The invention relates to a multi-cylinder segmentation structure of a propellant of an aerosol fire extinguishing device, which has the following beneficial effects:
1. the invention provides a safe, effective and strong-practicability multi-cylinder segmentation structure of aerosol fire extinguishing device propellant, which has compact and simple structure, high reliability and convenient installation.
2. According to the multi-cylinder partition structure, the isolating screen cover, the propellant grains and the propellant cylinder are effectively combined, the propellant grains coated by the silica gel are placed into the propellant cylinder and are fixed by the isolating screen cover, so that the dosage of a single propellant grain is greatly reduced, the propellant grains can be protected and effectively insulated by the silica gel coating, the risk of deflagration of the whole propellant is reduced, and the safety of the aerosol fire extinguishing device is greatly improved.
Drawings
FIG. 1 is a first schematic structural diagram of the present invention;
fig. 2 is a second structural schematic diagram of the present invention.
In the figure: 1-an isolation sieve cover, 2-a propellant grain, 3-a propellant cylinder and 4-a discharge port.
Detailed Description
As shown in figures 1 and 2, the multi-cylinder partition structure for the propellant of the aerosol fire extinguishing device comprises an isolation screen cover 1, propellant grains 2 and a propellant cylinder 3, wherein a discharge opening 4 for normal discharge is formed in the isolation screen cover 1, the propellant grains 2 are located in the propellant cylinder 3, and the number of the propellant grains 2 is two or more.
The propellant grain 2 is coated by silica gel. The section of the propellant grain 2 is circular, oval or other geometric shapes which can be formed.
The generating agent cylinder 3 is of a single-end closed thin-wall structure, and the cross section of the opening end is circular, oval or other geometric shapes which can be formed.
The discharge opening 4 is of a single-hole or porous structure, and the shape of the opening is circular, oval or any other geometric shape capable of being formed.
The isolation screen cover 1 and the propellant cylinder 3 are fixedly connected by clamping, riveting, welding, thread connection, pin connection or other modes.
Or: the isolation screen cover 1 and the propellant cylinder 3 are directly connected into an integrated connection.
When this multi-cylinder segmentation structure is used at the aerosol extinguishing device, discharge port 4 uses as the discharge port of aerosol extinguishing device propellant cylinder 3, and isolation sieve lid 1 and propellant cylinder 3 take place rigid connection, and the two connect to become an organic whole. The propellant grain 2 coated by silica gel is placed in the propellant cylinder 3, when the fire extinguishing device is started, all the propellant grains 2 coated by silica gel in the propellant cylinder 3 are ignited at the same time, so that the quantity of aerosol generated in unit time is the same as that of aerosol generated by a single propellant grain of the same mass; the difference is that each propellant grain 2 of a multi-cylinder partition structure reacts independently, the generated heat is reduced by times, and because of the protection of the coated silica gel: on the one hand, the heat generated by each propellant grain 2 can be isolated, and on the other hand, even if one propellant grain 2 generates deflagration, the normal reaction of other propellant grains 2 can not be influenced, so that the risk of deflagration generated by the whole propellant is obviously reduced, and the safety of the aerosol fire extinguishing device is greatly improved.
The specific structural form of the multi-cylinder segmentation structure of the aerosol fire extinguishing device propellant can be seen in fig. 1 and 2.
