Zusammenfassung:	clack-type check valves whose shut-off members open by medium being handled at direction of flow under shut-off member of valve; shut-off non-return fittings for periodic or one-time placing in operation or disconnecting parts of pipe lines; nuclear power, petrochemical and gas industry. SUBSTANCE: proposed valve has body with inlet and outlet branch pipes, gate consisting of shut-off member and lever connected with it, stem and drive for motion of stem. Gate is additionally provided with detachable bracket secured on body and articulated with lever of gate. Stem is provided with end-piece whose guide are engageable with surfaces of body slots. End-piece is provided with projection engageable with lever. Surface of lever is profiled in area where it is engageable with projection of end-piece. EFFECT: extended operational capabilities of valve; enhanced operational reliability and maintainability due to facilitated assembly and disassembly; reduced consumption of labor required for repair. 2 dwg
