FIELD: machine building.
SUBSTANCE: invention relates to piping accessories and is provided for disk valves of average and high diametres, applied in process lines of heat station, nuclear power plant and petrochemical manufacturing. Valve contains installed in casing stationary saddle with through-pas windows, mobile slide valve, connected to drive spindle by means of draw bar and lever. Slide valve is implemented in the form of separate leaf-gates, fixed on balancing arm and by shape of corresponding to through-pas windows of stationary saddle. Balancing arm is installed on central limit stop, including flat-thrust bearing, taking pressure force of leaves to saddle. Leaves are outfitted by float peripheral compression, implemented from several elements, compressed by springs to saddle and fixed by screws.
EFFECT: reliability growth and durability of valve operation.
