Description
Technical field
The present invention relates to a kind of waterfog head, more particularly to a kind of mesolow fine mist spray head and its spray method.
Background technology
Water Mist Fire Extinguishing Technique is put out a fire the 1940s for steamer.Since the beginning of the 1990s in order to seek substitute halo
The preferable extinguishing chemical of alkane 1301,1211, some developed countries study in succession and manufacture fine spray extinguisher, and it is imitated in fire extinguishing
Fruit, environmental protection, secondary disaster loss etc. Integrated comparative, better than traditional fire-smothering gear and water spray, Water spray
Extinguishing device.Therefore, fine spray extinguisher is by wide popularization and application.
Fine mist spray head is an important part in fine mist fire-fighting, its size and fire extinguishing to water droplet
Effect have very big influence.Fine mist spray head is generally divided into high-pressure type fine mist spray head and mesolow type fine mist spray head.
As hydraulic pressure P>During 3.5Mpa, referred to as high-pressure type fine mist spray head；As hydraulic pressure P<During 3.5Mpa, referred to as mesolow type water mists spray
Head.High-pressure water mist spray head of today, due to hypertonia, cause the required precision of fine mist spray head higher, difficulty of processing is big,
Cost of manufacture is high；Secondly, High-Pressure Water has very serious erosion effect to high-pressure water mist spray head, so as to cause heavy pressure fine spray
The service life of shower nozzle is shorter.And traditional mesolow fine mist spray head atomizing effect is poor, extinguishing property is bad.
The content of the invention
To solve the above mentioned problem of prior art, it is an object of the invention to provide a kind of good extinguishing effect, processing and manufacturing
Simply, service life longer mesolow fine mist spray head and its spray method.
To achieve the above object, technical scheme is as follows：
A kind of mesolow fine mist spray head and its spray method, including：Shower nozzle outer barrel, atomization fan, annular spray pipe, electricity
Motivation, fan shaft, three pin fixed supports, water-supply-pipe, cock of water drain, locknut, three-way connection, screen pack；The atomization
Fan is arranged on the fan shaft right-hand member, and the annular spray pipe is fixed on the left of the atomization fan, the motor peace
On the cover plate on the left of the shower nozzle outer barrel, described cover plate is provided with air admission hole, described three-way connection one end and described defeated
Water pipe connects, and another both ends and annular spray pipe threaded connection, the water-supply-pipe are fixed on the spray with the locknut
On head outer barrel, the cock of water drain and the screen pack are installed on the water-supply-pipe.
According to the present invention, the annular spray pipe is having equally distributed circular water spray close to the atomization fan side
Hole, the annular spray pipe are the annular pipelines do not closed, and screw thread, the annular spray pipe profit are provided with the both ends do not closed
It is fixed on the three pin fixed support on the inside of the shower nozzle outer barrel.
According to the present invention, the fan shaft is exactly the power output rotating shaft of motor, the fan shaft and the electricity
Speed change gear is not provided among the power output shaft of motivation, one end of the fan shaft is provided with keyway and screw thread to be connected
The atomization fan.
According to the present invention, the flabellum of the atomization fan and the angle of axis are β, and β size general control is on 15 ° of left sides
It is right.
The method of work of a kind of mesolow fine mist spray head of the present invention and its spray method is as follows：
(1) motor is opened, the fan shaft rotates at a high speed, so as to drive the atomization fan to rotate at a high speed；
(2) cock of water drain is opened, water sprays from the hole for water spraying of the annular spray pipe, is sprayed on the described of rotation at a high speed
On atomization fan, because the atomization fan of high speed rotation collides with the water sprayed, water can be atomized into water mists；Its
Secondary, because the atomization fan of high speed rotation can produce centrifugal force, under the influence of centrifugal force, water can be thrown to the shower nozzle
The inwall collision of the inwall of outer barrel, water and the shower nozzle outer barrel, so as to strengthen atomizing effect；Finally, due to the atomization fan
High speed rotation can also produce one air-flow from left to right, the water mists being atomized into obtained in the presence of air-flow one it is larger
Initial velocity and be ejected.
The beneficial effect that a kind of mesolow fine mist spray head of the present invention and its spray method can obtain is：
(1) because the invention belongs to mesolow fine mist spray head, the requirement to the water pump of supply water is relatively low.It is in addition, relatively low
Erosion effect of the hydraulic pressure to fine mist spray head it is smaller, therefore the service life of shower nozzle is longer.
(2) there is the present invention atomizing of the small water droplet of atomization fan collision and centrifugal force to get rid of small water droplet to shower nozzle outer barrel
Inwall and then the double atomization effect that shock is produced with shower nozzle outer tube inner wall, atomizing effect are more preferable.
(3) atomizing power source of the invention is provided by motor, compared to traditional thin water that atomizing power is provided by water pump
Fog spray head, be atomized formation water smoke obtain momentum it is bigger, water mists are easier access to firebase, are gone out so as to substantially increase
Fiery effect.
(4) structure of the invention is simple, easy to process, manufacturing cost is relatively low.

Embodiment
The embodiment of the present invention is described in detail below.
As shown in figure 1, a kind of the mesolow fine mist spray head and its spray method of the present invention include shower nozzle outer barrel 1, it is atomized
Fan 2, annular spray pipe 3, motor 4, fan shaft 5, triangle fixed support 6, water-supply-pipe 7, cock of water drain 8, locknut
9, three-way connection 10, screen pack 11.
The motor is opened, the fan shaft rotates at a high speed, drives the atomization fan to rotate at a high speed；In the ring
Shape sparge pipe is provided with the hole for water spraying close to the side of the atomization fan, opens the cock of water drain, and water is from the hole for water spraying
Eject, be sprayed at a high speed on the atomization fan of rotation, because the atomization fan of high speed rotation is sent out with the water sprayed
Raw collision, water can be atomized into water mists；Secondly as the atomization fan of rotation can produce centrifugal force at a high speed, centrifuging
In the presence of power, water can be thrown to the inwall of the shower nozzle outer barrel, the inwall collision of water and the shower nozzle outer barrel, so as to strengthen mist
Change effect；Finally, due to the high speed rotation of the atomization fan can also produce one air-flow from left to right, the thin water being atomized into
Mist obtains a larger initial velocity and is ejected in the presence of air-flow.
It should be appreciated that embodiment described herein is merely to illustrate and explain the present invention, it is not used to
The limitation present invention.
