Abstract

The invention provides a double-phase-flow fire-extinguishing nozzle. The double-phase-flow fire-extinguishing nozzle comprises a pipe casing and a nozzle, wherein the nozzle is arranged on the bottommost part of the pipe casing; the pipe casing is internally provided with a hollow water inlet pipe and an air inlet pipe is arranged above the pipe casing; the lower parts of the water inlet pipe and the air inlet pipe are provided with a water nozzle connector and a water-air flange disc respectively; a water nozzle fixed seat is connected below the water-air flange disc; a thread is formed on the lower outer surface of the water nozzle fixed seat and a fixed seat nut is screwed on the thread. According to the double-phase-flow fire-extinguishing nozzle provided by the invention, the air inlet pipe can be connected with an external nitrogen pipe net and the water inlet pipe can be connected with an external water supply pipe net, so that the air and the water can be supplied at the same time; a flow collection ring is fixedly connected with the nozzle by the fixed seat nut to form the complete double-phase-flow nozzle; a water dispersion column in the nozzle can disperse the water sprayed by the water nozzle and the air pressure of nitrogen is used for atomizing and spraying a water-nitrogen mixture from a spraying hole after the dispersion, so that the fire-extinguishing effect is improved and the double-phase-flow fire-extinguishing nozzle is easy to mount and convenient to maintain.

Description

A kind of two-phase flow fire extinguishing sprayer
Technical field
The present invention relates to a kind of fire extinguishing sprayer, be specifically related to a kind of fire extinguishing sprayer of two-phase flow for fire-fighting system.
Background technology
At present, for fire-fighting system commonly used three kinds of shower nozzles are arranged, the first is the ability of swimming shower nozzle; The second is gas tip; The third is the gas mixing type water shower nozzle.Although the application of the first ability of swimming shower nozzle is very wide, and structure is also very simple, but after one section breaking out of fire, water can affect to environment, and range of application is also more limited, the second gas tip is many a kind of products of applying at present, its feature is to be widely used in office building, in fire extinguishing or fire prevention system that market etc. are relatively sealed, and structure is also very simple, effect might as well, but effect is not just too desirable for the fire extinguishing system of some Code in Hazardous Special Locations, and should also know one section not thorough because putting out a fire for the first time, spot fire is even more serious, the third gas mixing type water shower nozzle, it is the mode of having utilized the pressure differential of water and nitrogen, water and nitrogen mixing jetting are out put out a fire, and fire extinguishing better effects if, it is also a kind of novel fire-fighting mode in all fire extinguishing systems on the market, but more existing so hybrid shower nozzles, although adopted a kind of like this mode, go design, but the fire extinguishing effect is general, and real during for some soft large fire, can not guarantee fully fire is extinguished, structure is also very complicated simultaneously, safeguard also inconvenience, and price is also very high.
Summary of the invention
Purpose of the present invention, overcome the deficiencies in the prior art exactly, provide a kind of can be easy to maintenance, good extinguishing effect and the safe and reliable fire extinguishing sprayer of the two-phase flow for fire extinguishing system.
In order to achieve the above object, the invention provides a kind of two-phase flow fire extinguishing sprayer, comprise pipe box and nozzle, described pipe box foot is provided with nozzle, the water inlet pipe and the outer top position of pipe box that in described pipe box, are provided with hollow are provided with air inlet pipe, described water inlet pipe and air inlet pipe bottom are separately installed with water fittings and aqueous vapor ring flange, and described aqueous vapor ring flange below is connected with the water nozzle holder, and described water nozzle holder lower surface is provided with on screw thread and screw thread and is screwed with the holder nut.
For the convenient fire extinguishing sprayer of installing, described pipe box is provided with the screw holder outward, and described screw holder is provided with on screw thread and screw thread and is screwed with locking nut.
In order conveniently to control water and nitrogen, mix, in the middle of described water nozzle holder, be the water hole of a hollow, and evenly be provided with a plurality of air passing holes around water hole.
In order to make the air-tightness between pipe box and water inlet pipe better, described water inlet pipe and pipe box top position are provided with bonding pad.
For the better atomization of the nitrogen that air inlet pipe is entered, described water fittings bottom is provided with collecting ring, and is provided with nozzle between collecting ring and holder nut.
For the water entered being dispersed, directly over described nozzle bottom, position is fixed with a cylindrical aproll post.
In order further the water nitrogen mixture being sprayed evenly from spray orifice, and to guarantee the shower nozzle protected area, describedly centered by the aproll post, evenly outwards to be provided with the round spray orifice of two circles, and the equal outward-dipping one-tenth obtuse angle of the angle of spray orifice, described obtuse angle is between 90 to 180.
The invention has the beneficial effects as follows: air inlet pipe can be connected with outside nitrogen pipe network, water inlet pipe can be connected with outside water supply network, air feed and water supply simultaneously, by the holder nut, collecting ring is fixedly connected with nozzle, form complete two-phase flow shower nozzle, and the aproll post of nozzle the inside can disperse the water of water nozzle ejection, disperse the rear air pressure of nitrogen that utilizes the water nitrogen mixture is sprayed from the spray orifice atomization, not only improved the usefulness of fire extinguishing, and installed simple, easy to maintenance.
