A gate valve having a casing, a seat, a gate having a tapered face made in the gate surface in the direction of its movement in the shut-off direction on the side opposite to the side facing toward the seat, a stop provided for engaging the tapered face of the gate, the stop being secured to a rod which is installed transversely of the centerline of a passage of the casing, a sleeve installed in the casing wall for rotation relative to the casing, the inner surface of the sleeve being coaxial with, and surrounding the rod, and the longitudinal centerline of the outer surface of the sleeve being eccentric with respect to the longitudinal axis of the rod.

Gate valve

A gate valve for a pipeline has a housing with butt pipes which define a passage with the pipeline and a gate having a hole and engageable with a butt pipe for shutting-off the passage. The gate is connected at its ends to ends of drive rods accommodated in the housing. The gate and each of the rods have equal areas taken in cross-sections perpendicular to the axis of the rods. The ends of the gate and the ends of the rods connected thereto have shaped end faces facing toward each other and designed for the passage inside the housing of solid particles of a fluid being conveyed during reciprocations of the gate from a space partially occupied by the gate to a space being left by the rod adjacent thereto, and also from a space occupied by the other of the rods to a space being left by the part of the gate adjacent thereto.
