The cylinder body is filled with dry powder and high pressure gas; the injection orifice of the cylinder body is connected with a connecting pipe with a closed end; the connecting pipe is provided with a bottle body in a sealing way; the bottle body stretches into the closed end of the connecting pipe; the sealed end in the connecting pipe is provided with a small needle through a spring; the needle head of the small needle is inserted into the bottle body and is close to a high pressure air bag arranged in the bottle body; the rest part in the bottle body is filled with pigment powder; the other end of the bottle body is provided with a bottle opening; and the bottle opening is sealed and covered by a thin film. When pressure in the cylinder body is lower than a safe valve, the spring drives the small needle to puncture the high pressure air bag in the bottle body, and compressed air in the high pressure air bag is gathered and expanded to push the pigment powder in the bottle body to break through the thin film at the bottle opening and to cover on the surface of the fire extinguisher, so that people can find that the dry powder fire extinguisher has a failure far away to inflate or replace the fire extinguisher in time.
Description
Technical field:
The present invention relates to a kind of fire extinguisher that can show disabled status, and be particularly related to a kind of dry powder extinguisher that can show disabled status.By intuitively showing the device of dry powder extinguisher disabled status at a distance in existing dry powder extinguisher outer setting one, so that in time check out the fire extinguisher that loses fire-extinguishing function concurrently, and it is inflated, make it to have again fire-extinguishing function concurrently.
Background technology:
Dry powder extinguisher be mainly used to put out a fire to save life and property flammable liquid, fuel gas and electrical equipments such as oil and products thereof, organic solvent from the beginning of fire.Dry powder extinguisher is to be power with high-pressure carbon dioxide gas or nitrogen, ejects the utensil of powder extinguishing agent.Mainly form by cylindrical shell, cover, spraying system and opener etc.
What fill in the dry powder extinguisher is powder extinguishing agent.Powder extinguishing agent is be used to put out a fire dry and the attritive powder that is easy to flow, by inorganic salts with fire extinguishing effectiveness and minor amounts of additives drying, pulverize, mix the micro-solid powder constituent.It is a kind of extinguishing chemical of being used widely in fire-fighting, and is mainly used in the fire extinguisher.Except that the special-purpose dry powder chemical extinguishing chemical of the metal fire of putting out a fire to save life and property, powder extinguishing agent generally is divided into Bc powder extinguishing agent and ABC dry powder two big classes.The physics that powder extinguishing agent mainly contacts with flame, takes place when mixing by the dust cloud that sprays under the gas-pressurized effect, chemical action fire extinguishing.In addition, also have part to dilute the effect of oxygen and cooling.
But dry powder extinguisher also can lose efficacy, and the dry powder extinguisher actual effect mainly is because the pressure of internal pressure gas reduces.When the fire extinguisher internal pressure reduced, powder extinguishing agent just can not spray internally, and fire extinguisher just loses the function of fire extinguishing like this.If need make fire extinguisher have the function of fire extinguishing again, need inflate it, powder extinguishing agent can be sprayed up to pressure inside.
In order to show whether dry powder extinguisher lost efficacy, a Pressure gauge is housed usually, on the cover on the dry powder extinguisher to show the dry powder extinguisher pressure inside.But this type of Pressure gauge is very little, need closely see just and can see clearly, so general easy ignorance once when need using, find that just dry powder extinguisher had lost efficacy, brings hidden danger to fire safety.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of fire extinguisher that can show disabled status, by can intuitively show the device of dry powder extinguisher disabled status at a distance in existing dry powder extinguisher outer setting one, in time change dry powder extinguisher with reminds people.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
The fire extinguisher that can show disabled status, comprise cylindrical shell and the opener, the Pressure gauge that are arranged on the cylindrical shell jet, in described cylindrical shell, be filled with dry powder and gases at high pressure, it is characterized in that, on described cylindrical shell jet, connect one one end sealing, the adapter that communicates in the other end and the cylindrical shell is sealed and installed with a bottle in described adapter, bottle stretches into the end sealing in taking over; An end of sealing is equipped with a little pin by a spring in taking over, the syringe needle of little pin inserts in the bottle and approaches to be arranged on the interior high-pressure gasbag of bottle, remainder is filled with the pigment powder in bottle, and the other end of bottle has bottleneck, covers with diaphragm seal on the bottleneck.If both sides' reason
Described bottle and described adapter intersect vertically.
Operation principle of the present invention is: when the pressure in the cylindrical shell is lower than safety value, spring drives the high-pressure gasbag in the broken bottle of stylet, compressed air in the high-pressure gasbag gathers expansion, promote the film that the interior pigment powder of bottle breaks through bottleneck, cover the surface of fire extinguisher, people are far so just can find that this dry powder extinguisher lost efficacy, and in time inflates or changes.If inflate in cylindrical shell, when the pressure in the cylindrical shell was higher than safety value, Compressed Gas promoted little pin and retreats, and added new high-pressure gasbag and pigment powder again in bottle, covered bottleneck with diaphragm seal and got final product.
The present invention is by setting up a bottle and little pin on existing dry powder extinguisher, filling high-pressure gasbag and pigment powder in bottle when dry powder extinguisher pressure reduces, can intuitively show the disabled status of fire extinguisher, and people are far just to be observed, very convenient.The annex cost of setting up is not high, economic and practical.
