Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1 to 3, a fire extinguishing device with a paper sticking and pressure releasing structure comprises an outer cylinder 1 and a fire extinguishing agent grain 2 arranged in the outer cylinder 1, wherein one end of the fire extinguishing agent grain 2 is connected with the tail end of a starting component 3, a front cover 4 is arranged on the front side of the outer cylinder 1, a nozzle 5 and a pressure releasing opening 6 are formed in the surface of the front cover 4, the pressure releasing opening 6 is located in the central area of the front cover 4, the nozzle 5 is located in the peripheral area of the front cover 4, a nozzle diaphragm 7 is attached to the nozzle 5, a pressure releasing diaphragm 8 is attached to the pressure releasing opening 6, and the thickness of the pressure releasing diaphragm 8 is larger than that of the nozzle diaphragm 7. In this embodiment, since the thickness of the pressure release membrane 8 is greater than the thickness of the spout membrane 7, the spout membrane 7 is more easily compressed and torn relative to the pressure release membrane 8, so in the actual manufacturing process, the pressure release membrane 8 and the spout membrane 7 with corresponding thicknesses can be selected according to the pressure parameter of the fire extinguishing device when the fire extinguishing device is normally sprayed and the pressure parameter of the fire extinguishing medium when the fire extinguishing medium is abnormally sprayed or the channel is blocked, respectively, so that the spout membrane 7 can be torn and opened when the fire extinguishing device is normally sprayed, and the pressure release membrane 8 can be torn and opened to perform the pressure release process when the pressure is suddenly increased due to the abnormal spraying or the channel blockage of the fire extinguishing medium.
Preferably, the front cover 4 is bonded or welded to the spout membrane 7 and the pressure relief membrane 8.
Preferably, the pressure relief openings 6 are distributed on the surface of the front cover 4 in an annular array.
Preferably, the spout membrane 7 covers the outside or inside of the spout 5, and the pressure release membrane 8 covers the outside or inside of the spout 5.
Preferably, the spout membrane 7 and the pressure release membrane 8 are pvc decals or frangible decals or plastic films or rubber films. The materials can be torn and opened normally under pressure, and can also prevent water vapor from entering the fire extinguishing device during storage, so that the phenomenon of moisture absorption of the fire extinguishing agent grain 2 or the coolant 9 is avoided.
Preferably, a coolant 9 is also provided between the extinguishing agent column 2 and the nozzle 5. The high-temperature fire extinguishing substance generated by the fire extinguishing agent grain 2 can be cooled by the cooling agent 9, so that the temperature at the nozzle 5 is not too high.
Preferably, the fire extinguishing agent column 2 is a column structure made of aerosol generating agent.
Preferably, a silica gel coating layer 10 is further arranged between the surfaces of the fire extinguishing agent grain 2 and the coolant 9 and the inner side of the outer cylinder 1. The silica gel coating layer 10 can play a role in heat insulation, when the fire extinguishing agent grain 2 is ignited, high temperature is generated, and in order to prevent the outer cylinder 1 from heating and scalding, the problem can be effectively solved by arranging the silica gel coating layer 10.
Preferably, the front side of the outer cylinder 1 is in threaded fit with the front cover 4, the rear side of the outer cylinder 1 is provided with a rear cover 11 in threaded fit with the front cover, and the rear cover 11 is provided with a through hole for penetrating the starting component 3.
Preferably, the starting part 3 is an electric ignition head or a heat-sensitive wire structure. In the present embodiment, when the starting member 3 is of an electric ignition head structure, it is connected to a fire detection device (the fire detection device is a temperature sensor and/or a smoke sensor). When fire, overheat and other conditions occur, the fire detection device detects the high-temperature environment generated by the fire, and then sends a signal to the microprocessor, and the microprocessor controls the starting component 3 to ignite the fire extinguishing agent grain 2. When the starting component 3 is of a thermosensitive line structure, the thermosensitive line structure is simpler, so that the fire extinguishing agent column 2 can be automatically started when a fire disaster occurs when the thermosensitive line is adopted, and the thermosensitive line can directly ignite the fire extinguishing agent column 2 without being matched with an additional fire disaster detection device and other external equipment.
The working principle of the embodiment is as follows:
when the whole fire extinguishing device is not in a fire extinguishing state, the nozzle diaphragm 7 and the pressure release diaphragm 8 can effectively form a seal in the outer cylinder 1, so that the phenomena of decomposition, aging, moisture absorption and the like of the fire extinguishing agent grain 2 in the fire extinguishing device are prevented from being caused after moisture in the outside air enters the fire extinguishing device; when a fire occurs outside, the starting part 3 ignites the fire extinguishing agent grain 2, the fire extinguishing agent grain 2 in the embodiment is a grain pressed by aerosol generating agent, and the fire extinguishing agent grain 2 burns to generate fire extinguishing substances such as aerosol or gas; in the normal fire extinguishing process, the nozzle diaphragm 7 can be pressed to be torn and opened, and at the moment, fire extinguishing substances are sprayed out from the exposed nozzle 5 to perform the fire extinguishing process; in the normal spraying process, the pressure of the pressure release opening 6 to the pressure release diaphragm 8 is insufficient to damage or drop the pressure release diaphragm 8 because the thickness of the pressure release diaphragm 8 is larger than that of the nozzle diaphragm 7; when the pressure suddenly increases due to abnormal spraying of the fire extinguishing medium or blockage of a channel, the pressure release diaphragm 8 can be torn and opened by being pressed, so that the pressure release opening 6 is exposed for pressure release.
The above embodiments are merely preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the embodiments and features of the embodiments of the present utility model may be arbitrarily combined with each other without collision. The protection scope of the present utility model is defined by the claims, and the protection scope includes equivalent alternatives to the technical features of the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
