GAS DISCHARGE VALVE OF CHAMBER FOR PROCESSING MATERIALS BY EXPLOSION ENERGY Russian patent published in 2019 - IPC F16K24/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to ventilation blasting chamber (BC). Gas outlet valve (GV), made in the form of a body with a seat (S), connected to the chamber (C) wall, having a movable gate (G) opening into cavity (C), where conjugated surfaces (G) and (S) are conical, characterized by that (G) is made with slots arranged on its conjugated with (S) surface, forming in contact with (S) throttling channels connecting cavity (C) with ventilation system.

EFFECT: presence of durable (G) with throttle channels provides reliable release of pressure of gaseous explosion products occurring after explosion of explosive charge in (C), with reflection of shock wave without passing it to exhaust ventilation system, generally improving operating reliability of (BC).
