EXPLOSIVE VALVE Russian patent published in 2006 - IPC F16K17/14 

FIELD: mechanical engineering.

SUBSTANCE: explosive valve comprises housing provided with one inlet and at least one outlet ports. The housing has the space with the cylindrical bore that receives the piston and cut diaphragm made in block with the piston. The cut diaphragm is made by cutting grooves on the cylindrical surfaces and face of the piston. The explosive valve also has the explosive chamber and conical plug mounted for permitting wedging in the answered conical seat made in the space of the housing and disconnecting the outlet and inlet ports. The cross-piece that separates the space into two isolated spaces is interposed between the inlet and outlet ports. The outlet port enters the cylindrical bore that receives the piston. The piston is provided with the rod provided with striker from the side of the cross-piece. The diameter of the striker exceeds that of the rod. The conical plug is interposed between the rod and piston and is rigidly connected with the rod.

EFFECT: enhanced reliability and expanded functional capabilities.
