Fig. 2 is a schematic structural view of a siphon of an improved perfluorohexanone cabinet-type fire extinguishing apparatus according to an embodiment of the present invention.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an improved cabinet type fire extinguishing apparatus for perfluorohexanone comprises a steel bottle hoop 1, a cabinet body 2, a fire extinguishing agent storage agent bottle 3, a signal feedback device 4, a container valve 5, an electromagnetic driving device 6, a pipeline system 7 and a nozzle 8, wherein the fire extinguishing agent storage agent bottle 3 is fixed in the cabinet body 2 through the steel bottle hoop 1, the container valve 5 is arranged at the bottle mouth of the fire extinguishing agent storage agent bottle 3, the signal feedback device 4 and the electromagnetic driving device 6 are arranged on the container valve 5, the container valve 5 is connected with the signal feedback device 4, the container valve 5 is electrically connected with the electromagnetic driving device 6, and the output end of the container valve 5 is connected with the nozzle 8 through the pipeline system 7. The electromagnetic driving device 6 needs to be externally connected with a 24V direct current power supply provided by a controller, and the driving device can be electrified to work only when the system needs to work (fire extinguishing agent is sprayed).
In this embodiment, the fire-extinguishing agent storage bottle 3 is filled with a perfluorohexanone fire-extinguishing agent and nitrogen gas under pressure. The container valve 5 is provided with a siphon 51, and one end of the siphon close to the container valve 5 is provided with a gas distribution small hole 511, as shown in fig. 2, so as to realize better fire extinguishing agent spraying atomization effect similar to the two-phase flow principle. The spray head 8 is provided with a rotary core structure for improving the atomization effect of the fire extinguishing agent. The container valve 5 is provided with a safety relief device with a buffering function, the safety relief device is arranged at a nozzle of the container valve, a damping hole structure is arranged between a channel and a main channel of the valve body, and the situation that the safety diaphragm is damaged in the moment of spraying the perfluorohexanone fire extinguishing agent can be avoided.
The signal feedback device 4 is a pressure sensor, and when the container valve 5 discharges the fire extinguishing agent, the pressure sensor can transmit a pressure signal to the controller to report that the fire extinguishing agent is sprayed by the device.
The electromagnetic driving device 6, the signal feedback device 4 and the container valve 5 are connected together through threads, when the fire control system transmits a starting signal to the electromagnetic driving device 6, a thimble of the electromagnetic driving device 6 opens the container valve 5, so that the fire extinguishing agent is sprayed under the driving of high-pressure nitrogen. At the instant of fire suppressant release, the signal feedback device 4 transmits a digital signal of the pressure to the fire controller, reporting that the device has sprayed the fire suppressant. The distribution small hole designed on the siphon has the effect that if the system leaks and leaks, a small amount of nitrogen can be preferentially discharged from the small hole at the root part of the siphon because the density of the fire extinguishing agent is high and the density of the nitrogen is low until the pressure is reduced to the normal pressure, only nitrogen is lost in the whole process, and the fire extinguishing agent is hardly lost. The container valve 5 is a differential pressure type valve body, and is opened when the electromagnetic driving device 6 is operated, so that the fire extinguishing agent is released.
In conclusion, the utility model designs the air distribution hole at one end of the siphon close to the container valve, and adds the rotary core structure on the spray head 8 to improve the atomization effect of the fire extinguishing agent. When the fire extinguishing agent is sprayed, the pressurized nitrogen in the fire extinguishing agent bottle set can be mixed with the fire extinguishing agent through the small holes at the root part of the siphon tube, flows through the pipeline system in a gas-liquid two-phase state and is finally sprayed out from the spray head with the rotary core structure, so that the atomization effect is greatly enhanced, and the fire extinguishing efficiency is improved compared with the premise. If the system leaks or leaks slightly, the density of the fire extinguishing agent is high, and the density of the nitrogen is low, so that the nitrogen can be preferentially discharged from the small holes at the root part of the siphon pipe until the pressure is reduced to the normal pressure state, only the nitrogen is lost in the whole process, and the fire extinguishing agent is hardly lost. And in subsequent maintenance, the system can be put into use again only by replacing the sealing piece and repressurizing the nitrogen. The maintenance is simple and fast, and the reliability is higher.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
