FIELD: machine building.
SUBSTANCE: invention refers to adjusting pipeline accessories and is designed for disk valves of medium and big diametres used in process lines of HS (heat stations), AS (atomic stations) and petrochemical production. The valve consists of fixed saddle (4) installed in case (1); the saddle has through profiled openings contacting with slide (5) made with notches; in cylinder (8) of the slide there is installed piston (9) with unloading chamber (12). Reinforcing rib (6) and support (7) are installed in case (1). Cover (13) of slide (5) contacts holding down device (14). Spindle (25) passes through cover (27) of case (1). The valve is equipped with a lever mechanism in form of lever (24) interacting with a universal hinge by means of pin (23); the universal hinge is made in form of three links (22, 20 and 16) and rod (18) connected between them with pins (21, 19 and 17 correspondingly) and secured on slide (5) with finger (15). Horizontal installation of spindle (25) is possible.
EFFECT: increased reliability of operation life of valve due to lever mechanism.
