PIPELINE VALVE BODY Russian patent published in 2013 - IPC F16K27/10 

FIELD: construction.

SUBSTANCE: pipeline valve body, comprising a shell, connected with an elliptical bottom, having a support, two coaxial nozzles with seats fixed in the body by ribs that covers a gate at two sides, which is controlled by a spindle arranged coaxially in a stand fixed on a cover connected to the body by means of flanges, in the inner cavity of the body symmetrically along the vertical plane perpendicular to the axis of nozzles there are the following items installed as interacting with response surfaces of the gate in pairs: inclined stops on the bottom, stops with inner slants towards the body flange in the middle of the gate length, in the upper part of the gate length - detachable stops. Detachable stops with one end interact with slants of middle stops, and with the other end are fixed on ribs that fasten the nozzles.

EFFECT: development of a pipeline valve body design permitting and providing for gate position in the body and eliminating spindle deformation, when an assembled valve is transported in horizontal position.
