Abstract
The present invention relates to gas fire-fighting fire extinguishing equipment field, the nozzle of a kind of Special automatic extinguisher for chemical laboratory.The present invention, when automatic fire extinguisher starts, effectively reduces the amount of spurting of gas extinguishing agent, it is to avoid bigger due to the too fast sound of flow velocity during using, and makes the gas extinguishing agent gaseous state persistent period longer, so that extinguishing effect is more preferably；Simultaneously by controlling the flow velocity of gas extinguishing agent, its blowing down pressure of equal control, thus effectively protect the equipment in protection zone.
Description
Technical field
The present invention relates to fire-fighting fire extinguishing equipment field, particularly relate to the nozzle of a kind of Special automatic extinguisher for chemical laboratory.
Background technology
The most common gas extinguishing agent nozzle, most employing stainless steels, and the outward appearance bodily form is bigger, if for chemical laboratory fire-fighting fire extinguishing, will there is a following drawback: the chemicals of laboratory easily nozzle to stainless steel causes corrosion, and nozzle volume is unfavorable for more greatly the stealthy installation requirement that laboratory modernizes.If but reduced nozzle volume, will be unable to could be by complete for the injection of fire-suppressant gas preparation in 15 seconds that usual specification specifies.The time that fire-suppressant gas is spurted by the size in the most existing aperture, the pressure spurted, liquid when spurting are held time and all be there is adverse effect.
Summary of the invention
The invention aims to overcome the shortcoming of prior art, it is provided that the nozzle of the brand-new design of a kind of Special automatic extinguisher for chemical laboratory.
The technical scheme of the nozzle of a kind of Special automatic extinguisher for chemical laboratory of the present invention is: include gas extinguishing agent steel cylinder, bottle head electromagnetic valve, bottle valve, high direct voltage flexible pipe, pressure piping, threeway, region distributing valve, nozzle, gas extinguishing agent steel cylinder connects bottle head electromagnetic valve and bottle valve, bottle head electromagnetic valve controls gas extinguishing agent steel cylinder release fire-suppressant gas, the hose connection pressure piping of high direct voltage, threeway is connected pressure piping and high direct voltage flexible pipe respectively with region distributing valve, high direct voltage flexible pipe is connected with nozzle, described high direct voltage flexible pipe one has two, it is characterized in that flexible pipe caliber is φ 10.
The nozzle of a kind of Special automatic extinguisher for chemical laboratory of the present invention, specific implementation process is: after automatic fire extinguisher sensing starts, start bottle head electromagnetic valve, the gas making gas extinguishing agent steel cylinder enters high direct voltage flexible pipe by bottle valve, hence into pressure piping, is automatically guided by region distributing valve by threeway, enter the high direct voltage flexible pipe being connected with nozzle, thus arrive nozzle, spurt, finally carried out guiding by the kuppe in nozzle and complete fire extinguishing.The technical program be characterized mainly in that employing big-diameter pipeline, high direct voltage flexible pipe caliber and nozzle caliber are φ 10, use such design, when gas extinguishing agent spurts, can decrease the amount of vaporization of gas extinguishing agent, thus extend the extinguishing chemical gaseous state time.The jet hole simultaneously using 6 apertures to be φ 5, effectively prevent and cause sound bigger owing to flow velocity is too fast during use, make gas extinguishing agent gaseous state hold time long, thus reach optimal extinguishing effect.And make gas extinguishing agent blowdown time be effectively controlled in 15 seconds, control blowing down pressure efficient balance, make to be turned over the equipment in protection zone during gas extinguishing agent operation.
The nozzle of a kind of Special automatic extinguisher for chemical laboratory of the present invention, it is characterised in that be made up of jet hole, gas flow guiding cover, direct current copper pipe, fixed panel, hold-doun nut.Described jet hole, it is characterized in that selected material is hollow pure copper tube, bottom has the spray orifice that 6 apertures are 6* φ 5, the a diameter of φ of jet hole bottom external 17, a length of 15 millimeters of the jet hole limit wing, below the wing of jet hole limit from jet hole distance from bottom be 18 millimeters, above the wing of jet hole limit from jet hole distance from bottom be 36 millimeters, above the wing of jet hole limit from jet hole distance from top be 10 millimeters, jet hole top is 37 millimeters from the distance of spray orifice, jet hole hollow total length is 43 millimeters, jet hole hollow inside diameter is φ 10, the a diameter of φ of jet hole top outer 16.
