As a specific example, the element further comprises level detection means for detecting the level of liquid in the container 1.

Fig. 4 is a schematic position diagram of a liquid level detection device provided by an embodiment of the present disclosure, in which a liquid level detection device 5 is installed on a container 1, and an installation position of the liquid level detection device 5 is reserved in the container 1.

Fig. 5 is a schematic position diagram of another liquid level detection device provided in the embodiment of the present disclosure, where the liquid level detection device 5 is independent of the container 1, and when detection is needed, the handheld liquid level detection device 5 approaches the container 1 to detect the liquid level in the container 1.

The utility model provides a fire extinguishing agent bottle group uses outer storage high-pressure gas to promote the fire extinguishing agent through the admission valve and goes out liquid valve blowout work, and admission valve and play liquid valve all use the check valve, and the leakproofness is good, and the maintenance work load is little, only need regularly survey the liquid level look over the leakproofness of container 1 can, through the regular maintenance that external hand-held type liquid level detection device or fixed mounting all can conveniently realize fire extinguishing agent bottle group in the liquid level detection device of container 1. The liquid level detection device can use various existing devices capable of detecting liquid level.

Fig. 6 is a schematic structural view of another easy-maintenance external pressure-storage perfluorohexanone fire extinguishing agent bottle set provided by the embodiment of the disclosure, as shown in fig. 6, the components further include a liquid delivery pipe 3, one end of the liquid delivery pipe 3 is fixedly connected to the one-way liquid outlet valve 2, and the other end of the liquid delivery pipe extends into the bottom of the container 1 and is used as a delivery channel of a fire inhibitor.

If the one-way liquid outlet valve 2 and the one-way air inlet valve 4 are positioned on the same side of the container 1, when the fire extinguishing agent bottle group works, high-pressure gas enters the container 1 through the one-way air inlet valve 4, the gas pushes the fire suppressant to move towards the other side, and the fire suppressant can directly reach the one-way liquid outlet valve 2 and is sprayed out through a channel of the one-way liquid outlet valve 2 by arranging the liquid conveying pipe 3 which is directly communicated with the bottom of the other side of the container 1 on the one-way liquid outlet valve 2.

As a specific example, the container 1 may use a gas cylinder. Fig. 7 is a gas cylinder provided in an embodiment of the present disclosure. Further, an anti-corrosive coating 101 is provided on the inner surface thereof, the coating being compatible with a fire suppressant, such as perfluorohexanone, for example, such as an epoxy resin coating. Optionally, the parts in the above embodiments are mounted on the cylinder head.

The gas cylinder is a conventional pressure container, and is used for the fire extinguishing agent cylinder group, so that the conventional equipment facilities matched with the gas cylinder, such as production, storage, transportation and the like, can be fully utilized, new equipment for matching the novel fire extinguishing agent is not required, and the development and construction cost of the equipment facilities matched with the novel fire extinguishing agent is greatly reduced. Meanwhile, although the container 1 does not need to bear pressure in the processes of production, storage, transportation, use and the like, in the spraying link, the material of the container 1 can bear certain pressure due to the need of high-pressure gas driving, and the material needs to be hard and can bear certain pressure, such as steel.

The gas cylinder is generally used for containing gas, liquid fire inhibitors such as perfluorohexanone and the like are contained in the gas cylinder, long-term storage is guaranteed, the material of the gas cylinder does not react with the fire inhibitors such as perfluorohexanone and the like, and the existing research shows that perfluorohexanone and common metal materials such as carbon steel, copper, aluminum, stainless steel and the like are non-corrosive, but the test time is generally short, and the material compatibility of the immersion test of 3-6 months is not strong enough for the service life of a fire-fighting product which is about to be 20 years (the service life of a welding container is referred). But it is not practical for an enterprise or related research institution to perform actual testing. Therefore, by additionally arranging the corrosion-resistant coating 101 in the container such as the gas cylinder and the like, for example, an epoxy resin coating which is widely applied at present, the gas cylinder can be well protected from being corroded by fire inhibitors such as perfluorohexanone and the like, and the purity and the fire extinguishing efficiency of the perfluorohexanone are kept.

In addition, based on the structural characteristics of the gas cylinder, the one-way liquid outlet valve 2, the one-way gas inlet valve 4 and/or the liquid level detection device can be arranged on the gas cylinder end socket, so that the structure is compact, the space is saved on the other hand, and the facilities of production, storage, transportation and the like of the existing gas cylinder are fully utilized.

As a specific example, on the basis of the above-mentioned embodiment, as shown in fig. 7, a plurality of mounting seats 102 are provided on the container 1, for example, a gas cylinder, and the above-mentioned components can be connected with the mounting seats in a sealing manner. Optionally, the part is connected with the mounting seat in a sealing mode through threads and epoxy resin glue.

In order to facilitate the installation of the aforementioned components after the container 1 is filled with a fire suppressant, such as perfluorohexanone, the container 1 is provided with a mounting 102 in advance, and the components are hermetically mounted to the corresponding mounting after filling, such as by welding. Optionally, the part is detachably connected with the mounting seat in a threaded manner, and the thread is sealed by using high polymer glue such as epoxy resin glue, so that on one hand, factors such as reduction of sealing quality caused by aging due to sealing by using elastic materials such as conventional plastics are avoided, and on the other hand, the glue does not chemically react with fire inhibitors such as perfluorohexanone. Moreover, the detachable connection is convenient to operate, on the other hand, after the fire inhibitor is sprayed, the whole device can be conveniently recycled, parts can be easily taken down from the container 1 only through hot detachment, then the fire inhibitor is canned again for packaging and leaving factory, and waste is avoided.

As a specific example, the parts to be placed in contact with the fire suppressant are made of a corrosion-resistant metal material.

The anti-corrosion coating arranged inside the container 1 can greatly reduce the risk of reducing use efficiency caused by corrosion deterioration caused by annual storage of fire inhibitors such as perfluorohexanone, parts of the parts which are possibly contacted with the fire inhibitors are made of anti-corrosion metal such as aluminum alloy or copper alloy, no rubber or plastic material is used, the corrosion effect and the aging effect of non-metallic materials are avoided, and the fire inhibitors are guaranteed to be as pure as the fire inhibitors produced after annual storage.

Furthermore, the easily-maintained external pressure storage perfluorohexanone fire extinguishing agent bottle group is arranged to be filled in a fire inhibitor such as a perfluorohexanone manufacturing plant, a fully-closed structure is formed after filling, the reduction of the purity of perfluorohexanone in a circulation link is avoided, and the water content of perfluorohexanone in the fire extinguishing agent bottle group is controlled to be consistent with the delivery standard of a perfluorohexanone production plant. Research shows that the doped perfluorohexanone can lead the liquid to be acidic, and the doped perfluorohexanone can corrode the metal after being contacted with the metal for a long time.
