(54) УСТРОЙСТВО ПОЖАРОТУШЕНИЯ(54) FIRE EXTINGUISHING DEVICE

1one

Изобретение относитс к пожарной технике , а именно к устройствам подачи огнегасительной жидкости дл тушени пожара.The invention relates to fire fighting equipment, in particular, to fire extinguishing liquid supply devices for extinguishing a fire.

Известно устройство пожаротушени , содержашее размеш:енный в цилиндрическом корпусе с крышкой поршень с полым штоком , образуюшие с крышкой корпуса форкамеру , мембраны, закрывающие выходные отверсти в днище корпуса и торце штока, и силовозбудитель.A fire extinguishing device is known that contains: a piston with a hollow rod in a cylindrical housing with a cover, forming a prechamber with a housing cover, membranes covering the outlet openings in the bottom of the housing and the end of the rod, and the energizer.

Во многих случа х дл эффективного тушени пожара целесообразно одновременно подавать на очаг пожара как распыленную жидкость, так и жидкость в виде струй и крупных капель в течение определенного времени , позвол ющего полностью потушить очаг пожара 1.In many cases, in order to effectively extinguish a fire, it is advisable to simultaneously apply to the fire center both sprayed liquid and liquid in the form of jets and large drops for a certain time, allowing to completely extinguish the fire site 1.

Недостатком данного устройства вл етс кратковременность его работы, так как врем гор шей поверхности лимитируетс объемом камер с огнетушащей жидкостью. Если врем , необходимое дл тушени больше времени работы устройства, то пожар не будет потушен.The disadvantage of this device is the short duration of its operation, since the time of the high surface is limited by the volume of the chambers with extinguishing liquid. If the time required to extinguish the device is longer, the fire will not be extinguished.

Целью изобретени вл етс повышение эффективности пожаротушени .The aim of the invention is to increase the efficiency of fire extinguishing.

Указанна цель достигаетс тем, что устройство пожаротушени , содержашее размешенный в цилиндрическом корпусе с крышкой поршень с полым штоком, образуюш,ие с крышкой корпуса форкамеру, мембраны,This goal is achieved by the fact that a fire extinguishing device, containing a piston with a hollow rod in a cylindrical housing with a lid, forming a prechamber chamber, membrane, with a lid,

5 закрывающие выходные отверсти в днище корпуса и торце штока, и силовозбудитель, оно имеет установленный на крыщке корпуса вентиль, а днище порщн имеет отверсти и установленные в них подпружиненные паны, при этом днище корпуса имеет выступы дл контактировани с клапанами, а силовозбудитель выполнен в виде водопитател , сообщенного через вентиль с форкамерой .5 closing the outlet openings in the bottom of the housing and the end of the stem, and the energizer, it has a valve mounted on the housing cover, and the bottom of the piston has holes and spring-loaded pans installed in them, the bottom of the housing has projections for contacting the valves, and the exciter is made in the form water drain through valve with prechamber.

На чертеже изображено устройство, об15 щий вид в разрезе.The drawing shows a device having a general sectional view.

Устройство имеет цилиндрический корпус 1, верхнюю крышку 2, дистанционно-управл емый вентиль 3, поршень 4, имеющий подпружиненные клапаны 5, полый штокThe device has a cylindrical body 1, a top cover 2, a remotely controlled valve 3, a piston 4 having spring-loaded valves 5, a hollow rod

Claims

2-, 6 forming the pre-chamber 7 for the fire extinguishing fluid and the bottom 8 with the piston and cover. The outlet opening of the rod 6 is closed by a membrane 9. An outer chamber 10 filled with fire extinguishing liquid or a flame retardant solution is formed between the walls of the housing, the bottom and the hollow stem. Sprayers 8 are mounted on the diische 8, the outlet openings of which are closed by membranes 12. In addition, the bottom 8 has an annular protrusion 13 and a guide support 14. The water supply 15 is connected to the housing lid through a valve. The device works as follows. In the standby position, chambers 7 and 10 are filled with extinguishing liquid. A remote-controlled valve 3, which can be used as valves with different actuators, for example, with a actuator, electric actuator, pneumatic hydraulic actuator, etc., is connected to an energizer, which is a water supply of any design, namely a pressure water supply system, a pneumocharger , pumping station, etc. When ignited, the signal is sent to a remote controlled valve. It is triggered and the water from the water pressurizer is fed into the device under pressure. Porschen 4 begins to move, with the membranes 9 and 12 breaking through. The fire extinguishing fluid from the prechamber 7 is fed to the fire tugging in the jet mode, and from the outer chamber 10 through the spray guns 11 in a spray form. When the bottom position 4 is reached, in which the spring-loaded valves 5 open when they hit the annular protrusion 13, the initial supply of fire-extinguishing agent in the device runs out. In this case, to extinguish the fire, water is supplied from the water gun through the hole in the rod b in the jet mode, and through the open valves 5 and through the spray guns 11 in the atomized mode. The use of such a construction makes it possible to deliver the extinguishing agent and water for the time necessary and sufficient to completely suppress the combustion. The proposed device can be used to extinguish flammable solid and bulk materials. The invention of a fire extinguishing device comprising a piston with a hollow rod placed in a cylindrical housing with a cover, forming a prechamber with a housing cover, membranes covering the outlet openings in the bottom of the housing and the end of the stem, and exciter, characterized in that, in order to increase the efficiency of fire extinguishing it has a valve mounted on the housing cover, and the piston bottom has openings and spring-loaded valves installed in them, wherein the housing bottom has lugs for contacting with the valves, and The beater is made in the form of a water flow communicated through a valve with a pre-chamber.
