REUSABLE START VALVE WITH EXTENDED IMPACT ZONE Russian patent published in 2019 - IPC A62C37/08 A62C37/20 

FIELD: valves.

SUBSTANCE: reusable start valve with an extended impact zone (hereinafter referred to as EIZ valve) comprises a housing connected by an inlet channel with a capacity of a fluid extinguishing agent under pressure, on its side surface an outlet window is located, hermetically sealed by a locking piston with a seal, locking piston is located in the inlet channel of the housing, the inlet channel of the housing is cylindrical with the possibility of movement in it of the locking piston, seal of the locking piston is located on its lateral cylindrical surface; the source of the control pressure is an exploder equipped with a reinforcing powder sample. Locking piston has a hermetic partition, which is destructible when the valve is actuated, inside the locking piston there is a pushing piston with a seal, outlet window is located in a swivel unit containing a stationary part with an outlet channel and seals, fastened to the valve body and a rotating part located inside the stationary part with seals, an outlet window and an actuator (for example, a reversible electric motor), the exploder is equipped with the reinforcing powder sample. Proposed technical solution can be used as a start valve in various fire-fighting systems, as well as in emergency pneumo-hydraulic systems.

EFFECT: invention solves the problem of simplifying the design and manufacturing technology, reducing the number of parts and thereby improving reliability, reducing mass and dimensions, and expanding the impact zone of a fire extinguishing substance on sources of ignition.
