Abstract
The invention discloses a fire-fighting water curtain device, which comprises a circular inner sleeve, wherein the joint end of the inner sleeve is provided with a joint screw thread; a plurality of water spray holes are annularly formed in the side face of the inner sleeve; a first sealing ring and a second sealing ring are arranged in front of and behind an annular ring formed by the water spray holes on the inner sleeve in the axial direction respectively; the periphery of the inner sleeve is provided with a control ring; and the inner surface of the control ring is provided with a control ring screw thread and a third sealing ring. According to the fire-fighting water curtain device disclosed by the invention, smog is diluted, fire spreading is prevented, and a rainwater curtain is formed, so that people can enter or leave fire fields under protection.
Description
Technical field
The invention belongs to the fire-fighting equipment field, be specifically related to a kind of water curtain device for fire-fighting.
Background technology
The scene of fire often be full of smoke, poison gas is bigger, influence the fire fighter near and implement the efficient of rescue.In addition, in the accident for some inflammable and explosive Hazardous Chemical Substances, press for urgent cooling and isolate the fire-fighting rescue equipment of these inflammable and explosive Hazardous Chemical Substances.
The moisture that hydraulic giant penetrates is water column and screen shape mist emission mode, can in fire extinguishing, form water curtain and can effectively absorb heat and absorption flue dust, thereby protection fire-fighting lance Water curtain system be designed for the safety of protection people and property.
In the time of the fire extinguishing of column mist emission mode, the heat radiation that the water source produces forces the fire fighter to keep certain distance, and therefore influence fire extinguishing; Screen shape water curtain can be in fire extinguishing, thereby prevents heat radiation and can send to the distance that fresh air reaches the protection burning things which may cause a fire disaster to the fire fighter, makes fire extinguishing more rapidly with efficient.
Summary of the invention
For overcoming deficiency of the prior art, the objective of the invention is to propose a kind of water curtain device for fire-fighting, this device is simple in structure, and is easy to use, the effect that can play dilution, prevent something from spreading smog, poison gas; The Hazardous Chemical Substances of scene of fire is played the effect of urgent cooling, isolation.
A kind of water curtain device for fire-fighting of the present invention; The interior cover that comprises annular; The cohesive end of cover is provided with the linking screw thread in said, is provided with several hole for water sprayings with ring-type on the side of interior cover, in put the annular ring that hole for water spraying forms axial front and back be respectively equipped with first sealing ring and second sealing ring; The periphery of interior cover is provided with a control circle, and control is enclosed inner face and is provided with control circle screw thread and the 3rd sealing ring.
Preferably, put in said and be provided with the limited screw hole, limited screw is provided with little spring in the hole.
Preferably, be provided with the spacing globule that diameter is 2mm in the said limited screw hole.
Beneficial effect: water curtain device for fire-fighting of the present invention, be used to dilute smog, prevent fire spreading, form the rainwater curtain, get into or withdraw the scene of fire with the protection personnel.
