Abstract
The utility model relates to a ramming type powder fire-extinguishing rod, which belongs to the technical field of fire-extinguishing. The ramming type powder fire-extinguishing rod retains a cylinder body, a spraying cover, a gas storage cylinder, a thimble, a rear lid plug and a safety ring of the existing fire-extinguishing rod. The ramming type powder fire-extinguishing rod is characterized in that a cylinder body is provided with a propeller; the tail end of a rear lid plug is sheathed with a rear cover. Thereby, the fire-extinguishing efficiency and safety of the ramming type powder fire-extinguishing rod are improved. The ramming type powder fire-extinguishing rod can carry out fire-extinguishing under the state of plunging, up or horizontal spraying. The ramming type powder fire-extinguishing rod can not harden when dry powder is stored for a long time. Besides, the residual rate of the dry powder is over 3%. The ramming type powder fire-extinguishing rod can be used for first burning fire of oil products, petroleum products, organic solvent, paints and general solid articles in dwellings, workplaces, vehicles and ships.
Description
The utility model relates to a kind of impacting type dry-chemical fire extinguishing rod, belongs to fire-fighting domain.
At present, the dry-chemical fire extinguishing rod that occurs on the market is not to open inconvenience, is exactly that left powder amount is too many.China's Patent Gazette for Utility Models the 3rd is rolled up on No. 42 and is disclosed a kind of " light-duty Fire extinguishing club ", its purpose is to be used to the oils of putting out a fire to save life and property, organic molten system, fuel gas and circuit arrangement and general solid matter from the beginning of fire, its formation comprises stack shell, spray cover, valve body, steel cylinder, thimble, back capping plug etc.; It is characterized in that having in the stack shell piston with holes, between piston and back capping plug one spring is arranged, its weak point is: one. the long-term pressurized of spring (being generally 3-5) can make elasticity weaken, and stretchs out length and shortens, thereby can not guarantee that left powder amount is less than 5%; Two. annual normal maintenance is dangerous, and in the assembling and dissembling process, spring easily ejects part and hurts sb.'s feelings; Three. extinguishing chemical--the long-term pressurized of dry powder, easily harden, left powder amount is increased, the more important thing is and can not put out from the beginning of fire timely and effectively.
The purpose of this utility model is just in order to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of esy to use, safe and reliable, surplus powder rate to be lower than 3%, the also unlikely impacting type dry-chemical fire extinguishing rod that hardens of long-term storage dry powder.
The purpose of this utility model is achieved in that impacting type dry-chemical fire extinguishing rod comprises stack shell, the spray cover, gas cylinder, thimble, back capping plug, safety diaphragm, damp-proof membrane and relieving ring, it is characterized in that having in the stack shell one to push away the powder device, back capping plug afterbody is socketed with a back cover, push away the powder device and mainly play guiding, isolate, push away the effect of powder, its end is a cylinder with cover, cover the aperture that is provided with more than 3, wherein, centre bore plays a part to dust, the aperture of both sides plays a part to stir and loose dry powder, push away on the groove of powder device and be socketed with a sealing ring, mainly play the prevention air-flow and flow to dry powder along the stack shell inwall.Pushing away the powder device is made by nonmetallic materials such as plastics, rubber, timber etc.
Accompanying drawing is the structural representation of the utility model impacting type dry-chemical fire extinguishing rod.
Below just closing accompanying drawing is further described concrete structure of the present utility model and operation principle.
Impacting type dry-chemical fire extinguishing rod is by stack shell 6, what be mounted in it pushes away powder device 7, be enclosed within the sealing ring 8 that pushes away on the powder device, back capping plug 5 that spins with the stack shell two ends respectively and spray cover 11 with the gas cylinder 4 that the back capping plug spins, are attached to the safety diaphragm 3 of gas cylinder bottleneck, be contained in the thimble 2 in the capping plug centre bore of back, be stuck in the relieving ring 12 at bonnet middle part, on relieving ring and with back cover 1 that the bonnet plug sleeve connects, be stuck in link 13 in the back cover hole, and the damp-proof membrane 10 that is attached on the spout 9 constitute.
Operation principle of the present utility model and use as following:
At first, pull out relieving ring 12, with palm bump back cover 1, with 2 motions of compressing thimble, pierce through the safety diaphragm 3 of gas cylinder 4 upper ends, gases at high pressure are discharged, because thimble 2 and 5 sealings of back capping plug, like this, releasable gas just can only enter the epicoele of stack shell 6 along the inclined hole of back capping plug 5, and enter in the dry powder of stack shell 6 lower ends by the aperture that pushes away on powder device 7 bottom end covers, about 1-3 second, stack shell 6 bottom pressure constantly increase, and cause the damp-proof membrane 10 of spout 9 lower ends breakdown, so dry powder just sprays from spout 9 high speeds.Flow through a pressure loss arranged when pushing away aperture on the powder device 7 because dry powder constantly outwards sprays gas in addition, thus the internal pressure that the powder end is arranged at stack shell all the time less than no powder end, this pressure differential driving pushes away powder device 7 near dry powder just, all sprays until dry powder.What be worth emphasizing is can open the passage that dry powder flows by the air-flow that pushes away powder device bottom end cover centre bore, plays the effect of injection, and the aperture on both sides can make dry powder float and play the effect of secondary injection.Therefore, dry powder can pass spout 9 smoothly and promptly until whole ejections.
The utility model under assurance product safety reliable premise, simplifies the structure in design process to greatest extent, selects domestic existing standard section bar, working of plastics and rubber parts etc. for use, has simplified technology, has reduced cost.
The utility model compared with prior art has simple in structure, easy to use, with low cost, safe and reliable, surplus powder rate is low, even if long-term storage, dry powder is the unlikely characteristics such as harden also, can shoot downward, face upward penetrate and the flat fire state under put out a fire, be widely used in various dwelling houses, the yard oils of putting out a fire to save life and property in vehicle, the boats and ships in one's power, oil product, organic solvent, paint and general solid matter from the beginning of fire.
