Description
Technical field:
The utility model relates to a kind of fire fighting extinguisher, is specifically related to a kind of fine mist spray head that is used for portable water mist fire extinguisher.Belong to fire-fighting fire extinguishing equipment technical field.
Background technology
Owing to breathe out the ozone layer in the imperial serial extinguishing chemical heavy damage earth atmosphere, thereby threaten human survival.Therefore the developmental research of seeking its substitute products is just actively developed in world wide.Thin water smoke with its fire extinguishing rapidly, water consumption is low, to characteristics such as protection object safety, environmentally safes, by industrially developed country as the main substitute of breathing out imperial serial extinguishing chemical.The various extinguishing mechanisms that involve in the fine mist fire-fighting.These mechanism comprise three leading mechanism and two secondary mechanism.Leading mechanism is: heat absorption, displace oxygen and isolated radiation.Secondary mechanism is: reduce the combustible gas mixture concentration, reduce flame speed and accelerated combustion reaction.
Portable water mist fire extinguisher is compared with common portable carbon dioxide, dry powder extinguisher, belongs to advanced clean and effective fire extinguishing new product.Portable water mist fire extinguisher has overcome the shortcoming that water mist system commonly used can not put out the deep-seated fire and the fire that blocks is arranged, and can put out category-A, D class and part category-B fire, and can be used for protection often has the people place.
At present, the formation of the thin water smoke of portable water mist fire extinguisher mainly realizes that by rotary and collision type shower nozzle atomizing effect is generally undesirable under the lower situation of pressure.Consider the characteristics of portable water mist fire extinguisher self, atomizer must be under the situation that pressure constantly changes, and stablely sprays thin water smoke constantly, and requires to spray and concentrate, and jet length is far away.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can be under the situation that pressure constantly changes, stablely spray thin water smoke constantly, and require to spray and concentrate the fine mist spray head that is used for portable water mist fire extinguisher that jet length is far away.
The purpose of this utility model is achieved in that a kind of fine mist spray head that is used for portable water mist fire extinguisher, it is characterized in that it comprises housing, nozzle, atomizing core and sealing gasket,
Center, described housing rear end is opened counterbore and internal thread is set, and front end is provided with a cavity and internal thread is set, and counterbore is connected with cavity, and nozzle is installed in the housing front end cavity, sets sealing gasket between cavity bottom and the nozzle rear end face,
Described spray nozzle front end has several jet holes, the rear portion of each jet hole is a cylindrical hole, cylindrical hole and jet hole are by a conical surface transition, the atomizing core is housed in the cylindrical hole, atomizing core front end has some skewed slots, and atomizing core front end contacts with the conical surface in the cylindrical hole, and the rear cylinder of the core that atomizes is greater than forward cylinder, two planes are cut in the corresponding both sides of rear cylinder, just form two passages after the core that atomizes like this is installed in the cylindrical hole and are used to into water.
During the work of this fine mist spray head, water flows in the cavity of shower nozzle by the jet hose of fire extinguisher, then through the passage that forms between atomizing core side and the cylindrical hole hole wall and the gap between core front end cylinder and the cylindrical hole of the atomizing skewed slot of flowing through, form the high speed rotary water current, by the jet hole ejection, be atomized into thin water smoke.
The utility model fine mist spray head has a plurality of small nozzles, and the injection direction of each small nozzle is all identical, and the mist field of Chan Shenging just concentrates on the shower nozzle front region like this, and has higher momentum on the spout direction, can be injected into larger distance.
All there is an atomizing core each small nozzle the inside of this fine mist spray head, each atomizing core front end has some skewed slots, water is passing through skewed slot on the atomizing core under the effect of pressure, form the high speed rotary water current, the high speed rotary water current is through less jet hole ejection, have higher muzzle velocity simultaneously, current just are stretched like this, and then are broken into fine mist.This structure can be issued to atomizing effect preferably in the lower situation of pressure, and the mist field distribution is even.This fine mist spray head is installed on the portable water mist fire extinguisher, has the atomization and the fruit of putting out a fire preferably.
In sum, the thin water smoke of the utility model shower nozzle ejection concentrates on the shower nozzle Way out, and jet length is far away, and the thin water smoke of ejection is evenly distributed in the zone of action, and can reach good atomizing effect under lower pressure, the fire-fighting efficiency height.Satisfy the instructions for use of hand fire extinguisher, and pressure when reducing its mist field characteristic change little.
