STRUCTURE FIRE FLOW mist fire-extinguishing liquid or flow FOAM AND SPRAY FOR THEIR FORMATION

摘要

The invention relates to fire fighting equipment, namely to the devices with a charge of extinguishing a fire-extinguishing liquid as the extinguishing agent (CSP) both from the possibility of fire extinguishing mist flow of extinguishing liquid with a given level of dispersion and a foam flow with a predetermined level ratio. The fire extinguisher comprises a sealed container with a liquid fire extinguishing agent and displacing the compressed gas and the exhaust system of the liquid extinguishing agent from a sealed container comprising a siphon tube, locking-starting device and dispenser. PTV release liquid provided with a second siphon pipe which by means of U-shaped retraction sealingly connected to the gas tube, the inlet end of which is located above the initial level of the liquid extinguishing agent in the hermetic vessel. The sprayer comprises a housing and coaxially disposed therein downstream tapering compression chamber with inlet and outlet openings and the vacuum chamber with inlet and outlet openings. Luggage compression has the shape of a truncated cone with bases formed by the inlet and outlet of the compression chamber, wherein the outlet opening of the compression chamber is in the form inlet opening of the vacuum chamber, and the inner surface of the vacuum chamber between the inlet and the outlet is formed as a surface of revolution whose diameter any of its cross-sectional diameter than the cross-section of the conditioned direct truncated cone with bases formed by the inlet and outlet of the vacuum chamber. The use of utility models created by another device for extinguishing fires and fires atomized flow of extinguishing liquid or a stream of foam simplified design, equipped with respective spray, reduced complexity of manufacturing, increased reliability, and enhanced processing capabilities by providing, if necessary, repeated interruption and resumption of PTV without sacrificing operational performance. 2N. 13 and ZP f-ly; 3 yl.
