FULL-PASSAGE GATE VALVE Russian patent published in 2019 - IPC F16K3/06 F16K27/04 

FIELD: machine building.

SUBSTANCE: invention relates to oil and chemical machine building and can be used as a locking and control device on pipelines transporting aggressive working medium, for example, oil with high volumetric content of CO₂ and H₂C, process water under pressure of up to 35 MPa, as well as for shutting off channels of wellhead valves of fountains, pump and injection wells. Full-passage gate valve is formed of two half-bodies made without flange, with through holes with seats, between the half-bodies there is a cavity, in which, with possibility of rotation in its plane, a gate with a gear rim interacting with the drive shaft, in the half-bodies there are through coaxial holes, on the external surfaces of the half-bodies there are blind threaded holes, through coaxial holes and blind threaded holes are made at the same distance from the axis of the through hole.

EFFECT: invention is aimed at creation of a universal full-passage gate valve characterized by low metal consumption, small dimensions and ease of manufacture.
