Description

미스트 분무 기능을 갖는 화재진화용 관창{Nozzle for fire fighting with mist spray function}Nozzle for fire fighting with mist spray function}

본 발명은 미스트 분무 기능을 갖는 화재진화용 관창에 관한 것으로서, 더욱 상세하게는 화재진화용 관창에 있어서, 방수관의 단부에 미분무를 위한 급수를 위하여 미분공급구를 등 간격으로 형성하여 구비한 미분무공급관과 방수관의 방사선택수나사부에 수밀이 유지되도록 나사결합되게 구비되는 방사선택노브, 미분하우징에 소방수를 미분무 분부되게 구비되는 미분노즐부, 미분하우징의 내부에 결합되어 미분무공급관 내부로 삽입되어 소방수의 미분무공급을 제어할 수 있도록 미분밸브공을 등간격으로 형성하여 구비한 미분밸브관으로 구성하여서, 방사선택노브의 회전 조작만으로 미분무와 미분무/직사, 직사 및 분사 방수가 용이하게 이루어지도록 함을 목적으로 한 것이다.The present invention relates to a fire extinguishing nozzle having a mist spray function, and more particularly, in a fire extinguishing nozzle, a fine powder supply port is formed at equal intervals to supply water for fine spray at the end of a waterproof pipe. A radiation tack knob provided to be screwed together to maintain watertightness on the radioactive water threaded part of the non-supply pipe and the waterproof pipe, a mist nozzle part provided to finely spray fire-fighting water into the powder housing, and a mist supply pipe coupled to the inside of the powder housing. It is composed of a differential valve tube with differential valve holes formed at regular intervals to control the differential spray supply of firefighting water, and it is easy to perform differential spray, differential spray/direct spray, direct beam and spray waterproofing by simply rotating the radioactive knob. It is intended to make it happen.

일반적으로 화재진화용 관창은 소방펌프에서 공급되는 소방수를 화원으로 분무하여 신속하고 용이하게 화재를 진화할 수 있도록 하는 것이다.In general, a nozzle for extinguishing a fire is to spray fire water supplied from a fire pump to a fire source so that the fire can be quickly and easily extinguished.

이상과 같은 화재진화용 관창은 관창몸체의 전방 측에 구비되어 화원으로 소방수를 분사하는 노즐부와 관창몸체의 후방 측에 구비되어 상기 노즐부로의 소방수 공급을 제어하는 레버형방수밸브, 관창몸체의 일측으로 구비되는 관창손잡이 및 소방수가 공급되는 소방호스가 연결되는 호스연결부로 구성되는 것이다.The fire extinguishing nozzle as described above includes a nozzle part provided on the front side of the nozzle body and spraying fire water to the fire source, a lever type waterproof valve provided on the rear side of the nozzle body to control the supply of fire water to the nozzle part, and a nozzle part of the nozzle body. It consists of a nozzle handle provided on one side and a hose connection to which a fire hose supplied with fire water is connected.

상기 종래 화재진화용 관창은 소방차의 펌프에서 압송되는 소방수를 원거리의 화원에 대량으로 분사하여서 화재를 진압하는 것이다.The conventional fire extinguishing nozzle is to extinguish the fire by spraying a large amount of fire water pumped from the pump of the fire engine to a distant fire source.

한편, 종래의 관창은 대유량의 소방수만이 분사되게 구성되어 있어 화재진압과정에 대유량의 소방수로 인한 수손 피해가 발생하고, 가정용 유류 화재의 경우 화재를 키우게 되며, 산불화제의 경우 소방수로 인하여 불이 붙은 낙엽이 다른 곳으로 튕겨져 날아가서 산불이 번지는 경우가 발생하고 있는 문제점이 있어, 대한민국 특허 제10-1353445호 및 제10-2075290호 미스트 분무 기능을 갖는 화재진화용 관창이 개발되어 사용되었다.On the other hand, the conventional nozzle is configured to spray only a large flow of firefighting water, so water damage occurs due to a large flow of firefighting water during the fire suppression process, and in the case of a household oil fire, the fire grows, and in the case of a forest fire, due to firefighting water There is a problem that the fallen leaves on fire are thrown away and the forest fire spreads, so Korean Patent Nos. 10-1353445 and 10-2075290 fire nozzles with mist spray function were developed and used. .

이상과 같은 미스트 분무 기능을 갖는 화재진화용 관창은 화재발생시 대유량 분무에 의한 진화가 용이하지 않은 화재의 경우 저압의 소방수에 의하여 화원의 주변에 냉각과 복사열 차단, 산소 희박 효과를 유발하는 화염차단미스트막을 형성하여 유류 화재나 산불 등을 신속하고 용이하게 진화하며 연기나 복사열로부터 소방관을 보호할 수 있었다.In the case of a fire that is not easy to extinguish by a large flow of spray, the nozzle for fire extinguishing having the mist spray function as described above blocks the flame that causes cooling and radiant heat blocking around the fire source and oxygen dilution effect by low-pressure fire-fighting water when a fire occurs. By forming a mist film, it was possible to extinguish an oil fire or forest fire quickly and easily, and to protect firefighters from smoke or radiant heat.

그러나 상기한 바와 같은 종래의 화재진화용 관창은 소방수의 방수를 위한 화재진화용 관창과 소화폼의 방사를 위한 화재진화용 관창이 별도 구비되어 있어 화재 현장에 있어 화재에 대한 대응이 신속하고 원활하지 않은 문제점이 있었다.However, as described above, the conventional fire extinguishing nozzle is separately equipped with a fire extinguishing nozzle for water discharge of firefighters and a fire extinguishing nozzle for ejection of fire extinguishing foam, so it is difficult to respond quickly and smoothly to a fire at a fire site. There was a problem that wasn't there.

또한, 종래의 화재진화용 관창은 미분무가 명확하게 이루어지지 않고 미분무를 위한 노즐의 결합이 용이하지 않은 문제점이 있었다.In addition, conventional fire extinguishing nozzles have problems in that fine spraying is not clearly performed and it is not easy to combine nozzles for fine spraying.
