Description
(1) technical field
The utility model relates to a kind of light-duty portable fire extinguisher.
(2) background technology
At present, more hand fire extinguisher occurring on the domestic market is the pressure storage type fire extinguisher, generally be placed in the fixed-sites such as supermarket, hotel, market standby, the steel cylinder that bears pressure because of its inside is directly exposed in the external world, and the seal request degree of this fire extinguisher is very high, is subjected to ectocine, as temperature fluctuation, motion vibrations, or sealing ring is aging etc., and reason causes internal pressure to reduce, and influence the use of fire extinguisher, needs the fixed time test maintenance.
Existing gas bomb fire extinguisher is not high to seal request, but the profile of its built-in gas bomb is bigger, causes operating mechanism and valve body structure bigger, generally mostly is the above specification of 4kg, is not suitable for portable operation; Gas cylinder is punctured moment during fire extinguishing, as does not have enough big space for CO
2Expand, set off an explosion poor stability easily.
(3) summary of the invention
The deficiency that hand fire extinguisher seal request height in the prior art, shock resistance are poor in order to overcome, volume is big, need fixed time test to safeguard, the utility model provide that a kind of seal request is not high, shock resistance is good, volume is less, need not the light-duty portable fire extinguisher that fixed time test is safeguarded.
The technical solution of the utility model is:
A kind of light-duty portable fire extinguisher, comprise the can powder extinguishing agent steel cylinder, be located at storing liquid CO in the steel cylinder
2Small gas cylinder, the valve body affixed with the steel cylinder mouth, be provided with spanner and safeties in the described valve body, be provided with the vertical valve stem slides passage and the extinguishing chemical injection channel of level in the described valve body, valve stem slides passage and extinguishing chemical injection channel interconnect, be provided with valve rod in the valve stem slides passage, be provided with sealing device between valve rod top and the valve body, the bottom of valve rod is connected with little pricker, described valve rod top cooperates with spanner, the bottom be fixed in valve body on the moral head cooperate, described moral head bottom is socketed on the small gas cylinder bottleneck, also is provided with and valve rod in the moral head, the spring that small gas cylinder offsets.
Described valve body lower portion and powder absorbing pipe are affixed, and the powder absorbing pipe inwall is provided with brace rod, and described small gas cylinder is placed on the brace rod, and a moral sidewall has for CO
2The gas port that flows out, described gas port communicates with powder absorbing pipe, and valve rod is in primary importance, and extinguishing chemical injection channel and powder absorbing pipe are closed, and valve rod is in the second place, and the extinguishing chemical injection channel is communicated with powder absorbing pipe.
Described powder absorbing pipe bottom offsets with the steel cylinder bottom, and the powder absorbing pipe bottom is provided with and prevents that a large amount of powder extinguishing agents from entering the bottom plug in the powder absorbing pipe, leaves between bottom plug and the powder absorbing pipe for CO
2The gap that gas passes through.
Described safeties comprise the safety fastener that is provided with draw ring and the fixing safety plug of safety fastener, and described spanner is rotatably installed on the valve body, and spanner has bending, and bending is provided with the track for the safety fastener pulling, and bending cooperates with valve rod.
Be provided with the O RunddichtringO between described moral head and the valve rod.
The operation principle of the light-duty portable fire extinguisher of the utility model is as follows: operating personnel are with pulling draw ring, firmly break safety plug, safety fastener forces spanner to clockwise rotate under the effect of pulling force, the power of level is through the rotational transform one-tenth active force vertically downward of spanner, the promotion valve rod presses down, valve rod is in the second place, and the head of the pricker bump small gas cylinder that dashes down also punctures small gas cylinder, inner liquid CO
2Outwards expand rapidly and vaporize, at this moment, spring is up lifted valve rod together with pricker under the effect of tension force, and it is that valve rod is in primary importance that valve rod is returned to the home position, and valve rod has been closed extinguishing chemical and CO
2The passage of gas ejection, liquid CO
2By pore along in the powder absorbing pipe to steel cylinder bottom expansion, be full of whole steel cylinder rapidly through bottom plug, fire extinguisher was in and can both sprays powder extinguishing agent at any time and put out a fire this moment.Spanner is wrenched with hand in bottom away from the nearly 2 meters position alignment flame in ground that catches fire, and this moment, valve rod was in the second place, has promptly opened the passage that extinguishing chemical sprays, and the fire extinguisher that swings this moment can sweep fire extinguishing.
The beneficial effect of light-duty portable fire extinguisher described in the utility model mainly shows: 1, compact conformation, volume is little, seal request is not high, shock resistance is good, need not fixed time test safeguards; 2, small gas cylinder is installed in the powder absorbing pipe, and design has enough spaces for CO
2Expand, can not set off an explosion, security is good.
