POWDER GAS REMOVAL SYSTEM (OPTIONS) Russian patent published in 2021 - IPC F41H7/03 

FIELD: military equipment; powder gas removal systems.

SUBSTANCE: invention relates to the field of military technology, in particular to powder gas removal systems, designed to reduce the gas contamination of inhabited and uninhabited combat compartments and modules with powder gases, the source of which is the weapons used. The powder gas removal system contains an exhaust arm, the inlet of which is connected to the source of the powder gases, and the outlet is connected to the inlet of the exhaust fan, the outlet of which is connected to the inlet of the exhaust valve mechanism, the outlet of which is brought out of the combat module into the external environment, which contains an electromagnet with limit switch. According to the invention, a digital control unit is additionally introduced, electrically connected to the fire control system of the application object, the exhaust fan and the exhaust valve mechanism through an electromagnet with a limit switch. The electromagnet is designed to provide remote opening and closing of the exhaust valve mechanism, while the exhaust valve mechanism is additionally equipped with a manual control mechanism. The difference of the second option of the powder gas removal system is that the supply arm and the supply valve mechanism, with an electromagnet included in it, providing remote opening and closing of the supply valve mechanism, equipped with a limit switch, and a manual control mechanism, are additionally introduced. The electromagnet of the exhaust valve mechanism is designed to provide remote opening and closing of the exhaust valve mechanism. In addition, the exhaust valve mechanism is additionally equipped with a manual control mechanism, and the outlet of the supply arm is connected to the source of powder gases, and the inlet is connected to the outlet of the supply valve mechanism, the inlet of which is brought out of the combat module to the compartment of the application object with purified or unpolluted air. Wherein, the digital control unit is electrically connected to the fire control system of the application object, the exhaust fan and the mechanisms of the exhaust and supply valves through electromagnets with limit switches.
EFFECT: providing the possibility of remote electromechanical control of the powder gas removal system while maintaining the possibility of direct manual electromechanical control; ensuring the possibility of using a powder gas removal system in uninhabited and remotely controlled combat compartments and modules; automation of control of switching on and off the ventilation system; increasing the efficiency of removal of powder gases; introducing the function of adjusting (changing) the fan performance to ensure the coordinated operation of the powder gas removal system together with the air purification system (for example, a filter ventilation unit) installed in the application object, with obtaining purified air from it, if it is impossible to obtain unpolluted air from the external environment; reducing the effect of the powder gas removal system on the quality of the on-board network of the application object in conditions of limitations in the combat module for the maximum power consumption of the on-board network; expanding the possibilities of using the powder gas removal system in various objects of military equipment without being tied to a specific fire control system; increasing the ease of operation and maintenance of the powder gas removal system; increasing the security of the crew located in the inhabited compartment of the application object with unpolluted or purified air used for the operation of the powder gas removal system when it is installed in the combat module, made in the form of a compartment separated from the inhabited one; reduction of the time of readiness of the powder gas removal system for operation.
