PYRO-VALVE Russian patent published in 2017 - IPC F16K17/14 

FIELD: machine engineering.

SUBSTANCE: pyro-valve, which provides for the weakened section comprises a housing with inlet and outlet fittings, the cutter and the piston with a rigidly fixed on it stock. The input, output and fittings disposed locking element formed integrally between them. Thus on the locking element that is rigidly connected to a rod arranged symmetrically about the axis of the housing weakened section. Moreover, on the rod locking element from its conical annular portions are gears, one side of which is at an angle directed along the movement of the rod. When this piston is situated coaxially the pressing member, wherein a groove for a sealing ring of PTFE, which is placed between the ring of elastic material. Clamping element interacts with the body by threads. Pyrocartridges, one of which is redundant, rigidly fixed on both sides on the body perpendicularly to its axis. Pirokamera for powder gases is a cavity formed by the squib, the pressing member and the piston side end of the body on which the vent valve is installed.

EFFECT: increased efficiency pyro valve operation.
