GATE VALVE OF STOP VALVE Russian patent published in 2019 - IPC F16K47/04 

FIELD: machine building.

SUBSTANCE: invention relates to valve industry, and can be used in process pipelines of various industries, mainly at high pressures of medium. Shutoff valve of shut-off pipeline valves comprises a shut-off element controlled through a flexible element by means of a spindle, dividing the housing passage channel into cavities of inlet and outlet branch pipes, and spindle nose interacts with valve shutting off bypass channel in shutoff member, wherein the valve is fixed on the spindle tip in a movable manner and interacts when the gate closes with the end face of the vertical part of the bypass channel, and between spindle collar shoulder and shoulders of upper surface of t-shaped slot of shutoff member there is a gap equal to height of valve lift.
