CS245748B1 - Damper with a through hole in a gate valve - Google Patents

Abstract

The solution belongs to a shut-off pipe fitting and is intended to be used primarily for the transport of solid materials. · The target is to increase reliability. The force cylinder plungers within the housing are limitedly movably connected to the ends of the flat slider, whose cross-sectional area is as large as the cross-sectional area of each plunger. Guide channels are provided on the end faces of the slider and plunger at the points of connection to prevent solid particles from remaining inside the slider housing as the slider and plungers move, thereby providing increased slide reliability.
