Abstract

The utility model relates to a water mist spray head, comprising a nozzle body and a spray head seat which are screwed by a screw and an inner chamber equipped with a spray core. The water inlet end of the spray core is equipped with a central water inlet opening which is communicated with the nozzle body inner chamber through the radical hole of the middle part, the water discharging end is a station conical body which is matched with the inner cone surface of the ejector nozzle of the nozzle body which is connected with the tangential diversion trench which is uniformly distributed along the circumferential direction. Serving as a key part of the water mist fire suppressing system, the utility model can create uniform water mist whose average particle diameter is smaller than 100 um. The utility model has simple structure, collapsible nozzle and spray core, convenient repairing and cleaning, good fire extinction effect when used in fire extinction and saving fire extinguishing water.

Description

Fine mist spray head
Technical field:
The utility model relates to a kind of shower nozzle, the fine mist spray head that particularly a kind of fire-fighting is used.
Background technology:
In recent years since gas extinguishing system in cost of installation and use, safeguard, tackle the defective that aspects such as fire resume combustion and environmental protection exist, breathe out imperial product and be substituted gradually.Fine water mist fire-extinguishing system is as a kind of new technology, new product, because its water-saving, pollution-free, superiority such as cost is low, obtained insider's very big concern, now be widely used on the boats and ships, and just progressively be used between confined space, fry dried food ingredients motor house and oil storage thereof and fuel oil, gas fired-boiler room, heart as fine water mist fire-extinguishing system---fine mist spray head, its atomization have directly determined the outlet capacity that goes out of fine water mist fire-extinguishing system.Existing fine mist spray head is because its structure more complicated, the processing cost height, and the water smoke particle diameter is thicker, and operating pressure is higher, has to a certain degree limited the go out development of water system of thin water smoke.
The utility model content:
The purpose of this utility model is to provide a kind of fine mist spray head, as the key component of fine water mist fire-extinguishing system, can produce uniformly, average grain diameter reaches the following thin water smoke of 100um.
For achieving the above object, the utility model adopts following technical proposals:
A kind of thin water utilities shower nozzle is spun by screw thread and inner chamber settles the spray core to constitute by nozzle body and nozzle boss, it is characterized in that the water inlet end that sprays core has the inlet opening, center, and the radial hole through its middle part is communicated with the nozzle body inner chamber; And to be the platform bullet cooperate with the spout end inner conical surface of nozzle body in its water side, and have circumferentially uniform tangential flow guiding groove to be communicated with the spout of nozzle body.
The internal thread of above-mentioned spray core by its external screw thread and nozzle body revolves joins.
Leave platform taper minor air cell between the front end face of above-mentioned spray core and the arrival end of spout, the inner conical surface of the center line of tangential flow guiding groove and platform taper minor air cell is tangent.
2~12 tangential flow guiding grooves are arranged on the above-mentioned spray core.
1~12 nozzle of being made up of nozzle body and spray core is housed on the above-mentioned nozzle boss.
The utility model has following conspicuous substantive distinguishing features and advantage compared with prior art: the spray core in the utility model has uniform tangential flow guiding groove, makes liquid enter platform taper minor air cell and produces rotating vortex, and liquid sprays along spout then.The centrifugal force that its eddy current rotation produces overcomes surface tension of liquid, be broken into silk or banded, outwards be extended to liquid film, at a high speed after the ejection, be broken into little droplet under pneumatic action, the reciprocation of centrifugal atomizing and speed atomizing has formed the water mist particle of average grain diameter below 100um.The utility model is simple in structure, atomizing effect is good, nozzle, the spray core all detachable, be convenient to maintenance, clean, the spray cored structure of its uniqueness can produce even, ultra-fine water smoke, as the key position of fine water mist fire-extinguishing system, can improve the fire extinguishing effect of fine water mist fire-extinguishing system greatly, save water for fire extinguishing, bring into play the extinguishing ability of fine water mist fire-extinguishing system better, save cost.
Description of drawings:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the nozzle arrangements schematic diagram of Fig. 1 example.
Fig. 3 is the spray cored structure schematic diagram of Fig. 1 example.
The specific embodiment:
A preferred embodiment of the present utility model is: referring to Fig. 1, Fig. 2 and Fig. 3, this fine mist spray head is spun by screw thread by nozzle body 3 and nozzle boss 1 and inner chamber settles spray core 2 to constitute, the water inlet end of spray core 2 has inlet opening, center 10, and the radial hole 4 through its middle part is communicated with nozzle body 3 inner chambers 9; And to be platform taper 6 cooperate with the spout end inner conical surface of nozzle body 3 in its water side, and have circumferentially uniform tangential flow guiding groove 5 to be communicated with the spout 8 of nozzle bodies 3.Above-mentioned spray core 2 revolves by the thread in inner cavity of its external screw thread and nozzle body 3 joins.Leave platform taper minor air cell 7 between the front end face of above-mentioned spray core 2 and the arrival end of spout 8, the inner conical surface of the center line of tangential flow guiding groove 5 and platform taper minor air cell 7 is tangent.2~12 tangential flow guiding grooves 5 are arranged on the above-mentioned spray core 2.1~12 nozzle of being made up of nozzle body 3 and spray core 2 is housed on the above-mentioned nozzle boss 1.
This fine mist spray head is nozzle specially used as fine water mist fire-extinguishing system, the water inlet of nozzle boss 1 is connected the high-pressure water of fire extinguishing system, then water under high pressure enters nozzle body 3 inner chambers 9 through the centre bore 10 and the radial hole 4 of spray core 2, tangential flow guiding groove 5 from spray core 2 flows into minor air cell 7 then, produce fast rotational, from spout 8 ejections of nozzle body 3, form thin water smoke and spray to zone on fire at last, produce desirable cooling and blocking radiant heat effect, reach the purpose that effectively stamps out a fire rapidly.
