FIELD: oil and chemical engineering.

SUBSTANCE: technical solution relates to the field of oil and chemical engineering and can be used as a locking device on pipelines. The gate valve comprises a housing made of two half-bodies, between which a spacer ring is rigidly fixed, in the inner cavity of which a disk gate is placed with the possibility of rotation in its plane. The semi-housings are equipped with movable seats interacting with the disk gate with springs protected from the ingress of the working medium by rubber sealing rings. The disk gate has a boss with a through hole, into which an axle is inserted, which attaches the rod to the disk gate. On the other hand, the rod is connected to the drive crankshaft.
