Abstract
The invention relates to a wide-angle type water mist fire extinguishing spray head for a hydraulic generator stator and a work method. A traditional fire extinguishing head is a spraying type water column, and spray is formed through small water drops generated by three inclined holes in the spray head. The spraying angle ranges from 70 degrees to 80 degrees. The spraying area is small, the fire extinguishing effect is poor, water consumption is large, and material consumption is large as well. The wide-angle type water mist fire extinguishing spray head comprises a spray head body (1); a water inlet (3) and a water outlet (2) are formed in the two ends of the spray head body respectively, and two blades (4) are fixed to the water inlet; the two blades are distributed in a crossed shape; and the spray head body is provided with an outer thread (5). The wide-angle type water mist fire extinguishing spray head is used for an accessory of a fire extinguishing device.
Description
technical field:
the present invention relates to fire-fighting equipment, be specifically related to a kind of hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment.
background technology:
invention fine water mist fire-extinguishing system utilizes press water, drips by the water mists of special nozzle specially used formation a kind of fixed fire extinguishing system that particle carries out putting out a fire or protecting cooling.Under operating pressure 0.4 ~ 0.8MPa, water mists drips average diameter and is less than 300 μm.The water of same volume, after the atomization of water particulate, surface area increases, and more easily carry out heat heat absorption, cooling combustion reacts, and the water particulate absorbing heat is more easily vaporized, and volume increases more than 1700 times.The generation of steam, can either dilute the oxygen in guard plot, and suffocate combustion reaction, effectively can control heat radiation again, so fine mist fire-fighting dominant mechanism is cooling efficiently and anoxia asphyxia double action.
tradition fire extinguishing sprayer is fountain water column, and be the little water droplet formation spray being produced water by the angling hole of three on shower nozzle, spray angle is that between 70 ° ~ 80 °, projected area is little, extinguishing effect is not good, and water consumption is large, and consumptive material is also large.
summary of the invention:
the present invention seeks to propose a kind of hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment.
above-mentioned object is achieved through the following technical solutions:
a kind of hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment, its composition comprises: head body, and described head body two ends are respectively water inlet, delivery port, and described water inlet fixes 2 blades, blade described in 2 is right-angled intersection distribution, and described head body is provided with external screw thread.
described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment, the operating pressure of described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment is 0.4 ~ 0.8MPa.
described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment, the spray angle of described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment is 110 ° ~ 120 °.
described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment, described shower nozzle body is the stainless steel tube of φ 20.5mm, and described stainless steel tube material is 1Cr18Ni9Ti.
a method of work for the hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment that one of claim 1-4 is described, this comprises the steps:
described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment is connected with generator external water system, supply water when described water system starts, current enter in described hydraulic generator stator wide-angle type Water spraying nozzle for extinguishment through water inlet, current change flow velocity and flow direction through the impact of blade therebetween, impel current to prolong spray angle and are 110 ° ~ 120 ° and spray from delivery port.
the invention has the beneficial effects as follows:
the present invention utilizes press water, drips by the water mists of special nozzle specially used formation a kind of fixed fire extinguishing system that particle carries out putting out a fire or protecting cooling.Under operating pressure 0.4 ~ 0.8MPa, water mists drips average diameter and is less than 300 μm.The water of same volume, after the atomization of water particulate, surface area increases, and more easily carry out heat heat absorption, cooling combustion reacts, and the water particulate absorbing heat is more easily vaporized, and volume increases more than 1700 times.The generation of steam, can either dilute the oxygen in guard plot, and suffocate combustion reaction, effectively can control heat radiation again, so dominant mechanism of the present invention is cooling efficiently and anoxia asphyxia double action.
water consumption of the present invention is only 1/4 of original Water spray shower nozzle water consumption, decreases the capacity of outside fire fighting supply, avoids the secondary disaster that a large amount of draining causes simultaneously, and fire-fighting technique is advanced, to human body fanout free region, on environment without impact.
this shower nozzle of the present invention has unique blade design, and spray angle is between 110 ° ~ 120 °, and projected area is wide, good extinguishing effect.
consumptive material of the present invention is few, and the pipeline of water receiving can change φ 42mm stainless steel tube into by original φ 76mm stainless steel tube, reduces production cost.
