Description
Technical field
The present invention relates to a kind of fire-fighting fire extinguishing equipment, relate in particular to the plain water fire extinguisher that can be used to put out charged burning things which may cause a fire disaster.
Background technology
Clear water has lower viscosity at normal temperatures, higher heat endurance, and bigger density and higher surface brute force, it mainly relies on cooling and smothering action to put out a fire.Every kg water is heated to boiling point and complete carburation by evaporation from normal temperature, can absorb the heat of 2593.4KJ, is that other any extinguishing chemical is incomparable; To be vaporized the steam that the back forms be inert gas to water in addition, and volume will expand 1700 times, and the steam after the expansion will occupy the space, combustion zone, dilute combustion thing ambient oxygen content, and the obstruction fresh air enters the combustion zone, reaches the purpose of fire smothering.Also have the surface area of water droplet and droplet to increase greatly, strengthened the heat exchange action between water and the fire, from and strengthened its cooling and smothering action.Therefore, clear water is a kind of highly effective, wide material sources, inexpensive free of contamination clean type extinguishing chemical.
Yet,, especially in the putting out of high-tension electricity burning things which may cause a fire disaster, human body is had harmful and dangerous at charged burning things which may cause a fire disaster because clear water has certain electric conductivity.According to test, human body resistance is 1000 Europe, the people is with regard to electric shock feeling when being 1mA through body current, when clear water puts out burning things which may cause a fire disaster, continuous direct current water column becomes the electric conductor between human body and burning things which may cause a fire disaster, produces leakage current by the direct current water column on human body, and charged burning things which may cause a fire disaster voltage is high more, the water resistance rate is more little, and its safety hazard is high more.But in reality fire extinguishing, need or other reason can't be cut off the electricity supply because of producing sometimes, or meet when still having higher residual voltage after cutting off the electricity supply, must charged fire extinguishing.CO is still mainly adopted in putting out a fire to save life and property of present charged burning things which may cause a fire disaster
2, 1211 and dry powder etc. have the extinguishing chemical of enough insulating capacities to put out a fire.The carbon dioxide extinguisher extinguishing grade is low, and easily causes frostbite even make us death by suffocation; And 1211 extinguishing chemicals are a kind of very strong materials that damage the ozone layer, and are eliminated and forbid; Dry powder extinguisher is to carry out chemical reaction after heat is met on the comburant surface, can form on the comburant surface to have corrosive crystalloid material, causes the corrosion of charging equipment, and forms environmental pollution.Therefore, people always seek to put out as extinguishing chemical with clear water the approaches and methods of charged burning things which may cause a fire disaster.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can put out charged source and intermittent type plain water fire extinguisher nozzle safe in utilization with clear water.
In order to solve the problems of the technologies described above, intermittent type plain water fire extinguisher nozzle of the present invention comprises nozzle body, is installed with interrupted diversion seat in described nozzle body, is provided with a diversion column installing hole on this interrupted diversion seat at least; Be provided with in the cup position, the end of the diversion column installing hole of cup-shaped structure and eject the water hole, described diversion column installing hole with eject the eccentric distance e=0.1～3mm in water hole; In the diversion column installing hole, be provided with rotating diversion column versatilely, be provided with a spiral stream guidance groove on the surface of this rotating diversion column at least, the pitch angle alpha will of spiral stream guidance groove=30 °～60 °; The distance of the rotating diversion column axial line of bottom land distance of spiral stream guidance groove is less than the described radius that ejects the water hole.
After adopting said structure, owing on the interrupted diversion seat in nozzle body rotating diversion column is installed, and rotating diversion column is provided with the spiral stream guidance groove, when stamping out a fire, the spiral stream guidance groove of High-Pressure Water on rotating diversion column and eject the water hole and spray to charged burning things which may cause a fire disaster, High-Pressure Water produces the tangential motive force of convection rotary type diversion column on the spiral stream guidance groove, make rotating diversion column produce rotatablely moving around self axle center, the rotating diversion column of rotation makes the spiral stream guidance groove on it and ejects the connected sum disconnection that occurs between the water hole at interval, the ejection current form interrupted spurting, thereby the leakage current of thoroughly having blocked charged burning things which may cause a fire disaster is through the current post, hydraulic giant nozzle and human body are gone into ground, avoided the generation of electric shock security incident, realized putting out charged fire with clear water, it is effective not only to put out a fire to save life and property, and safe in utilization.Again since the eccentric diversion column installing hole that is provided with eject the water hole eccentric throw and be chosen in 0.1～3.0mm, when rotating diversion column places the diversion column installing hole, and when having High-Pressure Water to pass through, High-Pressure Water promotes rotating diversion column and rotates, the automatic disconnection and the connection of water stream channel have been realized easily, blocked leakage current flowing through current, and the selection of this eccentric throw can guarantee that the ejection current have best jet atomization effect and jet length far away, has further strengthened the fire extinguishing effect and the usage safety performance of water.Also because pitch angle alpha will=30 of spiral stream guidance groove °～60 °, this helical angle can guarantee under the situation of difference fire extinguishing water flow pressure enough tangential motive forces are arranged all, to guarantee the turn of rotating diversion column, makes it the water state that goes out that always keeps interrupted.
Preferred implementation of the present invention, described diversion column installing hole diameter D and ratio D/d=2 ~ 3 of ejecting the water hole diameter d.This physical dimension water that can guarantee preferably to put out a fire to save life and property always is spray water and sprays to charged burning things which may cause a fire disaster.
Another preferred implementation of the present invention, described interrupted diversion seat is provided with 3 ~ 10 diversion column installing holes, and the diversion column mounting hole site is on same circumference.The cylinder of described rotating diversion column is provided with 2 ~ 5 spiral stream guidance grooves.This structure not only keeps jet atomization effect preferably, and stronger water yield is arranged, to adapt to the effect of putting out of the different intensity of a fire.
