inventions is aimed at improvement of the valve operation reliability.
