Изобретение относитс к области противопожарной техники, в частности . к жидкостным огнетупгител м с разделительным элементом между жидкостной и газовой полост ми.The invention relates to the field of fire fighting equipment, in particular. to liquid fire extinguishers with a separating element between the liquid and gas cavities.

Известен жидкостной огнетушитетш, содёржапшй баллон с газовой полостью и с размещенным в нем снпьфоном с днвоцем дл огнетушащей жидкосгга и установленную на баллоне раейыливающую головку . ,QA liquid fire extinguisher is known, containing a gas cylinder and with a double-sided snoophone for a fire extinguishing liquid and a discharge head mounted on the cylinder. Q

Недостаггком известного огнетушител вл етс -невысока огнетушаща эффектиансхугь , вызванна как непошгым вытеснением /огнетушащего вещества, так и от-, сутствиём воаможностн использовани газа 5 вытеснител дл тушени , поскольку последний вытекает не через форсунку, а через дншце огнетушкгел .Nedostaggkom known fire extinguisher is the extinguishing -nevysoka effektianskhug induced by both displacement neposhgym / fire extinguishing agent and The relative, sutstviom voamozhnostn using 5 propellent gas for extinguishing, since the latter does not flow through the nozzle, and through dnshtse ognetushkgel.

Целью изобретени вл етс повьппение производительности работы огнетушител .The aim of the invention is to improve the performance of the fire extinguisher.

Указанна пепь достигаетс тем, что в жидкостном огнетушителе, содержащем баллон с газовой полостью с размещенным в нем сильфоном с днищем дл огнетушащей жидкости И установленную на баллоне 5распыливающую головку с aanojHным устройством, (на отерытом торце, сильфона установлена крышка с обратным клапаном, имеющим шток дл контактировани с днищем, причем газова полость огнетушител сообщена с полостью над крышкой сильфона.This pepah is achieved by the fact that a liquid fire extinguisher containing a gas cylinder with a bellows placed in it with a bottom for fire extinguishing fluid AND a spraying head mounted on the cylinder 5 with a device, with a stem contact with the bottom, with the gas cavity of the fire extinguisher in communication with the cavity above the bellows cover.

На фиг. 1 изображен предлагаемый огн€ тушитель с частичньтм вырезом стен ки баллона, общий вид; на фиг. 2 - узел фйг. 1.FIG. 1 shows the proposed fire extinguisher with a partial cut-out of the cylinder wall, general view; in fig. 2 - fig node. one.

Claims

The fire extinguisher consists of the spray head 1, the trigger guard 2, the 3 N pipeline of the valve 4. The valve stem is spring-loaded and ends with a knife located above the membrane 5. The valve 4 is installed on the cylinder 6, in which the bellows 7 with the extinguishing agent is located. On the open torp of the bellows, a cover 8 is installed, made in the form of a kopacka. On the lid there is a non-return valve for the discharge of gas with spring-loaded stem 9 in housing Yu. The free end of rod 9 is long inside the pipe 7 and has a collar t for gas passage. The free end of the rod 9 has a smaller DESS meter than the hole in the housing Y. The lid 8 in the symphonts 7 is tucked into the lid of the 11th boom 6 by the nut 12, which has the holes Mezvdu Krishka 8 11, and also the grooves on the end of the hull of the BV pon 6 which, together with the holes in the nut 12, form the channels connecting the cavity of the crankshaft 8 of the pypone 7 with the gas cavity of the balloon 6. The fire exchanger is filled with compressed gas through the rod 13. The fire extinguisher works as follows. The operator presses the trigger guard 2, kotfa impacting the stem "valve 4, and the latter moves, compressing the spring, and cuts off the membrane 5 with his knife i. The fire extinguishing device under the pressure of the compressed gas is displaced from the pyfon 7 through pipe 3 and the spray nozzle 1 on fire center, bellows 7 is compressed at the end of the compression section from the goof 7 Fire extinguishing air is completely out of place, since the height of the roof 8 corresponds to the height of the compressed bellows 7. At the same time the bottom of the bellows 7 presses onto the collar of the rod 9, feather burghers it. The compressed gas from the gas strip of the cylinder 6 through the corresponding channels and from the cavity of the bellows 8 of the bellows through the gap between the rod 9 and the body Yu enters the Pipeline 3 and completely displaces it from there. A fire extinguishing agent through the spray head 1 on the center of fire. After that, the compressed gas from the fire extinguisher is supplied to the fire center, continuing the extinguishing process. The fact that the proposed design contains a flap with a device for relieving pressure through a non-return valve into the liquid cavity of the fire extinguisher allows for the complete expelling of the fire extinguisher and the subsequent supply of compressed gas to the fire center, which increases the fire extinguishing efficiency of the fire extinguisher. Claims of the Invention A liquid fire extinguisher containing a gas cylinder with a bellows placed in it with a bottom for the fire extinguishing liquid and a spray head mounted on the cylinder with a locking device, so that, in order to increase its efficiency, it has at the open end of the bellows a bolt valve with a check valve having a stem for contacting the bottom of the bellows, with the gas cavity of the fire extinguisher in communication with the cavity above the bellows of the bellows. .
