Description
【考案の詳細な説明】 （産業上の利用分野） この考案は、水系の消火剤を放射するノズルに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a nozzle that emits a water-based fire extinguishing agent.
（従来の技術） 水系の消火液で油火災を消火するため、及び放射液流の
電気伝導性を無くすために、ノズルから出る消火液を連
続しない粒子にして散らして放射する必要がある。(Prior Art) In order to extinguish an oil fire with a water-based fire extinguishing liquid and to eliminate the electric conductivity of a radiant liquid flow, it is necessary to disperse the fire extinguishing liquid into discontinuous particles and radiate them.
消火液を粒子状に放射するには、ノズルに螺旋状の液流
にする機構を設け、放射液に回転力を与え遠心力で散ら
すようにしている。In order to radiate the fire extinguishing liquid in the form of particles, the nozzle is provided with a mechanism for forming a spiral liquid flow, and a rotating force is applied to the radiating liquid to disperse it by centrifugal force.
（考案が解決しようとする問題点） 放射液流に回転力を与えるノズルは、放射液が大きく広
がり放射距離が短くなって好ましい消火性能が得られな
い。(Problems to be solved by the invention) In a nozzle that applies a rotational force to a radiant liquid flow, the radiant liquid spreads widely and the radiating distance becomes short, so that preferable fire extinguishing performance cannot be obtained.
ノズルの出口の前にオリフィスを設けると、出口から出
る放射液流は完全な棒状とならず、乱れて粒子となって
散ることがわかっている。しかしながら粒子は平均的で
なく求めるノズルにはならない。It has been found that when an orifice is provided in front of the outlet of the nozzle, the radiant liquid flow exiting the outlet does not have a perfect rod shape but is turbulently dispersed as particles. However, the particles are not average and will not be the desired nozzle.
この考案は特殊な水系の消火器に採用して、消火性能を
充分発揮できるノズル、すなわち消火液の放射拡度が５
°内外で、かつ平均的な粒子となるようなノズルを開発
することを目的とするものである。This device is applied to a special water-based fire extinguisher, and the nozzle that can fully show fire extinguishing performance, that is, the radiation spread of the fire extinguishing liquid is 5
° The purpose is to develop a nozzle that produces an average particle inside and outside.
（問題点を解決するための手段） この考案を、図面に示す実施例によって説明する。(Means for Solving Problems) This invention will be described with reference to an embodiment shown in the drawings.
第１図のノズルにおいて、消火液の出口１より順に液流
を絞る第１のオリフィス２、第２のオリフィス３を配置
してある。In the nozzle of FIG. 1, a first orifice 2 and a second orifice 3 that restrict the liquid flow in order from the outlet 1 of the fire extinguishing liquid are arranged.
４は先端部、５は連結部、６はホースで消火器（図示省
略）に連結してある。Reference numeral 4 is a tip portion, 5 is a connecting portion, and 6 is a hose connected to a fire extinguisher (not shown).
（作用） 消火液はホース６より第２のオリフィス３によって流れ
が乱れ、さらに第１のオリフィス２によって乱れ、出口
１より放射される。(Operation) The flow of the fire-extinguishing liquid is disturbed by the second orifice 3 from the hose 6, further disturbed by the first orifice 2, and emitted from the outlet 1.
消火液は５°内外の狭い広がりで粒子となって飛び放射
する。The fire-extinguishing liquid flies and radiates as particles with a narrow spread of 5 ° inside and outside.
（実施例） 第１図はこの考案の一実施例で、先端部４には出口１
を、先端部４とこれに連結する連結部５との間にはオリ
フィス２を、そして連結部５の基部にはオリフィス３を
それぞれ設け、連結部５はホース６に連結されている、 出口１とオリフィス２との間には、オリフィス２より径
の大きい管部７をかつ短い間隔で、またオリフイス２と
３との間には両オリフィス２、３より径の大きい管部
８、９をかつ管部７より数倍以上の間隔としてある。(Embodiment) FIG. 1 shows an embodiment of the present invention, in which a tip 1 has an outlet 1
An orifice 2 is provided between the tip portion 4 and the connecting portion 5 connected to the tip portion 4, and an orifice 3 is provided at the base portion of the connecting portion 5, and the connecting portion 5 is connected to the hose 6. Between the orifice 2 and the orifice 2, a pipe portion 7 having a diameter larger than that of the orifice 2 is provided at a short interval, and between the orifices 2 and 3, pipe portions 8 and 9 having a diameter larger than those of the orifices 2 and 3 are provided. The interval is several times or more than the tube portion 7.
具体的に出口１とオリフィス２、３の口径比は1:1.07:
1.25、出口１からオリフィス２、３への間隔比を1:15と
したとき、消火液の放射流の拡度は５°、粒子は平均的
で、放射距離は連続棒状の放射と変わらない。Specifically, the diameter ratio of the outlet 1 to the orifices 2 and 3 is 1: 1.07:
When the distance ratio from the outlet 1 to the orifices 2 and 3 is 1.25, the spread of the radiant flow of the fire extinguishing liquid is 5 °, the particles are average, and the radiating distance is the same as the continuous rod-like radiation.
出口１とオリフィス２、３の口径比は上述する比に限ら
ず整数比でないことが望ましい。The diameter ratio of the outlet 1 to the orifices 2 and 3 is not limited to the above-mentioned ratio, and it is desirable that it is not an integer ratio.
出口１、オリフィス２、３への間隔比は上述する比に限
らず整数比であれば良い。The interval ratio to the outlet 1 and the orifices 2 and 3 is not limited to the above-mentioned ratio and may be any integer ratio.
オリフィス２は筒体10の端面に穴のあいた形状である
が、単なる板形状でも良い。The orifice 2 has a shape in which a hole is formed in the end surface of the cylindrical body 10, but it may be a simple plate shape.
