METHOD OF BODIES INTERACTION MECHANISM IN PLANE OF GATE VALVE UNIT OF WEDGE GATE VALVE Russian patent published in 2020 - IPC F16K3/12 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in oil and gas production, petrochemical, power engineering and other industries. In the method of the bodies interaction mechanism on the wedge-like gate valve unit plane, the self-braking mechanism inclined surface is installed with the self-braking safety factor and is determined by the relative movement from the condition ψ_rel=2f/f+tgα, where f is Amonton friction coefficient; α – angle of action of input force – angle of rise in radians, between line connecting wedge, which at this moment of time moves in direction of inner plane of housing, on which brakes presses to hold load on reverse stroke.

EFFECT: increasing operating efficiency of wedge gate valve for self-braking at retention of load at reverse stroke.
