Fig. 3 is the partial enlarged drawing of Fig. 2；
In accompanying drawing, the labelling of each part is as follows：1st, pipe joint, 2, filter, 3, nozzle, 4, jet pipe, 5, air entry, 6, gas
Change chamber, 7, spout, 8, clash into spring, 9, support, 10, regulating bolt, 11, fire protection pipeline.
Specific embodiment
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clearly defining.
A kind of dual-purpose shower nozzle of air suction type water mists foam, including base, the top of described base be and fire protection pipeline 11 even
The pipe joint 1 connecing；The filter 2 of the open column shape that the inside of described base is fixedly connected sequentially from top to bottom, nozzle 3 and penetrate
Flow tube 4；In the lower section within described base, it is provided with a gasification chamber 6, described gasification chamber 6 top offers and described jet pipe 4
The opening communicating, described gasification chamber 6 bottom offers the spout 7 of injection water mists or foam；If offering on described base
Dry air entry 5, described air entry 5 is located at described jet pipe 4 periphery.
In described base outer cover equipped with support 9, described support 9 is matched with described base, fixes shock spring 8,
The regulating bolt 10 adjusting the described axial length clashing into spring 8 is installed in the bottom centre of described support 9.
Some pores are offered on the outer wall of described jet pipe 4, described pore is located at the top of described jet pipe 4, leans on
Closely described nozzle 3, is provided with air cavity in the outside of described jet pipe 4, pore described in UNICOM and described air entry 5.
The operation principle of the present invention：
When there is the condition of a fire in protection zone, first passing through this dual-purpose shower nozzle and spraying water mists.The high heat capacity coefficient of water and high vapour
Change hot coefficient and can absorb big calorimetric from flame, and due to water droplet diameter very little, compared with the water of same volume, greatly
Increased surface area greatly, strengthen heat absorption capacity, rapid reduction scene temperature simultaneously reduces dense smoke.Now personnel can speedily carry out rescue work safely
And withdraw flame range, decrease loss as far as possible on the premise of ensureing personnel's life security.While water mists control the condition of a fire,
Add the foam dope mixing of corresponding proportion in water mists solution, foam solution is sprayed by dual-purpose shower nozzle, foam solution foams
Cover on burning things which may cause a fire disaster surface, completely cut off the contact with air for the burning things which may cause a fire disaster, reach effect of fire extinguishing completely.
Fine water mist fire-extinguishing system to be accomplished is merged with froth fire extinguishing system, and dual-purpose shower nozzle is necessary for being fully achieved thin water
While fog spray head technical specification, foam solution can be sprayed and reach the effect of foaming.
This dual-purpose shower nozzle, material all using 316L rustless steel, meet simultaneously fresh water, sea water, foam solution using will
Ask, the places such as naval vessel can be applied to.Dual-purpose operating pressure at sprinkler is 0.6 ~ 1.2MPa, flow 25 ~ 33L/min, water mists microgranule
0.99≤300 μm of diameter DV, filtering accuracy≤Φ 1mm, interface adopts G1 writing brush screw thread, and atomizing angle can adjust spiral shell by bottom
The covering that bolt 10 to realize this occasion to the regulation clashing into spring 8 requires.
When the medium of 0.6 ~ 1.2MPa enters shower nozzle from fire protection pipeline 11, medium is formed in jet pipe 4 by nozzle 3 and penetrates
Stream, carry out mixing concussion by air entry 5 and air afterwards, after gasification chamber 6 after spout 7 forms jet again shock
Spring 8 produces resonance, ultimately forms water mists or frothing foam sprays fire extinguishing.Wherein, as shown in figure 3, on the outer wall of jet pipe 4
Open up pore, air, after air entry 5 suction, is resorbed to jet by the air cavity between jet pipe 4 outer wall and air entry 5
In pipe 4, strengthen the mixing concussion between air and medium, make water mists or foam medium more uniform.
The dual-purpose shower nozzle of air suction type water mists foam of the present invention, is a kind of new and effective fire extinguishing sprayer, for water mists and
The merging of froth fire extinguishing system has very high practical value and economic worth, can be widely applied to prevent and eliminate fire
Place.
The foregoing is only embodiments of the invention, not thereby limit the present invention the scope of the claims, every using this
Equivalent structure or equivalent flow conversion that bright description and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
