The system of localization of explosions of SLVA is intended for detection of flashes (explosions) of methane and coal dust in an initial stage from development and creation of the vzryvopodavlyayushchy environment preventing their distribution on development by positive feed of vzryvopodavlyayushchy substance in an ignition center zone in the coal mines dangerous on gas and dust.Is established in places of the most probable emergence of explosions and is more effective remedy of localization of explosions, than the passive slate and water barriers applied now.
The system provides:
- automatic detection of a flame in an initial stage of emergence of the fire or explosion;
- supply of plamegasyashchy substance in the protected zone;
- control of operability of functional assemblies;
- reservation of a power supply of devices of suppression of explosion.
It is applied in the mines dangerous on a gas burst and dust at air temperature ranging from-10 to +50 °C, relative humidity at a temperature of 25 °C up to 100% and dust content of air to 1000 mg/m ³.
Are included in the package of delivery of SLVA:
- flame sensor compact DPK, 2 pieces;
- device of suppression of explosion of UPV-ZOP, 2 pieces;
- distribution box KR, 2 pieces;
- block of interface to the BSP actuator, 1 piece.
